• Thick mineralised intercepts returned with grades exceeding the existing mineral resource
• Extensive gold mineralisation intercept within one of the holes
• High grade antimony zones intercepted in one of the holes
• Drilling continues to replicate predicted mineralised zones and test open extensions

Sun Silver Limited has reported further assays from its 2025 exploration program at the Maverick Springs Silver-Gold Project in Nevada, USA. Drilling has continued to deliver thick, high-grade silver-gold mineralisation at grades above the existing mineral resource, reinforcing both the scale and quality of the Maverick Springs system. Highlights include: 102.1m at 86.2g/t AgEq (49.1g/t Ag and 0.44g/t Au) from 192m, including 50.6m at 149g/t AgEq (91.7g/t Ag and 0.67g/t Au) from 192m; and an extensive gold mineralisation intercept of 10.7m at 1.59g/t Au from 192m. The drilling also intercepted high grade antimony zones, including 9.1m at 1% Sb with individual assays up to 9.3% from 195.9m. The drilling continues to replicate predicted mineralised zones and test open extensions of the model, reinforcing the reliability of the current geological framework and improving definition of mineralisation distribution across the resource. Silver led global commodity performance in 2025 and is currently trading above USD $100/oz. Silver was also recently added to the 2025 U.S. Department of Interior Critical Minerals List, enhancing both Australian federal and U.S. government interest in Maverick Springs.

The Company continues to deliver thick, high-grade silver-gold mineralisation at grades above the existing mineral resource, reinforcing both the scale and quality of the Maverick Springs system. The presence of high-grade antimony further enhances the project's strategic value as silver and critical minerals markets continue to strengthen.
