Geologic information

Identification information

Deposit ID 10000244
MRDS ID A010282
Record type Site
Current site name Texas Discovery

Geographic coordinates

Geographic coordinates: -130.1987, 56.06366 (WGS84)
Relative position 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.

Comments on the geologic information

  • 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).
