Location: Frost (1990) and Frost and others (1992; 1993), reported mineralization approximately at this locality. It is about 1 mile east of Gold Creek, 4 miles north-northeast of Gold Lake, and 3 miles southwest of Kisaralik Lake. For this record, the map site is at an elevation of about 2,100 feet on the northwest end of a ridge, in the NW1/4 of section 12, T 2 N, R 59 W, of the Seward Meridian.
Geology: Oxidized pyrite-bearing rhyolite dikes and sulfide-bearing quartz veins cut Jurassic volcaniclastic rocks at this locality (Box and others, 1993). Anomalous values of Ag, As, Au, Cu, Hg, Mo, Pb, Sb, and W are found in quartz veins, altered dikes, and hydrothermal breccia (Frost, 1990; Frost and others, 1993). The maximum gold value is 2 ppm and the maximum silver value is 7 ppm. The dikes are variably replaced by sericite, illite, and quartz. Galena is the only sulfide mineral identified in the quartz veins.
Workings: Reconnaissance surface sampling and observation is all that has been reported for this locality.
Age: Late Cretaceous or Early Tertiary (?); postdates Jurassic host rocks and is probably related to the Upper Cretaceous/Lower Tertiary suite of intermediate to felsic intrusive rocks in the region (Box and others, 1993).
Alteration: Silicification, argillization, and oxidation.
Commodities (Major) - Ag, Au; (Minor) - Pb, Sb, W
Development Status: None
Deposit Model: Polymetallic veins (Cox and Singer, 1986; model 22c).
