Southern Silver Exploration Corp. (TSX-V: SSV) reports additional assays from drilling which continues to outline extensions of mineralization on the recently acquired Puro Corazon claim and identified further thick intervals of high-grade and strongly silver-enriched polymetallic mineralization.

Highlight assays include:

• a 5.8 metre interval averaging 173g/t Ag, 1.5% Cu, 1.8% Pb and 17.3% Zn (781g/t AgEq)⁽¹⁾ from drillhole 25CLM-210; and
• a 10.8 metre interval averaging 121g/t Ag, 0.3% Cu, 5.1% Pb and 3.9% Zn (348g/t AgEq), including
• a 3.1 metre interval averaging 225g/t Ag, 0.6% Cu, 9.4% Pb and 7.1% Zn (642g/t AgEq)⁽¹⁾ from drillhole 25CLM-210
• a 3.0 metre interval averaging 715g/t Ag, 0.1g/t Au, 7.5% Pb and 1.0% Zn (890g/t AgEq)⁽¹⁾ from drillhole 25CLM-212

(1) see AgEq calculation criteria in notes to Table 1. Intervals are reported as estimated true thickness unless otherwise indicated

The drill results, specifically from holes 25CLM-210 and 25CLM-215 continue to extend mineralization to depth, below earlier reported results from the Puro Corazon target as well as testing mineralization toward the southern edge of the claim with drill holes 25CLM-211 to 25CLM-214. Previously released intercepts from this round of drilling include:

• 10.5 metres grading 1,115g/t AgEq (see News Release dated December 1, 2025) from 25CLM-203
• 10.4 metres grading 743g/t AgEq (see News Release dated January 6, 2026) from 25CLM-205; and
• 15.3 metres grading 581g/t AgEq (see News Release dated January 27, 2026) from 25CLM-206

Drilling continues to demonstrate the continuity of the high-grade replacement lens first identified in drill holes 25CLM-203 and 25CLM-205 and has now extended mineralization to a depth of over 360 metres below surface in the main skarn target.

Twenty-one core holes out of twenty-two planned holes have been completed to date and a final hole is in progress.  Analyses from fourteen drill holes have now been reported and further assays, including those from underground sampling of the historic Puro Corazon workings, are anticipated over the coming weeks.

Next Steps

The Company is planning to incorporate the results of the Puro Corazon drilling program into the much larger Cerro Las Minitas project which is expected to significantly enhance the project economics. Final assays are anticipated to be received by the end of the first quarter of 2026, after which the Company intends to:

• update the Mineral Resource Estimate of the Cerro Las Minitas project; followed by
• an update of the Preliminary economic Assessment (“PEA”) of the project in accordance with the provisions of National Instrument 43-101 and
• continue to advance baseline data collection and permit readiness review

The Company reports that work on the Cerro Las Minitas project continues advancing numerous upside opportunities identified subsequent to the July 2024 PEA, while also derisking and advancing the project with the commencement of baseline data collection, hydrology, geotechnical, archaeological and land surveys and studies.

As currently modelled, the Cerro Las Minitas project features a large-scale underground mining operation with robust project economics and high gross revenues in a well located and mining friendly jurisdiction in southeast Durango, Mexico. For more information on the details of the current economic assessment of the Cerro Las Minitas project please refer to Southern Silver’s news release dated June 10, 2024.

About Southern Silver Exploration Corp.

Southern Silver Exploration Corp. is an exploration and development company with a focus on the discovery of world-class mineral deposits either directly or through joint-venture relationships in mineral properties in major jurisdictions. Our specific emphasis is the 100% owned Cerro Las Minitas silver-lead-zinc project located in the heart of Mexico’s Faja de Plata, which hosts multiple world-class mineral deposits such as Penasquito, Los Gatos, San Martin, Naica and Pitarrilla. We have assembled a team of highly experienced technical, operational and transactional professionals to support our exploration efforts in developing the Cerro Las Minitas project into a premier, high-grade, silver-lead-zinc mine. Located in the same State as the Cerro Las Minitas property is the newly acquired Nazas, gold-silver property. Our property portfolio also includes the Oro porphyry copper-gold project and the Hermanas gold-silver vein project where permitting applications for the conduct of a drill program is underway, both located in southern New Mexico, USA.
