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 types.

In most massive mining operations, grade control programmes must be specified in terms of protocols that define sampling points and methods, appropriate for the method, from the creation of the grade/block model to the final product dispatch. Grade variability in such operations is often high, and this variability must be understood from various phases of delineation drilling. Sampling methods

Since mining in some cases is already at more than 2 km vertical depth (as at the Northam Platinum Mine), assuming material to that depth can all be mined is technically straightforward. Mining to greater depth will encounter high temperatures and serious rock stresses. However, mining of the Witwatersrand gold reefs has progressed to a depth of 4 km. Hence, mining of Bushveld reefs to
