U.S. Secures Major Financing for Domestic Antimony and Gold Mining

Perpetua Resources has obtained a substantial loan to develop the Stibnite Gold Project in Idaho's Payette National Forest, marking the largest financing under EXIM's "Make More in America" initiative. The project will produce gold alongside antimony, a critical mineral essential for defense applications, semiconductors, and renewable energy equipment. Currently, the U.S. operates no domestic antimony mines, leaving it dependent on imports. China dominates global antimony production and satisfies more than half of American demand. The Stibnite mine is positioned as the only domestic source capable of meeting U.S. weapons-grade antimony requirements, with projected supply of approximately 35 percent of national demand within six years of operation. The financing represents continued federal efforts to strengthen domestic critical mineral production amid supply chain vulnerabilities.
