DULUTH, Minn. (AP) - PolyMet Mining Corporation says the environmental review of its proposed copper mining operation near Hoyt Lakes has been delayed again.
The review was expected to be released in October. But the company said Wednesday it won't be ready for publication until the first quarter of 2013.
The revised environmental impact statement has been in the works since 2009, when federal regulators rejected the original. The Duluth News Tribune reports that ongoing efforts to use complex computer modeling to see how the mine would affect air and water appear to be holding up the final report.
PolyMet is proposing Minnesota's first copper-nickel-precious metals mine. It says the $600 million project would create about 350 jobs.
Environmentalists have been critical because of the long history of pollution at other copper mines.
