Hecla Mining — May 5, 2026 release

Such forward-looking statements may include, without limitation: (i) at Greens Creek, the Company’s organic growth initiatives consisting of the pyrite concentrate circuit and the dry‑stack tailings reprocessing project, which may generate additional marketable concentrates, increase silver and gold recoveries, reduce reclamation liabilities, expand underground mineral reserves, complete metallurgical test work (including Phase 3 test work scheduled for mid‑2026), achieve relatively low capital intensity to reach a cash‑flowing state, and support future project updates, including updates expected in late 2026 or early 2027; (ii) the Midas restart project has the potential to reduce the capital required to restart the operation through its fully permitted infrastructure, with Midas representing a potential hub-and-spoke operating model where ore sources could come from multiple regional sources fed into the 1,200 tpd mill, and the Company working to expand the existing high-grade gold and silver resource to the scale needed to warrant that restart, with regular exploration updates throughout 2026; (iii) the surface cooling project at Lucky Friday is expected to be completed by mid-2026; (iv) at Keno Hill, (a) silver grade mined and milled is expected to increase in the second quarter as mine sequencing improves and high-grade stopes develop; and (b) achieving 440 tons per day, its permitted capacity, remains the medium-term objective, requiring completion of key infrastructure investments and amendments to the Company’s Quartz Mining License and Water License, a multi-year process; (v) capital investment is expected to ramp up in the second quarter with the warmer construction months and remain elevated in the third quarter as numerous projects are advanced across the portfolio; (vi) exploration activity is planned to ramp up in the second and third quarters, with core drills expected to increase from 13 to 19, the 2026 Nevada drill program targeting follow-up of high-grade gold intercepts at Midas with Hollister drilling scheduled to begin late in the second quarter, and the Keno Hill program planned to complete approximately 80,000 feet of drilling focused on resource expansion; and (vii) the reaffirmation of previously issued guidance with respect to production and costs. The material factors or assumptions used to develop such forward-looking statements or forward-looking information include that the Company’s plans for development and production will proceed as expected and will not require revision as a result of risks or uncertainties, whether k
