Further Assays Infill Tunkillia Pit Extension Targets
Rhea-AI Summary
Barton Gold (OTCQB:BGDFF) reported further assays from its ~40,000m 'Phase 2' reverse circulation drilling at the Tunkillia Gold Project in South Australia, infilling the Area 223 North and southern main Area 223 optimised open pits. Significant intersections include 29m @ 1.24 g/t Au from 48m (including 4m @ 4.08 g/t Au) and 19m @ 1.34 g/t Au from 149m (including 4m @ 2.85 g/t Au).
The company said Phase 1 and 2 results have infilled the highest value S1/S2 pits and identified broader, higher-grade Area 51 extensions. A Pre-Feasibility Study for Tunkillia, led by GR Engineering, is underway and targeted for completion in Q1 CY27, with Barton anticipating future Mineral Resource upgrades for gold and silver.

'Phase 1' and 'Phase 2' assays to-date have infilled highest value S1 / S2 pits (Area 223) and southern Area 223 with high-grade intersections and identified broader and higher-grade Area 51 extensions(1)
Tunkillia Pre-Feasibility Study (PFS) underway led by GR Engineering (GRES), targeting Q1 CY27 completion to accommodate expanded drilling and prospective Minerals Resources upside in study(2)
Barton Gold Holdings Limited (ASX:BGD)(OTCQB:BGDFF)(FRA:BGD3) (Barton or Company) is pleased to announce the further assays from 'Phase 2' upgrade drilling at its South Australian Tunkillia Gold Project (Tunkillia). These come from Area 223 North and the southern zone of the main 'Area 223' optimised open pit. These assays include broad intersections which further infill the currently modelled Area 223 mineralisation.
Further assays will continue to be reported from this area in due course, with the recently expanded Tunkillia drilling program targeting further extensions and higher-grade mineralisation upside.(3) After all results have been received Barton will then prepare comprehensive and representative cross sections of assay results.
Full details can be accessed in the complete announcement on the ASX website or directly by clicking here.
Commenting on the new Tunkillia assay results, Barton Managing Director Alexander Scanlon said:
"Tunkillia continues to deliver confirmation of broad mineralisation in key target areas, with assays to-date identifying new and higher-grade mineralisation which supports potential quantity and grade improvements in multiple zones.
"We are nearing completion of expanded 'Phase 2' upgrade drilling programs, with a large number of assays pending. We look forward to completing these programs in the near future, following which we anticipate Mineral Resources upgrades for both gold and silver, the completion of our PFS, and the submission of our Mining Lease application."
