Comments on the geologic information

  • MINERAL WEIGHT PERCENTAGES FROM WILBAND, REFERENCE M001-002.
  • SOURCE OF INFORMATION: REFERENCES G001-3,7-9,10-11. THE CONGLOMERATE CHANGES TO SANDSTONE AT THE THINNER MARGINS OF THE LENS. BECAUSE THE PERMEABILITY OF THE SANDSTONE IS LESS, ORE IS CONFINED TO THE CONGLOMERATIC PORTION OF THE LENS.
