Southern Silver Reports Updated Mineral Resource For Cerro Las Minitas Project

Southern Silver Exploration (TSX.V:SSV) (“Southern”) reports that Kirkham Geosystems (“KGL”) has completed an update of its independent Mineral Resource Estimate on the Cerro Las Minitas (“CLM”) project in Durango State, Mexico, operated on a joint venture basis by SSV(40%) as operator and Electrum Global Holdings LP(60%).

This Mineral Resource Estimate showcases the continuity of the mineralization and continued expansion of the Cerro Las Minitas project and updates the previously reported March 2016 estimate. The new Resource Estimate incorporates additional data from drilling conducted in 2016 and 2017 that has successfully delineated a major new deposit on the project and significantly increased the resource base in both the Indicated and Inferred Resource categories as well as improving the overall grade of the resource, most significantly in the Indicated category.

Resource Model Highlights

In comparison to the 2016 Mineral Resource estimate, the 2017 update, at a 175g/t AgEq cut-off, features:

• A318% increase in Indicated Mineral resources to: 10.1Mt averaging 102g/t Ag, 0.1g/t Au, 0.15% Cu, 1.4% Pb and 3.6% Zn (356g/t AgEq, 7.6% ZnEq);
• A18% increase in Inferred Mineral resources to: 8.7Mt averaging 74g/t Ag, 0.04g/t Au, 0.15% Cu, 0.7% Pb and 4.5% Zn (332g/t AgEq, 7.0% ZnEq);

• the utilization of a higher cut-off (175g/t AgEq) to reflect potential mining costs and metal recoveries;
• an increase in the average grade, as denoted in AgEq, of the Indicated Resources; and
• the newly delineated Skarn Front zone which now forms the single largest mineral deposit in the Cerro Las Minitas Project area.
