The Kusturin and Johnson is a 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 (Reserve-Resource): Reserves = None reported.
Comment (Reference): Primary Reference = Martin and others, 1915
Comment (Geology): Age = Cretaceous or younger; the veins cut Cretaceous graywacke.
Comment (Production): Production Notes = No production is known.
Comment (Geology): Geologic Description = Three, quartz-pyrite veins intrude Cretacous Valdez Group graywacke and slate (MacKevett and Holloway, 1977). The veins are 2 to 6 feet thick. Martin and others (1915) visited one of the veins that strikes N27E and dips 40W. It was 71 inches thick and contained pyrite, chalcopyrite, and graphite. No assay results are reported.
Comment (Deposit): Other Comments = This prospect is within Kenai Fjords National Park; the area is closed to mineral entry.
Comment (Deposit): Model Name = Low-sulfide, Au-quartz vein (Cox and Singer, 1986; model 36a)
Comment (Workings): Workings / Exploration = Some minor stripping was reported by Martin and others (1915).
Comment (Exploration): Status = Inactive
