(Graphic: Business Wire)<\/p>\n<\/div>\n HIGHLIGHTS<\/b><\/p>\n \n“Hecla’s silver reserves stand at 240 million ounces, the second-highest level in our 134-year history and only 1 million ounces below our peak in 2022,” said Rob Krcmarov, President and CEO. “Our 2024 exploration program continued to deliver exceptional results at both Keno Hill and Greens Creek while Keno Hill reserves grew by over 17% and silver production was nearly replaced at Greens Creek. These achievements position Hecla for continued growth as the largest silver producer in the U.S. and Canada and lay the foundation for sustained future growth.”<\/p>\n \nKurt Allen, Vice President of Exploration, commented on the exploration success: “The 2024 drilling program has significantly advanced our understanding of the high-grade mineralization controls at both Keno Hill and Greens Creek. At Keno Hill, the Bermingham Footwall and Main Vein zones continue to deliver exceptional silver grades over mineable widths and remain open for expansion. The emerging cluster of high-grade silver values beneath the Bermingham Deep Northeast Ore Zone is particularly exciting, suggesting proximity to a new ore-shoot that will be a key focus of our 2025 drilling program. At Greens Creek, the strong results from the West Zone and 5250 Zone support our view that this world-class deposit continues to hold significant exploration potential.”<\/p>\n EXPLORATION HIGHLIGHTS BY PROPERTY<\/b><\/p>\n \nSelect drill highlights from the company\u2019s exploration programs include the following drill holes, additional drill holes and details are included later in this release.<\/p>\n Keno Hill (Yukon Territory)<\/b><\/p>\n Bermingham Vein Zone \u2013 Notable Intercepts<\/i><\/p>\n Operational Context:<\/i><\/p>\n \nUnderground definition drilling continued to expand mineralization in the high-grade Bermingham Bear Zone Veins, while surface exploration focused on new discoveries.

Underground drilling completed 7,100 feet, concentrating on resource conversion and expansion of the high-grade Bermingham Bear Zone Veins. Concurrent surface exploration deployed five core drills to complete 28,000 feet across multiple promising targets including the Bermingham Deep, Elsa 17-Dixie, Inca, and Hector-Calumet areas (Figure 1).<\/p>\n \nDefinition drilling in the Bear Zone veins yielded significant results, particularly in the Footwall and Main Veins where high-grade mineralization was extended both at depth and along strike. While drilling in the Bear Vein identified narrow vein mineralization between the Ursa and Arctic faults, the most substantial gains came from the Footwall and Main Veins, where strong high-grade intercepts significantly expanded the known mineralized zones. Both the Footwall and Main Vein zones remain open at depth, with further drilling planned for the first half of 2025 to test their expansion potential. Assay highlights include (reported widths are estimates of true width):<\/p>\n \nSurface exploration drilling delivered exciting results from both the Bermingham system and Inca Vein target areas.<\/p>\n \nAt Bermingham, drilling intercepted significant mineralization across multiple veins, highlighted by an 11.3-foot intersection in the Footwall Vein grading 11.1 oz\/ton silver with associated base metals. This intercept, located beneath the northeastern edge of the Bermingham Deep Northeast Ore Zone, suggests proximity to a new ore-shoot controlled by an interpreted vein intersection. The area is slated for follow-up drilling in 2025.<\/p>\n \nAt the Inca Vein target, initial drilling has outlined over 800 feet of mineralized strike length, delivering exceptional results including 22.3 feet grading 18.1 oz\/ton silver, 16.1% zinc, and significant indium values. The zone remains open for expansion in all directions, demonstrating strong potential for resource growth. The best intercept included 14.3 feet grading 26.1 oz\/ton silver and 20.9% zinc, with notable indium credits of 7.0 oz\/ton.<\/p>\n Greens Creek, Alaska<\/b><\/p>\n \nAt Greens Creek, two underground drilling rigs completed 27 drillholes, totaling 17,083 feet. Definition drilling was focused on resource conversion and exploration and resulted in extending mineralization from known resources. Underground definition drilling targeted the 9A, East, and Gallagher zones and exploration targeted the Gallagher Zone (Figure 5). Assay results were received during the quarter from the 5250, 9A, Gallagher, West, 200S, and UPP zones.<\/p>\n \nUnderground definition drilling delivered mixed but overall positive results across multiple zones. At the Gallagher Zone, four drillholes across two sections encountered elevated alteration, with 61% of received assays from 23 holes expected to positively impact the resource. Highlights from this drilling include:<\/p>\n \nDuring the quarter, assay results for the 5250 Zone were received for 22 drillholes, targeting 13 cross-sections, of which 41% are expected to have a positive impact on the resource. Highlights from this drilling include:<\/p>\n \nDuring the quarter, assay results for the West Zone were received for 15 drillholes, targeting eight cross-sections, of which 40% are expected to have a positive impact on the resource. Highlights from this drilling include:<\/p>\n \nThe 9A Zone drilling campaign successfully established important continuity across several gaps within the zone. Highlights from this drilling include:<\/p>\n \nDetailed drill assay highlights can be found in Table B at the end of the release.<\/p>\n ABOUT HECLA<\/b><\/p>\n \nFounded in 1891, Hecla Mining Company (NYSE: HL) is the largest silver producer in the United States and Canada.
