Location: This occurrence is about 0.4 mile west of the top of Camelback Mountain at an elevation of about 2,000 feet. It is about 0.4 mile southwest of the center of section 1, T. 28 N., R. 44 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence is a vein of semi-massive pyrrhotite in hornfels adjacent to the Camelback Mountain intrusion. This olivine bearing monzonite intrusion has been dated at 73.2 Ma (Bundtzen and others, 1988; Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). Traces of chalcopyrite occur in the pyrrhotite. The orientation or length of the vein is uncertain. One grab sample of the pyrrhotite vein contained 2,600 parts per billion (ppb) silver, 891 parts per million (ppm) copper, 1.68 percent manganese, 304 ppm zinc, and 28.00 percent iron (Bundtzen, Laird, and Lockwood, 1988).
Workings: Surface samples were collected by the Alaska Division of Geological and Geophysical Surveys in 1983 (Bundtzen, Laird, and Lockwood, 1988).
Age: Undated; the nearby Camelback Mountain intrusion is 73.2 Ma (Bundtzen and others, 1988).
Commodities (Major) - Ag, Cu; (Minor) - Fe, Mn, Zn
Development Status: None
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
