Komatsu's FrontRunner Autonomous Haulage System was born at a copper mine in 2008 — CODELCO's Gabriela Mistral operation in Chile, the world's first commercial AHS deployment. For most of the next 18 years, the technology found its deepest commercial penetration in iron ore. Now, with a fleet of 19 Komatsu 930E ultra-class haul trucks operating driverlessly at Vale Base Metals' Salobo Copper Complex in Pará, Brazil, autonomous haulage is returning to the commodity that created it — this time at a scale that the energy-transition copper supply crunch demands. The Salobo go-live, reported by International Mining on August 17, 2026, did not arrive in isolation. The week before, Vale Base Metals announced it is proceeding with a Coarse Particle Flotation expansion at the Salobo III plant — a $215 million project expected to add 6 million tonnes of annual ore processing capacity and up to approximately 30,000 tonnes of additional copper production per year. And since July 2026, Salobo's track dozers have surpassed 5,000 operating hours under Hexagon's TeleOp remote-control system, keeping operators away from the active mining face. Three technology layers — autonomous haulage, remote dozer operation, and next-generation flotation — are now operating simultaneously at a single copper complex, forming something genuinely new in the industry: an integrated copper mine automation stack. Why Copper Mines Are Going Autonomous Now The copper supply picture is the fundamental driver. The International Energy Agency's Global Critical Minerals Outlook 2026, published in July, projects that current mine-project pipelines will leave a supply gap of approximately 25 percent by 2035 — slightly narrowed from a 30 percent shortfall projected in the 2025 edition, but still structurally significant. Demand is being driven by electric vehicles, power grid modernization, and AI data centers, which IEA projections estimate could require 250 to 550 kilotonnes of copper
