Comments on the geologic information

  • Geologic Description = Hummel (1962 [MF 247]) described old prospect pits south of Banner Peak near hill elevation 592 that contained lead- and antimony-bearing minerals, presumably galena and stibnite. The area was included in a soil geochemical survey conducted by BHP in 1990 and was anomalous in arsenic and gold. Drilling and trenching in 1992 by Newmont Mining Company identified replacement masses of tabular albite almost pegmatoid in appearance. These masses contained arsenopyrite and assayed as much as 0.25 ounce of gold per ton in zones as much as 5 feet thick. The masses appear to be podiform, and continuity was not demonstrated. They resemble the albitic replacement deposits at Alpha Ridge (NM171), Goodluck Gulch (NM202), and the Walsh Cut (NM214) at Rock Creek. Country rock in the area south of Banner Peak is mainly graphitic schist and quartzite (Bundtzen and others, 1994).
  • Age = Mid-Cretaceous or younger; superimposed on schist metamorphosed during the mid-Cretaceous.
