Full Summary

Dart Mining NL has commenced diamond drilling and exploration activities at the Coonambula Antimony-Gold Project located in Central Queensland. The project is a Farm-In Joint Venture agreement with Great Divide Mining (ASX:GDM), with Dart Mining having rights to earn up to 51% interest. The first drill hole (CBADD001) intersected 0.6m of massive sulphide observed to be approximately 70% Stibnite at 42m depth. A second zone of stibnite massive sulphide veining was also intersected at 70m downhole. Assay results are expected to be returned in early November. The Induced Polarisation (IP) Survey commenced in mid-September, with excellent progress made to date. The IP survey is being undertaken in conjunction with the Queensland Government's Collaborative Exploration initiative (CEI) round 9 Funding. Dart Mining intends to drill an initial first phase of 2,000m before the end of the year, with further drilling to be undertaken testing additional targets identified by the IP Survey in early 2026.

Outlook

Dart Mining will continue initial drilling to infill existing high-grade Sb-Au drill intersections at the historical Banshee Mine with the intent of working towards a JORC-compliant resource of antimony-gold at the earliest opportunity. The company will also complete and interpret the IP Survey results, refine the drill plan based on the survey, and generate additional drilling targets.
