Location: The Vermillion prospect is about 0.3 mile west of the mouth of McCally Creek at an elevation about about 450 feet. It is in the NW1/4 sec. 6, T. 19 N., R., 44 W., of the Seward Meridian. The prospect is locality 20 of Miller and others (1989). The location is accurate to within about 100 feet.
Geology: The Vermillion prospect consists of disseminated cinnabar and stibnite in thin quartz veins that intrude a shale-rich section of the Upper Cretaceous, Kuskokwim Group (Cady and others, 1955; Miller and others, 1989). The dimensions and orientation of the deposit are unknown. The Kuskokwim Group strikes N60W and dips 40 SW in the area of the prospect. The Vermillion prospect is geologically and mineralogically similar to the nearby Mercury prospect (SM026). Native mercury has been panned in McCally Creek just downslope from the Vermillion prospect (Sainsbury and MacKevett, 1965).
Workings: The prospect was systematically trenched prior to 1952 (Cady and others, 1955).
Age: Undated; the nearby Fairview prospect (ARDF SM019) has a 40Ar/39Ar age of 72.6 Ma (Gray, Gent, and others, 1997).

Commodities (Major) - Hg, Sb
Development Status: None
Deposit Model: Silica-carbonate mercury (Cox and Singer, 1986; model 27c).
