Using existing technologies from the offshore oil & gas, dredging and mining industries, Nautilus plans to extract high grade Seafloor Massive Sulphide ("SMS") systems on a commercial scale. Nautilus has been working over the past number of years on the building of the Seafloor Production System. On November 13, 2012, Nautilus announced that Management and the Board of Directors of Nautilus decided to terminate construction of its Seafloor Production System in order to preserve cash. This was as a result of a dispute with the Independent State of Papua New Guinea ("State") over costs that Nautilus says the government is obliged to meet for the project

After three years of rigorous negotiations a commercial resolution to the dispute with the Independent State of Papua New Guinea (the State) for its equity participation in the Solwara 1 Project has been reached, clearing the way to further advance the Solwara 1 Project.

How We Plan to Extract Minerals from the Seafloor


In 2007 the exploration team drilled a 43-101 resource on the Solwara 1 Project using newly developed ROV drills. The resulting high grade copper-gold resource was the world's first Seafloor Massive Sulphide ("SMS") resource statement. In 2010/11 further drilling was conducted at Solwara 1 resulting in an increase in the resource base. Results of the updated resource were as follows (November 25, 2011):
  • Indicated Mineral Resource: 1,030kt @ 7.2% Cu, 5.0 g/t Au, 23 g/t Ag, 0.4 % Zn
  • Inferred Mineral Resource: 1,540kt @ 8.1 % Cu, 6.4 g/t Au, 34 g/t Ag, 0.9% Zn
A copy of the full updated mineral resource estimate can be found here.

The original 43-101 resource report can be found here.

The 2011 Golders Resource update also saw the companies second resource declared for the Solwara 12 project (230K t), some 25km NE of Solwara 1, on EL1324.


The Mining Lease ("ML") application and the development proposal were both submitted to the Government of PNG in Q3, 2008 (October 3, 2008). The ML was granted by the Government of Papua New Guinea on January 17, 2011. (January 17, 2011). The Environmental Permit for the development of the Solwara 1 Project was granted in December 2009, by the Department of Environment and Conservation ("DEC") of Papua New Guinea for a term of 25 years, expiring in 2035 (January 5, 2010).

Nautilus plans to launch additional projects on our extensive tenement holdings across the western Pacific. To prepare for this growth we continue to evaluate technology from the perspective of its application to future production systems. Among the key technology areas that we will continue to evaluate and develop are:
  • Mobile mineralised material transhipment systems to increase flexibility and reduce material handling and transportation costs.
  • Floating concentrator facilities for use at a sheltered near-shore location or ultimately, for offshore/on site application.
  • Improved scale/efficiencies in cutting, gathering and pumping equipment.
  • Equipment adaptations for rougher sea conditions.
