Southern Silver drills 35.0 metres averaging 188 g/t Ag, 4.9% Pb and 4.6% Zn at Cerro Las Minitas Project, Durango, Mexico

Southern Silver Exploration Corp. [TSXV: SSV] reported assays from the first five holes of the definition drill program on the Puro Corazon target at the Cerro Las Minitas Project, Durango, Mexico which provide better resolution to the distribution of the strongly silver enriched polymetallic mineralization.

Highlight assays include: a 35.0-metre interval averaging 188 g/t Ag, 0.3% g/t Cu, 4.9% Pb and 4.6% Zn (399 g/t AgEq), including a 9.4-metre interval averaging 344 g/t Ag, 0.2% Cu, 9.1% Pb and 6.7% Zn (665 g/t AgEq) from drillhole 26CLM-225; a 5.2-metre interval averaging 277 g/t Ag, 0.1% Cu, 9.9% Pb and 6.3% Zn (598 g/t AgEq), including a 3.6-metre interval averaging 384 g/t Ag, 0.1% Cu, 13.4% Pb and 8.3% Zn (812 g/t AgEq) from drillhole 26CLM-226; and a 5.3-metre interval averaging 493 g/t Ag, 0.3% Cu, 10.2% Pb and 7.2% Zn (850 g/t AgEq) from drillhole 26CLM-227.

These initial results are from the ongoing 14,000-metre core hole drill program that was started in June and is designed to upgrade resource classification in the Puro Corazon target. The current drill program will test an area that is roughly a 200-metre strike-length by 300 metres down dip within the Puro Corazon claim.

The above reported drill holes successfully targeted the upper part of the zone with nominal 40-metre step-outs from previously reported intercepts that include 10.5 metres averaging 1,115g/t AgEq from 25CLM-203 and 10.4 metres averaging 743g/t AgEq from 25CLM-205 as well as other mineralized intercepts.

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 and the main skarn target.

Rob Macdonald, Vice President of Exploration, stated, “This is a very solid start to the definition drill program on the Cerro Las Minitas Project. These initial step out holes not only help confirm the previously reported thicknesses and grades of mineralization in this target area, but provide better definition as to the projection of several of the mineralized zones. Drilling continues on the project and the Company anticipates good news flow over the coming weeks and months.”

Drilling continues with eight of 30 planned holes having been completed to date with one hole in progress. Logging and sampling continue and assays from three holes are pending.

Work continues to incorporate results from the earlier 2025-26 Puro Corazon drilling into the larger Cerro Las Minitas project which is expected to enhance the project economics and the scalability of the mine plan. Work 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.

Southern Silver’s focus 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.

The company has assembled a team of 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. Southern Silver’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.
