Ann: SM 71 F2 Well Drilling Ahead, page-3

Well you know the answer to that, don't you?   If successful: "The secondary target, the B65 Sand, has the potential to add significant reserves to the SM71 project. Collarini Associates (“Collarini”), an independent petroleum engineering consultant (based in Houston, Texas) has attributed 1.6 million barrels of oil equivalent* net to Byron as prospective resources in the B65 Sand."

That's about 2.5 times the Primary target.  One would expect that news would put a small lift in the SP.
