Can anyone confirm whether mmb are utilising 2 or 3 drills in thier current drill program ????

Trying to work out a timeline for how long it takes them on average, from the start of a new drill to the finish at depth. ???

The reason being is that it didnt seem to take long between confirmation of a dry hole (hole 3),to the more positive confirmation of mineralisation at (hole 4).

I got the impression that hole 4 was already being drilled whilst they were finalising hole 3.
