Results from testwork on low-grade ore from the project returned overall gold recovery of 97.2% and an increase to the mill feed grade of 1.5 times the stockpiled grade, while 33% of the mass was rejected at 0.2 grams per tonne gold.

The company said the work was extremely effective at rejecting the hangingwall dilution that will be incurred during mining of the Woodley’s Shear, the main ore-hosting structure.

In the May 2017 prefeasibility study, dilution averaged 43%, the bulk of which came from the ultramafic hangingwall.

The ore-sorter has the potential to eliminate the dilution and boost underground mining rates by up to 34% without the need to increase the proposed size of the plant.
