In contrast a new grade control methodology (grade splitting) was proposed to alleviate blasthole sampling bias, utilising geological mapping and mineralogical logging, currently practised throughout Rio Tinto Pilbara operations, to estimate theoretical grades for each flitch from a single blast cone assay.

Abstract In some mining operations, one of the most important roles played by the geologist is the supervision of grade control In an open-pit operation, this involves the sampling of blast-hole cuttings produced by down-the-hole hammer drills and the classification of bench reserves into ore, low grade or waste material, or into various
