Agency: NF Region District: R1 Ranger District: WISE RIVER Forest Service Tract: Watershed Code: 10020004 Forest or Resource Area: BEAVERHEAD Owner: N Impact: Report: White Cap Mine BE000773 Quote from Geach, R.D., MBMG Bulletin 85, p. 151..... "The White Cap mine is in the SW1/4 sec. 12, T. 1 N., R 13 W., about 3/4 mile due west of the Calvert open-pit tungsten mine, from which it can be reached by mountain road. The unpatented claim was located in 1956 by George Henderson of Anaconda, Montana. The country rock is buff, sugary dolomite, which is believed to be part of the Hasmark Formation. A prospect pit, 8 feet deep, has been sunk on a 4-foot mineralized zone in the dolomite (Fig.86). The zone has the characteristic of a vein and strikes N. 30 W. and dips 76 NE. The 2 ½-foot hanging wall part of the zone is mineralized by white to gray quartz, blebs of galena, and anglesite, and is copper stained. A chip sample across it assayed 0.08 percent copper, 0.25 percent lead, 0.014 percent WO3, 0.002 ounce of gold, and 0.06 ounce of silver per ton. The footwall of the zone consists of a boxwork of silica ribs in dolomite. A chip sample of this material assayed 0.05 percent copper, 0.20 percent lead, 0.014 percent WO3, 0.005 ounce gold, and 0.60 ounce silver per ton. Bulldozer trenches have been dug around the discovery pit but no ore was discerned in any of them. Total recorded production from the property is 10 tons of ore produced in 1960; it yielded 62 ounces of silver." This study examined the general area via a fairly new logging road leading up from the Calvert mine, that leads to at least four prospect pits in the area. None were positively identified as the White Cap, but most had similar characteristics. Two are merely trenches, dry and shallow; two were probably dug over existing springs and are providing water at a rate of approximately 2 to 3 gpm. They were considered to be of no or minimal impact to the National Forest land. Truckle (1988) has no Hasmark Formation in this general area but does have Permian Phosphoria and Pennsylvanian Quadrant formations. |
