The Saturn is a zinc 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 (Deposit): Model Name = Low temperature lead-zinc skarn (Cox and Singer, 1986; model 18c).
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Unknown; may be related to dated Tertiary intrusions of area (Solie and others, 1991).
Comment (Reference): Primary Reference = Brewer and others, 1992
Comment (Workings): Workings / Exploration = The Saturn prospect was discovered by the Anaconda Minerals Company in 1980 or 1981 (Brewer and others, 1992). Results of limited grab samples collected by North Pacific Mining Company show values of up to 0.3 percent copper, 20.9 percent zinc, and 9.3 grams/tonne silver (Brewer and others, 1992).
Comment (Geology): Geologic Description = The Saturn Prospect consists of discontinuous layers of massive to semi-massive sphalerite and pyrrhotite within a 300 meter by 10 meter wide skarn zone in limestone of the Barren Ridge Limestone, a unit of the Dillinger subterrane (Bundtzen Harris, and Gilbert, 1997). The limestone is adjacent to highly altered, Late Cretaceous, Veleska Lake Volcanic field, which has in turn been intruded by a weakly mineralized granite porphyry pluton about 300 meters from the prospect (Bundtzen, Kline, and Clough, 1982). . Results of limited grab samples conducted by North Pacific Mining Company show values ranging up to 0.3 percent copper, 20.9 percent zinc, and 9.3 grams/tonne silver (Brewer and others, 1992).
