• New high-grade gold discovery at Beatty Park Sth with results up to 169g/t Au
• Significant RC drilling results from Tambourah King gold project
• High-grade antimony, silver and copper confirmed at Speewah Nth project

Tambourah Metals Ltd (ASX:TMB) has reported strong results from its gold and critical minerals exploration activities during the September 2025 quarter. At the Beatty Park Sth project, the company's maiden aircore and slim-line RC drilling program returned outstanding high-grade gold results, including 24m at 18.8g/t Au from 20m and 10m at 38.9g/t Au from 22m. The company plans to follow up these initial results with a 4,000m aircore program. At the Tambourah Gold project, in-fill RC and diamond drilling at the Tambourah King prospect returned further high-grade gold intersections, including 2m at 49.7g/t Au from 50m. Additional in-fill drilling is planned to support a preliminary resource estimate. Exploration drilling at the Alexandria prospect also returned promising results. At the Speewah Nth project, rock sampling along the 7km Chapmans-Haydens corridor confirmed the potential for high-grade antimony, silver and copper mineralization, with results up to 4.54% Sb, 517g/t Ag and 3.62% Cu. Seven antimony targets have been identified for planned RC drilling.

Tambourah plans to follow up the new high-grade gold discovery at Beatty Park Sth with a 4,000m aircore drilling program, and conduct additional in-fill drilling at the Tambourah King prospect to support a preliminary resource estimate. The company will also commence RC drilling to test the identified antimony targets at the Speewah Nth project.
