Trilogy Metals Announces Expanded Management Team at Ambler Metals Joint Venture to Advance Upper Kobuk Mineral Projects in Alaska

VANCOUVER, BC, Feb. 23, 2026 /CNW/ - Trilogy Metals Inc. (NYSE American: TMQ ) (TSX: TMQ) ("Trilogy Metals", "Trilogy" or the "Company") announced today key management appointments at its 50/50 joint venture with South32 Limited ("South32") – Ambler Metals LLC ("Ambler Metals") – which is advancing exploration and development of the Upper Kobuk Mineral Projects ("UKMP") in northwestern Alaska's Ambler Mining District.

Tony Giardini, President and CEO of Trilogy, commented: "Michael Galicki and Cole Schaeffer bring exactly the expertise we need to advance the UKMP. Michael's proven success managing complex exploration programs in high-logistics North American environments positions us perfectly for this year's drilling season as we work to expand our resource base and test high-priority targets.

"Cole brings invaluable experience from both Alaska Native Corporations and Teck Resources Limited's Red Dog Mine, one of the world's largest zinc operations. His deep understanding of community engagement and operational requirements in Alaska's Arctic will be critical as we advance both the Arctic and Bornite deposits. Together, Michael and Cole strengthen our ability to unlock the full value of this world-class mining district.

"These appointments position Ambler Metals to deliver on critical near-term milestones. Jenna Tan brings the financial and commercial rigor we need as we advance toward an investment decision on the Arctic Project. Her experience leading South32's Hermosa project through feasibility and development gives us proven expertise in managing major mining ventures in the United States.

"Ron Rimelman's 40 years of mine permitting experience, including his leadership on the Donlin Gold project and work throughout Alaska, will be invaluable as we navigate the FAST-41 expedited federal permitting process. Together, Jenna and Ron provide the institutional knowledge and technical expertise needed to transform Ambler Metals from explorer to developer and position this venture as a premier domestic source of critical minerals."
