The comminution test work included semi-autogenous grind mill comminution on the new drill core, Bond rod mill work index, Bond ball mill work index and abrasion index tests. The results indicate the material is hard with results ranging from 11.8 -24.6 kWh/t and the 75 th percentile of the samples tested was 21.1 kWh/t for the variability samples.
