Geographic coordinates

Geographic coordinates: -130.2937, 56.04366 (WGS84)
Relative position The Hummel Canyon prospect is at an elevation of about 2500 feet in Section 20 about 0.2 mile northeast of the mouth of Hummel Canyon and 0.4 mile southwest of Disappearing Lake (Berg and others, 1977, p. 92; Elliott and Koch, 1981, p. 12, l0c. 35). This location is probably accurate to within about a quarter of a mile.

Comments on the geologic information

  • Geologic Description = The country rocks in the area of the Hummel Canyon prospect are Triassic Texas Creek Granodiorite that underlies and locally intrudes pelitic metasedimentary and andesitic metavolcanic rocks of the Jurassic or older Mesozoic Hazelton Group (Smith, 1977; Berg and others, 1977, p. 15-18; Koch, 1996). ? the deposit consists of a pyritic silicified zone up to a foot thick , associated with slightly pyritic hornfels wallrock (Berg and others, 1977, p. 92). Samples of the silicified zone and the pyritic wallrock contained negligible amounts of Cu, Pb, Zn, Mo, and Ag.
