TORONTO, ONTARIO--(Marketwired - Nov 24, 2016) - Nautilus Minerals Inc. (TSX:NUS)(OTCQX:NUSMF)(OTC:NUSMF Nasdaq Intl Designation) (the "Company" or "Nautilus") is pleased to provide a current update on the build of the Production Support Vessel (PSV). The PSV is to be used by Nautilus and its PNG partner, Eda Kopa (Solwara) Limited, as the base for its seafloor operations planned at the Solwara 1 Project site, in the Bismarck Sea of Papua New Guinea.

Mike Johnston, Nautilus' CEO commented, "The Company is very excited by the progress that continues to be made by the team at the Fujian Mawei Shipyard Ltd (FMSL) and Marine Assets Corporate (MAC). The thruster rooms (aft hull blocks) have just recently been lifted into position on the vessel. The accommodation module construction is progressing rapidly with many blocks being assembled alongside the dry dock. It is expected to be lifted onto the vessel by the end of the month. We are now looking forward to progressing the final build phase and fit out of the vessel with the team at FMSL and MAC."

Certain of the statements made in this news release may contain forward-looking information within the meaning of applicable securities laws. We have made numerous assumptions about such statements, including assumptions relating to the project funding. 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. 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.
