Tunkillia Gold Project Upgrade
Barton Gold confirms new high-grade mineralisation at its South Australian Tunkillia project.

Barton Gold Holdings has found rich gold deposits in shallow areas at its Tunkillia project in South Australia. Market Screener reported that Phase 2 drilling results confirm high-grade mineralisation within the company's planned 'Starter Pits' — the first mining areas to be developed. These findings could boost the project's early profit potential and increase gold reserves ahead of a planned feasibility study.
The discovery supports expanding total mineralisation estimates and improving the grade profile — how much gold sits in the rock — for Barton's upcoming prefeasibility study. Mining Hub noted that more Phase 2 assay results are expected soon. The company says no new information would materially change its exploration forecasts or financial projections.
Phase 2 Drilling Targets Starter Pit Economics
Barton's Phase 2 upgrade drilling focused on infill work within shallow zones of existing pit outlines. The goal was simple: find more gold closer to the surface where it costs less to mine. Barton Gold confirmed that results show significant high-grade mineralisation in these target areas, improving the project's near-term mining profile.
Resource Expansion Could Lift Production Potential
The drilling success means Barton may increase its official JORC Mineral Resources — the industry standard for measuring ore reserves. Higher resource numbers within the May 2025 pit outlines improve the project's early viability. Yahoo Finance highlighted that confirming high-grade mineralisation in Starter Pits could significantly boost initial operating economics and cash generation.
An upgraded grade profile makes mining more profitable. Even small jumps in average gold content per tonne can change project returns. The Phase 2 results feed directly into Barton's prefeasibility study, which models the full project economics and funding requirements.
Final Assay Batch Expected Shortly
Barton confirmed that a final batch of Phase 2 assays is pending. These results will complete the drill campaign and provide the full picture of shallow high-grade zones. Newswire noted the company maintains confidence in exploration projections and has found no new data that would materially alter its financial forecasts for the project.
