    MinRes Bald Hill lithium restart: ramp‑up, output and JV lens for mine planners

    MinRes Bald Hill lithium restart: ramp‑up, output and JV lens for mine planners

    First reported on MINING.com

    30 Second Briefing

    Mineral Resources is restarting the Bald Hill lithium mine in Western Australia after an 18‑month shutdown, bringing back a 58 Mt resource grading 0.9% Li₂O and nameplate output of 165,000 dmt per year of 5.1% spodumene concentrate (about 140,000 dmt SC6 equivalent). Ramp‑up will see crushing and mining restart next month, first concentrate in July, first shipment via the Port of Esperance in Q1 FY2027 and full capacity in Q2. Once online, MinRes will be the only operator running three hard‑rock lithium mines with on‑site concentrate plants, alongside Wodgina and Mt Marion.

    Technical Brief

    • Bald Hill restart follows an 18‑month care-and-maintenance period initiated in November 2024 to preserve capital.
    • Site lies ~50 km south-east of Kambalda in Western Australia’s Goldfields, influencing logistics and workforce sourcing.
    • Operation is being brought online under a detailed restart plan focused on safe ramp-up after the extended shutdown.
    • MinRes attributes the decision to a “significant and sustained” lithium price recovery, with carbonate prices up >50% year-to-date.
    • Supply uncertainty from China’s mine suspensions and Zimbabwe’s raw export ban forms part of the restart market rationale.
    • MinRes market capitalisation sits at about A$12.7 billion, framing balance-sheet capacity for restart capex and ramp-up costs.

    Our Take

    Mineral Resources’ restart of Bald Hill adds another lithium stream to a portfolio that already includes 50:50 JVs at Wodgina with Albemarle and Mt Marion with Ganfeng Lithium, signalling a deliberate spread of spodumene and downstream exposure across multiple partners and ore bodies in Western Australia.

    In our database, MinRes’ recent coverage has been dominated by the Onslow Iron ramp-up and debt reduction, so bringing a 58 Mt, 0.9% Li2O asset back online suggests the balance of capital and operating focus is tilting back toward higher-margin battery minerals as lithium carbonate prices rebound.

    With first Bald Hill shipments only expected in Q1 FY2027, MinRes’ timing effectively staggers new spodumene supply behind current price spikes, which may help avoid locking in long-term contracts at the bottom of the cycle while still positioning the company to capture medium-term lithium demand growth.

    Sandvik underground fleet at Kamoa-Kakula: haulage and maintenance lens for engineers

    Sandvik has secured an order from Kamoa Copper SA for 19 Toro® underground trucks and loaders for the Kamoa-Kakula Copper Complex in the Democratic Republic of the Congo, taking the site’s Sandvik underground fleet to more than 100 units. The equipment will support one of the world’s largest underground Sandvik fleets at a single mine, operated by the Ivanhoe Mines–Zijin Mining joint venture. For engineers, the scale signals sustained high-volume, trackless underground haulage and significant long-term demand for OEM parts, maintenance capacity, and fleet management systems.

    Metso Durarok™ primary sizer at Yenipazar mine: design and throughput notes for engineers

    Metso has secured a €25 million order from Aldridge Mineral Madencilik A.Ş., part of CVK Mining, to supply key minerals processing equipment for the Yenipazar polymetallic mine in Türkiye, including one of its first Durarok™ primary sizers. The package, booked in Metso’s Minerals segment for 2026, will support primary crushing and downstream processing for a deposit containing multiple base and precious metals. For engineers, early adoption of the Durarok™ sizer at Yenipazar will be a reference case for hard-rock primary sizing performance in Turkish conditions.

    Volvo Autona / earth autonomous haulage: key takeaways for mine planners

    Volvo Autonomous Solutions has launched Autona / earth, a commercial autonomous haulage system for mines and quarries built around an autonomous Volvo FH truck and an in-house developed virtual driver. The package is delivered as Transport-as-a-Service, with Volvo providing the vehicle automation stack, site infrastructure, operational support and maintenance rather than selling trucks outright. The system is designed to plug into existing mine haulage operations, signalling a shift towards OEM-managed autonomous fleets where OEMs assume more responsibility for uptime and performance.
