- Pilgangoora mineral resource sees major upgrade
- Lithium oxide content rises sharply j
- Exploration potential remains strong
The lithium sector on the ASX 200 is buzzing once again as Pilbara Minerals (ASX:PLS) delivered a significant mineral resource update for its flagship Pilgangoora project. The announcement spurred a near 5% intraday surge in the company’s share price, reflecting investor enthusiasm around its expanded resource base and exploration outlook.
Major Resource Growth at Pilgangoora
Pilbara Minerals revealed that the total mineral resource at its Pilgangoora operations in Western Australia has grown by 10%, with contained lithium oxide (Li₂O) rising by 23%. The updated resource now holds approximately 5.7 million tonnes of lithium oxide at a higher average grade of 1.28% Li₂O.
This revision captures the results of the FY24 and FY25 drilling programs, which included 364 drill holes. These focused on exploring down-dip extensions across a 7-kilometre strike length, highlighting the scale and continuity of the deposit.
Such a boost reinforces Pilgangoora’s status as one of the world’s largest hard-rock lithium operations—strategically positioned to support long-term supply for the growing battery metals sector.
Exploration Potential Still Untapped
Despite a slowdown in exploration activity from March 2025 as part of broader cost-efficiency efforts, Pilbara Minerals noted substantial upside potential remains. Key zones such as the "Bridge Zone" between the Central and North areas remain largely untested below 200 metres. This suggests more lithium could still be discovered as the company continues to evaluate deeper mineralisation targets.
Strategic Positioning for Global Lithium Demand
According to management, the latest resource upgrade further strengthens Pilbara Minerals’ position as a top-tier global lithium supplier. The company emphasised that its large-scale operations, robust supply chain, and financial resilience provide a strong foundation to adapt to evolving market dynamics.
While the broader lithium market has experienced volatility, this update signals confidence in the company’s asset quality and long-term strategic value. Its ability to grow resources while maintaining operational discipline is a key differentiator within the ASX 100 and ASX 300 indices.
The enhanced Pilgangoora resource not only cements Pilbara Minerals’ leadership in the lithium sector but also positions the company to benefit as lithium demand rebounds. With ongoing exploration and operational optimisation, market watchers may continue to track developments closely as the company navigates the evolving clean energy transition.
