Former U.S. President Donald Trump has ordered the approval of the 211-mile Ambler Road project in Alaska, reopening a major mining route that had been blocked under the Biden administration. The gravel road, stretching through remote wilderness north of Fairbanks, aims to provide access to rich deposits of copper, cobalt, gold, and other critical minerals essential for electric vehicles, renewable energy technologies, and defense manufacturing.
Initially approved during Trump’s first term, the project was halted after environmental reviews found potential harm to caribou habitats and the livelihood of Alaska Native tribes dependent on fishing and hunting. Despite these concerns, the Trump administration has revived the project, citing the need to strengthen domestic mineral production and reduce dependence on foreign supplies.
Interior Secretary Doug Burgum said the Ambler Road approval would “unlock access to minerals critical for winning the AI and energy race against China.” The administration also announced that the U.S. government will take a 10% equity stake in Trilogy Metals, the Canadian company partnering with Australia’s South32 to develop the Ambler mining site.
Environmental and Indigenous groups have voiced strong opposition, warning that the road’s construction—cutting through 26 miles of protected parkland and crossing 11 rivers—could threaten ecosystems and traditional subsistence practices. Many Alaska Native organizations are expected to challenge the decision in court.
Supporters argue the $7 billion copper deposit could generate thousands of jobs and boost U.S. mineral self-reliance. As Trump’s administration moves to reopen resource development on public lands, it marks a sharp policy reversal from Biden’s conservation-focused land management approach.
