Blasting costs
Even though drill and blast costs in the ore have increased, the overall net benefit to Mt Rawdon, including mining and processing costs, is expected to be more than $5 million. While the Vistis system is a key input to the mine to mill program the benefits Mt Rawdon achieved are equally attributable to the operational changes it made.
