Location: The Hudson mine is at an elevation of about 1,500 feet and 0.4 mile north of the mouth of Moose Gulch and 1.5 miles west-northwest of the town of Ester. It is in the SW1/4 sec. 1, T. 1 S., R. 3 W., Fairbanks Meridian.
Geology: Before 1913, most of the mining between Moose Gulch and Ready Bullion Creek, took place at an elevation of about 1,500 feet at the Hudson mine (Smith, 1913 [B 525, p. 203-206]). Smith reported that the rock in the shaft was mineralized; however, there was no well-defined lode. A fault plane was exposed on the east side of the shaft that showed well-marked striations and grooves that indicated multiple directions of movement. The bedrock is chloritic schist with numerous small quartz veins that cut the schist at high angles. In addition to the narrow quartz veins, there are larger masses of barren quartz. In a few places, the bedrock is quartzite that is stained brown with limonite, likely from the decomposition of sparsely disseminated pyrite. The richest ore in the mine occurs in narrow quartz stringers that intersect the country rock in various directions. Free gold occurs in these sulfide-free quartz stringers, with a greater concentration of gold near the walls rather than in the center of the veins. Although most of the gold occurs in these narrow quartz veins, numerous gold particles were panned from a sample of the country rock.
Workings: Before 1913, most of the mining between Moose Gulch and Ready Bullion Creek, took place at an elevation of about 1,500 feet at the Hudson mine (Smith, 1913 [B 525, p. 203-206]). The original shaft was sunk at an elevation of about 1,500 feet but was soon abandoned and a new shaft was sunk a short distance above it. The original shaft was vertical to a depth of 40 feet; the dip of the deposit then flattened, and a 45 -egree incline was sunk to the northwest to a depth of about 94 feet. When visited by Smith in 1912, the lower part of the incline had caved.
Production: There is no record of the amount of production, but there was some.
