    Ivanhoe’s Platreef Shaft #3 milestones: hoisting and plant scale-up for mine planners

    April 28, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    Ivanhoe Mines has completed construction of the 4 Mt/y Shaft #3 at its Platreef Mine in Limpopo, South Africa, providing a key hoisting and ventilation asset for the ultra-deep, bulk-scale PGM-nickel-copper operation. Ground has also been broken for the Phase 2 concentrator, which will expand processing capacity beyond the initial 770,000 t/y plant now under construction. Widening of Shaft #2 has commenced to increase hoisting capacity and improve access for large-scale underground mining equipment.

    Technical Brief

    • Co-location of hoisting and ventilation in Shaft #3 simplifies underground layout but increases shaft-criticality for operations.
    • Progressive widening of an existing deep shaft implies staged ground support upgrades and revised shaft lining design.
    • Sequencing concentrator expansion with shaft upgrades allows ramp-up without major interruption to early ore handling.

    Our Take

    Our database shows Platreef as one of the few South African projects combining platinum‑group metals with battery metals such as nickel and lithium‑linked spodumene, which positions Ivanhoe Mines to hedge against single‑commodity price swings once Shaft #3’s 4‑Mt/y capacity is fully utilised.

    With Ivanhoe Mines simultaneously cutting near‑term copper guidance at Kamoa‑Kakula, the steady advancement of Platreef in South Africa signals a deliberate portfolio balance between Congolese copper exposure and multi‑metal production from a more established mining jurisdiction.

    Hexagon’s Ore to Value vision: material flow intelligence for mine planners

    Hexagon’s Mining division is expanding its 2021 “Power of One” life-of-mine platform into an “Ore to Value” vision that links fleet management, drill and blast, mine planning and plant control through a single data environment. The approach centres on material flow intelligence, using connected sensors, infield apps and cloud-based analytics to track ore parcels from block model to mill and final product in near real time. For engineers, this promises tighter reconciliation, more accurate ore routing and faster feedback loops between geology, operations and processing.

    BHP and Rio Tinto back WA regional growth: workforce planning lens for mines

    More than $569 million is being directed into regional Western Australia under the State Government’s Seven Cities Vision, with BHP and Rio Tinto jointly committing $150 million for new homes and worker accommodation. The funding targets housing supply and liveability in key mining centres, aiming to ease labour constraints that have driven high FIFO reliance and wage pressure across the Pilbara and other hubs. For mine planners and project teams, improved local accommodation capacity could materially affect workforce availability, roster design and long‑term expansion decisions.

    Nolans rare earths funding: execution and offtake risk notes for mine planners

    Arafura Rare Earths has moved its Nolans rare earths project in the Northern Territory closer to construction by firming up project funding while keeping a “deliberate and considered” pace on additional offtake deals. The NdPr-focused project, located about 135km north of Alice Springs, already has cornerstone offtake agreements with automotive OEMs including Hyundai and Kia for magnet rare earths. The funding progress reduces execution risk for mine, concentrator and hydromet plant development, but Arafura is signalling it will not trade pricing or contract flexibility for rapid offtake volume.
