NEWS RELEASE

Hecla Mining Company Completes Redemption of Senior Notes

Achieves unencumbered balance sheet, unlocking full capital flexibility

COEUR D'ALENE, IDAHO – April 9, 2026 - Hecla Mining Company (NYSE:HL) ("Hecla", or the "Company") is pleased to announce today that it has completed the full redemption of its remaining $263 million 7.25% Senior Notes (“Notes”) due 2028, completing a significant milestone in the Company’s balance sheet transformation. Full redemption of senior notes enhances Hecla’s financial flexibility and capacity to invest in strategic growth investments, positioning Hecla to maximize value from its world-class silver portfolio. The Company utilized the cash proceeds from the recently completed Casa Berardi sale along with cash on hand to fund the redemption of the Notes and the payment of accrued and unpaid interest.

"Retiring our senior notes marks a defining moment in Hecla’s balance sheet transformation - we've fundamentally strengthened our balance sheet and positioned the Company to pursue strategic growth with full financial optionality at a time when silver’s role in the global economy has never been more compelling," said Rob Krcmarov, President and Chief Executive Officer of Hecla Mining Company. "This strategic inflection point with no debt obligations has given us the foundation to pursue growth with discipline and from a position of genuine financial strength."

ABOUT HECLA

Founded in 1891, Hecla Mining Company (NYSE: HL) is the largest silver producer in the United States and Canada. In addition to operating mines in Alaska and Idaho, the Company is ramping up a mine in the Yukon, Canada, and owns a number of exploration and pre-development projects in world-class silver and gold mining districts throughout North America.
