• New Tolmer diamond drilling assays confirm local structural model analogous to eastern portion of historical Tarcoola goldfield
• 'Western silver zone' target recently enhanced by western and southern extensions of silver, the emergence of high-grade gold, and soil assays suggesting further extensions
• Follow up 'western silver zone' drilling anticipated for H1 2026 alongside other major programs

Barton Gold Holdings Limited (ASX:BGD, OTCQB:BGDFF, FRA:BGD3) is pleased to announce assays results from diamond drilling (DD) at the high-grade Tolmer gold and silver prospect, located at the Company's South Australian Tarcoola Gold Project. Three holes totalling 595.3m were recently drilled in the 'eastern gold zone' to identify structural controls and guide future targeting. The new Tolmer diamond drilling assays confirm the local structural model is analogous to the eastern portion of the historical Tarcoola goldfield, which hosts the Company's Perseverance Mine. The 'western silver zone' target has been recently enhanced by western and southern extensions of silver, the emergence of high-grade gold, and soil assays suggesting further extensions. Barton will continue its review, with a focus on the western silver zone, and expects to follow up with further drilling during 2026.

Barton expects that further follow up drilling in the 'western silver zone' will follow this review, targeting extensions of this mineralisation alongside other drilling programs planned for calendar year 2026.
