Hi 10mc, to answer that one, one only needs to read what MNS has announced re the not financially sensible nature of the Nachu graphite project
"During the various phases of development of Nachu, the Company management conducted several studies looking at the viability of the export of graphite concentrate. Particular attention was focused on what impact would be on the flake graphite market if several other large scale graphite projects commenced operation. Magnis’ view was that the potential lower revenue pricing in the market would make any strategy or operation reliant on solely producing graphite concentrate would not be a financially sensible option"
