Wildcat Resources Limited (ASX: WC8) has announced a 300m northerly extension of spodumene mineralisation at its Bolt Cutter Central lithium discovery in Western Australia, expanding the known footprint to over 2.3km northwest and up to 800m northeast. Metallurgical drilling has intercepted spodumene in all holes, with further drilling and metallurgical testing planned.
- Bolt Cutter Central lithium mineralisation extended by ~300m north, footprint now over 2.3km
- Metallurgical drill holes intercepted spodumene with lithium grades up to 1.6% Li2O
- RC drilling to commence imminently for extensional and infill resource modelling
- Metallurgical testwork underway to assess processing viability for Tabba Tabba mining hub
- Wildcat holds $48.5 million cash as at December 2025, supporting ongoing exploration and development
Extension of Lithium Mineralisation at Bolt Cutter Central
Australian lithium explorer Wildcat Resources Limited (ASX:WC8) has reported a significant extension of spodumene mineralisation at its Bolt Cutter Central discovery in Western Australia’s Pilbara region. Recent diamond drilling has extended the interpreted lithium-bearing pegmatite system approximately 300 metres north, bringing the total known strike length to more than 2.3 kilometres northwest and up to 800 metres northeast. This discovery remains open in most directions, indicating potential for further expansion.
The Bolt Cutter Central project is situated about 10 kilometres west of Wildcat’s Tabba Tabba Project, an advanced lithium and tantalum development asset with a maiden JORC Mineral Resource Estimate of 74.1 million tonnes at 1.0% Li2O and a Probable Ore Reserve of 46.3 million tonnes at 0.99% Li2O.
Drilling Results and Metallurgical Insights
Three recent diamond drill holes (BCDD004, BCDD005, and BCDD006) along the northern extensional line intercepted visual spodumene mineralisation, with assays pending and expected within 4 to 8 weeks. Concurrently, metallurgical drilling comprising three diamond holes (BCMT001-003) intercepted spodumene in all holes, with notable lithium grades including:
- 9.4m at 1.3% Li2O from 23.2m (BCMT001)
- 8.1m at 1.2% Li2O from 39.7m (BCMT001)
- 2.3m at 1.6% Li2O from 51.7m (BCMT001)
- 8.1m at 1.0% Li2O from 34.1m (BCMT002)
- 7.6m at 1.4% Li2O from 32.1m (BCMT003)
These intercepts represent estimated true widths and confirm the presence of a stacked pegmatite system. Metallurgical testwork has commenced on selected core samples to determine mineral deportment and lithium recovery rates, aiming to assess the suitability of the material as feedstock for processing at the nearby Tabba Tabba mining hub.
Next Steps and Project Development
Wildcat plans to initiate reverse circulation (RC) drilling imminently to both extend the discovery further and infill drill lines for resource modelling purposes. Additionally, reconnaissance drilling has begun on the adjacent tenement E45/5416, which was recently acquired and lies just 2.3 kilometres from Tabba Tabba.
Environmental studies are underway, and the company intends to lodge a Mining Lease application as part of advancing the project towards development. Wildcat reported a strong cash position of $48.5 million as at 31 December 2025, providing financial capacity to support ongoing exploration and development activities.
Context within Wildcat’s Lithium Portfolio
The Bolt Cutter Central discovery complements Wildcat’s Tabba Tabba Project, which is located nearby and benefits from existing JORC-compliant Mineral Resources and Ore Reserves. Tabba Tabba is positioned close to major lithium mining operations in the Pilbara, including Pilgangoora and Wodgina, which are among the world’s largest hard-rock lithium mines.
Wildcat’s ongoing exploration and metallurgical programs at Bolt Cutter Central aim to delineate further mineralisation and assess processing viability, contributing to the company’s broader strategy of developing a lithium hub in the Pilbara region.
One should note that while visual spodumene mineralisation has been logged, laboratory assay results are required to confirm grades and widths. Assays from the recent northern extension drilling are awaited, and metallurgical testwork results will provide further insights into the deposit’s processing characteristics.
Bottom Line?
Wildcat’s extension of spodumene mineralisation at Bolt Cutter Central and ongoing metallurgical testing mark important steps, but assay results and further drilling will be critical to define the resource and assess development potential.
Questions in the middle?
- How will pending assay results from the northern extension drilling influence the resource model at Bolt Cutter Central?
- What metallurgical recovery rates and processing characteristics will emerge from the ongoing testwork, and how might these impact project economics?
- How will environmental studies and the Mining Lease application process progress, and what timelines might be expected for potential development?
