The $1.8T Energy Sprint: Why America is Betting Big on Strategic Mineral Platforms
Bonanza Grades at Puro Corazon Validate Strategic Acquisition as Project Economics Head for Re-Rating
The news from January 15, 2026, and its predecessor on January 6, 2026, reports high-grade drilling results from the recently acquired Puro Corazon claim at the Cerro Las Minitas (CLM) project in Durango, Mexico. Notable intercepts include 10.4 metres (true thickness) averaging 743 g/t AgEq and 3.9 metres at 1,490 g/t AgEq. These results represent a significant 65-metre step-out from previously reported mineralization. The company has completed approximately 6,820 metres of a planned 12,000-metre diamond drilling program. Management confirms that these results demonstrate continuity with the El Sol deposit and extend mineralization into previously untested areas.
The impact of these results is Material - Positive for several reasons: - Integration Success: The acquisition of the 9-hectare Puro Corazon claim in late 2025 was a tactical move to consolidate a high-grade, near-surface portion of the Skarn Front deposit that was previously "locked" by third-party ownership. - Economic Re-rating: The current CLM project model (based on the July 2024 PEA) did not include this high-grade material. Incorporating bonanza-grade silver (up to 1,490 g/t AgEq) into the early years of a mine plan could significantly improve Net Present Value (NPV) and Internal Rate of Return (IRR) by reducing payback periods. - Continuity: Proving that mineralization extends 65 metres beyond known boundaries suggests the resource is larger than currently modeled. - Cash Position: The company is well-funded following a C$15M raise in July 2025 and a C$6M raise in December 2025, allowing them to complete the remaining 5,000+ metres of drilling without immediate dilution.
Southern Silver is an exploration and development company focused on the Cerro Las Minitas project in Durango, Mexico. CLM is one of the largest undeveloped silver-lead-zinc deposits globally. The project is characterized by skarn-style mineralization around a central monzonite intrusion. The July 2024 PEA outlined a large-scale underground mining operation, but the recent acquisition of the Puro Corazon claim and the Nazas property expansion indicates a pivot toward higher-grade, near-term production scenarios.
