    It was found that the lead collection fire assaying method, which is widely used in South Africa for this purpose, is not robust to the complex form of PGE mineral host occurrence in this ore type. Mill feed and tailings both show a potential for underestimation of grade, whilst concentrate shows a potential for overstatement of grade.
