Guess who's in the hot seat this week! I'm very excited to have Ross Large joining us to share his insights on his Silver Bullet for Porphyry Copper Explorers!
Back in 2001 Ross developed a simple graphical method, called the Alteration Box Plot, to help interpret alteration assemblages in VMS deposits, based on whole rock multi-element analysis. Now that multi-element ICP-MS analysis of drill cores and RC chips has become very common there is the potential to apply this approach to porphyry copper alteration. Ross has spent the last 18 months thinking about the problem, and this talk is an outcome of his efforts. Because overprinting assemblages, and veining, in porphyry systems is very common, this task has proved to be a challenge. However, with the help of several porphyry experts, he thinks they have made some progress, which he welcomes you to apply this approach and give feed-back on its success or otherwise.
