GREYSTAR RESOURCES LTD. 
Notes to Interim Consolidated Financial Statements (unaudited) 
(Expressed in Canadian dollars) 
Three and six months ended June 30, 2010 
=------------------------------------------------------------------------------------ 
 
 1. Nature of operations 
 
    Greystar  Resources  Ltd. (the "Company") was formed effective August 15, 1997 by way  of  amalgamation 
    pursuant  to  the Company Act (British Columbia).  On May 5, 2005, the Company amended its articles  to 
    continue  under  the  Business Corporations Act (British Columbia).  The Company's  principal  business 
    activities include the acquisition, exploration and development of mineral properties. 
 
    These  unaudited  interim  consolidated financial statements have  been  prepared  in  accordance  with 
    Canadian   generally  accepted  accounting  principles  ("GAAP")  for  interim  financial   statements. 
    Accordingly,  they do not include all of the information and disclosures required by  GAAP  for  annual 
    consolidated  financial  statements. They have been prepared using the  same  accounting  policies  and 
    methods  of  application as the latest annual consolidated financial statements,  except  as  discussed 
    herein.  In  the  opinion of management, all adjustments (consisting of normal and recurring  accruals) 
    considered necessary for fair presentation have been included. The results for interim periods are  not 
    necessarily  indicative  of  results for the entire year. The information contained  in  the  unaudited 
    interim  consolidated  financial statements should be read in conjunction  with  the  Company's  latest 
    annual  consolidated financial statements for the year ended December 31, 2009, and the notes  thereto. 
    All  significant inter-company transactions and balances have been eliminated. Certain amounts in prior 
    periods have been reclassified to conform to the 2010 presentation. 
 
    The  preparation  of these interim consolidated financial statements in conformity with  GAAP  requires 
    management  to  make  estimates  and  assumptions that  affect  the  reported  amounts  of  assets  and 
    liabilities  and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  interim 
    consolidated financial statements and the reported amounts of expenses during the period. As a  result, 
    actual amounts may differ from those estimates. 
 
    The  Company  is in the process of exploring its mineral properties and has not yet determined  whether 
    they  contain  resources that are economically recoverable.  Management anticipates  that  the  Company 
    will  continue  to  raise  adequate funding through equity or debt financings,  although  there  is  no 
    assurance  that  the  Company  will  be  able  to obtain adequate  funding  on  favorable  terms.   The 
    recoverability  of amounts shown for mineral properties and equipment is dependent upon  the  discovery 
    of  economically recoverable reserves, the ability of the Company to obtain the necessary financing  to 
    complete  exploration and development, confirmation of the Company's interest in the underlying  claims 
    and  leases,  the ability of the Company to obtain the necessary mining permits, and future  profitable 
    production or proceeds from the disposition of the mineral properties. 
 
    At  June  30, 2010, the Company had working capital of $112,006,645 but had not yet achieved profitable 
    operations and expects to incur further losses in the development of its business.  For the six  months 
    ended  June  30, 2010, the Company reported a net loss of $14,813,650 and as at June 30, 2010,  had  an 
    accumulated  deficit of $152,036,139.  The ability of the Company to continue as  a  going  concern  is 
    dependent  upon  the Company's ability to arrange additional funds to complete the development  of  its 
    property and upon future profitable operations. 
 
    In  December  2009,  the Company filed its Environmental Impact Assessment ("EIA") with  the  Colombian 
    Ministry  of  Environment, Housing and Territorial Development ("MAVDT") in respect to the  development 
    of  an  open pit gold-silver mine at the Company's Angostura project in Colombia.  On April  20,  2010, 
    the  MAVDT  requested  a  new  EIA to be filed that conforms to a new regulation  which  calls  for  an 
    adjustment  of  the occupied area outside of 'paramo', which was interpreted as at an  elevation  above 
    3,200  metres.  MAVDT's  request would have required the Angostura project to be completely  redesigned 
    and  would  have  severely  impacted the project schedule and may have had a  material  effect  on  its 
    economic viability. 
 
    On  April  29, 2010, the Company filed an appeal of the notification from MAVDT.  On May 28, 2010,  the 
    Company  received  a  letter from MAVDT that reinstated the Company's EIA as filed.   MAVDT  will  move 
    forward  with  a  review of the Company's EIA as originally filed. On July 15,  2010,  MAVDT  issued  a 
    notice  to  the  Company  that,  at  the  request of third  parties,  information  meetings  for  local 
    communities  that  were  being  planned by the Company are to be incorporated  into  a  public  hearing 
    process.  The  public  hearing will hear the views and opinions of certain interested  parties  on  the 
    environmental  impact  of  the  Angostura project.  The dates of the information  meetings  and  public 
    hearing  are  being established with MAVDT and are steps in the process relating to the  decision  from 
    MAVDT on issuing an environmental permit for the Angostura project. 
 
 2.      New accounting pronouncements 
 
        (i) Business Combinations 
 
            In  October  2008,  the CICA issued CICA Handbook Section 1582, "Business Combinations",  which 
            establishes  new  standards for the recognition, measurement, presentation  and  disclosure  of 
            business  acquisitions.  This  standard is substantially aligned with  International  Financial 
            Reporting  Standards.  This is effective for business combinations for  which  the  acquisition 
            date  is  on or after the beginning of the first annual reporting period beginning on or  after 
            January  1,  2011.   Should  the  Company engage in a future  business  combination,  it  would 
            consider  early  adoption  to coincide with the adoption of International  Financial  Reporting 
            Standards.  The  Company is currently assessing the impact of this accounting standard  on  the 
            Company's financial position and results from operations. 
 
        (ii)Non-controlling Interests 
 
            In  October  2008,  the  CICA  issued  CICA  Handbook Sections  1601,  "Consolidated  Financial 
            Statements"  and  1602,  "Non-controlling Interests", which provide  revised  guidance  on  the 
            presentation of consolidated financial statements and accounting for non-controlling  interests 
            subsequent to a business combination. This guidance is effective for fiscal years beginning  on 
            or  after  January  2011.  The Company is currently assessing the  impact  of  this  accounting 
            standard on the Company's financial position and results from operations. 
 
         (iii)      International Financial Reporting Standards ("IFRS") 
 
            In  February  2008,  the AcSB confirmed that 2011 is the changeover date for  publicly-  listed 
            companies  to  use IFRS.  The date is for interim and annual financial statements  relating  to 
            fiscal  years beginning on or after January 1, 2011.  The transition date of January  1,  2011, 
            will require our 2010 comparatives to be presented according to IFRS. 
 
            Key dates: 
 
            - January 1, 2010 (transition date): An opening statement of financial position according to IFRS 
              will be prepared as at this date to facilitate the changeover to IFRS in 2011. The Company will 
              continue to report its fiscal 2010 and comparative 2009 results according to Canadian GAAP. 
            - January 1, 2011 (changeover date): The date after which the Company will prepare and report 
              interim and annual 2011 financial statements with 2010 comparatives according to IFRS. 
 
            While  the  Company continues to perform detailed assessments of the impact of  adopting  IFRS, 
            the full impact of the transition to IFRS cannot be reasonably estimated at this time. 
 
 3. Restricted cash 
 
    Pursuant  to  the  land acquisition agreement, the Company was required to make a progress  payment  of 
    $637,100  in April 2010 for the Las Puentes land parcel it acquired in June 2009. However,  certain  of 
    the  original Las Puentes vendors are currently in a title dispute with another unrelated  group.   The 
    Company  believes  that its title to the Las Puentes land parcel is not at risk,  but  has  placed  the 
    $637,100  progress payment into an escrow account pending settlement of the title dispute  amongst  the 
    vendors  and  the unrelated group. The Company expects this dispute to be settled within  the  next  12 
    months.

Results of Operations 
 
The  net  loss for the three months ended June 30, 2010, was $8.9 million compared to $6.0 million for  the 
comparative period in 2009. Loss per share for the three months ended June 30, 2010, was $0.11 compared  to 
$0.11 for the comparative period in 2009. 
 
The  net  loss for the six months ended June 30, 2010, was $14.8 million compared to $9.7 million  for  the 
comparative  period in 2009. Loss per share for the six months ended June 30, 2010, was $0.18  compared  to 
$0.19 for the comparative period in 2009. 
 
On  April  20,  2010, the Colombian Ministry of Environment, Housing and Territorial Development  ("MAVDT") 
requested a new Environmental Impact Assessment ("EIA") to be filed that conforms to a new regulation which 
calls  for an adjustment of the occupied area outside of 'paramo', which was interpreted as at an elevation 
above 3,200 metres. On April 29, 2010, Greystar filed an appeal on the rejection of its EIA from MAVDT.  On 
May  28,  2010 the Company received a letter from MAVDT that reversed its April 20th letter and  reinstates 
the  December  22,  2009  EIA as filed.  MAVDT will move forward with a review  of  the  Company's  EIA  as 
originally  filed.  On July 15, 2010, MAVDT issued a notice to the Company that, at the  request  of  third 
parties,  information  meetings for local communities that were being planned by  the  Company  are  to  be 
incorporated into a public hearing process. The public hearing will hear the views and opinions of  certain 
interested  parties  on the environmental impact of the Angostura project.  The dates  of  the  information 
meetings and public hearing are being established with MAVDT and are steps in the process relating  to  the 
decision from MAVDT on issuing an environmental permit for the Angostura project. 
 
Management Changes 
 
Mr.  Steve  Kesler assumed the President and Chief Executive Officer role following the retirement  of  Mr. 
David Rovig who has assumed the position of Non-Executive Chairman of the Board.  In July 2010, the Company 
announced  the  appointment of David Newbold as Chief Financial Officer, effective August 3,  2010.   Geoff 
Chater stepped down from the position of Vice President Corporate Development effective June 30, 2010. 
 
2.      ANGOSTURA GOLD-SILVER PROJECT UPDATE, COLOMBIA 
 
On March 25, 2009, the Company announced that GRD Minproc Ingeniería y Construcción Ltda. Chile ("Minproc") 
completed  a  prefeasibility study ("PFS") for the Angostura project. The PFS  was  prepared  based  on  an 
updated NI 43-101 resource estimate completed by Greystar staff under the overall supervision of consulting 
company  Metálica  Consultores S.A. from Chile. The updated NI 43-101 resource estimate  is  available  for 
review on SEDAR at www.sedar.com. 
 
On  June  1, 2009, the Company announced that Minproc will prepare a feasibility study ("FS"). The FS  will 
provide technical evaluations, engineering designs, capital and operating costs for the mine, mill, process 
plant  and site infrastructure, as well as the financial analysis of the project. The FS will also  include 
the basic engineering of the project and continue to refine work completed during the prefeasibility phase. 
 
Feasibility Study 
 
The  FS includes three well-defined stages: Optimization, Design and Economics, each looking to improve the 
technical and financial parameters defined in the PFS stage, but also to reduce risk on all fronts. The  FS 
will  include basic engineering in all disciplines and is expected to have a level of accuracy of +/-  15%. 
The  FS  report  will provide the basis for project financing. During the first half of 2010, approximately 
$3.1 million was spent on the various components of the FS, including assay and metallurgical analysis. 
 
Resource Update 
 
On  July  15,  2010,  Greystar  announced an updated resource calculation for the  Angostura  project.  The 
resource study is based on updated 3D geological and mineral models, and includes all of the technical data 
available  as  of  January  2010, including 179,813 core assays from 938 drill holes  representing  302,834 
metres,  and 1,768 muck samples from the exploration tunnels.  The resource study was developed by Greystar 
under  the  overall  supervision  of consulting company NCL Ingeniería y  Construcción  S.A.  ("NCL")  from 
Santiago, Chile. 
 
Additional  drilling  carried  out  in  2008 and the rigorous evaluation  of  the  resource  by  Greystar's 
geological  staff working closely with NCL has provided a robust resource model for the FS.   Greystar  has 
initiated  the  evaluation  of  underground resources that lie beyond the FS  pit  boundary  but  within  a 
proximity to allow exploitation utilizing the pit infrastructure either during or after completing the open 
pit  operation. As the cut-off date for the data employed in this resource study was January 2010, not  all 
of  the  recent  Los  Laches drilling data has been included.  The evaluation of underground  potential  at 
Angostura  is  a work in progress; however, early indications are that underground resources could  have  a 
meaningful impact on the project. 
 
Resource Highlights: 
 
This  resource  statement  was  made using a gold price of US$850/oz and a silver  price  of  US$12/oz.  In 
developing  this  resource for the FS, a more conservative view was taken on higher grade  material,  which 
included  grade  capping and reduced search area to make the resource more robust  in  support  of  project 
financing. Details of the operational pit and underground resources are provided in the tables below:

On  July  15,  2010, Greystar announced an updated metallurgical recovery model ("FS Recovery  Model")  and 
process  flow  for  the  Angostura project.  The updated model, which will  be  incorporated  into  the  FS 
scheduled for publication in the second half of 2010, replaces the metallurgical model used in the May 2009 
Preliminary Feasibility Study ("PFS Recovery Model"). 
 
The results of the metallurgical testing have the following average gold recoveries by ore type.

    5.      High  grade  ore circuit average metallurgical results in the FS Recovery Model based  on  91% 
            flotation gold recovery, 90% BIOX® /CIP recovery, and 50% heap leaching recovery of flotation tails 
            agglomerates. 
    6.      Heap leach feed size sensitivity (38mm vs. 19mm) employed for the FS Recovery Model was determined 
            considering only samples tested at both feed sizes, rather than average results as presented in the table 
            shown above. 
 
Updates to the recovery model include: 
 
-  A coarsening of the planned heap leach feed size to 38mm. 
-  A new geo-metallurgical model to project heap leach recoveries. 
-  A  revision  to the high grade recovery circuit to include stirred tank bio-oxidation and carbon-in-pulp 
   cyanidation of the flotation concentrate. 
 
The FS metallurgical processing routes for the Angostura ore will be driven by the FS Recovery Model with: 
 
-  Oxide,  transitional  and  low-grade  sulphide ore processed by  conventional  cyanide  heap  leach  and 
   agglomerated flotation tailings heap leach. 
 
-  High  grade  sulphide mineralization treated via milling, flotation, stirred tank bio-oxidation,  carbon 
   in  pulp cyanidation of bio-oxidized residue and pulp agglomeration heap leaching of flotation tailings. 
   The  flotation  plant size will be increased above the 5,200 tonnes per day identified  in  the  PFS  to 
   treat the higher quantity of sulphides that are now economic through use of BIOX(R). 
 
Stirred-tank  bio-oxidation of the Angostura flotation concentrate followed by cyanidation of the  oxidized 
residue  was  found  to  be more solid and economically attractive than direct shipment  of  the  flotation 
concentrate  to  a  smelter  (PFS  Recovery Model), roasting of the  flotation  concentrate  with  agitated 
cyanidation  of  the roasted calcine, or pressure oxidation ("POX") treatment with agitated cyanidation  of 
the  POX  residue. The comparative process routes were analyzed in GRD Minproc/AMEC/NCL/Greystar  trade-off 
studies.  Ultra-fine grinding and leaching of flotation concentrate was also evaluated during metallurgical 
testing  at  G&T Metallurgical, but the resulting gold and silver recoveries were too low for consideration 
in  the  trade-off  study.   A  preliminary  stirred-tank test at McClelland  Laboratories,  confirmed  the 
amenability  of  the  Angostura  flotation  concentrate to bio-oxidation  with  subsequent  carbon-in-leach 
cyanidation of the bio-oxidation residue. Based on these positive results, Greystar contracted Gold  Fields 
Limited,  the  world leader in tank bio-oxidation processing, for a continuous BIOX(R) mini-pilot  plant  run 
using  bulk flotation concentrate from the Angostura deposit. Flotation concentrate preparation and testing 
associated with the BIOX® pilot plant is being done at SGS Lakefield Research Africa in Johannesburg  under 
the  direction of Gold Fields Technical Division, BIOX® Department. This test program, to be  completed  by 
October  2010, will provide the necessary data for designing the commercial bio-oxidation treatment  plant, 
establishing  optimum conditions for gold recovery, recycling of toxin-free solution from the  BIOX®  plant 
and generating an environmentally stable solid waste product. 
 
The  results  of the bio-oxidation test programs will be incorporated in the FS. The Company will  continue 
with  the  design  of  the heap leach facilities for treating oxide and transitional  ore,  and  low  grade 
sulphides,  as well as the design of the grinding and flotation circuit for the higher-grade sulphide  ore. 
Furthermore,  the  Company will continue to move forward with all other aspects of the  project,  including 
geotechnical  evaluations,  social and environmental studies, permitting, infrastructure  construction  and 
project finance.

October 23, 2009          The  Company submitted an application for a Work and Investment Plan (PTO)  based 
                          on  the  PFS. The PTO was submitted to the Ingeominas, a division in the Ministry 
                          of  Mines  and  Energy, on October 23, 2009.  The PTO is the operating  plan  for 
                          Angostura  which  must  be approved by Ingeominas in a parallel  process  to  the 
                          environmental  permitting.   Both the EIA and the PTO must be  approved  for  the 
                          issuance of a mining license. 
=---------------------------------------------------------------------------------------------------------- 
December 22, 2009         The  Company  filed  the EIA with MAVDT to initiate the environmental  permitting 
                          process  for the development of an open pit gold and silver mine at the Angostura 
                          project   in  Colombia.  The  EIA,  which  is  based  on  the  PFS,  covers   all 
                          environmental  and  social  aspects of the proposed  mine  development  including 
                          baseline data and end of mine life mitigation plans. 
=---------------------------------------------------------------------------------------------------------- 
April 20, 2010            MAVDT  requested a new EIA to be filed. MAVDT requested that the new EIA  conform 
                          to  new  regulation Law 1382 of 2010 (Modified Mining Code) which  requires  that 
                          mining and exploration activity must be excluded from the "Paramo" ecosystem. 
=---------------------------------------------------------------------------------------------------------- 
April 29, 2010            The Company filed an appeal of the April 20th notification from MAVDT 
=---------------------------------------------------------------------------------------------------------- 
May 28, 2010              The  Company received a letter from MAVDT that reversed its April 20th letter and 
                          reinstates  the December 22, 2009 EIA as filed.  MAVDT will move forward  with  a 
                          review of the EIA. 
=---------------------------------------------------------------------------------------------------------- 
July 15, 2010             MAVDT  issued  a  notice to the Company that, at the request  of  third  parties, 
                          information  meetings  for  local communities that  were  being  planned  by  the 
                          Company  are to be incorporated into a public hearing process. The public hearing 
                          will  hear  the  views  and  opinions  of  certain  interested  parties  on   the 
                          environmental  impact  of the Angostura project.  The dates  of  the  information 
                          meetings  and  public hearing are being established with MAVDT and are  steps  in 
                          the  process  relating  to  the decision from MAVDT on issuing  an  environmental 
                          permit for the Angostura project.

Exploration 
 
In  December  2009, the Company initiated an exploration drill program to investigate the La Plata  mineral 
property that was acquired in the La Baja Valley, located southwest of the Angostura deposit, and continued 
with  its  program  of  exploring the potential of high grade mineralization at the  Angostura  gold-silver 
deposit  and  near surface oxide gold and deeper sulphide mineralization discovered in 2008 at the  Mongora 
prospect. 
 
Los Laches Drill Program 
 
The  Company announced additional assay results from the targeted drill program at the Los Laches  area  of 
the  Angostura  gold-silver  deposit.  The new drill results from the Los Laches  Area,  whose  geology  is 
structurally  complex,  continue  to  provide  positive  results  showing  the  potential  of  high   grade 
mineralization at depth below the envisioned Preliminary Feasibility Study open pit. 
 
Mongora Drill Program 
 
Greystar  started 44 drill holes on the Mongora target, of which 21 have been completed  so  far  in  2010, 
bringing  the  total to 15,490 meters drilled as of July 29, 2010.  Similar to the Angostura  deposit,  the 
Mongora  prospect hosts higher-grade gold mineralization including  116 grams gold over 2.0  metres,   22.2 
grams  gold  per tonne over 2.0 metres and 12.35 grams over 1.6 metres within broader zones of  lower-grade 
gold mineralization. The delineation of significant oxide gold mineralization at the Mongora area could  be 
very important for the Angostura project. 
 
La Plata 
 
La  Plata  is  located  in the California mining district of Colombia. La Plata comprises  78  hectares  of 
mineral rights contiguous on the majority of its borders with existing Greystar holdings. 
 
The  La  Plata property lies within a mineralized belt related to the northeast-southwest trending La  Baja 
Fault,  which  has  given  rise  to  a number of mineralized occurrences. This  mineralization,  which  has 
traditionally  been  mined by local artisanal miners, is now the focus of more modern exploration  methods. 
Within the La Baja structural domain, gold and silver mineralization is associated with flexures along  the 
main fault. 
 
Exploration  carried  out by the Company during the second quarter of 2009 identified  vein  and  stockwork 
mineralization  associated  with  strong alteration hosted in a dacite porphyry.  Rock  samples  from  mine 
tunnels  on site returned gold assays ranging from no significant gold up to 9.66 grams per tonne gold  and 
silver  assays ranging from no significant silver up to 94.3 grams per tonne silver.  A drill  program  was 
initiated with one drill rig in February 2010.

Three months ended June 30, 2010 
 
Total exploration expenditures were $5.8 million for the three months ended June 30, 2010, compared to $4.3 
million  for  the  three  months  ended June 30, 2009.  Costs related to  feasibility  and  pre-feasibility 
(completed  in 2009) studies were $2.0 million for the three months ended June 30, 2010, compared  to  $1.5 
million for the comparative period in 2009. Exploration costs were greater for the three months ended  June 
30,  2010,  due  to the drill programs at Los Laches, Christo Rey, Mongora and La Plata properties.   These 
drilling  expenditures totalled $1.8 million in the three months ended June 30, 2010, compared to costs  of 
$0.6 million in the comparative period of 2009. 
 
General and administrative expenses increased by approximately $1.5 million for the three months ended June 
30, 2010, compared to the three months ended June 30, 2009.  The increase was a result of the following: 
 
    *   Management and consulting fees were up $0.5 million in 2010 compared to 2009, due primarily to the 
        engagement of consultants to recruit the CEO and CFO, tax reorganization consulting and compensation for 
        management services. 
    *   Salaries and benefits were up $0.4 million in 2010 compared to 2009, due primarily to the hiring 
        of additional corporate staff during the second half of 2009 and first half of 2010. 
    *   Stock-based  compensation increased by $0.5 million in 2010 compared to 2009,  due  to  higher 
        amortization resulting from the higher number and fair values for stock options granted during the first 
        half of 2010, and to higher amortization of the cost of prior period awards that vested during the period. 
 
Interest  income  for the three months ended June 30, 2010, increased by $0.3 million from the  comparative 
period in 2009, primarily due to the increased cash balances. 
 
The  Company had a small foreign exchange gain of $7,000 for the three months ended June 30, 2010, compared 
to a $0.2 million gain for the three months ended June 30, 2009. 
 
Six months ended June 30, 2010 
 
Total  exploration expenditures were $9.2 million for the six months ended June 30, 2010, compared to  $7.4 
million  for  the  six  months  ended  June 30, 2009.  Costs related  to  feasibility  and  pre-feasibility 
(completed  in  2009) studies were $3.1 million for the six months ended June 30, 2010,  compared  to  $2.9 
million  for the comparative period in 2009. Exploration costs were greater for the six months  ended  June 
30,  2010,  due  to the drill programs at Los Laches, Christo Rey, Mongora and La Plata properties.   These 
drilling expenditures totalled $2.9 million in the first half of 2010, compared to costs of $1.3 million in 
the comparative period of 2009. 
 
General  and administrative expenses have increased by approximately $3.5 million for the six months  ended 
June 30, 2010, compared to the six months ended June 30, 2009.  The following explains the increase in  the 
comparative quarters: 
 
    *   Management and consulting fees were up $0.9 million in 2010 compared to 2009, due primarily to the 
        engagement of consultants to recruit the CEO and CFO, tax reorganization consulting and compensation for 
        management services. 
    *   Salaries and benefits were up $0.9 million in 2010 compared to 2009, due primarily to the hiring 
        of additional corporate staff during the second half of 2009 and bonuses awarded to senior management 
        during the first quarter of 2010 as compared to no bonuses in the comparative quarter of 2009. 
    *   Stock-based  compensation increased by $1.4 million in 2010 compared to 2009,  due  to  higher 
        amortization resulting from the higher number and fair values for stock options granted during the first 
        half of 2010, and to higher amortization of the cost of prior period awards that vested during the period. 
 
Interest  income  for  the six months ended June 30, 2010, increased by $0.4 million from  the  comparative 
period in 2009, primarily due to the increased cash balances. 
The Company had a foreign exchange loss of $0.1 million for the six months ended June 30, 2010, compared to 
a  $0.2 million gain for the six months ended June 30, 2009. Losses recorded in the current year period can 
primarily be attributed to the effect of the Colombian Peso's strengthening against the Canadian dollar  on 
Colombian Peso denominated assets.

Notes and Factors Affecting Comparability of Quarters: 
     1.  The  Company  is a mineral exploration and development company and has no operating  revenue. 
         Interest is from funds on deposit. The amount of interest earned is a function of the amount of funds on 
         deposit and interest rates. Interest rates on term deposits dropped significantly in 2009 and remained low 
         in the first half of 2010. This, however, was offset by the significantly increased levels of cash, which 
         contributed to increasing level of quarterly interest income in 2010 compared to 2009. 
     2.  Stock-based compensation costs are a non-cash expense and represent the amortization  of  the 
         estimated fair value of stock options granted determined using the Black-Scholes option pricing model. 
     3.  Exploration and other project-related activities in Colombia shut down each year for a Christmas 
         break which extends into January. As a result of this shut-down, exploration and project-related 
         expenditures for the December 31 quarter and the March 31 quarter tend to be lower than the preceding 
         September 30 quarter. For the quarter ended December 31, 2008, the reduction in costs for the Christmas 
         break was partially offset by increased costs for the PFS which commenced in August 2008. For the quarters 
         ended March 31, 2009 and June 30, 2009, the reduction of costs can be attributed to the time lag between 
         the completion of the PFS and the start of the FS in late June 2009. For the second half of 2009, costs 
         increased significantly due to efforts being placed on the FS.  Engineering costs for the feasibility study 
         decreased during the first quarter of 2010 but increased in the second quarter. 
     4.  There has been a general trend for increased administrative general costs over the eight quarters. 
         This can be attributed to increased compliance and reporting costs, professional fees, inflation, and a 
         significant increase in staffing at the senior management level during the second half of 2009 and first 
         half of 2010 as the Company anticipates moving into development. 
 
5.  LIQUIDITY AND CAPITAL RESOURCES 
 
Statement of Cash Flow Information 
 
At June 30, 2010, cash and cash equivalents were $116.4 million, up from $81.6 million at December 31, 
2009. The increase in cash and cash equivalents is primarily attributed to the receipt of gross proceeds of 
$75.3 million from equity issuances completed in 2009 and $46.1 million received from the exercise of 
warrants in the first quarter of 2010. 
 
The Company's cash resources are invested in short term financial instruments issued  by  major  Canadian 
chartered banks. These instruments mature at various dates over the current operating period and are 
generally cashable on a designated monthly date. The Company does not invest in asset-backed  commercial 
paper. 
 
Cash used in operations including changes in non-cash working capital was $5.5 million for the three months 
ended  June  30,  2010, compared to $4.6 million for the comparative period in 2009. For the  three  months 
ended June 30, 2010, exploration-related expenditures, including feasibility study costs, were $5.8 million 
and represent the major use of funds for the year. Additionally, $637,100 was allocated to restricted cash. 
Pursuant to the land acquisition agreement, the Company was required to make a progress payment of $637,100 
in  April  2010 for the Las Puentes land parcel it acquired in June 2009. However, certain of the  original 
Las  Puentes  vendors are currently in a title dispute with another unrelated group.  The Company  believes 
that  its title to the Las Puentes land parcel is not at risk, but has placed the $637,100 progress payment 
into an escrow account pending settlement of the title dispute amongst the vendors and the unrelated group. 
The Company expects this dispute to be settled within the next 12 months. 
 
Cash  used in operations including changes in non-cash working capital was $10.3 million for the six months 
ended  June 30, 2010, compared to $7.7 million for the comparative period in 2009. For the six months ended 
June  30, 2010, exploration-related expenditures, including scoping and feasibility study costs, were  $9.2 
million  and  represent the major use of funds for the year. Additionally, $0.6 million  was  allocated  to 
restricted cash as noted above. 
 
At  June  30, 2010, the Company had working capital of $112.0 million, but had not yet achieved  profitable 
operations  and  expects to incur further losses in the development of its business.  For  the  six  months 
ended  June  30,  2010, the Company reported a net loss of $14.8 million and as at June 30,  2010,  had  an 
accumulated  deficit  of $152.0 million.  The ability of the Company to continue  as  a  going  concern  is 
dependent  upon  the  Company's  ability to arrange additional funds to complete  the  development  of  its 
property and upon future profitable operations. 
 
Management  of  the  Company  believes  that the current level of funds  will  be  sufficient  to  pay  for 
anticipated project and administrative costs to the end of 2010. Financial advisors have been appointed  to 
assist  the  Company in developing a financing plan for development of the Angostura project. However,  the 
current  economic  uncertainty and financial market volatility make it difficult to predict  success.  Risk 
factors  potentially  influencing the Company's ability to raise equity  or  debt  financing  include:  the 
outcome  of  the  Company's  application for an environmental permit with the MAVDT,  mineral  prices,  the 
results  and  recommendations of the FS, the political risk of operating in  a  foreign  country,  and  the 
buoyancy of the credit and equity markets. For a more detailed list of risk factors, refer to the Company's 
Annual  Information Form for the year ended December 31, 2009, which is filed on SEDAR. Management  intends 
to continue discussions with potential debt and equity investors. 
 
Due  to  the  current low interest rate environment, interest income is not expected to  be  a  significant 
source  of  income or cash flow.  Management intends to monitor spending and assess results on  an  ongoing 
basis and will make appropriate changes as required. 
 
Commitments 
 
There  have been no significant changes to the Company's commitments as of June 30, 2010.  For full details 
on  commitments, refer to the Company's audited financial statements and notes and MD&A for the year  ended

8.      CRITICAL ACCOUNTING ESTIMATES 
 
Mineral Property and Land Costs 
 
It  is the Company's accounting policy that exploration and development expenditures incurred prior to  the 
determination of the feasibility of mining operations are charged to operations as incurred. The  Company's 
mineral property account on the balance sheet reflects actual costs incurred by it on acquisition costs  of 
its properties. The realization of the Company's investment in these exploration projects is dependent upon 
various  factors, including the discovery of economically recoverable reserves of minerals, the ability  to 
obtain  necessary  financings to develop the  project's potential, upon future  profitable  operations,  or 
alternatively  upon  the disposal of interests on an advantageous basis. The Company reviews  the  carrying 
values  of  its projects on a quarterly basis and if required, makes an adjustment to reflect the project's 
realizable  value.  Capitalized costs will be amortized over the estimated useful life  of  the  properties 
following  the  commencement of production. As at June 30, 2010, amounts capitalized to mineral  properties 
total $19.1 million. 
 
Amounts Payable on Mineral Property Acquisition 
 
Included  in  the  Company's  balance sheet is the fair value of the amounts payable  on  mineral  property 
acquisition.  The  fair  value  of the amounts payable on mineral property acquisition  was  determined  by 
discounting  the  stream  of  future  cash payments at the estimated prevailing  market  rate  for  a  debt 
instrument of comparable maturity and credit quality. Changes in assumptions can materially affect the fair 
value estimate, and therefore, the existing models do not necessarily provide a reliable single measure  of 
the fair value. 
 
Asset Retirement Obligation 
 
The  asset  retirement  obligation  has  been estimated based on the Company's  interpretation  of  current 
regulatory  requirements and have been measured at fair value. Fair value is determined based  on  the  net 
present   value   of  expected  future  cash  expenditures  upon  reclamation  and  closure.  Environmental 
rehabilitation  costs  are  charged to exploration costs. Because the fair value measurement  requires  the 
input  of  subjective assumptions, including the environmental rehabilitation costs, changes in  subjective 
input assumptions can materially affect the fair value estimate. 
Income taxes 
 
Future income tax assets and liabilities are computed based on differences between the carrying amounts  of 
assets  and liabilities on the balance sheet and their corresponding tax values using substantively enacted 
income  tax rates at each balance sheet date. Future income tax assets also result from unused loss  carry- 
forwards  and  other  deductions.  The valuation of future income tax  assets  is  reviewed  quarterly  and 
adjusted, if necessary, by use of a valuation allowance to reflect the estimated realizable amount. 
 
Fair value of stock-based compensation and warrants issued 
 
The  fair value of stock-based compensation and warrants issued are subject to the limitation of the Black- 
Scholes  option pricing model that incorporates market data and involves uncertainty in estimates  used  by 
management in the assumptions. Because the Black-Scholes option pricing model requires the input of  highly 
subjective  assumptions, including the volatility of share price, changes in subjective  input  assumptions 
can materially affect the fair value estimate. 
 
9.      NEW ACCOUNTING POLICIES 
 
(a)     Business Combinations 
 
In October 2008, the CICA issued CICA Handbook Section 1582, "Business Combinations", which establishes new 
standards recognition, measurement, presentation and disclosure of business acquisitions. This standard  is 
substantially  aligned  with International Financial Reporting Standards. This is  effective  for  business 
combinations  for  which  the acquisition date is on or after the beginning of the first  annual  reporting 
period  beginning on or after January 1, 2011.  Should the Company engage in a future business combination, 
it  would  consider  early  adoption  to coincide with the adoption of  International  Financial  Reporting 
Standards.  The  Company  is currently assessing the impact of this accounting standard  on  the  Company's 
financial position and results from operations. 
 
(b)     Non-controlling Interests 
 
In October 2008, the CICA issued CICA Handbook Sections 1601, "Consolidated Financial Statements" and 1602, 
"Non-controlling  Interests", which provide revised guidance on the presentation of consolidated  financial 
statements and accounting for non-controlling interests subsequent to a business combination. This guidance 
is  effective  for fiscal years beginning on or after January 2011. The Company is currently assessing  the 
impact of this accounting standard on the Company's financial position and results from operations. 
 
(c)     International Financial Reporting Standards ("IFRS") 
 
In February 2008, the AcSB confirmed that 2011 is the changeover date for publicly- listed companies to use 
IFRS.   The  date is for interim and annual financial statements relating to fiscal years beginning  on  or 
after  January 1, 2011.  The transition date of January 1, 2011, will require our 2010 comparatives  to  be 
presented according to IFRS. 
 
Key dates: 
    *   January 1, 2010 (transition date): An opening statement of financial position according to IFRS 
        will be prepared as at this date to facilitate the changeover to IFRS in 2011. The Company will continue to 
        report its fiscal 2010 and comparative 2009 results according to Canadian GAAP. 
    *   January  1, 2011 (changeover date): The date after which the Company will prepare  and  report 
        interim and annual 2011 financial statements with 2010 comparatives according to IFRS. 
 
While  the  Company continues to perform detailed assessments of the impact of adopting IFRS, the following 
has  been  identified as key areas where the Company expects differences. However, the full impact  of  the 
transition to IFRS cannot be reasonably estimated at this time. 
        (a)     Functional currency. The Company will assess the principal currency of the economic environment in 
                which the Company operates. 
        (b)     Measurement and presentation of warrant liability. The Company will assess the measurement and 
                presentation of its warrants based on the outcome of the functional currency assessment. 
        (c)     Valuation and classification of the Company's mineral properties. Assessment of the classification 
                of mineral properties as intangible or tangible as appropriate and assessment for impairment when 
                facts and circumstances suggest that the carrying amount may exceed its recoverable amount. 
        (d)     Recognition and measurement of stock-based compensation. Assessment of the fair value of each 
                vesting tranche of stock options  at the date of grant and their related amortization. 
        (e)     Measurement of asset retirement obligation. Inputs used for measurement such as interest rate and 
                estimates of costs will be assessed. 
 
 
10.     OFF BALANCE SHEET ARRANGEMENTS 
 
The Company has no off-balance sheet arrangements. 
 
 
11.     OUTSTANDING SHARE DATA 
 
The  Company  has  only one class of share capital, common shares without par value. The number  of  shares 
authorized is unlimited. The Company has issued warrants for the purchase of common shares and also  has  a 
stock option plan. 
 
The following are outstanding at August 11, 2010: 
 
Common shares                                                                  84,203,697 
Shares issuable on the exercise of warrants                                     3,235,686 
Shares issuable on the exercise of outstanding stock options                    6,764,365 
 
 
12.     RISKS AND UNCERTAINTIES 
 
The  Company  competes  with  other mining companies, some of which have greater  financial  resources  and 
technical  facilities, for the acquisition of mineral concessions, claims and other interests, as  well  as 
for the recruitment and retention of qualified employees. 
 
The  Company  is  in  compliance in all material respects with regulations applicable  to  its  exploration 
activities.  Existing and possible future environmental legislation, regulations and  actions  could  cause 
additional  expense, capital expenditures, restrictions and delays in the activities of  the  Company,  the 
extent  of  which cannot be predicted. In particular, the development of the Angostura gold-silver  project 
may  be  materially affected by the outcome of the Company's application for an environmental  permit  with 
MAVDT.   Before  production  can  commence  on any properties,  the  Company  must  obtain  regulatory  and 
environmental approvals. There is no assurance that such approvals can be obtained on a timely basis or  at 
all.  The  cost  of  compliance with changes in governmental regulations has the potential  to  reduce  the 
profitability of operations. 
 
The  Company's mineral property is located in Colombia. The Company is subject to certain risks,  including 
currency fluctuations and possible political or economic instability which may result in the impairment  or 
loss of mining title or other mineral rights, and mineral exploration and mining activities may be affected 
in varying degrees by political stability and governmental regulations relating to the mining industry. The 
acquisition  of mining title in Colombia is a very detailed and time-consuming process. In addition,  title 
to mining rights may be disputed. 
 
The  Company has incurred losses since its inception and will not achieve profitability until such time  as 
the Angostura Project can be developed into a profitable operation.

Information Form for the year ended December 31, 2009, which can be found on SEDAR at www.sedar.com. 
 
 
13.     INTERNAL CONTROL OVER FINANCIAL REPORTING 
 
Disclosure Controls and Procedures 
 
Disclosure  controls and procedures are designed to provide reasonable assurance that information  required 
to  be  disclosed  by  the  Company under Canadian Securities laws is recorded, processed,  summarized  and 
reported within the time periods specified under those laws and include controls and procedures designed to 
ensure  such  information  is  accumulated and communicated to management, including  the  Chief  Executive 
Officer  ("CEO")  and  the  Chief Financial Officer ("CFO"), to allow timely decisions  regarding  required 
disclosure. 
There  has been no change in the Company's disclosure controls and procedures during the three months ended 
June  30, 2010, that has materially affected or is reasonably likely to materially affect the purposes  set 
out above. 
 
Internal Controls over Financial Reporting 
 
Management is responsible for the establishment, maintenance and testing of adequate internal controls over 
financial  reporting to provide reasonable assurance regarding the reliability of financial  reporting  and 
the  presentation  of  financial  statements for external purposes in accordance  with  Canadian  generally 
accepted accounting principles. 
 
The  Company's  management  and  the  Board of Directors do not expect that  its  disclosure  controls  and 
procedures or internal controls over financial reporting will prevent all errors or all instances of fraud. 
A  control  system,  no matter how well designed and operated, can provide only reasonable  (not  absolute) 
assurance that the control system's objectives will be met. 
 
Further,  the  design, maintenance and testing of a control system must reflect the  fact  that  there  are 
resource constraints and the benefits of controls must be considered relative to their costs. 
 
Because  of the inherent limitations in all control systems, no evaluation of controls can provide absolute 
assurance  that  all  control  gaps and instances of fraud have been detected. These  inherent  limitations 
include the reality that judgment in decision-making can be faulty, and that simple errors or mistakes  can 
occur.  Controls can also be circumvented by the individual acts of some persons, by collusion  of  two  or 
more  people, or by management override of the controls. The design, maintenance and testing of any  system 
of  controls  is  based  in part upon certain assumptions about the likelihood of future  events,  and  any 
control system may not succeed in achieving its stated goals under all potential future conditions. 
 
There has been no change in the Company's internal control over financial reporting during the three months 
ended  June  30,  2010,  that has materially affected, or is reasonably likely to  materially  affect,  the 
Company's internal controls over financial reporting. 
 
 
14.     FORWARD LOOKING STATEMENTS 
 
Certain  statements  included or incorporated by reference in this MD&A, including information  as  to  the 
future  financial  or  operating performance of the Company, and its projects,  constitute  forward-looking 
statements.  The  words  "believe",  "expect", "anticipate", "contemplate",  "target",  "plan",  "intends", 
"continue",  "budget",  "estimate",  "may", "will", "schedule" and similar  expressions  identify  forward- 
looking  statements.  Forward-looking  statements include, among other  things,  statements  regarding  the 
estimation of mineral resources, success of exploration activities, currency fluctuation, the future  price 
of  gold  and silver, governmental regulation of mining operations, and estimated gold recoveries. Forward- 
looking statements are based upon a number of estimates and assumptions made by the Company in light of its 
experience  and  perception of historical trends, current conditions and expected future  developments,  as 
well  as  other factors that Greystar believes are appropriate in the circumstances. While these  estimates 
and  assumptions  are  considered  reasonable by the Company, they are inherently  subject  to  significant 
business,  economic, competitive, political and social uncertainties and contingencies. Many factors  could 
cause  the  Company's actual results to differ materially from those expressed or implied in  any  forward- 
looking  statements made by, or on behalf of, the Company. Such factors include, among  other  things,  the 
outcome  of  the  Company's application for an environmental permit with the MAVDT, risks relating  to  the 
Company's ability to obtain adequate financing for the development of the Angostura Project, conclusions of 
economic evaluations; changes in project parameters as plans continue to be refined; future prices of  gold 
and silver, possible variations in ore reserves, grade or recovery rates; risks related to fluctuations  in 
the  currency  market,  risks related to the business being subject to environmental laws  and  regulations 
which  may increase costs of doing business and restrict the Company's operations; risks relating to  title 
disputes;  risks  relating to all the Company's properties being located in Colombia, including  political, 
economic  and  regulatory instability, accidents, labour disputes and other risks of the  mining  industry; 
delays in obtaining governmental approvals or financing or in the completion of development or construction 
activities. These factors and others that could affect Greystar's forward-looking statements are  discussed 
in  greater  detail in the section headed "Risk Factors" in the Company's Annual Information Form  for  the 
year  ended  December 31, 2009, which can be found on SEDAR at www.sedar.com. Investors are cautioned  that 
forward-looking  statements  are  not  guarantees of future performance  and,  accordingly,  investors  are 
cautioned not to put undue reliance on forward-looking statements due to the inherent uncertainty  therein. 
Forward-looking  statements are made as of the date of this MD&A, or in the case of documents  incorporated 
by reference herein, as of the date of such document, and the Company disclaims any intent or obligation to 
update  publicly such forward-looking statements, whether as a result of new information, future events  or 
results or otherwise.
