sp going to fall due to ann, page-22

For my two cents worth, I think this is a reasonable start. They will probably end up getting some results that are better and some that are not, but don't get too hung up on grade, as it is the cost of con on the ship that counts (and the price received).

contraindicator - the maiden resource is 277Mt @ 26%. If we have 100% conversion to reserve and there are no mining losses (to keep the calc simple) and assuming 65% iron con, we have 26% / 65% x 277Mt = 110Mt of con at 65% iron. 110Mt / 10Mtpa = 11 years.
