Just a thought from an experienced family of rig people who have worked all over this world. We feel that the holes dilled are not on main target. By the map the are 11 holes off target that only need a small rig to reach depth. The deep rig more than likely uses a larger pipe diameter to core and therefore you would not be able to enter the same hole to deepen them. It stands to reason to start from surface with the deep rig.
