Mining automation and electrification have long been more than just demonstration projects. Rio Tinto operates over 300 autonomous trucks in Pilbara; BHP has deployed 33 autonomous trucks and 11 autonomous drills at Escondida Norte; Anglo American manages 30 automated (remotely operated) trucks at Quellaveco via a remote operations center; and Fortescue has signed a $2.8 billion deal for 475 units of equipment, including about 360 battery-electric, autonomous-ready trucks. Currently, the vast majority of the hundreds of autonomous trucks at Rio Tinto, BHP, and Anglo American are still diesel-powered. Fortescue is the only one to have placed a large battery-electric order so far (about 360 T264 units). Globally, battery-electric trucks at Rio Tinto and BHP are still only in single-digit testing, and Rio Tinto's AutoHaul is an autonomous train, not a truck AHS. These projects show that top miners have moved technology from trials into core production. The core reason they are investing heavily is not just chasing the "smart mine" concept, but because new mines are becoming increasingly expensive and slow to bring online. Compared to waiting for new mines, improving the uptime, haulage efficiency, and safety stability of existing mines is faster and more controllable. Why Are Miners Willing to Invest? 1. Declining grades mean that to maintain the same mt Cu, miners need to move more ore IEA data shows that the average global copper ore grade has declined by 40% since 1991, and the capital intensity of brownfield expansions has risen by 65% since 2020. If grades halve, producing the same mt Cu as in previous years would require moving twice as much ore, doubling the workload in every step of mining, hauling, and processing. The lower the grade, the more valuable equipment efficiency becomes, making automation increasingly cost-effective. 2. Top miners have the conditions to spread
