Highlights
- Dart Mining explores high-grade antimony alongside gold projects
- Coonambula project shows strong mineralisation potential
- Exploration strategy targets multiple Australian regions
Dart Mining (ASX:DTM), widely recognised for its gold exploration, is also building a strong position in antimony — a critical mineral now drawing increased global attention. While not part of the ASX 200, the company’s approach reflects a broader trend toward diversifying exploration portfolios to align with future-facing industries.
Antimony’s value extends beyond its traditional use in hardening metals. It plays a role in electronics, renewable energy technologies, flame retardants, and solar panel manufacturing, where it can enhance efficiency. The growing focus on strategic minerals is supported by rising defence spending and expanding renewable energy infrastructure worldwide.
Coonambula’s Strategic Potential
Advancing Resource Definition
Dart’s Coonambula project in Queensland is central to its antimony strategy. The site hosts high-grade mineralisation and includes the historical Banshee Antimony Mine. Early exploration results indicate notable mineral zones, and the company plans further drilling to define a JORC-compliant resource for both antimony and gold. Modern exploration techniques, supported by a government grant, will help refine drill targets and potentially extend known mineralisation.
Strength in Portfolio Diversity
Beyond Coonambula, Dart’s antimony presence is spread across its Rushworth project in Victoria and Triumph in Queensland. Rushworth is strategically located near Australia’s only current producing antimony mine, while Triumph contains historical workings with similarities to larger-scale deposits in the region. This multi-project approach offers opportunities for scale, continuity, and operational flexibility.
A History of Antimony Exploration
While the renewed interest in antimony is relatively recent, Dart’s connection with the mineral stretches back years. Historical sites like Tallandoon and Sandy Creek in Victoria once produced significant quantities of both gold and antimony. These legacy assets give the company a foundation of geological knowledge and exploration data that informs current work programs.
With in-house drilling capabilities, Dart can maintain exploration momentum without the constraints of external contractors, enabling more extensive testing and faster project progression.
