Barker/Hughesville Mining District

Pioneer completed a comprehensive cost estimate report for the remedial actions at the Barker/Hughesville Mining District. This cost estimate was provided to the Montana Department of Environmental Quality for the reclamation of 45 individual mine sites and the water treatment of 250 gallons per minute (gpm) of mining impacted water located within the mining district. This cost estimate justified the reclamation and capital costs and provided the basis of expert witness for mediation for the Montana Department of Environmental Quality as part of the ASARCO bankruptcy negotiations.
