Comments on the workings information

  • DEVELOPMENT CONSISTS OF A CROSS-CUT EAST 136 FT. TO VEIN; DRIFT N. 240 FT TO A 200-FT. VERTICAL SHAFT, FROM SURFACE WHICH IT INTERSECTS AT THE 50 FT. LEVEL. ON THE 200-FT. LEVEL OF SHAFT, CROSS-CUT 32 FT. TO THE FOOT WALL OF VEIN. ON THE TUNNEL LEVEL DRIFT SOUTH 574 FT FROM THE CROSS-CUT. AT 510 FT. FROM THE CROSS-CUT, DRIFT INTERSECTS AN INCLINE SHAFT FROM SURFACE. THIS SHAFT IS SUNK ON A 60 DEG INCLINATION FOR 260 FT. TUNNEL LEVEL 120 FT. BELOW THE SURFACE. IN THE TUNNEL AN ORE SHOOT BEGINS SOME 50 FT. SOUTH OF THIS SHAFT AND APPEARS TO EXTEND NORTH SOME 170 FT., VARYING IN WIDTH FROM 3 FT. TO 12 FT. IT WAS APPROXIMATELY 200 FT. NORTH FROM THIS SHOOT TO ANOTHER SIMILAR ONE REPORTED TO BE 200 FT. LONG. ON THE 170-FT. LEVEL OF INCLINE SHAFT, DRIFT NORTH ABOUT 60 FT. TO HOLE RAISE FROM 210 FT. LEVEL. ON 210-FT. LEVEL, DRIFT NORTH ABOUT 280 FT. SOUTH 30 FT. THE NORTH DRIFT PICKED UP THE SOUTH SHOOT SHOWING SOME SULFIDES. ON 260-FT. LEVEL, DRIFT NORTH 90 FT. AT 127 FT. SOUTH
  • OF CROSSCUT, A WINZE SUNK TO A VERTICAL DEPTH OF 100 FT., DEVELOPING 6 FT. OF ORE. ABOUT 1000 FT. NORTH OF THESE WORKINGS AND IN THE NEXT CANYON A VERTICAL SHAFT HAS BEEN SUNK 150 FT. REPORTED THAT ON THE 150 LEVEL, A DRIFT WAS DRIVEN NORTHWEST 140 FT. AND CROSSCUT FROM THE FACE NORTHEAST, WITH A DRIFT FROM THE CROSSCUT SOUTHEAST, A TOTAL OF 400 FT. ON THIS LEVEL. SEVERAL SHORT TUNNELS AND OPEN-CUTS HAVE BEEN MADE IN THIS CANYON. THESE WORKINGS SHOW A VEIN ON EACH SIDE OF A MONZONITE DIKE WHICH IS ABOUT 100 FT. WIDE. SOME 750 FT. WEST OF THIS CANYON SEVERAL TUNNELS HAVE BEEN DRIVEN, ONE OF WHICH IS ABOUT 700 FT LONG. THIS WORK WAS DONE ON A VEIN, STRIKE N. 70 DEG W., WHICH APPEARS TO FORM A JUNCTION WITH THE VEINS MENTIONED ABOVE, IN THE CANYON, MILLSITE.
