Southern Silver Intersects 4.6 metres Averaging 201g/t Ag, 4.5% Pb and 9.8% Zn (557g/t AgEq) at Cerro Las Minitas Project in Durango, Mexico
Executive Summary
- Southern Silver reports final assay results from the 23‑hole Puro Corazón drill program, highlighting multiple high‑grade silver‑lead‑zinc intercepts that extend mineralization to depth and laterally up to ~400 m.
- Notable intervals include a 4.6 m zone averaging 201 g/t Ag (557 g/t AgEq) and a 1.5 m sub‑zone with 401 g/t Ag (1,181 g/t AgEq); plus a 9.3 m interval of 62 g/t Ag (234 g/t AgEq) with a 2.2 m high‑grade core of 135 g/t Ag (522 g/t AgEq).
- The company will incorporate these results into an updated Mineral Resource Estimate and a revised Preliminary Economic Assessment for the larger Cerro Las Minitas project.
Key Details
- Drill Hole 26CLM‑221
- 4.6 m @ 201 g/t Ag, 0.1 % Cu, 4.5 % Pb, 9.8 % Zn → 557 g/t AgEq
-
Includes 1.5 m @ 401 g/t Ag, 0.2 % Cu, 8.9 % Pb, 22.3 % Zn → 1,181 g/t AgEq
-
Drill Hole 26CLM‑223
- 9.3 m @ 62 g/t Ag, 0.1 % Cu, 0.2 % Pb, 6.0 % Zn → 234 g/t AgEq
-
Includes 2.2 m @ 135 g/t Ag, 0.2 % Cu, 0.4 % Pb, 13.5 % Zn → 522 g/t AgEq
-
All 23 planned holes are complete; drill crews have been demobilized.
- Ongoing work: sampling & mapping of historic mine workings (13 levels, >1,300 samples collected); assay results to be released in coming weeks.
- Mineralization now traced laterally up to ~400 m and vertically to ~500 m depth, transitioning into the larger CLM claim block.
- Identification of “bonanza‑grade” replacement‑style intercepts near surface (~200 m) suggests potential for early‑stage shallow mining.
Next Steps
1. Update the Mineral Resource Estimate for Cerro Las Minitas incorporating new drill data.
2. Revise the Preliminary Economic Assessment (PEA) per NI 43‑101 standards.
3. Continue baseline data collection, permitting readiness, and ancillary studies (hydrology, geotechnical, archaeological, land surveys).
The company cites prior July 2024 PEA economics as a baseline for evaluating the impact of these new results.
Notable Quotes
“The 2025‑26 drill program successfully outlined and upgraded mineralization on the Puro Corazón claim… More significantly, drilling also intersected multiple bonanza‑grade, replacement‑styled intercepts… potentially forming a shallow high‑grade lens outboard of the main skarn zone.” – Rob Macdonald, Vice President of Exploration
