Just because the airbourne has been completed, does not mean the final analysis has been completed - it takes considerably longer especially when done over a very large area - this was done over all of Probe's claims.
In terms of the core, I just called the office, their core shack is at the camp - when the core looks promising it is all sent out. If not, a random sampling, as in this case, is sent out. If it had turned out to be flat as what the preliminary indications were, sending out the whole lot would have been a complete waste of money.
Probe proceeded as per industry standards - perhaps you should all acquaint yourselves with these or ask questions before making these negative comments.
