This does make a lot of sense to me, as well super. IMO, we had enough coorelation, sulphide to Quantec color, at the Canchete to give us a good idea what the anomaly may hold in the terms of sulphides. These perimeter holes could be the smaller ones because they were designed for test sampling and testing the extents of the anomaly. You are most likely not gonna drill there again, unless you find something that has to be redrilled. The shape of it is supposedly a bowl, so the most logical thing to do would be get the deeper drill, that has a larger casing, do the inside portion of the anomaly.
IMO
