Perpetua Resources Jumps 14% After Securing $2.9 Billion EXIM Loan for Idaho Antimony Project
3 articles · Updated · CNBC · May 21
Perpetua Resources rose nearly 14% in after-hours trading after saying it secured a $2.9 billion loan from the U.S. Export-Import Bank.
The financing will fund the Stibnite project in Idaho, a gold mine that will also produce antimony, a metal used in munitions and semiconductor manufacturing.
EXIM had earlier described the package as the largest under its Make More in America initiative, underscoring Washington's push to expand domestic critical-minerals supply.
That strategy aims to cut U.S. reliance on China for key inputs tied to defense, technology and renewable-energy supply chains.

Overview
Perpetua Resources Corp. made strong progress in early 2026 by advancing its Stibnite project in Idaho, following the groundbreaking in late 2025. The company focused on securing a $2.7 billion loan from the U.S. Export-Import Bank (EXIM) through the 'Make More in America' program, which aims to boost domestic production of strategic minerals. By March 31, 2026, significant steps had been taken toward this financing, with a final EXIM vote expected soon. These efforts are key to funding the project’s development and supporting U.S. goals for critical mineral independence and industrial growth.
