"The Melanesian Spearhead Group put in place a moratorium on deep-sea mining within its member countries’ territorial water in a declaration signed Aug. 24.
Leaders from Fiji, Papua New Guinea, the Solomon Islands, Vanuatu and an alliance of pro-independence political parties known as FLNKS from the French territory of New Caledonia said more research is needed to establish whether mining the seabed below 200 meters (660 feet) is possible without damaging ecosystems and fisheries.
The moratorium ostensibly thwarts the return of Nautilus Minerals, a Canadian company, to Papua New Guinea and its Solwara 1 project in the Bismarck Sea, where it had hoped to mine gold and copper from sulfide deposits on the seafloor.
