The Empire is a silver and 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 = Wilson and others, 1988
Comment (Workings): Workings / Exploration = A 150-foot, south-trending adit is present on the prospect. In 1983 UNC Teton Exploration Drilling Company drilled three core holes for a total of 4,737 feet, conducted VLF and EM surveys, and trenched the prospect.
Comment (Geology): Geologic Description = The Empire prospect is described as vuggy quartz veins, less than 0.5 inch wide, cutting iron-oxide-stained, silicified andesite (Wilson and others, 1988). The andesite is part of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). By analogy with other deposits in the area, the veins presumably contain small amounts of gold or silver.
Comment (Deposit): Model Name = Epithermal gold veins
Comment (Geology): Age = Eocene or younger.
Comment (Exploration): Status = Inactive
