Could Banshee’s New High-Grade Gold Assays Transform Dart Mining’s Prospects?
Dart Mining has reported its highest gold assay results to date from the Banshee antimony-gold mine in Queensland, revealing promising mineralisation that could signal a significant gold-rich system. The ongoing drilling program and forthcoming assays are set to further define the project's potential.
- Record gold assay of 18.30 g/t Au over 0.5m at Banshee mine
- Multiple gold and antimony intersections confirming mineralisation continuity
- Drill hole CBADD002 extends mineralised zones over 200m from Banshee Pit
- Ongoing diamond drilling with assays expected through early 2026
- Plans to integrate IP survey results and develop a JORC resource
Record-Breaking Assays at Banshee
Dart Mining NL (ASX – DTM) has announced a milestone in its exploration campaign at the Banshee antimony-gold mine, part of the Coonambula project in Central Queensland. Drill hole CBADD002 delivered the highest gold assay recorded at the site to date, with a standout intercept of 0.5 metres grading 18.30 grams per tonne (g/t) gold from 184.5 metres depth. This result surpasses previous highs and underscores the potential for a substantial gold system beneath the historic antimony workings.
Expanding Mineralisation and Geological Insights
The assays from CBADD002 reveal a complex mineralised system where gold and antimony coexist within quartz and stibnite veins, often accompanied by sericite alteration. Notably, broader gold zones contain highly mineralised stibnite veins, reinforcing earlier findings from drill hole CBADD001. The presence of a thick gold mineralised hydrothermal breccia at the base of CBADD002 hints at a deeper, potentially more extensive gold-rich system that Dart Mining aims to delineate further.
Strategic JV and Ongoing Exploration
The Coonambula project is operated under a farm-in joint venture with Great Divide Mining (ASX – GDM), leveraging combined expertise to unlock value from this historically productive region. Dart Mining has completed over 1,350 metres of diamond drilling across 11 holes, with assays from CBADD001 and CBADD002 received and more expected in batches through early 2026. The company is also integrating geophysical data, including induced polarization (IP) surveys, to refine drilling targets and better understand the mineralisation controls.
Historical Context and Regional Potential
Banshee is one of Central Queensland's largest historic antimony mining complexes, with production dating back to the late 19th century. The project area hosts multiple prospects along a 5-kilometre strike, including the Lady Mary prospect to the east. Previous exploration has identified high-grade antimony and gold mineralisation, and Dart Mining's recent results build on this foundation, suggesting the potential for a significant intrusion-related gold system akin to other notable deposits in the New England Fold Belt.
Next Steps and Market Implications
Dart Mining plans to continue its methodical exploration approach, completing the current drilling program, interpreting IP survey results, and advancing towards a maiden JORC resource estimate. The company is particularly interested in testing whether the gold mineralisation extends closer to surface, which could enhance the project's economic prospects. Investors will be watching closely as further assay results and geological models emerge in early 2026, potentially reshaping the valuation and strategic outlook for the Coonambula project.
Bottom Line?
With record gold grades confirming a robust mineralised system, Dart Mining’s next assays and resource modeling will be pivotal for Coonambula’s future.
Questions in the middle?
- Will the upcoming assays confirm extensions of the high-grade gold zones near surface?
- How might the integration of IP survey data refine the understanding of mineralisation controls?
- What timeline is Dart Mining targeting for a formal JORC resource declaration?
