The McCall is a lead and silver 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 = Minor surface workings. Samples contain up to 55 percent lead and 6 ounces of silver per ton (Berg and Cobb, 1967).
Comment (Reference): Primary Reference = Cobb, 1978 (OFR 78-1062)
Comment (Deposit): Other Comments = This site is in Denali National Park.
Comment (Geology): Geologic Description = Little information about this prospect has been made public. Apparently, it consists of galena-bearing quartz-carbonate veins that cut Devonian metavolcanic schist and phyllite. Samples contain up to 55 percent lead and 6 ounces of silver per ton (Berg and Cobb, 1967).
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Polymetallic veins (Cox and Singer, 1986; 22c)
Comment (Geology): Age = The veins are Devonian or younger.
