• High-grade copper, zinc and gold intercepts continue to highlight potential for mine life extensions of existing Gossan Hill Deposits
• Results indicate that Ozion and Hougoumont Extended are potentially a single large mineralised system at depth, which could enable future mining cost efficiencies
• Resource Extension drilling intercepted high-grade copper, zinc and gold in both copper and zinc dominant zones

29Metals Limited announced results from Near Mine Exploration, Resource Extension, and Resource Conversion drilling at its Golden Grove operations. The drilling results include high-grade copper, zinc and gold intercepts that continue to highlight the potential for mine life extensions of existing Gossan Hill Deposits. The results also indicate that the Ozion and Hougoumont Extended deposits are potentially a single large mineralised system at depth, which could enable future mining cost efficiencies via shared infrastructure in this area. Resource Extension drilling in the copper dominant zone at Oizon and Hougoumont Extended intercepted significant intervals including 9.7m @ 1.5% Cu, 2.6% Zn, 1.0g/t Au, 18g/t Ag and 12.5m @ 1.5% Cu, 0.7g/t Au, 22g/t Ag. Resource Extension drilling in the zinc dominant zone intercepted intervals such as 16.9m @ 1.6% Cu, 6.2% Zn, 0.8g/t Au, 21g/t Ag and 21.6m @ 0.3% Cu, 17.6% Zn, 1.6g/t Au, 49g/t Ag, 1.0% Pb. Resource Extension drilling at Europa also intercepted high-grade copper including 17m @ 1.6% Cu, 0.2g/t Au, 13g/t Ag. The results reported are not included in 29Metals' previous Mineral Resources & Ore Reserves estimates.

The 2025 drill program to test priority targets at Golden Grove remains ongoing with approximately 9,000m of drilling remaining, which will be split across the target areas reported in this release along with Tryall and Cervantes. The next update to 29Metals' Mineral Resources and Ore Reserves estimates is planned to be published during the March Quarter 2026.
