Tartana Minerals has unveiled an expanded 21,000-metre drilling program across its Chillagoe portfolio, targeting a suite of critical and strategic minerals with a focus on resource upgrades and maiden estimates.
- 21,000m drilling planned across 48 highly prospective targets
- Initial 10,000m drilling set to start April 2026
- Queensland Government grants $275,000 for Beefwood copper-gold drilling
- New drill rig acquired to enhance operational flexibility
- Focus on silver, copper, gold, zinc, tin, antimony, tungsten exploration
Expanding the Exploration Horizon
Tartana Minerals Limited (ASX:TAT) is ramping up its exploration efforts with a newly expanded drilling program totalling approximately 21,000 metres across its extensive Chillagoe project portfolio in Queensland. This marks the most active phase in the company’s history, reflecting confidence in the region’s rich endowment of critical and strategic minerals including silver, copper, gold, zinc, tin, antimony, and tungsten.
The program is designed to systematically advance eight key prospects through 82 drill holes, with an initial tranche of 10,000 metres scheduled to commence in April 2026. The company’s Managing Director, Dr Stephen Bartrop, emphasised the strategic advantage of having multiple drill-ready targets clustered closely together, enabling efficient resource allocation and parallel project progression.
Targeting Resource Growth and Maiden Estimates
Among the highlights is the Nightflower project, where a 6,500-metre drilling campaign aims to upgrade the existing silver equivalent exploration target to a maiden JORC 2012 mineral resource estimate. Meanwhile, the Beefwood copper-gold prospect has secured a $275,000 grant from the Queensland Government’s Collaborative Exploration Initiative to fund an 800-metre exploratory hole, marking a significant vote of confidence in the project’s potential.
Other notable projects include the Tartana Mining Leases, where ongoing copper sulphate pentahydrate production is complemented by plans to expand and upgrade a mineral resource estimate currently standing at 45,000 tonnes of contained copper. The Mountain Maid gold project, with inferred resources exceeding 590,000 ounces, is also slated for further drilling to enhance resource confidence and explore associated tellurium and bismuth credits.
Operational Enhancements and Strategic Flexibility
To support this ambitious exploration agenda, Tartana has invested approximately $500,000 in a versatile UDR650 drill rig capable of diamond core, reverse circulation, and air core drilling. Ownership of this rig is expected to improve operational flexibility, reduce costs, and allow the company to respond dynamically to weather and assay turnaround times, a critical advantage given the proximity of its projects around Chillagoe.
The Ok Mines and Bellevue District, a historically significant copper-producing area now consolidated under Tartana’s tenure for the first time since 1901, will also see targeted drilling. This coordinated approach aims to unlock value from a cluster of satellite deposits with promising mineralised gossans and open-ended mineralisation at depth.
A Portfolio Poised for Value Creation
Tartana’s comprehensive exploration strategy balances the pursuit of new discoveries with the advancement of existing resources. With 48 highly prospective targets identified; 32 of which have prior drilling history warranting further work; the company is positioning itself to deliver multiple value-creating catalysts throughout 2026 and beyond. The combination of government support, operational enhancements, and a diversified commodity focus underscores Tartana’s commitment to unlocking the full potential of its Chillagoe assets.
Bottom Line?
As drilling kicks off, Tartana’s ability to convert targets into resources will be pivotal in shaping its growth trajectory and market standing.
Questions in the middle?
- How will assay results from the initial 10,000m drilling influence Tartana’s resource estimates and project prioritisation?
- What impact will ownership of the new drill rig have on exploration costs and timelines compared to previous campaigns?
- Can Tartana leverage its diversified portfolio to mitigate commodity price risks amid evolving market conditions?
