In the latest episode of the Altitude Minerals Podcast, Managing Director Duncan Chessell is in conversation with world-leading geochemist and in-house porphyry expert Professor Bruce Schaefer to explore these elusive and valuable mineral systems, which account for roughly three-quarters of the world’s copper and a fifth of its gold.
This episode unpacks how they form and the geophysical and geochemical tools explorers use to find them. The conversation also takes a closer look at the Byrock and Theseus projects in NSW and what the next round of drilling aims to reveal.
