Comments on the geologic information

  • Geologic Description = Jansons and others (1984) reported a 30-ft-wide, more than 100-ft-long shear zone in graywacke of the Tertiary Orca Group. The shear zone contains fractured graywacke cemented by pyrite, arsenopyrite, and quartz. Eight grab samples contained up to .012 oz/ton Au, less than 0.2 to 0.6 oz/ton Ag, and up to 0.2 percent As.
  • Age = Paleocene or younger; shear zone cuts graywacke of the Tertiary Orca Group.

Comments on the workings information

  • Workings / Exploration = Eight grab samples contained up to .012 oz/ton Au, less than 0.2 to 0.6 oz/ton Ag, and up to 0.2 percent As. Jansons and others (1984) indicate low potential for mineral development.
