Texas Discovery

The Texas Discovery is a silver, lead, 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.

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 (Deposit): Model Name = Polymetallic veins

Comment (Reference): Primary Reference = Buddington, 1929

Comment (Deposit): Other Comments = Occurrence was originally staked in 1923.

Comment (Geology): Geologic Description = The country rock in the area of this occurrence is Triassic Texas Creek Granodiorite, which regionally underlies and locally intrudes pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group (Smith, 1977, Koch, 1996).? the deposit (Buddington, 1925, p. 74; Elliott and Koch, 1981, loc. 48) consists mainly of a quartz fissure vein 1-14 inches thick in granodiorite. The vein contains galena, pyrite, pyrrhotite, and minor chalcopyrite. An assay of a picked sample of this vein reportedly showed 30% Pb, about 1.06 oz Au per ton, and a little silver. A nearby quartz stringer 4 inches thick contains galena and chalcopyrite (Buddington, 1929, p. 98).

Comment (Workings): Workings / Exploration = An early assay of a picked sample of the main vein reportedly showed 30% Pb, about 1.06 oz Au per ton, and a little silver.

Comment (Exploration): Status = Inactive
