True North Copper (ASX:TNC) has confirmed a new ‘high-grade’ copper and gold structure from diamond drilling at its Cloncurry Copper Project in northwest Queensland.
Drilling at the Wallace North prospect delivered a significant intercept of 24.5m @ 2.17% copper (Cu) and 2.01 grams per tonne gold (Au) for 4.2% copper equivalent from 117m, including 3.3m @ 10.11% Cu and 7.93g/t Au for 18.1% Cu equivalent.
Additional drilling adjacent to the main lode extension intersected 11m @ 2.45% Cu and 0.43g/t Au for 2.9% Cu equivalent.
Managing Director Andrew Mooney says the results represent another step in growing and adding value to the project, improving the True North’s understanding of the mineralised system.
“Together with the strong 2025 drilling results, this gives us greater confidence to grow the resource through targeted follow-up drilling and highlights the longer-term underground potential of the system,” Mooney says.
“The broader 2026 drilling program has also strengthened the emerging Wallace-Wynberg copper-gold structure, with additional shallow gold-copper mineralisation identified close to existing infrastructure, on mining leases, providing further opportunities to expand resources and enhance the overall value of the Cloncurry Copper Project.”
The company completed nine reverse circulation holes for 1,806m and one diamond drill hole for 300.5m during the program to support future reserve conversion and Prefeasibility Study (PFS) workstreams.
Remaining assay results and metallurgical test work programs are expected through to September, while outcome integration into future resource growth, reserve, and PFS workstreams are targeted for Q4 2026.
The Cloncurry Project contains a combined indicated and inferred resource of 125,720 tonnes of copper and 91,300 ounces of gold across multiple deposits, including 2 million tonnes @ 1.28% Cu and 0.77g/t Au at Wallace North.
True North Copper is a mineral explorer focused on copper, silver, gold, and cobalt in Queensland’s Mt Isa region.
