• Initial grade-control assays show shallow high-grade gold
• Notable intercepts include 11m @ 8.55 g/t Au and 3m @ 10.05 g/t Au
• Results support shallow stacked lode architecture

Redcastle Resources Ltd is pleased to report initial assay results from the completed 8,810m grade-control reverse circulation (RC) drilling programme at Queen Alexandra (QA), located approximately 700m west of Redcastle Reef (RR) within the Redcastle Gold Project in Western Australia's Eastern Goldfields. The initial results support shallow high-grade gold mineralisation within the interpreted Kestrel and Kestrel Hanging Wall lode positions across the QA development area. Standout uncut intercepts include 11m @ 8.55 g/t Au from 14m and 3m @ 10.05 g/t Au from 21m. The results are broadly consistent with the 2025 MRE geological interpretation and support a shallow stacked lode architecture, principally across the interpreted Kestrel and Kestrel Hanging Wall lode positions. Further QA grade-control assays remain outstanding and will be reported, where material, following receipt, validation and QA/QC review.

The initial assay results from the QA grade-control drilling programme will be incorporated into the refinement of the QA mine plan, aiming to optimise mining operations and logistics across the combined RR-QA development area.
