Updated gold and silver JORC Mineral Resource Estimates (MRE) to follow, with PFS targeted for Q1 CY27 delivery to support Mining Lease application thereafter
Barton Gold Holdings Limited (ASX:BGD)(OTC:BGDFF)(FRA:BGD3) (Barton or Company) is pleased to announce the final assays from 'Phase 2' upgrade drilling at its South Australian Tunkillia Gold Project (Tunkillia).
Broad, high-grade assays continue to infill Tunkillia's 'Starter Pits', reinforcing the central high-grade zone driving early project economics, and highlighting the potential for new high-grade mineralisation.
A total of 57,653m was drilled across 520 RC and DD holes during 'Phase 1' and 'Phase 2' upgrade drilling, with 'Phase 2' comprising 38,760m across 311 holes. With all 'Phase 2' assays now received, Barton has prepared representative cross-sections of 'Phase 2' results for the 'Area 51', '223 North' and 'Area 223' optimised open pit areas from its May 2025 Optimised Scoping Study (OSS).
Full details can be accessed in the complete announcement on the ASX website or directly by clicking here.
Commenting on the 'Phase 2' Tunkillia assay results, Barton Managing Director Alexander Scanlon said:
"We are pleased with the results of Tunkillia's 'Phase 2' infill assays, which support the highest-grade results of 'Phase 1' drilling and the potential for new, shallower zones of high-grade mineralisation within the existing 'Starter Pits'.
"We are now remodelling all Tunkillia mineralisation with the benefit of nearly 58,000m additional drilling since last year. A JORC Resources update for gold is pending, and a JORC update for silver and a PFS are planned for Q1 CY27."
