This study summarizes the identified mineral inventory of PGE in South Africa and Zimbabwe and estimates the potential amount of undiscovered PGE resources that may be present in these countries.

This study delineated permissive areas for undiscovered porphyry copper deposits, compiled a database of known deposits and significant prospects, estimated undiscovered deposits within those areas and made probabilistic estimates of their metal content.
