Deposit THE ORE BODIES RANGE IN SIZE FROM SMALL LENSES TO 20 FT WIDE BY 5 TO 25 FT LONG AND 100 FT OR MORE DOWN THE DIP WITHIN A HORIZONTAL DISTANCE OF 500 FT ON THE LARGER FAULT ZONE THREE SHOOTS HAVE BEEN STOPED TO A DEPTH OF ABOUT 100 FT, AND ONE WAS FOLLOWED FROM THE 100 TO THE 200 LEVEL. ON THE PARALLEL FAULT TO THE NORTHWEST, THE ORE BODIES ARE OF SMALLER SIZE AND LOWER GRADE.
