Open-Ended Lithium Pegmatites at Bolt Cutter Central Signal Exploration Upside
Wildcat Resources has reported significant extensions of lithium-bearing pegmatites at its Bolt Cutter Central discovery near Tabba Tabba, with diamond drilling revealing mineralisation over 700 metres down dip. Follow-up drilling and assays are underway, highlighting the project's growing potential.
- Diamond drilling extends Harry Pegmatite Swarm to 700m depth
- Multiple high-grade lithium intercepts confirmed at Bolt Cutter Central
- Lithium mineralisation verified at Hermione Prospect, with further drilling planned
- Pegmatites remain open in all directions, indicating exploration upside
- Company well funded with $55.1 million as of June 2025
Significant Depth Extension at Harry Pegmatite Swarm
Wildcat Resources Limited (ASX, WC8) has announced encouraging results from its recent diamond drilling program at the Bolt Cutter Central lithium discovery, located approximately 10 kilometres west of its flagship Tabba Tabba Lithium-Tantalum Project in Western Australia. The drilling has successfully extended the known pegmatite mineralisation at the Harry Pegmatite Swarm to over 700 metres down dip, a substantial increase that underscores the potential scale of this lithium system.
The diamond drill holes intercepted multiple stacked pegmatite dykes, with visual estimates indicating a significant presence of spodumene, the lithium-bearing mineral. While laboratory assays for these diamond holes are still pending, the geological observations suggest a robust mineralised system that remains open along strike and at depth.
High-Grade Lithium Intercepts Confirmed
Complementing the diamond drilling, reverse circulation (RC) drilling at Harry has returned several high-grade lithium intercepts, including 6.0 metres at 1.5% lithium oxide (Li2O) from 15 metres, 4.0 metres at 2.2% Li2O from 57 metres, and 8.0 metres at 1.1% Li2O from 67 metres. These results reinforce the quality of the mineralisation and provide confidence in the continuity of the pegmatite swarm.
Notably, the pegmatites at Bolt Cutter Central remain open in all directions, presenting multiple avenues for further exploration and resource expansion. The company has also confirmed lithium mineralisation at the nearby Hermione Pegmatite Prospect, although initial drilling there likely missed the main mineralised trend. Follow-up drilling is planned to better delineate this target.
Strategic Exploration and Funding Position
Wildcat is advancing a comprehensive exploration program at Bolt Cutter Central, including further RC drilling to test extensions of the Harry and Hermione pegmatites and to explore three additional high-tenor soil anomaly trends identified in the area. A heritage survey has been completed, with the final report awaited to facilitate ongoing drilling activities.
Financially, Wildcat remains well positioned to support its exploration ambitions, reporting a cash balance of $55.1 million as of 30 June 2025. This strong funding base provides the company with the flexibility to accelerate drilling and evaluation efforts as assay results and geological data continue to emerge.
Context Within the Tabba Tabba Project
The Bolt Cutter Central discovery sits within the broader Tabba Tabba Lithium-Tantalum Project, an advanced development asset with a maiden mineral resource estimate of 74.1 million tonnes at 1.0% Li2O. Tabba Tabba is strategically located near some of the world’s largest hard-rock lithium mines, including Pilgangoora and Wodgina, positioning Wildcat to potentially leverage regional infrastructure and market dynamics as it advances its lithium assets.
Overall, the latest drilling results at Bolt Cutter Central add a compelling chapter to Wildcat’s exploration story, suggesting a richly mineralised pegmatite system with significant depth and strike potential. The company’s methodical approach to drilling, combined with its strong financial footing, sets the stage for continued progress in defining a substantial lithium resource in this emerging Western Australian district.
Bottom Line?
As assays and follow-up drilling progress, Wildcat’s Bolt Cutter Central project could soon reshape the company’s lithium resource profile and market prospects.
Questions in the middle?
- What will the pending assay results from the diamond drill holes reveal about grade continuity at depth?
- How will follow-up drilling at Hermione refine the understanding of its lithium mineralisation potential?
- What impact will the heritage survey findings have on the timing and scope of future exploration activities?
