Duluth Metals, a company that’s been pushing to build a copper-nickel mine in northeast Minnesota, said Monday it is selling its operations to Chilean mining giant Antofagasta PLC for about $85 million.
Antofagasta and Duluth have been partners in Twin Metals Minnesota, which wants to build an underground mine near Ely, Minnesota.
The region may hold what could be the world’s largest untapped source of copper and other metals valued at perhaps $100 billion.
