True North Copper Limited has announced a breakthrough exploration result from its Mt Oxide Project in northwest Queensland with the discovery of a large-scale, high‐grade copper–cobalt–silver mineralised system at the Aquila Prospect. The company’s reverse circulation drilling, which began in mid-May 2025, has now completed three of five targeted holes at Aquila – a prospect located more than 4 kilometres northeast of its existing resource. The early assay results reveal significant mineralisation intervals, with two distinct zones in hole MOX233 showing an upper intercept of 30 metres grading 2.45% copper and 6.2 g/t silver, including sub-intervals of over 10 metres at more than 5% copper, and a lower zone of 98 metres averaging 0.61% copper. Hole MOX232 provided broad, near-surface mineralisation over 145 metres at 0.75% copper with high-grade sub-zones yielding up to 5.17% copper over very short intervals, while MOX231 confirmed deep system continuity with a 34-metre intercept at 0.71% copper and a notable 1-m interval reaching 4.68% copper. The technical details underscore the prospect’s promising scale, with the mineralisation remaining open both along strike and at depth. Industry-standard assay cutoffs—ranging from 0.1% to 3.0% copper with internal dilution criteria—were applied to these intercepts, reinforcing the robustness of the findings. This discovery mirrors the geological patterns observed at the company’s nearby Vero deposit, suggesting that Aquila could evolve into a major new resource within a contiguous, strategically located mineralised corridor. In addition to the strong drill results, True North Copper Limited is moving ahead with an expanded exploration strategy. The company plans to extend induced polarisation surveys over approximately 3 kilometres north and south of the current discovery and deploy high-resolution drone magnetics to enhance structural understanding in the broader Mt Gordon Fault Zone. Follow-up drilling designs and permitting are being prepared, and further assay results are expected to clarify the full potential of the deposit. The news brings a bullish sentiment as technical indicators support a sizable, open mineral system with both high-grade zones and regional connectivity. The use of standard, industry-recognised drilling and assay protocols alongside advanced geophysical techniques underpins the discovery’s credibility. However, some caution is warranted; operational challenges such as a mechanical failure in MOX231, which led to premature hole termination, highlight the inherent risks in early-stage exploration. Overall, the discovery signals substantial upside potential, while also reminding investors that further work is needed to fully define and quantify the resource.
