I don't quite understand how this much mineralized rock which is within the pit shell was not drilled to a higher confidence level for inclusion to the FS.

It seems they did not want the BFS to take longer, the aim was to get the clock running as opposed to presenting the most complete and up to date data. As has been mentioned they had enough information and the people that matter have a good idea whats there. Those ten drills etc will be on Tech's dime when the snow melts.
