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

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.
