|Location and accuracy||Cobb (1972, MF-413), loc. 53; NW1/4 sec. 17, T. 3 N., R. 3 E., of the Fairbanks Meridian. The Eureka mine is on the ridge between Ginger and Walnut Creeks at an elevation of 2,000 feet. The location is marked by a prospect pit 1.5 miles north of Alder Creek Camp. Accuracy is within 1,000 feet.|
Geologic descriptionThis prospect was discovered in 1910 (Times Publishing Company, 1912). By 1911, a 50-foot-deep shaft had been sunk and an unspecified amount of gold ore had been custom milled at the Chena mill in Fairbanks (Brooks, 1912). The width of ore in the Eureka shaft was three feet. The prospect was inactive in 1912 (Smith, 1913; B 525). In 1969, Pilkington and others (1969) collected two samples of shear-zone quartz from the prospect. These samples contained 2.48 and 150 ppm gold (0.072 and 4.38 ounces of gold per ton, respectively).
