Trilogy Metals Strengthens Leadership Following US Government Investment in Alaska Mining Project

Trilogy Metals Inc. (NYSE American: TMQ) (TSX: TMQ) has announced the expansion of its advisory and leadership teams following its October 6, 2025, announcement of a US federal government investment to advance exploration and development of the Upper Kobuk Mineral Projects in northwestern Alaska. These projects are held by Ambler Metals, the company's 50/50 joint venture with South32 Limited. With permitting and project activity expected to accelerate at Ambler Metals, Trilogy is strengthening oversight of the joint venture as South32 increases its personnel commitment, while Ambler Metals recruits key management roles to support execution of its 2026 program.

The company announced the appointment of Egizio Bianchini as strategic advisor and additional management appointments, positioning the company to advance corporate development initiatives and progress toward closing the US government investment in the Upper Kobuk Mineral Projects. This strategic move comes as the company prepares for increased activity in the Ambler Mining District, which is recognized as 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.

The expansion of Trilogy's leadership team is particularly significant given the scale of the Upper Kobuk Mineral Projects, which span approximately 190,929 hectares within the Ambler Mining District. Exploration efforts have been focused on two primary deposits: the Arctic VMS deposit and the Bornite carbonate replacement deposit. Both represent substantial mineral resources that could contribute to North American copper production. The company's vision to develop the Ambler Mining District into a premier North American copper producer while protecting and respecting subsistence livelihoods requires robust leadership and strategic guidance, especially as project activity intensifies.

The timing of these appointments coincides with South32's increased personnel commitment to the joint venture, indicating coordinated efforts between the partners to advance the projects efficiently. Ambler Metals has an existing agreement with NANA Regional Corporation, Inc., an Alaska Native Corporation that provides a framework for the exploration and potential development of the Ambler Mining District in cooperation with local communities. This partnership underscores the importance of community engagement and sustainable development practices in the region.

This leadership expansion represents a critical step in Trilogy Metals' strategy to capitalize on the US government investment and advance the Upper Kobuk Mineral Projects toward production. The strengthened team will be responsible for overseeing the complex permitting processes, managing the joint venture relationship with South32, and executing the ambitious 2026 program outlined for Ambler Metals. As the company moves toward closing the federal investment, these leadership appointments signal Trilogy's commitment to responsible resource development and its preparedness to manage the increased operational demands associated with advancing a major mining project in Alaska's challenging environment.
