Location: Cobb (1972, MF-413), loc. 49; SW1/4 sec. 23, T. 3 N., R. 2 E., of the Fairbanks Meridian. This mine is just north of the junction of Too Much Gold Creek and Fairbanks Creek, adjacent to the road, east of the creek. Accuracy is within 1,500 feet.
Geology: By 1912, an 18-foot-deep pit had been excavated and exposed a highly brecciated quartz-rich, shear zone cemented by pyrite, galena and stibnite (Smith, 1913; B 525). This brecciation post-dates an auriferous quartz stockwork zone from which a small amount of material had been sacked for shipment to a nearby custom mill. Several white porphyritic granite dikes up to 70 feet wide were exposed in the immediate vicinity of this exposure. These dikes are roughly parallel to the gold-quartz shear zone which strikes N 70-80 W and dips vertically. This granite was not thought to be highly mineralized however, no analytical data are available (Smith, 1913; B 525). In late 1915, about 30 tons of ore from the prospect was custom milled and some development work was carried out (Stewart, 1915; Smith, 1917, BMB 142). The workings on the Whitehorse prospect were caved by 1931 and the site was still inactive in 1942 (Hill, 1933; Killeen and Mertie, 1951). In 1969, International Minerals and Chemicals Company conducted soil sampling at the site and excavated a 700 foot dozer trench across the Whitehorse shear zone to follow-up soil geochemical anomalies (Pilkington, 1970). This trench was oriented north-south and the shear zones exposed in the trench coincided with soil geochemistry. Sporadic gold was encountered in this trench; one, five-foot sample contained 1.2 ppm gold (0.035 ounces of gold per ton). The host for this mineralization is unknown.
Workings: In late 1915 about 30 tons of ore from the prospect was custom milled and some development work carried out (Stewart, 1915, Smith 1917, BMB 142). The workings on the Whitehorse prospect were caved by 1931 and the site was still inactive in 1942 (Hill, 1933; Killeen and Mertie, 1951). In 1969, International Minerals and Chemicals Company conducted soil sampling and excavated a 700 foot dozer trench across the Whitehorse shear zone to follow-up soil geochemical anomalies (Pilkington, 1970).
Production: In late 1915, about 30 tons of ore from the prospect was sent to a custom mill nearby (Smith, 1917; BMB 142).
