 High Grade Mineralisation Confirmed at Surface
Key Points
  • Rock chip sampling confirms silver and gold mineralisation at surface
  • Exceptional grades of up to 86.9g/t AgEq and 0.12% Sb
  • Shallow and surface mineralisation to be incorporated into future resource modelling
Full Summary

Sun Silver Limited (ASX Code: 'SS1') is pleased to announce the results from recent reconnaissance rock chip sampling at its Maverick Springs Silver-Gold Project in Nevada, USA, which have confirmed significant silver and gold mineralisation from surface outcrops. The sampling program targeted outcropping alteration zones mapped at surface, with a focus on follow-up sampling of rock chip anomalies taken in June. The exceptional grades returned from sample J414108, combined with elevated pathfinder elements, confirm the presence of high-grade mineralisation in accessible, from surface positions, providing further targets for drilling as part of proving up the from surface mineralisation. Sun Silver aims to incorporate shallow and surface mineralisation into future mineral resource modelling. The Maverick Springs Project, which is proximal to the prolific Carlin Trend, 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).

Outlook

Sun Silver is encouraged by the high-grade, near-surface results at Maverick Springs, as the presence of mineralisation at surface provides important commercial flexibility in future studies, including the potential to generate early-stage revenue from surface material. With such a large existing resource now trending toward a from-surface model, Maverick Springs is positioned as one of the leading emerging silver projects in the United States, and well-placed to attract the attention of the US government as it seeks to secure domestic mineral supplies.
