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 potential funding and restructuring transactions. 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 or other transactions necessary to fund completion of the build, testing and deployment of the Company's seafloor production system; that the Company will be unable to successfully negotiate additional extensions to the maturity date of outstanding loans under its secured loan facility; and that the Company will be unable to arrange for the charter of the production support vessel from the owner of the vessel. As the Company has not completed a prefeasibility study or feasibility 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 bu siness contained in the Company's reports filed with the securities regulatory authorities in Canada.
