On October 6, 2025, Hecla Mining Company announced that the U.S. Forest Service issued the final decision notice and finding of no significant impact for its 100 % owned Libby Exploration Project in Lincoln County, Montana. The approval removes a major environmental hurdle and allows the company to advance the exploration phase of a world‑class copper‑silver deposit. The decision was reached through the FAST‑41 permitting process, which streamlines federal approvals for critical mineral projects.
As of December 31, 2024, the Libby Project contains an inferred resource of 112.2 million tons grading 0.7 % copper and 1.6 ounces per ton silver, translating to over 1.5 billion pounds of copper and 183 million ounces of silver. This resource profile underscores the project’s potential value and aligns with Hecla’s strategy to develop high‑grade, low‑risk assets in North America. The company has expressed openness to partnering with a strategic partner while maintaining its economic exposure to the deposit.
The U.S. Forest Service’s finding of no significant impact is a critical regulatory milestone that enables Hecla to gather essential geological, hydrological, and environmental data needed to evaluate the full potential of the deposit. By clearing this environmental hurdle, Hecla positions itself to accelerate exploration activities, potentially leading to future development and production. The approval also signals continued support from federal agencies for critical mineral projects, reinforcing the company’s focus on responsible development and community engagement.
