The Unnamed is a zinc and lead 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 (Geology): Age = Quaternary
Comment (Production): Production Notes = Historically, creek placers in the region have been grouped with the mines and prospects of the Richardson district. From 1905 through 1921, production from the Richardson district was approximately 95,000 ounces of gold and 24,000 ounces of silver (Bundtzen and Reger, 1977). Since 1980, the district has produced approximately 10,000 additional ounces of gold from intermittent mining (Olson and others, 1985). Individual gold production for Gold Creek has not been reported separately.
Comment (Commodity): Ore Material = Quartz
Comment (Workings): Workings / Exploration = Exploration to determine the lode source for the placer gold in the Gold Creek drainage is currently being conducted (R. Van Nieuwenhuyse, oral communication, 1998).
Comment (Reference): Primary Reference = Menzie and Foster, 1979
Comment (Geology): Geologic Description = Menzie and Foster (1979) noted a mineral occurrence situated in the headwaters of Gold Creek, a tributary of the North Fork of the Salcha River. The occurrence is reported to be galena and sphalerite in a secondary silica layer in impure limestone. Weber and others (1978) describe the local bedrock as quartzite, phyllite, slate, and marble. Exploration to determine the lode source for the placer gold in the Gold Creek drainage is currently being conducted (R. Van Nieuwenhuyse, oral communication, 1998).
