Location: 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.
Geology: This 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).
Workings: Surface samples were collected by Battle Mountain Mining Company in 1990 (Szumigala, 1993).
Age: Unknown; the nearby Beaver Mountains stock, which probably underlies the area is 70.9 Ma (Miller and Bundtzen, 1994).
Alteration: Development of veins of quartz-tourmaline greisen.

Commodities (Major) - Ag, Au; (Minor) - As, Cu, Pb, Zn
Development Status: None
Deposit Model: Polymetallic vein? (Cox and Singer, 1986; model 22c).
