High-Grade Banshee Results Boost Dart Mining’s Resource Ambitions Amid Open Mineralisation

Record-Breaking Drill Results

Dart Mining NL (ASX: DTM) has unveiled its latest diamond drilling assay results from the Banshee prospect within the Coonambula Antimony-Gold Project in Central Queensland. The company reported record high grades for gold, silver, and antimony, surpassing previous intercepts and highlighting the prospect’s growing potential.

Notably, drill hole CBADD010 returned a standout gold intercept of 0.2 metres at 20.20 grams per tonne (g/t) from 37.7 metres depth, eclipsing the prior best of 18.30 g/t Au from CBADD002. This hole also delivered a remarkable antimony grade of 44.6% over 0.6 metres, underscoring the high-grade nature of the mineralisation. Meanwhile, CBADD004 yielded an exceptional silver intercept of 0.6 metres at 234 g/t, equivalent to over eight ounces per tonne, reinforcing the polymetallic character of the system.

Expanding Mineralisation and Open Potential

These results extend the strike length of mineralisation at Banshee to more than 320 metres, with both east and west zones remaining open for further expansion. Importantly, mineralisation is confirmed near surface and at depth, including within the oxidation zone less than 10 metres from the surface. This continuity and vertical extent bode well for future resource development.

Dart Mining’s Chairman, James Chirnside, expressed optimism about the drilling outcomes, noting the confidence growing in the continuity of mineralisation and the encouraging shallow extensions that could feed into a maiden Mineral Resource Estimate (MRE). The company is progressing a 4,000-metre drilling program as part of its farm-in joint venture with Great Divide Mining (ASX: GDM), aiming to earn a 51% interest in the project.

Towards a Maiden Resource and Economic Studies

Alongside drilling, Dart Mining is initiating metallurgical test work to better understand recovery factors and to develop a conceptual processing flowsheet. While processing options remain under evaluation, these studies are critical to underpinning the reasonable prospects for eventual economic extraction (RPEEE) required for the MRE.

The company also plans to address historical mining depletion near the Banshee mine, where a void was intersected at 27 metres below surface in drill hole CBADD018. Understanding past mining impacts will be important for accurate resource modelling.

Geological Context and Exploration Outlook

The Banshee prospect is part of a broader polymetallic system hosted within granodiorite intrusions of the New England Orogen, sharing geological similarities with known antimony-gold deposits such as Hillgrove and Costerfield. The mineralisation is characterised by stibnite-bearing quartz veins with associated gold and silver enrichment.

Dart Mining’s exploration strategy includes expanding the strike and depth of mineralisation, refining geological models, and leveraging analogues to unlock further potential. The company is also advancing exploration at other Queensland projects, including Skarn Ridge and Triumph.
