MM Page 27: Reserves = 2,070 m Tonnes, Resources = 6,900 m Tonnes -- can see "The full Resource is 2,200tonnes"
BTW There is an interesting comment on page 29. "Only 2.5bn of the existing 6.9bn tonnes of JORC compliant resources will be required to support 30 Mtpa for > 30 years".
Which implies that at least (6.9 / 2.5) x 30 = 83 Million Tonnes per annum would be possible.
Or the reserve of 2,070 x 33.9% / 67.5% = 1,040 Billion Tonnes
Couuld be 1,040 BT x (6900/2500) = 2,870 Billion Tonnes (i.e. a bit lower that the 3,250 Billion from the resources due to higher confidence) had the entire site been drilled.
