The Critical Metals No One Can Replace Are Running Out of Inventory
Southern Silver caps successful 23-hole drill program at Puro Corazon, setting the stage for a major resource upgrade at Cerro Las Minitas.

The most recent news (April 1, 2026) reports the final assay results from a 23-hole drill program at the Puro Corazon claim, part of the flagship Cerro Las Minitas (CLM) project in Durango, Mexico. Key intercepts include 4.6 meters of 557g/t AgEq and 9.3 meters of 234g/t AgEq. These results confirm that mineralization extends laterally by 400m and vertically to 500m depth, transitioning into the main CLM block. The company has demobilized drill crews and is now transitioning to technical studies, including an updated Mineral Resource Estimate (MRE) and a revised Preliminary Economic Assessment (PEA).
The news is Routine - Positive. While the grades are high (including "bonanza" silver grades), they are consistent with the steady stream of positive results released throughout Q1 2026 (Jan 6, Jan 27, Feb 9, and March 19). The market was already aware of the program's success; this release simply marks the completion of the data collection phase. - Resource Growth: The results successfully "upgraded" mineralization and identified shallow high-grade lenses that were not in the previous July 2024 PEA. - Economic Implications: The integration of Puro Corazon is expected to improve the "front-end" of the mine plan, potentially increasing the Internal Rate of Return (IRR) by accessing higher-grade ore earlier in the project life. - Execution: Management has met its timeline for completing the 2025-26 drill program and is moving directly into the resource modeling phase.
Southern Silver is a Canadian explorer focused on the Cerro Las Minitas (CLM) project in Durango, Mexico. CLM is one of the largest undeveloped silver-lead-zinc deposits in the world. The project is characterized by skarn and carbonate replacement deposits (CRD) surrounding a central intrusion. The recent focus has been the acquisition and integration of the Puro Corazon claim, which adds high-grade, near-surface mineralization to the existing resource base.
