Comments
Comment (Workings): Workings / Exploration = Prospect was explored by a 70-foot adit, probably in the 1920's.
Comment (Reference): Primary Reference = Buddington, 1929
Comment (Exploration): Status = Inactive
Comment (Deposit): Model Name = Polymetallic veins
Comment (Deposit): Other Comments = Property originally staked in early 1920's
Comment (Geology): Geologic Description = The country rocks in the area of the Border prospect are pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Triassic Texas Creek Granodiorite, which underlies and locally intrudes the Hazelton; the Eocene Border Granodiorite, which intrudes the Hazelton and Texas Creek rocks; and still-younger Tertiary lamprophyre dikes that cut all these rocks (Smith, 1973, 1977; Koch, 1996).? the deposit (Buddington, 1929, p. 90) consists of gash (fissure) veins of quartz in a shear zone in slate and graywacke between two granodiorite porphyry dikes. The quartz contains galena, pyrite, sphalerite, and a little chalcopyrite in sulfide shoots up to 6 inches thick, and considerable carbonate (calcite?).
