Property was probably originally staked in early 1920's. Taken over by Brigadier Mining Company sometime before 1929 (Buddington, 1929, p. 83).
Location: The Cripple Creek prospect is in the north part of Section 35 at an elevation of about 400 feet, between the Salmon River Road and an abandoned aerial tramway (Elliott and Koch, 1981, p. 17, loc. 69). The location is accurate within about a quarter of a mile. Also see Additional Comments field, below.
Geology: The country rocks in the area of this prospect are the 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 Texas Creek and Hazelton rocks; and still-younger Tertiary lamprophyre dikes, which cut all the other rocks (Smith 1973, 1977; Koch, 1996). There appear to be two main types of deposits (Buddington, 1925, p. 74; 1929. p. 83-84). (1) A quartz fissure vein up to 8 feet thick in the footwall of a 10-15-foot thick sheeted shear zone in granodiorite. The vein contains considerable galena and smaller amounts of pyrite, chalcopyrite, sphalerite, and tetrahedrite, and was explored by a 45-foot adit and a short crosscut. (2) Fissured and brecciated zones comprising sulfide-bearing quartz veinlets and sulfide-impregnated granodiorite. Pyrite is the principal sulfide in these zones, accompanied by a little galena and sphalerite.
Workings: Property was developed in 1920's by a 45-foot adit and a short crosscut.
Alteration: Sheared granodiorite is partly replaced(?) by disseminated sulfides.
