How Hecla is Addressing the United Nations Sustainable Development Goals

In 2025, we achieved a 13% improvement in safety, driving our premium operational performance and underscoring our commitment to responsible mining.
In 2025, Hecla held its second company-wide, tools-down Safety Day, pausing all operations to enable everyone to focus on their approaches to safety.
Hecla developed updates to the Safety and Health Policy to reflect our new Safety 365 values and associated commitments.

In 2025, 42 Hecla leaders participated in our company-wide Leadership Training program, reflecting our commitment to developing confident, values-aligned supervisors across all operations.
Hecla provided a range of support for students and schools, such as hosting mine tours, collecting and donating school supplies to the Juneau School District, and contributing $10,000 for the Juneau Symphony Strings Camp. We organize career fairs and other educational opportunities such as sponsoring students in mining programs and offering internships.

At Lucky Friday, Hecla engineers are undertaking an ambitious project to dramatically reduce the volume of water discharged into the South Fork of the Coeur d’Alene River.
At Greens Creek, we began using dissolving flocculent blocks to remove additional sediments from water before discharging it into the environment.
At ERDC, we advanced the design and construction of water treatment facilities to ensure proper treatment before discharging water into the environment or to municipal plants.

All operating mine sites get a majority of their electricity from renewable sources, predominantly hydropower.
Hecla is continually looking for opportunities to improve our intake of renewable energy and reduce our intake of carbon-intensive energy sources.

As part of our recruitment strategy, we have developed relationships with universities’ mining schools to engage with candidates for operational and technical roles. We also work with local universities to recruit candidates for positions in accounting, human resources, and information technology.
When seeking to fill open positions, we prioritize local hiring as part of our corporate responsibility and social obligation to the communities where we operate. As of December 31, 2025, 84% of our senior managers were local to their communities.
In 2025, Hecla contributed more than $289 million to our local communities through wages, bonuses, and severance.

Our efficiency tools include an Emissions-Based Maintenance (EBM) program that uses emissions data to determine whether equipment is running most efficiently or requires maintenance. This program has been fully implemented at Greens Creek.
As part of our enterprise risk management processes, we incorporate climate-related risks and opportunities into our risk management and strategic planning processes aligned with the TCFD framework. We periodically conduct structured high-level risk assessments (HLRAs). Our expanded approach includes a climate-related physical risk assessment, which was conducted in 2022 to identify and monitor potential exposure to material climate-related risks.

In 2025, Hecla secured 53 abandoned mine lands at our Aurora site with fencing, berms, and signage. This allows bats and other animals to still use the shafts as habitat while protecting humans and large wildlife.
At our closed facility in Troy, Montana, we have had a more than 90% revegetation success rate, even on steep alpine slopes.
Hecla maintains approximately $224 million in guaranteed outside bonds to ensure that closure and reclamation occur at all of our sites. We perform a structured review of company-wide assets and reclamation obligations on a quarterly basis to ensure appropriate plans and financial accruals are in place, and our Audit Committee provides a report on the review to our Board of Directors.
