I have seen a bunch of figures on the drilling rates, though I will state up front that I think miskealp has a better handle on this than I do.

I seem to recall reading that the new drills will drill between 50-70 meters/shift. (Though this depends on the hardness of the rock, and I have seen it suggested that they can drill even more.)

For my (albeit simplified) calculations, I assumed two holes/week. If we take your suggestion of 120 meters/day and a hole depth of 300 meters then we have about 2.5 days per hole. Add in a day for transport (though if I recall correctly, they can be set up in eight hours) and we are at more-or-less two holes per week.
