Hecla Releases 2025 Sustainability Report

COEUR D'ALENE, Idaho--(BUSINESS WIRE)--Hecla Mining Company (NYSE:HL) has released its 2025 Sustainability Report, highlighting the Company’s environmental, social and governance (ESG) performance.

"As Hecla continues its transformation into North America's Premier Silver Company, 2025 proved that purpose and performance are not competing priorities — they are the same priority," said Rob Krcmarov, President and CEO of Hecla Mining Company. "This year, we delivered silver production at the top end of our guidance, achieved a 13% improvement in safety performance, and produced the critical minerals the world needs to power its future — all while strengthening our environmental standards, deepening our indigenous partnerships, and contributing more than $1 billion in direct economic impact to the communities where we operate. The U.S. government's designation of silver as a critical mineral affirms what we have always believed: that responsible, domestic production of silver is strategically essential. With our sustainability policy now in place and our values embedded across every level of the company, Hecla is setting the standard for how responsible mining should be done."
