President Trump has issued a decision under Section 1106 of the Alaska National Interest Lands Conservation Act, granting permits for the Ambler Access Project and reversing the Biden Administration's June 2024 "No Action Alternative" that had terminated the project's right-of-way grant. The decision came in response to an appeal by the Alaska Industrial Development and Export Authority and directs federal agencies to reinstate and finalize all necessary permits to ensure feasible access to the Ambler Mining District for economic, industrial, and commercial purposes.
The legal foundation for this decision stems from Congress's mandate in Section 1106 of ANILCA that transportation access "shall be granted" to the Ambler Mining District. This provision enabled AIDEA's direct appeal and reaffirms the federal commitment to resource development alongside environmental stewardship in Alaska. The decision represents a significant policy shift from the previous administration's approach to resource development in the region.
The Ambler Mining District, located in northwestern Alaska, is considered one of the richest and most-prospective known copper-dominant districts in the world. The district hosts world-class polymetallic volcanogenic massive sulphide deposits containing copper, zinc, lead, gold and silver, along with carbonate replacement deposits that have been found to host high-grade copper and cobalt mineralization. Exploration efforts have focused on two primary deposits: the Arctic VMS deposit and the Bornite carbonate replacement deposit, both located within a land package spanning approximately 190,929 hectares.
Trilogy Metals Inc., which holds a 50 percent interest in Ambler Metals LLC, stands to benefit significantly from this decision. Ambler Metals maintains a 100 percent interest in the Upper Kobuk Mineral Projects within the Ambler Mining District. The company's joint venture with South32, a globally diversified mining and metals company that exercised its option to form a 50/50 partnership with Trilogy in December 2019, positions the project for potential development.

The decision's implications extend beyond immediate corporate interests, potentially affecting regional economic development, national copper supply chains, and the balance between resource extraction and environmental conservation in Alaska's sensitive ecosystems.
Ambler Metals has established an agreement with NANA Regional Corporation, Inc., an Alaska Native Corporation, providing a framework for exploration and potential development of the Ambler Mining District in cooperation with local communities. This partnership reflects the complex stakeholder landscape involved in Arctic resource development projects, where indigenous rights, environmental concerns, and economic development interests must be carefully balanced.
The reinstatement of the Ambler Access Project permits represents a critical milestone for developing what could become a premier North American copper production hub. With global demand for copper continuing to grow, particularly for renewable energy infrastructure and electric vehicle manufacturing, access to new copper deposits becomes increasingly important for national security and economic competitiveness.
