The Center Star is a gold and copper 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 (Workings): Workings / Exploration = Minor open cut workings.
Comment (Reference): Primary Reference = Cobb, 1978 (OFR 78-1062)
Comment (Geology): Geologic Description = Thick Quaternary glacial deposits and Upper Tertiary sedimentary strata cover most of the older bedrock in this area. Regionally, the main geologic feature is the northeast-trending Chulitna fault, which separates a sequence of Upper Jurassic to Upper Triassic(?) crystal tuff, argillite, chert, graywacke, and limestone on the north, from Upper Devonian to Lower Triassic volcanogenic and sedimentary rocks on the south. Faulting and shearing of the rocks has occurred, along with intrusions of Late Cretaceous dikes and stocks. As reported by Capps (1919), the Center Star prospect consists of arsenopyrite, pyrite and chalcopyrite disseminated in bluish dike rock.
Comment (Deposit): Other Comments = This site may overlap the Liberty prospect (HE028).
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Possibly Late Cretaceous or younger.
