• Aircore drilling at Beatty Park Sth defined two high-priority gold targets for testing
• Tambourah's drilling continues to advance the understanding of the Tambourah King lode system
• Tambourah is targeting critical minerals silver and antimony at the Speewah Nth project

Tambourah Metals Limited (ASX:TMB) is pleased to provide an update on the Company activities for the quarter ending 31 March 2026. Key highlights include:GOLD- Beatty Park Sth - Bryah Project: Integration of geophysical and geochemical data defined two high-priority gold targets for testing with aircore drilling. The drilling returned multiple anomalous gold intervals, elevating the area to a priority follow-up target. RC and diamond drilling is planned to test below the shallow anomalism.- Tambourah Gold Project: Tambourah's drilling continues to advance the understanding of the Tambourah King lode system by defining grade distribution and continuity within the top 100 metres to a level suitable for initial resource estimation. Significant high-grade gold intersections were reported from the Tambourah King, Alexandria and Young Australian prospects.CRITICAL MINERALS- Speewah Nth: Tambourah is targeting critical minerals silver and antimony, within a 7km long zone of epithermal - mesothermal veining. The Company has defined seven priority drill targets for RC drilling where strongly anomalous outcrop sampling is supported by polymetallic mineralisation in historic drill intersections.The Company's cash position was $5.35M at 31 March 2026, with exploration expenditure of approximately $440,000 during the quarter.

Tambourah plans to undertake the following activities in the next quarter:GOLD- Beatty Park Sth: Submit 1m split samples from aircore drilling for assay, conduct aircore drilling to test the T2 gold-in-soil anomaly, and plan RC and diamond drilling to target depth extensions to high-grade gold mineralisation.- Tambourah: Conduct in-fill RC drilling at Tambourah King to support an initial resource estimate, and extend shallow RC drilling at Young Australian and Alexandria.CRITICAL MINERALS- Speewah Nth: Commence RC drilling of polymetallic antimony-silver-copper targets.
