Northern Minnesota's Waters and Forests Threatened by Sulfide Mining and Industrial Expansion

Located between the North Shore of Lake Superior and the Boundary Waters Canoe Area Wilderness, the Arrowhead Region is Minnesota's most loved recreation area and a place that millions visit for rejuvenation. This region faces an unprecedented industrial expansion that is certain to affect the qualities that draw people here. One of the worst threats from this expansion is from the mining of sulfide ores, a particularly harmful type of mining that has not been conducted in Minnesota before. PolyMet Mining's NorthMet Mine, located between Babbitt and Hoyt Lakes, is the first of what may become many sulfide mine proposals. (see PolyMet)

Acid Mine Drainage, PA-DEP

What is Sulfide Mining?

Sulfide ores are ores containing heavy metals (such as copper or nickel) that are bonded to sulfur, forming sulfide minerals. When exposed to air and moisture, a chemical reaction generates sulfuric acid that can leach into the surrounding environment and cause the release of the metals into streams and lakes at levels that are toxic to fish and other aquatic life. (See Video) This phenomenon is known as Acid Mine Drainage. In a surface mine like the one proposed by PolyMet, mining leaves huge piles of waste rock and a huge pit exposed to the elements. Like the ore that has been removed, the waste rock and the pit walls contain sulfide minerals. The potential for Acid Mine Drainage and for contamination of surface and ground water by heavy metals remains for centuries, and even millennia, into the future.

What is the track record for Sulfide Mining

Acid mine drainage has already polluted more than 12,000 miles of rivers and streams and over 180,000 acres of lakes and impoundments in the United States. According to the U.S. EPA, acid mine drainage from coal mining is the leading source of water pollution in the Mid-Atlantic States. Acid Mine Drainage from metal mines in Western states has caused some of the country's largest and most contaminated Superfund sites. Mining companies argue that modern mining methods can protect against Acid Mine Drainage, but they cannot point to a single mine that is more than a few years old that has not resulted in contamination. Because Acid Mine Drainage often takes several years to develop, recent mines that have not yet contaminated nearby waters do not provide proof that these ores can be mined safely.

Extensive and advanced exploration for copper-nickel sulfide mineralization is occurring throughout Minnesota's Arrowhead Region, as well as other parts of the state. Sulfide mining, if allowed, would threaten Minnesota's waters with toxic heavy metal contamination and Acid Mine Drainage (AMD).

!!! ACTION ALERTS !!!

Kawishiwi Building Disposition EA - The Forest Service is proposing to eliminate the historic Kawishiwi Research Station and "K" Lab near Ely and the BWCAW. The USFS Halfway Ranger Station Historic District, which includes the lands and buildings used by the Kawishiwi Research Lab, are slated to be demolished as well. The destruction of these Superior National Forest cultural and scientific landmarks, would pave the way for the impending sulfide mining projects located near the BWCAW. Comments are due by August 10th!

PolyMet Fails "EPA has determined that PolyMet's NorthMet Project DEIS is; Environmentally Unsatisfactory and Inadequate... our review has identified adverse environmental impacts that are of sufficient magnitude that EPA believes the proposed action must not proceed as proposed." From the Department of the Interior "The anticipated environmental impacts of the proposed action are not fully and fairly addressed in the DEIS."
