Northern Dynasty Minerals (TSX: NDM) has cleared the last environmental hurdle for its proposed Pebble copper-gold-molybdenum mine in Alaska almost two decades after developers first started considering the project.
The U.S. Army Corps of Engineers has issued a final environmental impact statement (EIS), backing the controversial mine in the salmon-rich Bristol Bay.
The decision opens the door for Northern Dynasty to obtain the federal go-ahead as soon as late August.
“There is more work to be done, but the publication of the Final EIS today is a clear validation that Pebble can be developed in an environmentally sound and socially responsible way, creating benefits and opportunities for the people of Bristol Bay and all Alaskans,” Ron Thiessen, Northern Dynasty’s president and CEO, said in a statement.
He noted that the final EIS describes the proposed open-pit mine and related infrastructure as an operation that will protect water quality, fisheries, wildlife and other valued natural resources. Based on that, the U.S. Army Corps of Engineers believes the mine can secure all necessary federal and state permits in future.
Opponents of the project didn’t wait to express their discontent.
“The science is overwhelmingly clear: the proposed Pebble Mine is a catastrophe waiting to happen,” said Collin O’Mara, president and CEO of the National Wildlife Federation.
“It’s simply unconscionable to fast-track such a high-risk project with a shoddy environment review that failed to evaluate the consequences should the proposed six-story dam fail and release 10 billion gallons of toxic waste into Bristol Bay’s treasured, pristine ecosystem,” O’Mara noted.
Bonnie Gestring, northwest program director for environmental group Earthworks, was also highly critical. “We are not talking about minor impacts, but the wholesale destruction of over a hundred miles of rivers and streams,” she said in a statement. “No other mine in North America, and perhaps the world, would have such a devastating effect on clean water.”
Tom Collier, chief executive officer of Pebble Partnership, the project developer, said the publication of the Final EIS was the most significant milestone in the project’s history.
“Today was really fifteen years in the making,” he said. “[We have] a project that can be done responsibly, without harm to the Bristol Bay fishery, and provide meaningful contributions to the communities closest to the project.”
Northern Dynasty said that, based on the positive environmental assessment, it would now seek a major mining company to become a partner in the project.
Since Teck Resources’ (TSX: TECK.B; NYSE: TECK) predecessor, Cominco, began exploring the prospect in the 1980s, Pebble has divided conservationists, local activists, fishermen and regulators.
Northern Dynasty secured a 100% ownership in Pebble in 2005. Two years later, it entered into a 50-50 partnership with Anglo American (LSE: AAL) to develop the massive deposit.
The Canadian miner became again the sole owner of Pebble in 2013, after Anglo American walked away from the project, in which it had invested US$573 million.
Pebble’s permitting process has been mired in controversy and delays. Perhaps one of the most publicized issues was the U.S. Environmental Protection Agency’s (EPA) decision in 2014 to propose restricting the discharge of mining waste and other material in the area.
Criticism prompted the Vancouver-based company to submit a new, smaller mine plan that includes lined tailings, and eliminate the use of cyanide in the gold extraction process.
Pebble began moving forward after the election of Donald Trump in November 2016. In July last year, Northern Dynasty scored a big win as the EPA scrapped the proposed restrictions on mining operations in Bristol Bay, which prevented the project’s consideration.
The agency also issued a letter at the time, saying the project may result in substantial and unacceptable impacts to aquatic resources. That observation was a specific step in a sequence established to deal with inter-agency disagreements over Clean Water Act permits.
A draft version of the EIS released in February, however, indicated that the project could coexist with the fisheries and water resources of the Bristol Bay area.
The news was followed in May by the EPA issuing a new letter that downplayed the possible loss of streams and other wetlands the project might cause.
If permitted, Pebble would be North America’s largest mine, with a productive life of at least 20 years.
Headaches for Northern Dynasty, however, may not end up there. A coalition of local residents and national environmental groups has vowed to challenge the permit in court.
There is also the possibility that the next administration blocks it once again, as happened during Obama’s presidency, should Democrats win the White House in the fall.
The current resource estimate includes 6.5 billion tonnes in the measured and indicated categories containing 57 billion lb. copper and 71 million oz. gold, 3.4 billion lb. molybdenum and 345 million oz. silver. The project is 320 km southwest of Anchorage, Alaska.
In a research note, Cantor Fitzgerald mining analyst Mike Kozak described the positive EIS as a “huge de-risking event.”
“The final EIS document is over 2,000 pages, and at this stage we have only been able to review the Executive Summary,” he wrote. “That said, in our view, it clearly outlines that the Pebble mine can be developed and operated in an environmentally benign and sustainable manner.”
“Following the favourable Final EIS, we believe a positive Record of Decision and 404 Wetlands Permit is forthcoming. This should make the Pebble project far more attractive to a broader range of larger-tier partners.”
