This page is part of our public exclusion list — a transparency tool that shows which companies we screen out and why. It is not investment advice, and it is not an accusation. But it is subject to change as our understanding of the facts evolves.
Hecla Mining Company is a primary silver producer and a leading U.S. producer of critical minerals, deriving its revenue from the extraction of precious and base metals. The company operates mines in Alaska, Idaho, and Mexico, with its Greens Creek and Lucky Friday mines producing silver, zinc, and other metals.
The company has a documented history of regulatory violations and environmental liabilities linked to its extractive operations. In 2015, the Mine Safety and Health Administration (MSHA) proposed penalties against Hecla Limited for flagrant violations. Furthermore, Hecla Mining Company has been held liable by a federal court for costs related to the Bunker Hill Superfund Site, a legacy mining contamination area, under a consent decree with the United States. The company's own regulatory filings acknowledge that past or ongoing violations could jeopardize its existing operating permits.
Hecla Mining Company has been penalized for environmental violations at multiple active mine sites. In June 2023, the company was fined $143,000 by environmental regulators for hazardous waste management violations at its Greens Creek Silver Mine in Alaska. More recently, in May 2024, a Yukon judge fined Hecla's Keno Hill mining operations $100,000 for problems that put the environment at risk.
The company is also responsible for legacy contamination. In July 2025, Hecla entered a consent decree to settle a cost recovery and natural resource damage action related to the Bunker Hill Mining and Metallurgical Complex Superfund Site. This legal resolution addresses historical environmental damage from mining operations.

The Naughty List
A digest of changes to our exclusion list — new additions, removals, and the evidence behind them. We review the list continuously as new evidence surfaces.
Companies appear on our exclusion list based on our investment judgment — not because they've done anything illegal. This is a difference of values and opinion, not an accusation of wrongdoing. Exclusion does not constitute a recommendation against investing in any company, and absence from the list does not constitute a recommendation to invest.
