Ann: Nachu Graphite Bankable Feasibility Study Finalised, page-119

Sorry to burst your bubble but your distribution table whilst correct for the DFS, it doesn't correlate with the "Graphite flake size and concentrate grades" table on page 14 of the BFS.
You have the correct percentages for super jumbo and jumbo but the rest differs from the BFS table. Instead of 32% large flake, the BFS states 25%. Medium is 10% instead of 9%. Fine correlates correctly at 18% and amorphous, which isn't even mentioned in the PFS comes in at 6%. It is the flake distribution that matters when calculating basket price not concentrate grades.
