Dart Mining’s TRDD014 Drill Hole Reveals 110m Widening of Gold System

Expanding the Gold Footprint

Dart Mining NL has announced encouraging results from its recent deep diamond drilling campaign at the Triumph Gold Project in Central Queensland. The company completed 17 drill holes totalling 2,761 metres, focusing on the New Constitution, South Constitution, and Big Hans prospects. The highlight is drill hole TRDD014, which returned multiple high-grade gold and silver intercepts, confirming that the New Constitution orebody is significantly wider and extends deeper than previously understood.

The assays reveal a 110-metre eastward widening of the gold system, with discrete high-grade zones including 0.5 metres grading 28.20 g/t gold and 121 g/t silver at 56.4 metres depth, and 0.5 metres at 24.60 g/t gold and 74 g/t silver at 233.7 metres. These results underscore the presence of parallel lodes and broad mineralised zones that had not been fully delineated before.

Implications for Resource and Economics

The Triumph Gold Project currently holds an Inferred Mineral Resource of 2.16 million tonnes at 2.17 g/t gold, equating to approximately 150,000 ounces of gold. Dart recently outlined an Exploration Target ranging from 5.1 to 7.6 million tonnes at 1.72 to 2.52 g/t gold, suggesting potential for a resource increase to between 285,100 and 613,200 ounces. The new drilling results, particularly the discovery of additional parallel lodes and the extension of mineralisation at depth, could materially enhance future resource estimates.

Moreover, the presence of stacked lodes and broader mineralised zones may improve the strip ratio in any future open-pit mining scenario, potentially boosting the project’s economic viability. Dart’s Chairman, James Chirnside, highlighted the significance of these findings, noting the open nature of mineralisation and the abundance of new target areas for ongoing exploration.

Geological Context and Exploration Strategy

The gold mineralisation at Triumph is hosted within quartz-sulphide veins associated with pyrite and arsenopyrite, typical of intrusion-related gold systems. The project lies within the Norton Tonalite intrusive complex, with mineralisation controlled by fault structures and multiple phases of alteration. Dart’s exploration approach includes reviewing geophysical data to identify new targets, drilling deeper beneath known corridors, and expanding resource footprints along strike and at depth.

In addition to the Southern Mineralised Corridor, which includes New Constitution and Big Hans, Dart is also targeting the Northern Mineralised Corridor around Bald Hill and the historic Advance mine area. Both corridors show strong geophysical anomalies and historic high-grade intercepts, offering promising avenues for resource growth.

Next Steps and Broader Ambitions

Dart plans to continue diamond drilling to expand resources and test new targets identified through geophysical surveys. Regional exploration will also focus on bulk tonnage targets and deeper mineralisation. Beyond Triumph, Dart is advancing its Coonambula antimony-gold project and refocusing Victorian exploration efforts around the Rushworth Goldfield, aiming to build a strong regional presence in Queensland and Central Victoria.

With the deep drilling phase complete and assay results confirming wider and deeper mineralisation, Dart Mining is well positioned to advance the Triumph Gold Project towards a more robust resource base and improved economic outlook.
