Assuming that the units in the Announcement have been reversed and at a swell factor of 1.3, the 195.6klcm becomes something like 150.5kbcm insitu. Subtracting that from 187.9kbcm in the pit leaves 374kbcm of potential ore which, at a bulk density for oxide sedimentary material of 2.3 is around 860kt. No mention has been made of dilution or reblocking of the model to an SMU for optimisation purposes to model dilution. Nor has grade (diluted or otherwise) or met recovery been mentioned.
