    Ivanhoe’s Platreef expansion: throughput, hoisting and cost lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Ivanhoe Mines’ Platreef project in Limpopo has completed construction of the 4‑Mtpa Shaft #3, broken ground on a 3.3‑Mtpa Phase 2 concentrator and started widening Shaft #2, keeping its Phase 2 expansion on schedule for end‑2027. Hoisting capacity is set to rise five‑fold to about 5 Mtpa, lifting output from roughly 100,000 oz to over 450,000 oz of PGMs plus gold, with a projected Phase 2 life‑of‑mine cash cost of $599/oz net of byproduct credits. A future Phase 3 could take throughput to 10.7 Mtpa and extend mine life by 29 years.

    Technical Brief

    • Shaft #3 is designed for 4 Mtpa hoisting, relieving current ore and waste constraints on Shaft #1.
    • Widening of Shaft #2 has commenced; once complete it will be Africa’s largest hoisting shaft.
    • Shaft #2 is scheduled to hoist labour and materials by end‑2028, and ore by end‑2029.
    • Phase 2 concentrator earthworks are underway, targeting completion of the 3.3‑Mtpa plant by end‑next‑year.
    • Ownership structure includes 26% held by a B‑BBEE group and 10% by the JOGMEC‑ITOCHU consortium.
    • The orebody averages 26 m of continuous, flat‑lying mineralisation, around 25 times thicker than incumbents.
    • Thick, flat geometry enables high mechanisation, directly supporting lower unit mining costs and improved safety conditions.
    • Preliminary economic assessment forecasts >1 Moz PGMs+Au per year plus ~22 kt Ni and 13 kt Cu after all expansions.

    Our Take

    Ivanhoe Mines features repeatedly in our recent coverage, from the Platreef Phase 2 concentrator HPGR contract with Weir (March 2026) to revised Kamoa-Kakula copper guidance (April 2026), signalling that Platreef’s platinum-group, nickel and copper output is being advanced in parallel with a broader portfolio reset.

    With a 35-year mine life post-Phase 2 and a further 29 years contemplated in Phase 3, Platreef in South Africa stands out in our database as one of the longer-life polymetallic assets, which typically underpins more aggressive downstream and offtake negotiations for platinum, palladium, rhodium and nickel than shorter-life PGM mines.

    The 26% B-BBEE and 10% JOGMEC-ITOCHU ownership stakes at Platreef give both domestic empowerment interests and Japanese buyers structural leverage over a low-cost, multi-decade PGM–nickel–copper supply source, which is strategically relevant given Ivanhoe’s concurrent critical-minerals positioning in projects like Kipushi under US-linked initiatives.

    Safeguarding conveyor performance: proactive maintenance lessons for mine engineers

    Safeguarding conveyor performance in mining and mineral processing, MATO Products sales engineer Keletso Mabula advocates comprehensive conveyor assessments focused on belt cleaners, carryback control and component wear. Proactive inspection of scraper alignment, blade tension, spillage patterns and chute loading conditions is positioned as essential to sustaining throughput and reducing unplanned stoppages on high‑tonnage overland and plant conveyors. The approach emphasises structured condition monitoring and timely maintenance interventions rather than reactive repairs once belt mistracking, excessive dust or material build-up have already escalated.

    MinRes Bald Hill lithium mine restart: contracting and planning notes for engineers

    Mineral Resources (MinRes) is restarting operations at its 100%-owned Bald Hill lithium mine in Western Australia after what it describes as a significant and sustained recovery in lithium prices. The restart follows several months of planning to re-establish safe operating procedures and production systems at the site, located about 50 km from Kambalda in the Eastern Goldfields. For mine planners and contractors, the move signals renewed demand for contract mining, crushing and haulage capacity tied to spodumene output in the region.

    UQ coarse particle processing program: design and retrofit insights for mine engineers

    The University of Queensland’s Collaborative Consortium for Coarse Particle Processing Research is entering a second five‑year phase to scale up coarse particle flotation technologies that allow recovery of particles up to several millimetres, reducing grinding energy and water use. Phase I delivered the JKHFmini laboratory rig and plant trials with Eriez HydroFloat and FLSmidth REFLUX Flotation Cell units on copper and gold ores, targeting coarser grind sizes than conventional circuits. The renewed program will expand pilot‑scale testing and integrated circuit modelling, with direct implications for comminution circuit design, tailings management and brownfield plant retrofits.
