Let's suppose a delegation of local bankers are on a site visit to Lindi as part of due diligence for a bank overdraft. They are aware that Gemcorp have security over the assets so they are particularly concerned with the plant performance. Realizing that plant performance has everything to do with what you feed it, they ask about the ROM stockpile. When told it is estimated to be 19,000 tonnes at 22.5 percent TGC they are impressed until they ask how the grade was calculated. When told the grade is based on 5 grab samples they probably head back to the carpark wondering why they bothered.
