US Army Corps Approves Stibnite Gold Project Construction Permit in Idaho

The U.S. Army Corps of Engineers' Walla Walla District has approved a Clean Water Act Section 404 permit allowing Perpetua Resources to discharge dredged or fill material during the construction of the Stibnite Gold Project in central Idaho, marking the final federal permit needed to advance the project toward construction. This permit follows an extensive multi-year environmental review but does not authorize mining operations, which remain subject to further approvals, including the U.S. Forest Service's finalization of the company's plan of operations. The Stibnite Gold Project is expected to produce significant economic benefits, including approximately 550 jobs and over $1 billion in economic impact, while also providing the only U.S. source of military-grade antimony, a critical mineral for national security. Environmental groups and the Nez Perce Tribe have opposed the project due to concerns over impacts on water quality, wildlife, and tribal lands, leading to legal challenges. Perpetua Resources emphasizes the project's rigorous scientific review and its designed environmental restoration efforts, including improving water quality and wetlands, aiming to balance responsible development with environmental protection. The company is now focused on securing remaining state permits and financing to begin construction.
