Nautilus First Quarter Results 
 
VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 15, 2011) - Nautilus Minerals Inc. (TSX:NUS)(AIM:NUS) 
made significant progress in the development of its pioneering seafloor resource project at Solwara 1, 
in the Bismarck Sea of PNG, in the first quarter of 2011. 
 
The highlights of the quarter were as follows: 
 
/T/ 
 
   (1)  Mining Lease Granted. In January, the PNG Government granted 
        Nautilus the first Mining Lease in the Pacific region to allow deep 
        sea resource development in the Bismarck Sea. The lease provides 
        Nautilus with a 20 year licence to mine an area of approximately 59 
        km2 surrounding Solwara 1, 30 km north of Rabaul, where Nautilus 
        intends to mine high-grade copper and gold deposits on the seafloor, 
        at depths of approximately 1600 metres. 
 
   (2)  PNG Government acquires 30% interest in Solwara 1 project. On March 
        29, 2011, the PNG Government exercised an option to acquire a 30% 
        stake in Nautilus' Solwara 1 project. The State's share will be held 
        through Petromin PNG Holdings Ltd., which holds the State's mining 
        and petroleum assets. The State's initial payment to secure its 30% 
        holding will be approximately US$20-25 million, which represents its 
        share of the exploration and development costs incurred up to the 
        date of grant of the mining lease in January 2011. The final amount 
        will be determined through an audit process, with payment to be made 
        by August 1, 2011. In future, Petromin will contribute funds to the 
        Solwara 1 project in proportion to its ownership interest. 
 
   (3)  Exploration drilling campaign conducted. During the quarter, an 
        exploration drilling campaign was conducted in the Bismarck Sea in 
        Papua New Guinea with encouraging results. As part of the 2010/2011 
        drilling program another potential development project has been 
        identified at Solwara 12, which is 25 km to the northwest of Solwara 
        1. The drilling program was completed in May 2011. Results of the 
        program are currently being assessed and will be released later this 
        year. 
 
   (4)  Strong cash position maintained. Nautilus completed the quarter with 
        a strong cash position, holding $139 million in cash and cash 
        equivalents. Two milestone payments were made for engineering and 
        construction of Seafloor Production Tools during the quarter, and 
        additional cash drawdowns were associated with the exploration 
        campaign.

Since the end of the quarter, the Company has announced the formation of a strategic partnership with 
German shipping company, Harren & Partner, to own and operate a Production Support Vessel (PSV), which 
will serve as the operational base for Nautilus to extract high grade copper and gold at the Solwara 1 
project. 
 
On 24th May 2011, Nautilus launched a marketed public offering of common shares. The Company received 
a positive response from investors during marketing of the proposed transaction but adverse market 
conditions meant that it was not in the interests of shareholders for the transaction to proceed and 
on 10th June, the offering was withdrawn. The Company will evaluate a range of alternative options 
available to it to access capital in the future. 
 
CEO Steve Rogers said the first quarter had seen a number of important milestones achieved for 
Nautilus. 
 
"The granting of the Mining Lease was a major step forward for us, and we also were very pleased to 
welcome the PNG Government as a partner in this important project. The subsequent formation of the 
Harren joint venture has secured a state of the art vessel for the project. 
 
"Nautilus has now developed significant momentum. We are looking at alternative capital raising plans 
and look forward to announcing the results of our exploration campaigns in the coming months," said 
Mr. Rogers. 
 
The Company has today released its unaudited consolidated financial results for the first quarter 
ended March 31, 2011 together with Management's Discussion and Analysis. 
 
The Financial Statements and Management's Discussion and Analysis have been filed on www.sedar.com and
