Southern Silver drills 4.6 metres averaging 201 g/t Ag, 4.5% Pb and 9.8% Zn (557 g/t AgEq) at Puro Corazon claim, Mexico

Southern Silver Exploration Corp. [TSXV: SSV; OTCQX: SSVFF] reported the final assays from drilling on the Puro Corazon claim, Durango, Mexico that continues to extend mineralization to depth and identify additional thick intervals of high-grade and strongly silver-enriched polymetallic mineralization.

Highlight assays include a 4.6-metre interval averaging 201 g/t Ag, 0.1% g/t Cu, 4.5% Pb and 9.8% Zn (557 g/t AgEq), including a 1.5-metre interval averaging 401 g/t Ag, 0.2% Cu, 8.9% Pb and 22.3% Zn (1181 g/t AgEq) from drillhole 26CLM-221; and a 9.3-metre interval averaging 62 g/t Ag, 0.1% Cu, 0.2% Pb and 6.0% Zn (234 g/t AgEq), including a 2.2-metre interval averaging 135 g/t Ag, 0.2% Cu, 0.4% Pb and 13.5% Zn (522 g/t AgEq) from drillhole 26CLM-223.

Both skarn and replacement styles of mineralization are identified in these holes with several intercepts, located well outboard of the Skarn zone, correlating with previous identified mineralization in the El Sol structural zone.

All 23 of the planned holes in the current drill program are now complete and drill crews have been demobilized from the property. Analyses from all drill holes have been reported. Sampling and mapping within the 13 levels of the historic Puro Corazon mine workings continues with up to 212 channel samples totaling over 1300 individual samples having been collected to date. Assay results from this sampling are being compiled and will be reported in the coming weeks.

Vice President of Exploration, Rob Macdonald, stated,  “The 2025-26 drill program successfully outlined and upgraded mineralization on the Puro Corazon claim; extending mineralization within the skarn-altered halo around the main intrusion for upwards of 400 metres laterally and to depths of up to 500 metres below surface, where it transitions into previously identified mineralization in the larger CLM claim block.

“More significantly, drilling also intersected multiple bonanza-grade, replacement-styled intercepts on the outer edge of the skarn-altered halo, potentially forming a shallow high-grade lens outboard of the main skarn zone and starting within 200 metres of surface. This mineralization is adjacent to existing historical mine workings and could be accessed early in a mine plan scenario.”

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 and the scalability of the mine plan.

Final assay results have been received and the next steps for the company include updating 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 NI 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.

Southern Silver Exploration’s 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. Located in the same State as the Cerro Las Minitas property is the newly acquired Nazas, gold-silver property. The company’s 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.
