Ann: Resource Increased To 0.5 Billion Tonnes , page-40

The primary low quality grade is beneficious to dso equivalent - about 63-67%. So with a fairly standard approach in terms of equipment and time, this 0.5 billion resource may be improved to a much higher grade, with a decrease in resource total. GBG is a case in point.

MPI has been the goal, though there is any number of options along the way to part fund this operation. Selling tonnage of dso equivalent may be one such way.
