Location: This occurrence is at the head of Boss Creek, a north-flowing tributary of the Holokuk River. The occurrence is at an elevation of about 1,400 feet in the SW1/4 sec. 36, T. 12 N., R. 50 W., of the Seward Meridian. The location is approximate.
Geology: This occurrence consists of silicified graywacke of either the Upper Cretaceous, Kuskokwim Group or the Mesozoic Gemuk Group (Cady and others, 1955). The silicified graywacke is cut by quartz veins with disseminated pyrite (Gray, Motooka, and Theodorakos, 1997). No other information is available. One grab sample of silicified graywacke contained 1,000 parts per million (ppm) arsenic, 50 parts per billion (ppb) gold, and 6.1 ppm antimony (Gray, Motooka, and Theodorakos, 1997).
Workings: The U.S. Geological Survey sampled the occurrence in 1995 (Gray, Motooka, and Theodorakos, 1997).
Alteration: Silicification of graywacke.
