It seems to me that KXL has prioritized Hercules as their main target for proving up a resource in the near future as they have kept several drills on this site through out the drilling program.
The other 5 drills ( I believe ) are testing new targets which the Geo's determined warranted drills at these locations.
I am certain that management has done a in depth spread sheet as to cost of this strategy so that funding remains a non issue during these volatile times and that within a certain time frame prior to running low on funding thay will have an agreement with a major to fund further exploration of their many other targets. Due to the size of KXL's holdings and the fact that many other mines are peppered all around KXL, I think that over time KXL has the potential to prove up a number of mines. JMO
