Washington takes ten percent stake in Trilogy Metals

The United States government has completed a thirty-five point six million dollar investment in Trilogy Metals, securing a ten percent ownership position in the company. This financial commitment is designed to advance critical minerals projects located in Alaska, specifically supporting the exploration and development of the Upper Kobuk Mineral Projects. The transaction marks a significant deepening of federal involvement in establishing new domestic sources of copper, zinc and other metals that are vital to national supply chains.

The Upper Kobuk Mineral Projects are held by Ambler Metals, a joint venture formed by Trilogy and the Australian mining group South32. Under the terms of the deal, Trilogy and South32 are expected to split the proceeds and have committed to reinvesting the funds directly into the project. As a result of the new government shareholding, South32’s direct ownership of Trilogy has been diluted from ten point seven percent to six percent. The government is simultaneously backing infrastructure and permitting initiatives intended to unlock the remote Ambler mining district, which covers approximately 190,929 hectares and includes the high-grade Arctic polymetallic deposit and the Bornite carbonate replacement deposit.

Technical reports for the Arctic project outline a thirteen-year mine life with average annual payable production of 149 million pounds of copper and 173 million pounds of zinc. The proposed operation would also yield 26 million pounds of lead, 32,538 ounces of gold and 2.8 million ounces of silver annually. Trilogy added the project to the FAST-41 program in May, a federal initiative aimed at accelerating permitting for major infrastructure and critical minerals projects. The company has submitted its Clean Water Act Section 404 permit application to the US Army Corps of Engineers, identifying this as the only key federal permit required, with other approvals managed by state and local authorities. Trilogy expects the federal permitting process to conclude in late 2028.

Development of the region remains dependent on securing approvals and infrastructure for a remote area. The projects have faced environmental and indigenous opposition, particularly regarding the construction of an access route. President Donald Trump has directed federal agencies to advance permitting for the proposed 340-kilometre Ambler Road, which would provide industrial access to the mineral projects. This follows the previous administration’s decision to block the road over environmental concerns. The Department of War has stated it is committed to facilitating financing for the road in coordination with the State of Alaska and the Alaska Industrial Development and Export Authority. This investment highlights a broader US strategy to use government capital and infrastructure support to reduce reliance on foreign sources for critical minerals.
