We have collected and analysed grade information for nine metals: copper, gold, iron, lead, manganese, nickel, PGM, tin, and zinc. Based on this analysis, we have developed a proposal of "grade classes", i.e., what could be considered low-grade, average-grade, and high-grade deposits for all these metals. We discuss the implications of possible developments into …
