110m at 1.2% Li2O Highlights Tabba Tabba’s Lithium Potential in Latest Drilling

Strong Assay Results Reinforce Tabba Tabba’s Potential

Australian lithium explorer Wildcat Resources Limited (ASX – WC8) has released its final metallurgical assay results from diamond drilling at the Leia Pegmatite within the Tabba Tabba Lithium-Tantalum Project in Western Australia. The standout intercept of 110.1 metres grading 1.2% lithium oxide (Li2O) from 195 metres depth underscores the exceptional thickness and consistent lithium mineralisation across the deposit.

These latest results represent a significant uplift compared to adjacent drill holes, with some intercepts showing a 21% to 40% increase in grade-thickness product. For example, hole TAMT033’s intercept outperforms a nearby hole drilled just 10 metres away, while TAMT035 shows a 40% improvement over a hole 35 metres distant. Such positive deviations from the block model expectations could translate into enhanced resource confidence and improved project economics.

Advancing the Definitive Feasibility Study

The metallurgical drilling program, a critical component of the ongoing Definitive Feasibility Study (DFS), is now complete. The DFS aims to refine the project’s development plan, incorporating these new assay results to optimise mining and processing strategies. Wildcat’s geology team, led by Torrin Rowe, highlighted the potential for further upside as pending assay results from up-dip holes are awaited.

Tabba Tabba’s resource base remains robust, 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. The Leia Pegmatite alone accounts for 63% of the lithium resource, making it the project’s cornerstone. The project’s proximity to major lithium operations such as Pilgangoora and Wodgina further positions it strategically within Western Australia’s lithium hub.

Financial and Strategic Position

Wildcat enters the next phase of development with a solid cash balance of $55.1 million as of June 30, 2025, providing the financial flexibility to advance the DFS and regional exploration programs. The company plans to continue metallurgical testwork, refine resource models, and pursue discovery strategies to expand the project’s footprint.

While the results are encouraging, some minor downgrades in certain holes and pending assays remind investors that exploration is an evolving process. Nonetheless, the data reinforce Wildcat’s position as a promising lithium developer in a market hungry for new supply amid the global energy transition.
