Report: Copper Hill LC001489 This location of this prospect is in the same general place as the Grunter and Bluebell claims as plotted from the MILS database. It may also be known as the Big 4 Mining Company properties and consisted of 4 unpatented mining claims. The mineralization occurs as veins and as secondary copper in Precambrian Belt quartzite (Spokane Formation). Workings include several old prospect pits downhill from a talus where several bulldozer trenches were cut. Minerals present include secondary copper minerals, iron oxides, manganese oxides and quartz. An eight ton bulk sample taken in 1960 averaged 1.37% Cu (U.S.B.M. mineral property file 21.96). A grab sample (PBGBB-1) from taken vertically on the talus ran <0.0005 opt Au, 1.84 opt Ag, 2.72% Cu, 0.01% Pb, and 0.002% Zn. This prospect is located on Helena National Forest land. A 4x4 road/trail leads up from Canyon Creek or access may be gained by foot after driving up the road off the switchback at the base of Flesher Pass. No discharges or hazardous physical aspects (besides being a steep talus) are associated with this site.
