VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 24, 2011) - 
 
NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES 
 
Nautilus Minerals (TSX:NUS)(AIM:NUS) has launched a marketed public offering of common shares of the 
Company. 
 
The offering will be conducted through a syndicate of underwriters led by TD Securities Inc. and 
Credit Suisse Securities (Canada), Inc. 
 
The offering is expected to raise gross proceeds of approximately C$150 million. The Company also will 
grant the underwriters an over-allotment option to purchase up to that number of additional common 
shares equal to 15% of the common shares sold pursuant to the offering. The option will be exercisable 
for a period of 30 days following closing. 
 
The Company intends to use the net proceeds from the offering to fund the development of the Solwara 1 
project, to fund the Company's equity contribution associated with the production support vessel joint 
venture agreement and for general corporate purposes. 
 
Final pricing of the offering will be determined in the context of the market prior to the filing of 
the final short form prospectus. The common shares will be offered in all provinces of Canada except 
Quebec by way of a short form prospectus and other jurisdictions outside of Canada pursuant to 
applicable private placement exemptions. 
 
This press release shall not constitute an offer to sell or the solicitation of an offer to buy nor 
shall there be any sale of the securities in any state of the United States in which such offer, 
solicitation or sale would be unlawful. The securities have not been registered under the U.S. 
Securities Act of 1933, as amended, and may not be offered or sold in the United States absent

Cautionary Statements 
 
Certain of the statements made in this news release may contain forward-looking statements within the 
meaning of applicable Canadian and United States Securities law. Forward-looking statements and 
information include, but are not limited to statements or information with respect to the expected 
gross proceeds of the offering and the use of the net proceeds from the offering. We have made 
numerous assumptions about the material forward-looking statements and information contained herein, 
including among other things, the costs associated with the development of the Solwara 1 project, the 
maintenance of a successful joint venture partnership with Harren and the ability of the Company to 
raise funding in the financial markets. Even though our management believes that the assumptions made 
and the expectations represented by such statements or information are reasonable, there can be no 
assurance that the forward-looking statements or information will prove to be accurate. Forward- 
looking statements and information by their nature involve 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 statements or information. Such risks, uncertainties and 
other factors include, among others, a change in the expected use of proceeds, the failure to complete 
the offering or to obtain the approval of the TSX, Harren or Nautilus failing to secure debt funding, 
the Nautilus Board of Directors failing to sanction the project, late delivery of the support vessel 
or other equipment, variations to the price of the vessel, and assumptions regarding exchange rates. 
Should one or more of these risks, uncertainties or other factors materialize, or should underlying 
assumptions prove incorrect, actual results may vary materially from those described in forward- 
looking statements and information. Although we have attempted to identify factors that would cause 
actual results to differ materially from those described in forward-looking statements and 
information, there may be other factors that cause actual results, performances, achievements or 
events to not be as anticipated, estimated or intended. Also, many of the factors are beyond our 
control. There can be no assurance that forward-looking statements or information will prove to be 
accurate, as actual results and future events could differ materially from those anticipated in such 
statements. Accordingly you should not place undue reliance on forward-looking statements or 
information. 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.
