The NOT anomoly is very clear as well..... but you can see that the orientation / dip / depth are not known untill the drilling is done... NOT had several holes that ran over , under and just missed ....
I think their plan is to go some more geo work prior to drilling, in the meantime NOT's drilling is providing more info which cost PRB nothing but time.
When/ if the drill finally hits PRB could have one heck of a run with such a small float.
