Primary and secondary high-grade gold mineralisation processes in orogenic systems: key to a sustainable mining?

Project Summary

This project is working to deliver new constraint on the reservoirs and transport processes responsible for the deposition and enrichment of gold in high-grade ore systems through a combination of case study analysis and experimental investigation of gold mineralisation.

Despite their significance to Western Australia and long history of development, the physical processes leading to the development of high-grade orogenic gold systems remain poorly understood.

By delivering a more robust and comprehensive mechanistic framework for the development of these high-value, low-volume gold systems, this project will deliver improvements in exploration targeting, resource estimation and hydrometallurgical processing of gold ore systems.
