Köppen climate type:
Location: This prospect is about 1.7 mile north-northeast of Camelback Mountain on a broad summit of a northeast-trending ridge The occurrence is at an elevation of about 2,100 feet, about 0.5 mile north-northwest of the center of section 34, T. 29 N., R. 43 W., of the Seward Meridian. The location is accurate.
Geology: This prospect consists of a zone of quartz-sulfide veins with gradational boundaries in hornfels. The occurrence is adjacent to a small monzonite body that intrudes both the Upper Cretaceous, Kuskokwim Group and andesitic flows of the Iditarod volcanics (Bundtzen, Laird, and Lockwood, 1988; Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). The size of the deposit is unknown. One grab sample of chips from a quartz-sulfide vein contained 12.0 parts per million (ppm) silver, 15.00 percent iron, 710 ppm arsenic, 600 ppm zinc, 500 ppm lead, 70 ppm antimony, 4,200 parts per billion (ppb) mercury, 35 ppm cadmium, and 300 ppm nickel (McGimsey and others, 1988).
Workings: The area was sampled by the U.S. Geological Survey in the 1980s (McGimsey and others, 1988).
Age: Unknown; the Camelback Mountain intrusion about a mile to the south is 73.2 Ma (Bundtzen, Laird, and Lockwood, 1988).
Alteration: Silicification.
Commodities (Major) - Ag, As; (Minor) - Cd, Ni, Pb, Sb, Zn
Development Status: None
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
