Environmental Management

Hecla’s responsibilities expand beyond producing critical metals, and we recognize the importance of creating a positive impact on the environments of the communities where we live and work. We are committed to minimizing the environmental footprint of our operations through continuous improvement of our processes.

Tracking Progress Fosters Accountability

At the center of Hecla’s approach to mining is a commitment to protecting the environment, both globally and at the local level of our operations. All of our sites implement programs to reduce freshwater and energy consumption, protect wildlife and habitats, reduce our carbon footprint, maintain local water quality, and rehabilitate the land once mining is complete.

We track our environmental data to benchmark Hecla’s operations against industry standards, and we report on progress against our goals to ensure accountability and transparency.

Our Environmental Policy

Our Environmental Policy mandates compliance with all applicable federal, state, provincial, and local environmental laws and regulations that govern our facilities, and we go beyond these regulations when they do not meet Hecla’s standards. Where appropriate, rigorous environmental standards and protocols for many environmental issues are applied at all of our operations, including those outside of the U.S. and Canada, to ensure a consistent, high standard of responsible mining.

Management System

We utilize an Environmental Management System (EMS) to encourage companywide consistency in our environmental programs and promote a culture of environmental awareness, innovation, and accountability across all our operations. We track our environmental data to benchmark Hecla’s operations against industry standards, and we report on progress against our goals to ensure accountability and transparency.

In 2025, employees companywide completed more than 4,616 hours of environmental training, focusing on job specific environmental awareness, hazardous material management, spill response, and reporting.

The EMS program is benchmarked against ISO-14001:2015. We conduct an annual internal audit of the EMS at each site, as well as an external audit every three years.

“[Hecla’s] first-class approach serves today—and will continue to serve in the future—as a classic example of how modern mine reclamation can and should be done.”
