The Keno is a zinc, silver, lead, copper, and 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.

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 (Deposit): Model Name = Polymetallic veins
Comment (Reference): Primary Reference = Buddington, 1929
Comment (Workings): Workings / Exploration = Early workings included a 50-foot adit.? An early assay, presumably of the best ore, showed 0.6 oz Au and 3 oz Ag per ton, and 48% Pb.
Comment (Geology): Geologic Description = The country rocks in the area of the Keno prospect 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 (Smith, 1977; Koch, 1996).? In 1925, Buddington (p. 94) described the deposit as quartz fissure veins 2-4 feet thick that cut granodiorite and contain galena and other sulfides. A specimen, presumably of the best ore, contained 0.6 oz Au and 3 oz Ag per ton, and 48% Pb. ? In 1929, Buddington (p. 108) reported an adit driven along a quartz vein up to 4.5 feet thick in Texas Creek Granodiorite. The vein had been traced on the surface for about 400 feet, and contained oreshoots of solid sulfides as much as 7 inches thick comprising galena, pyrite, chalcopyrite, sphalerite, and tetrahedrite. The quartz also carries disseminated pyrite and, locally, some barite.
Comment (Exploration): Status = Inactive
