Occurrence was originally staked in 1923.
Location: The Texas Discovery occurrence is in Section 13 at approximately 2000 feet elevation. It is just above the old wagon road that follows the West Fork of Texas Creek, and about 2.3 miles below the outlet of Texas Lake (Elliott and Koch, 1981, p. 14, loc. 48). The location probably is accurate within about a quarter of a mile.
Geology: 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).
Workings: 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.
