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 (Exploration): Status = Inactive

Comment (Reference): Primary Reference = Buddington, 1929

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 andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group (Smith, 1977; Koch, 1996).? the deposit (Buddington, 1929, p. 93) consists of a quartz vein up to 3 feet thick in a shear zone in granodiorite. The vein, exposed in outcrop for 250-300 feet, is mostly barren, but locally contains pockets and bands of chalcopyrite, minor galena and pyrite, and barite.

Comment (Deposit): Other Comments = Occurrence originally staked in 1923.? Some descriptions of this occurrence also include references to the McVey claims (Cobb, 1978, p. 70).

Comment (Deposit): Model Name = Polymetallic veins
