MINNEAPOLIS (AP) — The Biden administration dealt a serious blow Wednesday to the proposed Twin Metals copper-nickel mine in northeastern Minnesota, ordering a study that could lead to a 20-year ban on mining upstream from the Boundary Waters Canoe Area Wilderness.

The U.S. Forest Service filed an application with the Bureau of Land Management for a “mineral withdrawal,” which would begin with a two-year comprehensive study of the likely environmental and other impacts of mining if it were permitted in the watershed that flows into the Boundary Waters.
