Perpetua Resources antimony project funding surges to $474mn

Perpetua Resources

Perpetua Resources antimony project secured an extra $49mn in July. After June financings, Perpetua Resources antimony project totals $474mn. The fresh capital supports construction of Idaho’s Stibnite project.

Financing details and permitting momentum

National Bank of Canada and BMO bought 3.7mn shares for $49mn. Earlier, they purchased 24.6mn shares for $325mn. Paulson & Co. added a $100mn private placement. The company also secured its final federal permit in April. Therefore, capital and permitting now align for execution.

Strategic supply implications and next steps

Stibnite contains 148mn pounds of antimony reserves. China suspended antimony exports to the United States in December. The United States produced no marketable antimony in 2024. As a result, the Perpetua Resources antimony project can cut import dependence. Antimony supports defense, flame retardants, and lead-alloy batteries. Perpetua will deploy proceeds to early works and procurement. Meanwhile, pacing will track prices, logistics, and workforce availability. Therefore, disciplined spend and clear milestones will sustain momentum.

The Metalnomist Commentary

This raise narrows America’s antimony gap as geopolitics tighten supply. Watch offtake timing, early-works progress, and cost control through 2026.
