PolyMet copper-nickel mine

Court will hear appeal of a ruling that canceled three permits.

Gov. Mark Dayton says he's moved from being "genuinely undecided'' on the proposed PolyMet copper-nickel mine to being a genuine supporter of the project.

Groups for and against the proposed PolyMet copper-nickel mine are working to turn out their supporters for a public meeting on the project on Tuesday night in Aurora.
