Hudson

The Hudson is a gold mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Reference): Primary Reference = Smith, 1913 (B 525)

Comment (Exploration): Status = Inactive

Comment (Deposit): Model Name = Schist-hosted gold-quartz vein

Comment (Production): Production Notes = There is no record of the amount of production, but there was some.

Comment (Geology): Geologic Description = 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.

Comment (Workings): Workings / Exploration = 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.
