With economics like this you would expect all parties would be rushing PLM. One group has been decidedly cool - friends of the environmental. Polymet proposes to set up shop next door to a protected wilderness area and a watershed flowing in the opposite direction. The project is about six miles from Hoyt Lakes and upstream from Colby Lake, a community water supply. Mining is notorious for leaching mercury and other heavy metals into soil and water. The wetlands next door could be at risk if Polymet fails to properly dispose of tailings and waste water.
