The Silver Star is a silver, gold, lead, and zinc 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.

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 (Reference): Primary Reference = Buddington, 1929
Comment (Workings): Workings / Exploration = 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.
Comment (Deposit): Model Name = Polymetallic veins
Comment (Deposit): Other Comments = Prospect was originally staked in 1923.
Comment (Geology): Geologic Description = 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).
Comment (Exploration): Status = Inactive
