Ann: Development Progress - Lindi Jumbo Mine, page-4721

When it comes to the process plant they have been concentrating on throughput which is fair enough. The next step will be to look at recovery, purity and flake size distribution but I can see that proving difficult due to the lack of understanding of what the grade and flake distribution is of the stockpile on the ROM. Do they know what the grade is based on clise spaced grade control drilling or are they guessing based on a few grab samples? Perhaps theywill just assume reserve grade? I would argue that the critical next step of optimising plant performance requures high confidence in the grade of what you are feeding it. I do hope they have a regular conveyor belt sampling regime with quick turnaround of assays.
