Location: Cobb (1972, MF-413), loc. 15; SE1/4SE1/4 sec. 31, T. 3 N., R. 1 E., of the Fairbanks Meridian. The prospect is 1/2 mile north of Dome Camp, at an elevation of about 1,000 feet. Accuracy is within 2,500 feet.
Geology: Material on dumps is graphitic limestone heavily impregnated with disseminated sulfides, mainly pyrite with some chalcopyrite and arsenopyrite (Smith, 1913; B 525, p. 194). Smith (1913, B 525) also reported post-sulfide faulting. Two shafts were sunk on this prospect (Smith, 1913; B 525, p. 180). The western shaft was 147 feet deep, with a short crosscut at the bottom running eastward. The eastern shaft, 200 paces east of the western shaft, was sunk 215 feet. The first 60 feet was sunk through muck and the rest through rock with no intervening gravel. No production has been reported.
Workings: Two shafts were sunk on this prospect (Smith, 1913; B 525, p. 180). The western shaft was 147 feet deep, with a short crosscut at the bottom running eastward. The eastern shaft, 200 paces east of the western shaft, was sunk 215 feet. The first 60 feet was sunk through muck and the rest through rock with no intervening gravel. The two shafts were nearly filled with water in 1912 (Smith, 1913; B 525, p. 180).
