Toronto-based Nautilus Minerals has announced that it has successfully tested new seafloor mining tools in waters off the coast of Papua New Guinea. Nautilus' seafloor mining system is based on three submerged vehicles that operate in concert. A so-called 'auxiliary cutter' prepares the terrain for a more powerful 'bulk cutter,' which transfers excavated minerals to a 'collecting machine' that ferries material to surface ships. Completing the trials in PNG allowed Nautilus to work closely with its partner Petromin, government officers from the various government regulatory agencies, as well as representatives from provincial governments of New Ireland and East New Britain. It also gave community leaders from coastal villages geographically closest to the 'Solwara 1' test site the opportunity to witness the trials of the equipment.
