Ann: A4 Dome Potential to Support T3 Expansion Strategy, page-19

So back of the envelope estimate again .
10 * 2.7 * 800*4200 = 90.7 million tonne of ore .
The density at 2.7 was only a guess , probably too low .
So yes about right for 100 Million tonne of ore .

Looks like a good mine .Let's hope we can find something like it .

I don't know anything about mining and cannot quite understand the mining technique .
If it caved in wouldn't they have to bog it out before the could get back to the mining face ?
