COEUR D'ALENE, Idaho -- (Business Wire)

Hecla Mining Company (NYSE:HL) ("Hecla", or the "Company") is pleased to announce today that it has completed the sale of its subsidiary that owns the Casa Berardi Mine in Quebec, Canada to a wholly-owned subsidiary of Orezone Gold Corporation (TSX: ORE | ASX: ORE | OTCQX: ORZCF) ("Orezone") per the terms announced on January 26, 2026 (the “Transaction”). Completion of the Transaction further solidifies Hecla's strategic positioning as the premier North American silver producer.

As part of the Transaction, the Company’s direct wholly-owned subsidiary received $160 million in cash and approximately 65.8 million Orezone common shares upon closing and is entitled to receive deferred cash payments and contingent cash consideration of up to $321 million.

Today, the Company also announced the delivery of a notice of full redemption to the holders of its remaining $263 million 7.25% Senior Notes (“Notes”) due 2028. The Notes and the redemption are governed by an indenture by and among the Company, the Guarantors party thereto, and the trustee. The redemption date is scheduled for April 9, 2026. Subject to the terms and conditions of the Indenture, the Notes will be redeemed at par plus accrued and unpaid interest. This news release does not constitute a notice of redemption of the Notes.

This further deleveraging is expected to enhance 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 plans to utilize the cash proceeds from the Transaction closing along with cash on hand to fund the redemption of the Notes and the payment of any accrued and unpaid interest.

"The closure of the Transaction marks a defining moment in Hecla's transformation. We are using the proceeds and cash on hand to redeem the remaining balance of our Notes which materially strengthens our balance sheet," said Rob Krcmarov, President and Chief Executive Officer of Hecla Mining Company. "Combined with our world-class silver assets at Greens Creek, Lucky Friday, and Keno Hill, this financial flexibility positions Hecla to invest in the growth opportunities that should drive long-term value for shareholders. We are a stronger, more focused company — and the premier silver producer in North America."
