It is my understanding that before step two they split the cores and run them under a portable spectroradiometer, the assays are more precise but they should have a good understanding as to whether the drill is hitting well before the gold is sent to the lab.
Management has also done bulk sampling to demonstrate that the assays are about 50% too low.
43-101 we won't be seeing for some time, I imagine. We will all be too rich to know and care.
