Great Divide Mining (ASX:GDM) has welcomed a further round of strong visual drilling results from its’ farm-in partner Dart Mining NL (ASX:DTM), with every diamond hole at the Coonambula Antimony–Gold Project intersecting visible stibnite across the Banshee Prospect.
“Dart has now completed over 1,350 metres of drilling, confirming a continuous 300-metre mineralised strike that remains open both along trend and at depth,” said GDM’s CEO Justin Haines.
“Importantly, multiple intervals of solid to massive stibnite continue to reinforce the scale and persistence of the system,” he went on.
Recent visual results include:
- 0.5m of solid stibnite within a 2.2m mineralised interval in CBADD010.
- 1.1m of quartz-veined stibnite, including two solid veins, in CBADD006.
- 7.4m sulphide zone with massive stibnite logged in CBADD004.
- Massive stibnite zones in CBADD005/005a and CBADD007.
“The consistency of the drilling results highlights the growing scale of the Banshee system,” said Haines.
“Antimony is a globally recognised critical mineral, and Coonambula just keeps delivering. When every drill hole hits stibnite — and several contain massive zones — you know you’re working on a system with real scale,” he said.
Core processing and sampling at the site are now well progressed, with Dart preparing material for laboratory analysis. Drilling is continuing to tighten structural interpretation, define thickness, and extend the broader Sb–Au system across the Banshee trend.
“Dart’s field team continues to impress making rapid, smart progress, and we’re increasingly confident about the potential for a future resource,” said Haines, “confirming GDM’s brown-field strategy.”

Dart Mining NL (ASX:DTM)
The Triumph Gold Project is Dart’s first step into an advanced intrusion related gold system project in Queensland. Dart will look to develop a regional presence in Queensland through advanced stage intrusion related and epithermal gold projects. Dart is farming into the Coonambula Antimony-Gold Project in Central Queensland. Dart Mining will continue to evaluate several historic goldfields in Central and Northeast Victoria including the Rushworth Goldfield and the new porphyry and lithium province in Northeast Victoria identified by Dart. The area is prospective for precious, base, and strategic metals. Dart Mining has built a strategic and highly prospective gold exploration portfolio in Central and Northeast regions of Victoria, where historic surface and alluvial gold mining indicates the existence of potentially large gold endowment.
