Nautilus Minerals Project Update

TORONTO, ONTARIO--(Marketwired - Nov. 10, 2016) - Nautilus Minerals Inc. (TSX:NUS)(OTCQX:NUSMF)(OTC:NUSMF Nasdaq Intl Designation) (the "Company" or "Nautilus") is pleased to announce that Factory Acceptance Testing (FAT) of the Riser Tooling and the Subsea Pull-in Skids, was successfully completed this week in Poland and the USA respectively.

Mike Johnston Nautilus CEO commented, "Completion of the Riser Tooling and all the Subsea Pull-in Skids is a significant milestone for the Project. The final piece of the subsea mineralization delivery system is the Subsea Slurry and Lift Pump, and we look forward to taking delivery of this from GE Oil & Gas by the end of the year."

Riser Tooling

The riser tooling, which was designed by GMC in Houston, is a key piece of equipment that will be used for handling and coupling the 19 meter riser joints together for deployment. It was manufactured and underwent successful FAT in Poland.

The ridged riser system is an integral part of the Nautilus seafloor recovery system. It allows the mineralized material to be transferred from the seafloor up onto the Production Support Vessel without any interaction between the different water layers within the ocean, resulting in a very small environmental footprint.

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 taking delivery of the SSLP later this year. 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. 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.
