Location: Cobb (1972, MF-413), loc. 30; SE1/4NE1/4 sec. 2, T. 2 N., R. 1 E., of the Fairbanks Meridian. This mine is west of Skoogy Creek about 3/4 of a mile east southeast of Pedro Dome and about 1/4 mile west of Golden City. Accuracy is within 1,000 feet.
Geology: Gold occurs in a quartz vein in silicified schist; the vein is oriented N 70 E, 35 S (Hill, 1933). The vein varies in width from 6 inches to 22 inches wide (Chapin, 1919; Hill, 1933). Samples assayed $1.04 and $1.24 gold per ton, or 0.05 to 0.06 ounces of gold per ton (Hill, 1933). Two veins, 1/2 to 1 inch wide and 1 to 4 inches wide, contain arsenopyrite and visible gold, they assayed $13.46 and $77.84 per ton (0.65 ounces of gold per ton and 3.77 ounces of gold per ton) (Hill, 1933). A 100 foot adit was driven on the vein with a 65 foot long stope (Chapin, 1919). Production was reported in 1917 and 1918 but the amount is not known (Chapin, 1919; Martin, 1920).
Workings: A 100 foot adit was driven on the vein with a 65 foot long stope (Chapin, 1919).
