|Location and accuracy||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).|
Geologic descriptionThe 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.
