There are more than 4 billion tons of copper+nickel+PGM
resources within many deposits along ~40 miles of the
edge of the Duluth Complex near Babbitt, MN. This
graphic shows the locations of the deposits, the state
mineral leases held by six companies and notes where
resource estimates [NI 43-101 compliant] were completed.
Polymet is the first company to propose a mine in this
district, and the environmental review process is in
progress.
