Depends on the depth of each hole... I understand this new drill is capable of 100+ meters/ day
For deliniation drilling they could drill several directions from the same setup... n...s...e..w @ 45 deg....center @ .90 if required... This would dependent on the depth to kimbie from the surface.
If they start definition drilling it will be for only one reason.... its a minable deposit... Grade, size of stones etc.
