I'm a little surprised that they are not using helicopter support for one or two of the units to quickly move to each of the regional targets and pop a hole or two and then move off to the next target while awaiting assays.  Remember we are now talking about moving kilometers between targets in rugged terrain.   Building drill roads to each of the target areas is a slow process and almost commits you to 4 or 5+ holes while waiting for road development to the next regional target.   

If they don't have helicopter support my guess is that they will continue moving incrementally North and South from FDN.  Hence El Tigre and Papaya being the first regional targets that they drilled.   I also suspect that that they may drill deep under BLP since they have some bigger drill on the property now and from what I can tell, most of the BLP drilling were shallow.

 Just some thoughts.
