Trilogy Metals Secures Federal Investment for $35 Million Program to Advance Alaska's Upper Kobuk Mineral Projects

Trilogy Metals Inc. (NYSE American: TMQ) (TSX: TMQ) has received a significant investment from the U.S. federal government to advance exploration and development of the Upper Kobuk Mineral Projects in northwestern Alaska. The projects are held by Ambler Metals LLC, which represents Trilogy's 50/50 joint venture with South32 Limited, a globally diversified mining and metals company that exercised its option to form the partnership in December 2019. This investment enables the company to strengthen both advisory and leadership teams to drive project execution and deliver long-term value to shareholders.

The company has unveiled the 2026 program and budget for Ambler Metals LLC, along with its own corporate budget for the year. Ambler Metals has approved a substantial $35 million 2026 program specifically aimed at advancing the Upper Kobuk Mineral Projects. These projects are located within the Ambler Mining District, recognized as one of the richest and most prospective known copper-dominant districts globally. The district hosts world-class polymetallic volcanogenic massive sulphide deposits containing copper, zinc, lead, gold, and silver, along with carbonate replacement deposits that have demonstrated high-grade copper and cobalt mineralization.

Exploration efforts have primarily focused on two key deposits within the Ambler Mining District: the Arctic VMS deposit and the Bornite carbonate replacement deposit. Both deposits are situated within an extensive land package spanning approximately 190,929 hectares. The strategic importance of this development extends beyond mineral extraction, as Ambler Metals maintains an agreement with NANA Regional Corporation, Inc., an Alaska Native Corporation that provides a framework for exploration and potential development of the Ambler Mining District in cooperation with local communities.

Trilogy's vision centers on developing the Ambler Mining District into a premier North American copper producer while simultaneously protecting and respecting subsistence livelihoods in the region. The company maintains a comprehensive newsroom where investors can access the latest updates and information relating to TMQ at https://ibn.fm/TMQ. This federal investment and subsequent $35 million program represent significant steps toward realizing this vision, potentially positioning Alaska as a major contributor to domestic copper production and reducing reliance on foreign sources of this critical mineral.

The broader implications of this development extend to national security and economic independence, as copper remains essential for infrastructure, renewable energy technologies, and electrification initiatives. The Upper Kobuk Mineral Projects' advancement through this substantial investment demonstrates growing recognition of the strategic importance of domestic mineral resources. As exploration and development progress, these projects could substantially contribute to meeting increasing demand for copper while creating economic opportunities in northwestern Alaska through responsible resource development that considers both environmental and community impacts.
