The Eureka 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 (Exploration): Status = Inactive
Comment (Workings): Workings / Exploration = Brooks (1912) reported a 50 foot shaft.
Comment (Reference): Primary Reference = Brooks, 1912
Comment (Production): Production Notes = Some ore was milled in 1911 (Brooks, 1912).
Comment (Geology): Geologic Description = This prospect was discovered in 1910 (Times Publishing Company, 1912). By 1911, a 50-foot-deep shaft had been sunk and an unspecified amount of gold ore had been custom milled at the Chena mill in Fairbanks (Brooks, 1912). The width of ore in the Eureka shaft was three feet. The prospect was inactive in 1912 (Smith, 1913; B 525). In 1969, Pilkington and others (1969) collected two samples of shear-zone quartz from the prospect. These samples contained 2.48 and 150 ppm gold (0.072 and 4.38 ounces of gold per ton, respectively).
Comment (Deposit): Model Name = Gold-quartz vein.
