yep, 3po has the correct numbers...
mind you with the grades now that seem saleable the reserve numbers at PMM will go up, especially at Koolyanobbing. The cutoff grade if I remember rightly is 56%Fe. I would suggest now the cutoff grade should be much lower.
I also believe that the Cockatoo tonnage will grow a bit., perhaps another 10mt (100%).
Cheers, Tony.
