Global Platinum-Group Resources Estimated at More than 150K Metric Tons
The first-ever inventory and geological assessment of known and undiscovered platinum-group element (PGE) resources estimates that more than 150,000 metric tons of PGEs may exist in the two southern African countries that produce most of the global supply of these critical elements.
The USGS study identifies 78K metric tons of known PGE resources in South Africa and Zimbabwe and estimates 75K metric tons in PGE resources that may be present, but are undiscovered. This is more than 20 times the total tonnage produced since the 1920s when PGE mining began in these countries. (more…)
