Geographic coordinates

Geographic coordinates: -130.03786, 56.04588 (WGS84)
Relative position The Border prospect is in Section 24 at an elevation of about 650 feet, adjacent to the Alaska-British Columbia boundary (Elliott and Koch, 1981, p. 16, loc. 61). The property apparently straddles the old road that led to the boundary roadhouse, now in ruins. The location is accurate to within 0.1 mile.

Comments on the geologic information

  • 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?).
