Prospect was originally staked in 1923.
Location: The Silver Star prospect is in Section 12 about 2.7 miles east-northeast of the outlet of Texas Lake. It consists of an upper zone at an elevation of about 3750 feet, and a lower zone at an elevation of about 3000 feet (Elliott and Koch, 1981, p. 14, loc. 47). The map coordinates are for the approximate midpoint between the zones and are probably accurate within about a quarter of a mile.
Geology: The country rocks in the area of the Silver Star prospect are pelitic metasedimentary and andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group, which is underlain and locally intruded by the Triassic Texas Creek Granodiorite (Smith, 1977; Koch, 1996). The deposit (Buddington, 1929, p. 97) lies along the contact between Texas Creek Granodiorite and overlying Hazelton argillite and consists of quartz fissure veins on both sides of the the contact. Two veins as much as a foot thick in a two-foot wide shear zone in the granodiorite (Buddington, 1925, p. 89-90) contain mainly galena and pyrite and were explored by a 30-foot adit. About 100 feet above the adit entrance the zone is about 7 feet wide. It consists of heavily mineralized quartz as much as 9 inches wide in the footwall and more than a foot of sparsely mineralized quartz in the hanging wall (Buddington, 1929, p. 97). The veins in the argillite consist of quartz stringers approximately parallel to the bedding that locally contain galena, sphalerite, and pyrite, and smaller amounts of pyrrhotite, arsenopyrite, and freibergite. A select sample from the granodiorite lode is said to have assayed an ounce of gold per ton (Buddington, 1925, p. 89-90).
Workings: Prospect was explored, probably in the 1920's, by a 30-foot adit. A select sample from the granodiorite lode is said to have assayed an ounce of gold per ton.
