Comments on the geologic information

  • Geologic Description = About a dozen exploration shafts, some almost 100 feet deep, were dug on oxidized, limonite-stained, decomposed bedrock near a schist-marble contact in the headwaters of Newton Gulch (Smith, 1909; Mertie, 1918 [B 662-I, p. 425-449]). The deposit consists of pyrite in quartz stringers and as disseminations on the schist. Composite samples averaged about 0.25 ounce of gold per ton (Mertie, 1918; Cathcart, 1922). Bedrock in Newton Gulch is mostly amarble and schist, probably of early Paleozoic protolith age (Hummel, 1962 [MF 247]; Till and Dumoulin, 1994; Bundtzen and others, 1994). The marble-schist unit is in contact with another schist unit near this prospect.
  • Age = Mid-Cretaceous or younger; veins cut schist metamorphosed in the mid-Cretaceous.
