Hecla Releases 2022 Sustainability Report

Hecla Mining Company (NYSE:HL) released its 2022 Sustainability Report today, highlighting the Company's environmental, social and governance (ESG) performance and 2023 sustainability targets. The theme of this year's report is Reclamation at Hecla: Past, Present, and Future.

"Our decades of commitment to the environment, communities where we operate and accessibility of our stakeholders have made Hecla a leader in ESG," said Hecla President and Chief Executive Officer Phillips S. Baker, Jr. "Our 2022 report demonstrates that our commitment continues and is even stronger. Examples of results in this year's report include our reclamation work at San Sebastian mine in Durango, Mexico, where we backfilled the pits and are returning the land to community agricultural use; being net zero for carbon emissions for the second straight year; and, most importantly, mining the silver the world needs for renewable energy production."
