Nautilus Minerals receives additional bridge loans

TORONTO, March 05, 2018 - Nautilus Minerals Inc. (TSX:NUS) (OTC:NUSMF) (Nasdaq Intl Designation) (the "Company" or "Nautilus") announces that it continues to arrange bridge loans from Deep Sea Mining Finance Ltd. (the "Lender"), which are expected to form part of a larger secured structured credit facility of up to US$34 million to be provided by the Lender to the Company.

To date the Company has received bridge loans from the Lender totaling US$6,650,000. In conjunction with the most recent advance of US$1,900,000, the Company has issued to the Lender an additional 8,161,512 warrants of the Company (the "Warrants"), for a total of 28,565,291 share purchase warrants issued to the Lender to date. Each Warrant entitles the Lender to purchase one common share of the Company at a price of C$0.17 for a period of five years from the date of issuance of the Warrant.

The bridge loans will assist the Company's immediate working capital requirements and facilitate payments required to continue the development of the Company's seafloor production system to be first utilized at the Company's Solwara 1 Project. The loans bear interest at 8% per annum, payable bi-annually in arrears with a one year maturity date.

The Company will be entitled to pre-pay each loan prior to maturity, by paying 108% of the outstanding principal of the loan plus accrued and unpaid interest. Each loan is represented by a promissory note and will initially be secured against the assets of the Company through a general security agreement. The Lender may subsequently require the loan to be guaranteed by the Company's material operating subsidiaries and secured against the assets of such subsidiaries.

As previously disclosed, the Lender is a private company owned 50% by each of: (i) USM Finance Ltd., a wholly owned subsidiary of USM Holdings Ltd, an affiliate of Metalloinvest Holding (Cyprus) Limited; and (ii) Mawarid Offshore Mining Ltd., a wholly-owned subsidiary of MB Holding Company LLC. As the Lender is controlled by two insiders of the Company, the Lender is a "related party" of the Company and the loan transaction constitutes a "related party transaction" of the Company under MI 61-101 Protection of Minority Security Holders in Special Transactions ("MI 61-101"). The transactions comprising the bridge loans and the Warrants will be exempt from the formal valuation and minority shareholder approval requirements of MI 61-101.

The Company did not file a material change report more than 21 days before the expected closing of this transaction, as the details of the transaction were not finalized until immediately prior to the closing and the Company wished to close the transaction as soon as practicable for sound business reasons.

The Company requires significant additional funding in order to complete the build and deployment of the seafloor production system to be utilized at the Solwara 1 Project by the Company and its joint venture partner (as to 15%), the Independent State of Papua New Guinea's nominee.

There can be no assurances that the Company will be successful in securing the necessary additional financing transactions within the required time or at all. Failure to secure the necessary financing may result in the Company undergoing various transactions including, without limitation, asset sales, joint ventures and capital restructurings.

The Company will provide further updates as circumstances warrant.

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 Company's funding requirements, expectations to receive additional bridge loans and enter into a credit facility, and the continued development of the Solwara 1 Project. We have made numerous assumptions about such statements, including assumptions relating to the Company’s funding requirements, project funding, and 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 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 necessary to fund completion of the build, testing and deployment of the Company's seafloor production system; that the Company will be unable to rectify or arrange for the rectification of the default under the shipbuilding contract for the construction of the Production Support Vehicle (as announced on 11 December 2017); and that agreements with third party contractors for building slots within certain timeframes are not secured as required. 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 business contained in the Company's reports filed with the securities regulatory authorities in Canada.
