True North Copper Extends Aquila High-Grade Shoot to 300m Depth

Deeper High-Grade Zones Confirmed at Aquila

True North Copper Limited (ASX:TNC) has extended the depth of high-grade copper mineralisation at its Aquila discovery within the Mt Oxide Project by approximately 100 metres, pushing the known northern shoot to around 300 metres below surface. The latest three reverse circulation drillholes intersected broad zones of copper-cobalt-silver mineralisation, highlighted by a 130-metre interval averaging 0.67% copper that includes a six-metre segment grading 5.70% copper. This deep extension bolsters confidence in the continuity and scale of the mineralised system, which remains open at depth.

Broad Mineralised System with High-Grade Shoots

The drilling results at Aquila reveal a well-developed hydrothermal stockwork vein system with a true width estimated between 40 and 60 metres. The mineralisation is hosted predominantly in silicified and hematite-altered siltstone, sandstone, and quartzite units. Distinct higher-grade shoots are embedded within a broader envelope of copper mineralisation, with key intercepts including 74 metres at 0.73% copper and 31 metres at 0.90% copper from other holes. The presence of copper sulphides such as chalcocite, covellite, and bornite in the deeper intervals suggests a robust mineralising system with potential for further high-grade zones.

Strategic Location and Project Scale

Mt Oxide lies within the prolific Mt Isa region of northwest Queensland, approximately 100 kilometres north of the Glencore Copper Smelter and close to 29Metals’ Capricorn Copper Mine. The project hosts multiple resource areas, including the Vero resource and the Aquila discovery, which together define a mineralised system extending about 1.8 kilometres along strike. The northern high-grade shoot tested in the latest drilling spans roughly 250 metres in length and remains open along strike and at depth, indicating significant potential for resource growth.

Ongoing Exploration and Development Plans

True North Copper’s Managing Director Andrew Mooney emphasised the encouraging nature of the results, noting that each drillhole improves understanding of the system's geometry and continuity. The company plans to continue its 2026 drilling program to expand the Aquila system both along strike and at depth, while also advancing regional exploration at nearby targets such as Apollo, Acanthis, Ivena North, and Rhea. Technical studies, including metallurgy and geological modelling, are underway to support the long-term development potential of Mt Oxide.

Three-Platform Growth Strategy Underpins Outlook

These results align with True North Copper’s broader three-platform growth strategy: growing the Mt Oxide resource, developing near-term cashflow at the Cloncurry Copper Project, and pursuing new discoveries across regional targets. The company holds a substantial resource base at Mt Oxide, including 220,000 tonnes of copper, 5 million ounces of silver, and 21,000 tonnes of cobalt in the Vero resource. The ongoing drilling success at Aquila adds to this foundation, potentially enhancing the project's scale and grade profile.

With a steady pipeline of assay results expected in the coming months, True North Copper is methodically unlocking the district-scale potential of Mt Oxide. The confirmation of high-grade mineralisation at depth, beyond the limits of geophysical anomalies, suggests the system could be larger and more complex than previously understood.
