years ago DRN had 5 sites at upper beta creek which had the richest diamond mining potential in Australia after the argyle mine (worlds biggest diamond mine site).they entered into an agreement with BHP to mine it and since then I haven't seen anything about it.Does anyone out there know what's going on.I believe BHP have locked it up until the argyle mine runs out of production which could be many many years away.
