A rapid automated search method, developed for the location of native gold grains in polished sections with a scanning electron microscope (SEM), has been extended to locate platinum group elements (PGE), in particular platinum and palladium, and their minerals down to 1 ¦m in size. Problems associated with the search for PGE minerals are discussed and examples of PGE minerals located with the facility in drill core sections, crushed ores, and metallurgical test products are given.
