Triumph Gold Drilling Hits 1,637m with Nine New Mineralised Zones

Drilling Progress and New Discoveries

Dart Mining NL has reported significant progress in its ongoing diamond drilling program at the Triumph Gold Project in Queensland. The company has completed 1,637 metres of drilling across 10 holes, focusing on the New Constitution and South Constitution prospects, which are key components of the existing Inferred Mineral Resource Estimate. While assay results are still pending, the initial geological logging has identified nine new zones of sulphide mineralisation, suggesting the potential for resource expansion.

Structural Insights and Mineralisation Highlights

The drilling has provided valuable structural orientation data, confirming key geological controls on mineralisation. Notably, one drill hole (TRDD006) intersected strong alteration and veining with visual estimates of up to 15% arsenopyrite, alongside other sulphides such as pyrite and sphalerite. These findings indicate mineralisation extending beyond the boundaries of the current resource, which could enhance the project's economic prospects by adding mineralised zones within a potential mining pit envelope without increasing waste.

Operational Improvements Amid Weather Challenges

Despite increased rainfall in the Gladstone region, Dart Mining has improved its drilling efficiency, achieving a peak shift record of 48 metres drilled in a single day. The company attributes this to better logistical planning, earthworks access, and the establishment of balanced back-to-back drill crews. These operational gains are expected to continue as the team finalises camp and laydown areas, further accelerating the drilling program.

Next Steps and Exploration Outlook

Dart Mining plans to continue its diamond drilling campaign to expand the existing resources both along strike and at depth. The company also intends to undertake broader regional exploration targeting bulk tonnage deposits and to identify additional prospective zones within the Triumph project area. The upcoming assay results, expected by the end of June 2025, will be critical in validating the visual mineralisation observations and guiding future resource updates.

Strategic Significance

This drilling update marks an important milestone for Dart Mining as it seeks to unlock the full potential of the Triumph Gold Project. The discovery of new sulphide zones and confirmation of structural controls not only support the existing resource base but also open avenues for resource growth. The company’s methodical approach to exploration and operational efficiency improvements position it well to advance the project towards development.
