Location: Cobb (1972, MF-413), loc. 49; SW1/4NW1/4 sec. 23, T. 3 N., R. 2 S., of the Fairbanks Meridian. The Governor prospect is on the ridge between Too Much Gold Creek and Moose Creeks, at an elevation of 1,850 feet, approximately 1/2 mile north of the junction of Too Much Gold Creek and Fairbanks Creek. Accuracy is within 1,000 feet.
Geology: The Governor prospect was originally staked by Aaron and Matt Cook as the Governor and Mayor claims on August 15, 1910 (Times Publishing Company, 1912). Three and one-half tons of ore from the Governor mine were custom milled in December 1910 and averaged $73 gold per ton (3.5 ounces of gold per ton) (Times Publishing Company, 1912). By 1911, a 30-foot-deep shaft had been sunk on a one-foot-wide shear zone (Brooks, 1912). By 1912, the shaft had been deepened to 70 feet and 40 feet of drift had been driven from the bottom of the shaft (Times Publishing Company, 1912). The workings were driven on a vertically-dipping, N 80 W striking, shear zone which varied from 8 to 30 inches wide (Smith, 1913; B 525; Times Publishing Company, 1912). Some of the ore was derived from a fine grained granitic rock which carried $10 to $15 gold per ton (0.48 to 0.72 ounces of gold per ton). This rock contains iron stained vugs where sulfide minerals have been oxidized. The granitic rock is highly sheared and slickensided. In 1912, the possible extension of the Governor shear was being prospected approximately 900 feet east of the Governor shaft (Smith, 1913; B 525). In 1969, International Minerals and Chemicals Company conducted soil sampling and excavated an 805 foot trench across the Governor shear zone to follow-up soil geochemical anomalies (Pilkington, 1970). This trench was oriented north-south and although shear zones exposed in the trench coincided with soil geochemistry anomalies, no significant gold was found samples.
Workings: By 1911, a 30 foot deep shaft had been sunk on a one foot wide shear zone (Brooks, 1912). By 1912 the shaft had been deepened to 70 feet and 40 feet of drift had been driven from the bottom of the shaft (Times Publishing Company, 1912). The workings were driven on a vertically-dipping, N 80 W striking, shear zone which varies from 8 to 30 inches wide (Smith, 1913; B 525; Times Publishing Company, 1912). In 1912, the possible extension of the Governor shear was being prospected approximately 900 feet east of the Governor shaft (Smith, 1913; B 525). In 1969, International Minerals and Chemicals Company conducted soil sampling and excavated an 805 foot north-south trench across the Governor shear zone to follow-up soil geochemical anomalies (Pilkington, 1970).
Production: Three and one-half tons of ore from the Governor prospect were custom milled in December 1910 and averaged $73 per ton in gold (3.5 ounces of gold per ton, Times Publishing Company, 1912).
