Actually, they can Dosco, that's the whole point. Take the drill results announced on Dec. 12, 2011: 63m @ 14g/t, including 0.9 m @ 858 g/t. If you take out the single high grade sample, you're left with 61 m of low grade material...that's assuming there are no other samples that would further skew the results. Continuous mineralization is very different than averaging a few high grade samples over a wide interval. Although, without all the assay results it is difficult to tell exactly what is going on in these holes.
Hammer is correct. Unless the twinned holes show continuous mineralization over a wide interval, it is highly possible there will be a significant reduction in tonnage and ounces in the revised estimates.
