Trilogy Metals Advances U.S. Department of War Investment for Alaska Copper Projects

Trilogy Metals Inc. (NYSE American: TMQ) (TSX: TMQ) has provided an update on its proposed strategic equity investment of approximately US$35.6 million from the U.S. Department of War (DOW) to support exploration and development of the Upper Kobuk Mineral Projects in northwestern Alaska. The company confirmed that discussions with the DOW are ongoing and that the letter of intent signed in October 2025 remains in effect as both parties continue to advance negotiations. This investment is intended to bolster continued exploration and development activities at the project, which is part of the Ambler Mining District, one of the world's richest and most prospective copper-dominant districts.

The significance of this investment cannot be overstated. The Upper Kobuk Mineral Projects, held through Trilogy's 50% interest in Ambler Metals LLC, are positioned to play a critical role in meeting the growing demand for copper and other critical minerals in the United States. Copper is essential for electrification, renewable energy infrastructure, and national security applications. By supporting domestic mining projects, the DOW's proposed investment aligns with broader federal efforts to reduce reliance on foreign sources of critical minerals and strengthen supply chain resilience.

Trilogy Metals' exploration efforts have focused on two key deposits within the Ambler Mining District: the Arctic volcanogenic massive sulfide (VMS) deposit and the Bornite carbonate replacement deposit. These deposits contain copper, zinc, lead, gold, silver, and high-grade copper and cobalt mineralization, making them strategically important for both economic and defense purposes. The land package spans approximately 190,929 hectares, providing ample opportunity for substantial resource development.

The proposed investment would enable Trilogy to accelerate exploration and development activities, potentially bringing these resources closer to production. This could have significant economic impacts for the state of Texas and the nation, as the development of domestic critical mineral sources reduces dependence on imports and creates jobs in mining, processing, and related industries. Furthermore, the project operates under an agreement with NANA Regional Corporation, Inc., an Alaska Native Corporation, ensuring that development is conducted in cooperation with local communities and with respect for subsistence livelihoods.

Trilogy Metals' vision to develop the Ambler Mining District into a premier North American copper producer aligns with the growing emphasis on securing domestic supply chains for critical minerals. The ongoing discussions with the DOW underscore the strategic importance of this project not only to the company but to the national interest. As the world transitions to cleaner energy and advanced technologies, the need for copper and other minerals will only increase, making investments in projects like the Upper Kobuk Mineral Projects vital.
