PRESS RELEASE: Geophysics Confirms Increasing Scale at GDM’s Coonambula Antimony–Gold Project

Great Divide Mining Ltd (ASX:GDM) has welcomed strong geophysical results from the Banshee Prospect at its’ Coonambula Antimony–Gold Project in Central Queensland, confirming strike extension and identifying new priority drill targets.

An Induced Polarisation (IP) survey, completed by Joint Venture partner Dart Mining NL and co-funded under the Queensland Government’s Collaborative Exploration Initiative (CEI), has delineated a continuous east–west chargeability trend extending beyond the currently drilled Banshee mineralisation envelope.

Modelling indicates the structure continues for more than one kilometre within the surveyed grid and remains open. Importantly, the eastern anomaly trends toward the historic Lady Mary antimony workings approximately 900 metres along strike, reinforcing the potential for both areas to sit within the same mineralised corridor.

In addition, previously untested chargeability anomalies have been identified north of the main Banshee trend. These coincide with established gold–antimony soil anomalism and will form part of upcoming drill planning.

GDM CEO Justin Haines said the results represent an important step in systematically unlocking the scale of the Coonambula system.

“The IP survey provides independent confirmation that the Banshee structure extends well beyond the area drilled to date,” said Haines.

“The possible structural linkage between Banshee and Lady Mary points to a much broader mineralised corridor than has previously been defined,” he continued.

“Equally encouraging are the northern anomalies, which remain undrilled and coincide with gold–antimony geochemistry. This is exactly how we approach exploration — methodically building the geological picture, then advancing high-confidence targets,” said Haines.

Coonambula hosts a series of historic high-grade antimony workings, including Banshee and Lady Mary, within a prospective five-kilometre east–west structural zone. The project sits within Queensland’s New England Orogen and exhibits geological similarities to established antimony–gold systems such as Hillgrove in NSW.

Under the Farm-In Joint Venture, Dart Mining can earn up to a 51% interest in the project by funding exploration. The latest IP results will now be incorporated into an ongoing 4,000-metre drilling programme.

“GDM continues to advance Coonambula in a disciplined “crawl-walk-run” approach — combining historical data, geochemistry, geophysics and drilling to define the full scale of this emerging antimony–gold system,” added GDM’s Chairman, Paul Ryan.
