Tambourah Metals (ASX:TMB) has commenced a 2,000-metre aircore drilling program at its Baxters Sth prospect within the Peak Hill Mineral Field, Western Australia, targeting the extent of high-grade supergene gold mineralisation identified during a two-hole RC drilling program completed in September 2026.
Key Points
- A 2,000m aircore drilling program has commenced at Baxters Sth to assess the extent of high-grade supergene gold mineralisation.
- Previous RC drilling returned 4m at 41.7g/t Au from 55m in BXRC26002 and 6m at 9.5g/t Au from 64m in BXRC26001.
- The initial phase will comprise aircore holes on 40m centres around the RC intersections, covering an area of 160m by 160m.
- Baxters Sth is located within the Peak Hill Mineral Field, 160km north of Meekatharra, and lies 4 kilometres south of the Harmony gold deposit.
Baxters Sth Drilling Program Details
The aircore drilling program is designed to test the extent of supergene gold mineralisation around intersections reported from Tambourah's RC drilling completed in September 2026. The initial phase will consist of aircore holes drilled on 40-metre centres around those RC intersections, covering an area of 160 metres by 160 metres. The drill crew and Tambourah personnel are mobilising to the Baxters Sth site. Drilling will systematically target the weathered zone overlying shales of the Ravelstone Formation. The RC program itself targeted a historical gold intersection from drilling completed in the 1990s, specifically 8m at 5.05g/t Au from 67m in PHRC0977.
Location and Geological Context at Peak Hill
Baxters Sth is situated within the Peak Hill Mineral Field in Western Australia, located 160 kilometres north of Meekatharra. The prospect lies 4 kilometres south of the Harmony gold deposit, within an area of renewed gold exploration around the historic Peak Hill gold operations, now owned by Great Boulder Resources. According to the filing, the gold distribution within the weathered zone may help inform the assessment of the underlying primary source, which the company has described as a target for planned deeper drilling.
Upcoming Activities Across Tambourah's Project Portfolio
Tambourah disclosed several upcoming activities across its project portfolio. At the Bryah Gold Project, drill core sampling and assaying is planned at Beatty Park Sth. At the Tambourah Gold Project, the company intends to re-sample 1-metre split samples corresponding to anomalous Tambourah King composite samples, and to progress resource work at Tambourah King including data validation, density measurements and preliminary metallurgical sampling. At its Coondina critical minerals project, systematic rock sampling of a recently identified silver-, bismuth- and copper-bearing magmatic-hydrothermal system is planned, alongside ongoing data flow from a CSIRO research collaboration and LCT-pegmatite targeting.
