But mill ground through 2.01 million tonnes in Q1 & Q2, not 1.89...

But mill ground through 2.01 million tonnes in Q1 & Q2, not 1.89 or am I missing something? If the machine has a 3.0Mtpa capacity then that leaves less than a third of that capacity remaining for half the year. Or is it that the stated 3.0Mtpa capacity shouldn't be taken literally? Also Q2 report states lower ore grade than Q1.
What am I missing?
I do not mind being embarrassed in order to understand.
