Location: This prospect is at an elevation of about 1,300 feet on the eastern flank of a north-trending ridge; it is about 2.0 miles southwest of Discovery Camp on Otter Creek, about 0.4 mile northeast of hill 1565, and near the center of section 15, T. 27 N., R. 47 W., of the Seward Meridian. The location is accurate.
Geology: This prospect consists of an iron-oxide-stained quartz vein in hornfels derived from the Upper Cretaceous, Kuskokwim Group (Bundtzen and others, 1992; Miller, Bundtzen and Gray, 2004). The vein was explored with a small drift which has since caved. Float on the surface indicated that the quartz vein is at least 12 inches thick; no sulfides were recognized. Some of the quartz contains visible gold. One grab sample of rubble of the quartz vein contained 11.0 parts per million (ppm) gold, 7.0 ppm silver, 340 ppm arsenic, 50 ppm tungsten, and 140 parts per billion (ppb) mercury (McGimsey and others, 1988; Bundtzen and others, 1992).
Workings: A drift, now caved, and small pit explored the prospect. About 20 tons of mineralized rock occur on the dump. The prospect was sampled by the US. Geological Survey and the Alaska Division of Geological and Geophysical Surveys (McGimsey and others, 1988; Bundtzen and others, 1992).
Alteration: Iron oxide staining.
Production: Probably none.

Commodities (Major) - Ag, Au; (Minor) - As, Hg, W
Development Status: Undetermined.
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
