Trump Administration Reinstates Ambler Access Project Permits, Reviving Critical Alaska Mining Corridor
President Trump's decision to grant permits for the Ambler Access Project overturns the Biden administration's previous rejection, ensuring transportation access to one of the world's richest copper-dominant mining districts and reinforcing federal commitment to Alaska resource development.
Trilogy Metals Inc. (NYSE American: TMQ) (TSX: TMQ) announced that President Trump issued a decision under Section 1106 of the Alaska National Interest Lands Conservation Act, granting permits for the Ambler Access Project. The decision upholds an appeal by the Alaska Industrial Development and Export Authority to reverse the Biden Administration's June 2024 "No Action Alternative," which had terminated the project's right-of-way grant. President Trump directed federal agencies to reinstate and finalize all necessary permits to ensure feasible access to the Ambler Mining District for economic, industrial, and commercial purposes.
Under Section 1106 of ANILCA, Congress mandated that transportation access "shall be granted" to the district, enabling AIDEA's direct appeal and reaffirming the federal commitment to resource development alongside environmental stewardship in Alaska. The Ambler Mining District represents one of the richest and most-prospective known copper-dominant districts globally, hosting world-class polymetallic volcanogenic massive sulphide deposits containing copper, zinc, lead, gold and silver, along with carbonate replacement deposits featuring high-grade copper and cobalt mineralization.
Trilogy Metals holds a 50 percent interest in Ambler Metals LLC, which maintains 100 percent interest in the Upper Kobuk Mineral Projects spanning approximately 190,929 hectares in northwestern Alaska. The company's partnership with South32, established through a 50/50 joint venture formed in December 2019, combines resources to develop this strategically important mineral district. Exploration has concentrated on two primary deposits: the Arctic VMS deposit and the Bornite carbonate replacement deposit, both positioned to become significant North American copper production centers.
The reinstated access project enables critical infrastructure development necessary for transporting minerals from this remote region to market. Ambler Metals maintains an agreement with NANA Regional Corporation, Inc., an Alaska Native Corporation, providing a framework for exploration and potential development in cooperation with local communities.

This presidential decision carries substantial implications for domestic mineral supply chains, particularly for copper and cobalt essential for renewable energy technologies, electric vehicles, and national security applications. The Ambler Mining District's development aligns with broader efforts to strengthen United States mineral independence while creating economic opportunities in Alaska. The regulatory certainty provided by this decision enables continued investment in exploration and development activities that had been stalled under the previous administration's position.
