Health considerations of mining within the Rainy River Watershed, the geographic region at the headwaters of the Boundary Waters Canoe Area Wilderness, Ontario's Quetico Park, and Voyageurs National Park are examined, and the broader effects to public health as well as benefits of existing wilderness are recognized. Abstract Sulfide-ore copper nickel …

Leaving aside the impending shortage of Class 1 nickel, mining inevitably has an impact on an asset's surroundings. The International Council on Mining and Metals (ICMM) has defined a set of Mining Principles aimed at maximizing the benefits to local communities, while minimizing the negative impacts. Although part of this impact will be ...

The sulfide mining necessary to obtain these minerals releases toxins into the air and water. This is especially true of mines situated in wet environments like Tamarack, which is part of the Mississippi River watershed, which in turn is an important wildlife habitat and source of water for millions in the Twin Cities and states to the south. ...

Sulfide mining (specifically copper-nickel sulfide mining) represents a significant departure from Minnesota's iron mining tradition. Sulfide mining can produce acid waste and sulfates that mobilize the release of heavy metals into the environment. These metals include known neurotoxins such as lead and mercury.

Moreover, some of sulfide mining's ecological threats can be mitigated or avoided alto- gether. Nevertheless, the decision to allow sulfide mining inevitably is a decision to permit some ecological harm. Whether this harm is worth the anticipated benefits of a mine is a question for policymakers and regulators.

Yet, surprisingly, a new mine is now looming. In 2012, the Chilean company Antofagasta purchased old mining leases and devised a plan to build a sulfide-ore copper mine only five miles from the southern edge of the Boundary Waters. The dangerous project is advancing quickly with government support and could soon compromise this …
