Black Cat Expands Big Sarah Tenure with High-Grade Gold Vein Discoveries

Strategic Tenure Expansion

Black Cat Syndicate Limited has announced a substantial increase in its landholding at the Paulsens Gold Operation in Western Australia, adding approximately 460 square kilometres to its portfolio. This expansion is achieved through the acquisition and pegging of three key tenements, Cheela, Silent Sisters, and New Morning, strategically positioned around the Big Sarah prospect.

The newly acquired tenements lie within the highly prospective Barring Downs and Nanjilgardy fault zones, geological structures known to host significant mineralisation. Notably, the Cheela tenement contains rock chips with copper grades as high as 32.32%, alongside untested bedrock electromagnetic conductors, while Silent Sisters holds historical lead and silver production records from the 1950s. New Morning, recently pegged by Black Cat, overlays a historical geophysical and geochemical anomaly adjacent to Cheela’s untested conductors.

Exploration Highlights at Big Sarah

Reconnaissance surface sampling at Big Sarah has delineated three distinct vein corridors extending up to 15 kilometres in strike length and up to 100 metres in width. These corridors comprise multiple sub-parallel quartz-oxide veins, some reaching widths of approximately one metre. Sampling efforts, including 164 rock samples from 19 areas of interest, have identified a roughly 4-kilometre-long zone of gold-bearing quartz veining within the Central Vein Corridor.

Gold assay results are compelling, with recent samples returning grades up to 2.91 g/t Au and historical samples reaching as high as 24.51 g/t Au. These findings underscore the prospect’s potential for significant gold mineralisation, warranting further investigation.

Next Steps and Broader Context

Black Cat is finalising drill plans for the September 2025 quarter to test these newly identified targets. The company’s Managing Director, Gareth Solly, highlighted the strategic importance of the acquisitions and the promising nature of the exploration results, emphasizing the potential to grow the Big Sarah prospect substantially.

This tenure expansion complements ongoing activities at Black Cat’s other operations, including underground drilling at Paulsens and surface drilling at Kal East. The company’s broader portfolio also includes the Coyote and Mt Clement projects, which offer additional growth opportunities in gold and antimony.

With statutory approvals pending for the acquisitions and drilling yet to commence, the market will be watching closely for forthcoming assay results that could validate the exploration upside at Big Sarah and surrounding tenements.
