Iron oxide copper-gold deposits: Geochemistry and Geometallurgy (2022 - 2024)$643,333
Description
Demand for Cu continues to increase as governments and corporations around the world increasingly invest in non-carbon-based forms of energy and transportation, such as wind turbines and electric vehicles. This places greater pressure on mining companies to find new Tier 1 resources. Mining companies that explore for Cu and other base or precious metals are increasing spending on deeper drilling campaigns targeted by ever more sophisticated geochemical, geophysical, and geostatistical techniques. However, new discoveries of Tier 1 Cu resources are occurring less frequently today than in previous generations, and the increase in exploration expenditure has not led to a direct increase in the number of discoveries (Fig. 1).

Building capacity in Regional Australia to enhance Australias Economy through research, training, and environmentally sustainable production of critical metals (2022 - 2024)$3,537,047
Description
This research project involves collaboration between STEM and Social Science researchers at the University of Tasmania (UTAS) and academic, industry, and government partners. Through its three research Elements, the project will provide novel tools for characterisation of critical metals deportment, optimise methods, and devise new workflows for critical metals processing, develop new waste management strategies, and deliver innovative community education, training, and outreach strategies that build a local, skilled jobs-ready local workforce for regional industry.

Predictive geometallurgy controls on grade by size (2016 - 2021)$1,600,000
Description
Grade by size fractionation has been recognised in a number of deposits. The challenge is to recognise what aspects of ore mineralogy and texture lead to the development of significant grade by size fractionation. A predictive understanding of this process will significantly aid the recognition of suitable rock masses for grade engineering.The aim is to produce a predictive model for grade by size fractionation that reaches TRL 4.

Ore Characterisation at the Productora deposit, Chile (2014 - 2016)$122,660
Description
The Productura deposit is a pre-feasibility IOCG-style breccia hosted Cu-Au-Mo deposit located in Chile. The aims of this PhD project are to investigate relationships between alteration patterns and ore textures at the Productora deposit, particularly in the transitional ore zone, which may impact on liberation behaviour and flotation response. It will develop quantitative and predictive geometallurgical models through characterisation of the ore(s) and altered rocks at Productora in order to facilitate modelling and prediction of processing behaviour. The emphasis will be on understanding mineralogical and geochemical zonation patterns and their relationship with geometallurgical characteristics of the ores, including mineral texture and physical properties related to processing behaviour. Research techniques will include drill core logging and high resolution imaging, automated optical microscopy, mineral liberation analysis (MLA), LA-ICPMS analysis and ore genesis/geochemical techniques as required.

Sensor based sorting technologies for waste dumps and stockpiles associated with bulk mining (2014)$60,981
Description
This project seeks to understand the opportunities and implications of adapting sensing technologies for improved mineralised waste characterisation and management in the context of integrated Grade Engineering. This could include direct detection of deleterious components such as acid rock drainage, or detection of sub-parcels of higher grade material which could be re-assigned to processing. Research deliverables will be an assessment of opportunity for future application of emerging sensing and sorting technologies in the context of Waste Engineering, involving collaboration between CSIRO and CRC ORE research and industry participants. This will take the form of a final report and workshop with recommendations.
