Tolmer Diamond Assays Enhance Local Structural Model

Peak assays of 465 g/t Ag & 20.2 g/t Au infill high-grade target area

ADELAIDE, AU / ACCESS Newswire / December 8, 2025 / HIGHLIGHTS

• New Tolmer diamond drilling assays confirm local structural model analogous to eastern portion of historical Tarcoola goldfield, which hosts the Company's Perseverance Mine

‘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^[1]

• Follow up ‘western silver zone' drilling anticipated for H1 2026 alongside other major programs

Barton Gold Holdings Limited (ASX:BGD)(OTCQB:BGDFF)(FRA:BGD3) (Barton or Company) 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 (Tarcoola). Three holes totalling 595.3m were recently drilled in the ‘eastern gold zone' to identify structural controls and guide future targeting.²

Full details are contained in the complete announcement, which can be accessed on the ASX website, the investor section of Barton's website, or directly by clicking here.

Commenting on the Tolmer DD assay results, Barton Managing Director Alexander Scanlon said:

"Tolmer's western silver zone is an exciting recent discovery, with broad, high-grade silver supplemented by high-grade gold. Given its clear potential to become a material economic contributor to our regional development strategy, we are systematically building up a data set to enable smart targeting of its potential extensions.

"This drilling has given us a helpful ‘first look' at local structural controls and, together with other recent drilling results and soil sampling data, will help guide future targeting across the Tolmer prospect. We will continue our review, with a focus on the western silver zone, and expect to follow up with further drilling during 2026."

Authorised by the Managing Director of Barton Gold Holdings Limited.
