Drones aren’t just for airplanes and helicopters: British-Australian mining giant Rio Tinto is switching exclusively to remote-operated trucks at two major iron-ore mines in western Australia’s remote Pilbara region.

The Yandicoogina and Nammuldi mines started using drone trucks to move all of their iron ore from their pits starting today (Oct. 19), according to Australia’s ABC News. The trucks will be remotely operated by workers at a center in Perth, some 1,200 kilometers (750 miles) away. The driverless truck system is designed to eliminate dangerous jobs while also cutting costs.

Rio Tinto also operates a fleet of drone aircraft to monitor sites and equipment:
