Geographic coordinates

Geographic coordinates: -130.07075, 56.02577 (WGS84)
Relative position The approximate location of this unverified mineral occurrence, known in 1981 (Elliott and Koch, 1981, p. 17, loc. 68) only from a U.S. Bureau of Mines claim map (U.S. Bureau of Mines, 1978), is at the western edge of Section 26, at the southwest foot of Mineral Hill. The site is at an elevation of just under 200 feet, and adjacent to the road along the east side of Texas Creek. The location is probably accurate within about a quarter of a mile.

Comments on the geologic information

  • Geologic Description = The country rock in the area of this site is Triassic Texas Creek Granodiorite, which underlies and locally intrudes pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Eocene Boundary Granodiorite, which intrudes the Hazelton and Texas Creek rocks; and still-younger Tertiary lamprophyre dikes, which cut all the other rocks (Smith, 1973, 1977; Koch, 1996). Other than the commodities reported on a U.S. Bureau of Mines claim map (U.S. Bureau of Mines, 1979), no geologic information about this site was publicly known in 1981.
