True North Copper has updated the Mineral Resource Estimate for its Wynberg project near Cloncurry, reporting a total of 1.02 million tonnes at 1.86 g/t gold, 0.25% copper, and 0.51 ppm silver. This new estimate, which contains 61,000 ounces of gold and 3,000 tonnes of copper, moves the project beyond its previous status as a gold-only deposit by incorporating copper and silver inventory for the first time.

The 2026 resource figure marks a material change from the 2022 estimate, which reported 0.64 million tonnes at 2.7 g/t gold for 56,100 contained ounces. The updated resource reflects a larger total tonnage, though the average gold grade has decreased as a result of using a lower cut-off grade of 0.4 g/t gold, compared to the previous 0.75 g/t threshold. The current estimate is also constrained within a conceptual open pit shell.

Following this update, the total resource base for the broader Cloncurry Copper Project has reached 17.75 million tonnes at 0.73% copper and 0.26 g/t gold, containing 128,000 tonnes of copper and 152,000 ounces of gold.

The company is currently progressing technical and metallurgical assessments to evaluate the integration of the Wynberg mineralisation into the wider Cloncurry operations.
