Companies back moratorium on deep sea mining

April 5, 2021 — A long-running dispute over plans to start mining the ocean floor has suddenly flared up.

For years it was only environmental groups that objected to the idea of digging up metals from the deep sea.

But now BMW, Volvo, Google and Samsung are lending their weight to calls for a moratorium on the proposals.

The move has been criticised by companies behind the deep sea mining plans, who say the practice is more sustainable in the ocean than on land.

The concept, first envisaged in the 1960s, is to extract billions of potato-sized rocks called nodules from the abyssal plains of the oceans several miles deep.

Rich in valuable minerals, these nodules have long been prized as the source of a new kind of gold rush that could supply the global economy for centuries.

Interest in them has intensified because many contain cobalt and other metals needed for the countless batteries that will power the electric vehicles of a zero-carbon economy.

British Columbia seeks bids for cleanup of mine polluting Alaska waters

December 5, 2018 — British Columbia mining regulators have taken the first step toward paying to clean up an abandoned mine that has been leaking acid runoff into Alaska waters for decades.

The British Columbia Ministry of Energy, Mines and Petroleum Resources issued a request for proposals Nov. 6 soliciting bids to remediate the Tulsequah Chief mine in the Taku River drainage about 10 miles upstream from the Alaska-British Columbia border.

State officials contend the multi-metal mine that operated for just six years has been leaking acid wastewater into the Tulsequah River, which feeds the Taku, since it was closed in 1957.

The Taku River empties into the Pacific near Juneau and is one of the largest salmon-bearing rivers in Southeast Alaska.

The Alaska congressional delegation and former Gov. Bill Walker’s administration have stepped up their demands for provincial officials to address the situation in recent years — largely at the behest of Southeast commercial fishing and Native groups — after the mine’s latest owners, Toronto-based Chieftain Metals Ltd., began bankruptcy proceedings in 2016.

Sen. Dan Sullivan and former Lt. Gov. Byron Mallott traveled to Ottawa to meet with Canadian officials in February to discuss their environmental and fishery concerns about government oversight of mining activity within transboundary watersheds in the province that flow into Alaska.

A burst of mining activity in the remote northern region of the province has led to numerous new mines and mine proposals in transboundary watersheds.

At the same time, the Energy, Mines and Petroleum Ministry has come under scrutiny for its regulatory requirements of mines after a British Columbia auditor general report concluded the 2014 Mount Polley mine tailings dam breach was the result of inadequate engineering.

The Mount Polley copper and gold mine is in the upper reaches of the large Fraser River watershed.

Alaska officials have also requested their provincial counterparts assist in conducting baseline environmental studies in the lower reaches of transboundary watersheds to monitor things such as water quality in advance of upstream mine development.

Sullivan said in a Nov. 19 statement from his office that he is encouraged the provincial government has finally taken a more active role in cleaning up the troubled and abandoned mine.

“The announcement that the government intends to move forward and develop a remediation plan is a step in the right direction. As voices on both sides of the border have been asking for years, it’s time for the B.C. government, the state of Alaska, Alaska Native and First Nations communities to work together to remove this and other looming threats over our rivers, fisheries, communities’ health and wellbeing,” Sullivan said.
