    BHP & Rio Cat BEV truck trials in the Pilbara: haulage and power notes for engineers

    First reported on International Mining – News

    30 Second Briefing

    Australia’s first Cat 793 XE Early Learner battery-electric haul trucks have arrived at BHP’s Jimblebar iron ore mine in the Pilbara, where BHP and Rio Tinto will jointly test Caterpillar’s BEV heavy haulage platform under production conditions. The two 220‑t class trucks, supplied under an industry‑first shared development agreement, will be evaluated on typical Pilbara duty cycles, ramp profiles and ambient temperatures. Data from Jimblebar will feed into Caterpillar’s commercial 793 BEV design, with direct implications for trolley, charging and pit power infrastructure planning across large open pits.

    Technical Brief

    • Outcomes are expected to influence future diesel displacement roadmaps across large Australian mining truck fleets.

    Our Take

    BHP and Rio Tinto are two of the most frequently appearing majors in our 180 Mining stories, so Pilbara iron ore decarbonisation moves like these BEV truck trials are likely to set informal benchmarks for other bulk operators considering fleet renewal.

    Running Caterpillar’s Early Learner battery-electric trucks at Jimblebar gives BHP and Rio Tinto early operational data they can leverage in future procurement negotiations, especially as BHP is simultaneously pursuing large-scale growth options such as its proposed Anglo American combination in other coverage.

    With iron ore a recurring keyword in our database and Pilbara assets central to both BHP and Rio Tinto, proving BEV haulage at this scale will be closely watched by regulators and investors as a test case for how quickly high-tonnage Australian operations can cut diesel exposure without compromising productivity.

    Suncor Cat AHS at Mildred Lake and Komatsu Mud Mode: integration notes for mine planners

    Suncor has commissioned its first Autonomous Operating Zone at Syncrude’s Mildred Lake oil sands mine, extending its autonomous haulage system deployment beyond the existing fleet of about 140 autonomous trucks already running at other Suncor sites. The new zone uses Cat AHS fleets under Suncor control (since late 2021) and is complemented by Komatsu AHS trucks at Base Plant operating with a dedicated “Mud Mode” to maintain traction and control in soft ground. For mine planners, this signals wider-scale AHS integration across multiple pits and variable ground conditions.

    Central Nevada Gold’s Mule Canyon acquisition: project and risk lens for engineers

    Central Nevada Gold has completed a US$20 million acquisition of Newmont’s past‑producing Mule Canyon mine in Nevada, targeting a prefeasibility study and key permits in H2 2027 ahead of a potential 2028 construction decision. Mule Canyon previously produced about 500,000 oz gold at an average head grade of 3.8 g/t with ~94% metallurgical recovery, and comes with a database of 2,149 drill holes totalling over 335,000 metres across six mineralised zones over 2.5 km. The company plans an IPO as early as 2027 after a 20‑hole metallurgical and infill drilling programme to upgrade inferred resources and de‑risk the project.

    Greenland Mines’ Sarfartoq licence: key project and offtake notes for mine planners

    Greenland Mines has secured government approval under the Greenland Mineral Activities Act for the indirect transfer of the Sarfartoq carbonatite complex exploration licence, clearing a key condition in its US$35 million acquisition from Neo Performance Materials, which retains offtake rights to up to 60% of future ore or concentrate. The Nd-Pr-enriched project, about 60 km from Kangerlussuaq, carries a historic NI 43-101 resource with 5.88 Mt indicated at 1.77% TREO and 2.46 Mt inferred at 1.59% TREO, based on 23,000 m of drilling. The news sent Greenland Mines’ NASDAQ-listed shares up more than 22%, giving the company a market capitalisation of US$31.4 million.
