Nautilus Awarded Exploration Tenements in Eastern Pacific 
 
VANCOUVER, BRITISH COLUMBIA--(Marketwire - July 22, 2011) - Nautilus Minerals' (TSX:NUS)(AIM:NUS) Tongan 
subsidiary, Tonga Offshore Mining Ltd. ("TOML"), has become one of the first private sector organizations to be 
granted exploration licences in the highly prospective Clarion Clipperton Zone ("CCZ") of the Eastern Pacific. 
 
Sponsored by the Tongan Government, TOML has been granted approximately 75,000 km(2) of prime exploration 
territory in the CCZ, which lies in international waters between Hawaii and Mexico. 
 
As a result of exploration conducted in the 1980s, the CCZ is known to host significant deposits of 
polymetallic nodules, which are golf ball sized nuggets, rich in copper, nickel, manganese and cobalt, lying on 
the seafloor in water depths starting at 4500 metres. 
 
The International Seabed Authority, which is the organization responsible for administering activity on the 
seafloor in international territory, made the historic decision to grant the TOML licence at its annual meeting 
in Jamaica this week. The licence is for an initial period of 15 years. 
 
Nautilus CEO Steve Rogers said the award of the exploration permit presented exciting opportunities for the 
long term growth and expansion of the company. 
 
"At Nautilus, with our first project at Solwara 1 in the Bismarck Sea, we are adapting technologies to access 
seafloor mineral resources in water depths of 1600 metres. Ultimately, we intend to seek to establish the 
capacity to expand operations to undertake larger scale projects envisaged in the deeper waters of the CCZ. 
 
"Nautilus is pleased to be at the forefront of development, working with industry and the scientific community 
to establish methodologies and processes to develop these significant resources in ways that are socially and 
environmentally responsible," he said. 
 
The ISA previously has awarded eight exploration permits to government entities for polymetallic nodule 
exploration, but has not previously granted licences to private sector organizations. TOML's application for 
exploration permits represented "a new milestone in the life of the (International Seabed) Authority," 
according to ISA Secretary General Nii Allotey Odunton.
