Black Pine Mine



Please click on the tabs below for more information on the Black Pine Mine cleanup.

The Black Pine Mine (BPM/Site) is an inactive silver mine located 10 miles northwest of Philipsburg in Granite County. The BPM complex includes 1,056 acres of patented mining claims and 150 unpatented lode claims. It is surrounded by lands administered by the US Forest Service. Approximately 400,000 CY of metals-impacted wastes are estimated to be present at, and down gradient of the Site. The impacted wastes include waste rock, tailings, and metals impacted soils and sediments.

The BPM is one of five sites in Montana that was owned and operated by ASARCO, until their bankruptcy filing in August 2005. In December 2009, $17.3 million was allocated to the BPM for environmental actions at the Site. DEQ was appointed as the lead agency for the reclamation. These funds are being managed by the Montana Environmental Trust Group, LLC (METG), Trustee for the Montana Environmental Custodial Trust.

DEQ performed a site characterization to investigate the nature and extent of contamination associated with mining and milling waste at the Site. Based on the results of the site characterization, reclamation alternatives are being evaluated to address human health and ecological risk.
