    Abstract In some mining operations, one of the most important roles played by the geologist is the supervision of grade control In an openpit operation, this involves the sampling of blasthole cuttings produced by downthehole hammer drills and the classification of bench reserves into ore, low grade or waste material, or into various metallurgical typesGrade Control, together with operational management and mine planning ensures that the qualities of the blocks planned for mining and the material being mined meet the stringent process requirements of the refinery, in terms of zinc grade, gangue acid consumption and deleterious elements that may impact on the efficiency and costs of the metallurgical process 3 THE GRADE CONTROL PROCESS AGRADE CONTROL BLENDING AND SELECTIVITY FOR OPTIMALGrade control Grade control A large Copper open pit mine in Chile has lost US$134 million over a 10year period because of suboptimal grade control procedures based on the blast holes sampling It was estimated by the difference between actually used blast hole sampling protocol and its optimized versionOptimisation grade control procedures at the open pit
