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 bridge financing, the use of proceeds of the bridge financing, the restructuring plan, and plans to develop the seafloor mining industry. We have made numerous assumptions about such statements, including assumptions relating to the bridge financing, project funding, completion and operation of the Company's seafloor production system and assumptions regarding the timing and effect of the restructuring plan, including securing agreements with third parties to complete the construction of the remaining seafloor production system within certain timeframes. 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 advancing towards production include the risk that the Company will be unable to obtain at all or on acceptable terms the remaining financing necessary to fund completion of the build, testing and deployment of the Company's seafloor production system 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. Risks related to the restructuring plan include the risk that the plan cannot be implemented as expected, the risk that the plan does not result in the cost savings expected and the risk that the restructuring plan and the bridge financing do not provide sufficient time for the Company to secure project financings for the Solwara 1 Project. 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.
