menaced,
I assume Harmony did the initial feasibility but I would like to know that they had done the best job at the time given the gold price and available drilling results. I wouldn't want DIO to blindly accept their study in order to interpret a bigger pit design especially after the problems they had with pit wall failure. I mean, was that just a very unlucky incident or was it because Harmony/DIO hadn't done their numbers properly? You see what I mean.
Dont get me wrong, I think it sounds a great idea but I would like to know they arent taking short cuts......
