Location: This occurrence is on a steep north-facing slope about 500 feet east of hill 3670 in the north-central Beaver Mountains, The occurrence is at an elevation of about 3,000 feet in the SE1/4 SE1/4 section 30, T. 33 N., R. 40 W., of the Seward Meridian. The location is approximate.
Geology: This occurrence consists of a 10-foot-zone of vein-type mineralization in a cupola of the Upper Cretaceous, Beaver Mountains stock (Szumigala, 1993; Bundtzen and Laird, 1982). The zone contains veinlets of tourmaline, quartz, and minor chalcopyrite. No size or orientation information is available. One chip sample contained 43 parts per billion (ppb) gold, 60.0 parts per million (ppm) silver, 1.03 percent copper, 108 ppm lead, 247 ppm zinc, and 94.5 ppm arsenic (Szumigala, 1993).
Workings: Surface sampling was conducted by Battle Mountain Mining Company in 1990. Samples were collected and analyzed by the Alaska Division of Geological and Geophysical Surveys in 1992 (Szumigala, 1993).
Age: May be related to the Beaver Mountains pluton which has been dated at 70.1 Ma. (Bundtzen and Laird, 1982).
Alteration: None noted.
Commodities (Major) - Ag, Cu; (Minor) - As, Au, Pb, Zn
Development Status: No
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
