The Stoner-Clegg-O'Rourke 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 (Geology): Geologic Description = The country rocks in the area of this prospect are pelitic metasedimentary and subordinate andesitic (greenstone) metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Triassic Texas Creek Granodiorite, which underlies and locally intrudes the Hazelton; the Eocene Boundary Granodiorite, which intrudes the Hazelton and Texas Creek rocks, and still-younger Tertiary lamprophyre dikes, which cut all the other rocks (Smith, 1973, 1977; Koch, 1996).? the deposit (Buddington, 1929, p. 88) consists of greenstone containing calcite veinlets with sphalerite, pyrite, and galena, and small amounts of pyrrhotite, chalcopyrite, and tetrahedrite. Some of the greenstone contains disseminated pyrite and pyrrhotite.
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Buddington, 1929
Comment (Workings): Workings / Exploration = Deposit was explored by opencuts and a 75-foot adit, probably in the 1920's.
Comment (Deposit): Model Name = Polymetallic veins
Comment (Deposit): Other Comments = Probably originally staked in early 1920's
