Summary:Mount Holland lithium mine gets approval to double output. SQM-Wesfarmers JV expands Western Australia lithium production as spodumene prices surge to 2-year highs....
In a pivotal development for global battery supply chains, Mount Holland lithium mine—a flagship hard-rock asset in Western Australia—has received regulatory approval to double its lithium production capacity amid a sharp lithium spodumene price surge. Owned by SQM and Wesfarmers (50:50 JV, Covalent Lithium), the expansion will position Mount Holland as one of the world’s largest and most cost-effective lithium producers, addressing tightening global supply and surging EV demand.
Project Overview: Mount Holland’s Expansion Milestone
Located 400 km east of Perth, Mount Holland lithium mine commenced production in March 2024, with initial capacity of 2.2 million tonnes per annum (mtpa) of spodumene concentrate and 50,000 tpa of battery-grade lithium hydroxide. The newly approved expansion duplicates existing processing infrastructure and brings online new ore deposits, lifting total spodumene capacity to 4.4 mtpa—a 100% increase—while maintaining lithium hydroxide output at 50,000 tpa.
| Parameter | Specification |
|---|---|
| Project Name | Mount Holland Lithium Mine |
| Location | Western Australia (400km east of Perth) |
| Ownership | SQM (50%) / Wesfarmers (50%) |
| Current Capacity | 2.2 mtpa spodumene; 50 ktpa LiOH |
| Expanded Capacity | 4.4 mtpa spodumene; 50 ktpa LiOH |
| Expansion Approval | May 2026 (Regulatory Filing) |
| Spodumene Price (May 2026) | $2,890/t (2-year high) |
| Production Start | March 2024 |
The expansion extends the mine’s operational life by decades, leveraging Western Australia’s stable regulatory environment, established mining infrastructure, and proximity to export ports—critical advantages for scaling hard rock lithium mining operations.
Price Surge Catalyst: Economics Drive Expansion
The Australian lithium mine expansion comes as lithium spodumene price surge to a 2-year high of $2,890/t (May 12, 2026), up from December 2025 lows. While still below the 2022 record of $6,110/t, the sustained rally has unlocked robust margins for Australian producers, triggering a wave of restarts and expansions across the sector.
For the SQM Wesfarmers lithium JV, the expansion is economically compelling. At current prices, the doubled spodumene output will generate an additional $600+ million in annual revenue, with low incremental operating costs due to existing site infrastructure and workforce. The project’s proximity to Perth and coastal ports minimizes logistics expenses, further enhancing competitiveness in the global lithium supply chain.
Strategic Significance for Global Lithium Supply
Australia dominates global hard-rock lithium production, accounting for over 45% of global spodumene supply in 2025. The Mount Holland lithium mine expansion reinforces this leadership, adding 2.2 mtpa of high-quality spodumene concentrate to global markets—enough to supply approximately 10% of global EV battery demand.
Unlike brine-based operations, hard-rock lithium production offers consistent, scalable output with predictable quality, making it ideal for long-term offtake agreements with battery manufacturers and chemical producers. The expansion aligns with global efforts to diversify lithium supply away from concentrated regions, reducing geopolitical risks for EV and energy storage stakeholders.
Operational & Market Context
The Australian lithium mine expansion follows a broader industry trend: Core Lithium restarted its Finniss project in May 2026, while Mineral Resources reopened the Bald Hill mine and expanded Mt Marion capacity amid favorable pricing. This collective ramp-up positions Western Australia as the epicenter of global lithium supply growth through 2030.
Mount Holland’s phased expansion will be executed with minimal disruption to existing operations, leveraging the JV’s operational expertise and modular processing design. First expanded spodumene production is targeted for Q4 2026, with full 4.4 mtpa capacity achieved by mid-2027.
Conclusion
The approval to double output at Mount Holland lithium mine marks a defining moment for Australian lithium mine expansion and the global energy transition. Driven by the lithium spodumene price surge, the SQM-Wesfarmers JV’s strategic move will significantly boost Western Australia lithium production, strengthen the global lithium supply chain, and deliver reliable, high-quality spodumene to EV and battery manufacturers worldwide.
As hard-rock lithium mining continues to scale, Mount Holland’s expansion sets a benchmark for balancing operational excellence, market responsiveness, and sustainability—solidifying Australia’s role as the cornerstone of the global lithium economy for decades to come.
