Newmarket Gold has designed their own drone to inspect open stopes for misfires and to map the surrounding walls inside a mine. Ion Hann, Mine Manager of the Fosterville Gold Mine, said that the mine had already been built and developed last year and is providing remarkable advances in mining today. They hope to reach the stage where drones enter the mining industry as a standard for emergency responses, which includes search and rescue scenarios underground. There are numerous possibilities of this type of technology being introduced in the mining

industry. It can be used to aid with operator training during field work, where a live feed can be sent to the trainer while operator plans a heading. Hann commented that their ultimate goal is to get the drones into an autonomous state so the risks of site inspections and re-entries would lessen as operators would be able to do it on the surface.
