The sulfide-ore copper mining industry has a disastrous track record. A peer-reviewed report prepared by Earthworks studied fourteen sulfide-ore copper mines representing 89% of current U.S. copper production. Of those fourteen mines, all had experienced some sort of pipeline spill or other accidental release.

The mining of copper/nickel sulfide ores is a toxic type of mining that is risky to our environment, our workers and communities, and local economies. Mining sulfide rock releases acid and toxic metals and contaminants that pollute rivers and groundwater for hundreds of years, long after the profits are spent and the products buried in landfills.
