The Charles is a lead, zinc, silver, gold, and 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.

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 (Reference): Primary Reference = Westgate, 1922
Comment (Commodity): Gangue = quartz porphyry
Comment (Deposit): Model Name = Polymetallic veins; ?Porphyry copper, North America(?)
Comment (Deposit): Model Number = 22c; 17(?)
Comment (Geology): Geologic Description = The country rocks in the general area of this occurrence are pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group, which are underlain and locally intruded by the Triassic Texas Creek Granodiorite. The Hazelton and Texas Creek rocks are intruded by the Eocene Boundary Granodiorite, and all of these rocks in turn are cut by still-younger Tertiary lamprophyre dikes (Smith, 1973, 1977; Koch, 1996).? the deposit (Westgate, 1922, p. 129, 139-140) consists of sulfide minerals disseminated in sheared, silicified granite porphyry that is cut by small, barren quartz veins. The sulfides are sphalerite, galena, pyrite, and chalcopyrite. Assays reportedly showed small amounts of Au and Ag.
Comment (Exploration): Status = Inactive
