  • General form LENS
    Strike N 55 W
    Dip NEAR VERTICAL

Comments on the geologic information

  • ONE 4-FOOT SAMPLE, TAKEN ACROSS THE MINERALIZED ZONE IN THE EASTERNMOST CUT, ASSAYED 27.3 PERCENT MN. WORK HAS BEEN INSUFFICIENT FOR DETERMINING THE STRIKE LENGTH OF THE DEPOSIT. THE BEST MINERALIZATION OCCURS IN THE WESTERN MOST CUT, AS THE ZONE BECOMES MORE SILICEOUS TO THE EAST.
