Good discussion – One of the key points I was trying to make is that other block cave mines use a very low cut-off, due to the low operating costs. NCMs Cadia East is another example, with a reserve of 1.2 Bt @ .3%Cu and 0.6 g/t Au. So if block caving can be sured up at Big C, the current resource 0.87 Bt @ .7% Cu and 0.3 g/tAu (0.3% CuEq cut-off) could potentially support a large (15 to 25 Mtpa) operation with a very long mine life.

Anyways, we probably won’t know to much more about Big C until 2014/2015.
