The TSX does not accept responsibility for the adequacy or accuracy of this press release.

Certain of the statements made in this news release may contain forward-looking information within the meaning of applicable securities laws, including statements with respect to the Company's funding requirements, expectations to receive additional bridge loans and enter into a credit facility, and the continued development of the Solwara 1 Project. We have made numerous assumptions about such statements; including assumptions relating to the Company’s funding requirements, project funding, and completion and operation of the Company's seafloor production system. Even though our management believes the assumptions made and the expectations represented by such statements are reasonable, there can be no assurance that they will prove to be accurate. Forward-looking  information  by  its  nature  involves  known  and  unknown  risks,  uncertainties  and  other  factors which may cause the actual results to be materially different from any future results expressed or implied by such forward-looking  information. Please refer to our most recently filed Annual Information Form in respect of material assumptions and risks related to the prospects of extracting minerals from the seafloor and other risks relating to the Company's business and plans for development of the Solwara 1 Project. Risks related to continuing the Company's operations and advancing the development of the Solwara 1 Project include the risk that the Company will be unable to obtain at all or on acceptable terms, and within the timeframes required, the remaining financings necessary to fund completion of the build, testing and deployment of the Company's seafloor production system, that the Company will be unable to rectify or arrange for the rectification of the default under the shipbuilding contract for the construction of the Production Support Vehicle (as announced on 11 December 2017) and that agreements with third party contractors for building slots within certain timeframes are not secured as required. As the Company has not completed an economic study in respect of the Solwara 1 Project, there can be no assurance that the Company's production plans will, if fully funded and implemented, successfully demonstrate that seafloor resource production is commercially viable. Except as required by law, we do not expect to update forward-looking statements and information as conditions change and you are referred to the full discussion of the Company's business contained in the Company's reports filed with the securities regulatory authorities in Canada.
