The Carosue Dam Au deposit is located in the Eastern Goldfields of Western Australia. Gold is hosted by volcaniclastic units and is spatially associated with monzonitic intrusions and an alteration style similar to alkalic porphyry deposits. A test program was implemented to evaluate the geometallurgical characteristics of drill core intervals. Physical test work using constrained crushing and sizing conditions allowed the geometallurgical attributes to be correlated to the measured Au fractionation response in high- and low-grade domains. Final reporting is due in 2019.
