Köppen climate type:
The prospect is in Denali National Park and Preserve.
Location: This prospect is on the south bank of Stampede Creek at an elevation of about 2150 feet (White, 1942). It is in the SW1/4 SW1/4 section 36, T. 13 S, R. 15 W., Fairbanks Meridian. The location is probably accurate within 500 feet. The prospect corresponds to number 110 of Thornsberry, McKee and Salisbury (1984).
Geology: The country rocks in the area of this prospect are calcareous muscovite schist and quartzite of the Birch Creek Schist (Thornsberry, McKee, and Salisbury, 1984, pl. K-4; White, 1942, pl. 49). The deposit consists of stibnite, partly oxidized to stibiconite, in quartz veins. Locally, the stibnite forms massive veins and lenses as much as 5 feet across. Pyrite locally accompanies the stibnite. A grab sample of the stibnite contained 19 percent antimony, but essentially no gold or other valuable metals.
Workings: The prospect was explored by one small cut excavated in 1941 or earlier (White, 1942). Exposures in the area are poor.
Age: The deposit is assumed to be Eocene (see record MM091).
Alteration: Partial oxidatiion of stibnite to stibiconite.
Commodities (Major) - Sb
Development Status: Undetermined.
Deposit Model: Simple Sb deposit (Cox and Singer, 1986; model 27d).
