They are currently mining at nearly double the rate they are milling at (March quarter 1636 mined versus 876 milled) so logically the stockpiles should mount and they should come to an end of mining well before all of the milling / processing is completed.

Also the waste / ore ratio for the March quarter was 1.6:1 which was a big improvement on the December quarter of 2.9:1 but still short of their expected target going forward of 1.1:1. In theory this would mean that the gap between mining and milling should increase if anything.
