Site probably originally staked in about 1923. Some reports also include references to the Standard claims, staked in 1931(?), that probably include the Nothiger prospect.
Location: The Nothiger prospect is in the northeast corner of Section 24 at an elevation of about 2500 feet . It is on the steep west wall of the valley just below the foot of Casey Glacier (Elliott and Koch, 1981, p. 15, loc. 53). The location is probably accurate within a quarter of a mile. Also see Additional Comments field, below.
Geology: The country rock in the area of this prospect is Triassic Texas Creek Granodiorite, which regionally underlies and locally intrudes pelitic metasedimentary and subordinate andesitic metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group (Smith, 1977; Koch, 1996). The deposit (Buddington, 1929, p. 94) comprises an extensive shear zone 20-40 feet thick in granodiorite that contains a quartz vein and many quartz stringers. The main vein is 2.5-6 feet thick and contains a little galena and pyrite. The deposit was explored by a 12-foot crosscut adit driven through the main vein into the granodiorite footwall.
Workings: The deposit was explored in the 1920's by a 12-foot crosscut adit driven through the main vein into the granodiorite footwall.

Commodities (Major) - Pb
