Working with Bruker AXS (Brisbane) this project evaluated the use of rapid micro-XRF analysis of drill core samples for applications related to geometallurgical characterisation and development of predictive grade-by-size indices. Sample material from porphyry copper systems was analysed using a Bruker M4 Tornado with AMICS for mineralogical mapping and textural assessment of ore and gangue phases to evaluate pre-breakage geological/geometallurgical controls on grade-by-size fractionation.

Development work has been completed with validation using MLA and whole-rock mineralogical techniques. Final reporting and research outputs will be delivered in 2018.
