The mineralization is similar to that at the Bismarck Creek prospect (ID130).
Location: This occurrence is on a broad northeast-trending ridge east of the head of Granite Creek on the divide that separates it from the East Fork of the George River. The occurrence is at an elevation of about 1,250 feet, about 0.5 mile northwest of hill 1440, and about 0.5 mile southeast of the center of section 32, T. 27 N., R. 41 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence consists of quartz-axinite veins and veinlets in hornfels derived from the Upper Cretaceous, Kuskokwim Group (Miller and Bundtzen, 1994; Bundtzen and Miller, 1997; Miller, Bundtzen, and Gray, 2005). The size and extent of the occurrence is uncertain. Grab samples of mineralization contain up to 1,000 parts per million (ppm) tin, 5.0 ppm silver, 400 ppm zinc, 2.2 ppm cadmium, and 130 ppm arsenic (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).
Alteration: Development of axinite-quartz greisen.
Commodities (Major) - Sn; (Minor) - Ag, As, Cd, Zn
Development Status: None
Deposit Model: Sn-polymetallic vein or Polymetallic vein (Cox and Singer, 1986; models 20b and
