Southern Silver posts 2.8 metres of 665 g/t AgEq and 4.0 metres of 367 g/t AgEq from underground channel sampling at the Puro Corazon Mine, Mexico

• Southern Silver intercepted high-grade silver mineralization at Puro Corazon with a peak result of 665 g/t AgEq over 2.8 metres, indicating robust near-surface underground potential.
• The second intercept of 367 g/t AgEq over 4.0 metres demonstrates consistent mineralization widths, suggesting the vein system has reasonable continuity and tonnage potential.
• Underground channel sampling from an operating mine provides direct geological evidence of grade and thickness, reducing exploration risk compared to drilling alone.
• Silver-equivalent grades in the hundreds of g/t range are considered high-grade for underground mining projects and support economic viability of near-surface extraction.
