As the global demand for metals surges and the U.S. government turns to Alaska for secure critical mineral supply, a renewed sense of purpose is taking place in America’s Last Frontier. With prices rising for minerals like copper, silver and gold, and federal momentum building behind domestic production, Alaska’s mining sector has entered a new era of growth since the election. 

Alaska is exceptionally rich in critical mineral potential; of the U.S. government’s 60 designated critical minerals, at least 50 are found within the state, positioning Alaska as a cornerstone of America’s strategy to secure domestic supply chains for essential resources. From the copper, zinc and cobalt-rich Ambler Mining District – home to world-class deposits, Alaska’s mineral endowment is both vast and diversified.

Trilogy Metals Inc. (NYSE American: TMQ) (TSX: TMQ), a company focused on developing its high-grade copper assets in the Ambler Mining District, recently marked significant steps forward in both infrastructure and investment support. On the same day that President Trump issued a decision to grant the permits for the Ambler Road, the U.S. Department of War (“DOW”) invested $35.6 million to acquire a 10% stake in Trilogy, highlighting the importance of the district’s mineral resources. Trilogy, through its Ambler Metals joint venture with South32 Limited, controls a 471,800-acre mineral land package, including the district’s two most advanced deposits: Arctic and Bornite. Together, these deposits host copper, zinc, lead, gold, silver and cobalt (ibn.fm/etZJm).

Led by Alaska’s state-owned corporation, the Alaska Industrial Development and Export Authority (“AIDEA”), the state has prioritized the advancement of the Ambler Access Project, a proposed 211-mile industrial road designed to connect the mineral-rich Ambler Mining District to Alaska’s broader transportation network. With federal permits for the road now executed, the project represents a key milestone in positioning Alaska as a national leader in responsible resource development.

With Alaska emerging as a critical hub for domestic mineral production, Trilogy Metals stands at the forefront of unlocking the state’s vast resource potential. As the joint venture owner of Ambler Metals which is developing the Ambler Mining District’s most advanced deposits, Arctic and Bornite, Trilogy is strategically positioned to deliver the metals essential to the United States’ clean energy, defense, and technology sectors.
