Below the current area of mining and the en echelon set of stockwork veins defined by the
97-A-Deep East set, there is potential for a new en echelon array of east-stepping stockwork
veins 500-1500 feet down dip to the north-northwest in the SAM unit (Figure 18). If a new
set of veins is developed, it may be linked to vein systems currently being mined by
dominant 16-type shear veins such as the C and 96 veins, just as sets of stockwork veins are

linked by shear veins on upper mine levels. Following these shear veins out to depth with
drilling may allow identification of such a vein system
