Pinnacle Silver finds epithermal system at Potrero

Executive Summary

• Pinnacle Silver and Gold Corp. identified a new, robust low‑sulphidation epithermal vein (“El Capulin”) at the Potrero project, extending mineralization ~200 m southwest of the historic Dos de Mayo vein.
• Surface and underground sampling revealed high‑grade gold–silver intercepts, including up to 6.27 g/t Au and 99 g/t Ag over 0.45 m on El Capulin, and vertical extensions of existing veins up to 80 m (elevations 1,490–1,570 masl).
• The expanded strike length now totals ~500 m (potentially 1,600 m traced) with a combined vertical zone of mineralization suggesting significant upside for near‑term production and future development.

Key Details

• El Capulin Vein – NW‑SE trending, mapped 375 m along strike; crystalline quartz vein with lattice‑bladed texture; azimuth ~325°, dip 65°–85° NE; width 45–60 cm (or series of 1–5 cm veinlets up to 2 m).
• Highest Assay on El Capulin: 6.27 g/t Au and 99 g/t Ag (0.45 m sample); lowest 0.117 g/t Au. 36 samples taken to date.
• Vertical Extension of Existing Veins:
• Dos de Mayo: surface grab 9.9 g/t Au, 1,444 g/t Ag over 0.35 m; extends from 1,490 masl to 1,570 masl (80 m).
• Pinos Cuates: channel up to 37.4 g/t Au, 755 g/t Ag over 1.2 m; underground El Jabali up to 36.4 g/t Au, 1,029 g/t Ag over 1.4 m; vertical span 45 m (1,520–1,565 masl).
• Strike Length: Combined Dos de Mayo and Pinos Cuates veins ≈325 m; El Capulin adds ~150 m potential extension → total ≈500 m (traced to 1,600 m overall).
• Exploration Gap: ~120 m between Dos de Mayo and Pinos Cuates with no outcrop exposure; target for future drilling.
• QA/QC: Samples processed by SGS Mexico under ISO/IEC 17025:2017; fire‑assay with AAS finish (code GA_FAA30V5) and ICP‑OES (code GE_ICP40Q12). Certified reference material and blanks inserted per standard protocol.
• Qualified Person: Jorge Ortega, PGeo, independent QP under NI 43‑101, reviewed and approved technical information.

Notable Quotes

“We are extremely pleased with how the combination of underground and surface sampling is coming together to define a strong, well‑defined and high‑grade vein system at El Potrero,” – Robert Archer, President & CEO.

“The higher silver grades at surface continue to suggest there may be some vertical zonation… these observations are consistent with low sulphidation systems in the Topia district and bode well for the potential to develop significant zones of mineralization.” – Robert Archer.
