|Location and accuracy||This occurrence is at an elevation of about 3,200 feet in the southeastern Beaver Mountains. It is about 0.7 mile north-northeast of peak 3410, about 0.9 mile west of peak 2910, and about 0.3 mile east-northeast of the center of section 35, T. 32 N., R. 41 W., of the Seward Meridian.|
Geologic descriptionThis occurrence consists of a stockworks of quartz-tourmaline-chalcopyrite veins in altered lapilli tuff of the Beaver Mountains volcanic field (Bundtzen and Laird, 1982; Miller and Bundtzen, 1988, 1994; Szumigala, 1993). No size or structural information is available. A grab sample of the mineralization collected by Battle Mountain Mining Company contained 1,569 parts per billion (ppb) gold, 194.0 parts per million (ppm) silver, 2,715 ppm copper, 5,449 ppm lead, 304 ppm zinc, and 123 ppm arsenic (Szumigala, 1993).
