The Little Taylor Mountains is a copper and gold 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 (Geology): Age = Late Cretaceous or Early Tertiary, the age of felsic plutons in southwest Alaska that intrude the mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group.
Comment (Reference): Primary Reference = Cady and others, 1955
Comment (Workings): Workings / Exploration = Some surface examination and sampling has probably occurred, but the nature of any additional work is not known.
Comment (Deposit): Model Name = Gold (?)-bearing altered felsic intrusive rocks
Comment (Geology): Geologic Description = Several felsic dikes or sills cut mid-Cretaceous clastic sedimentary rocks of the Kuskokwim Group in the higher parts of the Little Taylor Mountains (Cady and others, 1955, p. 71, plates 1 and 6). At a locality a little northwest of the summit of the Little Taylor Mountains, the felsic sheets trend northwest, and dip southwest, parallel to the enclosing sedimentary rocks. The felsic intrusions and the enclosing sedimentary rocks are strongly silicified and pyrtitized. 'Traces of copper' were also noted by Cady and others (1955, p. 122) in the Little Taylor Mountains. For this record, it is assumed that at least a little gold is present in the altered rocks.
