Location: This occurrence is in the canyon of an unnamed, north-northeast- flowing, tributary of the Buckstock River in the western Buckstock Mountains. The occurrence is at an elevation of about 1,300 feet, about 0.4 mile north-northeast of the center of sec. 35, T. 13 N., R. 53 W., of the Seward Meridian. The location is approximate.
Geology: The rocks in the area consist of sandstone and shale of the Upper Cretaceous, Kuskokwim Group that have been intruded by numerous, felsic and intermediate dikes and sills (Cady and others, 1955; Gray, Motooka, and Theodorakos, 1997). One sample collected here of of graywacke hornfels containing disseminated pyrite, 150 parts per million (ppm) arsenic, and 8.4 ppm bismuth (Gray, Motooka, and Theodorakos, 1997). Several anomalous stream sediment and panned concentrate samples were collected in the vicinity (Gray, Motooka, and Theodorakos, 1997). Stream sediment samples contain up to 10 parts per billion (ppb) gold and 1.3 parts per million (ppm) bismuth. Panned concentrate samples contain up to 1,000 ppm bismuth, 1,000 ppm tungsten, 30 ppm gold, and 10 ppm silver.
Workings: Samples were collected by the U.S. Geological Survey in 1995 (Gray, Motooka, and Theodorakos, 1997).
