14. Tops and Bottoms of Porphyry Deposits featuring Richard Sillitoe
Minerals - Discovery to RecoveryShow Notes
Richard Sillitoe and John Thompson talk about the evolution of the porphyry model from plate tectonics to lithocaps, mineral zoning, and the link to epithermal gold systems. How has the classic ‘tops and bottoms of porphyry deposits’ model changed and what have we learned over 50 years to guide our exploration. A prime example of the epithermal - porphyry connection is well known at the Lihir Gold Deposit, Papua New Guinea, operated by Newcrest Mining. We talk to Stephanie Sykora who studied...
