OUTCROP SILVER EXTENDS HIGH-GRADE AT GUADUAL: 2.35 M OF 3,092 G/T SILVER; THREE-RIG PROGRAM ADVANCING RESOURCE EXPANSION

Executive Summary

• Outcrop Silver reported multiple high‑grade drill intercepts from the Guadual vein at its 100 % owned Santa Ana primary silver project in Colombia, including a standout 2.35 m of 3,092 g/t Ag and 4.95 g/t Au (3,463 g/t AgEq).
• The results confirm strike‑ and depth‑continuity of the Guadual North vein system, which remains open in all directions and is being targeted for inclusion in the next mineral resource estimate slated for early 2026.
• A three‑rig drilling program is now active, focusing on infill and step‑out drilling to tighten high‑grade zones, extend depth and strike continuity, and evaluate structural connections with adjacent veins (Jiménez, Aguilar) that together form a >2 km mineralized corridor.

Key Details

• Drill Hole DH493: 2.35 m @ 3,092 g/t Ag & 4.95 g/t Au → 3,463 g/t AgEq.
• Drill Hole DH495: 1.30 m @ 4,587 g/t Ag & 12.30 g/t Au → 5,510 g/t AgEq (highest reported grade).
• Drill Hole DH486: 2.76 m @ 880 g/t Ag & 1.67 g/t Au → 1,006 g/t AgEq.
• Additional notable intercepts: DH495 (incl.) 0.74 m @ 8,022 g/t Ag & 21.53 g/t Au → 9,639 g/t AgEq; DH493 (incl.) 1.06 m @ 4,386 g/t Ag & 3.12 g/t Au → 4,620 g/t AgEq.
• Program Status: Three rigs operating; drilling aimed at tightening high‑grade cores for resource estimation and extending the vein system both laterally and at depth.
• Geological Context: Guadual is a NNE–NE trending, sub‑vertical quartz‑sulfide vein hosting argentite, pyrite, and galena. Surface trenching shows >400 m footprint; Guadual North now identified as a high‑grade core for near‑term resource inclusion.
• Future Work: Continued step‑out & infill drilling on Guadual North; grade‑shell modeling and domain definition underway; exploration of structural links to Jiménez and Aguilar veins to potentially expand the >2 km mineralized corridor.
• Resource Implication: Results are expected to support a “significant expansion” of Santa Ana’s mineral resources ahead of the early‑2026 MRE update.

Notable Quotes

“The results from Guadual continue to exceed expectations… demonstrate potential for significant high‑grade silver resource additions to our upcoming MRE,” – Guillermo Hernandez, Vice President of Exploration.
