The prospect was discovered prior to 1912 by Peter Steil and was one of the first adits driven in the Fairbanks district (Times Publishing Company, 1912).
Location: Cobb (1972, MF-413), loc. 37; SW1/4NW1/4 sec. 25, T. 3 N., R. 1 E., of the Fairbanks Meridian. This prospect is at the head of Cleary Creek, at an elevation of 1,475 feet.
Geology: Some stibnite and less pyrite occur in narrow quartz veins that branch through the metabasaltic country rock (Smith, 1913; B 525). By 1912, the adit was 400 feet long and had working drifts driven along the mineralized shear zones. Smith (1913, B 525) indicated the tunnel was caved in 1912 and the property had not reached the production stage, but that a road had been built from the tunnel to the main road to the north. The Steil prospect was examined as a possible source of antimony in 1942 but no additional exploration was conducted due to lack of indication of significant tonnage (Killeen and Mertie, 1951).
Workings: By 1912, an adit was 400 feet long and had working drifts along the mineralized shear zones. But, Smith (1913, B 525) indicated the tunnel was caved in 1912 and the property had not reached the production stage, but that a road had been built from the tunnel to the main road to the north.
