Terra Metals has made a significant high-grade discovery at Southwest. This workup does not attempt to value it, since the project has no economic study and no Southwest resource, but assesses whether the discovery is substantive and what evidence will confirm it.

South Africa holds about four fifths of the world's platinum group metal reserves. Samso looks at what Bengwenyama's chrome, its missing offtake and its unexplained discount are actually worth.

Southern Palladium has spent four years turning a shallow reef on South Africa's Eastern Limb into a mining right, an ore reserve and a metallurgical result that has changed what the project is worth. Chalice Mining has spent six years and much more money working towards something similar in Western Australia. Terra Metals has a discovery the market likes and no resource behind it yet. This piece asks one question. What does a platinum group element project need before it get

A handful of the world's giant copper mines also carry platinum and palladium. They are rarely worth mining on their own — but the story of how they got there is one of the clearest windows we have into how a copper-gold deposit is made. This is that story, told for the curious rather than the credentialled.
