Location: This occurrence is at an elevation of about 2,400 feet, about 1.1 mile north of Camelback Mountain. It is about 0.1 mile southeast of the center of section 33, T. 29 N., R. 44 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence is along a faulted contact between monzonite of the Camelback Mountain intrusion and sandstone and shale of the Upper Cretaceous, Kuskokwim Group (Miller and Bundtzen, 1994; Miller, Bundtzen and Gray, 2004). The olivine-biotite monzonite on Camelback Mountain has been dated at 73.2 Ma (Bundtzen, Laird, and Lockwood, 1988). The mineralized zone contains quartz, pyrite, a gray sulfosalt, possibly tennantite, and oxidation minerals after the sulfides. Grab samples contain up to 200 parts per billion (ppb) gold, 2,900 ppb silver, 210 parts per million (ppm) copper, 349 ppm zinc, 127 ppm arsenic, and 3,000 ppb mercury (Bundtzen, Laird, and Lockwood, 1988; McGimsey and others, 1988).
Workings: The occurrence was sampled by Alaska Division of Geological and Geophysical Surveys and the U.S. Geological Survey in the 1980s (Bundtzen, Laird, and Lockwood, 1988; McGimsey and others, 1988).
Age: Unknown; the Camelback Mountain intrusion is 73.2 Ma (Bundtzen, Laird, and Lockwood, 1988).
Alteration: None identified.

Commodities (Major) - Ag, Au; (Minor) - As, Cu, Hg, Zn
Development Status: None
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
