The Unnamed 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.

Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Chalcopyrite is present in quartz veins in mafic volcanic rocks.??These observations where likely made in rocks mapped as Precambrian volcaniclastic rocks of Redwacke Creek (Reiser and others, 1980). Potassium-argon dating of these rocks indicates Early Jurassic to Late Triassic ages which are not consistent with mapped field relations (Reiser and others, 1980).??Marker beds used in detailed mapping along the U.S.-Canada border consist of volcanicastic rocks that are Ordovician or Cambrian in age and likely stratigraphically equivalent to the Whale Mountain volcanics that contain a Late Cambrian fauna in their basal part (Kelley and others, 1992). Although the age of the volcaniclastic rocks of Redwacke Creek is uncertain and presumed to be Precambrian by Reiser and others (1980), work by Lane and others (1995) and Kelley and others (1992) raises the possibility that the volcaniclastic rocks that have reported to be mineralized are Cambrian to Ordovician in age: if so, the mineralization in them is not akin to mineralization in Precambrain volcanics in the Sadlerochit and Shublik Mountains.
