Tambourah Reports 169g/t Gold and Multi-Metal Hits, Raises $3.4M

Exploration Breakthroughs in the Bryah Basin

Tambourah Metals Ltd (ASX – TMB) has delivered a compelling update for the September 2025 quarter, revealing significant progress across its gold and critical minerals portfolio in Western Australia. The standout news comes from the Beatty Park South prospect within the Bryah Basin, where maiden aircore and follow-up reverse circulation (RC) drilling have uncovered exceptionally high-grade gold mineralisation. Assays include a remarkable 10 meters at 38.9 grams per tonne (g/t) gold, highlighted by a 1-meter sample grading 169g/t Au, confirming the presence of a robust, shallow gold system open to further expansion.

These results mark a pivotal moment for Tambourah, as the Beatty Park South discovery taps into a geological setting known to host major gold and base metal deposits in the region. The company plans an extensive 4,000-meter aircore drilling campaign to delineate the extent of mineralisation and test the broader soil anomaly, which remains only partially explored.

Tambourah King and Broader Gold Targets

At the Tambourah Gold Project, recent drilling has reinforced the potential for high-grade gold mineralisation near surface. In-fill RC drilling at Tambourah King returned impressive intercepts, including 2 meters at 49.7g/t Au and 1 meter at 97.6g/t Au, supporting plans for a preliminary resource estimate. Exploration at Alexandria also intersected encouraging gold grades, with diamond drilling results pending, which could further enhance the project’s resource profile.

Tambourah’s broader gold exploration footprint includes the Tambina and Cheela projects, where sampling and drilling continue to refine targets. Although no significant assays were reported from Cheela’s recent drilling, the project’s proximity to major gold deposits keeps it on the company’s radar for future work.

Critical Minerals Momentum at Speewah North

Beyond gold, Tambourah is advancing its critical minerals ambitions at the Speewah North project, where rock chip sampling has confirmed high-grade antimony (up to 4.54%), silver (up to 1910g/t), and copper (up to 7%) mineralisation within polymetallic quartz veins. Seven priority antimony targets have been identified for upcoming RC drilling, underscoring the potential for a polymetallic deposit in this underexplored corridor. The project’s location within the Speewah Dome, a region known for significant mineralisation, adds strategic value to Tambourah’s portfolio.

Financial Position and Next Steps

Financially, Tambourah Metals strengthened its position during the quarter, raising approximately $3.4 million through a combination of a placement, entitlement issue, and option conversions. The company ended the period with $1.695 million in cash, supporting ongoing exploration activities. Exploration expenditure totaled $546,000, with no mining production or development costs incurred.

Looking ahead, Tambourah is poised to expand its drilling programs, particularly at Beatty Park South and Speewah North, while awaiting assay results from recent diamond drilling at Tambourah King and Alexandria. These developments will be critical in shaping the company’s resource estimates and advancing its projects towards potential development.
