U.S. President Donald Trump on Monday ordered approval of a proposed 211-mile road through an Alaska wilderness to allow mining of copper, cobalt, gold and other minerals.
The long-debated Ambler Road project was approved in the first Trump administration, but was later blocked by the Biden administration after an analysis determined the project would threaten caribou and other wildlife and harm Alaska Native tribes that rely on hunting and fishing.
The gravel road and mining project, north of Fairbanks, Alaska, “is something that should’ve been long operating and making billions of dollars for our country and supplying a lot of energy and minerals,” Trump said at an Oval Office ceremony.
Former President Joe Biden “undid it and wasted a lot of time and a lot of money, a lot of effort. And now we’re starting again. And this time we have plenty of time to get it done,” Trump added.
In a related development, the White House announced it is taking a 10% equity stake in Trilogy Metals, a Canadian company that is seeking to develop the Ambler site.
Trilogy Metals CEO Tony Giardini says the U.S. government interest underscores the importance of his company’s operations in northwestern Alaska.
The transaction remains subject to regulatory and other approvals.

The U.S. government said last week it is taking a minority stake in Lithium Americas, another Canadian company that is developing one of the world’s largest lithium mines in Nevada. The Department of Energy will take a 5% equity stake in the company and a 5% stake in the Thacker Pass lithium mining project, a joint venture with General Motors.
U.S. Interior Secretary Doug Burgum said approval of Ambler Road will unlock access to copper, cobalt and other critical minerals “that we need to win the AI arms race against China.”
Supporters, including Alaska’s congressional delegation, have said the road is needed to reach a large copper deposit worth more than $7 billion. Copper is used in production of cars, electronics and even renewable energy technologies such as wind turbines.
Opponents, including a consortium of 40 federally recognized tribes, worry that development allowed by the road would put subsistence harvests at risk because the lands include important habitat for salmon and caribou.
The two-lane gravel road includes about 26 miles that would cut through Gates of the Arctic National Park and Preserve, requiring a federal permit. The road would also cross 11 rivers and thousands of streams before reaching the site of a future mine.
The Republican-controlled House approved a bill last month that would pave the way for Trump to expand mining and drilling on public lands in Alaska and other states. The vote, largely along party lines, would repeal land management plans adopted in the closing days of Biden’s administration that restricted development in large areas of Alaska, Montana and North Dakota.
Biden’s goal was in part to reduce climate-warming emissions from the burning of fossil fuels extracted from federal land. Under Trump, Republicans are casting aside those concerns as they open more taxpayer-owned land to development, hoping to create more jobs and revenue and boost fossil fuels such as coal, oil and natural gas. The administration also has pushed to develop critical minerals, including copper, cobalt, gold and zinc.
While Trump has often said, “drill, baby, drill,” he also supports “mine, baby, mine,” Burgum said. “We’ve got to get back in the mining business.”
Trump’s order finds that the proposed road is in the public interest, given U.S. needs for domestic critical minerals, and says there is no economically feasible alternative route.
The decision directs the federal Bureau of Land Management, National Park Service and U.S. Army Corps of Engineers to reissue necessary permits to construct the road.
