PolyMet remains determined to build Minnesota mine

TSX- and NYSE American-listed Polymet remains “determined and confident” that it would advance its copper/nickel mine on the Iron Range, Minnesota, and has this week turned to the Supreme Court to view a lower court ruling on the company’s air permit.

The company is seeking to overturn a state Court of Appeals ruling on March 23 that remanded the air permit to the Minnesota Pollution Control Agency (MPCA). PolyMet is asking the Supreme Court to clarify when a court of appeals can require an agency to make additional findings and whether it can presume without evidence that an agency will not enforce its permits.
