Location: This occurrence is on the north end of Granite Mountain at an elevation of about 1,800 feet. It is about 0.8 mile north of hill 2555 and about 0.6 mile east-southeast of the center of section 9, T. 26 N., R. 40 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence is at the north end of Granite Mountain about 0.6 mile north of the hornfels aureole of the Granite Mountain pluton. The rocks in the area are sandstone and shale of the Upper Cretaceous, Kuskokwim Group (Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). This occurrence is based on a grab sample of what was originally considered to be barren Kuskokwim Group sedimentary rocks. The grab sample contained 500 parts per billion (ppb) silver, 200 parts per million (ppm) lead, 10.0 ppm bismuth, 100 ppm arsenic, and 12 ppm antimony (McGimsey and others, 1988).
Workings: Samples were collected by the U.S. Geological Survey and Alaska Division of Geological and Geophysical Surveys in the 1980s (McGimsey and others, 1988).
