Ambler Metals Assembles Expert Team for Alaskan Critical Minerals Push

VANCOUVER, BC – February 23, 2026 – Trilogy Metals and its joint-venture partner South32 are signaling a major push to transition their massive Alaskan mineral prospect from exploration to development, announcing a slate of high-powered management appointments at Ambler Metals LLC. The new team is tasked with navigating the formidable technical, regulatory, and social landscape of Alaska’s remote Ambler Mining District to unlock what is believed to be one of the world’s richest undeveloped copper-dominant mineral belts.

Ambler Metals, the 50/50 joint venture advancing the Upper Kobuk Mineral Projects (UKMP), has brought on four seasoned executives with specific expertise in Arctic exploration, complex project finance, federal permitting, and Alaskan community relations. The strategic hires are seen as a critical step toward a final investment decision on the flagship Arctic Project and developing the broader district into a premier domestic source of minerals essential for national security and the green energy transition.

Tony Giardini, President and CEO of Trilogy Metals, emphasized the targeted nature of the appointments. "These appointments position Ambler Metals to deliver on critical near-term milestones," Giardini stated in the announcement. He noted the team provides "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."

A Specialized Team for a Complex Challenge

The new leadership team reflects the multifaceted challenges of building a modern mine in the Arctic. Each appointee brings a resume seemingly tailor-made for the hurdles ahead.

• Michael Galicki, the new Vice President of Exploration, joins from partner company South32. His experience managing remote, helicopter-supported exploration programs is considered vital for the upcoming drilling season, which aims to expand the already vast resource base.

• Cole Schaeffer takes the role of Vice President, Human Resources, Community and Partnerships. His deep roots in Alaska, including leadership roles at Teck Resources' Red Dog Mine and with Alaska Native Corporations like Kikiktagruk Inupiat Corporation, are crucial. Giardini highlighted Schaeffer's "deep understanding of community engagement and operational requirements in Alaska’s Arctic," a key factor for a project that must coexist with local subsistence lifestyles and honor its partnership with the NANA Regional Corporation.

• Jenna Tan, appointed Vice President, Finance, brings a track record of steering major mining ventures through feasibility and development, most notably South32’s Hermosa project in Arizona. Her financial and commercial acumen will be tested as Ambler advances the technically complex and capital-intensive Arctic Project toward a final investment decision.

• Ron Rimelman has been named Senior Director, Permitting. With 40 years of experience, including navigating the environmental review for Alaska's Donlin Gold and Red Dog Mine expansion projects, his expertise is paramount. Giardini specifically pointed to Rimelman’s experience with the FAST-41 expedited federal permitting process, which Ambler Metals hopes will streamline the path to approval.

From Paper to Production: The Arctic and Bornite Deposits

The new team's focus is the UKMP, a sprawling 190,929-hectare land package hosting two world-class deposits: Arctic and Bornite. Combined, they hold an estimated resource of 8 billion pounds of copper, 3 billion pounds of zinc, and 1 million ounces of gold equivalent.

The Arctic deposit is the more advanced of the two. A 2023 Feasibility Study outlined a robust open-pit mine with a 13-year life, projecting a pre-tax Net Present Value of $1.5 billion. Ambler is now focused on the geotechnical and condemnation drilling needed to finalize mine design and submit permit applications.

The nearby Bornite deposit, meanwhile, offers the potential for a multi-generational mining district. A 2025 Preliminary Economic Assessment envisioned a 17-year underground operation that could come online after Arctic, potentially extending the UKMP's total operational life beyond 30 years and leveraging the infrastructure built for the first mine.

However, the project's viability hinges on more than just the ore in the ground. Both deposits are located in a remote wilderness, hundreds of miles from existing infrastructure. Their development is entirely dependent on the construction of the proposed 211-mile Ambler Access Road, a controversial, state-supported industrial road project that faces legal and environmental opposition. While permits were granted in 2025, the road's final approval and construction remain the single largest variable in the project's timeline.

Balancing Riches with Responsibility

Developing the Ambler Mining District is a high-stakes balancing act. On one side is the immense economic potential: the Arctic project alone is projected to create over 1,000 jobs and contribute hundreds of millions of dollars to the state. For the NANA Regional Corporation, which has partnered with Trilogy since 2011, it represents a vital opportunity for shareholder employment and regional economic development.

On the other side are profound concerns about the impact on the pristine Arctic ecosystem and the traditional subsistence lifestyles of the region's Indigenous communities. Opponents of the Ambler Access Road worry about its effects on caribou migration, water quality, and hunting and fishing access. The appointment of Cole Schaeffer is a clear signal that Ambler Metals understands the critical importance of its social license to operate and its relationship with NANA and local communities.

Simultaneously, Ron Rimelman's role in permitting will be a key test of the FAST-41 process. This federal framework, designed to streamline reviews for major infrastructure projects to a two-year target, is intended to provide predictability. Navigating this process successfully while satisfying the stringent requirements of the National Environmental Policy Act (NEPA) and the Clean Water Act will be a monumental task, even for a veteran of Alaska's regulatory landscape.

A Strategic Imperative for the Nation

The push to develop the Ambler district is occurring against a backdrop of a global scramble for critical minerals. Copper, cobalt, and zinc are indispensable for the transition to a low-carbon economy, forming the backbone of electric vehicles, wind turbines, and grid infrastructure. The International Energy Agency forecasts that copper demand could double by 2040 to meet climate goals.

This has elevated the UKMP from a regional economic project to a matter of U.S. national and economic security. Washington has shown direct interest in securing domestic supply chains to reduce reliance on foreign nations. A binding letter of intent for a potential $17.8 million investment in Trilogy from a U.S. government entity, contingent on the Ambler road's progress, underscores the project's strategic importance.

The newly assembled leadership team at Ambler Metals is now charged with realizing this potential. Their success will not only determine the future of a multi-billion-dollar mining venture but also test the nation's ability to balance its strategic resource needs with its environmental commitments and its responsibilities to the communities of the Far North.
