[{"type":"text","content":"Southern Silver Intersects 10.5 metres averaging 1,115g/t AgEq at Cerro Las Minitas Project in Durango, MéxicoVancouver, British Columbia--(Newsfile Corp. - December 1, 2025) - Southern Silver Exploration Corp. (TSXV: SSV) (the \"Company\" or \"Southern Silver\") reports today that rush assays from initial drilling on the recently acquired Puro Corazon claim have returned near surface Bonanza-grade silver mineralization from thick, semi-massive to massive-sulphide replacements in a hanging-wall lens outside of the main skarn target. The highlight assays were returned from hole 25CLM-203 and include:10.5 metre interval (estimated true thickness) averaging 560g/t Ag, 0.1g/t Au, 0.1% Cu, 11.2% Pb and 12.3% Zn (1,115g/t AgEq), including a 3.4 metre interval (estimated true thickness) averaging 1,067g/t Ag, 0.2g/t Au, 0.2% Cu, 20.0% Pb and 19.1% Zn (1,982g/t AgEq)(1) located within 200 metres of surface; and two narrower, high-grade intercepts occurring several metres down hole from the highlight intercept (above), which composite to a 2.6 metre interval (estimated true thickness) averaging 143g/t Ag, 4.8% Pb and 1.5%% Zn (280g/t AgEq) (1) located a further 6 metres down hole.(1) see AgEq calculation criteria in notes to Table 1. The replacement interval contains semi-massive to massive sulphides with up to 40% sphalerite (zinc), 30% galena (lead) and lesser pyrite with silver mineralization most strongly correlated to the galena content and represents a carbonate replacement hosted in limestone sitting outside of the main skarn zone and the historic Puro Corazon workings. Several additional mineralized zones were intersected deeper in drill hole 25CLM-203 including intervals of variably mineralized skarn. The intervals have been sampled and submitted for analyses; assays remain pending and will be released upon receipt. In addition, step-out holes from 25CLM-203 have intersected similar replacement-style massive to semi-massive sulphide intercepts both laterally and at depth. These intervals have been logged and sampled, with assays pending. Vice President of Exploration, Rob Macdonald stated \"We're off to a strong start at Puro Corazon. These initial bonanza-grade silver intercepts confirm the near surface, high-grade nature of the mineralization and the overall prospectivity of the recently acquired Puro Corazon claim. With ...
