Location: The map site of this approximately located occurrence is at an elevation of about 3,200 feet, on the crest of the northwest-trending ridge about 1/2 mile north of Kisarilik Lake. The site is at the midpoint of the north boundary of sec. 22, T 3 N, R 57 W, of the Seward Meridian. It is locality 14 of Frost (1990, fig. 1). The location is accurate within about 1/2 mile.
Geology: Pyrite-bearing rhyolite dikes and sulfide-bearing quartz veins cut Jurassic volcanic and sedimentary rocks on the ridges north of Kisarilik Lake (Frost, 1990; Box and others, 1993). Rock samples from this large, red-weathering area, contain up to 0.41 ppm Au, 1.5 ppm Ag, 7,000 ppm As, and 100 ppm Sb (Frost, 1990; Frost and others, 1992).
Workings: Reconnaissance surface observation and geochemical sampling has occurred at this site.
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: Quartz veining, oxidation.

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