The Silver Star 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 (Production): Production Notes = Probably none
Comment (Reference): Primary Reference = Buddington, 1923
Comment (Workings): Workings / Exploration = Prospect was staked before 1905 and had small amount of exploration prior to 1921. Apparently dormant since; there is no record of recent claim activity and no obvious sign of recent surface activity.
Comment (Deposit): Model Name = Gold-quartz vein (?) (Cox and Singer, 1986; model 36a)
Comment (Geology): Geologic Description = As described by Wright and Wright, (1905, p. 60) and Buddington (1923, p. 69), the deposit consists of thin quartz-calcite veins containing chalcopyrite, pyrite, and magnetite. The veins cut pyritic black schist that form bands in gneissoid diorite, slate, and greenstone that have been intruded by diorite and diabase dikes. Samples of the veins continued up to 0.4 ounces of gold per ton and 2 ounces of silver per ton.? As more recently mapping by Brew (1997 [OF 97-156-L]), the rocks in the vicinity consist of Mesozoic semischist and phyllite near a contact with Cretaceous phyllite.
Comment (Exploration): Status = Inactive
