The Chickamin is a copper, lead, and zinc 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 (Reference): Primary Reference = Buddington, 1929
Comment (Deposit): Model Name = Polymetallic veins
Comment (Deposit): Other Comments = Prospect could not be located 1972-73. Site is in Misty Fiords National Monument.
Comment (Exploration): Status = Inactive
Comment (Geology): Geologic Description = The country rocks in the area of the Chickamin prospect are metamorphosed pelitic strata of the Jurassic or older Mesozoic Hazelton Group that are underlain and locally intruded by the Triassic Texas Creek Granodiorite. Both the Hazelton and Texas Creek, in turn, are intruded by the Eocene Hyder Quartz Monzonite (Smith, 1977; Berg and others, 1977, p. 15-18, 22-23).? Buddington (1929, p. 100) describes the deposit as a quartz stringer lode and a three-foot-thick quartz fissure vein in graywacke. The stringers and vein contain galena, chalcopyrite, sphalerite, pyrite, and a little pyrrhotite and tetrahedrite. In 1972-73, a U. S. Bureau of Mines field team searched for but could not find the prospect, which probably was covered by snow (Berg and others, 1977, p. 84). A grab sample from a foot-thick granitic dike in the area near the prospect contained traces of pyrrhotite and goethite.
