Neither the TSX nor the OTCQX accepts 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 design and operation of the vessel, the expected timing of completion of the vessel and plans to commence mining in Q1 2018. We have made numerous assumptions about such statements, including assumptions relating to the funding, 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 (the "Project"). With respect to the design and operation of the vessel, the Company is assuming that the vessel will be built and operate according to the Nautilus specifications and on schedule. Risks related to such arrangement include the delay to the delivery of the vessel and a consequent delay to the commencement of mining at the Project site, and the risk that the vessel's systems will not operate as intended due to equipment failures and other general risks associated with marine-based operations. Risks related to advancing the Project towards production in 2018 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 and deployment of the Company's seafloor production system. As the Company has not completed an economic study in respect of the 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.
