The West Gladiator 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 of five chip samples of greenstone assayed 910 ppm Cu and 4.3 ppm Ag. A sample from a quartz-epidote-chalcopyrite-malachite vein yielded up to 22 ppm Ag, 1.0 percent Cu, and 250 ppm Zn (Resource Associates of Alaska, 1976).
Comment (Deposit): Model Name = Porphyry Cu ? or Polymetallic vein ? (Cox and Singer, 1986; models 17 ? or 22c ?)
Comment (Deposit): Other Comments = Site is in Lake Clark National Park and Preserve.
Comment (Production): Production Notes = No production
Comment (Geology): Age = Tertiary or younger.
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = Greenstone, metasediments and volcanic flows (?), are intruded by a Tertiary medium-grained hornblende-biotite granodiorite. The rocks are hornfelsed near intrusive contact. Fractures in the greenstone near intrusive contact contain malachite and chalcopyrite. Quartz veins containing epidote, chalcopyrite, and malachite cut intrusive rocks near contact also. One of five chip samples of greenstone assayed 910 ppm Cu and 4.3 ppm Ag. A sample from a quartz-epidote-chalcopyrite-malachite vein yielded up to 22 ppm Ag, 1.0 percent Cu, and 250 ppm Zn (Resource Associates of Alaska, 1976).??
Comment (Reserve-Resource): Reserves = No reserves
Comment (Reference): Primary Reference = Resource Associates of Alaska, Inc., 1976
