The company said in a recent statement that plant commissioning and material trials had commenced and that it was expected to take up to four weeks to com- plete trials and optimise programming for various ore types and grade profiles. Observations from the first trials indicate beneficiation on the jig beds is extremely efficient and both product grade and yield exceeded expectations. Trial mining at the three Labusrus pits to a depth of 5 m as planned has been completed and the material intended for beneficiation through the new plant has been stockpiled.
