Environmental advocates are calling on Gov. Mark Dayton to require stronger environmental protections for a proposed copper-nickel mine in northeastern Minnesota.
A major partner has given up the right to take a bigger stake in a proposed copper-nickel mine near Ely in northeastern Minnesota. Chilean-based mining company Antofagasta PLC said Thursday it has terminated its option to buy another 25 percent of Twin Metals Minnesota. The announcement says Toronto-based Duluth Metals Ltd. is now assuming control of the joint venture.
Opponents of the proposed PolyMet copper-nickel mine in northeastern Minnesota charged Thursday new data show that the state’s new draft environmental review for the project underestimates how much contaminated water could flow from the mine, raising serious questions about the long-term costs of treating it.
The possibility of more precious metal mining proposals in northern Minnesota took another step forward on Friday after the state’s executive council approved 31 leases of state and private lands to three mining companies seeking exploration.
Environmental groups are launching a campaign ahead of the summer vacation season against plans for copper, nickel and precious metals mining in northeastern Minnesota.
