Wildcat’s Tabba Tabba and Bolt Cutter: pit design and risk takeaways for planners
Reviewed by Joe Ashwell

First reported on Australian Mining
30 Second Briefing
Wildcat Resources is expanding drilling at its Tabba Tabba and Bolt Cutter Central lithium projects in Western Australia’s Pilbara after defining a stacked pegmatite system about 2.3km long by 0.8km wide at Bolt Cutter, with mineralisation open in most directions. Recent holes have intersected multiple spodumene-bearing pegmatites, supporting further resource definition and development studies across both projects. For geotechnical and mine planners, the scale and stacked geometry point to a potentially complex open-pit design with careful pit wall and groundwater management.
Technical Brief
- Drilling at Bolt Cutter Central has delivered “standout” spodumene intercepts, prompting immediate programme expansion.
- Wildcat is concurrently advancing lithium targets at both Bolt Cutter Central and the nearby Tabba Tabba project.
- The projects sit in Western Australia’s Pilbara, implying hard-rock open-pit conditions in Archean greenstone/pegmatite terrane.
- Strong intercepts at depth suggest potential for multi-bench pit development rather than shallow, single-phase extraction.
- Parallel work on resource growth and “development work” indicates early-stage mine design and economic assessments are underway.
- Tabba Tabba’s inclusion in the current campaign points to a potential multi-asset lithium hub strategy.
- For similar Pilbara lithium systems, stacked pegmatites often require careful inter-ramp angle optimisation and staged pushbacks.
Our Take
The 2.3 km by 0.8 km pegmatite footprint at Bolt Cutter Central, referenced in multiple earlier drilling updates, suggests that any new Tabba Tabba hits could quickly be benchmarked by the market against this known scale, influencing how investors value additional discoveries in Western Australia.
Within our 103 lithium‑tagged pieces, only a subset involves Pilbara hard‑rock systems of this apparent continuity, which signals that Wildcat’s Western Australian portfolio is starting to sit alongside more established spodumene players in terms of geological potential, even if it remains at an earlier development stage.
