• Drill-hole MR25-212 confirms the extension of mineralisation to the north at Maverick Springs, with assays returning an extensive mineralised zone of 54.1m at 137g/t AgEq
• Intercepts include 6.25m at 506g/t AgEq, demonstrating the high-grade nature of the mineralisation
• Results continue to highlight the quality and scale of the Maverick Springs deposit, reinforcing its status as one of the largest undeveloped primary silver projects in the US

Sun Silver Limited (ASX Code: 'SS1') ('Sun Silver' or 'the Company') is pleased to report further assays from its ongoing 2025 exploration program at the Maverick Springs Silver-Gold Project in Nevada, USA ('Maverick Springs Project' or 'the Project'). Drill hole MR25-212 has returned multiple mineralised zones on the north-western edge of the Maverick Springs Mineral Resource, confirming the extension of mineralisation to the north. The drill-hole intercepted an extensive mineralised zone of 54.1m at 137g/t AgEq (116.7g/t Ag, 0.23g/t Au) from 230.1m, including a high-grade interval of 6.25m at 506g/t AgEq (484.8g/t Ag, 0.25g/t Au) from 270.5m. These results demonstrate the broad, high-grade nature of the mineralisation on the north-western margin of the Maverick Springs Resource and highlight the excellent potential for future resource growth in this area. The Maverick Springs Project hosts a JORC Inferred Mineral Resource of 218Mt grading 42.2g/t Ag and 0.31g/t Au for 296.5Moz of contained silver and 2.2Moz of contained gold (480Moz of contained silver equivalent), with the deposit remaining open along strike and at depth. The latest results from drill-hole MR25-212 continue to reinforce the quality and scale of the Maverick Springs deposit, further strengthening its status as one of the largest undeveloped primary silver projects in the US.
