Logs need to resemble WMT and I know for a fact part of the holdup was due to wetness and samples needed to be dried.
I think by memory the WMT for a JORCed Wet tropical laterite product is 8-14%
Crickey's !! 50% moisture levels seems quite high. End users would want to be buying a resource not water. If that's the case use a density calc of 3. Slurry.
IMHO
