Comments on the ore body information

  • Sherman vein is a split from the Union vein which extends SW through Hidden Treasure ground to connect with Tiger-Poorman vein. The Sherman vein may also be a SE extension of the Custer Vein of the Tamarack and Custer mine.

Controls for ore emplacement

  • Mineralized zone bounded to west by Marsh and Oreano Faults, and to the east by the Swan Fault.
  • Rake of orebodies parallels fault and vein intersections.
  • Sherman vein consists of partly oxidized lead ores in fractures in quartzite with little gangue; grade increases as bedding flattens.
