• Broad, high-grade antimony mineralisation confirmed at Mt Clement with multiple strong intercepts extending beyond the current Resource
• New lode structure intersected with silver mineralisation, representing a new target area for follow-up
• Metallurgical test work underway and drilling to recommence in March 2026 to inform an economic study in the September 2026 quarter

Black Cat Syndicate Limited ('Black Cat' or 'the Company') has received positive results from its 2025 diamond drilling program at the 100%-owned Mt Clement Antimony Project ('Mt Clement'). The 24-hole, 6,904m program primarily targeted the Taipan Lode structure, which hosts the current inferred Resource of 794kt @ 1.7% Sb for 13.2kt contained Sb. Significant results from the Taipan Lode include 5.00m @ 2.52% Sb, 4.14% Pb and 34.38g/t Ag, 1.10m @ 3.10% Sb, 6.37% Pb and 35.10g/t Ag, and 1.50m @ 1.96% Sb, 2.91% Pb and 89.73g/t Ag. These results are consistent with previously reported high-grade intersections and confirm the project's significant growth potential. Additionally, a previously unidentified lode structure was intersected in one hole, returning a broad zone of silver mineralisation with 7.90m @ 26.31g/t Ag, representing a new target area for follow-up. Metallurgical test work is underway, and drilling is planned to recommence in March 2026 to inform an economic study in the September 2026 quarter. The Company has also been invited to join a West Australian government critical minerals delegation to North America in March 2026 to showcase Mt Clement.

The Company has not provided any high-importance, price-sensitive forward-looking financial metrics in the announcement.

Ongoing drilling and metallurgical results will inform an economic study in the September 2026 quarter. The Company plans to recommence drilling at Mt Clement in March 2026.
