Broad, High-Grade Assays Infill Tunkillia 'S1' Pit Area
Rhea-AI Summary
Barton Gold (ASX:BGD / OTCQB:BGDFF) reported first assays from Phase 1 infill drilling at the Tunkillia Gold Project S1 'Starter Pit' on 1 December 2025. New results show broad, high-grade intervals including 14m @ 2.78 g/t, 28m @ 2.60 g/t, 47m @ 2.67 g/t and multiple higher-grade internal zones up to 43.2 g/t. The company cites a modelled average grade 1.19 g/t Au, >200,000 oz recovered in year one and an $825m operating profit in the first year. Remaining assays from Phase 1 are expected in December 2025–January 2026, with an updated JORC (2012) Mineral Resource Estimate targeted by March 2026. The infill campaign aims to convert S1/S2 to Measured/Indicated to support project financing.

Today’s high-grade S1 assay results on 1 Dec 2025 followed with a 5.28% move higher.
Market Pulse Summary
The stock moved +5.3% in the session following this news. A strong positive reaction aligns with prior trading, where high-impact Tunkillia updates have coincided with gains, such as the 12% move on Phase 1 completion and 5.28% on earlier S1 assays. The pre-news setup showed price above the 200-day MA and still 44.12% below the 52-week high, leaving room within the existing range. Investors should weigh the quality of new grades against financing history, including the recent equity raise that saw a 30% drop.

Balance of assays from recent Tunkillia 'Phase 1' upgrade drilling expected during December 2025 and January 2026, with updated JORC (2012) Mineral Resource Estimate by March 2026
ADELAIDE, AU / ACCESS Newswire / December 1, 2025 / Barton Gold Holdings Limited (ASX:BGD)(OTCQB:BGDFF)(FRA:BGD3) ( Barton or Company ) is pleased to announce first assay results from recent drilling at its South Australian Tunkillia Gold Project ( Tunkillia ). These assays confirm broad new intervals of high-grade gold mineralisation which infill the central portion of Tunkillia's S1 'Starter Pit', emphasising the high-value nature of this zone to Tunkillia's development.
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 new Tunkillia assay results, Barton Managing Director Alexander Scanlon said :
"Tunkillia's S1 pit contains the project's highest grade mineralisation, ideally located in a shallower, central zone. Modelling indicates that this will yield over 200,000 gold ounces, generating over
"This early phase of upgrade drilling was therefore designed to further de-risk this profile by infilling higher-grade mineralisation to underwrite project finance. These results very much appear to support that objective, and also highlight the potential for the Tunkillia system to host very high grades within key structural features.
"We expect the balance of Phase 1 infill drilling assays by January, and are targeting the conversion of Tunkillia's 'S1' and 'S2' optimised open pit mineralisation to JORC 'Measured' and 'Indicated' categories by March 2026."
