Untested Anomalies at Coonambula Pose Exploration Risks Despite Promising IP Results
Dart Mining’s recent Induced Polarisation survey reveals a continuous mineralised trend extending over 2km at the Banshee prospect, highlighting significant growth potential at the Coonambula Antimony-Gold project in Queensland.
- IP survey identifies continuous chargeability trend over 2km strike length
- Extension towards historic Lady Mary Antimony mine suggests linked mineralisation
- New off-trend anomalies coincide with gold-antimony soil anomalies, untested by drilling
- Survey co-funded by Queensland Government’s Collaborative Exploration Initiative
- Dart Mining advancing drilling plans and native title agreements to progress project
Survey Highlights New Growth Potential
Dart Mining NL (ASX: DTM) has announced the completion of a detailed Induced Polarisation (IP) geophysical survey over the Banshee mineralised zone within the Coonambula Antimony-Gold-Silver project in Central Queensland. The survey, co-funded by the Queensland Government’s Collaborative Exploration Initiative, has delineated a subtle but continuous chargeability trend with an associated low resistivity zone extending more than 2 kilometres along strike. This finding significantly expands the known mineralised envelope beyond previous drilling limits.
The IP data inversion modelling indicates the Banshee trend extends both east and west from the current drilling area, with the eastern extension interpreted to approach the historic Lady Mary Antimony mine. This suggests the two historic mining areas may be connected along the same mineralised structure, opening the possibility of a larger, continuous mineral system.
New Anomalies Present Untapped Targets
Beyond the main Banshee trend, the survey identified moderate chargeability anomalies immediately north and northeast of the known mineralisation. These off-trend anomalies coincide with gold-antimony soil geochemical anomalies, representing compelling new targets that have yet to be drill tested. Dart Mining has flagged these as priority areas for follow-up exploration, potentially unlocking further resource upside.
While a strong chargeability response was noted in the southern survey area, it is currently interpreted as related to dolerite intrusions and considered of lower exploration interest at this stage.
Building on Strong Historical and Recent Results
The Banshee prospect is one of Central Queensland’s largest historic antimony mining complexes, with production dating back to the late 19th century. Recent drilling by Dart Mining has confirmed high-grade antimony, gold, and silver mineralisation, with assays including up to 32.2% antimony and significant gold and silver grades. These results underpin the prospect’s economic potential and justify the current exploration focus.
Dart Mining is farming into the Coonambula Joint Venture with Great Divide Mining (ASX:GDM) and aims to earn a 51% interest, alongside becoming the joint venture manager. The company plans to integrate the new IP survey results into its ongoing drilling program, including reviewing assays from recent drill holes and finalising native title compensation agreements to facilitate further exploration.
Strategic Outlook and Next Steps
Looking ahead, Dart Mining intends to complete a 4,000-metre drilling program at Coonambula, targeting extensions of the Banshee trend and the newly identified anomalies. Additional desktop studies and spectral analysis are planned for other Queensland projects such as Skarn Ridge, while exploration continues at the Triumph Gold Project and historic mines in Victoria.
The company’s methodical approach, combining geophysical surveys with targeted drilling and government co-funding, positions it well to unlock the full potential of the Coonambula project and its broader Queensland portfolio.
Bottom Line?
Dart Mining’s expanded Banshee trend and fresh targets set the stage for a pivotal drilling campaign that could reshape the Coonambula project’s prospects.
Questions in the middle?
- Will upcoming drilling confirm the continuity between Banshee and Lady Mary mineralisation?
- How significant are the newly identified off-trend chargeability anomalies in terms of resource potential?
- What impact will native title negotiations have on the timing and scope of exploration activities?
