Location: This occurrence is reported to be about 1 mile south of the upper Taylor Creek airstrip (T.K. Bundtzen, personal commun., 1992). For this record, the map site is at an elevation of 1,400 feet in the NE1/4 of section 23, T 9 N, R 46 W, of the Seward Meridian. It is very approximately located, perhaps within a mile.
Geology: T. K. Bundzten (personal commun., 1992) reports that disseminated arsenopyrite, cinnabar, pyrite, and minor gold are in hypabyssal rhyolite about 1 mile south of the Taylor Creek airstrip. Sparse sulfides are also in quartz-tourmaline veinlets that cut the rhyolite. Cady and others (1955, p. 71, plate 1) noted east-west-trending rhyolite dikes or sills on the ridges just west of lower Forks Creek, about about 2.5 miles east-northeast of this occurrence. The felsic hypabyssal rocks intrude mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group.
Workings: Some surface examination and sampling has occurred but the nature of any additional work is not known.
Age: Late Cretaceous or Early Tertiary, the age of felsic plutons in southwest Alaska that intrude the mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group.
Alteration: Quartz-tourmaline veining is present.

Commodities (Major) - Au; (Minor) - Ag, Hg
Development Status: None
Deposit Model: Sulfide-bearing veins in or near felsic hypabyssal intrusive rocks
