• Total Mineral Resource of 31 Mt at 2.8 g/t gold for 2.8 Moz
• 18% increase in tonnes, 9% increase in contained ounces, 8% decrease in grade
• Drilling, higher gold price, and improved recoveries drive the increase

Tanami Gold NL has updated the Mineral Resource estimates for the Central Tanami Project in the Northern Territory, with a total Mineral Resource of 31 Mt at 2.8 g/t gold for 2.8 Moz as at 30 September 2025. This represents an 18% increase in tonnes, 9% increase in contained ounces, and an 8% decrease in grade compared to the previously reported Mineral Resource estimate dated 30 June 2023. The increase is primarily due to drilling completed since 30 June 2023, higher gold price assumptions, and improved metallurgical recoveries for fresh material classified as refractory. The updated estimates were compiled by mining consultant MoJoe Mining Pty Ltd using revised geological models that more accurately represent the mineralised systems. Reported Mineral Resources have been rigorously constrained by Pit and Stope Optimisations, with deposit-specific cut-off grades based on a A$3,500/oz gold price, haulage to the existing Central Tanami mill site, benchmark operating costs, and recoveries derived from a free-milling CIL circuit or concentrate production for refractory mineralisation. The updated estimates do not include all results from drilling completed during the 2025 field season at the key targets Jims Gold Mine and Groundrush Gold Deposit, both of which remain open down plunge.

The updated Mineral Resource estimate includes 11 Mt at 3.3 g/t gold for 1.2 Moz from the key Groundrush Gold Deposit.
