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 metallurgical types.
