Sulfide Mining - Acid Mine Drainage
Mining Without Harm
Sierra Club volunteers have been active in Minnesota mining issues since the founding of the North Star Chapter in 1968. The Reserve Mining water quality lawsuit (asbestos-like fibers in Duluth's drinking water), copper-nickel mining, and taconite plants became issues.
Recently Club volunteers in northern Minnesota have been watching the media reports on new proposals for major mining projects. Reports are dominated by a threat for companies to begin sulfide mining (from which copper, nickel, and other metals are extracted*), a toxic type of mining never done in Minnesota before. It is far more dangerous to the environment than taconite mining. Numerous projects now threaten the region, and are driven by higher metal prices that make the investment more attractive from a business perspective.

Where the Sierra Club Stands: Let's ask for proof, not promises from promoters of metallic sulfide mining in Minnesota's northwoods
A kind of mining new to Minnesota has significant long-term risks of pollution and economic instability. This industry has a poor track record of stewardship and integrity. But solutions such as requiring proof it has been done without harm in a similar climate; protecting pristine natural areas from disturbance; not mining where perpetual treatment of drainage pollution is required; and demanding secure and significant financial assurance for reclamation can help keep our waters clean for future generations.
