True North Copper finds more scale at Mt Oxide as Cloncurry advances

Mt Oxide drilling pushes Aquila deeper

True North Copper Limited (ASX:TNC) has used its September quarter to turn a promising exploration story into a larger, more defined system, extending high-grade copper mineralisation at Aquila to approximately 300 metres below surface. One result returned 130 metres at 0.67% copper from 180 metres, including 6 metres at 5.70% copper, while another delivered 35 metres at 0.82% copper, including 9.2 metres at 2.21%.

Maiden drilling at Chidna, about 400 metres north of Aquila, added scale rather than simply another isolated intercept. The company interpreted a mineralised zone approximately 300 metres wide, extending the tested Aquila-Chidna trend to roughly 2.3 kilometres. The broader structural corridor is now interpreted to extend beyond 4 kilometres, although True North explicitly says that this is an exploration corridor, not continuous mineralisation confirmed by drilling. The earlier Chidna maiden drilling had already taken the known strike to 2.3km.

Cloncurry moves closer to a development test

At the Cloncurry Copper Project, the company is trying to convert resource growth and metallurgy into a development case. Contained copper-equivalent resources reached 204kt, up 62% from December 2025, following the consolidation of the Mongoose-Taipan resource and other project updates. Wallace North also produced substantial copper-gold intersections, including 24.5 metres at 2.17% copper and 2.01 grams per tonne gold, with the higher-grade shoot remaining open along strike and at depth.

The technical work is becoming more concrete. Wallace North flotation tests averaged 88.9% copper recovery at a 19.9% concentrate grade across three composites, with recoveries ranging from 83.4% to 95.8%. The company says the Cloncurry pre-feasibility study and potential Ore Reserve remain targeted for late 2026. That milestone matters because the project is still a mineral-resource story rather than an economic reserve, and the study must bring together mine planning, processing, approvals and commercial options. The Cloncurry recovery update had previously outlined the same 88.9% flotation recovery and late-2026 study target.

Wynberg adds a smaller development option

True North also reported a Wynberg gold-copper scoping study based on a 1.02 million tonne resource grading 1.86 grams per tonne gold and 0.25% copper. The study outlines a potential shallow open-pit operation targeting 53koz of gold equivalent, with estimated pre-tax cash flow of $53 million to $87 million and funding requirements of approximately $23 million to $38 million, depending on the processing pathway and other assumptions.

Those figures are scoping-study estimates, not a production commitment. The proposed two-year operation would rely on contract mining and existing regional processing infrastructure, with possible standalone, toll-treatment or future Cloncurry integration pathways. The study therefore offers optionality, but it also leaves financing, processing arrangements, approvals and further technical work unresolved.

Capital raise buys time, not independence from funding

True North raised $18.75 million through an $18 million placement and a $750,000 share purchase plan. At quarter-end it held $12.8 million in cash, after spending $5.5 million on exploration and $1.1 million on operating activities. The company says the funds will support the final A$7.5 million deferred consideration payment for Mt Oxide, due in December 2026, as well as exploration and development studies.

The cash-flow disclosure supplies the less comfortable counterpoint to the exploration progress: on current outgoings, the Appendix 5B calculates only 1.93 quarters of funding. True North says it has sufficient capital to complete its current exploration program and that the second placement tranche, settled after quarter-end, added a further gross $5.754 million. Its stated ability to continue operations nevertheless depends on raising additional capital when required, leaving the next study results and the December Mt Oxide payment to compete for investor attention.
