Skier, my amateur interpretation of it is that maybe they're currently trying to use these drill holes more to define where the gold is and less to determine the grade. Brattymack was saying that in the future their hopefully might be enough of those red stripes on the map that it would look something like a zebra pattern.
So, it seems to me that drilling in the direction that they presently are may help in trying to put more of those red stripes on the map (in other words, prove up more tonnage) and maybe they will rely more on bulk sampling to determine grade. We already know that the drill cores underestimate the grade, but they are nevertheless useful in determining the whereabouts of the actual gold.
This is nothing but conjecture on my part, though. This is the impression I got when Brattymack explained the whole deal with the red stripes and what not. I could be way off base here so I would like to hear from someone who knows what they're talking about.
