• Thick mineralised intercepts returned from multiple holes at grades consistent with and exceeding the mineral resource grade
• Extensive gold mineralisation intercept within MR25-235
• Drillhole results continue to successfully intercept mineralisation in line with the existing mineralisation model
• Silver recently added to the 2025 US Department of Interior Critical Minerals List

Sun Silver Limited is pleased to report further assays from its 2025 exploration program at the Maverick Springs Silver-Gold Project in Nevada, USA. The drilling continues to deliver thick, high-grade silver-gold intercepts, confirming the scale and continuity of the system. Highlights include: MR25-227 returning 123.94m at 81.8g/t AgEq (51g/t Ag and 0.36g/t Au) from 216.80m, including 33.77m at 224.5g/t AgEq (168 g/t Ag and 0.66 g/t Au); MR25-229 returning 45.78m at 76.7g/t AgEq (46.8g/t Ag and 0.35g/t Au) including 15.58m at 114.6 AgEq (77.2g/t Ag and 0.44g/t Au); and an extensive gold mineralisation intercept within MR25-235 of 29.69m at 201.9g/t AgEq (85.1g/t Ag and 1.37g/t Au). The drillhole results continue to successfully intercept mineralisation in line with the existing mineralisation model, providing further confidence in the model while building on mineralisation distribution knowledge of the resource. The inclusion of silver on the 2025 US Department of Interior Critical Minerals List enhances both Australian federal and U.S. government interest in Maverick Springs, which is well positioned to benefit from strong silver market fundamentals and strategic supply-chain tailwinds.
