Tambourah Metals Ltd has commenced a 10-hole reverse circulation drilling program at the Beatty Park South gold prospect, located 160 kilometres north of Meekatharra in Western Australia.

The current program follows aircore drilling completed across altered ultramafics that returned shallow high-grade intercepts, including 6 metres at 25.8 grams per tonne gold from 30 metres with a 1-metre sample at 126 grams per tonne, and 10 metres at 38.9 grams per tonne gold from 22 metres featuring a 1-metre intercept at 169 grams per tonne.

The reverse circulation campaign comprises five precollars intended for Western Australia Government Exploration Incentive Scheme co-funded diamond drilling. The diamond tails will test depth and strike extensions to a vertical depth of approximately 250 metres beneath the known mineralisation.

An additional five exploration holes, each planned to a depth of 150 metres, will test blind targets identified by multi-element geochemistry and a sub-audio magnetic geophysical survey over the Beatty Park anomaly.

Once work concludes at Beatty Park South, the drill rig will move 4 kilometres south of the Harmony gold mine to Baxter South to test a historic intercept of 8 metres at 5.5 grams per tonne gold from 67 metres within Ravelstone Formation sediments. That work aims to intersect the northwest-plunging contact that hosts the Harmony deposit further north.

A diamond drilling program of approximately 1,000 metres is scheduled to start in mid-to-late August following the completion of the reverse circulation holes.

The Beatty Park South operations form part of the company's broader exploration schedule, which included a reverse circulation drilling program at the Tambourah King prospect within its Pilbara gold project earlier in July. Following the completion of in-fill reverse circulation drilling at Tambourah King, the company plans to prepare a maiden resource estimate for that prospect.

Regional exploration activity has also advanced nearby, with Pilbara Gold Ltd having declared its Mineral Rights Agreement unconditional at the neighbouring Mt York gold project within 50 kilometres of the project in August 2026, securing control over neighbouring greenstone geology and a 1,500-metre extension to the Main Hill deposit.
