Hecla Mining — Aug 4, 2026 release

o Growth pipeline: Preliminary work on the Greens Creek pyrite concentrate circuit points to potential for incremental annual production of approximately 1.0 to 1.2 million ounces of silver and 10,000 to 15,000 ounces of gold once fully ramped up. Separately, the Greens Creek dry-stack tailings facility currently holds an estimated 51 million ounces of silver and 600 thousand ounces of gold. In Nevada, 2026 exploration investment guidance of $16 million is more than three times the 2025 level with expanded programs at Midas and new programs at Hollister and Aurora. See "Project Pipeline Update" section below for further details. o Exploration: As previously announced on July 29, 2026, drilling extended the high-grade Bermingham Deep trend at Keno Hill toward the historic Hector-Calumet Mine - a past-producer of approximately 96 million ounces of silver - now traceable over 800 feet of strike length. Separately, new high-grade vein discoveries were made at Midas in Nevada.   Rob Krcmarov, President and Chief Executive Officer, said: “Our second quarter results reflect the strength of the platform we have built. We ended the quarter with the strongest balance sheet in the Company's history, and Lucky Friday delivered record quarterly silver production, underscoring the quality of our silver portfolio. I'm also encouraged by our strong safety performance across the operations, which remains a foundation of everything we do. At the same time, our organic project pipeline continues to advance, demonstrating real potential for meaningful value creation and further solidify Hecla's position as North America's premier silver producer."
