Overview
About Perpetua Resources
Perpetua Resources Corp. is a U.S.-focused critical-minerals mining company listed on Nasdaq and the TSX (PPTA), headquartered in Boise, Idaho. The company is developing the Stibnite Gold Project in central Idaho, which hosts the largest known antimony reserve in the United States alongside one of the country’s largest gold deposits. Antimony is a strategic critical mineral essential to defense munitions, flame retardants and solar-panel manufacturing, and Stibnite is projected to supply more than a third of U.S. antimony demand during its early production years while restoring a legacy mine site. The roughly $1.3 billion project received its final federal Record of Decision and began early construction in 2025, targeting commercial production around 2028. Perpetua has secured support from the U.S. Export-Import Bank and a Department of Defense award, and its market capitalization stands in the multi-billion-dollar range.
