" To me it would take more than these 2-3 holes to warrant that kind of boost to the resource estimate?"

Logic would be that they would place the two wedges to confirm both other dimensions (horiz/vert). As it stands they have a big nugget. If they could confirm that breccia out to 25+ meters both vertically and horizontally, and it was mineralized, you have something very substantial. Of course it does not prove up anything at that point, but it sure would be worth betting the farm on.
