The Trump administration says the Pebble Mine won’t cause major environmental harm - Washington Post.

"Trump officials will conclude Friday that a proposed gold and copper mine in Alaska — which would be North America’s largest — would not pose serious environmental risks, a sharp reversal from a finding by the Obama administration that it would permanently harm the region’s prized sockeye salmon."

"In a final environmental analysis obtained by The Washington Post, the U.S. Army Corps of Engineers found that Pebble Mine, which targets a deposit of gold, copper and other minerals worth up $500 billion, “would not be expected to have a measurable effect on fish numbers” in the Bristol Bay watershed that supports the world’s largest sockeye salmon fishery."
