The prospect is in Denali National Park.
Location: This prospect is at an elevation of about 3850 feet on the crest of the ridge that separates the head of Rainy Creek from the West Fork of Glen Creek. It is in the NW1/4 SE /4 section 2, T. 16 S., R. 17 W., Fairbanks Meridian. The location is accurate within 500 feet.
Geology: The country rock in the area of this prospect is primarily metafelsite schist of the lower Paleozoic Spruce Creek sequence; float of Tertiary basalt occurs nearby (Bundtzen, 1981; Thornsberry, McKee, and Salisbury, 1984, fig. K-2). The deposit consists of anastomosing, pyrite- and stibnite-bearing quartz-calcite-tourmaline veins. The veins are in a zone several feet wide that can be traced easterly in a series of pits and an adit, all sloughed or caved. A grab sample assayed 4.55 percent lead, 0.064 ounce of gold per ton, 97.2 ounces of silver per ton, and 1.8 percent antimony. Copper, zinc, and arsenic contents are each in the 0.X percent range. The lead assay indicates the presence either of galena or another lead-bearing mineral.
Workings: The deposit was explored by several pits and a short adit, since caved.
Age: The deposit is assumed to be Eocene (see record MM091).
Commodities (Major) - Ag; (Minor) - Au, Pb, Sb
Development Status: Undetermined.
Deposit Model: Polymetallic vein (Cox and Singer, 1986; model 22c).
