Black Cat Syndicate’s latest drilling at Mt Clement confirms strong, high-grade antimony mineralisation extending beyond current resources, advancing the project towards a pivotal economic study.
- Completion of 24-hole, 6,904m diamond drilling program
- Significant high-grade antimony, lead, and silver intercepts beyond existing resource
- Discovery of new lode structure with notable silver mineralisation
- Metallurgical test work underway focusing on antimony recoveries
- Economic study scheduled for September 2026 quarter
Drilling Success at Mt Clement
Black Cat Syndicate Limited has announced the completion of a comprehensive diamond drilling program at its 100% owned Mt Clement Antimony Project in Western Australia. The 24-hole campaign, totalling nearly 7,000 metres, primarily targeted the Taipan Lode, which currently hosts an inferred resource of 794,000 tonnes at 1.7% antimony, containing approximately 13,200 tonnes of antimony.
The assay results reveal multiple broad zones of high-grade antimony mineralisation, with some intercepts extending beyond the boundaries of the current resource. Noteworthy results include a 5-metre intercept grading 2.52% antimony alongside significant lead and silver credits, and other high-grade zones featuring antimony grades above 2.9%.
New Geological Insights and Discovery
Beyond the Taipan Lode, drilling intersected additional mineralisation in the Gwardar Lode, validating surface geological mapping and enhancing understanding of the deposit’s complexity. A particularly exciting development was the identification of a previously unknown lode structure, highlighted by a broad zone of silver mineralisation with assays up to 26.31 grams per tonne silver. This discovery opens new exploration avenues and potential resource expansion.
Metallurgical Progress and Strategic Positioning
Metallurgical test work focusing on antimony recoveries is currently underway, building on earlier studies that showed promising recoveries of around 85% for antimony, lead, and silver. These results will be critical in refining the processing flowsheet and underpinning the forthcoming economic study scheduled for the September 2026 quarter.
Strategically, Mt Clement benefits from proximity to the Paulsens Gold Operation, located just 30 kilometres away, allowing potential utilisation of existing infrastructure to reduce capital expenditure and accelerate project development. The project’s location within the Northern Australia Infrastructure Facility zone further enhances its appeal, aligning with government priorities to develop critical mineral supply chains.
Critical Mineral Importance and Market Context
Antimony is recognised as a critical mineral by both Australian and US governments, essential for defence applications and emerging clean energy technologies. With China currently dominating global supply, Mt Clement’s advancement is timely amid growing geopolitical and supply chain considerations. Black Cat’s participation in a West Australian government delegation to North America in March 2026 underscores the project’s strategic significance on an international stage.
Looking ahead, Black Cat plans to recommence drilling in March 2026 to further delineate and expand the resource, while metallurgical optimisation continues. The combined efforts aim to deliver a robust economic study that could position Mt Clement as a cornerstone of Australia’s critical minerals sector.
Bottom Line?
Mt Clement’s expanding high-grade antimony footprint and advancing metallurgical work set the stage for a defining economic study later this year.
Questions in the middle?
- How will metallurgical test results impact the final processing strategy and project economics?
- What is the potential scale and grade of the newly discovered lode structure at Mt Clement?
- How might government critical minerals initiatives influence project financing and development timelines?
