emphasis on sampling

Worth remembering that "the Luderitz ML111 sampling programme is focused on recovering diamonds from gridded sample sites at sufficient density for estimation of JORC-compliant resources to at least Indicated status. Bonaparte will then retain a 30% interest in the net profits derived from mining of the defined resource by DFI."

My take on that is, if it's commercial, sit back and count the lolly while DFI do the hard yards!
