    Yilgarn Iron–Thiess Koolyanobbing restart: mining and logistics notes for engineers

    Yilgarn Iron–Thiess Koolyanobbing restart: mining and logistics notes for engineers

    First reported on Australian Mining

    30 Second Briefing

    Yilgarn Iron has appointed Thiess to restart iron ore production at the Koolyanobbing operations in Western Australia’s Yilgarn region, reviving a site that previously supplied lump and fines to export markets via the Esperance port rail corridor. Thiess is expected to provide contract mining services including drill-and-blast, load-and-haul and ore handling, with a focus on quickly re-establishing pit access, waste stripping and ROM stockpile capacity. The partnership signals renewed demand for mid-grade hematite from smaller Yilgarn deposits, with implications for local rail logistics and port throughput planning.

    Technical Brief

    • For similar brownfield iron ore restarts, contract mining models like this reduce upfront owner capex exposure.

    Our Take

    Thiess’ recent win at Koolyanobbing sits alongside its new Sunday Creek underground contract in Victoria, signalling that the contractor is actively rebuilding a diversified Australian book across both iron ore and hard‑rock metals rather than leaning on a single commodity cycle.

    With Thiess concurrently trialling FLANDERS hybrid diesel‑electric haul trucks and participating in autonomous haulage tests at Mulgarrie, the Koolyanobbing iron ore restart gives it another Western Australian platform where low‑emission or automation initiatives could later be deployed at scale.

    Iron ore is one of the more frequently covered commodities in our mining database, and Yilgarn Iron’s move to restart Koolyanobbing via a contract miner suggests smaller owners are favouring outsourced operational models to stay flexible against price volatility and WA labour cost pressures.

    Kinross Tasiast Hitachi EX8000-6: design and planning notes for open pit teams

    Kinross Tasiast has commissioned a Hitachi EX8000-6 face-shovel excavator, now the largest mining excavator operating in Mauritania and only the fourth EX8000 unit delivered in Africa. The machine, weighing over 800 t and typically paired with ultra-class haul trucks, is expected to materially increase loading rates in the Tasiast open pit. For mine planners and geotechnical teams, the larger bench heights, wider dig faces and higher instantaneous production rates will influence slope design, traffic management and blast fragmentation requirements.

    Hillhead 2026 at Hillhead Quarry: key equipment takeaways for engineers

    Hillhead 2026 at Hillhead Quarry from 23–25 June will host 600 exhibitors with expanded live demonstrations of crushers, dumpers, tyres, powertrains, hydraulics, and safety systems for quarrying, construction, and recycling. Key launches include Pilot Crushtec’s TwisterTrac VS350E VSI crusher with Stage V Volvo Penta engine claiming up to 40% lower fuel use, Thwaites’ nine-tonne ROPS+ dumper and new electric two- and three-tonne swivel models, and Continental’s LD-Master Rock L5 and MPT 91 tyres with integrated pressure/temperature sensors. Engineers can also assess ACE Plant’s Dromone D80 Ball & Spoon hitch for reduced whole-body vibration, Hyundai G2/DX engines via Marshall’s, and Jihostroj QHDM2 reversible hydraulic motors for mobile crushing plant.

    Jinbi Solar–Rio Tinto PPA: grid integration and offtake lessons for mine engineers

    Yindjibarndi Energy Corporation has reached financial close on the Jinbi Solar Project in Western Australia’s Pilbara and signed a 30‑year power purchase agreement with Rio Tinto to supply renewable electricity to the miner’s operations on Yindjibarndi Ngurra. The Indigenous-led project will now move into construction, adding large-scale solar generation into Rio Tinto’s Pilbara grid, which is currently dominated by gas and diesel. For miners and project engineers, the deal signals growing long-horizon offtake certainty for utility-scale renewables integrated with remote, heavy-industry loads.
