The unprocessed ore will be conditioned using water to minimise the dust generation prior to feeding. The conditioned ore will then be fed by frontend loaders and directed to the Ore bin apron via a 40m long by 15m wide ramp which has a 10 gradient. After the ore being processed, final products will be transferred to stockpiles via two 600mm
