“But questions remain on the potential pollution from mining on the edge of the Boundary Waters,” via Star Tribune.

The company that controls mining rights to 32,000 acres on the doorstep of the Boundary Waters Canoe Area said Tuesday that the land contains 19 percent more copper, gold and palladium than it previously estimated, making Minnesota home to one of the world’s largest deposits of precious metals.

“These are not minor mineral holdings,” said Bob McFarlin, vice president for government and public affairs for Twin Metals, a partner in the planned project, which released the results of the new geological analysis. “The state is sitting on an absolute economic juggernaut for generations to come.”
