Canadian corporation plans to mine gold and copper from Papua New Guinea seafloor

By Oliver Milman / The Guardian

A “new frontier” in mining is set to be opened up by the underwater extraction of resources from the seabed off the coast of Papua New Guinea, despite vehement objections from environmentalists and local activists.

Canadian firm Nautilus Minerals has been granted a 20-year licence by the PNG government to commence the Solwara 1 project, the world’s first commercial deep sea mining operation.

Nautilus will mine an area 1.6km beneath the Bismarck Sea, 50km off the coast of the PNG island of New Britain. The ore extracted contains high-grade copper and gold.

The project is being carefully watched by other mining companies keen to exploit opportunities beneath the waves.

The Deep Sea Mining (DSM) campaign, a coalition of groups opposing the PNG drilling, estimates that 1 million sq km of sea floor in the Asia-Pacific region is under exploration licence. Nautilus alone has around 524,000 sq km under licence, or pending licence, in PNG, Tonga, New Zealand and Fiji.

“PNG is the guinea pig for deep-sea mining,” says Helen Rosenbaum, the campaign’s co-ordinator. “The mining companies are waiting in the wings ready to pile in. It’s a new frontier, which is a worrying development.

“The big question the locals are asking is ‘What are the risks?’ There is no certain answer to that, which should trigger a precautionary principle.

“But Nautilus has found a place so far away from people that they can get away with any impacts. They’ve picked an underfunded government without the regulation of developed countries that will have no way of monitoring this properly.”

The mining process will involve levelling underwater hydrothermal “chimneys”, which spew out vast amounts of minerals. Sediment is then piped to a waiting vessel, which will separate the ore from the water before pumping the remaining liquid back to the seafloor.

The DSM campaign has compiled a report, co-authored by a professor of zoology from University of Oxford, which warns that underwater mining will decimate deep water organisms yet to be discovered by science, while sediment plumes could expose marine life to toxic metals that will work their way up the food chain to tuna, dolphins and even humans.

“There are indirect impacts that could clog the gills of fish, affect photosynthesis and damage reefs,” says Rosenbaum.

Activists also claim that an environmental analysis by Nautilus fails to properly address the impact of the mining on ecosystems, nor explains any contingency plan should there be a major accident.

Wenceslaus Magun, a PNG-based activist, told the Guardian that local fishing communities are concerned about the mining and are planning to challenge the exploration licence.

“We are really concerned because the sea is the source of our spirituality and sustenance,” he said. “The company has not explained to us the risks of deep sea mining. They haven’t responded to my requests for information.”

“The government has turned a blind eye to the concern of its own people. We are mobilising people to raise funds to take this to court and retract Nautilus’ licence.”

  1. Fears have been expressed by critics of the project that not enough research has been carried out to enable convincing conclusions to be drawn on the likely environmental impacts of underwater mining particularly as there is very little knowledge of biological diversity and ecosystems within the deposit areas.
