"Iron Range Mine Could Pollute Water for Up To 500 Years"

"A proposed copper-nickel mine in northeast Minnesota would generate water pollution for up to 500 years and require billions of dollars in long-term cleanup costs, state regulators have concluded as they near a key stage in the project’s review."

"The mine would require what critics say is essentially perpetual water treatment — a first in Minnesota’s long history of mining — to remove pollutants and heavy metals that would otherwise flow into nearby streams and rivers and eventually Lake Superior, according to a draft environmental impact statement.

The analysis, which regulators expect to release for public review in November, was prepared as part of the state’s review of a mining complex proposed by PolyMet Mining Corp., at a site near Hoyt Lakes."
