• Final round of 'phase 1' Resource upgrade drill results return shallow high-grade assays in Tunkillia S1 / S2 optimised pits
• Tunkillia 'S1' and 'S2' pits modelled to produce $1.3 billion operating profit in the first 2.5 years of operations
• 2026 development drilling programs, including water bore drilling, 'Phase 2' upgrade drilling, and metallurgical / geotechnical diamond drilling expected to start during late January

Barton Gold Holdings Limited (ASX:BGD, OTCQB:BGDFF, FRA:BGD3) is pleased to announce final Phase 1 upgrade drilling assays from its South Australian Tunkillia Gold Project. These assays infill the S2 pit area with shallow, high-grade intersections, and provide further insights for optimisation of the geological model, including potential reinterpretation of shallow mineralised zones to favour vertically-controlled mineralisation instead of broader flat lying oxide and transitional zones. The new assay results follow two batches of recently reported assays from the high value 'S1' pit area, which included several broad high-grade intersections. The latest assays indicate further support for re-modelling of this mineralisation to favour a more vertically oriented interpretation, as opposed to flat lying 'supergene' style mineralisation. The Tunkillia 'S1' and 'S2' pits are modelled to yield 365koz Au and A$1.3bn operating cash during the first 2.5 years of operations. 2026 development drilling programs, which include water bore drilling, 'Phase 2' MRE upgrade drilling, and metallurgical and geotechnical diamond drilling, are expected to commence later this month to support JORC MRE classification upgrades, a pre-feasibility study, and a Mining Lease application by the end of 2026.
