Choseright, have you actually looked at the individual drill hole reports, rather than just accepting the reported overall average? If so, you will be aware that the 11% average includes all the richer ore in the Mutola zone (15%), and also be aware that the grades either side of it are substantially less (which is pretty obvious, to get down to an 11% average). Just go through the drill hole data which is already available, and you will understand. Don't be put off by the fact that there are a few pages of figures in the three or four relevant reports, it's all there.

Open pits are neither fanciful nor complex. If you think you can dig the ore out another way, please tell us how.
