So that would be an average of approx 30-35 m per 24 hour period. Lower than the 40m per day average I use, but they are drilling deep up there, I assume. IMO, its also hard rock the chromite is associated with. I have drilled the same type of rock on my property to see sparks fly from the drill. Precambrian and ultramafic are some of the hardest rocks and that is what some of the chromite deposits are found in.

Bad for flies here this year too!
