Yes, I think it's crazy. The only thing that makes me a bit uneasy is that their costs per oz are very high ($US660) for such a high grade (5.5g/t) open cut operation. I suspect it has to do with the fact that they're only getting 87% recovery (anyone know why?).
That being said, given the stockpile is at 3g/t, I can't see them making too much dough from Andorhinas until the underground comes on stream.
