Wildcat Resources has delivered promising early metallurgical results from its Bolt Cutter Central lithium discovery in WA’s Pilbara, showing spodumene recoveries averaging 82.5% using flotation methods from its Tabba Tabba project. Exploration drilling has extended the mineralised footprint to over 2.3km with multiple significant lithium intercepts.
- Maiden metallurgy shows 82.5% spodumene recovery with 5.66% Li2O concentrate
- Mineralised area at Bolt Cutter Central extended to 2.3km by 0.8km
- Multiple strong lithium intercepts from recent drilling reported
- Resource modelling underway with Q3 2026 reporting targeted
- Wildcat holds A$43.3 million cash as at March 2026
Strong Metallurgical Signature Mirrors Tabba Tabba Process
Wildcat Resources Limited (ASX:WC8) has revealed encouraging maiden metallurgical test results from its Bolt Cutter Central lithium discovery, located just 10km west of the company’s Tabba Tabba project in Western Australia’s Pilbara. Using the Whole of Ore Flotation method designed for Tabba Tabba, the company achieved an average spodumene recovery of 82.5% across three composite samples, with concentrate grades averaging 5.66% Li2O. This early-stage testwork, conducted on small-scale composites, outperformed expectations despite no Bolt Cutter-specific processing optimisation to date.
The standout composite BCM002 replicated the high recovery and concentrate grade of Tabba Tabba’s Leia pegmatite, delivering 87.1% recovery at 5.94% Li2O. Other composites showed strong upgrade potential, though BCM001’s flotation losses suggest finer grinding could further improve recoveries. While lab-scale results tend to slightly overstate recoveries compared to full-scale operations, Wildcat’s confidence is bolstered by the consistent metallurgical signature between Bolt Cutter Central and Tabba Tabba, promising streamlined processing integration.
Drilling Expands Mineralised Footprint and Confirms Multiple Lithium Zones
Recent drilling campaigns, combining reverse circulation and diamond core methods, have extended the known lithium mineralisation at Bolt Cutter Central to an area roughly 2.3km long and 0.8km wide. Notably, infill drilling at the Harry pegmatite swarm returned robust near-surface intercepts such as 7.1m at 1.3% Li2O and 4.3m at 1.4% Li2O, underscoring the discovery’s potential. The Hermione trend also saw significant strike extensions with stacked pegmatites yielding intercepts like 7m at 1.1% Li2O and 5m at 1.2% Li2O over 300m from initial drill holes.
Drilling in the adjacent tenement E45/5416 confirmed the system’s eastward continuity, with lithium mineralisation identified 1.2km beyond the current footprint. This suggests further upside potential as geological, geochemical, and geophysical data are integrated to prioritise new drill targets. Resource modelling is currently underway, with Wildcat targeting a resource estimate and reporting in the third quarter of 2026.
Well-Funded and Positioned for Next Development Phase
Wildcat maintains a strong financial position with A$43.3 million in cash as of March 31, 2026, supporting ongoing exploration and development activities. The company plans to advance resource modelling, complete further infill and extensional drilling, and undertake more comprehensive metallurgical testing using larger composite samples. These next steps aim to refine mineralogical understanding, optimise processing parameters, and expand the resource base.
Bolt Cutter Central’s proximity to the advanced Tabba Tabba project, which hosts a maiden JORC Mineral Resource Estimate of 74.1Mt at 1.0% Li2O and a Probable Ore Reserve of 46.3Mt at 0.99% Li2O, positions Wildcat well to leverage synergies in development and processing. The Tabba Tabba DFS is nearing completion, with a well-defined process design that Bolt Cutter Central’s mineralisation appears compatible with, potentially accelerating project advancement.
Bottom Line?
Bolt Cutter Central’s strong early metallurgical results and expanding mineralisation footprint set the stage for a critical resource update and processing optimisation in Q3 2026.
Questions in the middle?
- How will full-scale metallurgical testing impact spodumene recovery expectations at Bolt Cutter Central?
- What are the implications of the eastward mineralisation extension into E45/5416 for Wildcat’s exploration strategy?
- How might the integration of Bolt Cutter Central with Tabba Tabba influence Wildcat’s development timeline and capital allocation?
