Location: The Cheyenne prospect is located about 1400 feet northwest of Cleary Summit along the Steese Highway, on the south side of the road; NE1/4NE1/4, sec. 36, T. 3 N., R. 1 E., of the Fairbanks Meridian.
Geology: By October of 1912, the prospect was known as the Vergil prospect and an 11 foot shaft had been sunk on base metal bearing mineralization which averaged $6.50 per ton in gold (0.3 ounces of gold per ton) and $4.50 per ton in silver (9 ounces of silver per ton). Smith (1913, B 525) was unable to determine the strike and dip of the prospect due to frost action on surface exposures. By 1916, the shaft was 14 feet deep with a short drift at the bottom on a 8-inch-wide, N 55 E, 15 SE shear zone. Mineralization consisted of stibnite with gold and silver credits, arsenopyrite and silver-bearing tetrahedrite. The shear zone was hosted in an iron oxide stained schist cut by numerous quartz stringers (Mertie, 1918). The Cheyenne prospect was examined as a possible source of antimony in 1942 but no additional exploration was conducted due to insufficient tonnage (Killeen and Mertie, 1951).
Workings: By 1916, the shaft was 14 feet deep with a short drift at the bottom (Mertie, 1918). There has apparently been little work since.
