Comments on the geologic information

  • IN A SHALLOW OPENING BELOW THE MAIN SHAFT RICH GOLD WAS ENCOUNTERED IN THE OXIDIZED ZONE WHICH EXTENDS DOWN TO 75 FEET BELOW THE SURFACE. THE SULFIDE ZONE IS PREDOMINATED BY ARSENOPYRITE AND PYRITE. WHERE THE ALTERED QUARTZITE HAS BEEN SHATTERED STRINGERS OF IRON OXIDE CARRY FREE GOLD. THIS OCCURS BETWEEN THE 35 AND 100 FOOT LEVELS OVER A 4 FOOT WIDE ZONE WHICH STRIKES N20W, AND DIPS 35 DEGREES NE. (EMMONS, W.H. 1910). THERE ARE TWO PRINCIPLE MINERALIZED CONES ALONG FRACTURES FAULT ZONES
