Report: Blackfoot Mine LC007393 Blackfoot Tailings LC008025 Roadside, highly visible tailings and a poorly fenced shaft are the major concerns here. The tailings are not in contact with the Blackfoot River which is on the opposite side of Highway 200. Pioneer Technical Services (1994, 5-127) estimated the tailings volume as 5000 cubic yards, and elevated levels of As, Co, Cu, Hg, Pb, Cd, Cr, Fe, Ni, and Zn. Groundwater also had observed releases of all of the above minerals except Co and MCL's were exceeded for Cu, Cr, Hg, and Ni. Workings consist of numerous open cuts, one nearly totally collapsed adit and one trench/shaft which is poorly fenced. The occurrence is hosted by a north-trending shear zone in a diorite dike intruded into Precambrian Belt argillites and quartzites. Mineralization (also from Pardee and Schrader) includes quartz, siderite (?), iron oxides and pyrite with primarily sericite alteration. McClernan (1983) reiterates Pardee and Schrader. Ownership maps show this as being located primarily on Helena National Forest land
