True North Copper Limited has intersected high-grade copper mineralisation extending to approximately 300 metres below surface at the Aquila discovery within the Mt Oxide Project in Queensland, marking a 100-metre depth extension from previous drilling.

Assay results from three recent drillholes at the northern high-grade shoot returned broad composite intervals with distinct higher-grade zones. Hole MOXRC26_010 intersected 130 metres at 0.67% copper, 0.07% cobalt and 1.50g/t silver from 180 metres. This included a 44-metre section at 1.54% copper from 266 metres, stepping down to a 16-metre interval at 3.67% copper from 286 metres and a 6-metre core grading 5.70% copper from 295 metres.

Additional drilling from the program further confirmed the system's geometry. Hole MOXRC26_009 returned 74 metres at 0.73% copper from 159 metres, including an 11-metre interval at 1.64% copper from 161 metres. Hole MOXRC26_008 intersected 31 metres at 0.90% copper from 68 metres, including a 7-metre section at 1.39% copper from 74 metres.

The results establish a true width of approximately 40 to 60 metres for the mineralised package and demonstrate that high-grade zones persist beneath the interpreted induced polarisation geophysical anomaly, remaining open at depth.

“These latest results continue to strengthen confidence in the Aquila discovery and reinforce our belief that we're building a significant new copper system at Mt Oxide. The 130m intersection, including 6m @ 5.70% Cu at depth, is particularly encouraging and extends the northern high-grade shoot to approximately 300 metres below surface, where it remains open.”

The Mt Oxide Project hosts both the Vero Resource and the Aquila discovery, forming a core asset within the company's portfolio. True North Copper operates under a three-platform growth strategy encompassing resource expansion at Mt Oxide, developing near-term cash flow at the Cloncurry Copper Project, and pursuing regional discovery targets.

The ongoing 2026 exploration program will continue drilling to expand the Aquila mineral system along strike and at depth while defining the geometry of higher-grade zones. The company also plans to release further assay results from Mt Oxide over the coming months.
