Southern Silver Drills 4.6 Metres Averaging 201 G/T Ag, 4.5% Pb and 9.8% Zn (557 G/T AgEq) at Puro Corazon Claim, Mexico

Why It Matters

These high‑grade intercepts improve the grade profile of Cerro Las Minitas, supporting a larger, more economically robust underground mine and potentially accelerating early cash flow. The data also de‑risks the project, positioning Southern Silver for a stronger PEA and future financing.

Key Takeaways

• 4.6m interval 201 g/t Ag, 4.5% Pb, 9.8% Zn.
• 1.5m interval 401 g/t Ag, 8.9% Pb, 22.3% Zn.
• 9.3m interval 62 g/t Ag, 6.0% Zn.
• Mineralization extends 400m laterally, 500m depth.
• Results will drive updated resource estimate and PEA.

Pulse Analysis

The newly released assays from Southern Silver’s Puro Corazon drilling underscore a surge of high‑grade polymetallic mineralization that could reshape the economics of its flagship Cerro Las Minitas project. In a market where silver prices have shown resilience, intercepts delivering over 500 g/t AgEq are rare and immediately boost the projected net‑present value of the underground operation. By confirming both skarn‑type and replacement‑style mineralization, the drill program validates a diversified ore body that can support flexible processing options and mitigate commodity‑specific risk.

Geologically, the Puro Corazon claim sits within Durango’s prolific Faja de Plata corridor, an area renowned for world‑class silver‑lead‑zinc systems such as Penasquito and Naica. The discovery of bonanza‑grade, shallow replacement lenses just 200 metres below surface expands the known halo of the main intrusion, extending laterally over 400 metres and vertically to 500 metres depth. This geometry suggests a potential high‑grade, low‑cost mining envelope that could be accessed early in a mine plan, reducing initial capital outlay and accelerating cash‑flow generation compared with deeper, bulk‑tonnage zones.

From a corporate perspective, integrating these results into an updated NI 43‑101 resource estimate and a revised Preliminary Economic Assessment positions Southern Silver to attract strategic investors and secure financing on more favorable terms. The enhanced resource metrics are likely to improve the project’s internal rate of return and extend its mine life, while the ongoing baseline studies—hydrology, geotechnical, and permitting—demonstrate a disciplined de‑risking approach. Collectively, the data reinforce Southern Silver’s claim as a high‑potential, multi‑metal platform in a mining‑friendly jurisdiction, potentially lifting its valuation ahead of the next financing round.
