  • 7m @ 4.59g/t Gold.
  • 8m @ 11.57g/t Silver
  • 8m @ 4.76% Antimony
  • Over 500m of strike length
  • Mineralisation remains open at depth and along strike

Great Divide Mining Ltd (ASX:GDM) was pleased to announce today the completion of a 4,000m drilling program by joint venture partner Dart Mining at the Company’s Banshee Prospect within the Coonambula Project.

GDM CEO Justin Haines said the results continue to validate the Company’s belief that Coonambula hosts a significant gold-antimony system with substantial growth potential.

“Dart Mining (ASX:DTM) have been excellent commercial partners,” said Haines.

“The latest results continue to demonstrate the scale, continuity and multi-metal character of mineralisation at Banshee, with drilling confirming that the high-grade gold-silver-antimony mineralisation remains open both along strike and at depth,” he said.

Dart reported in its’ recent ASX release that the latest drilling has now tested the Banshee lode over more than 500 metres strike length.

Highlights reported by Dart include:

  • 8m @ 1.73g/t gold, 11.57g/t silver and 4.76% antimony from 53.7m (CBADD019), including 0.85m @ 26.66% antimony.
  • 1m @ 1.11g/t gold and 0.5% antimony from 33.0m (CBADD018), including 0.7m @ 4.59g/t gold.
  • 4m @ 2.66g/t gold, 6.44g/t silver and 0.76% antimony from 34.6m (CBADD014), including 0.9m @ 4.34g/t gold, 14.66g/t silver and 2.02% antimony.

“These results represent another important milestone for the Coonambula Project. It is particularly pleasing to see an independent partner continue to report strong gold and antimony intersections while extending the mineralised footprint beyond the historic Banshee workings,” said Haines.

“The latest drilling continues to reinforce our view that Banshee is emerging as one of the more exciting antimony-gold opportunities in Queensland at a time when Antimony has become a strategically important critical mineral globally,” he continued.

“Importantly, these results are being generated through a partner-funded exploration program, allowing GDM to retain significant exposure to exploration success while preserving shareholder capital,” Haines said.

GDM’s Coonambula Project hosts multiple historic gold and antimony workings, including Banshee, Lady Mary and Perseverance, across a highly prospective 5-kilometre mineralised corridor.
