The Unnamed (ridge west of Stevens Creek) is a tungsten 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 (Exploration): Status = Inactive
Comment (Geology): Age = Late Cretaceous or Early Tertiary, the age of the Taylor Mountain pluton.
Comment (Reference): Primary Reference = Cady and others, 1955
Comment (Deposit): Model Name = Wolframite in quartz veins
Comment (Geology): Geologic Description = The core of the Taylor Mountains is an Upper Cretaceous or LowerTertiary granite pluton that sharply crosscuts and thermally metamorphoses mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group (Cady and others, 1955, p. 83, 121). Quartz veins are common in the pluton near its border and in the contact-metamorphic rocks. Wolframite was identified in vein quartz float that apparently weathered from the contact-metamorphic zone on the ridge west of Stevens Creek.
