Dive deep into a mega-magmatic mineral system — the Bushveld Complex with host Maxwell Porter. Max is joined by Professor Wolfgang Maier and Dr. Erin Thompson who share their insights on the geological setting, economic significance, and evolving scientific understanding of this world-class mineral province.

Wolfgang Maier discusses the Bushveld Complex’s geological framework, its importance in today’s resource landscape, and the controversies surrounding models for its genesis — and how these models have shifted over time. Wolfgang Maier completed his PhD on the Bushveld at Rhodes University, South Africa in 1992. He taught igneous petrology and economic geology at the Universities of Port Elizabeth, Pretoria (South Africa), Chicoutimi (Canada), UWA (Perth, Australia) and Oulu (Finland). He is now Professor for Ore Geology at Cardiff University, UK. Wolf’s research deals with petrological and geochemical processes in mafic-ultramafic igneous systems that contribute to our understanding of continental magmatism, mantle evolution, plate tectonics and the formation of magmatic ore deposits including PGE, Ni-Cu, Cr, and V-Ti-Fe deposits. 

Erin Thompson shares what drew her to study the northern limb, why it holds both geological and economic importance, and how magmatic architecture and mineralisation controls shape exploration strategies. She explains the once-overlooked yet powerful tool of Niggli numbers, and how geochemistry and isotope studies inform exploration and the future of the Northern Limb. Dr Erin Thompson has recently completed her PhD at the University of Leicester, which focused on constraining the magmatic controls on Ni-Cu-PGE mineralisation in the world-class Platreef deposit, northern limb of the Bushveld Complex. Her research was funded by Anglo American as part of the Northern Limb in 4D (NL4D) research consortium, which included researchers from across the UK at the University of Leicester, Cardiff University and Camborne School of Mines. She is now applying her background in magmatic processes and geochemistry in her new role as an exploration geologist.
