True North Copper’s latest diamond drilling at Mt Oxide validates the Aquila discovery as a broad, continuous copper-cobalt-silver system with well-defined higher-grade zones, extending mineralisation over 1.8km strike and reinforcing its standalone development potential.
- Diamond drilling confirms broad mineralised system at Aquila
- Key intercepts include 35m at 0.82% Cu and 32m at 0.70% Cu
- Acanthis trend extended by 250m, supporting district-scale potential
- Ongoing 2026 program to deliver further assay results and expand targets
- Three-platform growth strategy underpins Mt Oxide and Cloncurry projects
Drilling Validates Aquila as a Large-Scale Copper System
True North Copper (ASX:TNC) has delivered a significant vote of confidence in its Mt Oxide Project with assay results from the first three diamond drillholes of its 2026 program at the Aquila Copper-Cobalt-Silver Discovery. The drilling confirms a broad, continuous mineralised system extending over approximately 1.8 kilometres of strike, featuring well-developed higher-grade zones that validate the company’s geological model.
The standout intersections include 35 metres at 0.82% copper, 0.04% cobalt, and 3.4 grams per tonne (g/t) silver from 32 metres depth, which contains a high-grade core of 9.2 metres at 2.21% copper. Another hole returned 32 metres at 0.70% copper, 0.06% cobalt, and 7.2 g/t silver from 181 metres, including a 9.4-metre zone grading 2.04% copper. A third hole intersected 36 metres at 0.34% copper, 0.09% cobalt, and 1.5 g/t silver from 136 metres, confirming the eastern extent of the system. These results underpin the emerging scale and continuity of the Aquila mineral system, which appears to be a robust stockwork to sheeted vein system rather than narrow vein-style mineralisation.
Extension of the Acanthis Trend and Broader Mineralised Corridor
Beyond Aquila itself, drilling at Mt Oxide has extended the parallel Acanthis trend by 250 metres to approximately 500 metres strike. Though the Acanthis intercepts are more subdued, the structural, alteration, and mineralisation styles closely resemble those at Aquila, suggesting a genetically related mineralised corridor. This potential for multiple related mineralised structures enhances the district-scale prospectivity of the Mt Oxide Project.
True North’s Managing Director Andrew Mooney highlighted that these results represent an important step toward developing Mt Oxide into a standalone copper operation. He emphasised the improved geological understanding gained from the drilling, which is critical for targeting future exploration and expanding the mineral system.
Ongoing Drilling and Exploration Pipeline
The 2026 drilling campaign is far from complete, with further assay results pending from multiple drillholes and target areas including Aquila North, Apollo, and Acanthis. The company plans to continue expanding the Aquila mineral system, refine its geological model, and advance technical studies such as metallurgy and geological modelling to support long-term development.
Regional exploration remains a priority, with targets like Apollo, Acanthis, Ivena North, and Rhea identified as prospective for additional copper-cobalt-silver discoveries. This integrated approach combines geological mapping, geochemistry, and geophysics, reflecting a systematic search for a district-scale copper system within the world-class Mt Isa region.
Three-Platform Growth Strategy Anchors Company Outlook
True North is executing a three-pronged strategy: growing the Mt Oxide resource through discovery and drilling; developing near-term cash flow from its Cloncurry Copper Project; and pursuing regional exploration for Tier-1 IOCG systems. The Mt Oxide Project, highlighted by the Aquila discovery and the Vero resource, is positioned as a potential standalone copper-silver-cobalt development asset, while Cloncurry aims to deliver near-term revenue.
The company’s recent focus on the Mt Oxide Project builds on its prior announcements that have steadily expanded the known strike length and resource confidence. The detailed geological logging, rigorous QAQC procedures, and use of modern exploration techniques underpin the reliability of these results.
While the true widths of mineralisation remain to be fully defined due to drill orientation complexities, the consistent broad intercepts across multiple holes support continuity at system scale. The next phases of drilling and technical studies will be critical to unlocking the full economic potential of Mt Oxide.
Bottom Line?
True North Copper’s 2026 drilling confirms Aquila as a robust, district-scale copper system, setting the stage for a potentially transformative standalone development at Mt Oxide.
Questions in the middle?
- How will upcoming assay results from Aquila North, Apollo, and Acanthis influence the overall resource model?
- What metallurgical characteristics will the mineralisation exhibit, and how might this impact processing strategies?
- Can True North replicate the scale and grade of nearby Capricorn Copper to justify standalone development?
