VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Feb. 20, 2007) -

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Nautilus Minerals Inc. (TSX VENTURE:NUS) (AIM:NUS) (AIM:NUSR) (the "Company" or "Nautilus") is pleased to announce that it has completed the private placement of Units announced on December 22, 2006 and February 5, 2007 for gross proceeds of C$88.5 million (equal to US$75 million or Pounds Sterling 38 million) (the "Offering").

David Heydon, President of the Company, commented: "The Company is well positioned to execute its business plan, with cash on hand of approximately C$324 million (equal to US$275 million or Pounds Sterling 139 million) which, together with other potential sources of capital, is expected to fund an aggressive exploration program and, subject to timely permitting, to be sufficient to fund the Company into production at its primary project, Solwara 1, in the territorial waters of Papua New Guinea. The Company's funds are planned to be deployed in the detailed design and construction of sub sea mining equipment, including two mechanical miners, power umbilicals, pumps, a 1,800 metre riser pipe and related handling equipment, as well as, subject to permitting, the construction of an on-shore concentrator plant and the acquisition of the necessary land on which to build the plant and port."

Heydon added: "This is the next piece in our business plan, since taking Nautilus public only ten months ago, to develop a low cost base metal mine based on seafloor massive sulphide copper-zinc-gold silver deposits. This financing from North American institutional investors complements the US$99.6 million financings late last year by Anglo American, Teck Cominco and Epion and the US$100 million London based institutional financing earlier this month."

At the closing of the Offering, the Company issued a total of 20,344,850 Units for C$4.35 per Unit (equal to US$3.69 or 187 pence), with each Unit consisting of one common share and one-half of one warrant of the Company. Each whole warrant entitles the holder to purchase one additional common share of the Company at a price of C$5.655 per share prior to February 21, 2009. In the event that the volume weighted average price of the Company's common shares on the TSXV or the TSX exceeds C$6.525 for a period of at least 20 consecutive trading days, Nautilus has the right to give notice to the holders of the warrants that the warrants will expire if not exercised within 30 days, provided that such notice may not be given prior to June 21, 2007.

The Offering was managed by a syndicate of agents led by Salman Partners Inc. and included BMO Capital Markets, GMP Securities L.P., TD Securities Inc., Blackmont Capital Inc., and Westwind Partners Inc. The agents received a 5% cash commission of the gross proceeds of the Offering on the closing and broker warrants exercisable for 368,449 common shares at a price of C$5.655 per share prior to February 21, 2009.

In addition to the four month hold period imposed by applicable Canadian securities laws and the policies of the TSXV which will end on June 21, 2007, all purchasers under the Offering are restricted from selling, transferring, pledging or otherwise trading the shares forming part of the Units and underlying the warrants through the facilities of any stock exchange in Canada or the United Kingdom prior to June 21, 2007.

Application has been made for the 20,344,850 common shares issued in connection with the Offering, and for 10,250 common shares issued as a result of the exercise of certain options, to be admitted to AIM. The common shares are expected to be admitted to trading on February 21, 2007.
