Southern Silver Exploration Corp. (TSXV: SSV) has released assay results from the first five holes of its definition drill program on the Puro Corazon target at the Cerro Las Minitas silver-lead-zinc project in Durango, Mexico. Highlight results include a 35.0-metre interval averaging 188g/t Ag, 4.9% Pb, and 4.6% Zn (399g/t AgEq) from drillhole 26CLM-225. The results are part of an ongoing 14,000-metre core hole program launched in June 2026, designed to upgrade resource classification at the target. Investors may be watching closely as the company reports eight of 30 planned holes completed, with assays from three additional holes pending.

Key Points

  • Southern Silver Exploration Corp. (TSXV: SSV)
  • Definition drilling at Puro Corazon returns highlight interval of 35.0 metres averaging 399g/t AgEq from 26CLM-225
  • Program targets a roughly 200-metre strike-length by 300-metre down-dip area; 8 of 30 holes completed to date
  • Investors should watch for incoming assays from three pending holes as drilling continues

Puro Corazon Definition Drilling Returns High-Grade Silver-Lead-Zinc Intercepts

The release states that drillhole 26CLM-225 returned a 35.0-metre interval averaging 188g/t Ag, 0.3% Cu, 4.9% Pb, and 4.6% Zn (399g/t AgEq), including a higher-grade 9.4-metre sub-interval averaging 344g/t Ag, 9.1% Pb, and 6.7% Zn (665g/t AgEq). Drillhole 26CLM-226 delivered a 5.2-metre interval at 277g/t Ag, 9.9% Pb, and 6.3% Zn (598g/t AgEq), with a 3.6-metre sub-interval reaching 812g/t AgEq. Drillhole 26CLM-227 intersected 5.3 metres averaging 493g/t Ag, 10.2% Pb, and 7.2% Zn (850g/t AgEq), representing some of the strongest grades reported in this release.

Step-Out Holes Confirm Continuity from Prior Cerro Las Minitas Intercepts

The disclosure indicates the reported holes are nominal 40-metre step-outs from previously announced intercepts, including 10.5 metres averaging 1,115g/t AgEq from hole 25CLM-203 and 10.4 metres averaging 743g/t AgEq from 25CLM-205. Both skarn and replacement styles of mineralisation were identified, with several intercepts correlating to the El Sol structural zone and the main skarn target. Vice President of Exploration Rob Macdonald stated the 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."

Cerro Las Minitas Project Advancement and Baseline Studies Under Way

Beyond drilling, the company states that work continues to incorporate 2025–26 Puro Corazon results into the broader Cerro Las Minitas project model, with the aim of enhancing project economics and mine plan scalability. Baseline data collection, hydrology, geotechnical, archaeological, and land surveys are also advancing. The project is described as a large-scale underground mining operation situated in southeast Durango, Mexico. The company's current economic assessment references a Preliminary Economic Assessment dated June 10, 2024, and additional upside opportunities identified subsequent to that study are being evaluated.
