• Drill hole MR25-230 returns extensive mineralised zone intercepted above the delineated Mineral Resource
• Significant gold zone of 5.3m at 3.65g/t Au from 198.12m
• Drilling further supports Maverick Springs' emergence as a world-class, district-scale precious metals deposit

Sun Silver Limited is pleased to report further assays from its ongoing 2025 exploration program at the Maverick Springs Silver-Gold Project in Nevada, USA. Drill hole MR25-230 was completed with a RC pre-collar and a diamond (HQ) tail to a depth of 335.28m as part of the infill drilling in the south-central part of the Project. Testing the mineralisation model along a section line of Pre-2002 era historic drilling, the drill hole successfully intercepted mineralisation shallower than expected. The drill hole returned a 140.21m interval at 71g/t AgEq (25.8g/t Ag, 0.53g/t Au) from 160.02m, including a 39.08m zone at 151g/t AgEq (57.3g/t Ag, 1.10g/t Au) from 198.12m. Significantly, this mineralisation was intercepted 26m above the defined Mineral Resource. The drill hole also produced cumulative Antimony zones over 79m, with the highest-grade intervals returning up to 3,137ppm Sb. The silver mineralisation was complemented with Project significant high-grade gold intercepts returning grades over 4g/t and up to 19 gram-meters. The addition of continuous antimony anomalism within the same zone highlights the importance of this south-central area to the Project which remains open and only sparsely drilled to the South.

The drilling results further support Maverick Springs' emergence as a world-class, district-scale precious metals deposit with meaningful silver, gold, and antimony endowment. The deposit remains open along strike and at depth, with multiple mineralised intercepts located outside of the current Resource constrained model.
