Barton Gold ~~Completes~~ Tunkillia ~~Phase-2~~ Project Drilling and Approvals

Barton Gold has completed its Phase-2 reverse-circulation and diamond drilling programme at the Tunkillia gold project in South Australia. The campaign added 38,760 m across 311 holes, bringing the total drilling for the resource upgrade effort to 57,653 m across 520 holes when combined with Phase 1. During the final stages of the program in late July 2026, assay results included a 29-metre interval grading 1.24 g/t Au (with 4 m at 4.08 g/t) and a 19-metre interval grading 1.34 g/t Au. Managing Director Alex Scanlon stated that results “generally exceeded expectations, with positive surprises in some zones offering material upside potential.” The drilling has infilled high-value pits and identified broader, higher-grade extensions in Area 51. In late August 2026, the company confirmed new high-grade gold mineralisation from the Phase 2 campaign, identifying significant intercepts within shallow zones of existing starter pit outlines. Notable results include 6 metres at 6.61 g/t Au (featuring a 1-metre interval of 32.4 g/t Au) and 11 metres at 2.87 g/t Au (including 1 metre at 10.6 g/t Au). These findings are expected to support mineralisation extensions and enhance the grade profile for the upcoming pre-feasibility study (PFS). In early September 2026, the South Australian Department for Energy & Mining (DEM) approved the environmental Scoping Report for the Tunkillia Gold Project. This approval establishes the official terms of reference for the project’s development approvals process and is a primary step toward securing a Mining Lease (ML). The approved report defines the environmental studies, modeling, and community engagement programs required for future approvals. Following the resource upgrade drilling, Barton Gold has commenced a sterilisation drilling program to test potential locations for critical ~~infrastructure, such as processing plants and tailings storage facilities, to ensure they do not overlap with valuable mineralisation.~~ infrastructure. The company is also conducting environmental, cultural heritage, and renewable energy ~~evaluations to support project financing and mining lease applications.
