The process of drilling a hole involves speculating where the orebody is located and drilling to intersect it at some predetermined depth. The location, azimuth and dip of hole 49 would not be conducive to intersecting the convegence zone. In the same fashion, a hole directed to intersect the orebody at some depth such as 15 or 18 hundred meters would not be likely to hit said convergence zone. They have stated that they are chasing this convergence zone at depth and it follows then that they would not expect to intersect anything prior to it. On the flip side of this, maybe they hit another different zone on the way down, or even maybe they are in this zone already and have hit big time there. ALL speculation at this point, but always fun when the possibilities are all positive.
