The US Department of War is prioritizing the domestic supply of critical metals such as copper, gold, and zinc, and is taking steps to boost investment and infrastructure in the sector, signaling a significant shift in its stance on critical metals.
Strategic Federal Partnership & Permitting Breakthrough
US Department of War invested 5% equity (~$35M) alongside South32 in Trilogy Metals, marking federal government as strategic partner focused on domestic critical metal supply for national defense priorities, significantly de-risking the project through government backing.
Ambler Road permitting breakthrough in October 2025 reinstated the 2020 Trump administration decision, removing the primary infrastructure barrier and enabling expedited permitting pathway for developing high-grade VMS deposits in Northwest Alaska’s Ambler Mining District.
Project Economics & Revenue Diversification
Arctic deposit delivers $4.3B+ after-tax NPV with 54% IRR at current metal prices, with 30% of revenue derived from precious metals (gold and silver), providing significant economic de-risking beyond base metal price exposure in the copper-silver-gold-zinc-lead VMS project.
District-Scale Potential & Historical Context
Ambler Mining District contains 70 years of drilling data (210,000m) with potential for VMS deposit clusters comparable to Flin Flon, Noranda, and Bathurst districts that have produced continuously for up to 80 years with ongoing new discoveries throughout their operational life.
2026 Development Timeline
Trilogy’s 2026 program includes advancing Ambler Road project, conducting additional exploration drilling (condemnation, resource conversion, anomaly follow-up), and commencing permitting and feasibility study work to support final investment decision with federal funding support.
Critical Metals Supply Chain Strategy
High-grade VMS projects strategically positioned to supply domestic US critical metals including copper, zinc, lead, and cobalt, aligning with federal priorities for domestic supply chain security within broader secular bull market for precious and critical metals.
