Comments on the geologic information

  • MN OXIDES ASSOCIATED WITH CALCITE OCCUR AS REPLACEMENTS AND FILL MATERIAL IN FRACTURES AND BRECCIAS IN ANDESITE.
  • ORE OCCURS IN FAULTED AND BRECCIATED ZONES IN ANDESITE AND ANDESITE BRECCIA. THESE ZONES ARE INTRUDED BY A YOUNGER PORPHYRITIC ANDESITE DESTROYING PART OF THE ORE BODY. TWO NW TRENDING TABULAR ZONES COMPRISE THE LOGAN MINE THE NORTH ZONE STRIKING N70W IS 560M LONG. 80 M OF ITS STRIKE LENGTH IS DESTROYED BY INTRUSION. THE SOUTH ZONE, STRIKING N40W IS 490M LONG, 140M OF ITS STRIKE LENGTH IS DESTROYED BY INTRUSION. THE MAX WIDTH EXPOSED ON OUTCROP IS 35M, AVERAGING 32M. THE MAX THICKNESS EXPOSED IS 21M, AVERAGING 15M IN THE NORTH ZONE AND 18M IN THE SOUTH ZONE.
