Barton Gold Holdings Boosts Tunkillia Project with Upgraded Resource Estimate

Barton Gold Holdings Limited has announced an upgraded JORC (2012) Mineral Resource Estimate (MRE) for its Tunkillia Gold Project in South Australia. The updated figures exhibit increased gold inventory in several categories while showing a slight decrease across all pit shells. Key highlights include a conversion of 5.27Mt to the Measured category and a 151koz increase in gold inventory classified as Measured & Indicated. This upgrade supports Tunkillia's Optimised Scoping Study (OSS) as a strong foundation for future project finance discussions.

Nearly 58,000 meters of drilling were completed across 520 holes to enhance confidence in mineral resources. Alexander Scanlon, Barton's Managing Director, emphasized the alignment of these results with the May 2025 OSS, reinforcing the project’s economics. The remodelling effort applied a conservative methodology, focusing on economically viable gold resources, affirming the scoping study's robustness as groundwork for a Prefeasibility Study.
