What assumptions are you using for the Q1 ore grade loaded to the pad?
If I assume they get the same oz loaded as Q4 given the historical recovery rate of the heap leach I come up with:
Au: 8.0k oz
Ag: at 170k oz
So almost identical to yours. However in Q4 they were loading higher grade material on the new heap leach so the recovery was a bit higher for the quarter. My question is how long does that higher recovery last going forward?
