Encouraging Results from Jims

• Final assay results received from 2025 drilling program at Jims Gold Mine
• Several high-grade intercepts, including 7.30m @ 6.74 g/t gold and 13.00m @ 6.61 g/t gold
• New drilling program commenced to further evaluate the deposit

Tanami Gold NL has received the final assay results from the 2025 Reverse Circulation Pre-collar/Diamond Core Tail (RCD) drilling program completed at the historic Jims Gold Mine, located within the Central Tanami Project Joint Venture (CTPJV). The program was designed to assess the down-dip and northerly extensions of the Jims Main zone, building on the successful 2024 drilling campaign. The final assays have returned a series of encouraging intercepts, including 7.30 metres @ 6.74 g/t gold, 8.00 metres @ 5.60 g/t gold, 11.92 metres @ 3.57 g/t gold, 20.23 metres @ 1.68 g/t gold, 2.00 metres @ 27.48 g/t gold, 13.00 metres @ 6.61 g/t gold, and 7.65 metres @ 4.99 g/t gold. These results further elevate the strategic importance of the Jims area within the broader CTPJV portfolio. Based on the strength of these findings, a second phase of RCD drilling totalling 9 holes for 5,200 metres has now commenced, with assay results anticipated in early 2026.

A new Reverse Circulation Pre-collar/Diamond Core Tail drilling campaign has now commenced at Jims Gold Mine. This program is expected to be completed prior to the onset of the northern Australian wet season, with assay results anticipated in early 2026.
