The Unnamed (in western Candle Hills) is a 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 = One grab sample contained 233 ppm copper and 0.9 grams/tonne silver (Bundtzen and Laird, 1983).
Comment (Geology): Geologic Description = This occurrence consists of chalcopyrite blebs and disseminations in quartz-epidote veinlets hosted in a porphyritic, subaerial basalt radiometrically dated at 73 Ma (Bundtzen and Miller, 1997). The occurrence is limited to a small 5 meter by 6 meter outcrop surrounded by vegetation and talus. One grab sample contained 233 ppm copper and 0.9 grams/tonne silver (Bundtzen and Laird, 1983).
Comment (Reference): Primary Reference = Bundtzen and Laird, 1983
Comment (Geology): Age = Unknown; probably associated with 69-73Ma Candle volcanic-plutonic complex.
Comment (Deposit): Other Comments = Mineralization may be related to the Au-polymetallic prospect in the valley of Candle Creek (MG003).
Comment (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c).
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Chronological age is for Candle volcanic-plutonic complex.
