I agree MrsC, but I'm also of the opinion that most of the shallow drilling (although ongoing) and most (if not all) of the trenching is completed...these are the only results that we are currently privy to.
Not sure what the reasons are...could be pressure from the SEC to release something, or could be a strategy to not release anything too big, too soon.
Regardless, I believe that there is much more that they're sitting on, waiting to release, and that these results do not relate chronologically to the order in which the drilling program has progressed.
So you are bang on IMO. There is much more to come but as they see fit to release it.
Again, just my thoughts.
