(i) unless made in accordance with the provisions hereof;

(ii) until, upon compliance with such reasonable requirements as the Canadian Trustee may prescribe, such transfer is recorded on the register maintained by the Canadian Trustee pursuant to Section 2.9; and

(iii) until all governmental or other charges arising by reason of such transfer have been paid.

Aura will be entitled, and may direct the Canadian Trustee, to refuse to recognize any transfer, or enter the name of any transferee, of any Rights on the register kept by the Canadian Trustee, if such transfer would constitute a violation of the securities laws of any jurisdiction or the rules, regulations or policies or any Regulatory Authority having jurisdiction, it being acknowledged and agreed that the Rights shall be freely trading securities in Canada and freely transferable securities in the United States (other than by persons who are, or have been within the preceding 90 days or three months, "affiliates" of Aura, as such term is defined in Rule 144 under the U.S. Securities Act).

(b) No duty shall rest with the either Trustee to determine compliance of the transferee or transferor of any Rights with applicable securities laws or requirements of Regulatory Authorities. Each Trustee may assume for the purposes of this Indenture that the address on the register of Holders of any Holder is the actual address of such Holder and is also determinative of the residence of such Holder and that the address of any transferee to whom any Rights or other securities deliverable in connection with any Rights are to be registered, as shown on the transfer document, is the actual address of the transferee and is also determinative of the residency of the transferee.

2.14 Ownership of Rights

(a) Aura and the Trustees may deem and treat the registered Holder of any Rights Certificate as the absolute owner of the Right represented by this Indenture for all purposes and Aura and the Trustees shall not be affected by any notice or knowledge to the contrary, except where Aura or the applicable Trustee is required to take notice by statute or by order of a court of competent jurisdiction. For greater certainty, subject to applicable law, neither Aura nor either Trustee shall be bound to take notice of or see to the execution of any trust, whether express, implied or constructive, in respect of any Right, and may transfer any Right in accordance with Section 2.10 on the direction of the Person registered as Holder thereof, whether named as trustee or otherwise, as though that Person were the beneficial owner thereof.

(b) If the Required Holders do not deliver such a Dispute Notice on or prior to the expiry of the Dispute Period, the Holders will be deemed to have accepted that the Payment Condition has not been met, and Aura and its Affiliates will have no further obligation with respect to the Rights or the CVR Payment Amount.

(d) Aura shall work in good faith together with Required Holders who have provided a Dispute Notice to resolve the dispute set out in this Indenture on a mutually satisfactory basis for not less than 30 days, following which the dispute may be referred to arbitration pursuant to Section 5.2.

(a) Subject to Section 5.1, all disputes, disagreements, controversies, questions or claims arising out of or relating to this Indenture ("Disputes"), with the exception of Disputes involving the U.S. Trustee, will be finally determined by a sole Arbitrator (the "Arbitrator") under the International Commercial Arbitration Act, 2017 (Ontario) (the "International Act"). In addition:

(i) for certainty, article 34 in Schedule 2 of the International Act will apply to the arbitration of a Dispute;

(ii) Aura, the Required Holders and the Canadian Trustee (collectively, the "Arbitration Parties") shall together appoint the Arbitrator. If the Arbitration Parties cannot agree, the Arbitrator will be appointed by a judge of the Superior Court of Justice of Ontario on the application of any Arbitration Party on notice to all the other Arbitration Parties. No individual will be appointed as Arbitrator unless he or she agrees in writing to be bound by the provisions of this Section 5.2;


(iii) the law of the Province of Ontario, and the federal laws of Canada applicable therein, will apply to the substance of all Disputes, with the exception of disputes involving the U.S. Trustee;

(v) the language to be used in the arbitration will be English;

(vi) the Arbitrator, after giving the Arbitration Parties an opportunity to be heard, will determine the procedures for the arbitration of the Dispute, provided that those procedures will include an opportunity for written submissions and responses to written submissions by or on behalf of all Arbitration Parties, and may also include an opportunity for exchange of oral argument and any other procedures as the Arbitrator considers appropriate. However, if the Arbitration Parties agree on a code of procedures or on specific matters of procedure, that agreement will be binding on the Arbitrator;

(vii) the Arbitrator will have the right to determine all questions of law and jurisdiction, including questions as to whether a Dispute is arbitrable, and will have the right to grant legal and equitable relief including injunctive relief and the right to grant permanent and interim injunctive relief, and final and interim damages awards. The Arbitrator will also have the discretion to award costs, including reasonable legal fees and expenses, reasonable expert's fees and expenses, reasonable witnesses' fees and expenses pre-award and post-award interest and costs of the arbitration, provided that the Arbitrator will not make an award of costs on a distributive basis;

(viii) the Arbitration Parties intend, and will take all reasonable action as is necessary or desirable to ensure, that there be a speedy resolution to any Dispute, and the Arbitrator will conduct the arbitration of the Dispute with a view to making a determination and order as soon as possible;

(ix) the Arbitration Parties desire that any arbitration should be conducted in strict confidence and that there will be no disclosure to any Person of the existence or any aspect of a Dispute except as is necessary for the resolution of the Dispute. Any proceedings before the Arbitrator will be attended only by those Persons whose presence, in the opinion of any Arbitration Party or the Arbitrator, is reasonably necessary for the resolution of the Dispute. All matters relating to, all evidence presented to, all submissions made in the course of, and all documents produced in accordance with, an arbitration under this Article, as well as any arbitral award, will be kept confidential and will not be disclosed to any Person without the prior written consent of all the Arbitration Parties except as required in connection with an application of an Arbitration Party under article 34 or article 35 in Schedule 2 of the International Act, by applicable laws, or by an order of an Arbitrator; and


(x) Subject to article 33 in Schedule 2 of the International Act, all awards and determinations of the Arbitrator will be final and binding on the Arbitration Parties, and there will be no appeal of any such award or determination on any grounds.

(b) Prior to the appointment of the Arbitrator, the Arbitration Parties may apply to the courts for interim relief. A request for interim relief by an Arbitration Party to a court will not be considered to be incompatible with Section 5.2(a) or as a waiver of that provision.

(c) At the request of any Arbitration Party, the Arbitrator may take any interim measures that the Arbitrator considers necessary in respect of the Dispute, including measures for the preservation of assets, the conservation of goods or the sale of perishable goods. The Arbitrator may require security for the costs of those measures.

(d) The law with respect to limitation periods that would apply to a court proceeding also applies to an arbitration, as if the arbitration were an action and a claim made in the arbitration were a cause of action.

5.3 Waiver of Default

Upon the occurrence of any Event of Default that is continuing the Required Holders shall have the power (in addition to the powers exercisable by Extraordinary Resolution) by requisition in writing to instruct the Trustees to waive any such Event of Default and the Trustees shall thereupon waive the default upon such terms and conditions as shall be prescribed in such requisition, provided that no delay or omission of the Trustees or of the Holders, as applicable, to exercise any right or power accruing upon any Event of Default shall impair any such right or power or shall be construed to be a waiver of any such Event of Default or acquiescence in this Indenture and provided further that no act or omission either the Trustees or the Holders in the premises shall extend to or be taken in any manner whatsoever to affect any subsequent Event of Default under this Indenture or the rights resulting therefrom.

5.4 Control by Holders

The Holders of a majority in of the Rights outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustees or exercising any trust or power conferred on the Trustees. However, the Trustees may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustees in personal liability or expose the Trustees to out of pocket expenses, or that the Trustees determines in good faith may be unduly prejudicial to the rights of Holders not joining in the giving of such direction, and may take any other action it deems proper that is not inconsistent with any such direction received from Holders. For purposes of this Section 5.4, the U.S. Trustee shall comply with Trust Indenture Act Section 316(a) in making any determination of whether the required holders of outstanding Rights have concurred in any request or direction of the Trustees to pursue any remedy available to the Trustees or the holders with respect to this Indenture or the Rights or otherwise under the law. The Trustees may request indemnification and funding prior to accepting any direction from the Holders.

5.8 Trustee May File Proofs of Claim

The Trustees may file proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustees (including any claim for the compensation, expenses, disbursements and advances of the Trustees, their agents and counsel, and any other amounts due the Trustees hereunder) allowed in any judicial proceedings relating to Aura or its creditors or property, and are entitled and empowered to collect, receive and distribute any money, securities or other property payable or deliverable upon any such claims. Any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to either Trustee and, if the Trustees consent to the making of such payments directly to the Holders, to pay to the Trustees any amount due to them for the reasonable compensation, expenses, disbursements and advances of the Trustees, their agents and counsel, and any other amounts due the Trustees hereunder. Nothing in this Indenture shall be deemed to empower the Trustees to authorize or consent to, or accept or adopt on behalf of any Holder, any plan of reorganization, arrangement, adjustment or composition affecting the Rights or the rights of any Holder thereof, or to authorize the Trustees to vote in respect of the claim of any Holder in any such proceeding.

(b) If, at any such meeting, the Holders holding at least 25% of the then outstanding Rights are not present in person or by proxy within 30 minutes after the time appointed for the meeting, then the meeting, if convened by or on the requisition of the Holders, shall be dissolved; but in any other case it shall stand adjourned to such date, being not less than seven nor more than 45 days later, and to such place and time as may be appointed by the chairman. Not less than two days' prior notice shall be given of the time and place of such adjourned meeting in the manner provided in Article 7. Such notice must state that at the adjourned meeting the Holders present in person or by proxy shall form a quorum but it shall not be necessary to set forth the purposes for which the meeting was originally called or any other particulars.

6.13 Minutes

Minutes of all resolutions and proceedings at every meeting of Holders shall be made and duly entered in books to be from time to time provided for that purpose by the Canadian Trustee at the expense of Aura, and any such minutes, if signed by the chairman or secretary of the meeting at which such resolutions were passed or proceedings had, or by the chairman or secretary of the next succeeding meeting (if any) of the Holders, shall be prima facie evidence of the matters in this Indenture stated and, until the contrary is proved, every such meeting in respect of the proceedings of which minutes shall have been made shall be deemed to have been duly held and convened, and all resolutions passed thereat or proceedings taken thereat, to have been duly passed and taken.

Further, should a Trustee, in its sole judgment, determine at any time that its acting under this Indenture has resulted in its being in non-compliance with any applicable anti-money laundering, antiterrorist or economic sanctions legislation, regulation or guideline, then it shall have the right to resign on the 10th Business Day following delivery of written notice to Aura, provided (i) that such Trustee's written notice shall describe the circumstances of such non-compliance; and (ii) that if such circumstances are rectified to such Trustee's satisfaction within such 10 day period, then such resignation shall not be effective.

(a) Prior to the earlier of the Full Payment Date and the Termination Date, each one of the following events is an event of default (each, an "Event of Default") under this Indenture:

(i) Aura shall fail to observe or perform in any material respect any covenant, condition or agreement contained in this Indenture or in respect of the Rights and such failure shall continue unremedied for a period of 120 days after written notice has been given to Aura by the Trustees or to Aura and the Trustees by any Required Holders specifying such failure and requiring it to be remedied;

(ii) a court having competent jurisdiction over Aura entering a decree or order (i) for relief in respect of Aura following the filing of any petition, application or other proceeding against or in respect of Aura by or on behalf of a Person (other than Aura) under any applicable bankruptcy, insolvency or other similar law now or thereafter in effect, or (ii) appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of Aura or for any substantial part of its property or ordering the winding up or liquidation of its affairs, and in case of (i) or (ii), such decree or order remaining unstayed and in effect for a period of 30 consecutive days; or

(iii) Aura voluntarily (i) commencing or filing any petition, application or other proceeding under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, (ii) consenting to the entry of an order for relief under any proceeding initiated against or in respect of Aura by or on behalf of a Person (other than Aura) under any such law, (iii) consenting to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of Aura or for any substantial part of its property, or (iv) making any general assignment for the benefit of its creditors.

(b) If an Event of Default described in Section 10.1(a)(ii) or Section 10.1(a)(iii) above occurs, then the Rights in aggregate will thereafter automatically be converted into and represent an unsecured claim for the outstanding balance of the CVR Payment Amount plus any additional amount determined to be due and payable to Holders by Aura pursuant to any arbitration under Section 5.2, regardless of the satisfaction of the Payment Conditions (for greater certainty, such unsecured claim shall rank pari passu with other unsecured claims of Aura).


(c) If an Event of Default described in Section 10.1(a) occurs and is continuing, then the Canadian Trustee by notice to Aura or the Canadian Trustee upon the written request of Required Holders by notice to Aura and to the Trustees, shall bring the matter to binding arbitration in accordance with Section 5.2 to protect the rights of the Holders, including to obtain payment for any amounts then due and payable, which amounts shall bear interest at the Default Rate from the date of the occurrence of the applicable Event of Default until payment is made to the Canadian Trustee.

(d) The foregoing provisions are subject to the condition that if, at any time after the Canadian Trustee has delivered a notice of arbitration, and before any judgment or decree for the payment of the moneys due has been obtained or entered, Aura has paid or deposited with the Canadian Trustee a sum sufficient to pay all such amounts which have become due and payable (with interest upon such overdue amount at the Default Rate to the date of such payment or deposit) and an amount sufficient to cover reasonable compensation to the Trustees, their agents, attorneys and counsel, and all other reasonable out-of- pocket expenses and liabilities incurred and all advances made, by the Trustees, and if any and all Events of Default under this Indenture have been cured, waived or otherwise remedied as provided in this Indenture, then and in every such case the Required Holders, by written notice to Aura and to the Trustees, may waive all Events of Default with respect to the Rights, but no such wavier or rescission and annulment will extend to or will affect any subsequent Event of Default or shall impair any right consequent thereof.

(e) Aura shall provide the Trustees with written notice of the occurrence of any Event of Default under this Indenture within three Business Days of Aura becoming aware of any such Event of Default.

ARTICLE 11
GENERAL PROVISIONS

11.1 Execution

This Indenture shall be valid, binding, and enforceable against a party only when executed and delivered by an authorized individual on behalf of the party by means of (i) any electronic signature permitted by the federal Electronic Signatures in Global and National Commerce Act, state enactments of the Uniform Electronic Transactions Act, and/or any other relevant electronic signatures law, including relevant provisions of the Uniform Commercial Code (collectively, "Signature Law"); (ii) an original manual signature; or (iii) a faxed, scanned, or photocopied manual signature.  Each electronic signature or faxed, scanned, or photocopied manual signature shall for all purposes have the same validity, legal effect, and admissibility in evidence as an original manual signature. Each party hereto shall be entitled to conclusively rely upon any faxed, scanned, or photocopied manual signature, or other electronic signature, of any party and shall have no duty to investigate, confirm or otherwise verify the validity or authenticity thereof.  This Indenture may be executed in any number of counterparts, each of which shall be deemed to be an original, but such counterparts shall, together, constitute one and the same instrument.  For avoidance of doubt, original manual signatures shall be used for execution or indorsement of writings when required under the Uniform Commercial Code or other Signature Law due to the character or intended character of the writings.


11.2 Formal Date

This Indenture shall be referred to as having the date first written above, regardless of the actual date of execution.

11.3 Satisfaction and Discharge of Indenture

Upon the Termination Date, this Indenture shall cease to be of any force and effect and the Trustees, on demand of and at the cost and expense of Aura and upon delivery to the Trustees of a certificate of Aura stating that all conditions precedent to the satisfaction and discharge of this Indenture have been complied with, shall execute instruments as requested by Aura acknowledging satisfaction of and discharging this Indenture. Notwithstanding the foregoing, the indemnities provided to the Trustees by Aura under this Indenture shall remain in full force and effect and survive the termination of this Indenture.

11.4 Provisions of Indenture and Rights for the Sole Benefit of Parties and Holders

Nothing in this Indenture or in the Rights Certificates, expressed or implied, shall give or be construed to give to any Person other than the parties thereto and the Holders, as the case may be, any legal or equitable right, remedy or claim under this Indenture, or under any covenant or provision in this Indenture or in this Indenture, all such covenants and provisions being for the sole benefit of the parties hereto and the Holders.

11.5 Withholding

Each of Aura and the Trustees shall be entitled to deduct and withhold from any cash amounts payable pursuant to this Indenture such amounts as Aura or the Trustees, as the case may be, is required to deduct and withhold with respect to such payment under the Income Tax Act (Canada) or any provision of federal, provincial, state, local or foreign tax law (including, for the avoidance of doubt, U.S. federal income tax law if applicable). In lieu of withholding such amounts Aura and the Trustees shall be entitled to otherwise recover from or to require a Holder to provide for such applicable taxes. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the relevant Holder, provided that such withheld amounts are actually remitted to the appropriate taxing authority.

Aura will presume that payments to a Holder that is a "U.S. Shareholder" as defined in the Letter of Transmittal, based on such definition, are subject to backup withholding Taxes at the rate of 24 percent unless such Holder delivers to Aura and the Canadian Trustee at the time or times prescribed by law and at such time or times reasonably requested by Aura and the Canadian Trustee such documentation prescribed by applicable law and such additional documentation reasonably requested by Aura and the Canadian Trustee as may be necessary for Aura and the Canadian Trustee to comply with its tax obligations and to determine that such Holder is not subject to such backup withholding or to determine the required amount to deduct and withhold from such payment.


11.6 U.S.A. Patriot Act

The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the U.S. Trustee is required to obtain, verify and record information that identifies each Person that establishes a relationship or opens an account with the U.S. Trustee. Aura agrees that it will provide the U.S. Trustee with such information as the U.S. Trustee may reasonably request in order for the U.S. Trustee to satisfy the requirements of the U.S.A. Patriot Act. The provisions of this Section 11.6 are for the sole and exclusive benefit of the U.S. Trustee and no failure by Aura to comply with, or any breach of, this Section 11.6 shall constitute an Event of Default or other default with respect to the Rights or under this Indenture, nor shall any Person other than Aura and the U.S. Trustee have any rights under this Section 11.6.

11.7 Legal Holidays

If any scheduled Payment Date falls on a day that is not a Business Day, then notwithstanding any other provision of this Indenture, the payment to be made on such Payment Date will be made on the next succeeding Business Day with the same force and effect as if made on such Payment Date, and no additional interest will accrue solely as a result of such delayed payment.

LETTER TO BLUESTONE SECURITYHOLDERS

November 12, 2024

Dear Bluestone Securityholders:

The Board of Directors (the "Board") of Bluestone Resources Inc. (the "Company" or "Bluestone") invites you to attend the special meeting (the "Meeting") of the holders (the "Bluestone Shareholders") of common shares of the Company ("Bluestone Shares") and the holders (the "Bluestone Optionholders", collectively with the Bluestone Shareholders, the "Bluestone Securityholders") of options to purchase Bluestone Shares to be held on December 19, 2024 at 10:00 a.m. (Vancouver Time) at Suite 3500 - 1133 Melville Street, Vancouver, British Columbia V6E 4E5.

The Arrangement and Consideration

At the Meeting, the Bluestone Securityholders will be asked to consider and, if deemed advisable, pass a special resolution (the "Arrangement Resolution") to approve an arrangement (the "Arrangement"), in accordance with the terms of an arrangement agreement entered into by the Company and Aura Minerals Inc. ("Aura") on October 25, 2024, as amended by a first amending agreement dated November 4, 2024, and as further amended by a second amending agreement dated November 11, 2024 (as amended, the "Arrangement Agreement"), pursuant to which Aura agreed to acquire all of the issued and outstanding Bluestone Shares that it does not already own by way of a statutory plan of arrangement (the "Plan of Arrangement") under section 288 of the Business Corporations Act (British Columbia).

Under the terms of the Arrangement Agreement, which was negotiated at arm's length, each Bluestone Shareholder (other than Bluestone Shareholders validly exercising their dissent rights) will receive the following for each Bluestone Share held, at such Bluestone Shareholder's election, on the closing of the Arrangement: (A) $0.2870 in cash (the "Cash Consideration") or (B) 0.0183 common shares in the capital of Aura (each common share, an "Aura Share") (the "Share Consideration"), each subject to pro-ration based on a maximum of 1,393,736 Aura Shares to be issued pursuant to the Plan of Arrangement (collectively, the "Initial Consideration"). Bluestone Shareholders who do not make an election will be deemed to have elected for the Cash Consideration in respect of each Bluestone Share held.

In addition, Bluestone Shareholders will receive one non-interest bearing contingent value right (a "CVR") for each Bluestone Share held, with each CVR entitling its holder to receive, subject to the satisfaction of the CVR Payment Conditions (defined below), up to $0.2120 (the "Contingent Consideration", and together with the Initial Consideration, the "Consideration"). The Contingent Consideration will be payable until the CVR Termination Date (as defined below) pursuant to the following schedule: (A) upon the announcement of commercial production at the Cerro Blanco Project (the "First Payment Condition"), 33.33% of the Contingent Consideration, being $0.0707; (B) upon the Cerro Blanco Project still being in production on the date that is one year from the date which the First Payment Condition was satisfied (the "Second Payment Condition"), 33.33% of the Contingent Consideration, being $0.0707; and (C) upon the Cerro Blanco Project still being in production on the date that is two years from the date which the First Payment Condition was satisfied (the "Third Payment Condition", collectively with the First Payment Condition and the Second Payment Condition, the "CVR Payment Conditions"), the balance of the Contingent Consideration, being $0.0706; provided that the CVR Payment Conditions have been satisfied prior to the date that is twenty (20) years following the Effective Date (as defined below) (the "CVR Termination Date").

2024 Special Meeting of Securityholders

Pursuant to the Arrangement, each Bluestone Option outstanding as of the beginning of the day (Vancouver time) (the "Effective Time") on the date that the Arrangement is completed (the "Effective Date") (whether vested or unvested) shall be disposed of and surrendered by the Bluestone Optionholder without any act or formality on its or their part and without any liability in exchange for a cash payment from Bluestone equal to the amount set out in the Plan of Arrangement (which represents the value of such Bluestone Option as of October 24, 2025 using the "Black Scholes" valuation model calculated as per industry standard practice) (the "Bluestone Option Termination Payment"). At the Effective Time, all Bluestone Options outstanding immediately prior to the Effective Time shall be cancelled.

Benefits of the Arrangement to Bluestone Shareholders

In reaching their conclusion that the Arrangement is in the best interest of the Company, the Board considered and relied upon a number of factors, including among other things, the following:

 Compelling Value - The total value of the Consideration to be received by Bluestone Shareholders pursuant to the Arrangement Agreement, assuming the Consideration is paid in full, represents a premium to the trading value of the Bluestone Shares of approximately 51% premium to the Company's spot share price and approximately 40% premium to the 25-day volume weighted average trading price of the Bluestone Shares as at October 24, 2024.

 Cash Consideration - The Cash Consideration to be received under the Arrangement Agreement provides Bluestone Shareholders with certainty of value, immediate liquidity, and removes the risks associated with the Company remaining an independent public entity amidst an uncertain outlook for the Company's Cerro Blanco Project in Guatemala.

 Ownership in a Leading Americas-Focused Gold and Copper Producer - Pursuant to the Share Consideration, Bluestone Shareholders will participate in any future increases in value in the Aura Shares that might result from future growth and the potential achievement of Aura's long-term plans. Aura is a high-growth, multi-jurisdiction, gold and copper producer focused on the operation and development of gold and base metal projects in the Americas, with gold and copper projects in Brazil, Mexico, and Honduras, and future projects that are at different stages of development in Brazil and Colombia. The Aura Shares comprising the Share Consideration offer immediate liquidity, along with near- and medium-term growth, complemented by Aura's technical, operational and financial capability.

 Potential Additional Consideration - The Contingent Consideration provides the Bluestone Shareholders with an opportunity to receive an additional $0.2120 per Bluestone Share if commercial production at the Cerro Blanco Project commences, subject to the terms of the Rights Indenture and the Arrangement Agreement.

 Bluestone Fairness Opinion - The Bluestone Fairness Opinion (as defined and discussed in the enclosed Circular) received by the Board and the Special Committee (as defined below) on October 25, 2024 provided that, as of the date thereof and subject to the assumptions, limitations and qualifications contained therein, the Consideration to be received by Bluestone Shareholders pursuant to the Arrangement is fair from a financial point of view to Bluestone Shareholders.

Voting Support Agreement

Each member of the Board and senior officers of Bluestone, in addition to certain Bluestone Securityholders, owning in aggregate approximately 40% of the outstanding Bluestone Securities, have entered into voting support agreements with Aura, pursuant to which, among other things, they have agreed to vote or cause to be voted all of the Bluestone Securities held or controlled by them in favour of the Arrangement Resolution.

2024 Special Meeting of Securityholders

Recommendation of the Board and the Special Committee

A special committee of the Board, comprised of independent directors of the Board (the "Special Committee") has advised the Board that, after careful consideration of such matters as it considered relevant, as more fully described under the heading "The Arrangement - Reasons for the Arrangement" contained in the enclosed management information circular dated November 12, 2024 (the "Circular"), including, among other things, (i) the terms and conditions of the Arrangement Agreement; (ii) the benefits and risks associated with the Arrangement; (iii) other strategic alternatives and options available to the Company; (iv) its evaluation of the Arrangement with management and the Special Committee's legal and financial advisors, including receipt of the Bluestone Fairness Opinion; and (v) the impact of the Arrangement on other stakeholders of the Company, the Special Committee has unanimously determined that the Arrangement is in the best interests of Bluestone and is fair from a financial point of view to Bluestone Shareholders, and has unanimously recommended to the Board that it authorize and approve Bluestone entering into the Arrangement Agreement and the performance of its obligations thereunder and recommend to the Bluestone Shareholders and the Bluestone Optionholders that they vote in favour of the Arrangement Resolution.

The Board, after careful consideration of such matters as it considered relevant, as more fully described under the heading "The Arrangement - Reasons for the Arrangement" contained in the enclosed Circular, including, among other things, a thorough review of the Arrangement Agreement, and taking into account the best interests of Bluestone and after evaluating the Arrangement with management and Bluestone's legal and financial advisors, including receipt of the Bluestone Fairness Opinion, and upon the unanimous recommendation of the Special Committee, the Board has unanimously determined the Arrangement is in the best interests of Bluestone and is fair from a financial point of view to Bluestone Shareholders and that it is advisable and in the best interests of Bluestone to approve the entering into and execution and delivery of the Arrangement Agreement and the performance of its obligations thereunder, and has unanimously approved the Arrangement. Accordingly, the Board unanimously recommends that the Bluestone Shareholders and the Bluestone Optionholders vote FOR the Arrangement.

Election

If you are a registered Bluestone Shareholder, in order to make your election to receive the Cash Consideration or the Share Consideration (subject to pro-ration and adjustment in accordance with the Arrangement Agreement), you must submit the enclosed letter of transmittal and election form (the "Letter of Transmittal").

The Letter of Transmittal contains other procedural information, including information with respect to making an election for the Cash Consideration or Share Consideration relating to the Arrangement and should be reviewed carefully.

Registered Bluestone Shareholders must submit their Letter of Transmittal by 4:30 p.m. (Toronto time) on December 16, 2024, or, if the Meeting is adjourned or postponed, no later than 72 hours (excluding Saturdays, Sundays and statutory holidays in British Columbia) before the adjourned Meeting is reconvened or the postponed Meeting is convened (the "Election Deadline"). Please refer to the enclosed Circular and the Letter of Transmittal for additional information. If a Bluestone Shareholder does not make an election in accordance with the instructions in the Letter of Transmittal, such Bluestone Shareholder will be deemed to have elected for the Cash Consideration in respect of each Bluestone Share held. Beneficial Bluestone Shareholders (i.e., if you hold Bluestone Shares through a broker, custodian, nominee or other intermediary) should follow the instructions provided by your intermediary to make your election.

Bluestone Shareholders who choose not to vote, or to vote against the Arrangement Resolution, may still make an election to receive the Cash Consideration or the Share Consideration by completing the election form included with the Letter of Transmittal accompanying the Circular and submitting such form to Computershare Investor Services Inc. (the "Depositary") prior to the Election Deadline. Bluestone Shareholders whose Bluestone Shares are registered in the name of a broker, investment dealer or other intermediary should contact that broker, investment dealer or other intermediary for instructions and assistance in delivery of the share certificate(s) or direct registration system advice(s), also known as "DRS Advice(s)", representing those Bluestone Shares and making an election with respect to the form of Consideration they wish to receive.

Your vote is very important regardless of the number of Bluestone Shares or Bluestone Options you own. If you are a registered Bluestone Shareholder or Bluestone Optionholder and you are unable to attend the Meeting, we encourage you to complete, sign, date and return the applicable proxy accompanying the Circular so that your Bluestone Shares or Bluestone Options, as the case may be, can be voted at the Meeting (or at any adjournments or postponements thereof) in accordance with your instructions.

On behalf of the Board and the Special Committee, I thank all Bluestone Shareholders and Bluestone Optionholders for their continued support and we look forward to receiving your endorsement for this transaction at the Meeting.

Yours very truly,

(signed) "Peter Hemstead"

At the Effective Time, all Bluestone Options outstanding immediately prior to the Effective Time shall be cancelled.


2024 Special Meeting of Securityholders

Q. What is a CVR?

A: The CVRs are a form of contingent consideration entitling Bluestone Shareholders to receive up to $0.2120 for each Bluestone Share held or issued under the Arrangement, as applicable, payable if the CVR Payment Conditions are satisfied prior to the CVR Termination Date.

For additional information on the CVRs, please see "The Rights Indenture" and "Risk Factors - Risks Related to CVRs".

Q. How can I transfer my CVRs?

A: The CVRs will be governed by the Rights Indenture (as defined herein and attached as Appendix J to this Circular) and will not be subject to resale restrictions in Canada and the United States (other than restrictions that apply to persons who are, have been within 90 days of the Effective Time, or at the Effective Time become, "affiliates" of Aura, as such term is defined in Rule 144 under the U.S. Securities Act). The CVRs will not be listed on an exchange, but may be transferred pursuant to the transfer procedures set out in the Rights Indenture.

Q. How will I receive payment for the CVRs?

A: Assuming the CVR Payment Conditions are met prior to the CVR Termination Date, the Canadian Trustee under the Rights Indenture (as defined herein and attached as Appendix J to this Circular) will thereafter pay the respective holder of the CVRs (each such holder, a "CVR Holder"), the applicable CVR Payment (as defined herein), by cheque issuable pursuant to the Rights Indenture in respect of the CVRs held by such CVR Holders.

Q. How do I elect to receive my Consideration under the Arrangement

A: Each Registered Bluestone Shareholder will have the right to elect in the accompanying Letter of Transmittal to receive either (i) $0.2870 in cash or (ii) 0.0183 Aura Shares, subject to pro-ration based on the Aggregate Share Consideration for each Bluestone Share held. If you fail to make a proper election prior to the election deadline, December 16, 2024, or, if the Meeting is adjourned or postponed, no later than 72 hours (excluding Saturdays, Sundays and statutory holidays in British Columbia) before the adjourned Meeting is reconvened or the postponed Meeting is convened (the "Election Deadline"), or chose not to make an election, you will be deemed to have elected for the Cash Consideration in respect of each of your Bluestone Shares.

Beneficial Bluestone Shareholders should contact their Intermediary for instructions and assistance in delivery of the share certificate(s) or DRS Advice(s) representing their Bluestone Shares and making an election with respect to the form of Consideration they wish to receive.

For additional information, including information regarding how the Depositary will send you the Consideration, please see "The Arrangement - Exchange of Bluestone Securities".

Q. If I make an election to receive Cash Consideration or Share Consideration for all of my Bluestone Shares held, will I receive all cash or all Aura Shares, respectively?

A: If you elect to receive the Share Consideration for all of your Bluestone Shares held, your election will most likely be pro-rated and you will likely receive some amount of cash. This is because the issuance of the Share Consideration under the Arrangement is subject to the Aggregate Share Consideration. The extent of the pro-ration of your election will depend on the degree to which other Bluestone Shareholders elect to receive cash or Aura Shares.


2024 Special Meeting of Securityholders

Q. Do I need to send my Bluestone Share certificates or DRS Advices to vote?

A: You are not required to send your certificate(s) or DRS Advice(s) representing Bluestone Shares to validly cast your vote in respect of the Arrangement Resolution.

We encourage Registered Bluestone Shareholders to complete, sign, date and return the enclosed Letter of Transmittal, together with their Bluestone Share certificate(s) or DRS Advice(s) representing Bluestone Shares (if applicable) in accordance with the instructions set out in the proxy, as soon as possible, as this will assist in arranging for the prompt exchange of their Bluestone Shares if the Arrangement is completed. Additionally, in order to make an election to receive the Cash Consideration or the Share Consideration, you will need to return your Bluestone Share certificates or DRS Advice(s) representing Bluestone Shares, along with a properly completed and duly executed Letter of Transmittal, prior to the Election Deadline. If you fail to make a proper election prior to the Election Deadline (being the third Business Days (as defined herein) prior to the Meeting) or choose not to make an election, you will be deemed to have elected for the Cash Consideration in respect of each Bluestone Share held.

Where Bluestone Shares are evidenced only by a DRS Advice, there is no requirement to first obtain a share certificate for those Bluestone Shares. Only a properly completed and duly executed Letter of Transmittal, accompanied by the applicable DRS Advice(s), is required to be delivered to the Depositary in order to surrender those Bluestone Shares under the Arrangement.

Do not send your Letter of Transmittal and share certificate(s)/DRS Advice(s) to Bluestone.

Q. When can I expect to receive the Consideration?

A: Assuming completion of the Arrangement, if you hold your Bluestone Shares through an Intermediary, then you are not required to take any action and the Consideration you are entitled to receive will be delivered to your Intermediary though procedures in place for such purposes between CDS & Co. or similar entities and such Intermediaries. You should contact your Intermediary if you have any questions regarding this process.

In the case of Registered Bluestone Shareholders, as soon as practical after the date that the Arrangement is completed, assuming due delivery of the required documentation, including the applicable certificate(s) or DRS Advice(s) representing Bluestone Shares and a duly and properly completed Letter of Transmittal, Aura will cause the Depositary to forward the Rights Certificate (as defined herein) representing the CVRs, the certificate(s)/DRS Advice(s) representing Aura Shares and/or the cheque representing the Cash Consideration, as applicable, to which the Registered Bluestone Shareholders are entitled by first class mail, at the offices of the Depositary or by wire transfer.

The method used to deliver the Letter of Transmittal and any accompanying certificates representing Bluestone Shares is at the option and risk of the Registered Bluestone Shareholder, and delivery will be deemed effective only when such documents are actually received. Bluestone recommends that the necessary documentation be hand delivered to the Depositary at its office(s) specified on the last page of the Letter of Transmittal and a receipt obtained; otherwise, the use of registered mail with return receipt requested, properly insured, is recommended. A Bluestone Shareholder whose Bluestone Shares are registered in the name of a broker, investment dealer, bank, trust company or other nominee should contact that nominee for assistance in depositing those Bluestone Shares.

For additional information, including information regarding how the Depositary will send you the Consideration, please see "The Arrangement - Exchange of Bluestone Securities".

Q. What is the recommendation of the Board of Directors?

A: After taking into consideration the recommendation of the committee of independent directors of the Board (the "Special Committee") and such other matters as it considered relevant, including the factors described under the heading "The Arrangement - Reasons for the Arrangement", the Board has unanimously concluded that the Arrangement is in the best interests of the Company and fair from a financial point of view to Bluestone Shareholders and recommends that Bluestone Securityholders vote FOR the Arrangement Resolution to approve the Arrangement.


2024 Special Meeting of Securityholders

Q. Why is the Board of Directors making this recommendation?

A: In reaching their conclusion that the Arrangement is in the best interests of the Company, the Board considered and relied upon a number of factors, including among others, the following (for complete details, refer to the section, "The Arrangement - Reasons for the Arrangement"):

 Compelling Value - The total value of the Consideration to be received by Bluestone Shareholders pursuant to the Arrangement Agreement (as defined herein), assuming the Consideration is paid in full, represents a premium to the trading value of the Bluestone Shares of approximately 51% premium to the Company's spot share price and approximately 40% premium to the 25-day volume weighted average trading price of the Bluestone Shares as at October 24, 2024.

 Cash Consideration - The Cash Consideration to be received under the Arrangement Agreement provides Bluestone Shareholders with certainty of value, immediate liquidity, and removes the risks associated with the Company remaining an independent public entity amidst an uncertain outlook for the Company's Cerro Blanco Project in Guatemala.

 Ownership in a Leading Americas-Focused Gold and Copper Producer - Pursuant to the Share Consideration, Bluestone Shareholders will participate in any future increases in value in the Aura Shares that might result from future growth and the potential achievement of Aura's long-term plans. Aura is a high-growth, multi-jurisdiction, gold and copper producer focused on the operation and development of gold and base metal projects in the Americas, with gold and copper projects in Brazil, Mexico, and Honduras, and future projects that are at different stages of development in Brazil and Colombia. The Aura Shares comprising the Share Consideration offer immediate liquidity, along with near- and medium-term growth, complemented by Aura's technical, operational and financial capability.

 Potential Additional Consideration - The Contingent Consideration provides the Bluestone Shareholders with an opportunity to receive an additional $0.2120 per Bluestone Share if commercial production at the Cerro Blanco Project commences, subject to the terms of the Rights Indenture and the Arrangement Agreement.

 Bluestone Fairness Opinion - The Bluestone Fairness Opinion received by the Board and the Special Committee on October 25, 2024 provided that, as of the date thereof and subject to the assumptions, limitations and qualifications contained therein, the Consideration to be received by Bluestone Shareholders pursuant to the Arrangement is fair from a financial point of view to Bluestone Shareholders.

Q. As a Registered Bluestone Shareholder, what happens if I submit my Letter of Transmittal and the associated documentation, including my share certificate(s) or DRS Advice(s), and the Arrangement Resolution is not approved or the Arrangement is not completed?

A: If the Arrangement Resolution is not approved or if the Arrangement is not otherwise completed, your certificate(s) and/or DRS Advice(s) and any other documentation associated with your ownership of Bluestone Shares will be returned promptly to you by the Depositary.


2024 Special Meeting of Securityholders

Q. As a holder of Bluestone Options, what documentation do I need to submit to be able to receive my Bluestone Option Termination Payment?

A: Bluestone Optionholders do not need to submit any documentation in order to receive the Bluestone Option Termination Payment payable to them under the Arrangement.

Q. What vote is required at the Meeting to approve the Arrangement Resolution?

A: In order to become effective, the Arrangement must be approved by at least (i) 66⅔% of the votes cast by Bluestone Shareholders present or represented by proxy at the Meeting; (ii) 66⅔% of the votes cast by Bluestone Securityholders, voting together as a single class, present or represented by proxy at the Meeting; and (iii) a majority of the votes cast by Bluestone Shareholders other than votes attached to Bluestone Shares required to be excluded pursuant to MI 61-101.

Q. What voting rights do Bluestone Shares and Bluestone Options carry? How many votes do I have?

A: As at the Record Date, a total of 152,355,607 Bluestone Shares and 14,023,892 Bluestone Options were issued and outstanding. You are entitled to receive notice of, and vote at the Meeting or at any adjournment or postponement thereof, if you were a holder of Bluestone Shares or Bluestone Options on the Record Date. Each Bluestone Shareholder whose name is entered on the central securities register of Bluestone as at the close of business on the Record Date is entitled to one vote for each Bluestone Share registered in his, her or its name in respect of the Arrangement Resolution. Each Bluestone Optionholder whose name is on the applicable securities registers of the Company at the close of business on the Record Date is entitled to one vote for each Bluestone Option held in his, her or its name.

Q. Am I a Registered Bluestone Shareholder or a Beneficial Bluestone Shareholder?

A: Registered Bluestone Shareholders hold Bluestone Shares registered in their names and such Bluestone Shares are generally evidenced by a share certificate or DRS advice ("DRS Advice"). However, most holders of Bluestone Shares beneficially own their Bluestone Shares through a broker, custodian, nominee or other intermediary (an "Intermediary"). If your Bluestone Shares appear on an account statement provided by your bank, broker or financial advisor, you are, in all likelihood, a Beneficial Bluestone Shareholder. Beneficial Bluestone Shareholders should carefully follow the instructions of their Intermediaries, in addition to the instructions set forth in the Circular, to ensure that their Bluestone Shares are voted at the Meeting in accordance with their instructions and that their election to receive Cash Consideration and Share Consideration, subject to pro-ration, is made. Bluestone Shareholders who do not make such an election will be deemed to have elected for the Cash Consideration in respect of each Bluestone Share held.

Q. How do I vote?

A: There are different ways to submit your voting instructions depending on whether you are a Registered Bluestone Shareholder, a Beneficial Bluestone Shareholder or a Bluestone Optionholder:

 Registered Bluestone Shareholders: You must be a Registered Bluestone Shareholder as at the close of business on the Record Date to vote. You may vote in person or by proxy at the Meeting.

 Beneficial Bluestone Shareholders: You may vote or appoint a proxy using the VIF provided to you. Your vote or proxy appointment will be submitted by your bank, trust company, securities broker, trustee, custodian or other nominee who holds Bluestone Shares on your behalf to the Company.


2024 Special Meeting of Securityholders

 Bluestone Optionholders: You must be a registered holder of Bluestone Options as at the close of business on the Record Date to vote. You may vote in person or by proxy at the Meeting.

Whether or not you expect to attend the Meeting, we encourage you to vote your form of proxy as promptly as possible to ensure that your vote will be counted at the Meeting.

See also "When is the cut off time for delivery of proxies and internet and telephone voting?".

The persons named in the forms of proxy and voting instruction form are our directors and/or officers. However, as further described herein, you may choose another person to act as your proxyholder, including someone who is not a Bluestone Shareholder, by inserting such person's name in the space provided in the form of proxy or voting instruction form.

On the form of proxy, you may indicate either how you want your proxyholder to vote your Bluestone Securities, or you can let your proxyholder decide for you. If you have specified on the form of proxy how you want your Bluestone Securities to be voted on a particular matter (by marking FOR or AGAINST), then your proxyholder must vote your Bluestone Securities, accordingly. If you have not specified on the form of proxy how you want your Bluestone Securities to be voted on a particular matter, then your proxyholder can vote your Bluestone Securities as such proxyholder sees fit. Unless contrary instructions are provided, the voting rights attached to the Bluestone Securities represented by proxies received by the management of Bluestone will be voted IN FAVOUR OF the Arrangement Resolution.

The form of proxy confers discretionary authority with respect to: (i) amendments or variations to the matters of business to be considered at the Meeting; and (ii) other matters that may properly come before the Meeting. As of the date of this Circular, the management of Bluestone is not aware of any amendments, variations or other matters to come before the Meeting, other than the matters set forth in the Notice of Meeting included in this Circular. If, however, other matters properly come before the Meeting, the persons named in the form of proxy and voting instruction form will vote on them in accordance with their judgment, pursuant to the discretionary authority conferred upon them by the form of proxy with respect to such matters.

Beneficial Bluestone Shareholders should carefully follow all instructions provided by their Intermediaries to ensure that their Bluestone Shares are voted at the Meeting. See "Proxies and Voting - Beneficial Shareholder Voting".

Q. How will the votes be counted?

A: Computershare, Bluestone's transfer agent, counts and tabulates the proxies. Proxies are counted and tabulated by the transfer agent in such a manner as to preserve the confidentiality of the voting instructions of Registered Bluestone Shareholders and Bluestone Optionholders, subject to a limited number of exceptions.

Q. How do I appoint a third party as my proxyholder?

A: The following applies to Registered Bluestone Shareholders or Bluestone Optionholders who wish to appoint a person other than the management nominees set forth in the form of proxy as proxyholder, AND Beneficial Bluestone Shareholders who wish to appoint themselves as proxyholder to participate and vote at the Meeting.

You have the right to appoint any person or company you want to be your proxyholder. It does not have to be a Bluestone Shareholder or the person designated in the enclosed form(s). Simply indicate the person's name as directed on the enclosed proxy form(s) or complete any other legal proxy form and deliver it to Computershare within the time hereinafter specified for receipt of proxies.


2024 Special Meeting of Securityholders

Bluestone Shareholders or Bluestone Optionholders who wish to appoint a third-party proxyholder to attend or vote at the Meeting as their proxy and vote their Bluestone Shares or Bluestone Options, as the case may be, MUST submit their proxy (or proxies) or VIF, as applicable, appointing such third-party proxyholder in accordance with the instructions provided in the proxy or VIF, as applicable.

If you are a Beneficial Bluestone Shareholder and wish to attend or vote at the Meeting, you have to insert your own name in the space provided on the VIF sent to you by your Intermediary, follow all of the applicable instructions provided by your Intermediary. By doing so, you are instructing your Intermediary to appoint you as proxyholder. It is important that you comply with the signature and return instructions provided by your Intermediary.

Q. What if I return my proxy but do not mark it to show how I wish to vote?

A: If your proxy is signed and dated and returned without specifying your choice or is returned specifying both choices, your Bluestone Shares or Bluestone Options, as applicable, will be voted FOR the Arrangement Resolution in accordance with the recommendation of the Board.

Q. When is the cut-off time for delivery of proxies and internet and telephone voting?

A: Proxies sent by mail or courier must be delivered to Computershare not less than 48 hours (excluding Saturdays, Sundays and holidays) before the time of the Meeting or any adjournment or postponement thereof. In this case, assuming no adjournment or postponement, the proxy-cut off time is 10:00 a.m. (Vancouver time) on December 17, 2024. Online votes submitted via the internet at www.investorvote.com and votes submitted by telephone by calling 1-866-732-8683 (toll free in North America) or direct dial 312-588-4290 (outside North America) must also be submitted by 10:00 a.m. (Vancouver time) on December 17, 2024. The Chair of the Meeting, in his or her sole discretion, may accept late proxies or waive the deadline for accepting proxies.

Beneficial Bluestone Shareholders should complete and return their VIF well in advance of the Meeting, in accordance with the instructions in the VIF.

Q. As a Bluestone Securityholder, can I revoke my proxy or change my vote after I have submitted a signed proxy?

A: Yes. If you want to revoke your proxy (or proxies) after you have delivered it (them), you can do so by (a) signing a proxy bearing a later date and returning such form at any time before the proxy cut-off time, (b) signing a written statement which indicates, clearly, that you want to revoke your proxy and delivering the signed written statement to the registered office of Bluestone no later than 10:00 a.m. (Vancouver time) on December 17, 2024, or (c) in any other manner permitted by law.

Your proxy (or proxies) will only be revoked pursuant to (b) above if such proxy bearing a later date is received no later than 10:00 a.m. (Vancouver time) on December 17, 2024 (or if the Meeting is postponed or adjourned, by no later than 48 hours prior to the time of such postponed or adjourned meeting, excluding Saturdays, Sundays and holidays). If you revoke your proxy (or proxies) and do not replace it (or them) with another that is properly deposited before the proxy cut-off time, you can still vote your Bluestone Shares and/or Bluestone Options, but to do so you must attend the Meeting and follow the procedures for voting in person.

If you are a Beneficial Bluestone Shareholder and wish to revoke previously provided voting instructions, you should contact your Intermediary to discuss whether this is possible and what procedures you need to follow. The change or revocation of voting instructions by a Beneficial Bluestone Shareholder can take several days or longer to complete and, accordingly, any such action should be completed well in advance of the deadline given in the proxy or VIF by the Intermediary or its service company to ensure it is effective.


2024 Special Meeting of Securityholders

Q. In addition to the approval of Bluestone Securityholders, are there any other approvals required for the Arrangement?

A: Yes, the Arrangement requires the approval of the Court, the TSX Venture Exchange ("TSXV") and also is subject to certain Key Consents and Approvals (as defined herein), including the ICA Clearance (as defined herein) and the TIA Qualification (as defined herein). Further, the issuance of the Share Consideration by Aura is subject to the approval of the Toronto Stock Exchange ("TSX"). See "The Arrangement - Court Approval of the Arrangement" and "The Arrangement - Regulatory Approvals" in this Circular.

Q. Do any directors or executive officers of Bluestone have any interests in the Arrangement that are different from, or in addition to, those of the Bluestone Securityholders?

A: In considering the recommendation of the Board to vote in favour of the matters discussed in this Circular, Bluestone Securityholders should be aware that some of the directors and senior officers of Bluestone have interests in the Arrangement that are different from, or in addition to, the interests of Bluestone Securityholders generally. See "The Arrangement - Interests of Certain Persons in the Arrangement" in this Circular.

Q. Will the Bluestone Shares continue to be listed on the TSXV after the Arrangement is completed?

A: No. If the Arrangement is completed, Aura will acquire all of the issued and outstanding Bluestone Shares and Bluestone will become a wholly-owned subsidiary of Aura. Following the completion of the Arrangement, it is expected that the Bluestone Shares will be delisted from the TSXV and the OTCQB. Former Bluestone Shareholders who have elected to receive the Share Consideration will hold Aura Shares, which are listed on the TSX. The CVRs will not be listed on any stock exchange.

Q. How will I know when the Arrangement will be implemented?

A: The Effective Date will occur upon satisfaction or waiver of all of the conditions to the completion of the Arrangement. If the Required Securityholder Approval (as defined herein) is obtained at the Meeting, the Effective Date is expected to occur in January 2025. On the Effective Date, Bluestone and Aura will publicly announce that the conditions are satisfied or waived and that the Arrangement has been completed.

Q. Are there risks I should consider in deciding whether to vote for the Arrangement Resolution?

A: Yes. Bluestone Securityholders should carefully consider the risk factors relating to the Arrangement. Some of these risks include, but are not limited to: (i) there can be no certainty that all conditions precedent to the Arrangement will be satisfied; (ii) Bluestone Shareholders that elect the Share Consideration may be subject to pro-ration in accordance with the Arrangement; (iii) the number of Aura Shares to be received under an election to receive the Share Consideration is fixed and may not correlate to the Cash Consideration; (iv) market price of the Bluestone Shares and Aura Shares may be materially adversely affected if the Arrangement is not completed; (v) the Arrangement Agreement may be terminated in certain circumstances; (vi) the completion of the Arrangement is uncertain and Bluestone will incur costs even if the Arrangement is not completed; (vii) the Arrangement may divert the attention of Bluestone management; (viii) the Termination Fee (as defined herein) provided under the Arrangement Agreement may discourage other parties from attempting to acquire Bluestone; (ix) restrictions from pursuing business opportunities; (x) the Aura Shares to be issued in connection with the Arrangement may have a market value different than expected; (xi) directors and officers of Bluestone have interests in the Arrangement that may be different from those of Bluestone Securityholders generally; (xii) Aura and Bluestone may be the targets of legal claims, securities class action, derivative lawsuits and other claims; (xiii) CVR Holders may never receive the full CVR Payment Amount (as defined herein); (xiv) CVR Payment Amounts rank at parity with other unsecured claims of Aura; (xv) the CVRs will not be listed on any exchange; (xvi) the treatment of CVRs for U.S. federal income tax purposes is unclear; and (xvii) as a holder of Aura Shares, you will be subject to the risks associated with an investment in Aura. See "Risks Related to the Arrangement", "Information Concerning Aura" and "Information Concerning Aura Following the Arrangement" in this Circular.

Q. What are the Canadian income tax consequences of the Arrangement?

A: For a summary of certain material Canadian income tax consequences of the Arrangement, see "Certain Canadian Federal Income Tax Consideration" in this Circular.

Bluestone Securityholders in the United States are urged to consult their own tax and investment advisors with respect to their particular circumstances.

Q. Am I entitled to Dissent Rights?

A: If you are a Registered Bluestone Shareholder who duly and validly exercises Dissent Rights (as defined herein) in strict compliance with the dissent procedures contained in Division 2 of Part 8 of the BCBCA, as modified by the Interim Order, the Plan of Arrangement and any other order of the Court, and the Arrangement Resolution is approved, you will be entitled to be paid the fair value of your Bluestone Shares calculated as of the close of business on the day before the Arrangement Resolution was adopted. This amount may be the same as, more than or less than the value of the Consideration received by the Bluestone Shareholders under the Arrangement.

If you wish to dissent, you must (i) ensure that a written notice is received by Bluestone c/o Blake, Cassels & Graydon LLP, Suite 3500 - 1133 Melville Street, Vancouver, British Columbia V6E 4E5, Attention: Alexandra Luchenko, or by email to alexandra.luchenko@blakes.com by no later than 5:00 p.m. (Vancouver time) on the date that is not later than the day that is at least two days (excluding Saturdays, Sundays and holidays in the Province of British Columbia) prior to the Meeting (as it may be adjourned or postponed from time to time) as described under "The Arrangement - Dissenting Bluestone Shareholders' Rights"; and (ii) otherwise comply strictly with the provisions of Division 2 of Part 8 of the BCBCA as modified by the Interim Order, the Plan of Arrangement and any other order of the Court.

Failure to comply strictly with the requirements set forth in Division 2 of Part 8 of the BCBCA as modified by the Interim Order, the Plan of Arrangement and any other order of the Court may result in the loss of any right to dissent.

BLUESTONE RESOURCES INC.

MANAGEMENT INFORMATION CIRCULAR

Introduction

This Management Information Circular (the "Circular") is furnished in connection with the solicitation of proxies by and on behalf of management of Bluestone for use at the Meeting and any adjournment or postponement thereof. Other than the management of Bluestone and its authorized agents, no person has been authorized to give any information or make any representation in connection with the Arrangement or any other matters to be considered at the Meeting other than those contained in this Circular and, if given or made, any such information or representation must not be relied upon as having been authorized and should not be relied upon in making a decision as to how to vote on the Arrangement.

These Meeting materials are being sent to Registered Bluestone Shareholders and Beneficial Bluestone Shareholders, through Intermediaries, and to Bluestone Optionholders.

If you hold Bluestone Shares through an Intermediary, you should contact your Intermediary for instructions and assistance in voting and surrendering the Bluestone Shares that you beneficially own.

Information Contained in this Circular

The information contained in this Circular is given as at November 12, 2024, except where otherwise noted. This Circular does not constitute the solicitation of an offer to purchase any securities or the solicitation of a proxy by any person in any jurisdiction in which such solicitation is not authorized or in which the person making such solicitation is not qualified to do so or to any person to whom it is unlawful to make such solicitation.

Information contained in this Circular should not be construed as legal, tax or financial advice and Bluestone Shareholders and Bluestone Optionholders are urged to consult their own professional advisors in connection therewith.

Except where otherwise expressly provided, all amounts in this Circular are stated and will be paid in Canadian currency.

THIS CIRCULAR AND THE TRANSACTIONS CONTEMPLATED BY THE ARRANGEMENT AGREEMENT AND THE PLAN OF ARRANGEMENT HAVE NOT BEEN APPROVED OR DISAPPROVED BY ANY SECURITIES REGULATORY AUTHORITY NOR HAS ANY SECURITIES REGULATORY AUTHORITY PASSED UPON THE FAIRNESS OR MERITS OF SUCH TRANSACTIONS OR UPON THE ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED IN THIS CIRCULAR. ANY REPRESENTATION TO THE CONTRARY IS AN OFFENCE.

Information Concerning Aura

The information concerning Aura and its affiliates contained in this Circular has been provided by Aura for inclusion in this Circular. Although the Company has no knowledge that any statements contained herein taken from or based on such information provided by Aura are untrue or incomplete, the Company assumes no responsibility for the accuracy of such information, or for any failure by Aura or any of its affiliates or any of their respective representatives to disclose events which may have occurred or may affect the significance or accuracy of any such information but which are unknown to the Company. In accordance with the Arrangement Agreement, Aura provided the Company with all necessary information concerning Aura that is required by law to be included in this Circular and ensured that such information does not contain any misrepresentation concerning Aura or its affiliates.

Information for U.S. Bluestone Securityholders

The Company is a company existing under the laws of the Province of British Columbia, Canada. The solicitation of proxies and the transactions contemplated in this Circular are not subject to the proxy rules under the U.S. Exchange Act, and therefore this solicitation is not being effected in accordance with such rules. Accordingly, the solicitation and transactions contemplated in this Circular are made in the United States for securities of a Canadian issuer in accordance with British Columbia corporate laws and Securities Laws (as defined herein), and this Circular has been prepared in accordance with disclosure requirements applicable in Canada. Bluestone Shareholders and Bluestone Optionholders in the United States should be aware that disclosure requirements under Canadian laws are different from those of the United States applicable to proxy statements, prospectuses and registration statements. Bluestone Shareholders and Bluestone Optionholders in the United States should also be aware that other requirements under Canadian laws may differ from those required under U.S. corporate laws and U.S. Securities Laws. The enforcement by Bluestone Shareholders and Bluestone Optionholders of rights, claims and civil liabilities under U.S. Securities Laws may be affected adversely by the fact that the Company and Bluestone are organized under the laws of a jurisdiction other than the United States, that their officers and directors include residents of countries other than the United States, that some or all of the experts named in this Circular and the documents incorporated by reference may be residents of countries other than the United States, and that all or substantial portions of the assets of the Company, Aura, and such other Persons (as defined herein) are, or will be, located outside the United States. As a result, it may be difficult to or impossible for Bluestone Shareholders and Bluestone Optionholders in the United States to effect service of process within the United States predicated upon civil liabilities under U.S. Securities Laws. In addition, the courts of Canada may not (a) enforce judgments of United States courts obtained in actions against such Persons predicated upon civil liabilities under the U.S. Securities Laws or (b) enforce, in original actions, liabilities against such Persons predicated upon civil liabilities under U.S. Securities Laws.


2024 Special Meeting of Securityholders

The Aura Shares and CVRs issuable in exchange for Bluestone Shares pursuant to the Arrangement have not been registered under the U.S. Securities Act or applicable state securities laws, and are being issued in reliance on the exemption from the registration requirements of the U.S. Securities Act set forth in Section 3(a)(10) thereof on the basis of the approval of the Court, and similar exemptions from registration under applicable state securities laws. Section 3(a)(10) of the U.S. Securities Act exempts from the general registration requirements under the U.S. Securities Act, the issuance of any securities issued in exchange for one or more bona fide outstanding securities from the general requirement of registration where the terms and conditions of the issuance and exchange of such securities have been approved by a court of competent jurisdiction that is expressly authorized by law to grant such approval, after a hearing upon the substantive and procedural fairness of the terms and conditions of such issuance and exchange at which all persons to whom it is proposed to issue the securities have the right to appear and receive timely and adequate notice thereof. The Court is authorized to conduct a hearing at which the substantive and procedural fairness of the terms and conditions of the Arrangement will be considered. The Court issued the Interim Order on November 18, 2024 and, subject to the approval of the Arrangement by the Bluestone Shareholders and Bluestone Optionholders, a hearing of the application for the Final Order is currently scheduled to take place on January 6, 2025 at the Court at 800 Smithe Street, Vancouver, British Columbia, at 10:00 a.m. (Vancouver time), or as soon thereafter as counsel may be heard, or at any other date and time and by any other method as the Court may direct. All Bluestone Shareholders and Bluestone Optionholders are entitled to appear and be heard at this hearing. The Final Order will constitute a basis for the exemption from the registration requirements of the U.S. Securities Act provided by Section 3(a)(10) thereof with respect to the Aura Shares and CVRs issued to the Bluestone Shareholders in exchange for their Bluestone Shares pursuant to the Arrangement. Prior to the hearing on the Final Order, the Court will be informed of this effect of the Final Order.

This Arrangement and the Aura Shares and CVRs to be issued in connection with the Arrangement have not been approved or disapproved by the SEC or any other securities regulatory authority, nor has the SEC or any securities regulatory authority passed upon the fairness or the merits of this transaction or upon the accuracy or adequacy of the information contained in this Circular.

Bluestone Shareholders and Bluestone Optionholders in the United States should be aware that the disposition by them of their Bluestone Shares and, if applicable, Bluestone Options, as described herein, may have tax consequences both in the United States and in Canada. Such consequences for Bluestone Shareholders and Bluestone Optionholders may not be described fully herein. For a general discussion of certain material Canadian federal income tax considerations, see "Certain Canadian Federal Income Tax Considerations". Bluestone Shareholders and Bluestone Optionholders in the United States are advised to see "Certain U.S. Federal Income Tax Consequences of the Arrangement" for a general discussion of certain United States federal income tax considerations, and to consult their own tax advisors regarding the relevant federal, state, local and foreign tax consequences to them of participating in the Arrangement.


2024 Special Meeting of Securityholders

Bluestone Shareholders and Bluestone Optionholders in the United States should be aware that the annual and quarterly financial statements and financial information of the Company are prepared in accordance with IFRS Accounting Standards as issued by the International Accounting Standards Board and are subject to Canadian auditing and auditor independence standards, each of which differ in certain material respects from United States generally accepted accounting principles and auditing and auditor independence standards and thus may not be comparable in all respects to financial statements and information of United States companies.

Bluestone Shareholders and Bluestone Optionholders in the United States should be aware that the scientific and technical information included or incorporated by reference herein, including any estimates of mineral resources and mineral reserves, has been prepared in accordance with NI 43-101, which differs from Subpart 1300 of Regulation S-K as adopted by the SEC. Accordingly, such information may differ from the information that would be provided by a U.S. company in accordance with SEC standards.

Forward-Looking Statements

This Circular contains forward-looking statements and forward-looking information within the meaning of applicable Securities Laws and which are based on the currently available competitive, financial and economic data and operating plans of management of the Company as of the date hereof unless otherwise stated.

More particularly and without limitation, this Circular contains forward-looking statements and information concerning: the Arrangement and the completion thereof; covenants of Bluestone and Aura in relation to the Arrangement; the timing for the implementation of the Arrangement, including the expected Effective Date of the Arrangement; the anticipated benefits of the Arrangement; the principal steps of the Arrangement; the receipt of the necessary securityholder and regulatory approvals; the anticipated tax treatment of the Arrangement for Bluestone Shareholders and Bluestone Optionholders; the Rights Indenture; covenants of Aura in relation to the Rights Indenture; statements made in, and based upon, the Bluestone Fairness Opinion (as defined herein); statements relating to the business of Aura, Bluestone and the Combined Company (as defined herein) after the date of this Circular and prior to, and after, the Effective Time; achieving commercial production at the Cerro Blanco Project and the conversion and exchange of CVRs for cash following such an event if the CVR Payment Conditions (as defined herein) are is satisfied prior to the CVR Termination Date; the advancement of exploration to development of the Cerro Blanco Project; the benefits to the Cerro Blanco Project's local communities; the impact of the Arrangement on employees and local stakeholders; the strengths, characteristics, market position, and future financial or operating performance and potential of the Combined Company; the amounts received by the directors and senior officers of Bluestone under the Arrangement; de-listing of the Bluestone Shares from the TSXV; ceasing of reporting issuer status of Bluestone; the liquidity of Aura Shares and CVRs following the Effective Time; the market price of Aura Shares; Aura's ability to raise additional financing and the timing, amount and terms thereof; anticipated developments in the operations of Bluestone and Aura; expectations regarding the growth of Aura and the Combined Company; the business prospects and opportunities of Bluestone, Aura and the Combined Company; estimates of mineral resources and mineral reserves; the future demand for and prices of commodities; the future size and growth of metals markets; the timing and amount of estimated future production of Bluestone, Aura and the Combined Company; expectations regarding costs of production and capital and operating expenditures; estimates of the mine life of mineral projects; expectations regarding the costs and timing of exploration and development, and the success of such activities; sales expectations; the timing and possible outcome of pending litigation in future periods; the timing and possible outcome of regulatory and permitted matters; goals; strategies; future growth; planned future acquisitions (other than the Arrangement); the adequacy of financial resources; and other events or conditions that may occur in the future or future plans, projects, objectives, estimates and forecasts, and the timing related thereto.

In respect of the forward-looking statements and information in this Circular, the Company has provided such forward-looking statements and information in reliance on certain assumptions that it believes are reasonable at this time, including assumptions as to the ability of the Parties (as defined herein) to receive, in a timely manner and on satisfactory terms, the necessary regulatory, Court, securityholder and other third party approvals; the listing of the Aura Shares to be issued in connection with the Arrangement on the TSX; no material adverse change in the market price of gold and silver and other metal prices; the ability of the Parties to satisfy, in a timely manner, the other conditions to the closing of the Arrangement; the Company's and Aura's ability to obtain all necessary permits, licenses and regulatory approvals for operations in a timely manner; the adequacy of the financial resources of the Company and Aura; sustained labor stability and availability of equipment; the maintenance of positive relations with local groups; favorable equity and debt capital markets; stability in financial capital markets and other expectations and assumptions which management believes are appropriate and reasonable. The anticipated dates provided in this Circular regarding the Arrangement may change for a number of reasons, including the inability to secure the necessary regulatory, Court, securityholder or other third-party approvals in the time assumed or the need for additional time to satisfy the other conditions to the completion of the Arrangement. Accordingly, readers should not place undue reliance on the forward-looking statements and information contained in this Circular.


2024 Special Meeting of Securityholders

Since forward-looking statements and information address future events and conditions, by their very nature they involve inherent risks and uncertainties. Actual results could differ materially from those currently anticipated due to a number of factors and risks. Such risks, uncertainties and factors include, among others: the risk that the Arrangement may not close when planned or at all or on the terms and conditions set forth in the Arrangement Agreement; the failure of the Company and Aura to obtain the necessary regulatory, Court, securityholder and other third-party approvals, or to otherwise satisfy the conditions to the completion of the Arrangement, in a timely manner, or at all, may result in the Arrangement not being completed on the proposed terms, or at all; if a third party makes a Superior Proposal (as defined herein), the Arrangement may not be completed and the Company may be required to pay the Termination Fee (as defined herein); if the Arrangement is not completed, and the Company continues as an independent entity, there are risks that the announcement of the Arrangement and the dedication of substantial resources of the Company to the completion of Arrangement could have an impact on the Company's current business relationships and could have a material adverse effect on the current and future operations, financial condition and prospects of the Company; the failure of the Company to comply with the terms of the Arrangement Agreement may, in certain circumstances, result in the Company being required to pay the Termination Fee to Aura, the result of which could have a material adverse effect on the Company's financial position and results of operations and its ability to fund growth prospects and current operations; the benefits expected from the Arrangement may not be realized; risks associated with business integration; risks related to the Parties' respective properties; risks related to competitive conditions; risks associated with the Parties' lack of control over mining conditions; risks related to the operations of the Parties; the risk that actual results of current exploration activities may be different than forecasts; risks related to reclamation activities; the risk that project parameters may change as plans continue to be refined; risks related to changes in laws, regulations and government practices; risks associated with the uncertainty of future prices of gold and silver and other metals and currency exchange rates; the risk that plant, equipment or processes may fail to operate as anticipated; risks related to accidents and labour disputes and other risks inherent to the mining and mineral exploration industry; risks associated with delays in obtaining governmental approvals or financing or in the completion of exploration or development activities; risks related to the inherent uncertainty of mineral resource and mineral reserve estimates; risks associated with uncertainties inherent to feasibility and other economic studies; health, safety and environmental risks; and the risks discussed under the heading "Risks Related to the Arrangement".

Bluestone Shareholders and Bluestone Optionholders are cautioned that the foregoing list of factors is not exhaustive. Additional information on other factors that could affect the operations or financial results of the Parties is included in reports filed by the Company with the securities commissions or similar authorities in Canada (which are available under the Company's SEDAR+ profile at www.sedarplus.ca).

The forward-looking statements and information contained in this Circular are made as of the date hereof and the Company and Aura undertake no obligation to update publicly or revise any forward-looking statements or information, whether as a result of new information, future events or otherwise, unless required by applicable Securities Laws.

Recommendation of the Board

Recommendation of the Board and the Special Committee

The Special Committee has advised the Board that, after careful consideration of such matters as it considered relevant, as more fully described under the heading "The Arrangement - Reasons for the Arrangement", including, among other things, (i) the terms and conditions of the Arrangement Agreement; (ii) the benefits and risks associated with the Arrangement; (iii) other strategic alternatives and options available to the Company; (iv) its evaluation of the Arrangement with management and the Special Committee's legal and financial advisors, including receipt of the Bluestone Fairness Opinion and (v) the impact of the Arrangement on other stakeholders of the Company, the Special Committee has unanimously determined that the Arrangement is in the best interests of Bluestone and is fair from a financial point of view to Bluestone Shareholders, and has unanimously recommended to the Board that it authorize and approve Bluestone entering into the Arrangement Agreement and the performance of its obligations thereunder and recommend to the Bluestone Shareholders and the Bluestone Optionholders that they vote in favour of the Arrangement Resolution.



2024 Special Meeting of Securityholders


The Board, after careful consideration of such matters as it considered relevant, as more fully described under the heading "The Arrangement - Reasons for the Arrangement", including, among other things, a thorough review of the Arrangement Agreement, and taking into account the best interests of Bluestone, and after evaluating the Arrangement with management and Bluestone's legal and financial advisors, including receipt of the Bluestone Fairness Opinion, and upon the unanimous recommendation of the Special Committee, the Board has unanimously determined the Arrangement is in the best interests of Bluestone and is fair from a financial point of view to Bluestone Shareholders and that it is advisable and in the best interests of Bluestone to approve the entering into and execution and delivery of the Arrangement Agreement and the performance of its obligations thereunder, and has unanimously approved the Arrangement. Accordingly, the Board unanimously recommends that the Bluestone Shareholders and Bluestone Optionholders vote FOR the Arrangement.

See "The Arrangement - Background to the Arrangement" in this Circular.


 

Background to the Arrangement

The Arrangement Agreement is the result of arm's length negotiations among representatives of Bluestone (under the direction of the Special Committee) and Aura and their respective legal advisors, as more fully described herein. A summary of the material events, meetings, negotiations and discussions between representatives of Bluestone and Aura that preceded the execution and public announcement of the Arrangement Agreement on October 28, 2024 is included in this Circular under the heading "The Arrangement - Background to the Arrangement".


 
Reasons for the Arrangement

In the course of their evaluation, the Board carefully considered a variety of factors with respect to the Arrangement including, among others, the following:

Compelling Value - The total value of the Consideration to be received by Bluestone Shareholders pursuant to the Arrangement Agreement, assuming the Consideration is paid in full, represents a premium to the trading value of the Bluestone Shares of approximately 51% premium to the Company's spot share price and approximately 40% premium to the 25-day volume weighted average trading price of the Bluestone Shares as at October 24, 2024.

Strategic Review - The Arrangement is the result of a robust strategic review process carried out by management of the Company and overseen by the Board until formation of the Special Committee, at which time the Special Committee assumed primary oversight of the process. The process was conducted over a period of more than 12 months. The Consideration under the Arrangement represents the highest price attained for a sale of the Company as a result of this strategic review process. As part of its work in providing the Bluestone Fairness Opinion, the Bluestone Financial Advisors assessed the strategic review process which was run by management of the Company and agreed with the decision of the Special Committee and management to accept the final proposal from Aura and enter into a period of exclusivity to mutually pursue a transaction.



2024 Special Meeting of Securityholders

 

Compelling Value Relative to Strategic Alternative - After a thorough review and after receiving legal and financial advice, including the Bluestone Fairness Opinion, it was determined that the Arrangement is more favourable to the Company than the potential value that might have resulted from the only other strategic alternative reasonably available to the Company, namely, the status quo and the Company "going it alone". In making that determination, the Special Committee considered information provided by management of the Company concerning the business, operations, property, assets, financial condition, operating results and prospects of the Company and evaluated the Arrangement in the context of current and prospective industry, economic and market conditions and trends affecting the Company. Most particularly, the Special Committee considered the ability of the Company to "go it alone" with the Cerro Blanco Project as its only asset in the face of the difficult mine development process in Guatemala and the uncertainty of the funding support via the Nemesia Debt continuing past maturity. It was determined that the Company's share price was likely to deteriorate indefinitely as further, increasingly dilutive, equity financings would be required. The Board also considered the numerous examples of public mining companies with promising projects with large gold endowments that were met with indefinite permit hurdles and/or local opposition and became orphaned, illiquid issuers.

Special Committee Oversight - The strategic review process was overseen by the Special Committee, which is comprised entirely of independent directors. The Arrangement Agreement is the result of extensive and deliberate arm's length negotiations.

Uncertainty regarding Extension of Nemesia S.à.r.l. Debt - The Special Committee considered that the facility in respect of the existing Nemesia Debt matures in March 2025 and there is uncertainty as to whether it will be extended. The Company has drawn approximately US$17 million under the Nemesia Debt. The Company has benefitted significantly from the inexpensive, readily available funding provided under the Nemesia Debt. If the Nemesia Debt is not extended, it will need to be repaid, possibly via a highly dilutive equity financing.

Cash Consideration - The Cash Consideration to be received under the Arrangement Agreement provides Bluestone Shareholders with certainty of value, immediate liquidity, and removes the risk associated with the Company remaining an independent public entity amidst an uncertain outlook for the Cerro Blanco Project.

Ownership in a Leading Americas-Focused Gold and Copper Producer - Pursuant to the Share Consideration, Bluestone Shareholders will participate in any future increases in value in the Aura Shares that might result from future growth and the potential achievement of Aura's long-term plans. Aura is a high-growth, multi-jurisdiction, gold and copper producer focused on the operation and development of gold and base metal projects in the Americas, with gold and copper projects in Brazil, Mexico, and Honduras, and future projects that are at different stages of development in Brazil and Colombia. The Aura Shares comprising the Share Consideration offer immediate liquidity, along with near- and medium-term growth, complemented by Aura's technical, operational and financial capability.

Potential Additional Consideration - The Contingent Consideration provides the Bluestone Shareholders with an opportunity to receive up to an additional $0.2120 per Bluestone Share if commercial production at the Cerro Blanco Project commences, subject to the terms of the Rights Indenture and the Arrangement Agreement.

Bluestone Fairness Opinion - The Bluestone Fairness Opinion received by the Board and the Special Committee on October 25, 2024 provided that, as of the date thereof and subject to the assumptions, limitations and qualifications contained therein, the Consideration to be received by Bluestone Shareholders pursuant to the Arrangement is fair from a financial point of view to Bluestone Shareholders. See "The Arrangement - Fairness Opinions - Bluestone Fairness Opinion" in this Circular. Securityholders are urged to read the Bluestone Fairness Opinion in its entirety. The full text of the Bluestone Fairness Opinion attached as Appendix E to this Circular.



2024 Special Meeting of Securityholders

 

Continued Exposure to the Company's Assets - Bluestone Shareholders, through the Share Consideration, will retain some exposure to the Company's assets, including the Cerro Blanco Project.

Flexibility - The Arrangement provides flexibility to the Bluestone Shareholders depending on their views on timeline for development of the Cerro Blanco Project. Bluestone Shareholders who do not wish to continue their exposure to the Cerro Blanco Project can elect to receive Cash Consideration or immediately sell the Aura Shares received as Share Consideration. For those Bluestone Shareholders that wish to continue their exposure to Cerro Blanco, they can elect to receive Share Consideration and/or use Cash Consideration to buy Aura Shares or CVRs in the open market.

Current Company Financial Needs - The Company's cash on hand is not sufficient to fund the Company's future operations. To fund those operations the Company would need to raise additional equity or debt financing or monetize assets. In the current market for equity and debt financing and given the current volatility of the capital markets, there can be no assurance that the Company will be able to raise such additional financing on reasonable terms or at all. Further, any equity financing would likely be highly dilutive to Bluestone Shareholders. The Arrangement avoids the need for the Company to complete such financing or asset transactions.

Credibility of Purchaser - Aura has demonstrated commitment, credit worthiness and a track record of completing similar transactions which is indicative of the ability of Aura to complete the transactions contemplated by the Arrangement Agreement. The Arrangement is not subject to a financing condition.

Limited Conditionality and Execution Risk - Aura's obligation to complete the Arrangement is subject to a limited number of conditions. In addition, the Special Committee considered the likelihood of receiving the required securityholder and court approvals for closing of the Arrangement in the time period set out in the Arrangement Agreement.

Securityholder Approval - The Arrangement Resolution must be approved by at least (i) 66⅔% of the votes cast by Bluestone Shareholders present or represented by proxy at the Meeting; (ii) 66⅔% of the votes cast by Bluestone Securityholders, voting together as a single class, present or represented by proxy at the Meeting; and (iii) a majority of the votes cast by Bluestone Shareholders other than votes attached to Bluestone Shares required to be excluded pursuant to MI 61-101.

Court Approval - In order to become effective, the Arrangement must be approved by the Court, which will consider, among other things, the substantive and procedural fairness and reasonableness of the Arrangement to Bluestone Securityholders.


2024 Special Meeting of Securityholders

Dissent Rights - Registered Bluestone Shareholders will be provided with the right to exercise Dissent Rights in connection with the Arrangement.

Voting Agreements - Aura has entered into voting agreements with the Bluestone Locked-Up Securityholders who collectively beneficially own or control approximately 40% of the issued and outstanding Bluestone Securities, which provide, among other things, that such Bluestone Locked-Up Securityholders will vote in favour of the Arrangement subject to the terms and conditions of the voting agreements.

Fiduciary Out - Under the Arrangement Agreement, the Board, in certain circumstances, is able to consider, accept and enter into a definitive agreement with respect to a Superior Proposal and terminate the Arrangement Agreement and the Termination Fee in those circumstances is reasonable in the circumstances and not preclusive of other offers

See "The Arrangement - Reasons for the Arrangement" in this Circular.

Proxies and Voting

Voting

Each Registered Bluestone Shareholder whose name is entered on the central securities register of the Company at the close of business on the Record Date is entitled to one vote for each Bluestone Share registered in his, her or its name. Each holder of Bluestone Options whose name is entered on the respective securities registers of the Company at the close of business on the Record Date is entitled to one vote for each such Bluestone Option held in his, her or its name, as the case may be.

In order to become effective, the Arrangement Resolution must be approved by at least (i) 66⅔% of the votes cast by Bluestone Shareholders present or represented by proxy at the Meeting; (ii) 66⅔% of the votes cast by Bluestone Securityholders, voting together as a single class, present or represented by proxy at the Meeting; and (iii) a majority of the votes cast by Bluestone Shareholders other than votes attached to Bluestone Shares required to be excluded pursuant to MI 61-101.


2024 Special Meeting of Securityholders

The manner in which you vote your Bluestone Shares depends on whether you are a Registered Bluestone Shareholder (or Bluestone Optionholder) or Beneficial Bluestone Shareholder. You are a Registered Bluestone Shareholder (or Bluestone Optionholder) if your name appears on your share (or Bluestone Option) representing Bluestone Shares (or Bluestone Options). Most Bluestone Shareholders are Beneficial Bluestone Shareholders. You are a Beneficial Bluestone Shareholder if you beneficially own Bluestone Shares that are held in the name of an Intermediary such as a bank, a trust company, a securities broker, a trustee or other nominee, and as a result do not have the Bluestone Shares registered in your own name.

Registered Bluestone Shareholder, Bluestone Optionholder and Duly Appointed Proxyholder Voting

Registered Bluestone Shareholders and Bluestone Optionholders, who are eligible to vote, can vote their Bluestone Shares, or Bluestone Options, as applicable, either:

1. in person at the Meeting; or

2. by proxy.

A Registered Bluestone Shareholder or Bluestone Optionholder who wishes to vote in person at the Meeting need not complete or return the form of proxy or voting instruction form included in this Circular, as those such holders choosing to attend the Meeting may have their votes taken and counted at the Meeting. However, to ensure your representation at the Meeting, we encourage you to return the enclosed form(s) of proxy or VIF, whether or not you plan to personally attend. Sending your form(s) of proxy or VIF will not prevent you from voting in person at the Meeting.

Voting by proxy is the easiest way for Registered Bluestone Shareholders and Bluestone Optionholders to cast their vote. To vote securities by proxy, Registered Bluestone Shareholders and Bluestone Optionholders can vote using the following methods:

 Internet Voting: You may vote over the internet by going to www.investorvote.com.

Appointment of Proxyholders

If you do not attend and vote at the Meeting, you can still make your votes count by appointing a person or company who will attend the Meeting to act as your proxyholder at the Meeting.

Bluestone Securityholders that are entitled to vote at the Meeting may by means of a proxy appoint a proxyholder or one or more alternative proxyholders, who need not be a Bluestone Shareholder, to attend and act at the Meeting for the Bluestone Securityholder on their behalf.


2024 Special Meeting of Securityholders

The individuals named in the accompanying form of proxy are directors and/or officers and/or employees of Bluestone. A Bluestone Securityholder, that is entitled to vote, wishing to appoint some other person (who need not be a Bluestone Shareholder) to represent him or her at the Meeting has the right to do so, either by inserting such person's name in the blank space provided in the form of proxy or by completing another form of proxy. Such Bluestone Securityholder should notify the nominee of his or her appointment, obtain his or her consent to act as proxy and instruct him or her on how their Bluestone Securities are to be voted. In any case, the form of proxy should be dated and executed by the Bluestone Securityholder or his/her attorney authorized in writing, or if the Bluestone Securityholder is a corporation, under its corporate seal, or by an officer or attorney thereof duly authorized.

Beneficial Bluestone Shareholders should follow the instructions provided by their Intermediary to ensure their vote is counted at the Meeting and should arrange for their intermediary to complete the necessary steps to ensure that they receive the Consideration for their Bluestone Shares as soon as possible following completion of the Arrangement. Please see "Beneficial Bluestone Shareholder Voting" for more information.

Exercise of Discretion

On a poll, the nominees named in the accompanying form of proxy will vote or withhold from voting the Bluestone Securities represented thereby in accordance with the instructions of the Bluestone Securityholder on any ballot that may be called for. If a Bluestone Securityholder specifies a choice with respect to any matter to be acted upon, such Bluestone Securityholder's Bluestone Securities will be voted accordingly. If a Bluestone Securityholder specified on the form of proxy how such Bluestone Securityholder would like their Bluestone Securities to be voted on particular matter (by marking FOR or AGAINST), then such Bluestone Securityholder's proxy holder must vote their Bluestone Securities accordingly. If a Bluestone Securityholder does not specify on the form of proxy how it, he or she would like their Bluestone Securities to be voted on a particular matter, then his or her proxyholder can vote their Bluestone Securities as he or she sees fit. Unless contrary instructions are provided, the voting rights attached to the Bluestone Shares and Bluestone Options will be voted IN FAVOUR OF the Arrangement Resolution.

The form of proxy confers discretionary authority with respect to: (i) amendments or variations to the matters of business to be considered at the Meeting; and (ii) other matters that may properly come before the Meeting. As of the date of this Circular, the management of Bluestone is not aware of any amendments, variations or other matters to come before the Meeting, other than the matters set forth in the Notice of Meeting included in this Circular. If, however, other matters properly come before the Meeting, the persons named in the form of proxy and voting instruction form will vote on them in accordance with their judgment, pursuant to the discretionary authority conferred upon them by the form of proxy with respect to such matters.

Revocation of Proxies

A Registered Bluestone Shareholder or Bluestone Optionholder who has submitted a proxy may revoke it at any time prior to the exercise thereof at the Meeting or any adjournment or postponement thereof.

In addition to revocation in any other manner permitted by law, a proxy may be revoked by:

(a) executing a proxy bearing a later date or by executing a valid notice of revocation, either of the foregoing to be executed by the Registered Bluestone Shareholder or Bluestone Optionholder or such holders' authorized attorney in writing, or, if such a holder is a corporation, under its corporate seal by an officer or duly authorized attorney, and by delivering the proxy bearing a later date to Computershare at 100 University Avenue, 8th Floor, Toronto, Ontario, M5J 2Y1 or to the address of the registered office of the Company at 2800 - 1055 Dunsmuir Street, Vancouver, BC V7X 1L2, at any time up to and including the last business day that precedes the day of the Meeting or, if the Meeting is adjourned, the last business day that precedes any reconvening thereof, or to the Chair of the Meeting on the day of the Meeting or any reconvening thereof, or in any other manner provided by law; or


2024 Special Meeting of Securityholders

(b) personally attending the Meeting and voting the Bluestone Shares and/or Bluestone Options, as applicable.

Upon such deposit, the proxy is revoked. A revocation of a proxy will not affect a matter on which a vote is taken before the revocation.

If you are a Beneficial Bluestone Shareholder, please contact your Intermediary for instructions on how to revoke your voting instructions Intermediary to discuss whether this is possible and what procedures you need to follow. The change or revocation of voting instructions by a Beneficial Bluestone Shareholder can take several days or longer to complete and, accordingly, any such action should be completed well in advance of the deadline given in the proxy or voting instruction form by the Intermediary or its service company to ensure it is effective.

Beneficial Bluestone Shareholder Voting

If you are a Beneficial Bluestone Shareholder, meaning your Bluestone Shares are not registered in your own name, they will be held in the name of a "nominee", usually a bank, trust company, securities dealer, other financial institution or intermediary, or depository, such as CDS & Co., of which an intermediary was a participant and, as such, your nominee will be the entity legally entitled to vote your Bluestone Shares and must seek your instructions as to how to vote your Bluestone Shares.

If you are a Beneficial Bluestone Shareholder, your Intermediary will send you a VIF or, less frequently, a proxy form with this Circular. This form will instruct the Intermediary as to how to vote your Bluestone Shares at the Meeting on your behalf. You must follow the instructions from your Intermediary to vote.

There are two kinds of Beneficial Bluestone Shareholders: (i) those who object to their name being made known to the issuers of securities which they own, known as objecting beneficial owners ("OBOs"); and (ii) those who do not object to their name being made known to the issuers of securities which they own, known as non-objecting beneficial owners ("NOBOs").

Intermediaries are required to forward the Meeting materials to Beneficial Bluestone Shareholders unless in the case of certain proxy-related materials the Beneficial Bluestone Shareholder has waived the right to receive them. The majority of Intermediaries now delegate responsibility for obtaining instructions from beneficial shareholders to Broadridge. Broadridge typically mails a VIF to Beneficial Bluestone Shareholders and asks Beneficial Bluestone Shareholders to return the VIF to Broadridge. The Company may utilize Broadridgeʼs QuickVote™ system to assist NOBOs with voting their Bluestone Shares over the telephone.

For greater certainty, Beneficial Bluestone Shareholders should note that they are not entitled to use a VIF or proxy form received from Broadridge or their Intermediary to vote Bluestone Shares directly at the Meeting. Instead, the Beneficial Bluestone Shareholder must complete the VIF or proxy form and return it as instructed on the form. The Beneficial Bluestone Shareholder must complete these steps well in advance of the Meeting in order to ensure such Bluestone Shares are voted.

If you are a Beneficial Bluestone Shareholder, your intermediary will have provided to you a VIF. The Company intends to reimburse intermediaries for the delivery of the meeting materials to OBOs.

In the alternative, if you wish to attend and vote at the Meeting or have another person attend and vote on your behalf, indicate your name or the name of your proxyholder, as applicable, in the VIF or proxy form, and return it as instructed by your Intermediary. You will also have to register yourself as your proxyholder, as described above in "Appointment of Proxyholders". Your Intermediary may have also provided you with the option of appointing yourself or someone else to attend and vote on your behalf at the Meeting.

THE ARRANGEMENT

Background to the Arrangement

The entering into of the Arrangement Agreement was the result of a review by Bluestone of the available strategic alternatives and seeking to maximize value to its stakeholders. The terms of the Arrangement Agreement were arrived at through extensive arm's length negotiations conducted among representatives of Bluestone and Aura, including their respective financial and legal advisors. The following is a summary of the principal events that preceded the execution of the Arrangement Agreement and the public announcement of the Arrangement on October 28, 2024.

Bluestone's management team and the Board regularly review and consider Bluestone's long-term strategic plans and objectives with the goal of enhancing shareholder value, including assessing the relative merits of continuing as an independent enterprise, business combinations or acquisitions, and other strategic opportunities.


2024 Special Meeting of Securityholders

On July 6, 2023, the Company publicly announced that it had commenced a strategic review process to explore and evaluate potential strategic alternatives to further advance the Cerro Blanco Project and the Mita Geothermal Project, including the potential sale of part or all of the assets of the Company, a sale of the Company, a merger or other business combination with another party, or other strategic transaction.

Over the following year, management ran an active and extensive sale process in which over 100 potentially interested parties were contacted. Of these parties, 9 signed confidentiality agreements and were given access to an online dataroom.

In the meantime, Bluestone continued to advance the Cerro Blanco Project and de-risk the Cerro Blanco Project by trying to obtain the environmental permit amendment from Guatemala's Ministry of Environment and Natural Resources ("MARN"). As one strategic alternative, Bluestone considered developing the Cerro Blanco Project on its own or with a partner. On January 18, 2024, the Company announced that MARN approved the environmental permit amendment for the Cerro Blanco Project to change the mining method from the existing permitted underground development to surface mining development.

In February 2024, the Company received initial indicative proposals from 3 different parties, being Party 1, Party 2 and Aura (the "Initial Parties").

Over the month of April 2024, site visits at the Cerro Blanco Project were conducted with the Initial Parties and in May 2024, the Company asked those parties to submit final non-binding proposals by June 26, 2024.

On June 17, 2024, the Company reported that MARN had notified the Company that it was challenging the approval procedure that approved the environmental permit amendment for the Cerro Blanco Project. On June 21, 2024, the Company disclosed that it was appealing the notification from MARN.

On June 19, 2024, after discussions and having considered the advice of Blakes, the Board approved the formation of the Special Committee comprised of Jill Donaldson, Martino De Ciccio and Jamie Beck (each an independent director of Bluestone). The Board also approved a broad mandate for the Special Committee that included responsibility for, among other things, reviewing, assessing and examining, and reporting to the Board on any proposals or offers to acquire all of the issued and outstanding securities of the Company, and reviewing, assessing and examining any strategic alternatives available to Bluestone that may offer greater value to Bluestone Shareholders and which may otherwise be in the best interests of the Company. In carrying out its responsibilities, the Special Committee was authorized to, among other things, retain financial and other advisors if required or considered to be appropriate in the circumstances. Blakes advised the Board on its duties as directors. The members of the Board were provided with an opportunity to ask questions and received responses from Blakes.

By June 26, 2024, the Company received non-binding proposals from the 3 different parties, including Aura (the "Initial Proposals"). The initial Aura proposal ("Initial Aura Proposal") provided for an acquisition of all of the issued and outstanding Bluestone Shares for upfront cash consideration and additional cash proceeds contingent on the occurrence of certain production milestones at the Cerro Blanco Project. The initial Party 1 proposal ("Initial Party 1 Proposal") provided for multiple alternative acquisition structures comprised of upfront and contingent consideration at a premium to Bluestone's current market price but contemplated that the exchange ratio would be re-negotiated and determined at the time of announcement. The Party 2 Proposal was less than the proposals received from Aura and Party 1.

On June 28, 2024, the Special Committee held its first meeting to consider the Initial Proposals. At this meeting, the Special Committee also selected Jill Donaldson as its chair and retained Stikeman Elliott LLP as its legal counsel. At a meeting held on July 4, 2024, Stikeman advised the Special Committee on its duties as directors. The members of the Special Committee were provided with an opportunity to ask questions and received responses from Stikeman. The Special Committee also further discussed the Initial Proposals.

The Special Committee held subsequent meetings to consider the Initial Proposals on July 12, 2024, July 19, 2024 and July 26, 2024. Management also conducted bid clarification calls between June 28, 2024 and July 12, 2024 and requested bidders to increase the consideration they had initially offered. The Special Committee ultimately instructed management to advance discussions with all three parties, including requesting that management ask all three parties to increase the consideration they were offering.


2024 Special Meeting of Securityholders

On July 12, 2024, the Special Committee determined that Party 1 was the preferred bidder, and subsequently determined at its July 19, 2024 meeting to discontinue discussions with Party 2 and focus on the proposals made by Aura and Party 1.

On July 24, 2024, Aura delivered a second unsolicited non-binding proposal ("Second Aura Proposal") to Bluestone with respect to a proposed acquisition by Aura of all of the issued and outstanding Bluestone Shares for upfront consideration consisting of: (i) cash consideration in an amount greater than the upfront cash consideration set out in the Initial Aura Proposal; and (ii) a certain amount of Aura Shares, along with additional cash proceeds contingent on the occurrence of certain production milestones at the Cerro Blanco Project, in an amount greater than the contingent cash proceeds set out in the Initial Aura Proposal, with the sum of all the consideration payable (assuming payment of all consideration) being a premium to Bluestone's current market price. The Second Aura Proposal requested that the parties enter into exclusive negotiations.

On July 25, 2024 the Special Committee met and reviewed the Second Aura Proposal and determined that the Party 1 proposal still offered Shareholders better value than the Second Aura Proposal and that Party 1 remained the preferred bidder.

On July 26, 2024 Management delivered to Party 1 a draft term sheet based on the Initial Party 1 Proposal.

On August 5, 2024, Party 1 delivered a second proposal inclusive of a revised term sheet ("Second Party 1 Proposal") that provided for an acquisition of substantially all of the assets of Bluestone at the same form of consideration of its Initial Party 1 Proposal and conditional on the parties entering into exclusive negotiations. The Second Party 1 Proposal continued to require that the parties would re-negotiate the exchange ratio at the time of the announcement.

On August 15, 2024, management of Bluestone and Party 1 met to discuss the Second Party 1 Proposal. Party 1 would not commit to a fixed exchange ratio or to update pricing based on current share prices and negotiations were suspended.

On September 1, 2024, Aura delivered a third non-binding proposal ("Third Aura Proposal") to Bluestone with respect to a proposed acquisition by Aura of all of the issued and outstanding Bluestone Shares for a higher value than the Second Aura Proposal, with increased upfront cash and Aura Share consideration and less contingent cash consideration when compared to the Second Aura Proposal. Assuming payment of all consideration, the Third Aura Proposal was also a premium to Bluestone's current market price. The Third Aura Proposal requested that the parties enter into exclusive negotiations.

On September 3, 2024, the Special Committee met to consider the Third Aura Proposal. The members of the Special Committee were provided with an opportunity to ask questions and received responses from Stikeman. The Special Committee discussed various alternatives that the Company could take in response to receipt of the Third Aura Proposal. This discussion included: (a) a comparison between the consideration offered in the Third Aura Proposal and the estimated value of the Company based on a number of different financial metrics; (b) the likelihood of increasing the consideration with further negotiation; (c) the likelihood of alternative proposals from other parties (including Party 1) including which potential alternative would be in the best interests of the Company and the risks and opportunities associated with each potential alternative; and (d) the timing of the Third Aura Proposal and the merits of entering into exclusivity. The Special Committee reviewed and evaluated the Third Aura Proposal, considered comparisons to precedent transactions and a comparison to the Company's standalone prospects. The Special Committee authorized management to enter into exclusive negotiations with Aura but to reduce the proposed exclusivity period.

On September 6, 2024, Aura and Bluestone entered into a non-binding letter of intent and exclusivity agreement with respect to the Third Aura Proposal.

On September 11, 2024, Aura's legal counsel was provided with access to Bluestone's dataroom. Bluestone continued with its technical, financial, and legal due diligence of Aura.


2024 Special Meeting of Securityholders

On September 26, 2024, Aura delivered a draft arrangement agreement to Bluestone.

During the remainder of September and over the course of October 2024, Bluestone and Aura negotiated the definitive documents extensively and the Special Committee met on numerous occasions to discuss the merits of the proposed transaction with Aura.

After receiving the draft Arrangement Agreement on September 26, 2024, the Special Committee met to discuss certain key issues relating to the Arrangement and Aura's portfolio of assets, and to receive an update on due diligence on the Aura assets. The Special Committee also received an overview of the status of the transaction and provided instructions on certain aspects of the draft Arrangement Agreement to Blakes.

On October 8, 2024, Bluestone management toured and reviewed the technical and financial aspects of Aura's San Andres mine operation in Honduras.

On October 10, 2024, Bluestone delivered a revised draft of the Arrangement Agreement to Aura.

On October 10, 2024, the Special Committee retained GenCap as its financial advisor and to provide a fixed fee fairness opinion in connection with a potential change of control transaction.

On October 15, 2024, Aura delivered a revised draft of the Arrangement Agreement to Bluestone.

On October 18, 2024, Bluestone delivered a revised draft of the Arrangement Agreement to Aura.

On October 22nd and 23rd, 2024, Bluestone and Aura management met in person in Mexico to discuss various outstanding commercial points on the proposed Transaction and to tour and review the technical and financial aspects of the Aranzazu mine operation.

In the afternoon of October 24, 2024 and in the morning of October 25, 2024, Aura and Bluestone, and their respective legal counsel, met to discuss certain outstanding points on the Arrangement Agreement.

On October 25, 2024, the Special Committee and Stikeman met with GenCap during which GenCap provided its oral opinion, which was subsequently confirmed by delivery of a written opinion, that, as of October 25, 2024, and subject to the assumptions, limitations, and qualifications set out therein, the Consideration is fair, from a financial point of view, to the Bluestone Shareholders. After discussion and consideration, including a review of the terms and conditions of the proposed transaction and, in particular, the ability to respond to Superior Proposals, the benefits and risks associated with the Arrangement, the business and future prospects of Bluestone, the expected timing, the risks associated with the Arrangement, the Bluestone Fairness Opinion and other relevant matters, the Special Committee unanimously determined that the Arrangement is fair to the Bluestone Shareholders and the Arrangement and the entering into of the Arrangement Agreement are in the best interests of Bluestone. Following this meeting, the Special Committee met with the full Board and Bluestone's senior management, together with representatives of Blakes, Stikeman and GenCap. At this meeting, the Special Committee unanimously recommended to the Board that the Board approve the Arrangement and the entering into of the Arrangement Agreement and ancillary agreements, and recommend that Bluestone Securityholders vote in favour of the Arrangement.

Following the receipt of the report of the Special Committee, Blakes reviewed with the Board the terms of the Arrangement Agreement and ancillary agreements to be entered into in connection with the Arrangement, and the Board was provided with the opportunity to ask questions of Bluestone's senior management and of its legal and financial advisor. After a discussion and taking into consideration the unanimous recommendation of the Special Committee, its own assessment of the proposed transaction and the interests of Bluestone and the Bluestone Shareholders, the Bluestone Fairness Opinion and other relevant matters, the Board unanimously determined that the Consideration is fair to the Bluestone Shareholders and the Arrangement and the entering into of the Arrangement Agreement are in the best interests of Bluestone. The Board unanimously approved entering into the Arrangement Agreement and the ancillary agreements and resolved to recommend that Bluestone Securityholders vote in favour of the Arrangement. Bluestone and Aura executed the Arrangement Agreement late in the evening of October 25, 2024, effective as of October 25, 2024, and jointly announced the Arrangement prior to the open of the market on October 28, 2024.


2024 Special Meeting of Securityholders

Reasons for the Arrangement

In evaluating and unanimously approving the Arrangement, the Special Committee and the Board gave careful consideration to the current position and condition and the expected and potential future position and condition of the business of the Company, and all terms of the Arrangement Agreement, including the conditions precedent, representations and warranties and deal protection provisions. The Special Committee and the Board considered a number of factors including, among others, the following:

 Compelling Value - The total value of the Consideration to be received by Bluestone Shareholders pursuant to the Arrangement Agreement represents, assuming the Consideration is paid in full, a premium to the trading value of the Bluestone Shares of approximately 51% premium to the Company's spot share price and approximately 40% premium to the 25-day volume weighted average trading price of the Bluestone Shares as at October 24, 2024.

 Strategic Review - The Arrangement is the result of a robust strategic review process carried out by management of the Company and overseen by the Board until formation of the Special Committee, at which time the Special Committee assumed primary oversight of the process. The process was conducted over a period of more than 12 months. The Consideration under the Arrangement represents the highest price attained for a sale of the Company as a result of this strategic review process. As part of its work in providing the Bluestone Fairness Opinion, the Bluestone Financial Advisors assessed the strategic review process which was run by management of the Company and agreed with the decision of the Special Committee and management to accept the final proposal from Aura and enter into a period of exclusivity to mutually pursue a transaction.

 Compelling Value Relative to Strategic Alternative - After a thorough review and after receiving legal and financial advice, including the Bluestone Fairness Opinion, it was determined that the Arrangement is more favourable to the Company than the potential value that might have resulted from the only other strategic alternative reasonably available to the Company, namely, the status quo and the Company "going it alone". In making that determination, the Special Committee considered information provided by management of the Company concerning the business, operations, property, assets, financial condition, operating results and prospects of the Company and evaluated the Arrangement in the context of current and prospective industry, economic and market conditions and trends affecting the Company. Most particularly, the Special Committee considered the ability of the Company to "go it alone" with the Cerro Blanco Project as its only asset in the face of the difficult mine development process in Guatemala and the uncertainty of the funding support via the Nemesia Debt continuing past maturity. It was determined that the Company's share price was likely to deteriorate indefinitely as further, increasingly dilutive, equity financings would be required. The Board also considered the numerous examples of public mining companies with promising projects with large gold endowments that were met with indefinite permit hurdles and/or local opposition and became orphaned, illiquid issuers.

 Special Committee Oversight - The strategic review process was overseen by the Special Committee, which is comprised entirely of independent directors. The Arrangement Agreement is the result of extensive and deliberate arm's length negotiations.

 Uncertainty regarding Extension of Nemesia S.à.r.l. Debt - The Special Committee considered that the facility in respect of the existing Nemesia Debt matures in March 2025 and there is uncertainty as to whether it will be extended. The Company has drawn approximately US$17 million under the Nemesia Debt. The Company has benefitted significantly from the inexpensive, readily available funding provided under the Nemesia Debt. If the Nemesia Debt is not extended, it will need to be repaid, possibly via a highly dilutive equity financing.


2024 Special Meeting of Securityholders

 Cash Consideration - The Cash Consideration to be received under the Arrangement Agreement provides Bluestone Shareholders with certainty of value, immediate liquidity, and removes the risk associated with the Company remaining an independent public entity amidst an uncertain outlook for the Cerro Blanco Project.

 Ownership in a Leading Americas-Focused Gold and Copper Producer - Pursuant to the Share Consideration, Bluestone Shareholders will participate in any future increases in value in the Aura Shares that might result from future growth and the potential achievement of Aura's long-term plans. Aura is a high-growth, multi-jurisdiction, gold and copper producer focused on the operation and development of gold and base metal projects in the Americas, with gold and copper projects in Brazil, Mexico, and Honduras, and future projects that are at different stages of development in Brazil and Colombia. The Aura Shares comprising the Share Consideration offer immediate liquidity, along with near- and medium-term growth, complemented by Aura's technical, operational and financial capability.

 Potential Additional Consideration - The Contingent Consideration provides the Bluestone Shareholders with an opportunity to receive up to an additional $0.2120 per Bluestone Share if commercial production at the Cerro Blanco Project commences, subject to the terms of Rights Indenture and the Arrangement Agreement.

 Bluestone Fairness Opinion - The Bluestone Fairness Opinion received by the Board and the Special Committee on October 25, 2024 provided that, as of the date thereof and subject to the assumptions, limitations and qualifications contained therein, the Consideration to be received by Bluestone Shareholders pursuant to the Arrangement is fair from a financial point of view to Bluestone Shareholders. See "The Arrangement - Fairness Opinions - Bluestone Fairness Opinion" in this Circular. Securityholders are urged to read the Bluestone Fairness Opinion in its entirety. The full text of the Bluestone Fairness Opinion attached as Appendix E to this Circular.

 Continued Exposure to the Company's Assets - Bluestone Shareholders, through the Share Consideration, will retain some exposure to the Company's assets, including the Cerro Blanco Project.

 Flexibility - The Arrangement provides flexibility to the Bluestone Shareholders depending on their views on timeline for development of the Cerro Blanco Project. Bluestone Shareholders who do not wish to continue their exposure to the Cerro Blanco Project can elect to receive Cash Consideration or immediately sell the Aura Shares received as Share Consideration. For those Bluestone Shareholders that wish to continue their exposure to Cerro Blanco, they can elect to receive Share Consideration and/or use Cash Consideration to buy Aura Shares or CVRs in the open market.

 Current Company Financial Needs - The Company's cash on hand is not sufficient to fund the Company's future operations. To fund those operations the Company would need to raise additional equity or debt financing or monetize assets. In the current market for equity and debt financing and given the current volatility of the capital markets, there can be no assurance that the Company will be able to raise such additional financing on reasonable terms or at all. Further, any equity financing would likely be highly dilutive to Bluestone Shareholders. The Arrangement avoids the need for the Company to complete such financing or asset transactions.

 Credibility of Purchaser - Aura has demonstrated commitment, credit worthiness and a track record of completing similar transactions which is indicative of the ability of Aura to complete the transactions contemplated by the Arrangement Agreement. The Arrangement is not subject to a financing condition.

 Limited Conditionality and Execution Risk - Aura's obligation to complete the Arrangement is subject to a limited number of conditions. In addition, the Special Committee considered the likelihood of receiving the required securityholder and court approvals for closing of the Arrangement in the time period set out in the Arrangement Agreement.


2024 Special Meeting of Securityholders

 Securityholder Approval - The Arrangement Resolution must be approved by at least (i) 66⅔% of the votes cast by Bluestone Shareholders present or represented by proxy at the Meeting; (ii) 66⅔% of the votes cast by Bluestone Securityholders, voting together as a single class, present or represented by proxy at the Meeting; and (iii) a majority of the votes cast by Bluestone Shareholders other than votes attached to Bluestone Shares required to be excluded pursuant to MI 61-101.

 Court Approval - In order to become effective, the Arrangement must be approved by the Court, which will consider, among other things, the substantive and procedural fairness and reasonableness of the Arrangement to Bluestone Securityholders.

 Dissent Rights - Registered Bluestone Shareholders will be provided with the right to exercise dissent rights in connection with the Arrangement.

 Voting Agreements - Aura has entered into voting agreements with the Bluestone Locked-Up Securityholders who collectively beneficially own or control approximately 40% of the issued and outstanding Bluestone Securities, which provide, among other things, that such Bluestone Locked-Up Securityholders will vote in favour of the Arrangement subject to the terms and conditions of the voting agreements.

 Fiduciary Out - Under the Arrangement Agreement, the Board, in certain circumstances, is able to consider, accept and enter into a definitive agreement with respect to a Superior Proposal and terminate the Arrangement Agreement and the Termination Fee in those circumstances is reasonable in the circumstances and not preclusive of other offers.

The Special Committee and the Board also considered a variety of risks and other potentially negative factors relating to the Arrangement, including, among others:

 Aura and the Company may not integrate successfully and/or Aura may not successfully bring the Cerro Blanco Project into production, resulting in the Contingent Consideration not being paid to the Bluestone Shareholders;

 Directors and executive officers of the Company may have interests in the Arrangement that are different from those of Bluestone Shareholders generally;

 The Arrangement Agreement exposes the Company to certain contingent liabilities in connection with indemnification and other obligations under the Arrangement Agreement.

 The Arrangement Agreement restricts the Company from taking certain specified actions without consent of Aura until the Arrangement is completed.

 If the Arrangement is not approved by Bluestone Securityholders, or the Arrangement is otherwise not completed, the market price of the Bluestone Shares may decline and there can be no assurance that the Board will be able to find a party will to pay an equivalent or more attractive price than the Consideration to be paid to Bluestone Shareholders pursuant to the Arrangement.

 A substantial number of Bluestone Shareholders could exercise their right to dissent in respect of the Arrangement.

 Closing of the Arrangement may be delayed, may be completed on different terms or may not occur at all.

 The Company will incur costs even if the Arrangement is not completed and may have to pay a termination fee to Aura in certain circumstances.


2024 Special Meeting of Securityholders

Ultimately, the Special Committee concluded that, overall, the anticipated benefits of the Arrangement to the Company and the Bluestone Securityholders outweigh these risks and negative factors.

The above discussion of the information and factors considered by the Special Committee and the Board is not intended to be exhaustive, but is believed by the Special Committee and the Board to include the material factors considered by the Special Committee and the Board in their assessment of the Arrangement. In view of the wide variety of factors considered by the Special Committee and the Board in connection with their assessment of the Arrangement and the complexity of such matters, neither the Special Committee nor the Board considered it practical, and did not attempt, to quantify, rank or otherwise assign relative weights to the foregoing factors that it considered in reaching its decision. In addition, in considering the factors described above, individual members of the Special Committee and/or the Board may have given different weights to various factors and may have applied different analyses to each of the material factors considered by the Special Committee and the Board.

The Board's reasons for recommending the Arrangement include certain assumptions relating to forward-looking information and such information and assumptions are subject to various risks. This information should be read in light of the factors described under the section entitled "Forward-Looking Statements" and under the heading "Risks Related to the Arrangement".

Fairness Opinion 

Bluestone Fairness Opinion

In connection with the evaluation of the Arrangement, the Special Committee and the Board received and considered, among other things, the Bluestone Fairness Opinion.

Pursuant to an engagement letter dated October 12, 2024, the Company retained the Bluestone Financial Advisors as a financial advisor as to the fairness, from a financial point of view, of the consideration to be received by Bluestone Shareholders pursuant to a potential transaction.

On October 25, 2024, at a meeting of the Special Committee held to evaluate the proposed Arrangement, the Bluestone Financial Advisors delivered an oral opinion to the Special Committee and the Board, which was subsequently confirmed in writing. The Bluestone Fairness Opinion concluded that, as of October 25, 2024, based on the assumptions, limitations and qualifications therein, the Consideration to be received by Bluestone Shareholders pursuant to the Arrangement is fair, from a financial point of view, to the Bluestone Shareholders.

Bluestone Securityholders are urged to read the Bluestone Fairness Opinion in its entirety. The summary above is qualified in its entirety by reference to the full text of the written Bluestone Fairness Opinion, which among other things (a) describes the assumptions made, information reviewed, matters considered, qualifications, and limitations on the review undertaken by the Bluestone Financial Advisors and (b) summarizes the material financial analyses considered and certain additional factors considered by the Bluestone Financial Advisors in connection with the Bluestone Fairness Opinion, is attached as Appendix E to this Circular. The Bluestone Financial Advisors provided the Bluestone Fairness Opinion solely for the information of the members of the Special Committee and the Board (solely in their capacities as such), and the Bluestone Fairness Opinion was only one of many factors considered by the Special Committee and the Board in connection with their evaluation of the Arrangement. The Bluestone Fairness Opinion does not address any other terms, aspects or implications of the Arrangement. The Bluestone Fairness Opinion may not be relied upon by any other person or used for any other purpose. The Bluestone Financial Advisors expressed no view as to, and its opinion did not address, the underlying business decision of Bluestone to effect or enter into the Arrangement. The Bluestone Fairness Opinion is not intended to be and does not constitute a recommendation as to any election that a Bluestone Shareholder might make or how the Board, the Special Committee or any Bluestone Securityholder should vote or act on any matters relating to the proposed Arrangement, or otherwise. The Bluestone Fairness Opinion may not be reproduced, disseminated, quoted from or referred to (in whole or in part), without the prior written consent of the Bluestone Financial Advisors, which consent has been obtained for the purpose of the inclusion of the Bluestone Fairness Opinion and the summary thereof in this Circular.


2024 Special Meeting of Securityholders

Under the terms of the engagement, the Bluestone Financial Advisors received a fixed fee for rendering the Bluestone Fairness Opinion. The fee payable to the Bluestone Financial Advisors under the engagement letter is not contingent upon the conclusions reached in the Bluestone Fairness Opinion, or upon the successful completion of the Arrangement or any other transaction. In addition, Bluestone has agreed to reimburse the Bluestone Financial Advisors for all of its reasonable out-of-pocket expenses incurred in respect of its engagement and to indemnify the Bluestone Financial Advisors against certain liabilities which may arise out of its engagement.

Voting Support Agreements

The Bluestone Locked-Up Securityholders have entered into the Bluestone Voting Agreements with Aura pursuant to which they have agreed to vote in favour of the Arrangement Resolution. As of November 12, 2024, the Bluestone Locked-Up Securityholders hold (i) a total of 58,450,967 Bluestone Shares, representing approximately 38.36% of the outstanding Bluestone Shares, and (ii) a total of 8,320,759 Bluestone Options, representing approximately 59.33% of the outstanding Bluestone Options, for a total of approximately 40% of the Company's outstanding Bluestone Securities that will have voting rights at the Meeting.

The Bluestone Locked-Up Securityholders have agreed, subject to the terms of the Bluestone Voting Agreements, among other things: (i) vote any Bluestone Shares and Bluestone Options in favour of the Plan of Arrangement and any actions required in furtherance of, or that could be reasonably expected to facilitate, the Arrangement, and to oppose any proposed action by any Person that could prevent, interfere with or delay the completion of the Arrangement; (ii) to notify Aura of any acquisition by the Bluestone Locked-Up Securityholder (directly or indirectly) of any Bluestone Securities after the date of the Bluestone Voting Agreement; (iii) to immediately cease any existing solicitation, encouragement, discussions, negotiations or other activities commenced prior to the date of the Bluestone Voting Agreement (other than Aura and its subsidiaries or affiliates) conducted by Bluestone or any subsidiaries or representatives with respect to inquiry, proposal or offer that constitutes, or may reasonably be expected to constitute or lead to, an Acquisition Proposal; (iv) not to, directly or indirectly, (A) solicit, initiate, knowingly encourage or otherwise knowingly facilitate (including by way of furnishing or providing copies of, access to, or disclosure of, any confidential information, properties, facilities, books or records of Aura or any of its subsidiaries) any inquiry, proposal or offer that constitutes or may reasonably be expected to constitute or lead to an Acquisition Proposal, (B) enter into, engage in, continue or otherwise participate in any discussions or negotiations with any person (other than Aura and its subsidiaries or affiliates) in respect to any inquiry, proposal or offer that constitutes or may reasonably be expected to lead to an Acquisition Proposal, or (C) accept or enter into, or publicly propose to accept or enter into, any letter of intent, agreement in principal, agreement, arrangement or understanding related to any Acquisition Proposal; (v) will not option, sell, transfer, pledge, encumber, grant security interest in, hypothecate or otherwise convey or enter into any forward sale, repurchase agreement or other monetization transaction with respect to any of the Bluestone Shares or Bluestone Options, or any right or interest in any of the Bluestone Shares or Bluestone Options (legal or equitable) to any Person (except Aura) or agree to do the foregoing (except this item (v) will not prevent the Bluestone Locked-Up Securityholder from exercising any Bluestone Options); (vi) not to grant any proxy, power of attorney or other right to vote the Bluestone Shares or Bluestone Options, or enter into any voting agreement, voting trust, vote pooling or other agreement with respect to the right to vote, call meetings of shareholders or give consent or approval of any kind to any of the Bluestone Shares or Bluestone Options; (vii) not to exercise any statutory or other right to dissent in connection with the Arrangement; and (viii) not to take any other action of any kind, directly or indirectly, that might reasonably be regarded as likely to reduce the success of the Arrangement, or delay or interfere with the completion of the Arrangement or the ability of the Bluestone Locked-Up Securityholder to perform its obligations under the Bluestone Voting Agreement. The Bluestone Voting Agreement does not bind a Bluestone Locked-Up Securityholder in his or her capacity as a director or officer of the Company or limit or restrict a Bluestone Locked-Up Securityholder from properly fulfilling his or her fiduciary duties as a director or officer of the Company.


2024 Special Meeting of Securityholders

Each Bluestone Voting Agreement may also be terminated (a) by Aura, at any time by written notice; (b) by the Bluestone Locked-Up Securityholder by written notice if Aura takes any of the following actions, or permits any of the following actions to be taken, without prior consent of the Bluestone Locked-Up Securityholder: (i) changing the amount or form of consideration payable to the Bluestone Locked-Up Securityholder under the Plan of Arrangement, other than to increase the total consideration per Bluestone Share and/or add additional consideration; or (ii) otherwise vary the terms of the Plan of Arrangement in a manner that is adverse to Bluestone Shareholders.

The Bluestone Voting Agreement will automatically terminate at the Effective Time or upon the termination of the Arrangement Agreement.

Interests of Certain Persons in the Arrangement

In considering the Arrangement and the recommendation of the Board with respect to the Arrangement, Bluestone Securityholders should be aware that certain directors and senior officers of the Company have certain interests that are, or may be, different from, or in addition to, the interests of other Bluestone Securityholders generally, which may present them with actual or potential conflicts of interest in connection with the Arrangement. The Board is aware of these interests and considered them along with the other matters described above in "The Arrangement - Reasons for the Arrangement". These interests include those described below.

2024 Special Meeting of Securityholders

Employment Agreements

The Company has entered into employment agreements ("Employment Agreements") with the following employees of the Company which provide that, if there is a "Change of Control" (as that term is defined in the Employment Agreement) of the Company and the employee is terminated without cause or for "Good Reason" (as that term is defined in the Employment Agreement), concurrently or within the six-months of the date of the "Change of Control" the employee would be entitled to receive the following amounts and benefits:

 Peter Hemstead, President & CEO - an amount equal to (i) twenty-four months of the current annual salary; (ii) an amount equal to twenty-four months of the greater of the (A) the annual average performance bonuses, if any, actually paid since the start of employment (December 5, 2022) or (B) the current annual salary; and (iii) continuance of any benefits provided under any insured standard benefit plan for twelve months from the date of cessation, provided the employer shall be able to do so under the terms of the plan (with continuance of benefits being subject to the terms and conditions of the plan provider).

 Nevin Lau, CFO -- an amount equal to (i) twelve months of the current annual salary; (ii) an amount equal to the greater of the (A) the annual average performance bonuses, if any, actually paid since the start of employment (December 5, 2022) or (B) nine months of the current annual salary; and (iii) continuance of any benefits provided under any insured standard benefit plan for six months from the date of cessation, provided the employer shall be able to do so under the terms of the plan (with continuance of benefits being subject to the terms and conditions of the plan provider).

Insurance Indemnification of Directors and Officers of the Company

The Arrangement Agreement provides that, prior to the Effective Time, Bluestone may purchase customary "tail" policies of directors' and officers' liability, products and completed operations liability and employment practices liability insurance from a reputable and financially sound insurance carrier and containing terms and conditions no less favourable in the aggregate to the protection provided by the policies maintained by Bluestone and its subsidiaries which are in effect immediately prior to the Effective Date and providing protection in respect of claims arising from facts or events which occurred on or prior to the Effective Time and Bluestone will, and will cause its subsidiaries to, maintain such tail policies in effect without any reduction in scope or coverage for six years from the Effective Time; provided, that Bluestone and its subsidiaries shall not be required to pay any amounts in respect of such coverage prior to the Effective Time and provided further that the cost of such policies shall not exceed 300% of Bluestone's current annual aggregate premium for policies currently maintained by Bluestone or its subsidiaries.

Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions

Bluestone is a reporting issuer in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, New Brunswick, Newfoundland and Labrador, Nova Scotia and Prince Edward Island and, accordingly, is subject to MI 61-101. MI 61-101 is intended to regulate certain transactions to ensure equality of treatment among security holders, generally requiring enhanced disclosure, approval by a majority of security holders excluding interested parties and/or, in certain instances, independent valuations and approval and oversight of the transaction by a special committee of independent directors. The protections of MI 61-101 generally apply to "business combinations" (as defined in MI 61-101) that terminate the interests of security holders without their consent.


2024 Special Meeting of Securityholders

MI 61-101 provides that, in certain circumstances, where a "related party" (as defined in MI 61-101) of an issuer is entitled to receive a "collateral benefit" (as defined in MI 61-101) in connection with an arrangement transaction (such as the Arrangement), such transaction may be considered a "business combination" for the purposes of MI 61-101 and subject to minority approval requirements.

A "collateral benefit", as defined in MI 61-101, includes any benefit that a related party of Bluestone (which includes the directors and senior officers of Bluestone) is entitled to receive, directly or indirectly, as a consequence of the Arrangement, including, without limitation, an increase in salary, a lump sum payment, a payment for surrendering securities or other enhancement in benefits related to past or future services as an employee, director or consultant of Bluestone. However, such a benefit will not constitute a "collateral benefit" provided that certain conditions are satisfied.

Under MI 61-101, a benefit received by a related party of Bluestone is not considered to be a "collateral benefit" if the benefit is received solely in connection with the related party's services as an employee, director or consultant of Bluestone or an affiliated entity and (i) the benefit is not conferred for the purpose, in whole or in part, of increasing the value of the consideration paid to the related party for securities relinquished under the Arrangement, (ii) the conferring of the benefit is not, by its terms, conditional on the related party supporting the Arrangement in any manner, (iii) full particulars of the benefit are disclosed in the disclosure document for the transaction, and (iv) either (A) at the time the Arrangement was agreed to, the related party and its associated entities beneficially owned or exercised control or direction over less than 1% of the outstanding Bluestone Shares, or (B) (x) the related party discloses to an independent committee of Bluestone the amount of consideration that the related party expects it will be beneficially entitled to receive, under the terms of the Arrangement, in exchange for the Bluestone Shares beneficially owned by the related party, (y) the independent committee, acting in good faith, determines that the value of the benefit, net of any offsetting costs to the related party, is less than 5% of the value referred to in (B) (x), and (z) the independent committee's determination is disclosed in this Circular.

If a "related party" receives a "collateral benefit" in connection with the Arrangement, the Arrangement Resolution will also require "minority approval" in accordance with MI 61-101. If "minority approval" is required, the Arrangement Resolution must also be approved by a majority of the votes cast, excluding those votes beneficially owned, or over which control or direction is exercised, by the "related parties" of Bluestone who receive a "collateral benefit" in connection with the Arrangement.

Certain of the directors and senior officers of the Company hold Bluestone Options. If the Arrangement is completed, all Bluestone Options will be disposed of and surrendered in exchange for a cash payment equal to the Option Consideration, and such directors and senior officers holding Bluestone Options are entitled to the Black Scholes Amount at the Effective Time. In addition, employment agreements with certain senior officers provide that, if that senior officer's employment is terminated within a specified period of time in connection with a "change of control" of the Company, the senior officer would be entitled to receive compensation. See "The Arrangement - Interests of Certain Persons in the Arrangement". The Option Consideration and the compensation payable pursuant to the Employment Agreements may be considered to be "collateral benefits" received by the applicable directors and senior officers of the Company for the purposes of MI 61-101. See "The Arrangement - Plan of Arrangement" and "The Arrangement - Interests of Certain Persons in the Arrangement -Employment Agreements" in this Circular.

Each of Peter Hemstead and Nevin Lau, by virtue of his role as a senior officer of Bluestone, and Peter Hemstead, Jill Donaldson, James Beck, Martino De Ciccio, Dave DiCaire and Joyce Ngo, by virtue of his or her role as a director, is a "related party" of Bluestone (the "Bluestone Executives"). Following disclosure by management of the Company to the Special Committee of the number of Bluestone Securities held by the Bluestone Executives and the total consideration that they are expected to receive pursuant to the Arrangement, the Special Committee has determined that, other than Peter Hemstead, President and Chief Executive Officer and director of the Company, each Bluestone Executive beneficially owns, or exercises control or direction over, less than 1% of the outstanding Bluestone Shares (calculated in accordance with the provisions of MI 61-101). Accordingly, such directors and officers will not be considered to have received a "collateral benefit" under MI 61-101.


2024 Special Meeting of Securityholders

In the case of Peter Hemstead, director, President and Chief Executive Officer of Bluestone, the Special Committee has determined that Peter Hemstead beneficially owns or exercises control or direction over more than 1% of the Bluestone Shares (calculated in accordance with the provisions of MI 61-101) and, upon the completion of the Arrangement, will receive a change of control payment under the terms of a certain employment agreement dated November 29, 2022, (totaling approximately $1,433,461) and Mr. Hemstead's Black Scholes Amount (totalling approximately $239,164) represent a value that is greater than 5% of the value of the consideration which Mr. Hemstead will receive in connection with the Arrangement. Accordingly, the Special Committee has determined that the change of control payment and the Black Scholes Amount that Peter Hemstead will receive as a result of the completion of the Arrangement constitutes a collateral benefit under MI 61-101, and any Bluestone Shares beneficially owned, or over which control or direction is exercised, directly or indirectly, by Peter Hemstead must be excluded for purposes of determining whether minority approval of the Arrangement Resolution has been obtained. As of the Record Date, Peter Hemstead holds, or exercised control or direction over, directly or indirectly 507,100 Bluestone Shares and 3,386,900 Bluestone Options. As a result, a total of 507,100 Bluestone Shares and 3,386,900 Bluestone Options will be excluded from the "minority approval" vote conducted pursuant to MI 61-101.

To the knowledge of the directors and senior officers of Bluestone, after reasonable enquiry, there have been no prior valuations (as defined in MI 61-101) prepared in respect of Bluestone within the 24 months preceding the date of this Circular.

See "The Arrangement - Interests of Certain Persons in the Arrangement" in this Circular for detailed information regarding the benefits and other payments to be received by each of the directors and senior officers in connection with the Arrangement.

Effect and Details of the Arrangement

General

Pursuant to the Arrangement, all of the issued and outstanding Bluestone Shares (other than Bluestone Shares held by a Dissenting Shareholder who has validly exercised their Dissent Right and Bluestone Shares held by Aura, or any of its affiliates) will be transferred to Aura in exchange for one CVR and either: (a) the Cash Consideration, or (b) the Share Consideration, or a combination of both, subject to pro-ration if the aggregate number amount of Aura Shares to be received by Bluestone Shareholders that elected to receive the Share Consideration under the Arrangement exceeds the Aggregate Share Consideration.

Pursuant to the Arrangement, each Bluestone Option and outstanding as of the Effective Time (whether vested or unvested) shall be disposed of and surrendered by the Bluestone Optionholder without any act or formality on its or their part and without any liability in exchange for a cash payment from Bluestone equal to the Black Scholes Amount. At the effective time of this step, all Bluestone Options outstanding immediately prior to the Effective Time and the Bluestone Long Term Incentive Plan shall be cancelled.

If the Arrangement Resolution is passed by the Required Securityholder Approval, the Final Order is obtained, the Regulatory Approvals are obtained, every other requirement of the BCBCA relating to the Arrangement is complied with and all other conditions disclosed below under "The Arrangement Agreement -Conditions to Closing" are satisfied or waived, the Arrangement will become effective on the Effective Date.

On completion of the Arrangement, Bluestone will be a wholly-owned subsidiary of Aura.

Effects of the Arrangement on Shareholders' Rights

Bluestone Shareholders receiving Aura Shares under the Arrangement will become shareholders of Aura. Aura is a corporation existing under the BVI Business Companies Act (British Virgin Island). See Appendix I for a comparison of certain of these rights and obligations. This summary is not intended to be exhaustive and Bluestone Shareholders are encouraged to consult with their legal advisors for greater detail with respect to these differences.

(b) any Bluestone Shareholder who does not deposit with the Depositary a duly completed Letter of Transmittal prior to the Election Deadline or otherwise fails to fully comply with the requirements of item (a) above shall be deemed to have made the Cash Election for all Bluestone Shares held;

(c) any deposit of a Letter of Transmittal and the accompanying certificate(s) representing Bluestone Shares shall be made at the address of the Depositary specified in the Letter of Transmittal; and

(d) any registered Bluestone Shareholder who holds Bluestone Shares as a nominee, custodian, depositary, trustee or in any other representative capacity for beneficial owners of Bluestone Shares shall submit a separate Letter of Transmittal in accordance with the instructions of such beneficial owner for each such beneficial owner.

Pro-ration of Share Consideration

The maximum number of Aura Shares that may, in the aggregate, be issued to the Bluestone Shareholders that elect to receive the Share Consideration in consideration for their Bluestone Shares shall be equal to the Aggregate Share Consideration.

In the event the aggregate amount of Aura Shares that would otherwise be issuable to Bluestone Shareholders to those electing the Share Election pursuant to the Plan of Arrangement exceeds the Aggregate Share Consideration, then the Consideration payable for each Bluestone Share for which a Share Election has been made shall consist of: (i) one CVR; (ii) a number of Aura Shares equal to the Share Consideration multiplied by the Share Proration Factor (as defined in the Plan of Arrangement); and (iii) a cash payment equal to the Cash Consideration multiplied by an adjustment factor equal to one minus the Share Proration Factor (as defined in the Plan of Arrangement).

Source of Funds for the Arrangement

Aura has represented in the Arrangement Agreement that it has, and will have at the Effective Time, sufficient funds to pay (i) the cash portion of the aggregate Consideration to be paid pursuant to the Arrangement at the Effective Time; and (ii) the loan to Bluestone to provide funds for Bluestone to pay the consideration payable for all Bluestone Options to be cancelled pursuant to and in accordance with the Plan of Arrangement.


2024 Special Meeting of Securityholders

Exchange of Bluestone Securities

Procedure for Exchange of Bluestone Shares

The Letter of Transmittal has been sent to Registered Bluestone Shareholders with this Circular. The Letter of Transmittal contains procedural information relating to the Arrangement and should be reviewed carefully. Registered Bluestone Shareholders (other than the Dissenting Shareholders, Aura and any of its affiliates) can obtain additional copies of the Letter of Transmittal by contacting the Depositary at Computershare Investor Services Inc., 100 University Ave, 8th Floor, North Tower, Toronto, Ontario M5J 2Y1 or by phone, toll-free in North America at +1 (800) 564-6253 or international at + 1 (514) 982-7555, or by e-mail at corporateactions@computershare.com. The Letter of Transmittal is also available on the Company's SEDAR+ profile at www.sedarplus.ca. Bluestone Shareholders whose Bluestone Shares are registered in the name of an Intermediary must contact their Intermediary to deposit their Deposited Securities.

The Letter of Transmittal includes an election form that sets out the procedure to be followed by depositing Bluestone Shareholders to elect to receive either (a) the Cash Consideration or (b) the Share Consideration, subject to pro-ration, in addition to one CVR, for each Bluestone Share held and provides for the deposit their Bluestone Shares under the Arrangement. If the Arrangement becomes effective, in order to receive the Consideration payable in exchange for the Deposited Shares to which the depositing Bluestone Shareholder is entitled under the Plan of Arrangement, a depositing Bluestone Shareholder must deliver the Letter of Transmittal properly completed and duly executed, together with share certificate(s) or DRS Advice(s) representing its Deposited Shares and all other required documents to the Depositary pursuant to the instructions set forth in the Letter of Transmittal. An election for Cash Consideration or Share Consideration MUST be made by the Election Deadline. IF THE DEPOSITARY DOES NOT RECEIVE THE REQUIRED DOCUMENTATION OR THE BLUESTONE SHAREHOLDER FAILS TO MAKE A PROPER ELECTION BY THE ELECTION DEADLINE (OR ANY EXTENSION THEREOF), SUCH HOLDERS WILL BE DEEMED TO HAVE ELECTED TO RECEIVE THE CASH CONSIDERATION IN RESPECT OF EACH BLUESTONE SHARE HELD BY SUCH BLUESTONE SHAREHOLDER.

On the Effective Date, each Bluestone Shareholder (other than a Dissenting Shareholder, Aura and any of its affiliates) who has surrendered to the Depositary, certificates(s) or DRS Advice(s) representing one or more outstanding Bluestone Shares and made a valid election in accordance with the provisions of the Plan of Arrangement and the instructions in the Letter of Transmittal will, be entitled to receive, and the Depositary will delivery to such Bluestone Shareholder as soon as practical after following the Effective Time, a Rights Certificate representing the applicable number of CVRs, certificate(s) or DRS Advice(s), as applicable, representing the applicable number of Aura Shares comprising the Share Consideration and/or a cheque representing the applicable amount of Cash Consideration that such Bluestone Shareholder is entitled to receive in accordance with the terms of the Arrangement. The Consideration will be registered in or made payable to such name or names as directed in the Letter of Transmittal and will be either (i) sent to the address or addresses as such Bluestone Shareholder directed in their Letter of Transmittal or (ii) made available for pick up at the offices of the Depositary in accordance with the instructions of the former Bluestone Shareholder in the Letter of Transmittal.

The determination of the Depositary as to whether elections have been properly made and when elections were received by it will be binding.

If the Arrangement is not completed, the Letter of Transmittal will be of no effect and the Depositary will return all share certificates or DRS Advices representing the Deposited Shares to the holders thereof as soon as practicable at the address specified in the Letter of Transmittal.

Depositing Bluestone Shareholders are encouraged to deliver a properly completed and duly executed Letter of Transmittal together with the relevant share certificate(s) and DRS Advice(s) representing the Deposited Shares and any other required documents to the Depositary as soon as possible.

None of Bluestone, Aura or the Depositary are liable for failure to notify Bluestone Shareholders who make a deficient deposit with the Depositary.


2024 Special Meeting of Securityholders

Aura, acting reasonably, reserves the right to instruct the Depositary to waive or not to waive any and all defects or irregularities contained in any Letter of Transmittal or other document and any such waiver or non-waiver will be binding upon the affected Bluestone Shareholders. The granting of a waiver to one or more Bluestone Shareholders does not constitute a waiver for any other Bluestone Shareholders. Aura reserves the right to demand strict compliance with the terms of the Letter of Transmittal and the Arrangement. The method used to deliver the Letter of Transmittal and any accompanying share certificate(s) or DRS Advice(s) representing the Bluestone Shares is at the option and risk of the holder surrendering them, and delivery will be deemed effective only when such documents are actually received by the Depositary. The Company recommends that such certificates and documents be delivered by hand to the Depositary and a receipt therefore be obtained or that registered mail be used and appropriate insurance be obtained.

The Depositary will receive reasonable and customary compensation from Aura for its services in connection with the Arrangement, will be reimbursed for certain out-of-pocket expenses and will be indemnified against certain liabilities, including liability under securities laws and expenses in connection therewith.

The Plan of Arrangement provides that there is a maximum aggregate number of Aura Shares to be issued to Bluestone Shareholders that elected to receive the Share Consideration. If Bluestone Shareholders collectively elect to receive the Share Consideration in excess of the Aggregate Share Consideration, the Share Consideration will be subject to pro-ration. See "The Arrangement - Effects and Details of the Arrangement - Pro-ration of Share Consideration".

DRS Advices

Where Bluestone Shares are evidenced only by a DRS Advice, there is no requirement to first obtain a certificate for those Bluestone Shares or deposit with the Depositary any share certificate evidencing Bluestone Shares. Only a properly completed and duly executed Letter of Transmittal accompanied by the applicable DRS Advice(s) is required to be delivered to the Depositary in order to surrender those Bluestone Shares under the Arrangement.

Lost Share Certificates or DRS Advices

In the event any certificate which immediately prior to the Effective Time represented one or more outstanding Bluestone Shares that are ultimately entitled to Consideration pursuant to the Plan of Arrangement shall have been lost, stolen or destroyed, upon the making of an affidavit or statutory declaration of that fact by the person claiming such certificate to be lost, stolen or destroyed and who was listed immediately prior to the Effective Time as the registered holder thereof on the securities registers maintained by or on behalf of Bluestone, the Depositary will deliver in exchange for such lost, stolen or destroyed certificate, the Consideration that such holder is entitled to receive in exchange for such lost, stolen or destroyed certificate, provided the holder to whom the Consideration is to be delivered shall, as a condition precedent to the delivery, give a bond satisfactory to Aura and the Depositary (acting reasonably) in such sum as Aura and the Depositary may direct, or otherwise indemnify Aura and the Depositary in a manner satisfactory to Aura and the Depositary, acting reasonably, against any claim that may be made against Aura or the Depositary with respect to the certificate alleged to have been lost, stolen or destroyed.

If a DRS Advice representing Bluestone Shares has been lost, stolen or destroyed, the holder can request a copy of the DRS Advice by contacting Computershare by phone: toll-free in North America at +1 (800) 564-6253 or international at + 1 (514) 982-7555, with no bond indemnity required and such copy of the DRS Advice should be deposited with the Letter of Transmittal.

Extinction of Rights

To the extent a former Bluestone Shareholder shall not have surrendered Bluestone Shares to the Depositary in the manner described in this Circular on or before the Final Proscription Date, being the date that is six years after the Effective Date, then any certificates or DRS Advices, as applicable, formerly representing Bluestone Shares shall (i) cease to represent a claim by, or interest of, any former Bluestone Shareholder of Bluestone Shares of any kind or nature against or in Bluestone or Aura (or any successor to any of the foregoing) and (ii) be deemed to have been surrendered to Aura and shall be cancelled.


2024 Special Meeting of Securityholders

Any payment of consideration made by way of cheque by the Depositary pursuant to the Plan of Arrangement that has not been deposited or has been returned to the Depositary or that otherwise remains unclaimed, in each case, on or before the Final Proscription Date, and any right or claim to payment hereunder that remains outstanding on the Final Proscription Date shall cease to represent a right or claim of any kind or nature and the right of the former Bluestone Securityholder to receive the Consideration to which such holder is entitled pursuant to the Plan of Arrangement shall terminate and be deemed to be surrendered and forfeited to Aura (or any successor of Aura), for no consideration.

Fractional Consideration

Any fractional Aura Shares to be issued to a Bluestone pursuant to the Plan of Arrangement shall be rounded down to the nearest whole Aura Share. In any case where the aggregate amount of cash payable to a particular Bluestone Shareholder under the Plan of Arrangement would include a fraction of a cent, the consideration payable shall be rounded up to the nearest whole cent.

Withholding Rights

Each Party, the Depositary and their respective agents, as applicable (in this paragraph, the "payor"), shall each be entitled to deduct and withhold from any Consideration or other amount payable (whether in cash or in kind) or otherwise deliverable to any holder or former Bluestone Securityholder (including any payment to Dissenting Shareholders) such amounts as the payor is required to deduct or withhold therefrom under any applicable Law in respect of Taxes. For the purposes of the Plan of Arrangement and the Arrangement Agreement, all such deducted or withheld amounts shall be treated as having been paid to the person in respect of which such deduction or withholding was made on account of the obligation to make payment to such person thereunder, provided that such deducted or withheld amounts are actually remitted to the appropriate Governmental Entity when required by Law by, or on behalf of, the payor. Each payor is hereby authorized, subject to having received Aura's prior written consent, to sell or otherwise dispose of, on behalf of such person in respect of which a deduction or withholding was made, such portion of any Aura Shares or other security deliverable to such person as is necessary to provide sufficient funds (after deducting commissions payable, fees and other costs and expenses) to the payor to enable it to comply with such deduction or withholding requirement and the payor shall notify such person thereof and remit the applicable portion of the net proceeds of such sale to the appropriate Governmental Entity and, if applicable, any portion of such net proceeds that is not required to be so remitted shall be paid to such person. Any such sale will be made in accordance with applicable laws and at prevailing market prices, and no payor shall be under any obligation to obtain a particular price for the share or other security, as applicable, so sold. No payor will be liable for any loss arising out of such any sale.

In addition, each of Aura and the Canadian Trustee under the Rights Indenture shall be entitled to deduct and withhold from any cash amounts payable pursuant to the Rights Indenture, such amounts as Aura or the Canadian Trustee, as the case may be, is required to deduct and withhold with respect to such payment under the Tax Act. In lieu of withholding such amounts Aura and the Canadian Trustee shall be entitled to otherwise recover from or to require a holder of a CVR to provide for such applicable taxes. To the extent that amounts are so withheld, such withheld amounts shall be treated for all purposes hereof as having been paid to the relevant holder of the CVR, provided such withheld amounts are actually remitted to the appropriate taxing authority.

Securityholder Approval of the Arrangement

At the Meeting, pursuant to the Interim Order, Bluestone Securityholders will be asked to approve the Arrangement Resolution. The complete text of the Arrangement Resolution to be presented to the Meeting is set forth in Appendix A to this Circular. Each Bluestone Securityholder as at the Record Date will be entitled to vote on the Arrangement Resolution. The Arrangement Resolution must be approved by at least 66⅔% of the votes cast by Bluestone Shareholders present or represented by proxy at the Meeting; (ii) 66⅔% of the votes cast by Bluestone Securityholders, voting together as a single class, present or represented by proxy at the Meeting; and (iii) a majority of the votes cast by Bluestone Shareholders other than votes attached to Bluestone Shares required to be excluded pursuant to MI 61-101.


2024 Special Meeting of Securityholders

The Arrangement Resolution must receive the Required Securityholder Approval in order for the Company to seek the Final Order and implement the Arrangement on the Effective Date in accordance with the terms of the Final Order.

Court Approval of the Arrangement

Interim Order

The Arrangement requires approval by the Court under Section 291 of the BCBCA. Prior to the mailing of this Circular, the Company obtained the Interim Order attached as Appendix C to this Circular, providing for the calling, holding and conduct of the Meeting, the Dissent Rights, and other procedural matters.

Final Order

Subject to the terms of the Arrangement Agreement and the Interim Order, following the approval of the Arrangement Resolution by Bluestone Shareholders and Bluestone Securityholders, the Company intends to make an application to the Court for the Final Order.

The application for the Final Order is expected to take place on January 6, 2025 at the courthouse at 800 Smithe Street, Vancouver, British Columbia at 10:00 a.m. (Vancouver time) or as soon thereafter as counsel for the Company may be heard, or at any other date and time and by any other method as the Court may direct.

Any Bluestone Shareholder, Bluestone Optionholder or other interested party who wishes to participate, appear, to be represented, and to present evidence or arguments at the hearing for the Final Order must file and serve a Response to Petition in the form prescribed by the Supreme Court Civil Rules (British Columbia) together with any evidence or materials that such party intends to present to the Court, on or before 4:00 p.m. (Vancouver time) on January 6, 2025. Service of such notice shall be effected by service upon the solicitors of the Company: Blake, Cassels & Graydon LLP, Suite 3500 - 1133 Melville Street, Vancouver, British Columbia V6E 4E5, Attention: Alexandra Luchenko. In the event that the hearing is postponed, adjourned or rescheduled then, subject to further direction of the Court, only those persons having previously served a Response to Petition in compliance with the Interim Order will be given notice of the new date. Participation in the Court hearing of the application for the Final Order, including who may participate and present evidence or argument and the procedure for doing so, is subject to the terms of the Interim Order and any subsequent direction of the Court.

The Court has broad discretion under the BCBCA when making orders with respect to plans of arrangement and the Court will consider at the hearing to obtain the Final Order, among other things, the fairness and reasonableness of the Arrangement, both from a substantive and a procedural point of view. The Court may approve the Arrangement either as proposed or as amended in any manner the Court may direct, subject to compliance with such terms and conditions, if any, as the Court thinks fit. Depending upon the nature of any amendments to the Plan of Arrangement required by the Court, the Company and Aura may determine not to proceed with the Arrangement.

The Court has been advised prior to the hearing of the application for the Final Order that the Final Order, if granted, will constitute the basis for an exemption from the registration requirements of the U.S. Securities Act, pursuant to Section 3(a)(10) thereof with respect to the issuance of the Aura Shares and CVRs to be issued to Bluestone Shareholders in exchange for their Bluestone Shares pursuant to the Arrangement. Consequently, if the Final Order is granted, the issuance of the Aura Shares and CVRs to Bluestone Shareholders pursuant to the Arrangement will not require registration under the U.S. Securities Act. See "The Arrangement - Securities Law Matters - United States Securities Law Matters".

For further information regarding the Court hearing and your rights in connection with the Court hearing, see the form of the Notice of Hearing of Petition attached as Appendix D to this Circular. The Notice of Hearing of Petition constitutes notice of the Court hearing of the application for the Final Order and is your only notice of the Court hearing.


2024 Special Meeting of Securityholders

Dissenting Shareholders' Rights

The Interim Order provides that each Registered Bluestone Shareholder may exercise Dissent Rights with respect to the Arrangement. Registered Bluestone Shareholders who wish to dissent should take note that strict compliance with the Dissent Procedures is required.

The following is a summary of the provisions of the BCBCA relating to a Registered Bluestone Shareholder's Dissent Rights in respect of the Arrangement Resolution. It is not a comprehensive statement of such rights and procedures and is qualified in its entirety by the reference to the full text of Division 2 of Part 8 of the BCBCA (which is attached as Appendix H to this Circular), as modified by the Plan of Arrangement, the Interim Order (which are attached as Appendix B and Appendix C to this Circular, respectively) and any other order of the Court. The Court hearing the application for the Final Order has the discretion to alter the Dissent Rights described herein based on the evidence presented at such hearing.

The statutory provisions dealing with the right of dissent are technical and complex. Any Registered Bluestone Shareholder who intends to exercise Dissent Rights must carefully consider and comply with the provisions of Division 2 of Part 8 of the BCBCA, as modified by the Plan of Arrangement, the Interim Order and any other order of the Court and seek legal advice. Failure to comply strictly with the provisions of Division 2 of Part 8 of the BCBCA, as modified by the Plan of Arrangement, Interim Order and any other order of the Court, and to adhere to the procedures established therein, may result in the loss of the Registered Bluestone Shareholder's Dissent Rights.

Pursuant to the Interim Order, each Registered Bluestone Shareholder may exercise Dissent Rights in respect of the Arrangement under Division 2 of Part 8 of the BCBCA, as modified by the Plan of Arrangement, the Interim Order and any other order of the Court. Registered Bluestone Shareholders who duly and validly exercise such Dissent Rights and who:

 are ultimately entitled to be paid fair value for their Dissenting Shares will be deemed to have transferred their Dissenting Shares to Aura as of the Effective Time, without any further act or formality and free and clear of all liens, and shall be paid an amount equal to such fair value and will not be entitled to any other payment or consideration, including any payment that would be payable under the Arrangement had such holder not exercised their Dissent Rights in respect of such Dissenting Shares; or

 for any reason are ultimately not entitled to be paid fair value for their Dissenting Shares, will be deemed to have participated in the Arrangement on the same basis as a non-dissenting Bluestone Shareholder and will receive the Cash Consideration on the same basis as every other non-dissenting Bluestone Shareholder who is not a Bluestone Shareholder that elected to have elected to receive the Cash Consideration.

But in no case will Bluestone, Aura, the Depositary or any other person be required to recognize such persons as holding Bluestone Shares on or after the Effective Date, and the names of such Dissenting Shareholders will be deleted from the register of Bluestone as of the Effective Time. Further, in no circumstance will Bluestone, Aura, or any other person be required to recognize a person exercising Dissent Rights unless such person is a registered holder of those Bluestone Shares in respect of which such rights are sought to be exercised. For greater certainty, no Bluestone Shareholders who vote, or who have instructed a proxyholder to vote, in favour of the Arrangement Resolution will be entitled to exercise Dissent Rights.

Beneficial Bluestone Shareholders who wish to dissent with respect to their Bluestone Shares should be aware that only Registered Bluestone Shareholders are entitled to dissent with respect to them. A Registered Bluestone Shareholder such as an Intermediary who holds Bluestone Shares as nominee for Beneficial Bluestone Shareholders, some of whom wish to dissent, must exercise Dissent Rights on behalf of such Beneficial Bluestone Shareholders with respect to the Bluestone Shares held for such Beneficial Bluestone Shareholders. In such case, the Notice of Dissent (as defined below) should set forth the number of Bluestone Shares it covers.


2024 Special Meeting of Securityholders

Each Registered Bluestone Shareholder who duly and validly dissents from the Arrangement Resolution in strict compliance with Division 2 of Part 8 of the BCBCA, as modified by the Interim Order, the Plan of Arrangement and any other order of the Court will be entitled to be paid by Aura the fair value of the Bluestone Shares held by such Dissenting Bluestone Shareholder determined as at the point in time immediately before the passing of the Arrangement Resolution.

To exercise Dissent Rights, a Registered Bluestone Shareholder must dissent with respect to all Bluestone Shares in which the holder owns either a registered or beneficial interest. A Registered Bluestone Shareholder who wishes to dissent must deliver written notice of dissent (a "Notice of Dissent") to Bluestone Resources Inc., c/o Blake, Cassels & Graydon LLP, Suite 3500 - 1133 Melville Street, Vancouver, British Columbia V6E 4E5, Attention: Alexandra Luchenko by 5:00 p.m. (Vancouver time) on or before December 17, 2024 (or the Business Day that is two Business Days immediately preceding the Meeting if it is not held on December 19, 2024), and such Notice of Dissent must strictly comply with the requirements of Section 242 of the BCBCA as modified by the Plan of Arrangement, the Interim Order and any other order of the Court. Any failure by a Bluestone Shareholder to fully comply may result in the loss of that holder's Dissent Rights. Beneficial Bluestone Shareholders who wish to exercise Dissent Rights must arrange for the Registered Bluestone Shareholder holding their Bluestone Shares to deliver the Notice of Dissent.

The delivery of a Notice of Dissent does not deprive a Dissenting Bluestone Shareholder of the right to vote at the Meeting on the Arrangement Resolution; however, a Dissenting Bluestone Shareholder is not entitled to exercise the Dissent Rights with respect to any of his or her Bluestone Shares if the Dissenting Bluestone Shareholder votes in favour of the Arrangement Resolution. A vote against the Arrangement Resolution, whether in person or by proxy, does not constitute a Notice of Dissent.

A Registered Bluestone Shareholder that wishes to exercise Dissent Rights must prepare a separate Notice of Dissent for himself, herself, or itself if dissenting on his, her or its own behalf, and for each other person who beneficially owns Bluestone Shares registered in the Dissenting Shareholder's name and on whose behalf the Dissenting Shareholder is dissenting, and must dissent with respect to all of the Bluestone Shares registered in his, her or its name beneficially owned by the Beneficial Bluestone Shareholder on whose behalf he or she is dissenting. The Notice of Dissent must set out the number of Bluestone Shares in respect of which the Notice of Dissent is to be sent (the "Notice Shares") and:

 if such Notice Shares constitute all of the Bluestone Shares of which the holder is the registered and beneficial owner and the holder owns no other Bluestone Shares beneficially, a statement to that effect;

 if such Notice Shares constitute all of the Bluestone Shares of which the holder is both the registered and beneficial owner, but the holder owns additional Bluestone Shares beneficially, a statement to that effect and the names of the registered holders of Bluestone Shares, the number of Bluestone Shares held by each such holder and a statement that written notices of dissent are being or have been sent with respect to such other Bluestone Shares; or

 if the Dissent Rights are being exercised by a registered holder of Bluestone Shares who is not the beneficial owner of such Bluestone Shares, a statement to that effect and the name and address of the beneficial holder of the Bluestone Shares and a statement that the registered holder is dissenting with respect to all Bluestone Shares of the beneficial holder registered in such registered holder's name.

It is a condition to Aura's obligation to complete the Arrangement that persons holding no more than 10% of the issued and outstanding Bluestone Shares shall have validly exercised Dissent Rights (and not withdrawn such exercise). Each of the Bluestone Locked-Up Securityholders has agreed to waive his or her Dissent Rights as a holder of Bluestone Shares.

If the Arrangement Resolution is approved by the Required Securityholder Approval and if Bluestone notifies the Dissenting Shareholder of the Company's intention to act upon the Arrangement Resolution, the Dissenting Shareholder, if he, she or it wishes to proceed with the dissent, is required, within one month after Bluestone gives such notice, to send to Bluestone the certificates (if any) representing the Notice Shares and a written statement that requires Bluestone to purchase all of the Notice Shares (including a written statement prepared in accordance with Section 244(1)(c) of the BCBCA if the dissent is being exercised by a Registered Bluestone Shareholder on behalf of a Beneficial Bluestone Shareholder), whereupon, subject to the provisions of the BCBCA relating to the termination of Dissent Rights, the Bluestone Shareholder becomes a Dissenting Shareholder, and is bound to sell, and Aura is bound to purchase, those Bluestone Shares. Such Dissenting Bluestone Shareholder may not vote or exercise or assert any rights of a Bluestone Shareholder in respect of such Notice Shares, other than the rights set forth in Division 2 of Part 8 of the BCBCA, as modified by the Plan of Arrangement, the Interim Order and any other order of the Court.


2024 Special Meeting of Securityholders

The Dissenting Shareholder and Bluestone may agree on the payout value of the Notice Shares; otherwise, either party may apply to the Court to determine the fair value of the Notice Shares. There is no obligation on Bluestone or Aura to make an application to the Court. After a determination of the payout value of the Notice Shares, Aura must then promptly pay that amount to the Dissenting Shareholder. There can be no assurance that the amount a Dissenting Shareholder may receive as fair value for its Bluestone Shares will be more than or equal to the Consideration under the Arrangement. It should be noted that an investment banking opinion as to the fairness, from a financial point of view, of the consideration payable in a transaction such as the Arrangement is not an opinion as to fair value under the BCBCA.

In no circumstances will Bluestone, Aura, the Depositary or any other person be required to recognize a person as a dissenting Bluestone Shareholder unless such person is the holder of the Bluestone Shares in respect of which Dissent Rights are purported to be exercised immediately prior to the Effective Time of the Arrangement; (i) if such person has voted or instructed a proxyholder to vote the Notice Shares in favour of the Arrangement Resolution; and (ii) unless such person has strictly complied with the procedures for exercising Dissent Rights set out in Division 2 of Part 8 of the BCBCA, as modified by the Plan of Arrangement, Interim Order and Final Order, and does not withdraw such person's Notice of Dissent prior to the effective time of the Arrangement.

Dissent Rights with respect to Notice Shares will terminate and cease to apply to the Dissenting Bluestone Shareholder if, before full payment is made for the Notice Shares, the Arrangement in respect of which the Notice of Dissent was sent is abandoned or by its terms will not proceed, a court permanently enjoins or sets aside the corporate action approved by the Arrangement Resolution, the Dissenting Shareholder votes in favour of the Arrangement Resolution, or the Dissenting Shareholder withdraws the Notice of Dissent with Bluestone's written consent. If any of these events occur, Bluestone must return the share certificates representing the Bluestone Shares to the Dissenting Shareholder and the Dissenting Shareholder regains the ability to vote and exercise its rights as a Bluestone Shareholder.

If a Dissenting Bluestone Shareholder fails to strictly comply with the requirements of the Dissent Rights set out in the Interim Order, it will lose its Dissent Rights, Bluestone will return to the Dissenting Shareholder the certificates representing the Notice Shares that were delivered to Bluestone, if any, and if the Arrangement is completed, that Dissenting Shareholder will be deemed to have participated in the Arrangement on the same terms as a Bluestone Shareholder.

The discussion above is only a summary of the Dissent Rights, which are technical and complex. A Registered Bluestone Shareholder who intends to exercise Dissent Rights should carefully consider and comply with the provisions of Division 2 of Part 8 of the BCBCA, as modified by the Plan of Arrangement, Interim Order and Final Order. Persons who are beneficial holders of Bluestone Shares registered in the name of an Intermediary such as a broker, custodian, nominee, other Intermediary, or in some other name, who wish to dissent should be aware that only the registered owner of such Bluestone Shares is entitled to dissent.

Bluestone suggests that any Bluestone Shareholder wishing to avail themselves of the Dissent Rights seek their own legal advice as failure to comply strictly with the applicable provisions of the BCBCA, as modified by the Plan of Arrangement, Interim Order and any other order of the Court may result in the loss of all Dissent Rights. Dissenting Shareholders should note that the exercise of Dissent Rights can be a complex, time-consuming and expensive process.

For a general summary of certain material Canadian income tax implications to a Dissenting Shareholder, see "Certain Canadian Federal Income Tax Considerations".


2024 Special Meeting of Securityholders

Stock Exchange Delisting and Reporting Issuer Status

The Bluestone Shares will be delisted from the TSXV and the OTCQB as soon as practicable following the completion of the Arrangement. Following the Effective Date, it is expected that Aura will cause the Company to apply to cease to be a reporting issuer under the securities legislation of each of the provinces in Canada under which it is currently a reporting issuer.

Regulatory Approvals

Stock Exchange and Other Regulatory Approvals

Regulatory approvals being sought in connection with the Arrangement include the Key Consent and Approvals, in particular the ICA Clearance and the TIA Qualification. The ICA notification, in respect of the ICA Clearance, was submitted by Aura on October 29, 2024. The Rights Indenture will be qualified under the TIA by an application with the SEC on Form T-3.

Other than the Key Consent and Approvals, Bluestone is not aware of any material approval, consent or other action by any federal, provincial, state or foreign government or any administrative or regulatory agency that would be required to be obtained in order to complete the Arrangement. In the event that any such approvals or consents are determined to be required, such approvals or consents will be sought. Any such additional requirements could delay the Effective Date or prevent the completion of the Arrangement. While there can be no assurance that any regulatory consents or approvals that are determined to be required will be obtained, Bluestone currently anticipates that any such consents and approvals that are determined to be required will have been obtained or otherwise resolved by the Effective Date.

The Aura Shares are listed and posted for trading on the TSX. It is a condition of the Arrangement that the TSX shall have conditionally approved for listing the Aura Shares to be issued pursuant to the Arrangement.

Securities Law Matters

Canadian Securities Law Matters

Each Bluestone Securityholder is urged to consult such Bluestone Securityholder's professional advisors to determine the Canadian conditions and restrictions applicable to trades in Aura Shares.

The Bluestone Shares currently trade on the TSXV. After the Arrangement, Bluestone will become a wholly-owned subsidiary of Aura. It is expected that, following the completion of the Arrangement, the Bluestone Shares will be delisted from the TSXV and the OTCQB.

Bluestone is a reporting issuer in British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, New Brunswick, Newfoundland and Labrador, Nova Scotia and Prince Edward Island. Aura expects to apply to the applicable Canadian securities regulators to have Bluestone cease to be a reporting issuer following the completion of the Arrangement.

The Aura Shares are currently listed for trading on the TSX. It is anticipated that, after the completion of the Arrangement, Aura will continue to trade on the TSX.

The CVRs will not be listed on any stock exchange.

Aura is currently a reporting issuer in Alberta, British Columbia, Saskatchewan, Ontario, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia and Prince Edward Island. Aura will continue its reporting issuer status in each of such provinces in Canada upon completion of the Arrangement.


2024 Special Meeting of Securityholders

The issue of Aura Shares and CVRs pursuant to the Arrangement will constitute distributions of securities which are exempt from the prospectus requirements of Canadian Securities Laws and, subject to the satisfaction of certain conditions, will not be subject to resale restrictions. Recipients of Aura Shares and CVRs are urged to obtain legal advice to ensure that their resale of such securities complies with applicable Canadian Securities Laws.

United States Securities Law Matters

The following discussion is a general overview of certain requirements of U.S. federal and state securities laws applicable to Bluestone Shareholders and Bluestone Optionholders. All holders of such securities are urged to obtain legal advice to ensure that their resale of such securities complies with applicable U.S. Securities Laws.

The Aura Shares and CVRs to be issued pursuant to the Arrangement have not been and will not be registered under the U.S. Securities Act and will be issued in reliance on the exemption afforded by section 3(a)(10) of the U.S. Securities Act and applicable U.S. state securities laws in reliance upon similar exemptions under applicable U.S. state securities laws. Section 3(a)(10) of the U.S. Securities Act exempts from registration the offer and sale of a security which is issued in specified exchange transactions where, among other things, the fairness of the terms and conditions of such exchange are approved by a court or authorized governmental entity after a hearing on the fairness of such terms and conditions, at which all persons to whom it is proposed to issue securities in such exchange have the right to appear, by a court or governmental authority expressly authorized by law to grant such approval and to hold such a hearing. Accordingly, the Final Order, if granted by the Court, constitutes a basis for the exemption from the registration requirements of the U.S. Securities Act with respect to the Aura Shares and CVRs issued in connection with the Arrangement.

The Aura Shares and CVRs to be issued under the Arrangement will not be subject to resale restrictions under the U.S. Securities Act, except that the U.S. Securities Act imposes restrictions on the resale of Aura Shares and CVRs received pursuant to the Arrangement by persons who are at the time of a resale, or who were within 90 days prior to the completion of the Arrangement, or upon the completion of the Arrangement became, "affiliates" (as defined in Rule 144(a)(1) under the U.S. Securities Act) of Aura. As defined in Rule 144(a)(1) under the U.S. Securities Act, an "affiliate" of an issuer is a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, the issuer. Persons who are officers, directors or 10% or greater shareholders of an issuer are generally considered to be its "affiliates".

Bluestone Shareholders who are affiliates (or, if applicable, former affiliates) of Aura may not be able to resell the Aura Shares or CVRs that they receive pursuant to the Arrangement in the absence of registration under the U.S. Securities Act or reliance upon an exemption therefrom.

Subject to limitations for those that are affiliates other than solely by virtue of being directors or officers, such affiliates (and former affiliates) may immediately resell such Aura Shares and CVRs outside the United States, including through sales on the TSX in the case of Aura Shares, without registration under the U.S. Securities Act pursuant to and in accordance with Rule 904 of Regulation S under the U.S. Securities Act.

Any holder of Aura Shares or CVRs who is an affiliate (or, if applicable, former affiliate) of Aura at the time of a proposed resale is urged to consult with its own legal advisor to ensure that any proposed resale of Aura Shares or CVRs issued to them pursuant to the Arrangement complies with applicable U.S. Securities Act requirements.

(G) after the Aura Response Period, the Board (A) has determined in good faith, after consultation with its outside legal counsel and financial advisors, that such Acquisition Proposal continues to constitute a Superior Proposal (if applicable, compared to the terms of the Arrangement as proposed to be amended by Aura) and (B) has determined in good faith, after consultation with its outside legal counsel, that the failure by the Board to make a Bluestone Change in Recommendation and/or to cause Bluestone to terminate the Arrangement Agreement to enter into Bluestone Proposed Agreement, as applicable, would be inconsistent with its fiduciary duties; and

(H) in the case the Board is exercising its rights with respect to terminating the Arrangement Agreement to concurrently enter into a Bluestone Proposed Agreement, prior to or concurrently with terminating the Arrangement Agreement, Bluestone enters into such Bluestone Proposed Agreement and concurrently pays to Aura the amounts required to be paid pursuant to the Arrangement Agreement.

(iv) Each successive amendment or modification to any Acquisition Proposal or Bluestone Proposed Agreement that results in an increase in, or modification of, the consideration (or value of such consideration) to be received by Bluestone Shareholders or other material terms or conditions thereof shall constitute a new Acquisition Proposal for the purposes of the Arrangement Agreement, and Aura shall be afforded a new five Business Day Aura Response Period from the date on which Aura has received the notice and all documentation required in relation thereto with respect to the new Superior Proposal from Bluestone.

(v) The Board shall promptly reaffirm Bluestone Board Recommendation by press release after the Board determines that any Acquisition Proposal that is publicly announced is not a Superior Proposal or the Board determines that a proposed amendment to the terms of the Arrangement Agreement as would result in an Acquisition Proposal that has been previously announced no longer being a Superior Proposal, and the Arrangement Agreement has been so amended. Bluestone shall provide Aura and its outside legal counsel with a reasonable opportunity to review the form and content of any such press release and shall make all reasonable amendments to such press release as requested by Aura and its counsel.

(vi) In circumstances where Bluestone provides Aura with notice of a Superior Proposal and all documentation required in relation thereto on a date that is less than seven Business Days prior to the scheduled date of Bluestone Meeting, Bluestone may either proceed with or postpone Bluestone Meeting to a date that is not more than 10 Business Days after the scheduled date of such Bluestone Meeting, and shall postpone Bluestone Meeting to a date that is not more than 10 Business Days after the scheduled date of such Bluestone Meeting if so directed by Aura.

(vii) Nothing contained in the Arrangement Agreement shall prohibit the Board (acting in good faith and upon advice of its outside legal and financial advisors) from making any disclosure to Bluestone Shareholders as required by applicable Laws, including complying with section 2.17 of Multilateral Instrument 62-104 - Takeover Bids and Issuer Bids and similar provisions under Securities Laws relating to the provision of a directors' circular in respect of an Acquisition Proposal; provided, however, that neither Bluestone nor the Board shall be permitted to recommend that the Bluestone Shareholders tender any securities in connection with any take-over bid that is an Acquisition Proposal or effect a Bluestone Change in Recommendation with respect thereto, except as permitted by the non-solicitation and exclusivity provisions in the Arrangement Agreement.


2024 Special Meeting of Securityholders

Termination of Arrangement Agreement

The Arrangement Agreement may be terminated at any time prior to the Effective Time by the mutual written agreement of the Parties. The Arrangement Agreement may also be terminate prior to the Effective Time by either Bluestone or Aura if: (a) the Effective Time has not occurred on or before the Outside Date, provided that the Arrangement Agreement may not be terminated in such instance by a Party whose failure to fulfill its covenants or agreements or whose breach of any of its representations and warranties under the Arrangement Agreement has been the cause of or resulted in the failure of the Effective Time to occur by such Outside Date; (b) if the consummation of the Arrangement is made illegal or otherwise prohibited by a final and non-appealable law or order, provided that the Party seeking to terminate the Arrangement Agreement has complied in all material respects with its covenants under the Arrangement Agreement to appeal or overturn such law or order; or (c) if the Required Securityholder Approval has not been obtained in accordance with the Interim Order, provided that the Arrangement Agreement may not be terminated in such instance by a Party if the failure to obtain the Required Securityholder Approval has been caused by, or is a result of, a breach by such Party of any of its representations or warranties or the failure of such Party to perform any of its covenants or agreements under the Arrangement Agreement.

Company Termination Rights

Bluestone can terminate the Arrangement Agreement if (i) prior to obtaining the Required Securityholder Approval, the Board authorizes Bluestone to enter into a binding written agreement relating to a Superior Proposal and Bluestone pays to Aura the Termination Fee; (ii) any of the conditions precedent set forth under "The Arrangement - Conditions to Closing - Mutual Conditions" and "The Arrangement - Conditions to Closing - Company Conditions" is not satisfied, and such condition is incapable of being satisfied by the Outside Date; (iii) a breach of any representation or warranty or failure to perform any covenant or agreement on the part of Aura set forth in the Arrangement Agreement shall have occurred that would cause the conditions set forth in "The Arrangement - Conditions to Closing - Mutual Conditions" and "The Arrangement - Conditions to Closing - Company Conditions" not to be satisfied, and such conditions are incapable of being satisfied by the Outside Date; provided that Bluestone is not then in breach of the Arrangement Agreement so as to cause any of the conditions set forth in "The Arrangement - Conditions to Closing - Mutual Conditions" or "The Arrangement - Conditions to Closing - Purchaser Conditions" not to be satisfied; or (iv) there has occurred an Aura Material Adverse Effect.

Purchaser Termination Rights

Aura may terminate the Arrangement Agreement if (i) prior to the Effective Time, there is a Bluestone Change in Recommendation; (ii) Bluestone has not satisfied "The Arrangement - Conditions to Closing - Mutual Conditions" or "The Arrangement - Conditions to Closing - Purchaser Conditions" and such condition is incapable of being satisfied by the Outside Date; (iii) a breach of any representation or warranty or failure to perform any covenant or agreement on the part of Bluestone set forth in the Arrangement Agreement shall have occurred that would cause the conditions set forth in "The Arrangement - Conditions to Closing - Mutual Conditions" or "The Arrangement - Conditions to Closing - Purchaser Conditions" not to be satisfied, and such conditions are incapable of being satisfied by the Outside Date; provided that Aura is not then in breach of the Arrangement Agreement so as to cause any of the conditions set forth in "The Arrangement - Conditions to Closing - Mutual Conditions" or "The Arrangement - Conditions to Closing - Company Conditions" not to be satisfied; (iv) Bluestone willfully or materially breaches any of the non-solicitation and exclusivity provisions in the Arrangement Agreement; and (v) there has occurred a Bluestone Material Adverse Effect.

Termination Payment

The Arrangement Agreement contains a Termination Fee equal to US$2,000,000 payable by Bluestone to Aura in certain circumstances in connection with the termination of the Arrangement Agreement. The Termination Fee is payable if (i) Aura terminates the Arrangement Agreement due to a Bluestone Change in Recommendation or a wilful or material breach of the Company's exclusivity and non-solicitation obligations contained in the Arrangement Agreement; (ii) Bluestone terminates the Arrangement Agreement due to a Superior Proposal; (iii) (A) the Arrangement Agreement is terminated by any Party due to the Effective Time having not occurred before the Outside Date or the Required Securityholder Approval having not been obtained or (B) by Aura due to a negligent, wilful or fraudulent breach by Bluestone of its representations, warranties or covenants in the Arrangement Agreement, but only if, prior to the termination of the Arrangement Agreement, an Acquisition Proposal, or the intention to make an Acquisition Proposal, with respect to Bluestone shall have been made or publicly announced by any person (other than Aura or any of its affiliates) and has not expired or been withdrawn prior to the Meeting; and: (X) within 12 months following the date of such termination Bluestone enters into a definitive agreement in respect of that Acquisition Proposal and such Acquisition Proposal is later consummated (whether or not within such 12-month period); or (Y) within 12 months following the date of such termination that Acquisition Proposal is consummated, except that a reference to "20%" therein shall be deemed to be a reference to "50%". Any Termination Fee is intended to be proceeds to Aura for the disposition of its contractual right to acquire Bluestone Securities under the Arrangement Agreement.


2024 Special Meeting of Securityholders

Amendments

The Arrangement Agreement and the Plan of Arrangement may, at any time and from time to time before or after the holding of the Meeting, but not later than the Effective Time, be amended by mutual written agreement of the Parties, and any such amendment may, subject to the Interim Order, the Final Order and applicable law, without limitation (i) change the time for performance of any of the obligations or acts of the Parties; (ii) waive any inaccuracies or modify any representation or warranty contained in the Arrangement Agreement or in any document delivered pursuant thereto; (iii) make any administrative amendments required to be made in connection with assignment by Aura in accordance with the Arrangement Agreement; (iv) waive compliance with or modify any of the covenants contained in the Arrangement Agreement; (v) waive or modify performance of any of the obligations of the Parties; and/or (vi) waive compliance with or modify any mutual conditions precedent contained in the Arrangement Agreement.

Expenses

Except as otherwise provided in the Arrangement Agreement, all fees, costs and expenses incurred in connection with the Arrangement Agreement and the Arrangement shall be paid by the Party incurring such fees, costs or expenses.

THE RIGHTS INDENTURE

The following is a summary of the principal terms of the Rights Indenture, the form of which is attached as Appendix J to this Circular, and does not purport to be complete and is qualified in its entirety by reference to the Rights Indenture. Capitalized term used but not otherwise defined herein have the meanings set out in the Rights Indenture.

CVRs

Pursuant to the Arrangement, each Bluestone Shareholder (other than a Dissenting Shareholder) will receive from Aura on the Effective Date, in exchange for each Bluestone Share held or to be issued at the Effective Time, as applicable, one CVR entitling such holders to receive, without any further consideration and without further action on the part of the holder thereof, up to $0.2120 in cash provided that the CVR Payment Conditions are satisfied prior to the CVR Termination Date. The terms and conditions governing the CVRs are set out in the Rights Indenture attached as Appendix J to this Circular.

All CVRs will rank pari passu. CVRs do not represent any equity or ownership interest in Aura or any of its affiliates, or in any of their assets, including but not limited to any interest in the Cerro Blanco Project or any assets or mineral relating to the Cerro Blanco Project. Nothing in the Rights Indenture or in the holding of a CVR itself (whether evidenced by a Rights Certificate or otherwise) will confer upon a holder of a CVR any voting, dividend or other rights in respect of Aura and interest will not accrue for the benefit of the holder of a CVR on any amounts payable in respect of the CVRs.

The CVRs will be freely trading securities in Canada and freely transferable securities in the United States (other than by "affiliates" of Aura, as such term is defined in Rule 144). The CVRs will not be listed on any stock exchange.


2024 Special Meeting of Securityholders

Upon the earlier of the completion of the CVR Payment Amount in full for each CVR held or at the CVR Termination Date, (i) the CVRs will terminate and be null, void and of no effect; and (ii) all the Rights Certificates shall be cancelled.

CVR Payment Condition and Procedures

CVR Payment Condition

Payment under the CVRs is conditional upon the CVR Payment Conditions being satisfied prior to the CVR Termination Date. Under the Rights Indenture, the CVR Payment Amount payable until the CVR Termination Date pursuant to the following schedule: (A) upon satisfaction of the First Payment Condition, 33.33% of the CVR Payment Amount, being $0.0707; (B) upon satisfaction of the Second Payment Condition, 33.33% of the CVR Payment Amount, being $0.0707; and (C) upon satisfaction of the Third Payment Condition, the balance of the CVR Payment Amount, being $0.0706.

CVR Payment Condition Satisfied

If a CVR Payment Condition is met prior to the CVR Termination Date: (a) Aura will, as soon as practicable, deliver to the Trustees a notice in writing (the "Achievement Certificate") signed on behalf of Aura by one or more officers (without personal liability) certifying that such CVR Payment Condition has been satisfied. The Canadian Trustee will promptly deliver a copy of such Achievement Certificate to the CVR Holders; (b) each CVR Holder shall receive, at no additional cost or expense, the portion of the CVR Payment Amount as set out in the Rights Indenture for each CVR held on the applicable CVR Payment Date.

After each CVR Payment Date, all CVRs shall be deemed after such CVR Payment Date to represent only the right to receive the remaining CVR Payment Amount to which the holder thereof is entitled in lieu of such CVRs.

CVR Payment Conditions Not Satisfied

If any CVR Payment Condition is not met prior to the CVR Termination Date, Aura will, as soon as practicable, deliver to the Trustees a notice in writing (the "Non-Achievement Certificate") signed on behalf of Aura by one or more officers (without personal liability) certifying that such CVR Payment Condition has not been satisfied by the CVR Termination Date and that Aura has complied in all material respects with its obligations under the Rights Indenture. The Canadian Trustee will promptly deliver a copy of such Non-Achievement Certificate to the CVR Holders.

Fractional Aura Shares

To the extent that the holder of one or more CVRs would otherwise have been entitled to receive on the conversion of the CVRs a fraction of a cent, the consideration payable shall be rounded up to the nearest whole cent.

Covenants of Aura

Aura will make certain covenants pursuant to the Rights Indenture, including that, from the Effective Date until the earlier of the full CVR Payment Date and the CVR Termination Date, Aura will, among other things:

(a) use its commercially reasonable efforts to continue the exploration and advancement towards development of the Cerro Blanco Project;

(b) not, directly or indirectly, complete or take any action or enter into any agreement, arrangement or understanding, whether by a sale of assets or by merger, reorganization, joint venture, lease, license, trust or any other transaction or arrangement, for the sale, transfer, assignment, disposition, relinquishment or surrender of its rights, title or interest in or to the Cerro Blanco Project or in or to any material assets comprising the Cerro Blanco Project to any person (a "Cerro Blanco Project Transfer") unless: (i) Aura satisfies the full CVR Payment Amount on or prior to the effective date of the Cerro Blanco Transfer; (ii) (A) the transfer is approved by Extraordinary Resolution of the holders of CVRs, and (B) the agreement for such Cerro Blanco Transfer required the applicable transferee to comply with the Rights Indenture to the same extent as Aura and releases Aura from all obligations and liabilities under the Rights Indenture; (iii) Aura (or its corporate successor) first agrees in writing to remain subject to the obligations under the Rights Indenture, including to make payments if and when such a payment is due in accordance with the terms of the Rights Indenture; and (iv) the agreement for such Cerro Blanco Project Transfer requires the applicable transferee to comply with the Rights Indenture to the same extent as Aura and such transferee has first agreed in writing to that effect;


2024 Special Meeting of Securityholders

(c) use commercially reasonable efforts to keep or cause to be kept proper books of account for its operations at the Cerro Blanco Project and enter into those books all dealings and transactions in relation to the Cerro Blanco Project; and

(d) prepare and deliver certain reports to the Trustees and CVR Holders as required under the TIA and applicable Laws.

Restrictions on Purchases by Aura and Affiliates

Aura and its affiliates are not prohibited from acquiring CVRs, whether in open market transactions, private transactions or otherwise, provided such acquisitions comply with Canadian and U.S. securities laws or other applicable securities laws. Rights Certificates representing the CVRs purchased by Aura pursuant to the Rights Indenture shall be immediately surrendered to the Trustees for cancellation and shall not be reissued. Aura shall not be entitled to vote on any matter to be voted upon and shall not be entitled to dispute any matter in the Rights Indenture.

Dispute Mechanics

If CVR Holders of at least 25% of the outstanding CVRs (the "Required Holders") at any time but no later than 60 calendar days after the CVR Termination Date (the "Dispute Period") wish to dispute satisfaction or non-satisfaction of the CVR Payment Condition, the Required Holders may provide Aura and the Canadian Trustees with written notice (the "Dispute Notice") of such dispute in reasonable detail.

If the Required Holders do not deliver such a Dispute Notice on or prior to the expiry of the Dispute Period, the Required Holders will be deemed to have accepted that the CVR Payment Condition has not been met, and Aura and its affiliates will have no further obligation with respect to the CVRs or the CVR Payment Amount.

If the Required Holders deliver a Dispute Notice during the Dispute Period, and it is finally determined in accordance with the Rights Indenture that the CVR Payment Condition has been met, the CVR Payment Amount will be paid on a date established by Aura that is as soon as possible after such determination.

Aura shall work in good faith together with Required Holders who have provided a Dispute Notice to resolve the dispute set out in the Rights Indenture on a mutually satisfactory basis for not less than 30 days, following which the dispute may be referred to arbitration pursuant to Rights Indenture.

Events of Default

The occurrence of any of the following events prior to the earlier of the full CVR Payment Date and the CVR Termination Date, will constitute an event of default (each, an "Event of Default") under the Rights Indenture:

(a) Aura fails to observe or perform in any material respect any covenant, condition or agreement contained in the Rights Indenture or in respect of the CVRs and such failure shall continue unremedied for a period of 120 days after written notice has been given to Aura by the Trustees or to Aura and the Trustees by any Required Holders specifying such failure and requiring it to be remedied;


2024 Special Meeting of Securityholders

(b) a court having competent jurisdiction over Aura entering a decree or order (i) for relief in respect of Aura following the filing of any petition, application or other proceeding against or in respect of Aura by or on behalf of a person (other than Aura) under any applicable bankruptcy, insolvency or other similar law now or thereafter in effect, or (ii) appointing a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of Aura or for any substantial part of its property or ordering the winding up or liquidation of its affairs, and in case of (i) or (ii), such decree or order remaining unstayed and in effect for a period of 30 consecutive days; or

(c) Aura voluntarily (i) commencing or filing any petition, application or other proceeding under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, (ii) consenting to the entry of an order for relief under any proceeding initiated against or in respect of Aura by or on behalf of a person (other than Aura) under any such law, (iii) consenting to the appointment of or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator (or similar official) of Aura or for any substantial part of its property, or (iv) making any general assignment for the benefit of its creditors.

If an Event of Default described in item (a) above occurs and is continuing, then either the Canadian Trustee by notice to Aura or the Canadian Trustee upon the written request of Required Holders with notice to Aura and to the Trustees, will bring the matter to binding arbitration in order to protect the rights of the CVR Holders, including to obtain payment for any amounts then due and payable. If an Event of Default described in items (b) or (c) above occurs, then the CVRs in aggregate will thereafter automatically be converted into and represent an unsecured claim for the outstanding balance of the CVR Payment Amount plus any additional amount determined to be due and payable to CVR Holders by Aura pursuant to any arbitration under the Rights Indenture, regardless of the satisfaction of the CVR Payment Conditions (for greater certainty, such unsecured claim shall rank pari passu with other unsecured claims of Aura).

RISK FACTORS

In evaluating the Arrangement, Bluestone Securityholders should carefully consider the following risk factors relating to the Arrangement. The following risk factors are not a definitive list of all risk factors associated with the Arrangement. Additional risks and uncertainties, including those currently unknown or considered immaterial by Bluestone, may also adversely affect the trading price of the Bluestone Shares, the Aura Shares and/or the businesses of Bluestone and Aura following the Arrangement. In addition to the risk factors relating to the Arrangement set out below, Bluestone Securityholders should also carefully consider the risk factors associated with the businesses of Bluestone and Aura under the headings "Information Concerning Aura Following the Arrangement" and "Information Concerning Aura" in this Circular and in the documents incorporated by reference herein. If any of the risk factors materialize, the expectations, and the predictions based on them, may need to be re-evaluated.

Risks Related to the Arrangement

The completion of the Arrangement is subject to conditions precedent

The completion of the Arrangement is subject to a number of conditions precedent, some of which are outside of Bluestone or Aura's control, including receipt of the Final Order, receipt of the Required Securityholder Approval, receipt of TSXV and TSX approvals, and receipt of the Key Consents and Approvals.

In addition, the completion of the Arrangement is conditional on, among other things, no Bluestone Material Adverse Effect or Aura Material Adverse Effect having occurred, or having been disclosed to the public (if previous undisclosed to public) in respect of the other Party.


2024 Special Meeting of Securityholders

There can be no certainty, nor can Bluestone or Aura provide any assurance, that all conditions precedent to the Arrangement will be satisfied or waived, or if satisfied or waived, when they will be satisfied or waived and, accordingly, the Arrangement may not be completed. If the Arrangement is not completed, the market price of Bluestone Shares and/or Aura Shares may be adversely affected.

The Key Consents and Approvals may not be obtained or, if obtained, may not be obtained on a favourable basis or in a timely manner

To complete the Arrangement, each of Bluestone and Aura must make certain filings with and obtain certain consents and approvals from governmental and regulatory authorities. The Key Consents and Approvals have not been obtained yet. The regulatory approval processes may take a lengthy period of time to complete, which could delay completion of the Arrangement. If obtained, the Key Consents and Approvals may be conditioned, with the conditions imposed by the applicable Governmental Entity not being acceptable to either Bluestone or Aura, or, if acceptable, not being on terms that are favourable to the Combined Company. There can be no assurance as to the outcome of the regulatory approval processes, including the undertakings and conditions that may be required for approval or whether the Key Consent and Approvals will be obtained. If not obtained, or if obtained on terms that are not satisfactory to either Bluestone and Aura, the Arrangement may not be completed.

Bluestone Shareholders that elect the Share Consideration may be subject to pro-ration in accordance with the Arrangement

If the total elections for the Share Consideration exceed the Aggregate Share Consideration, it is likely that Bluestone Shareholders will not receive 100% of the Share Consideration that they have elected or are deemed to have elected to receive.

The number of Aura Shares to be received under an election to receive Aura Shares as Consideration is fixed and will likely vary from the market value of the Cash Consideration

Bluestone Shareholders will have the right to elect to receive, or may as a result of pro-ration or the deeming provisions under the Arrangement, receive a fixed number of Aura Shares, and one CVR in exchange for each Bluestone Share held, under the Arrangement rather than receiving Aura Shares with a fixed market value. Because the Aura Shares to be received in respect of each Bluestone Share under the Arrangement will not be adjusted to reflect changes in the market price of the Aura Shares, the market value of the Aura Shares received under the Arrangement will likely vary from the value of the Cash Consideration that may be received under the Arrangement.

The market price of the Bluestone Shares and Aura Shares may be materially adversely affected in certain circumstances

If, for any reason, the Arrangement is not completed or its completion is materially delayed and/or the Arrangement Agreement is terminated, the market price of Bluestone Shares may be materially adversely affected and decline to the extent that the current market price of the Bluestone Shares reflects a market assumption that the Arrangement will be completed. Depending on the reasons for terminating the Arrangement Agreement, Bluestone's business, financial condition or results of operations could also be subject to various material adverse consequences, including as a result of paying the Termination Fee, as applicable in connection to the Arrangement.

The Arrangement Agreement may be terminated in certain circumstances

Aura has the right, in certain circumstances, in addition to termination rights relating to the failure to satisfy the conditions of closing, to terminate the Arrangement. Accordingly, there can be no certainty, nor can Aura provide any assurance that the Arrangement will not be terminated by Aura prior to the completion of the Arrangement. In addition, if the Arrangement is not completed by the Outside Date, Aura may terminate the Arrangement Agreement. The Arrangement Agreement also includes termination amounts payable if the Arrangement Agreement is terminated in certain circumstances. Additionally, any termination will result in the failure to realize the expected benefits of the Arrangement in respect of the operations and business of Bluestone.


2024 Special Meeting of Securityholders

If the Arrangement Agreement is terminated, there is no assurance that the Board will be able to find a party willing to pay an equivalent or greater price than the Consideration to be paid pursuant to the terms of the Arrangement Agreement.

The completion of the Arrangement is uncertain and Bluestone will incur costs even if the Arrangement is not completed

As the Arrangement is dependent upon receipt, among other things, of the Key Consents and Approvals and satisfaction of certain other conditions, its completion is uncertain. If the Arrangement is not completed for any reason, there are risks that the announcement of the Arrangement and the dedication of Bluestone's resources to the completion thereof could have a negative impact on Bluestone's relationships with its stakeholders and could have a material adverse effect on the current and future operations, financial condition and prospects of Bluestone.

In addition, certain costs related to the Arrangement, such as legal, accounting and certain financial advisor fees, must be paid by Bluestone and Aura even if the Arrangement is not completed. Bluestone and Aura are each liable for their own costs incurred in connection with the Arrangement. If the Arrangement is not completed, Bluestone may be required to pay Aura the Termination Fee. See "The Arrangement Agreement - Termination of Arrangement Agreement" in this Circular.

The Arrangement may divert the attention of Bluestone's Management

The Arrangement could cause the attention of the Bluestone's management to be diverted from the day-to-day operations of Bluestone. These disruptions could be exacerbated by a delay in the completion of the Arrangement and could have an adverse effect on the business, operating results or prospects of Bluestone.

The Termination Fee provided under the Arrangement Agreement may discourage other parties from attempting to acquire Bluestone

Under the Arrangement Agreement, Bluestone would be required to pay a Termination Fee of US$2,000,000 if the Arrangement Agreement is terminated in certain circumstances. This Termination Fee may discourage other parties from attempting to acquire Bluestone Shares or otherwise making an Acquisition Proposal to Bluestone, even if those parties would otherwise be willing to offer greater value to Bluestone Securityholders than that offered by Aura under the Arrangement.

Restrictions from pursuing business opportunities

Bluestone is also subject to customary non-solicitation provisions under the Arrangement Agreement, pursuant to which, Bluestone is restricted from soliciting, initiating or knowingly encouraging any Acquisition Proposal, among other things. The Arrangement Agreement also restricts Bluestone from taking specified actions until the Arrangement is completed without the consent of Aura. These restrictions may prevent Bluestone from pursuing attractive business opportunities that may arise prior to the completion of the Arrangement.

The Aura Shares issued in connection with the Arrangement may have a market value different than expected

Each Bluestone Shareholder will have the option to elect to receive the Share Consideration. Because the Share Consideration will not be adjusted to reflect any changes in the market value of Aura Shares, the market values of the Aura Shares and the Bluestone Shares at the Effective Time may vary significantly from the values at the date of this Circular. If the market price of Aura Shares declines, the value of the consideration received by Bluestone Shareholders electing or deemed to elect to receive Aura Shares for Bluestone Shares will decline as well. Variations may occur as a result of changes in, or market perceptions of changes in, the business, operations or prospects of Aura, market assessments of the likelihood that the Arrangement will be consummated, regulatory considerations, general market and economic conditions, changes in the prices of metals and other factors, including those factors over which neither Bluestone nor Aura has control.


2024 Special Meeting of Securityholders

Directors and officers of Bluestone have interests in the Arrangement that may be different from those of Bluestone Shareholders generally

In considering the recommendation of the Board with respect to the Arrangement, Bluestone Shareholders should be aware that certain members of Bluestone's senior management and the Board have certain interests in connection with the Arrangement that may present them with actual or potential conflicts of interest in connection with the Arrangement. See "The Arrangement - Interests of Certain Persons in the Arrangement" in this Circular.

The foregoing risks or other risks arising in connection with the failure of the Arrangement, including the diversion of management attention from conducting the business of Bluestone, may have a material adverse effect on Bluestone's business operations, financial condition, financial results and share price.

Aura and Bluestone may be the targets of legal claims, securities class action, derivative lawsuits and other claims

Aura and Bluestone may be the target of securities class action and derivative lawsuits which could result in substantial costs and may delay or prevent the Arrangement from being completed. Securities class action lawsuits and derivative lawsuits are often brought against companies that have entered into an agreement to acquire a public company or to be acquired. Third parties may also attempt to bring claims against Aura or Bluestone seeking to restrain the Arrangement or seeking monetary compensation or other redress. Even if the lawsuits are without merit, defending against these claims can result in substantial costs and divert management time and resources. Additionally, if a plaintiff is successful in obtaining an injunction prohibiting consummation of the Arrangement, then that injunction may delay or prevent the Arrangement from being completed.

Risks Related to the CVRs

CVR Holders may never receive the CVR Payment Amount

If the CVR Payment Conditions are not satisfied for any reason prior to the CVR Termination Date, the full CVR Payment Amount will not be paid out and Bluestone Shareholders will not realize the value of the Contingent Consideration.

CVR Payment Amounts rank at parity with other unsecured claims of Aura

Should certain Events of Default occur pursuant to the Rights Indenture, the CVRs will automatically be converted into and represent an unsecured claim for the outstanding balance of the CVR Payment Amount with such unsecured claim ranking pari passu with other unsecured claims of Aura. In the event of a shortfall of funds after paying secured creditors of Aura, CVR Holders will not receive the full CVR Payment Amount they may otherwise have been entitled to.

The CVRs will not be listed on any exchange

Although they will be transferable, the CVRs will not be listed on any securities exchange. Accordingly, a CVR Holder may not have an ability to realize the value of the full CVR Payment Amount in accordance with the terms of the Rights Indenture prior to the CVR Payment Date.

The treatment of CVRs for U.S. federal income tax purposes is unclear

There is no legal authority directly addressing the U.S. federal income tax treatment of CVRs received pursuant to the Arrangement. Accordingly, the amount, timing and character of any gain, income or loss with respect to the CVRs are uncertain. U.S. Holders should consult their own tax advisors concerning the recognition of income, gain or loss, if any, resulting from the receipt of a CVR or the receipt of any payment in respect of a CVR, and review the discussion under "Certain U.S. Federal Income Tax Consequences of the Arrangement".


2024 Special Meeting of Securityholders

Bluestone expects to be classified as a "passive foreign investment company" ("PFIC") under the Code, and Aura may be a PFIC, which would subject U.S. Holders to adverse U.S. federal income tax consequences. Certain tax elections to mitigate these tax consequences may not be available to U.S. Holders.

Generally, unfavorable U.S. federal income tax rules apply to U.S. Holders that own stock of a PFIC. A non-U.S. corporation will be considered a PFIC for any taxable year in which (i) 75% or more of its gross income is "passive income," or (ii) 50% or more of the average value of its assets is attributable to "passive assets" (generally, assets that generate passive income). Based on current business plans and financial expectations, Bluestone expects to be classified as a PFIC during its tax year which includes the Effective Date, and believes it has been a PFIC in prior tax years, while Aura does not expect to be classified as a PFIC for its tax year which includes the day after the Effective Date. No opinion of legal counsel or ruling from the IRS concerning Bluestone's or Aura's status as a PFIC has been obtained or is currently planned to be requested. The determination of PFIC status for any year is based on the types of income each of Bluestone and Aura earn and the types and value of their respective assets from time to time, all of which are subject to change, as well as, in part, the application of complex U.S. federal income tax rules, which are subject to change and differing interpretations.

If Bluestone or Aura were classified as a PFIC for any taxable year during which a U.S. Holder holds Bluestone Shares or Aura Shares, as applicable, such holder may be subject to increased tax liability (generally including an interest charge) upon the sale or other disposition of such shares or upon the receipt of certain actual and deemed distributions treated as "excess distributions." In addition, certain elections that generally mitigate these adverse tax results may be unavailable for U.S. Holders. See "Certain U.S. Federal Income Tax Consequences of the Arrangement-U.S. Federal Income Tax Consequences of the Exchange of Bluestone Shares for CVRs and Aura Shares and/or Cash Consideration Pursuant to the Arrangement-Tax Consequences of the Arrangement if Bluestone Is Classified as a PFIC" and "Certain U.S. Federal Income Tax Consequences of the Arrangement-U.S. Federal Income Tax Consequences of the Ownership and Disposition of Aura Shares-Passive Foreign Investment Company Rules Relating to the Ownership of Aura Shares" for additional discussion.

2024 Special Meeting of Securityholders

INFORMATION CONCERNING AURA FOLLOWING THE ARRANGEMENT

On completion of the Arrangement, Aura will continue to be a corporation incorporated under the laws of the British Virgin Islands. On the Effective Date, Aura will own all of the Bluestone Shares and Bluestone will be a wholly owned subsidiary of Aura.

For further information regarding the Combined Company after the completion of the Arrangement please see Appendix G - Information Concerning Aura Following the Arrangement.

CERTAIN CANADIAN FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary as of the date hereof of the principal Canadian federal income tax considerations under the Tax Act of the Arrangement generally applicable to a Bluestone Shareholder who, for purposes of the Tax Act and at all relevant times (i) holds Bluestone Shares and will hold Aura Shares, if applicable, and CVRs acquired pursuant to the Arrangement as capital property, and (ii) deals at arm's length with, and is not affiliated with, Bluestone or Aura (a "Holder"). Bluestone Shares, Aura Shares and CVRs generally will be considered capital property to a Holder for purposes of the Tax Act unless the Holder holds such securities in the course of carrying on a business of buying and selling securities or the Holder has acquired or holds such securities in a transaction or transactions considered to be an adventure or concern in the nature of trade.

This summary is based on: (i) the current provisions of the Tax Act in force as of the date of this Circular, (ii) counsel's understanding of the administrative policies and assessing practices of the CRA that are publicly available and published in writing prior to the date of this Circular, (iii) all specific proposals to amend the Tax Act that have been publicly and officially announced by or on behalf of the Minister of Finance (Canada) prior to the date of this Circular (the "Proposed Amendments"), and (iv) the facts set out in this Circular. This summary assumes that the Proposed Amendments will be enacted in the form proposed, although no assurance can be given that the Proposed Amendments will be enacted in the form proposed, or at all. This summary does not otherwise take into account or anticipate any other changes in law, whether by judicial, governmental or legislative decision or action or changes in the administrative policies or assessing practices of the CRA, nor does it take into account other federal or any provincial, territorial or foreign income tax legislation or considerations, which may differ materially from the Canadian federal income tax considerations discussed below.

This summary is not applicable to a Holder (i) that is a "financial institution" for the purposes of the mark-to-market rules in the Tax Act, (ii) that is a "specified financial institution" (as defined in the Tax Act), (iii) an interest in which is, or whose Bluestone Shares, Aura Shares or CVRs are (or would be), a "tax shelter investment" (as defined in the Tax Act), (iv) who has made an election pursuant to the functional currency reporting election rules in the Tax Act, (v) that is a "foreign affiliate" (as defined in the Tax Act) of a taxpayer resident in Canada, (vi) that has entered into a "synthetic disposition agreement" or a "derivative forward agreement" (as those terms are defined in the Tax Act) with respect to the Bluestone Shares, Aura Shares or CVRs, (vii) that will receive dividends on Aura Shares under or as part of a "dividend rental arrangement" (as defined in the Tax Act), (viii) that is exempt from tax under the Tax Act, or (ix) that is otherwise of special status or in special circumstances. This summary is not applicable to persons holding Bluestone Options. All such Holders should consult their own tax advisors with respect to the consequences of the Arrangement.

Additional considerations, not discussed in this summary, may be applicable to a Holder that is a corporation resident in Canada, and is, or becomes, or does not deal at arm's length for purposes of the Tax Act with a corporation resident in Canada that is or becomes, as part of a transaction or event or series of transactions or events that includes the acquisition of the Aura Shares (if applicable), controlled by a non-resident person, or group of non-resident persons not dealing with each other at arm's length, for purposes of the "foreign affiliate dumping" rules in section 212.3 of the Tax Act. Any such Holder should consult its own tax advisor with respect to the consequences of acquiring Aura Shares (if applicable).

THIS SUMMARY IS NOT EXHAUSTIVE OF ALL POSSIBLE CANADIAN FEDERAL INCOME TAX CONSIDERATIONS APPLICABLE TO THE ARRANGEMENT. THIS SUMMARY IS OF A GENERAL NATURE ONLY AND IS NOT AND SHOULD NOT BE CONSTRUED AS LEGAL OR TAX ADVICE TO ANY PARTICULAR PERSON (INCLUDING A HOLDER AS DEFINED ABOVE) AND NO REPRESENTATIONS CONCERNING THE TAX CONSEQUENCES TO ANY PARTICULAR HOLDER ARE MADE. THE TAX CONSEQUENCES OF THE ARRANGEMENT WILL VARY ACCORDING TO THE HOLDER'S PARTICULAR CIRCUMSTANCES. HOLDERS SHOULD CONSULT THEIR OWN INCOME TAX ADVISORS WITH RESPECT TO THE TAX CONSEQUENCES OF THE ARRANGEMENT APPLICABLE TO THEM BASED ON THEIR OWN PARTICULAR CIRCUMSTANCES, INCLUDING THE APPLICATION AND EFFECT OF THE INCOME AND OTHER TAX LAWS OF ANY COUNTRY, PROVINCE OR OTHER JURISDICTION THAT MAY BE APPLICABLE TO THE HOLDER. THIS SUMMARY DOES NOT ADDRESS ANY TAX CONSIDERATIONS APPLICABLE TO PERSONS OTHER THAN HOLDERS AND SUCH PERSONS SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE CONSEQUENCES OF THE ARRANGEMENT UNDER THE TAX ACT AND ANY JURISDICTION IN WHICH THEY MAY BE SUBJECT TO TAX.


2024 Special Meeting of Securityholders

Generally, for purposes of the Tax Act, all amounts relating to the acquisition, holding or disposition of Bluestone Shares, Aura Shares, or CVRs (including dividends, adjusted cost base and proceeds of disposition, as applicable) must be expressed in Canadian dollars based on the exchange rates as determined in accordance with the Tax Act.

This summary is based upon the understanding of counsel that a CVR evidences a contractual right to acquire cash on the satisfaction of certain conditions. No advance tax ruling in respect of the Arrangement has been sought from the CRA and counsel is not aware of any relevant judicial authority relating to this characterization for tax purposes.

Holders Resident in Canada

The following portion of this summary is generally applicable to a Holder who, at all relevant times, is a resident of Canada or who is deemed to be a resident of Canada for purposes of the Tax Act (a "Resident Holder"). Certain Resident Holders who might not otherwise be considered to own Bluestone Shares as capital property may be entitled to have them and all other "Canadian securities", as defined in the Tax Act, treated as capital property by making the irrevocable election permitted by subsection 39(4) of the Tax Act. This election does not apply to CVRs or Aura Shares. Resident Holders contemplating making a subsection 39(4) election should consult their own tax advisors for advice as to whether the election is available or advisable in their particular circumstances.

Disposition or Exchange of Bluestone Shares

A Resident Holder who exchanges Bluestone Shares pursuant to the Arrangement will be considered to have disposed of the Bluestone Shares for proceeds of disposition equal to the total amount of the: (i) cash received (if any), (ii) the aggregate fair market value of Aura Shares received (if any) at the time of the Arrangement, and (iii) subject to the discussion below under "Holders Resident in Canada - Receipt, Holding and Disposition of CVRs", the aggregate fair market value of the CVRs received at the time of the Arrangement. As a result, the Resident Holder will generally realize a capital gain (or capital loss) to the extent that such proceeds of disposition, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base of the Bluestone Shares immediately before the exchange. See "Holders Resident in Canada - Capital Gains and Capital Losses" below for a general discussion of the treatment of capital gains and capital losses under the Tax Act.

The cost to the Resident Holder of any Aura Shares acquired on such exchange will be equal to the fair market value of the Aura Shares at the time of the exchange. The Resident Holder's adjusted cost base of the Aura Shares so acquired will be determined by averaging such cost with the adjusted cost base to the Resident Holder of all Aura Shares owned by the Resident Holder as capital property immediately prior to such exchange.

Receipt, Holding and Disposition of CVRs

The cost to a Resident Holder of a CVR received pursuant to the Arrangement will be equal to the fair market value of the CVR received at the time of the Arrangement.


2024 Special Meeting of Securityholders

Resident Holder who disposes of a CVR, including pursuant to the termination of the CVR when all of the payment obligations under the CVR have been satisfied, should realize a capital gain (or capital loss) to the extent that the proceeds of disposition received by such Holder, which should include, although not free from doubt, the payments received pursuant to the CVRs, if any, exceed (or are less than) the aggregate of the Holder's adjusted cost base in its CVR immediately before the disposition and any reasonable costs of disposition. Where no payment on the CVR is to be made or in the event of the termination of a CVR where it is cancelled pursuant to the Rights Indenture, a Resident Holder should be considered to have disposed of its CVR for no proceeds and will realize a capital loss equal to the adjusted cost base of such CVR. See "Holders Resident in Canada - Capital Gains and Capital Losses" below for a general discussion of the treatment of capital gains and capital losses under the Tax Act.

The Canadian federal income tax consequences to a Resident Holder of the receipt, holding and disposition of a CVR, including the tax consequences of the receipt of payment pursuant to the CVR, are not entirely free from doubt. Resident Holders should consult their own tax advisors to determine the tax consequences and corresponding reporting in relation to the receipt, holding and disposition of a CVR and, in particular, whether the receipt of the CVRs and payments received under the CVRs should be reported in an alternative manner to that described above.

Dividends on Aura Shares

A Resident Holder will be required to include in computing such Resident Holder's income for a taxation year the amount of any dividends including amounts deducted for foreign withholding tax, if any, received on the Aura Shares. Dividends received on Aura Shares by a Resident Holder who is an individual (including certain trusts) will not be subject to the gross-up and dividend tax credit rules in the Tax Act normally applicable to taxable dividends received from taxable Canadian corporations. A Resident Holder that is a corporation will be required to include dividends received on Aura Shares in computing its income and will not be entitled to deduct the amount of such dividends in computing its taxable income.

To the extent that foreign withholding tax is payable by a Resident Holder in respect of any dividends received on Aura Shares, the Resident Holder may be eligible for a foreign tax credit or deduction to the extent and under the circumstances described in the Tax Act. Resident Holders should consult their own tax advisors regarding the availability of a foreign tax credit or deduction in their particular circumstances.

Dispositions of Aura Shares

A Resident Holder who disposes or is deemed to dispose of an Aura Share (including on a purchase of Aura Shares for cancellation by Aura) generally will realize a capital gain (or capital loss) equal to the amount, if any, by which the proceeds of disposition therefor exceed (or are exceeded by) the adjusted cost base to the Resident Holder of the Aura Share immediately before the disposition or deemed disposition and any reasonable expenses incurred for the purpose of making the disposition. See "Holders Resident in Canada - Capital Gains and Capital Losses" below for a general description of the treatment of capital gains and capital losses under the Tax Act.

Capital Gains and Capital Losses

Subject to the Capital Gains Proposals (defined below), a Resident Holder will generally be required to include in computing its income for a taxation year one-half of the amount of any capital gain (a "taxable capital gain") realized by it in that year. Such a Resident Holder will be required to deduct one-half of the amount of any capital loss (an "allowable capital loss") realized by it in a taxation year from taxable capital gains realized by the Resident Holder in that year. Allowable capital losses in excess of taxable capital gains realized in a taxation year may be carried back to any of the three preceding taxation years or carried forward to any subsequent taxation year and deducted against net taxable capital gains realized in such years, subject to and in accordance with the detailed rules contained in the Tax Act.

Proposed Amendments related to the capital gains inclusion rate (the "Capital Gains Proposals") would increase a Resident Holder's capital gains inclusion rate for a taxation year ending after June 24, 2024 from one-half to two-thirds, subject to transitional rules applicable for a Resident Holder's taxation year beginning on or before June 24, 2024 and ending on or after June 25, 2024 that would reduce the capital gains inclusion rate for that taxation year to be, in effect, one-half for net capital gains realized before June 25, 2024. The Capital Gains Proposals also include provisions that would, generally, offset the increase in the capital gains inclusion rate for up to $250,000 of net capital gains realized (or deemed to be realized) by a Resident Holder that is an individual (including certain trusts) in the year that are not offset by net capital losses carried back or forward from another taxation year. The Capital Gains Proposals also provide that capital losses realized prior to June 25, 2025, which are deductible against capital gain included in income for taxation years ending on or after June 25, 2024 will offset an equivalent capital gain regardless of the inclusion rate which applied at the time such capital losses were realized.


2024 Special Meeting of Securityholders

The foregoing summary only generally describes the considerations applicable under the Capital Gains Proposals and is not an exhaustive summary of the considerations that could arise in respect of the Capital Gains Proposals. The Capital Gains Proposals are complex and their application to a particular Resident Holder will depend on the Resident Holder's particular circumstances. Resident Holders should consult their own tax advisors with respect to the Capital Gains Proposals.

Dissenting Resident Holders

A Resident Holder who, as a result of the exercise of Dissent Rights, is entitled to be paid the fair value of its Bluestone Shares by Bluestone will be deemed to have received a dividend equal to the amount, if any, by which the payment received for such Bluestone Shares (less the amount in respect of interest, if any, awarded by a court) exceeds the paid-up capital of such Bluestone Shares (as determined under the Tax Act). Dissenting Resident Holders should consult their own tax advisors with respect to the tax consequences of such deemed dividend.

A dissenting Resident Holder will also be considered to have disposed of such Resident Holder's Bluestone Shares for proceeds of disposition equal to the amount received by the Resident Holder (excluding the amount of any interest awarded by a court) less the amount of any deemed dividend as described above. The dissenting Resident Holder will realize a capital gain (or capital loss) to the extent that the proceeds of disposition, net of any reasonable costs of disposition, exceed (or are less than) the adjusted cost base of the Resident Holder's Bluestone Shares.

A capital gain or capital loss realized by a dissenting Resident Holder will be treated in the same manner as described above under the subheading "Holders Resident in Canada - Capital Gains and Capital Losses".

Interest awarded by a court to a dissenting Resident Holder will be included in the holder's income for purposes of the Tax Act.

Resident Holders should consult their own tax advisors with respect to the Canadian federal income tax consequences of exercising their Dissent Rights.

Other Taxes

Capital gains realized (or deemed to have been realized) by individuals or a trust, other than certain specified trusts, may give rise to minimum tax under the Tax Act. Resident Holders that are individuals should consult their own tax advisors in this regard.

A Resident Holder that is, throughout the relevant taxation year, a "Canadian controlled private corporation" (as defined in the Tax Act) or, at any time in a relevant taxation year, a "substantive CCPC" (as defined in the Tax Act) may be liable to pay an additional tax (refundable in certain circumstances) on its "aggregate investment income", which is defined in the Tax Act to include interest income, net taxable capital gains, and dividends (including deemed dividends) that are not deductible in computing the Resident Holder's taxable income for the taxation year.

Offshore Investment Fund Property Rules

The Tax Act contains provisions (the "OIF Rules") which, in certain circumstances, may require a Resident Holder to include an amount in income in each taxation year in respect of the acquisition and holding of Aura Shares if (1) the value of such Aura Shares may reasonably be considered to be derived, directly or indirectly, primarily from portfolio investments in: (i) shares of the capital stock of one or more corporations, (ii) indebtedness or annuities, (iii) interests in one or more corporations, trusts, partnerships, organizations, funds or entities, (iv) commodities, (v) real estate, (vi) Canadian or foreign resource properties, (vii) currency of a country other than Canada, (viii) rights or options to acquire or dispose of any of the foregoing, or (ix) any combination of the foregoing, (collectively, the "Investment Assets"), and (2) it may reasonably be concluded that one of the main reasons for the Resident Holder acquiring, holding or having Aura Shares was to derive a benefit from portfolio investments in Investment Assets in such a manner that the taxes, if any, on the income, profits and gains from the Investment Assets for any particular year are significantly less than the tax that would have been applicable under Part I of the Tax Act if the income, profits and gains had been earned directly by the Resident Holder.


2024 Special Meeting of Securityholders

In making this determination, the OIF Rules provide that regard must be had to all of the circumstances, including (i) the nature, organization and operation of any non-resident entity, including Aura, and the form of, and the terms and conditions governing, the Resident Holder's interest in, or connection with, any such non-resident entity, (ii) the extent to which any income, profit and gains that may reasonably be considered to be earned or accrued, whether directly or indirectly, for the benefit of any such non-resident entity, including Aura, are subject to an income or profits tax that is significantly less than the income tax that would be applicable to such income, profits and gains if they were earned directly by the Resident Holder, and (iii) the extent to which any income, profits and gains of any such non-resident entity, including Aura, for any fiscal period are distributed in that or the immediately following fiscal period.

If applicable, the OIF Rules can result in a Resident Holder being required to include in its income for each taxation year in which such Resident Holder owns Aura Shares the amount, if any, by which (i) the total of all amounts each of which is the product obtained when the Resident Holder's "designated cost" (as defined in the Tax Act) of Aura Shares at the end of a month in the year is multiplied by 1/12 of the aggregate of the prescribed rate of interest for the period including that month plus two percentage points exceeds (ii) the Resident Holder's income for the year (other than a capital gain) in respect of Aura Shares determined without reference to the OIF Rules. Any amount required to be included in computing a Resident Holder's income under these provisions will be added to the adjusted cost base and the designated cost of the Aura Shares to the Resident Holder.

The CRA has taken the position that the term "portfolio investment" should be given a broad interpretation. If the term "portfolio investment" should be given a broad interpretation, and even if the value of the Aura Shares may reasonably be considered to be derived, directly or indirectly, primarily from portfolio investments in Investment Assets, the OIF Rules will apply only if it is reasonable to conclude that one of the main reasons for a Resident Holder acquiring, holding or having Aura Shares was to derive, either directly or indirectly, a benefit from Investment Assets in such a manner that the taxes, if any, on the income, profits and gains from such Investment Assets for any particular year are significantly less than the tax that would have been applicable under Part I of the Tax Act if the income, profits and gains had been earned directly by the Resident Holder.

The OIF Rules are complex and Resident Holders are urged to consult their own tax advisors regarding the application and consequences of the OIF Rules in their own particular circumstances.

Foreign Property Information Reporting

A Resident Holder who is a "specified Canadian entity" (as defined in the Tax Act) for a taxation year or a fiscal period and whose total "cost amount" of "specified foreign property" (each as defined in the Tax Act), including Aura Shares, at any time in the year or fiscal period exceeds $100,000 will be required to file an information return with the CRA for the taxation year or fiscal period disclosing certain prescribed information in respect of such property. Subject to certain exceptions, a taxpayer resident in Canada will be a "specified Canadian entity," as will certain partnerships. Penalties may apply where a Resident Holder fails to file the required information return in respect of such Resident Holder's "specified foreign property" (as defined in the Tax Act) on a timely basis in accordance with the Tax Act.


2024 Special Meeting of Securityholders

The foreign property reporting rules in the Tax Act are complex and this summary does not purport to address all circumstances in which reporting may be required by a Resident Holder. Resident Holders should consult their own tax advisors regarding compliance with these rules.

Holders Not Resident in Canada

The following portion of this summary is applicable to a Holder who: (i) has not been, is not, and is not deemed to be, resident in Canada for purposes of the Tax Act; and (ii) does not use or hold, and is not deemed to use or hold, Bluestone Shares, Aura Shares or CVRs in connection with carrying on a business in Canada (a "Non-Resident Holder"). Special rules, which are not discussed in this summary, may apply to a Non-Resident Holder that is an insurer carrying on business in Canada and elsewhere or that is an "authorized foreign bank" (as defined in the Tax Act). Non-Resident Holders should consult their own tax advisors with respect to the Arrangement.

Disposition or Exchange of Bluestone Shares and Subsequent Dispositions of Aura Shares and CVRs

Non-Resident Holders who exchange their Bluestone Shares under the Arrangement will generally not be subject to tax under the Tax Act on any capital gain realized on the exchange unless such Bluestone Shares are, or are deemed to be, "taxable Canadian property" (as defined in the Tax Act) of the Non-Resident Holder at the time of exchange and the gain is not exempt from tax pursuant to the terms of an applicable tax treaty or convention.

Similarly, any capital gain realized by a Non-Resident Holder on the disposition or deemed disposition of Aura Shares or CVRs will not be subject to tax under the Tax Act unless such Aura Shares or CVRs, respectively, are, or are deemed to be, taxable Canadian property of the Non-Resident Holder at the time of disposition and the gain is not exempt from tax pursuant to the terms of an applicable tax treaty or convention. It is not anticipated that the CVRs will constitute taxable Canadian property of Non-Resident Holders.

Generally, a Bluestone Share or an Aura Share will not constitute taxable Canadian property of a Non-Resident Holder at the time of disposition (including upon the exchange of the Bluestone Shares) provided that the particular share is listed on a "designated stock exchange" for the purposes of the Tax Act (which currently includes the TSX), unless at any time during the 60 month period immediately preceding the disposition or deemed disposition of the share the following two conditions are met concurrently:

(a) the Non-Resident Holder, persons with whom the Non-Resident Holder does not deal at arm's length, partnerships whose members include, either directly or indirectly through one or more partnerships, the Non-Resident Holder and/or persons with whom the Non-Resident Holder does not deal at arm's length, or any combination of the foregoing, owned 25% or more of the issued shares of any class or series of shares of the capital stock of Bluestone or Aura, as applicable; and

(b) the share derived more than 50% of its fair market value directly or indirectly from, or from any combination of, real or immovable property situated in Canada, "Canadian resource properties", "timber resource properties" (as those terms are defined in the Tax Act), or options in respect of, interests in, or, for civil law, rights in, any such property (whether or not such property exists).

Notwithstanding the foregoing, a Bluestone Share or Aura Share may be deemed to be "taxable Canadian property" in certain other circumstances. Non-Resident Holders should consult their own tax advisors in this regard.

A Non-Resident Holder's capital gain (or capital loss) in respect of a Bluestone Share or an Aura Share that constitutes or is deemed to constitute taxable Canadian property of a Non-Resident Holder (and is not "treaty-protected property" as defined in the Tax Act) will generally be computed in the manner described under the subheadings "Holders Resident in Canada - Disposition or Exchange of Bluestone Shares", "Holders Resident in Canada - Dispositions of Aura Shares" and "Holders Resident in Canada - Capital Gains and Capital Losses".


2024 Special Meeting of Securityholders

Non-Resident Holders who may hold shares as "taxable Canadian property" should consult their own tax advisors in this regard, including with respect to the potential Canadian income tax filing requirements of owning and disposing of such shares.

Dividends on Aura Shares

Dividends paid on Aura Shares to a Non-Resident Holder will not be subject to Canadian withholding tax or other income tax under the Tax Act.

Dissenting Non-Resident Holders

A Non-Resident Holder who, as a result of the exercise of Dissent Rights, is entitled to be paid the fair value of its Bluestone Shares by Bluestone will be deemed to have received a dividend equal to the amount, if any, by which the payment received for such Bluestone Shares (less the amount in respect of interest, if any, awarded by a court) exceeds the paid-up capital of such shares (as determined under the Tax Act).

Dividends deemed to be paid or credited to a dissenting Non-Resident Holder by Bluestone will be subject to Canadian withholding tax at the rate of 25% of the gross amount of the dividend unless such rate is reduced by the terms of an applicable income tax treaty or convention. For example, under the Canada-United States Tax Convention (1980), as amended (the "Canada-US Tax Treaty"), the rate of withholding tax on dividends paid or credited or deemed to be paid or credited to a Non-Resident Holder who is resident in the United States for purposes of the Canada-US Tax Treaty, is the beneficial holder of the dividend, and is fully entitled to benefits under the Canada-US Tax Treaty (a "U.S. Holder") is generally reduced to 15% of the gross amount of the dividend (or 5% in the case of a U.S. Holder that is a company beneficially owning at least 10% of such company's voting shares). The Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting of which Canada is a signatory, affects many of Canada's tax treaties (but not the Canada-US Tax Treaty), including the ability to claim benefits thereunder.

A Non-Resident Holder that is a dissenting Non-Resident Holder will not be subject to tax under the Tax Act on any capital gain realized on the disposition unless such Bluestone Shares are, or are deemed to be, "taxable Canadian property" (as defined in the Tax Act) of the Non-Resident Holder at the time of disposition and the Non-Resident Holder is not entitled to relief under an applicable income tax treaty or convention. The same general considerations apply as discussed above under the heading "Holders Not Resident in Canada - Disposition or Exchange of Bluestone Shares and Subsequent Dispositions of Aura Shares and CVRs" in determining whether a capital gain will be subject to tax under the Tax Act.

Any interest paid or credited to a dissenting Non-Resident Holder who deals at arm's length with Bluestone, Aura and the Purchaser for purposes of the Tax Act should not be subject to withholding tax under the Tax Act.

Non-Resident Holders should consult their own tax advisors with respect to the consequences of exercising their Dissent Rights.

Eligibility for Investment

Subject to the provisions of any particular plan, the Aura Shares, if issued on the date hereof, would be "qualified investments" under the Tax Act for trusts governed by "registered retirement savings plans", "registered retirement income funds", "registered education savings plans", "registered disability savings plans", "first home savings account", and "tax-free savings accounts" (collectively, "Registered Plans") and deferred profit sharing plans ("DPSPs") (as those terms are defined in the Tax Act), provided that the Aura Shares are listed on a "designated stock exchange" as defined in the Tax Act (which includes the TSX) or the Corporation otherwise qualifies as a "public corporation" other than a "mortgage investment corporation" (each as defined in the Tax Act).


2024 Special Meeting of Securityholders

Notwithstanding that the Aura Shares may be qualified investments at a particular time, the holder, annuitant or subscriber, as applicable (the "Controlling Individual"), of a Registered Plan will be subject to a penalty tax in respect of an Aura Share held in the Registered Plan if the share is a "prohibited investment" under the Tax Act. An Aura Share generally will not be a prohibited investment for a Registered Plan provided the Controlling Individual of the Registered Plan: (i) deals at arm's length with Aura for the purposes of the Tax Act; and (ii) does not have a "significant interest" (as defined in the Tax Act for purposes of the prohibited investment rules) in Aura. In addition, the Aura Shares will not be a prohibited investment if such shares are "excluded property" (as defined in the Tax Act for purposes of the prohibited investment rules) for the Registered Plan.

Persons who intend to hold Aura Shares in a Registered Plan or DPSP should consult their own tax advisors in regard to the application of these rules in their particular circumstances.

The CVRs will not be qualified investments under the Tax Act for a Registered Plan or DPSP. As a result, such trusts holding CVRs or, in certain cases, the annuitant, holder or subscriber thereof may be subject to penalty taxes as a result of the trust holding CVRs. Other negative tax consequences may also result. Resident Holders should consult their own tax advisors for advice as to any actions to be taken to avoid such adverse tax consequences.

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE ARRANGEMENT

The following summary describes certain U.S. federal income tax consequences generally applicable to U.S. Holders (as defined below) relating to (i) the exchange of Bluestone Shares for the Consideration pursuant to the Arrangement and (ii) the ownership and disposition of Aura Shares and CVRs received pursuant to the Arrangement. This summary is for general information purposes only and is not tax advice. This summary is based on the Code, U.S. Treasury regulations promulgated under the Code ("Treasury Regulations"), the Canada-US Tax Treaty, published rulings, administrative pronouncements and judicial decisions, all as in effect on the date hereof and all of which are subject to change or differing interpretations, possibly with retroactive effect. Any such change could affect the continuing validity of this summary. This summary addresses only U.S. Holders who hold their Bluestone Shares, Aura Shares and CVRs as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment) and does not address all of the tax consequences that may be relevant to U.S. Holders in light of their particular circumstances or to certain types of U.S. Holders subject to special treatment under the Code, including pass-through entities (including partnerships and S corporations for U.S. federal income tax purposes) and partners or investors who hold their Bluestone Shares through such entities, certain financial institutions, brokers, dealers or traders in securities or other persons that generally mark their securities to market for U.S. federal income tax purposes, insurance companies, expatriates, mutual funds, real estate investment trusts, regulated investment companies, cooperatives, tax-exempt organizations (including private foundations), retirement plans, controlled foreign corporations, passive foreign investment companies, persons who are subject to the alternative minimum tax, persons who hold their Bluestone Shares, Aura Shares or CVRs as part of a straddle, hedge, conversion, constructive sale, synthetic security, integrated investment, or other risk-reduction transaction for U.S. federal income tax purposes, persons that have a functional currency other than the U.S. dollar, persons that own or have owned, directly, indirectly or by attribution, 5% or more of the total combined voting power or value of all Bluestone Shares or who will own immediately following the Arrangement, directly, indirectly or by attribution, 5% or more of Aura, persons that hold Bluestone Shares (or after the Arrangement, Aura Shares or CVRs) in connection with a trade or business, permanent establishment or fixed base outside the United States, and persons who acquired their Bluestone Shares through the exercise of employee stock options, as compensation for services, or through a tax-qualified retirement plan. This summary does not address any U.S. federal estate, gift, or other non-income tax consequences, the effects of the Medicare contribution tax on net investment income, or any state, local, or non-U.S. tax consequences.

As used in this summary, the term "U.S. Holder" means a beneficial owner of Bluestone Shares participating in the Arrangement that, for U.S. federal income tax purposes, is: (i) an individual who is a citizen or resident of the United States; (ii) a corporation, or other entity classified as a corporation for U.S. federal income tax purposes, that is created or organized in or under the laws of the United States or any state thereof or the District of Columbia; (iii) an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) a trust if (A) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more "U.S. persons" (within the meaning of Section 7701(a)(30) of the Code) has the authority to control all substantial decisions of the trust or (B) the trust has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person.


2024 Special Meeting of Securityholders

If a partnership (including any entity or arrangement treated as a partnership for U.S. federal income tax purposes) exchanges Bluestone Shares for CVRs and Aura Shares and/or cash pursuant to the Arrangement, the tax treatment of a partner in the partnership will generally depend upon the status of the partner, the activities of the partnership, and certain determinations made at the partner level. The partnership and partners of the partnership holding Bluestone Shares are urged to consult their own tax advisors regarding the particular tax consequences of exchanging Bluestone Shares for CVRs and Aura Shares and/or cash pursuant to the Arrangement applicable to them.

For purposes of this summary, a "Non-U.S. Holder" means a beneficial owner of Bluestone Shares or Aura Shares, as the case may be, or CVRs, participating in the Arrangement or exercising Dissent Rights pursuant to the Arrangement, that is not a U.S. Holder for U.S. federal tax purposes.

This summary does not address the U.S. federal income tax consequences applicable to Non-U.S. Holders arising from the Arrangement or the ownership and disposition of Aura Shares or CVRs received pursuant to the Arrangement. Accordingly, Non-U.S. Holders are urged to consult their own tax advisors regarding all U.S. federal, U.S. state and local, and non-U.S. tax consequences (including the potential application and operation of any income tax treaties) relating to the Arrangement and the ownership and disposition of Aura Shares or CVRs received pursuant to the Arrangement.

Bluestone and Aura have not sought, and do not expect to seek, an opinion of legal counsel or ruling from the U.S. Internal Revenue Service (the "IRS") as to any U.S. federal income tax consequence described herein, and no assurance can be given that the IRS will not take a position contrary to the discussion below, or that a court will not sustain any challenge by the IRS in the event of litigation.

Holders are urged to consult their own tax advisors to determine the tax consequences to them of exchanging Bluestone Shares for CVRs and Aura Shares and/or cash pursuant to the Arrangement. 

U.S. Federal Income Tax Consequences of the Exchange of Bluestone Shares for CVRs and Aura Shares and/or Cash Consideration Pursuant to the Arrangement

The exchange of Bluestone Shares for the Consideration pursuant to the Arrangement will be a taxable transaction for U.S. federal income tax purposes. The amount of gain or loss a U.S. Holder recognizes, and the timing and potentially the character of a portion of such gain or loss, depends in part on the U.S. federal income tax treatment of the CVRs, with respect to which there is significant uncertainty. The installment method of reporting any gain attributable to the receipt of a CVR generally will not be available with respect to the disposition of Bluestone Shares pursuant to the Arrangement because Bluestone Shares are traded on an established securities market. Cash paid pursuant to the Arrangement and the CVRs will be paid in Canadian dollars. See "Foreign Currency Considerations" below. Special considerations may apply to a U.S. Holder who is subject to non-U.S. tax with respect to the Arrangement. See "Foreign Tax Credit" below.

There is no legal authority directly addressing the U.S. federal income tax treatment of the receipt of the CVRs in connection with the Arrangement or payments received on the CVRs. The receipt of the CVRs as part of the Arrangement consideration might be treated as an "open transaction" or as a "closed transaction" for U.S. federal income tax purposes, each discussed below, or in some other manner, and such questions are inherently factual in nature. Accordingly, U.S. Holders are urged to consult with their own tax advisors regarding this issue.


2024 Special Meeting of Securityholders

Pursuant to Treasury Regulations addressing contingent payment obligations that are analogous to the CVRs, if the fair market value of the CVRs is "reasonably ascertainable," a U.S. Holder should treat the transaction as a "closed transaction" and treat the fair market value of the CVRs as part of the consideration received in the Arrangement for purposes of determining gain or loss. On the other hand, if the fair market value of the CVRs could not be reasonably ascertained, a U.S. Holder should treat the transaction as an "open transaction" for purposes of determining gain or loss. These Treasury Regulations state that only in "rare and extraordinary" cases would the value of contingent payment obligations not be reasonably ascertainable. There is no authority directly addressing whether contingent payment rights with characteristics similar to the rights under a CVR should be treated as "open transactions" or "closed transactions," and such question is inherently factual in nature. The CVRs also may be treated as contract rights, debt instruments or deferred payment contract rights for U.S. federal income tax purposes, which would affect the amount, timing, and character of any gain, income or loss with respect to the CVRs. The discussion below does not address the tax consequences of such a characterization. Each U.S. Holder is urged to consult its own tax advisor with respect to the proper characterization of the receipt of, and payments made with respect to, a CVR.

The following sections discuss certain U.S. federal income tax consequences of the Arrangement if the exchange of Bluestone Shares for CVRs and Aura Shares and/or cash pursuant to the Arrangement is treated as an open transaction or, alternatively, as a closed transaction for U.S. federal income tax purposes. Under either "open" or "closed" transaction treatment, gain or loss generally will be determined separately for each block of Bluestone Shares (that is, Bluestone Shares acquired at the same cost in a single transaction) surrendered pursuant to the Arrangement.

Treatment as Open Transaction. If the transaction is treated as an "open transaction" for U.S. federal income tax purposes, a U.S. Holder would generally, subject to the PFIC rules discussed below, recognize gain or loss in an amount equal to the difference, if any, between (i) the amount of cash and the fair market value (determined as of the Effective Date, expressed in U.S. dollars) of Aura Shares received pursuant to the Arrangement and (ii) such U.S. Holder's adjusted U.S. federal income tax basis (expressed in U.S. dollars) in the Bluestone Shares surrendered in exchange therefor. However, a U.S. Holder may not be able to recognize loss for U.S. federal income tax purposes in connection with the Arrangement even if its adjusted U.S. federal income tax basis in its Bluestone Shares exceeds the fair market value of the cash and/or Aura Shares received pursuant to the Arrangement and instead may be required to defer recognition of loss (and the determination of the amount of such loss) until the U.S. Holder's right to receive further payments under the CVRs terminates (e.g., upon payment of the CVR Payment Amount in full, the CVR Termination Date passing or if the U.S. Holder abandons or disposes of its CVRs), as discussed below.

A U.S. Holder's initial U.S. federal income tax basis in Aura Shares received in the Arrangement would equal the fair market value of such Aura Shares as determined for U.S. federal income tax purposes. The holding period for such Aura Shares would begin on the day following the Effective Date.

The fair market value of the CVRs generally would not be treated as additional consideration for the Bluestone Shares at the time the CVRs are received pursuant to the Arrangement, and the U.S. Holder would have no U.S. federal income tax basis in the CVRs. Instead, the U.S. Holder would take payments under or with respect to the CVRs into account when made or deemed made in accordance with the U.S. Holder's regular method of accounting for U.S. federal income tax purposes. A portion of such payments may be treated as interest income under Section 483 of the Code (as discussed below under "Imputed Interest") and the balance, in general, would be treated as additional consideration for the disposition of the Bluestone Shares. Subject to the PFIC rules discussed below, the portion of payments on or with respect to the CVRs not treated as imputed interest under Section 483 of the Code (as discussed below under "Imputed Interest") will generally be treated as gain to the extent the sum of such payments (and all previous payments under the CVRs), together with the cash and/or Aura Shares received pursuant to the Arrangement, exceeds such U.S. Holder's adjusted U.S. federal income tax basis in the Bluestone Shares surrendered pursuant to the Arrangement. Subject to the imputed interest rules discussed below, a U.S. Holder that does not receive cash and/or Aura Shares pursuant to the Arrangement (including for this purpose any cash received as payments on or with respect to the CVRs) in an amount at least equal to such U.S. Holder's adjusted U.S. federal income tax basis in the Bluestone Shares surrendered pursuant to the Arrangement may be able to recognize a capital loss upon termination of the U.S. Holder's right to receive further payments under the CVR (e.g., upon payment of the CVR Payment Amount in full, the CVR Termination Date passing without achieving the CVR Payment Conditions or if the U.S. Holder abandons or disposes of its CVRs). Any such capital gain or loss will be long-term if the Bluestone Shares were held for more than one year prior to the Effective Date. The deductibility of capital losses is subject to significant limitations.


2024 Special Meeting of Securityholders

Treatment as Closed Transaction. If the receipt of the CVRs is treated as part of a closed transaction for U.S. federal income tax purposes, then a U.S. Holder would generally, subject to the PFIC rules discussed below, recognize capital gain or loss in an amount equal to the difference, if any, between (i) the amount of cash and the fair market value (determined as of the Effective Date, expressed in U.S. dollars) of Aura Shares and CVRs received pursuant to the Arrangement and (ii) such U.S. Holder's adjusted U.S. federal income tax basis (expressed in U.S. dollars) in the Bluestone Shares exchanged therefor. The proper method to determine the fair market value of a CVR is not clear. Any capital gain or loss recognized will be long-term capital gain or loss if the Holder's holding period for Bluestone Shares exceeds one year. The deductibility of capital losses is subject to significant limitations.

A U.S. Holder's initial U.S. federal income tax basis in Aura Shares and CVRs received in the Arrangement would equal the fair market value of such Aura Shares and CVRs, respectively, as determined for U.S. federal income tax purposes. The holding period for such Aura Shares and CVRs would begin on the day following the Effective Date.

There is no authority directly addressing the U.S. federal income tax treatment of receiving payments on or with respect to the CVRs and, therefore, the amount, timing and character of any gain, income or loss with respect to the CVRs would be uncertain. For example, if a payment is made with respect to a CVR, it could be treated as a payment with respect to a sale or exchange of a capital asset or as giving rise to ordinary income. It is unclear how a U.S. Holder of the CVRs would recover its adjusted tax basis with respect to payments thereon. It is also possible that, were the payment to be treated as being made with respect to the sale of a capital asset, a portion of such payment may constitute imputed interest under Section 483 of the Code (as described below under "Imputed Interest").

Imputed Interest. A portion of the payments made with respect to a CVR may be treated as imputed interest, which would be ordinary income to the U.S. Holder of a CVR. The portion of any payment made with respect to a CVR treated as imputed interest under Section 483 of the Code will be determined at the time such payment is made and generally should equal the excess of: (i) the amount of the payment in respect of the CVRs; over (ii) the present value of such amount as of the Effective Date, as the case may be, calculated using the applicable federal rate published by the IRS as the discount rate. A U.S. Holder must include in its taxable income interest imputed pursuant to Section 483 of the Code using such U.S. Holder's regular method of accounting for U.S. federal income tax purposes.

Tax Consequences of the Arrangement if Bluestone is Classified as a PFIC

A U.S. Holder of Bluestone Shares could be subject to special, adverse tax rules in respect of the Arrangement if Bluestone were classified as a "passive foreign investment company" within the meaning of Section 1297 of the Code (a "PFIC") for any tax year during which such U.S. Holder holds or held Bluestone Shares.

A non-U.S. corporation is a PFIC for each tax year in which either (i) 75% or more of its gross income is passive income (as defined for U.S. federal income tax purposes) or (ii) 50% or more of its assets (by value) either produce passive income or are held for the production of passive income, based on the quarterly average of the fair market value of such assets. For purposes of the PFIC provisions, "gross income" generally includes all sales revenues less cost of goods sold, plus income from other investments and from incidental or outside operations or sources. For purposes of the PFIC provisions, "passive income" generally includes dividends, interest, certain royalties and rents, certain gains from the sale of stock and securities, and certain gains from commodities transactions. In determining whether or not it is a PFIC, a non-U.S. corporation is required to take into account its pro rata portion of the income and assets of each corporation in which it owns, directly or indirectly, at least a 25% interest (by value). Active business gains arising from the sale of commodities generally are excluded from passive income if substantially all (85% or more) of a foreign corporation's gross income arises from commodities that are stock in trade or inventory, depreciable property used in a trade or business, or supplies regularly used or consumed in a trade or business and certain other requirements are satisfied.


2024 Special Meeting of Securityholders

Based on current business plans and financial expectations, Bluestone expects to be classified as a PFIC during its tax year which includes the Effective Date, and believes it has been a PFIC in prior tax years. No opinion of legal counsel or ruling from the IRS concerning Bluestone's status as a PFIC has been obtained or is currently planned to be requested. PFIC classification is factual in nature, and generally cannot be determined until the close of the tax year in question. Additionally, the analysis depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. Consequently, there can be no assurances regarding the PFIC status of Bluestone during its tax year which includes the Effective Date or any prior tax year.

If Bluestone is classified as a PFIC for any tax year during which a U.S. Holder has held Bluestone Shares, special rules may increase such U.S. Holder's U.S. federal income tax liability with respect to the Arrangement. U.S. Holders are urged to consult their own tax advisors regarding the U.S. federal income tax consequences of holding an interest in a PFIC.

Under the default PFIC rules:

 any gain on the exchange of Bluestone Shares pursuant to the Arrangement will be allocated ratably over such U.S. Holder's holding period for the Bluestone Shares;

 the amounts allocated to the current tax year and to any tax year prior to the first year in which Bluestone was a PFIC will be taxed as ordinary income in the current year;

 the amounts allocated to each of the other tax years in such U.S. Holder's holding period for the Bluestone Shares ("prior PFIC years") will be subject to tax as ordinary income at the highest rate of tax in effect for the applicable class of taxpayer for that year; and

 an interest charge for a deemed deferral benefit will be imposed with respect to the resulting tax attributable to each of the prior PFIC years, which interest charge is not deductible by non-corporate U.S. Holders.

A U.S. Holder that has made a mark-to-market election under Section 1296 of the Code (a "Mark-to-Market Election") or a timely and effective election to treat Bluestone as a "qualified electing fund" (a "QEF" and such an election a "QEF Election") under Section 1295 of the Code may mitigate or avoid the PFIC consequences described above with respect to the Arrangement. U.S. Holders with a Mark-to-Market Election or a QEF Election in place are urged to consult their own tax advisors as to the impact to them of Bluestone being treated as a PFIC.

U.S. Holders are urged to consult their own tax advisors regarding the potential application of the PFIC rules to the receipt of Aura Shares pursuant to the Arrangement. Additional information regarding the PFIC rules is discussed under "Passive Foreign Investment Company Rules Relating to the Ownership of Aura Shares" below.

U.S. Federal Income Tax Consequences of Exercising Dissent Rights Pursuant to the Arrangement

A U.S. Holder of Bluestone Shares that exercises Dissent Rights in the Arrangement and is paid cash in exchange for all of its Bluestone Shares generally will recognize gain or loss in an amount equal to the difference, if any, between (i) the amount of cash received by such U.S. Holder in exchange for Bluestone Shares (other than amounts, if any, that are or are deemed to be interest for U.S. federal income tax purposes, which amounts will be taxed as ordinary income) and (ii) the adjusted tax basis of such U.S. Holder in such Bluestone Shares surrendered. Subject to the PFIC rules discussed above, such gain or loss would be long-term capital gain or loss if the U.S. Holder's holding period for such Bluestone Shares were more than one year at the Effective Date. Preferential tax rates for long-term capital gains are generally applicable to a U.S. Holder that is an individual, estate or trust. The deductibility of capital losses is subject to significant limitations. If Bluestone has been a PFIC at any time during which a U.S. Holder has held Bluestone Shares, then any gain from the exercise of Dissent Rights will be taxable in the manner described above under "Tax Consequences of the Arrangement if Bluestone Is Classified as a PFIC."


2024 Special Meeting of Securityholders

U.S. Federal Income Tax Consequences of the Ownership and Disposition of Aura Shares

Distributions on Aura Shares

Subject to the PFIC rules discussed below, a U.S. Holder that receives a distribution, including a constructive distribution, with respect to an Aura Share will be required to include the amount of such distribution in gross income as a dividend (without reduction for any tax withheld from such distribution) to the extent of the current or accumulated "earnings and profits" of Aura, as computed for U.S. federal income tax purposes. Aura does not intend to maintain the calculations of earnings and profits in accordance with U.S. federal income tax principles, and each U.S. Holder should therefore assume that any distribution by Aura with respect to Aura Shares will constitute dividend income. If Aura Shares are readily tradeable on an established securities market in the United States, then, subject to applicable limitations, dividends paid by Aura to non-corporate U.S. Holders, including individuals, generally will be eligible for the preferential tax rates applicable to long-term capital gains, provided that certain holding period and other conditions with respect to their Aura Shares are satisfied, including that Aura not be classified as a PFIC in the tax year of distribution or in the preceding tax year. If a U.S. Holder is not eligible for the preferential tax rates discussed above, a dividend paid by Aura to a U.S. Holder generally will be taxed at ordinary income rates. The dividend rules are complex, and each U.S. Holder is urged to consult its own tax advisor regarding the application of such rules.

Sale or Other Taxable Disposition of Aura Shares

Subject to the PFIC rules discussed below, a U.S. Holder that sells or otherwise disposes of Aura Shares in a taxable disposition will recognize gain or loss in an amount equal to the difference, if any, between the amount realized on such sale or other taxable disposition and the U.S. Holder's adjusted tax basis in such shares. Any such gain or loss will be long-term capital gain or loss if the U.S. Holder's holding period for the applicable Aura Shares is more than one year at the time of the sale or other disposition. A U.S. Holder's holding period for an Aura Share received pursuant to the Arrangement would begin on the day following the Effective Date. Preferential tax rates for long-term capital gains are generally applicable to a U.S. Holder that is an individual, estate, or trust. There is no preferential tax rate for long-term capital gains of a U.S. Holder that is a corporation. Deductions for capital losses are subject to significant limitations. Any such gain or loss recognized by a U.S. Holder generally will be treated as U.S.-source income for U.S. foreign tax credit purposes, although special rules apply to U.S. Holders who have a fixed place of business outside the United States to which the gain is attributable. Special considerations may apply to a U.S. Holder who receives foreign currency in connection with a sale or other taxable disposition of Aura Shares. See "Foreign Tax Credit" and "Foreign Currency Considerations" below.

Passive Foreign Investment Company Rules Relating to the Ownership of Aura Shares

If Aura is considered a PFIC at any time during a U.S. Holder's holding period, then certain different and potentially adverse tax consequences would apply to such U.S. Holder's acquisition, ownership and disposition of Aura Shares.

Aura generally will be a PFIC for a tax year if it satisfies the income test and asset test described above under "Tax Consequences of the Arrangement if Bluestone Is Classified as a PFIC." Based on current business plans and financial projections, Aura does not expect to be classified as a PFIC for its tax year which includes the day after the Effective Date. No opinion of legal counsel or ruling from the IRS concerning Aura's status as a PFIC has been obtained or is currently planned to be requested. The determination of whether Aura was, or will be, a PFIC for a tax year depends, in part, on the application of complex U.S. federal income tax rules, which are subject to differing interpretations. In addition, whether Aura will be a PFIC for any tax year depends on the assets and income of Aura over the course of each such tax year and, as a result, cannot be predicted with certainty as of the date of this Circular. Accordingly, there can be no assurance that the IRS will not challenge any determination made by Aura concerning its PFIC status or that Aura was not, or will not be, a PFIC for any tax year.

If Aura were classified as a PFIC in any taxable year during which a U.S. Holder owns Aura Shares, a U.S. Holder would be subject to the default PFIC rules described above under "Tax Consequences of the Arrangement if Bluestone is Classified as a PFIC" with respect to (a) any gain recognized on the sale or other taxable disposition of Aura Shares and (b) any excess distribution paid on Aura Shares. A distribution generally will be an "excess distribution" to the extent that such distribution (together with all other distributions received in the same taxable year) exceeds 125% of the average distributions received during the three preceding taxable years (or during a U.S. Holder's holding period for the Aura Shares, if shorter).


2024 Special Meeting of Securityholders

In addition, if Aura were classified as a PFIC and owns shares of another foreign corporation that also is a PFIC (a "Subsidiary PFIC"), under certain indirect ownership rules, a disposition by Aura of the shares of such other foreign corporation or a distribution received by Aura from such other foreign corporation generally will be treated as an indirect disposition by a U.S. Holder or an indirect distribution received by a U.S. Holder, subject to the rules of Section 1291 of the Code discussed above. To the extent that gain recognized on the actual disposition by a U.S. Holder of Aura Shares or income recognized by a U.S. Holder on an actual distribution received on the Aura Shares was previously subject to U.S. federal income tax under these indirect ownership rules, such amount generally will not be subject to U.S. federal income tax.

If Aura were classified as a PFIC for any taxable year during which a U.S. Holder holds Aura Shares, Aura will continue to be treated as a PFIC with respect to such U.S. Holder, regardless of whether Aura ceases to be a PFIC in a subsequent taxable year, unless the U.S. Holder makes a "purging" election that requires the U.S. Holder to recognize gain (which will be taxed under the default PFIC rules discussed above) as if such Aura Shares were sold on the last day of the last taxable year for which Aura was a PFIC.

If Aura were a PFIC for the taxable year in which a dividend is paid or in the preceding taxable year, such dividend would not be eligible for the preferential tax rates applicable to qualified dividends. Special rules also apply to foreign tax credits that a U.S. Holder may claim on a distribution from a PFIC.

If Aura were determined to be a PFIC at any time during which a U.S. Holder held (or is deemed to hold) Aura Shares, the U.S. Holder may mitigate some of the U.S. federal income tax consequences of the acquisition, ownership, and disposition of Aura Shares by making a QEF Election or a Mark-to-Market Election. A QEF election will not be available, however, if Aura does not provide the information necessary to make such an election. Aura does not expect to provide the information necessary to make a QEF election, and thus, a QEF Election is not expected to be available. A Mark-to-Market Election is available in limited circumstances and must be made in a timely manner. U.S. Holders are urged to consult their own tax advisors regarding the Mark-to-Market Election Rules.

Additional U.S. Federal Tax Considerations

Foreign Tax Credit

A U.S. Holder that pays (whether directly or through withholding) non-U.S. income tax in connection with the Arrangement or in connection with the ownership or disposition of Aura Shares or CVRs may be entitled, at the election of such U.S. Holder, to receive either a deduction or a credit for such non-U.S. income tax paid. Subject to certain limitations, a credit will generally reduce a U.S. Holder's U.S. federal income tax liability on a dollar-for-dollar basis, whereas a deduction will reduce a U.S. Holder's income subject to U.S. federal income tax. This election is made on a year-by-year basis and applies to all creditable non-U.S. taxes paid (whether directly or through withholding) by a U.S. Holder during a tax year.

Complex limitations apply to the foreign tax credit, including the general limitation that the credit cannot exceed the proportionate share of a U.S. Holder's U.S. federal income tax liability that such U.S. Holder's "foreign source" taxable income bears to such U.S. Holder's worldwide taxable income. In applying this limitation, a U.S. Holder's various items of income and deduction must be classified, under complex rules, as either "foreign source" or "U.S. source." Generally, dividends paid by a non-U.S. corporation should be treated as foreign source for this purpose, and gains recognized on the sale of stock of a non-U.S. corporation by a U.S. Holder should be treated as U.S. source for this purpose, except as otherwise provided in an applicable income tax treaty, and if an election is properly made under the Code. However, the amount of a distribution with respect to Aura Shares that is treated as a "dividend" may be lower for U.S. federal income tax purposes than it is for Canadian federal income tax purposes, resulting in a reduced foreign tax credit allowance to a U.S. Holder. In addition, this limitation is calculated separately with respect to specific categories of income. The foreign tax credit rules are complex, and each U.S. Holder is urged to consult its own tax advisor regarding the foreign tax credit rules.


2024 Special Meeting of Securityholders

Foreign Currency Considerations

The amount of any distribution or proceeds paid in non-U.S. currency to a U.S. Holder in connection with the ownership of Aura Shares, or on the sale, exchange, or other taxable disposition of Aura Shares, or any Canadian dollars received in connection with the Arrangement, will generally be included in the gross income of a U.S. Holder as translated into U.S. dollars calculated by reference to the exchange rate prevailing on the date of actual or constructive receipt of such amount, regardless of whether the Canadian dollars (or other non-U.S. currency) are converted into U.S. dollars at that time. If the Canadian dollars (or other non-U.S. currency) received are not converted into U.S. dollars on the date of receipt, a U.S. Holder will have a basis in the Canadian dollars or other non-U.S. currency equal to the U.S. dollar value thereof on the date of receipt. Any U.S. Holder that receives payment in Canadian dollars or other non-U.S. currency and engages in a subsequent conversion or other disposition of the Canadian dollars or other non-U.S. currency may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss, and generally would be U.S.-source income or loss for foreign tax credit purposes. Different rules apply to U.S. Holders that use the accrual method. Each U.S. Holder is urged to consult its own tax advisor regarding the U.S. federal income tax consequences of receiving, owning, and disposing of Canadian dollars or other non-U.S. currency.

Information Reporting, Backup Withholding, and Other Reporting Requirements

Under U.S. federal income tax law and the Treasury Regulations, certain categories of U.S. Holders must file information returns with respect to their investment in, or involvement with, a foreign corporation. A U.S. Holder that owns Bluestone Shares or Aura Shares during any taxable year in which Bluestone or Aura, respectively, is treated as a PFIC or controlled foreign corporation with respect to such U.S. Holder generally would be required to file statements with respect to such shares on IRS Form 8621 or 5471 with their U.S. federal income tax returns. Failure to file such statements may result in the extension of the period of limitations on assessment and collection of U.S. federal income taxes.

Certain U.S. Holders who are individuals must report information relating to an interest in "specified foreign financial assets," including shares issued by a non-U.S. corporation, for any year in which the aggregate value of all specified foreign financial assets exceeds US$50,000, subject to certain exceptions (including an exception for ordinary shares held in custodial accounts maintained with a U.S. financial institution). Substantial penalties may be imposed for a failure to disclose such information. Each U.S. Holder is urged to consult its own tax advisor regarding the effect, if any, of these additional reporting requirements on their ownership and disposition of Aura Shares.

Payments made within the United States or by U.S. payors or middlemen of (i) distributions on Aura Shares, (ii) proceeds arising from the sale or other taxable disposition of Aura Shares, or (iii) payments received in connection with the Arrangement (including, but not limited to, Bluestone Shareholders who exercise Dissent Rights), may be subject to information reporting and backup withholding (currently at a 24% rate). Payments of distributions on, or the proceeds from the sale or other disposition of, Aura Shares to or through a foreign office of a broker generally will not be subject to backup withholding, although information reporting may apply to those payments in certain circumstances. Backup withholding generally will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and certifies that he, she, or it is not subject to backup withholding on IRS Form W-9 (or substitute form), or is otherwise exempt from backup withholding.

Backup withholding is not an additional tax. Any amounts withheld from a payment to a holder under the backup withholding rules may be credited against the holder's U.S. federal income tax liability, and a holder may obtain a refund of any excess amounts withheld by filing the appropriate claim for refund with the IRS in a timely manner and furnishing any required information. Each U.S. Holder is urged to consult its own tax advisor regarding the information reporting and backup withholding rules in their particular circumstances and the availability of and procedures for obtaining an exemption from backup withholding.


2024 Special Meeting of Securityholders

The discussion of reporting and withholding requirements set forth above is not intended to constitute an exhaustive description of all reporting requirements that may apply to a U.S. Holder. A failure to satisfy certain reporting requirements may result in an extension of the time period during which the IRS can assess a tax, and under certain circumstances, such an extension may apply to assessments of amounts unrelated to any unsatisfied reporting requirement. Each U.S. Holder is urged to consult its own tax advisor regarding applicable reporting requirements and the information reporting and backup withholding rules.

The foregoing discussion of certain U.S. federal income tax considerations is for general information only and is not intended to constitute a complete analysis of all tax consequences arising from the receipt of CVRs, Aura Shares and/or Cash Consideration pursuant to the Arrangement and the ownership and disposition of such Aura Shares and/or CVRs. U.S. Holders are urged to consult their own tax advisors concerning the tax consequences applicable to their particular situations.

2. Mineral Reserves are the economic portion of the Measured and Indicated Mineral Resources. Mineral Reserve estimates include mining dilution and mining recovery. Mining dilution and recovery factors vary with specific reserve sources and are influenced by several factors including deposit type, deposit shape and mining methods.

3. The estimate of Mineral Reserves may be materially affected by environmental, permitting, legal, marketing, or other relevant issues.

4. The disclosure of the Mineral Reserve estimates and related scientific and technical information has been prepared under the supervision or is approved by Bob Dowdell C.Eng. (Dowdell Mining Limited) as a Qualified Person for Aranzazu and Farshid Ghazanfari, P.Geo as a Qualified Person for San Andres, Almas Mine and EPP (excluding Nosde and Lavrinha Mines).

6. The Qualified Person for the Borborema Reserve Estimate is Bruno Yoshida Tomaselli, B.Sc., FAusIMM, an employee of Deswik.

7. The NSR cut-off US$63/t is based on the total predicted operating cost in Aranzazu.

8. Ore NSR values have been calculated using 4.00 US$/lb for copper, 1,800 US$/oz for gold and 22 US$/oz for silver and 2023 operation performance for metallurgical recoveries of 91.3% for copper, 79.5% for gold, 62.8% for silver and 64.7% for arsenic, resulting in the following formula: NSR ($/t) = (Cu% x US$65.866) + (Au g/t x US$41.292) + (Ag g/t x US$0.379). Dilution was applied in the in the form of planned and unplanned dilution from hanging wall and footwall end-wall. Dilution from backfill (for secondary stopes) was also included. All dilution material was assumed at zero grades. Total dilution is approximately 21%. Mining recoveries of 90% were applied to the stopes and ore development sill cuts respectively. All assumption are related to Aranzazu.

9. Mineral Reserves are calculated using pit designs, which have been optimized using only Measured and Indicated Resources at US$1,700/oz. gold price in San Andres.

10. Mineral Reserves have been estimated at a cut-off grade of 0.23 g/t for oxide material and 0.30 g/t for mixed material, with dilution of 5% and mining recovery of 95% in San Andres.

On May 22, 2024, Aura announced its acquisition, through its wholly owned subsidiary, of the right to explore the Pé Quente and Pezão Projects (the "Pé Quente Projects") in the State of Mato Grosso, Brazil. The Pé Quente Projects consist of a total of 6 mineral rights and are located in the geological setting of Alta Floresta Gold Province and are within a 50 km radius of Aura's Matupá Project, with a feasibility study published on November 18, 2022. Aura announced its intention to invest approximately U$1.6M in 13,000 meters of drilling over the following 12-month period with a focus on infill drilling and possible extensions aiming to confirm and validate the mineralization continuity and grades.

On June 7, 2024, Aura announced the approval of a dividend of US$0.35 per Aura Share, totaling approximately US$25.4 million. This dividend was above the minimum foreseen in Aura's dividend policy and is in respect of and is based on Aura's expected financial results for the six months ending June 30, 2024. Shareholders of record on June 20, 2024, received the dividend in US dollars, while holders of the Company's Brazilian Depositary Receipts ("BDRs") received the Brazilian Reais equivalent.

(ii) each other person who beneficially owns shares registered in the Bluestone Shareholder's name and on whose behalf the Bluestone Shareholder is providing a waiver, and

(b) identify in each waiver the person on whose behalf the waiver is made.

APPENDIX I
COMPARISON OF RELEVANT LAWS

In this Appendix I - "Comparison of Relevant Laws", unless there is something in the subject matter or context inconsistent therewith, capitalized terms have the meanings ascribed to those terms in the "Glossary of Terms" as set out in the accompanying Circular.

The following is a summary of certain differences between the BCBCA and the BVI Business Companies Act (BVIBCA), but it is not intended to be a comprehensive review of the two statutes. References should be made to the full text of both statutes and the regulations thereunder for particulars of any differences between them, and Shareholders should consult their legal or other professional advisors with regard to all of the implications of the arrangements which may be of importance to them.

Charter Documents

Under the BCBCA, the charter documents consist of a "notice of articles", which sets forth, among other things, the name of the company, a description of the company's authorized share structure, the mailing address and delivery address of the company's registered office and the company's records office, and the full names of, and the prescribed addresses for, each of the directors of the company, and "articles" which set rules for the company's conduct. The notice of articles is filed with the Registrar of Companies, and the articles are filed only in the company's minute book which is maintained at the company's records office.

Under the BVIBCA, the charter documents consist of a "memorandum", which sets forth, among other things, the name of the company, the maximum number of shares that the company may issue, details of any classes of shares and any restrictions to the company's business activities, and "articles" which sets out more detailed rules regarding the company's internal management. Both of the memorandum and the articles must be filed at the BVI Registrar of Corporate Affairs (BVI Registrar). The Memorandum and Articles are collectively referred to as the MAA. Many of the provisions of the BVIBCA that would otherwise apply to a company are made subject to permitted variation as may be contained within the MAA of the company.

Sale of Business or Assets

Under the BCBCA, a company may sell, lease or otherwise dispose of all of substantially all of its undertaking only if it does so in the ordinary course of its business or it has been authorized to do so by a special resolution. Under the BCBCA, a special resolution is a resolution passed at a general meeting of shareholders where the majority of the votes cast in favour of the resolution constitutes at least a "special majority", which means the majority of votes that the company's articles specify is required for a company to pass a special resolution at a general meeting, if such specified majority is at least ⅔ and not more than ¾ of the votes cast on the resolution. Bluestone's articles specify that a "special majority" is ⅔ of the votes cast on the resolution.

The BVIBCA (Section 175) provides that, subject to the memorandum or articles of a company, any sale, transfer, lease, exchange or other disposition, other than a mortgage, charge or other encumbrance or the enforcement thereof, of more than 50 per cent in value of the assets of the company, if not made in the usual or regular course of the business carried on by the company, must be approved by a resolution of members. The BVIBCA contains no other specific restrictions on the power of directors to dispose of assets of a company. Aura's MAA have disapplied Section 175 of the BVIBCA.

Amendments to the Charter Documents of a Corporation

Alterations to the articles of a company under the BCBCA will be effected by the type of resolution specified in the company's articles, which, in the case of Bluestone, for many alterations, including a change of name or a share consolidation or share split, provides for approval solely by way of a resolution of the directors. In the absence of anything in the articles, Bluestone's articles require an ordinary resolution of the shareholders to be passed. An ordinary resolution means a resolution passed at a general meeting by a simple majority of the votes cast by the shareholders voting shares at the meeting. Bluestone's articles provide that any alteration of the special rights and restrictions attached to issued shares requires shareholder approval by a special resolution of the holders of the class or series of shares affected. A proposed amalgamation requires shareholders to approve adoption of the amalgamation agreement by a special resolution, and a proposed continuation of a company out of British Columbia must also be authorized by way of a special resolution.


The BVIBCA provides that changes to the MAA may be made by a resolution of the shareholders or, if authorised pursuant to the articles of association of the company, a resolution of directors subject to the following restrictions. The directors shall not have the power to amend the memorandum and articles of association: (a) to restrict the rights or powers of the shareholders to amend the memorandum or articles; (b) to change the percentage of shareholders required to pass a resolution to amend the memorandum or articles; or (c) in circumstances where the memorandum or articles cannot be amended by the shareholders.

Aura's MAA provides that Aura may amend the Articles by resolution of directors, with such amendment to be approved by a resolution of shareholders at the next meeting of shareholders, save that no amendment may be made by resolution of directors: (a) to restrict the rights or powers of the shareholders to amend this Memorandum or the Articles; (b) to change the percentage of shareholders required to pass a special resolution of shareholders or a resolution of shareholders to amend this Memorandum or the Articles; (c) to increase or decrease the number of directors or the minimum or maximum number of directors; (d) to add, change or remove restriction on the issue, transfer or ownership of shares; (e) in circumstances where this Memorandum or the Articles cannot be amended by the Shareholders; or (f) to Clause 8 (Amendment of the Memorandum and the Articles) of the Memorandum.

Rights of Dissent and Appraisal

The BCBCA provides that a registered shareholder of a company who dissents from certain actions being taken by a company may exercise a right of dissent and require the company to purchase the shares held by such shareholder at the fair value of such shares. The dissent right is applicable where the company proposes to:

(a) alter the articles to alter restrictions on the powers of the company or on the business the company is permitted to carry on;

(b) adopt an amalgamation agreement;

(c) approve an amalgamation under Division 4 of Part 9 of the BCBCA;

(d) approve an arrangement, the terms of which arrangement permit dissent;

(e) authorize or ratify the sale, lease or other disposition of all or substantially all of the company's undertaking; or

(f) authorize the continuation of the company into a jurisdiction other than British Columbia.

In certain circumstances, shareholders may also be entitled to dissent in respect of a resolution if dissent is authorized by such resolution, or if permitted by court order.

The BVIBCA provides that any shareholder is entitled to payment of the fair value of their shares upon dissenting from any of the following:

(a) a merger;

(b) a consolidation;

(c) any sale, transfer, lease, exchange or other disposition of more than 50 per cent in value of the assets or business of the company if not made in the usual or regular course of the business carried on by the company but not including:

(i) a disposition pursuant to an order of the court having jurisdiction in the matter;


(ii) a disposition for money on terms requiring all or substantially all net proceeds to be distributed to the members in accordance with their respective interest within one year after the date of disposition; or

(iii) a transfer pursuant to the power of the directors to transfer assets for the protection thereof;

(iv) a redemption of 10 per cent, or fewer of the issued shares of the company required by the holders of 90 percent, or more of the shares of the company pursuant to the terms of the BVIBCA; and

(v) an arrangement, if permitted by the court.

Aura's MAA provides for additional shareholder dissent rights as follows: In addition to the dissent rights provided under section 179 of the Act, a shareholder is entitled to dissent (in the manner provided for in section 179 of the BVIBCA) and be paid fair value for the shares held by that shareholder if Aura purports to resolve to:

(a) amend its Memorandum or Articles to add, change or remove any provisions restricting or constraining the issue, transfer or ownership of shares of Aura of a class held by such shareholder;

(b) amend its Memorandum or Articles to add, change or remove any restriction on the business or businesses that Aura may carry on or upon the powers that Aura may exercise;

(c) be continued under the laws of another jurisdiction;

(d) sell, lease or exchange all or substantially all of its property other than in the ordinary course of business of Aura; or

(e) carry out a Going-Private Transaction or a Squeeze-Out Transaction.

Aura's MAA define a "Squeeze-Out Transaction" and a "Going-Private Transaction" as having the meaning ascribed thereto in the Canada Business Corporations Act.

Oppression Remedies

Under the BCBCA, a shareholder of a BC company (including a beneficial owner of a share of the company) and any other person whom the Supreme Court of British Columbia (the "Court") considers to be an appropriate person to make an application, may apply to the Court for an order that (a) the affairs of the company are being or have been conducted, or that the powers of the directors are being or have been exercised, in a manner oppressive to one or more of the shareholders, including the applicant, or (b) that some act of the company has been done or is threatened, or that some resolution of the shareholders or of the shareholders holding shares of a class or series of shares has been passed or is proposed, that is unfairly prejudicial to one or more of the shareholders, including the applicant. Under the BCBCA, the applicant must bring the application in a timely manner and the Court may make an order in respect of the complaint if it is satisfied that the application was brought by the shareholder in a timely manner. On an application, the Court may, with a view to remedying or bringing to an end the matters complained of, make any interim or final order it considers appropriate, including an order prohibiting any act proposed by the company. Under the BCBCA, if there are reasonable grounds for believing that the company is insolvent, or the payment to a successful applicant in an oppression claim of the full amount payable under the Court order would render the company insolvent, the company must pay to the person as much of the amount payable as is possible without rendering the company insolvent and pay the balance of the amount as soon as the company is able to do so without rendering the company insolvent.

Under the BVIBCA, a shareholder who considers that the affairs of the company have been, are being, or are likely to be, conducted in a manner that is or has been oppressive, unfairly discriminatory, or unfairly prejudicial to them in that capacity, may apply to the court for an order under section 184I of the BVIBCA. If the court decides it Is just and equitable to do so, it may make one of the following orders:

(a) in the case of a shareholder, requiring the company or any other person to acquire the shareholder's shares;


(b) requiring the company or any other person to pay compensation to the member;

(c) regulating the future conduct of the company's affairs;

(d) amending the memorandum or articles of the company;

(e) appointing a receiver of the company;

(f) appointing a liquidator of the company under section 159(1) of the Insolvency Act on the grounds specified in section 162(1)(b) of that Act;

(g) directing the rectification of the records of the company; and

(h) setting aside any decision made or action taken by the company or its directors in breach of the BVIBCA or the memorandum or articles of the company.

Shareholder Derivative Actions

Under the BCBCA, a shareholder of a BC company (including a beneficial owner of a share of the company and any other person whom the Court considers to be an appropriate person to make an application), or a director of a company may, with leave of the Court, prosecute a legal proceeding in the name and on behalf of the company (a) to enforce a right, duty or obligation owed to the company that could be enforced by the company itself, or (b) to obtain damages for any breach of a right, duty or obligation referred to in paragraph (a). An applicant may also, with leave of the Court, in the name of and on behalf of a company, defend a legal proceeding brought against the company.

The Court may grant leave on terms it considers appropriate, if:

(a) the complainant has made reasonable efforts to cause the directors of the company to prosecute or defend the legal proceeding;

(b) notice of the application for leave has been given to the company and to any other person the Court may order;

(c) the complainant is acting in good faith; and

(d) it appears to the Court that it is in the best interests of the company for the legal proceeding to be prosecuted or defended.

Under the BVIBCA a shareholder of a BVI business company may, with leave of the BVI court, bring procedures or intervene in proceedings in the name of a BVI business company in certain circumstances. The BVI court may only grant leave to bring a derivative action where it is satisfied that:

(a) the BVI business company does not intend to bring, diligently continue or defend or discontinue proceedings; and

(b) it is in the interests of the BVI business company that the conduct of the proceedings should not be left to the directors or to the determination of the shareholders as a whole.

When considering whether to grant leave, the BVI court must take the following matters into account:

(a) whether the shareholder is acting in good faith;

(b) whether the derivative action is in the interests of the BVI business company, taking account of the views of the BVI business company's directors on commercial matters;


(c) whether the proceedings are likely to succeed;

(d) the costs of the proceedings in relation to the relief likely to be obtained; and

(e) whether an alternative remedy to the derivative claim is available.

Requisition of Meetings

The BCBCA provides that one or more shareholders of a company may requisition a general meeting for the purposes of transacting any business that may be transacted at a general meeting provided that such shareholder or shareholders hold in the aggregate, at the date on which the requisition is received by the company, at least 1/20 of the issued voting shares of the company. On receiving a compliant requisition, the directors must call a general meeting to be held within 4 months after the date on which the requisition is received. If the directors do not, within 21 days after the date on which the requisition is received by the company, send notice of a general meeting in accordance with the BCBCA, the requisitioning shareholders, or any one or more of them holding, in the aggregate, more than 1/40 of the issued shares of the company that carry the right to vote at general meetings, may send notice of a general meeting to be held to transact the business stated in the requisition.

Under the BVIBCA, subject to the memorandum and articles of association, the directors of a company shall call a meeting of the members if requested to do so by members entitled to exercise at least 30% of the voting rights in respect of the matter for which the meeting is requested. If the directors do not within 21 days after receiving such request call a meeting, any shareholder who signed the request may call a meeting.

Aura's MAA provides that:

(a) Any director of Aura may convene meetings of the shareholders at such times and in such manner and places within or outside the British Virgin Islands as the director considers necessary or desirable, but the directors shall call a meeting of shareholders to inter alia elect or re-elect directors and ratify the appointment of the auditors of Aura, to be designated as an "Annual Meeting". A meeting of shareholders designated as an Annual Meeting shall be convened no later than fifteen months after the holding the last preceding Annual Meeting but no later than six months after the end of Aura's preceding financial year. The directors may also convene a meeting of shareholders which may be designated as a "Special Meeting" to consider matters other than the election or re-election of directors and ratify the appointment of auditors.

(b) Upon the written request of shareholders entitled to exercise 5% or more of the voting rights in respect of the matter for which the meeting is requested the directors shall convene a meeting of shareholders. If the directors do not within 21 days after receiving such request call a meeting, any shareholder who signed the request may call the meeting.

(c) While Aura has a class of securities listed on the Toronto Stock Exchange (the TSX), it shall hold and conduct Annual Meetings in accordance with the TSX Listing Rules. (Aura's MAA define "TSX Listing Rules" as the rules of the TSX as contained in the TSX Company Manual, or any other) rules of the TSX, which apply to the Company while the Company has a class of securities listed on the TSX, each as amended or replaced from time to time.

(d) The director convening a meeting shall give notice of the time and place of a meeting of shareholders not less than 21 days and not more than 60 days before the date of the meeting to: (a) those shareholders whose names appear as shareholders in Aura's register of members on the record date specified in the notice and are entitled to vote at the meeting; (b) the other directors; and (c) the auditor of the Company.

(e) The director convening a meeting of shareholders may fix as the record date for determining those shareholders that are entitled to vote at the meeting the date notice is given of the meeting, or such other date as may be specified in the notice, being a date more than 60 days nor less than 21 days prior to the date on which the meeting is to be held.

(f) If a record date is fixed, unless notice of the record date is waived in writing by every holder of a share of the class or series affected whose name is set out in the securities register at the close of business on the day the directors fix the record date, notice of the record date must be given at least 7 days before the record date by: (a) advertisement in a newspaper published or distributed in the place where Aura has its registered office and in each place in Canada where it has a transfer agent or where a transfer of its shares may be recorded; and (b) written notice to each stock exchange in Canada on which the shares of Aura are listed for trading.


(g) A meeting of shareholders held in contravention of the requirement to give notice is valid if shareholders holding at least all of the total voting rights on all the matters to be considered at the meeting have waived notice of the meeting and, for this purpose, the presence of a shareholder at the meeting shall constitute waiver in relation to all the shares which that shareholder holds.

Aura's MAA provides that while Aura has a class of securities listed on the TSX, it shall hold and conduct Annual Meetings in accordance with the TSX Listing Rules.

Place of Shareholders' Meetings

The BCBCA requires, except for a general meeting that is a partially electronic meeting or a fully electronic meeting, all general meetings of a company to be held in British Columbia unless: (i) a location outside the Province of British Columbia is provided for in the articles; (ii) the articles do not restrict the company from approving a location outside of the Province of British Columbia for holding of the general meeting and the location of the meeting is approved by the resolution required by the articles for that purpose or by ordinary resolution if no resolution is required for that purpose by the articles; or (iii) the location for the meeting is approved in writing by the registrar before the meeting is held.

Subject to the memorandum and articles of association, the meetings of shareholders of a BVI business company may be held inside or outside of the BVI.

Aura's MAA provides that Aura may convene meetings of the shareholders at such times and in such manner and places within or outside the British Virgin Islands as the director considers necessary or desirable.

Directors' Residency Requirements

The BCBCA provides that a public company (such as Bluestone) must have at least three directors but does not establish any residency requirements for directors.

Subject to the requirements set out in the memorandum and articles of association, the BVIBC provides that a company must have at least one director but does not have any residency requirements for directors.

Aura's MAA impose no residency requirements. 

Aura's business activities do not require it to have a director or management presence in the BVI under the BVI's Economic Substance Act 2018 (as amended).

Removal of Directors

The BCBCA provides that a company may remove a director before the expiration of the director's term of office: (a) by a special resolution or, (b) by any other method of removal as specified in the articles. If shareholders holding a shares of a class or series of shares of a company have the exclusive right to elect or appoint one or more directors, a director so elected or appointed may only be removed by a separate special resolution of the shareholders of that class or series or by any other method as specified in the articles.

Subject to the memorandum and articles of association, the BVIBC provides that a director may be removed by resolution of the shareholders. Such shareholder resolution may only be passed at a meeting of members called for the purpose of removing the director or if by written resolution, passed by at least 75% of the votes of the shareholders entitled to vote. Where permitted under the memorandum or articles of association, a director of the company may also be removed by a resolution of the directors.


Aura's MAA provides that A director may be removed from office: (a) with or without cause, by resolution of shareholders passed at a meeting of shareholders called for the purpose of removing the director or for purposes including the removal of the director or by a written resolution passed by at least a majority of the votes of the shares of Aura entitled to vote; or (b) with cause, by resolution of directors passed at a meeting of directors called for the purpose of removing the director or for purposes including the removal of the director.

Issue of New Shares

The BCBCA permits shares with or without par value. Shares issued by a company governed by the BCBCA are non-assessable and may only be issued if consideration for such shares is fully paid.

Subject to the BVIBCA and the memorandum and articles of association, shares in the company may be issued, and options to acquire shares in a company granted, at such times, to such persons, for such consideration and on such terms as the directors may determine.

Under the BVIBCA, a statement of the maximum number of shares that the company is authorised to issue or that the company is authorised to issue an unlimited number of shares, and the classes of shares that the company is authorised to issue, and if the company is authorised to issue two or more classes of shares, the rights, privileges, restrictions and conditions attaching to each class of shares, must be included in the company's memorandum of association.

Under the BVIBCA, a share may be issued for consideration in any form, including money, a promissory note, or other written obligation to contribute money or property, real property, personal property (including goodwill and know-how), services rendered or a contract for future services. The consideration for a share with par value shall not be less than the par value of the share. If shares are to be issued by a company for a consideration other than money, then the directors are required to pass a resolution stating:

(a) the amount to be credited for the issue of the shares; and

(b) that, in their opinion, the present cash value of the non-money consideration for the issue is not less than the amount to be credited for the issue of the shares.

Aura's MAA provide that:

(a) Shares and other securities may be issued at such times, to such persons, for such consideration and on such terms as the directors may by resolution of directors determine.

(b) A share may be issued for consideration in any form or a combination of forms, including money, real property, personal property (including goodwill and know-how) or a contract for past services rendered.

(c) A share may not be issued for consideration in the form of a promissory note, or other written obligation to contribute money or property, or a contract for future services.

(d) Before issuing Shares for consideration which is, in whole or in part, other than money, a resolution of directors shall be passed stating:

(i) the amount to be credited for the issue of the shares; and

(ii) that, in the opinion of the directors, the present cash value of the non-money consideration and money consideration, if any, is not less than the amount to be credited for the issue of the shares.


Aura's MAA further provide that it is authorised to issue an unlimited number of shares of a single calls shares of no par value and that shares issued by Aura are non-assessable and the holders are not liable to Aura or its creditors in respect thereof.

Meaning of "insolvent"

Under the BCBCA, for purposes of the insolvency test that must be passed for the payment of dividends and purchases and redemption of shares, "insolvent" is defined to mean when a company is unable to pay its debts as they become due in the ordinary course of its business. The BCBCA does not impose a net asset solvency test for these purposes. For purposes of proceedings to dissolve or liquidate, the definition of "insolvent" from federal bankruptcy legislation applies.

Under the BVI's Insolvency Act, company or a foreign company is insolvent if:

(a) it fails to comply with the requirements of a statutory demand that has not been set aside under section 157 (Hearing to set aside statutory demand) of that Act;

(b) execution or other process issued on a judgment, decree or order of a BVI court in favour of a creditor of the company is returned wholly or partly unsatisfied; or

(c) either: (i) the value of the company's liabilities exceeds its assets; or (ii) the company is unable to pay its debts as they fall due.

Under the BVIBCA, a company must satisfy the 'solvency test' when making distributions to shareholders or acquiring shares from a shareholder. A company satisfies the solvency test if: (a) the value of the company's assets exceeds its liabilities; and (b) the company is able to pay its debts as they fall due. Where a director authorises a distribution by the company to its shareholders, the directors must be satisfied, on reasonable grounds, that immediately after the distribution, the company will satisfy the solvency test.

Reduction of Capital

Under the BCBCA, capital may be reduced by special resolution or court order. A court order is required if there are reasonable grounds for believing that the realizable value of the company's assets would, after the reduction of capital, be less than the aggregate of its liabilities.

There is no legal concept of capital for companies incorporated under the BVIBCA, therefore there is no requirement to follow a procedure or apply to court to reduce a company's capital. Where making a distribution, there's no requirement to pay a distribution from a specific source or out of available profits, the only requirement is that the company is able to satisfy the solvency test under the BVIBCA following distribution.

Aura's MAA authorises it to issue an unlimited number of Shares of a single class with no par value.

Shareholder Proposals

Under the BCBCA, a person submitting a proposal must have been the registered owner or beneficial owner of one of more voting shares for at least two years before signing the proposal. In addition, the proposal must be signed by shareholders who, together with the submitter, are registered or beneficial owners of (i) at least 1% of the company's voting shares, or (ii) shares with a fair market value exceeding an amount prescribed by regulation (at present, $2,000).

There is nothing under the BVIBCA that deals with shareholder proposals. However, Aura's MAA contain custom provisions that entitle submission of Shareholder proposals, as follows:

(a) Subject to eligibility and content requirements that follow, a shareholder entitled to vote at an Annual Meeting may:


(i) submit to Aura notice of any matter that such shareholder proposes to raise at the Annual Meeting (a "Proposal"); and

(ii) discuss at the Annual Meeting any matter in respect of which such shareholder would have been entitled to submit a proposal.

(b) To be eligible to submit a proposal, a person:

(i) must be, for at least the 6 month period immediately before the day on which the shareholder submits the proposal, a shareholder holding such number of shares: (A) that is equal to at least 1% of the total number of the outstanding shares of Aura, or (B) whose fair market value, as determined at the close of business on the day before the shareholder submits the proposal, is at least CDN$2,000; or

(ii) must have the support of persons who, in the aggregate, and including or not including the person that submits the proposal, have been, for at least the 6 month period immediately before the day on which the shareholder submits the Proposal, shareholders holding such number of shares: (A) that is equal to at least 1% of the total number of the outstanding shares of Aura, or(B) whose fair market value, as determined at the close of business on the day before the Shareholder submits the proposal, is at least CDN$2,000.

(c) A proposal must be accompanied by:

(i) the name and address of the shareholder and of the shareholder's supporters, if applicable; and

(ii) the number of shares held or owned by the shareholder and the shareholder's supporters, if applicable, and the date such shares were acquired.

Compulsory Acquisition

Under the BCBCA, each offer (an "Acquisition Offer") made by a person or 2 or more persons ("Acquiring Persons") to acquire shares, or any class of shares, of a British Columbia company is accepted if, within 4 months after the making of the Acquisition Offer, the Acquisition Offer is accepted regarding the shares, or regarding each class of shares involved, by shareholders who, in the aggregate, hold at least 9/10 of those shares or of the shares of that class of shares, other than shares already held at the date of the offer by, or by a nominee for, the acquiring person or its affiliate. If an Acquisition Offer is accepted as set out above, the Acquiring Person may, within 5 months after making the offer, send written notice to any offeree (a "Non-accepting Offeree") who did not accept the Acquisition Offer (the "Notice"), that the Acquiring Person wants to acquire the shares of that Non-accepting Offeree that were involved in the offer; if such Notice is sent to a Non-accepting Offeree, the Acquiring Person is entitled and bound to acquire all of the shares of that Non-accepting Offeree that were involved in the offer for the same price and on the same terms contained in the Acquisition Offer unless the Court orders otherwise on an application made by that Non-accepting Offeree within 2 months after the date of the Notice. If an Acquiring Person has not, within one month after being entitled to do so, sent the Notice, the Acquiring Person must send a written notice to each Non-accepting Offeree stating that the Non-accepting Offeree, within 3 months after receiving the Notice¸may require the Acquiring Person to acquire the shares of that Non-accepting Offeree that were involved in the Acquisition Offer. If a Non-accepting Offeree requires the Acquiring Person to acquire the Non-accepting Offeree's shares, the Acquiring Person must acquire those shares for the same price and on the same terms contained in the Acquisition Offer.

Under the BVIBC, subject to the memorandum or articles of association of a company, shareholders of the company holding 90 per cent. of the votes of the outstanding shares entitled to vote may give a written instruction to a company directing the company to redeem the shares held by the remaining members. Upon receipt of the written instruction, the company is required to redeem the shares specified in the written instruction irrespective of whether or not the share are by their terms redeemable and give written notice to each member whose shares are to be redeemed stating the redemption price and the manner in which the redemption is to be effected.


Investigation / Appointment of Inspectors

Under the BCBCA, a company may, by special resolution, appoint an inspector to investigate the affairs and management of the company, and to report in the manner and to the persons the resolution directs. One or more shareholders who, in the aggregate, hold at least 20% of the issued shares of a company may apply to the Court for the appointment of an inspector. The Court may make an order to appoint an inspector if it appears to the Court that there are reasonable grounds for believing that: (a) the affairs of the company are being or have been conducted, or the powers of the directors are being or have been exercised, in a manner that is oppressive or unfairly prejudicial to one or more shareholders, including the applicant; (b) the business of the company is being or has been carried on with intent to defraud any person; (c) the company was formed for a fraudulent or unlawful purpose or it is to be dissolved for a fraudulent or unlawful purpose; or (d) persons concerned with the formation, business or affairs of the company have, in connection with it, acted fraudulently or dishonestly.

Under the BVIBCA a shareholder or the Registrar may apply to the BVI court ex parte or upon such notice as the BVI court may require, for an order directing that an investigation be made of the company and any of its affiliated companies.

If, upon an application it appears to the BVI court that:

(a) the business of the company or any of its affiliates is or has been carried on with intent to defraud any person;

(b) the company or any of its affiliates was formed for a fraudulent or unlawful purpose or is to be dissolved for a fraudulent or unlawful purpose; or

(c) persons concerned with the incorporation, business or affairs of the company or any of its affiliates have in connection therewith acted fraudulently or dishonestly;

the BVI court may make any order it thinks fit with respect to an investigation of the company and any of its affiliated companies by an inspector, who may be the Registrar.

(TORONTO TIME) ON THE ELECTION DEADLINE (AS DEFINED BELOW), YOU WILL BE DEEMED TO HAVE ELECTED TO RECEIVE THE CASH CONSIDERATION (AS DEFINED BELOW).

LETTER OF TRANSMITTAL AND ELECTION FORM

FOR COMMON SHARES OF BLUESTONE METALS INC.

This Letter of Transmittal, or an originally signed facsimile, is for use by registered holders ("Bluestone Shareholders", and together with registered holders of Bluestone options, "Bluestone Securityholders") of common shares ("Bluestone Shares") of Bluestone Resources Inc. ("Bluestone") in connection with the proposed plan of arrangement (the "Arrangement") involving the acquisition of all of the outstanding Bluestone Shares by Aura Minerals Inc. ("Aura") pursuant to an arrangement agreement among Bluestone and Aura dated October 25, 2024, as amended, that is being submitted for approval at the meeting of Bluestone Securityholders to be held on December 19, 2024 (the "Bluestone Meeting"). Bluestone Shareholders are referred to the Notice of Special Meeting and management information circular dated November 12, 2024 (the "Circular") prepared in connection with the Bluestone Meeting that accompanies this Letter of Transmittal. The terms and conditions of the Plan of Arrangement, which is attached as Appendix "B" to the Circular, are incorporated by reference in this Letter of Transmittal. Capitalized terms used but not defined in this Letter of Transmittal have the meanings set out in the Circular. You are encouraged to read the Circular in its entirety.

The Plan of Arrangement contemplates that Bluestone Shareholders (other than Dissenting Shareholders) will be entitled to receive, in consideration for each Bluestone Share held, consideration (the "Consideration") consisting of,

(a) one contingent value right of Aura ("CVR") entitling a Bluestone Shareholder to receive, subject to the satisfaction of the CVR Payment Conditions prior to the CVR Termination Date, up to $0.2120; and (b) at the Bluestone Shareholder's election, either:

(i) C$0.2870 in cash (the "Cash Consideration"); or

(ii) 0.0183 of an Aura Share (the "Share Consideration") subject to proration.

Furthermore, each Bluestone Shareholder may indicate (i) the number of Bluestone Shares for which such shareholder elects to receive the Cash Consideration and (ii) the number of Bluestone Shares for which such shareholder elects to receive the Share Consideration, subject to proration.

In the event that the aggregate amount of Share Consideration that would otherwise be payable but for proration exceeds the Aggregate Share Consideration, then: (i) the portion of the consideration in respect of each Bluestone Share transferred to Aura to be satisfied by the issuance of Aura Shares shall be determined by multiplying the Share Consideration by the Share Proration Factor; and (ii) the balance of the consideration in respect of each Bluestone Share transferred to Aura to be satisfied by the payment of cash which is determined by multiplying the Cash Consideration by an adjustment factor equal to one minus the Share Proration Factor.


In the case where no Consideration election is made prior to the Election Deadline (as defined below), a Bluestone Shareholder will be deemed to have elected to receive the Cash Consideration. The Share Consideration is subject to proration under which a Bluestone Shareholder may receive both cash and Aura Shares in exchange for Bluestone Shares regardless of the Bluestone Shareholder's election to receive the Share Consideration.

The election available to you in respect of the Consideration you may receive under the Arrangement is an investment decision which carries tax consequences. You should consult your own investment and tax advisors prior to making your election. If you elect to receive the Share Consideration, your election may be prorated in which case you will receive some amount of the Cash Consideration.

No fractional Aura Shares will be issued pursuant to the Arrangement. Where the aggregate number of Aura Shares to be issued to a Bluestone Shareholder would result in a fraction of an Aura Share being issuable, the number of Aura Shares will be rounded down to the nearest whole Aura Share, and the fractional entitlement will be cancelled without any compensation or other consideration. If the aggregate cash amount a Bluestone Shareholder is entitled to receive would otherwise include a fraction of $0.01, then the aggregate cash amount such Bluestone Shareholder shall be entitled to receive shall be rounded up to the nearest whole $0.01.

In order to receive the appropriate number of whole Aura Shares and/or cash that a Bluestone Shareholder is entitled to receive under the Arrangement, Bluestone Shareholders are required to deposit:

1. the certificate(s) or DRS Advice representing Bluestone Shares held by them, if any, with the Depositary;

2. this Letter of Transmittal, properly completed and duly executed; and

3. all other required documents.

For your election to be effective, this Letter of Transmittal, properly completed and duly executed, and accompanied by the certificate(s) or DRS Advice representing your Bluestone Shares, if any, together with all other documents required by the Depositary, must be received by the Depositary no later than 4:30 p.m. (Toronto time) on December 16, 2024, or, if the Meeting is adjourned or postponed, no later than 72 hours (excluding Saturdays, Sundays and statutory holidays in British Columbia) before the adjourned Meeting is reconvened or the postponed Meeting is convened (the "Election Deadline") at the address specified on the back page of this Letter of Transmittal. If the Depositary does not receive the required documentation or you otherwise fail to make a proper election by the Election Deadline (or any extension thereof), you will be treated as a non-electing Bluestone Shareholder as described above and you will be deemed to have elected to receive the Cash Consideration in respect of each Bluestone Share held. Bluestone Shareholders who do not deliver their Bluestone Share certificate(s) or DRS Advice, if any, and all other required documents to the Depositary on or before the date which is six years after the Effective Date shall lose their right to receive the Consideration for their Bluestone Shares.

Pursuant to the Arrangement, you will cease to be a Bluestone Shareholder as of the Effective Date and will only be entitled to receive the Rights Certificate representing CVRs, share certificate(s) or DRS Advice, as applicable, representing Aura Shares and/or cash to which you are entitled under the Arrangement.

The Arrangement is subject to a number of conditions, some of which are beyond the control of Bluestone and Aura. Accordingly, the exact timing of the implementation of the Arrangement is not currently known. Aura and Bluestone currently expect the Arrangement to become effective in January 2025.

This Letter of Transmittal is for use by registered Bluestone Shareholders only.

elected
 
Total  

Notes:

1. In the event the aggregate amount of Share Consideration that would otherwise be issuable to Bluestone Shareholders electing the Share Election pursuant to the Plan of Arrangement exceeds the Aggregate Share Consideration, then the Consideration payable for each Bluestone Share for which a Share Election has been made shall consist of: (i) one CVR; (ii) a number of Aura Shares equal to the Share Consideration multiplied by the Share Proration Factor; and (iii) a cash payment equal to the Cash Consideration multiplied by an adjustment factor equal to one minus the Share Proration Factor.

2. Where the aggregate number of Aura Shares to be issued to a Bluestone Shareholder would result in a fraction of an Aura Share being issuable, the number of Aura Shares will be rounded down to the nearest whole Aura Share, and the fractional entitlement will be cancelled without any compensation or other consideration. If the aggregate cash amount a Bluestone Shareholder is entitled to receive would otherwise include a fraction of $0.01, then the aggregate cash amount such Bluestone Shareholder shall be entitled to receive shall be rounded up to the nearest whole $0.01. Bluestone Shareholders should refer to the full text of the Plan of Arrangement which is attached as Appendix B to the Circular.

3. The total number of Bluestone Shares for which you make a Cash Consideration election above plus the total number of Bluestone Shares for which you make a Share Consideration election above (collectively your "Total Elected Shares") must equal your Deposited Shares. If your Total Elected Shares is less than your Deposited Shares, you will be deemed to have elected to receive the Cash Consideration for the Bluestone Shares for which an election is not made. If your Total Elected Shares is more than your Deposited Shares, the number of Bluestone Shares for which you have elected to receive Cash Consideration will be reduced accordingly.

4. If you do not make an election as to the applicable Consideration you wish to receive under the Arrangement, you will be deemed to have elected to receive the Cash Consideration for all Bluestone Shares held.

5. You should consult your own investment and tax advisors prior to making an election as to the Consideration you wish to receive under the Arrangement.

It is understood that, upon receipt of this Letter of Transmittal properly completed and duly executed together with the certificate(s) and DRS Advice, if any, representing the Deposited Shares and following the Effective Time of the Arrangement, the Depositary will cause the delivery to the undersigned of the Consideration that the undersigned elected to receive and is entitled to receive under the Arrangement, or hold such Consideration for pick-up in accordance with the instructions set out below, and any certificate(s) or DRS Advice representing the Deposited Shares shall forthwith be cancelled. It is understood that all payments (including delivery of Aura Shares) will be net of any amounts required to be withheld by law including in respect of applicable taxes, payroll deductions or similar amounts. Pursuant to and as required by applicable laws, Aura, Bluestone and the Depositary, as applicable, shall withhold any amounts whatsoever from the amounts otherwise payable or otherwise deliverable to a Bluestone Shareholder and remit such amounts to the applicable government authorities.

The undersigned registered holder(s) of the above-listed Deposited Shares hereby:

1. Represents and warrants in favour of Bluestone and Aura that: (i) the undersigned is, and will immediately prior to the Effective Time be, the registered holder of the Deposited Shares; (ii) such Deposited Shares are owned by the undersigned free and clear of all mortgages, liens, charges, encumbrances, security interests and adverse claims; (iii) the undersigned has full power and authority to execute and deliver this Letter of Transmittal and to deposit, sell, assign, transfer and deliver the Deposited Shares and that, when the Consideration is paid, none of Bluestone and Aura, or any successor thereto, will be subject to any adverse claim in respect of such Deposited Shares; (iv) the Deposited Shares have not been sold, assigned or transferred, nor has any agreement been entered into to sell, assign or transfer any such Deposited Shares, to any other person; (v) the surrender of the Deposited Shares complies with applicable Laws; (vi) all information inserted by the undersigned into this Letter of Transmittal is accurate; (vii) unless the undersigned has revoked this Letter of Transmittal by notice in writing given to the Depositary prior to the Effective Date, the undersigned will not, prior to such time, transfer or permit to be transferred any of such Deposited Shares; and (viii) the delivery of the appropriate number of CVRs, Aura Shares and appropriate Cash Consideration to the undersigned will completely discharge any and all obligations of Bluestone, Aura and the Depositary with respect to the matters contemplated by this Letter of Transmittal. These representations and warranties shall survive the completion of the Arrangement.

8. U.S. Shareholders and Backup Withholding

To prevent United States federal backup withholding tax from applying to a payment of the Cash Consideration and any payments in respect of the CVRs, each to the extent applicable, made to a U.S. Shareholder (or any person acting on behalf of a U.S. Shareholder) pursuant to the Arrangement, each U.S. person (as defined below) must provide his, her or its correct U.S. Taxpayer Identification Number, or TIN (or the TIN of the person on whose behalf you are acting), and certain other information, by completing the enclosed IRS Form W-9. If a completed IRS Form W-9 is not provided, or if the correct TIN is not provided on such form, or if any other information is not correctly provided, payments of the Cash Consideration and any payments in respect of the CVRs, each to the extent applicable, made with respect to the Bluestone Shares may be subject to backup withholding by the Depositary at the rate of 24%.

For the purposes of this Letter of Transmittal, "U.S. person" means: a beneficial owner of Bluestone Shares that, for United States federal income tax purposes, is (a) a citizen or resident of the United States, (b) a corporation, or other entity classified as a corporation for United States federal income tax purposes, that is created or organized in or under the laws of the United States or any state in the United States, including the District of Columbia or otherwise classified as a domestic corporation for U.S. federal income tax purposes, (c) an estate if the income of such estate is subject to United States federal income tax regardless of the source of such income, (d) a trust if (i) such trust has validly elected to be treated as a U.S. person for United States federal income tax purposes or (ii) a United States court is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of such trust, or (e) a partnership, limited liability company or other entity classified as a partnership for United States tax purposes that is created or organized in or under the laws of the United States or any state in the United States, including the District of Columbia.

If the enclosed IRS Form W-9 does not apply to a U.S. Shareholder because such holder is not a U.S. person for United States federal income tax purposes but provided a mailing address in the United States, such holder will instead need to submit a properly completed IRS Form W-8ECI, W-8IMY, W-8BEN or W-8BEN-E, as appropriate, signed under penalties of perjury. An appropriate IRS Form W-8 may be obtained from the Depositary or from the IRS website (www.irs.gov).

Backup withholding is not an additional United States income tax. Rather, the United States income tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If backup withholding results in an overpayment of taxes, a refund may be obtained provided that the required information is timely furnished to the IRS.

Certain persons (including, among others, corporations, certain "not-for-profit" organizations, and certain non-U.S. persons) are not subject to backup withholding.

The TIN for an individual United States citizen or resident is the individual's social security number or individual taxpayer identification number.

If a Bluestone Shareholder that is a U.S. person has not been issued a TIN and has applied for a TIN or intends to apply for a TIN in the near future, then such Bluestone Shareholder should write "Applied For" in Part I of the IRS Form W-9. A Bluestone Shareholder that is a U.S. person waiting for a TIN to be issued or has not specified a TIN in the completed IRS Form W-9 must provide a TIN within 60 days, otherwise payments of the Cash Consideration and any payments in respect of the CVRs, each to the extent applicable, made with respect to the Bluestone Shares may be subject to backup withholding of 24% by the Depositary.


Failure to furnish TIN - If you fail to furnish your correct TIN, you may be subject to a penalty of U.S.$50 for each such failure unless your failure is due to reasonable cause and not to willful neglect.

Each U.S. Shareholder is urged to consult his, her or its own U.S. tax advisor to determine whether such holder is required to furnish an IRS Form W-9, is exempt from backup withholding and information reporting, or is required to furnish an IRS Form W-8.
