DNR weighs new review for NorthMet copper-nickel mine
The Minnesota Department of Natural Resources is weighing whether proposed changes to the NorthMet copper-nickel mine require a supplemental environmental impact statement, and it plans to decide on next steps in roughly one month.[1]
NewRange Copper Nickel proposed increasing ore production from 32,000 to 40,000 tons per day and shortening the mine life from 20 to 16 years.[1] The redesign would swap rail transport for a covered conveyor and place tailings on adjacent, previously mined iron-ore lands.[1] NewRange has also filed a Clean Water Act Section 404 wetland permit application with the U.S. Army Corps of Engineers.[1]
NewRange Copper Nickel submitted the proposed changes as part of the project's ongoing review of the NorthMet plan.[1] Environmental advocates led by the Minnesota Center for Environmental Advocacy say the project still poses serious acid-drainage risks and that they will scrutinize any claims of reduced impact.[1]
