In late 2007, Constantine intersected high-grade copper and zinc mineralization over a width of 14 meters at the RW zone (CMR07-07). The drill was then moved over 400 meters to the east, where discovery hole CMR07-09 intersected 24.2 meters of massive sulphide at what is now referred to as the South Wall zone.

In 2008, Constantine followed up on the initial South Wall discovery with hole CMR08-11, which intersected 36.3 meters of massive sulphide, followed by a second 20.4 meter massive sulphide zone, followed by a third 14.4 meter massive sulphide zone. The cumulative width of the three stratigraphically ‘stacked’ zones in this drill hole is 71.1 meters. Twelve holes (2 abandoned) for a total 4,395 meters were completed during 2008, yielding a total of seventeen mineralized intercepts. The exploration to date indicates a minimum lateral extent of South Wall mineralization of ~300 meters horizontally by ~300 meters vertically in three zones and all zones are open to expansion.  Due to the continuous drilling success at the South Wall zone, and limited drill resources at the time, no holes followed up on the 2007 RW zone intersection –which is also open at depth and along strike.

The South Wall zones occur on the steep limb of a large anticlinal fold, whereas the CMR07-07 RW zone intercept is on the shallow dipping upright limb (see schematic fold diagram). The presence of massive sulphide on both sides of the fold indicates a sizeable massive sulphide system, with the zones on each limb offering excellent opportunity for further expansion.
