Wildcat’s Bolt Cutter lithium: enlarged Harry–Hermione system for mine planners
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Wildcat Resources reports that its Bolt Cutter Central lithium project in the Pilbara is significantly larger and more continuous than earlier drilling suggested, with the Harry and Hermione pegmatite zones now interpreted as a single, expanded mineralised system. Step-out drilling has extended spodumene-bearing pegmatites along strike and at depth, improving continuity for potential large-scale open-pit design and simplifying resource modelling. The enlarged footprint strengthens the project’s strategic position in Western Australia’s hard-rock lithium belt and will drive updated JORC resource estimates and mine planning studies.
Technical Brief
- For similar Pilbara hard-rock mining projects, such continuity typically improves conversion from resource to reserve.
Our Take
Lithium pieces make up only a small subset of the 654 Mining stories in our database, so Pilbara exploration plays like Wildcat Resources’ Bolt Cutter tend to attract outsized attention compared with more mature iron ore or gold coverage in Australia.
Within the 1229 Projects-tagged items, Pilbara lithium entries frequently progress from early drilling to rapid resource definition, suggesting that any step-change discovery at Bolt Cutter could move quickly into scoping and JV/offtake discussions if results hold up.
Our lithium keyword set increasingly features Pilbara projects constrained more by power, water and logistics than geology, so early planning for shared infrastructure around Bolt Cutter may be as critical to long-term value as the scale of the discovery itself.
