    BHP battery truck static charging at Jimblebar: productivity lens for mine planners

    First reported on International Mining – News

    30 Second Briefing

    BHP is running battery-electric haul truck trials at the Jimblebar iron ore mine in the Pilbara using two Caterpillar 793 XE Early Learner units, in a joint programme with Caterpillar and Rio Tinto. The focus is on quantifying productivity impacts of static charging, including effects on haul cycle times, truck availability and fleet scheduling compared with diesel 793s. Outcomes will directly inform future pit design, charging bay layout and power infrastructure planning for large-scale BEV deployment on similar ultra-class truck fleets.

    Technical Brief

    • Trials use two Caterpillar 793 XE “Early Learner” battery-electric haul trucks at Jimblebar.

    Our Take

    The related 17 September item in our database notes BHP has already quantified about 1,000 fewer operating hours per battery truck per year under static charging, which at a high‑throughput iron ore hub like Jimblebar in the Pilbara likely forces a rethink of fleet size and standby capacity to keep tonnes moving.

    Among recent iron ore coverage, BHP and Rio Tinto feature heavily in Pilbara decarbonisation trials, so Caterpillar’s 793 XE Early Learners at Jimblebar will be closely watched as a benchmark for how quickly large OEM battery haulage can be made productivity‑neutral against diesel in large open pits.

    With over 1,200 mining stories and a strong cluster around ‘Projects’ and ‘Sustainability’, Jimblebar’s battery‑truck trial stands out as one of the few that explicitly weighs carbon gains against quantified productivity loss, giving other iron ore operators a rare data point for their own electrification trade‑off studies.

    Gold price slides on strong dollar: planning implications for mine projects

    Gold prices slipped to a one-week low as spot gold fell 0.4% to $4,271.16/oz in New York and December futures eased 0.3% to $4,306 amid a stronger US dollar and expectations of more hawkish US Federal Reserve rate moves. The dollar hit a two-month high and US 10-year Treasury yields hovered near a 20-year peak, sharply raising the opportunity cost of holding non-yielding bullion. Oil gained about 1% on stalled US–Iran talks over the war, while spot silver dropped 1.8% to $63.29/oz, platinum 0.2% to $1,746.44, and palladium rose 0.5% to $1,266.40.

    OceanaGold Waihi expansion: design, throughput and tailings notes for engineers

    OceanaGold is weighing a 50% expansion of its Waihi plant to 1.2 Mt/y after Wharekirauponga drilling returned standout intercepts including 6.3 m at 97.2 g/t Au from 481.5 m in the East Graben vein and 8.5 m at 41.5 g/t from 399 m. The move would enable concurrent feed from Martha Underground and Wharekirauponga post‑2032, building on a 2024 plan outlining 1.6 Moz over 15 years and an initial 4.1 Mt reserve at 9.2 g/t. Underground development is advancing, with the Waihi North decline now 350 m, first vent shaft under construction, staged commissioning of a new water treatment plant, and early works on a new tailings storage facility due in Q4.

    Kinross Gold output cut and higher AISC: operational drivers and FCF lens for mine teams

    Kinross Gold has cut its 2026–27 production outlook by about 8% to 1.84–1.86 million attributable gold-equivalent oz. a year and raised 2024 AISC guidance to $1,850–$1,900/oz after winter storms, copper-rich sulphide ore and poor recoveries at La Coipa in Chile, plus weaker mining rates, grades and recoveries at Round Mountain Phase S in Nevada. The company is stockpiling high-copper material, studying a new flotation circuit for deeper sulphide mineralisation that may overlie a copper porphyry system, and using a smaller shovel at Round Mountain to cut dilution. Despite the operational hit and a Q3 output cut to about 425,000 oz., Kinross has lifted its 2026 shareholder return target to 50% of free cash flow and has already returned about $800 million this year, mainly via $655 million in buybacks.
