Project outline

There is a significant amount of effort associated with understanding the genesis and evolution of copper-gold (Cu-Au) porphyry systems and their associated epithermal expressions, due to their commercial importance based on dual commodities. Consequently, this mineralisation is frequently well characterised at a regional and deposit scale. However, the strong association of critical elements such as Palladium (Pd), Selenium, (Se) or Tellurium (Te) in parts of the mineralised system is poorly understood.

This project aims to address questions of trace element mobility and concentration within evolving magmatic hydrothermal systems:

  1. What are the trace elemental signatures associated with magmatic hydrothermal gold mineralisation?
  2. What can they tell us about the evolving chemical environment during ore genesis?
  3. Which other (often critical) metals can be co-genetic with gold, and what are the controlling factors in their enrichment?
