The Montana Department of Environmental Quality has levied a $516,567 fine for alleged illegal mining activity at the former Zortman-Landusky Mining District, which is in the midst of long-term reclamation efforts to mitigate acid mine drainage. The penalty is accompanied by an order directing property owner Luke Ployhar and Owen Voigt, a mining consultant employed by Ployhar, to stop all mining exploration activities until appropriate licenses have been obtained, complete with a bond to cover the costs of future reclamation.
