• Drilling continued at Jims Gold Mine, with several high-grade intercepts returned
• Final assays received for drilling at Groundrush Gold Deposit, including multiple high-grade intercepts
• Updated Mineral Resource estimate completed, now totaling 31 Mt at 2.8 g/t gold for 2.8 Moz

Tanami Gold NL reported on its activities for the December 2025 quarter, including continued drilling across the Central Tanami Project. At the Jims Gold Mine, the final 1,198 metres of a Reverse Circulation Pre-Collar/Diamond Core Tail (RCD) drilling program were completed, with assay results received for all holes. The drilling confirmed the continuity of mineralization over an approximate 900-metre strike length and to a vertical extent of 500 metres, with mineralization remaining open to the north and at depth. Final assay results were also received for a 27-hole Reverse Circulation (RC) and RCD drilling program at the southern end of the Groundrush Gold Deposit, returning multiple high-grade intercepts. This program was designed to improve confidence in the Mineral Resource ahead of future updates and mining studies.The quarter also marked the completion of the Project-wide Mineral Resource update, with the estimate now totaling 31 Mt at 2.8 g/t gold for 2.8 Moz as of 30 September 2025, representing an 18% increase in tonnes, a 9% increase in contained ounces, and an 8% decrease in grade compared to the previously reported estimate.
