Location: This occurrence is near the top of peak 3162 near the center of the Buckstock Mountains. The occurrence is about 0.2 mile east-southeast of the center of section 17, T. 14 N., R. 51 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence consists of pyrite-rich hornfels derived from the Upper Cretaceous, Kuskokwim Group or Mesozoic Gemuk Group (Cady and others, 1955; M.L. Miller, unpublished field data,1999). The protolith of the fractured hornfels is a medium grained sandstone. The rocks strike N45E and dip 42SE. One grab sample contained up to 21 parts per billion (ppb) gold, 1,750 parts per million (ppm) zinc, 24 ppm molybdenum, and 4.87 ppm cadmium (M.L. Miller, unpublished analytical data, 1999).
Workings: The U.S. Geological Survey investigated the site in 1999.
Age: Unknown. Miller and others (2002) report a U-Pb age of 59.2 Ma from the nearby Buckstock pluton.
Alteration: Sulfides have altered to iron oxides.
Commodities (Major) - Zn; (Minor) - Au, Cd, Mo
Development Status: None
Deposit Model: Polymetallic replacement deposit? (Cox and Singer, 1986; model 19a).
