Barton Gold Holdings Limited - Tunkillia infill drilling confirms new high-grade mineralisation within shallow zone of existing high-value 'Starter Pit' outlines

About this update from Barton Gold Holdings Limited

Barton Gold Holdings Limited (ASX: BGD, OTC: BGDFF, FRA: BGD3) (Barton or Company) is pleased to announce further assays from 'Phase 2' upgrade drilling at its South Australian Tunkillia Gold Project (Tunkillia). These include broad, high-grade assays in shallow areas of Tunkillia's 'Starter Pits', supporting potential to extend total Tunkillia mineralisation, increase JORC Mineral Resources within existing May 2025 OSS optimised pit outlines, and increase the grade profile of this mineralisation in Tunkillia's upcoming PFS. A final batch of 'Phase 2' Resource upgrade drilling assays is expected to be reported shortly. After all results have been received Barton will then prepare comprehensive and representative cross sections of assay results. Commenting on the new Tunkillia assay results, Barton Managing Director Alexander Scanlon said: 'Tunkillia's 'Phase 2' drilling was expanded after early analysis of infill assays identified a potential new domain of high-grade mineralisation within its 'Starter Pit' outlines. These 'S1' and 'S2' pits drive Tunkillia's robust economics, and are modelled to yield a A$1.8bn operating profit during the first 2.5 years alone at current gold and silver prices. 'Given that the average grade driving these economics in the 'Starter Pits' is 1.05 g/t Au, the new assays are exceptional. Such mineralisation could materially boost Tunkillia's already remarkable early operating economics. We are very much looking forward to the balance of outstanding assay results, the majority of which are targeting this potential. 'We expect to report one final batch of assays shortly, and look forward to sharing Mineral Resources upgrades for both gold and silver in the coming months before completing our PFS and submitting our Mining Lease application.'
