Star Minerals Limited announces breakthrough shallow gold drill results at the Tumblegum South Gold Project. High-grade near-surface intersections reinforce the resource model as the firm moves toward mining approvals and production, with additional assay results expected shortly.
Star Minerals Limited has reported impressive assay results from its Tumblegum South Gold Project following a 2,032‐metre reverse circulation drilling program consisting of 38 holes. Results from 22 drill holes have been returned, with standout measurements such as a 5‐metre intercept at 30.91 g/t gold from 21 metres, which included 2 metres at 75.45 g/t gold. Other notable intercepts include a 5‐metre section at 10.85 g/t gold from 5 metres (with 2 metres at 25.65 g/t gold), a 7‐metre segment at 3.28 g/t gold from 28 metres (including 1 metre at 13.40 g/t gold) and various additional intercepts demonstrating strong near-surface mineralisation.
The drilling campaign focused on infill work along the shallow portions of the deposit using a dense 12.5m x 12.5m grid to enhance confidence in the geological continuity and mineral resource calculations. These results not only validate the existing geological model but also support plans for an updated JORC Mineral Resource estimate expected later this year. The Company is also advancing exploration and sterilisation drilling on the periphery, with additional assays expected in the coming fortnight. With a clear path toward mine approval submissions and a mine development agreement being finalised with MEGA Resources, these developments underpin the Company’s efforts to bring this high-quality gold deposit into production as early as 2026.
Technical indicators from the drilling results, including multiple high-grade intercepts and systematic sampling protocols, confirm that the deposit benefits from near-surface mineralisation with minimal barren overburden. The dense sampling grid and consistent assay results lend confidence to the geological model, which is in line with previous resource updates. Updated production targets suggest the project could produce between 11.8 and 15.9 thousand ounces of gold from a resource ranging from approximately 337 kt indicated and 279 kt inferred at an overall grade of around 2.28 g/t.
Bullish sentiment is supported by the strong quality of the infill drilling results, which enhance the resource model and support the Company’s timetable for production. The strategic partnerships, progress in mining approvals, and robust project economics across a range of gold prices further strengthen the outlook. On the other hand, bearish concerns may focus on the pending additional drill results, which could require adjustments to the resource estimate, and the challenges of transitioning from exploration to production along with associated capital requirements. Overall, the technical indicators and operational progress provide a positive signal for the Company’s roadmap towards production.
