Algo Grande Reports Results from Completed Phase I Drill Program at Cerro Grande Skarn

Executive Summary

• Phase I drill program at the Cerro Grande Skarn target intersected multiple high‑grade copper‑silver‑gold zones, including a standout intercept of 18.2 m @ 1.8 % CuEq (1.2 % Cu, 28.2 g/t Ag, 0.7 g/t Au) and 3.5 m @ 3.9 % CuEq.
• Five distinct skarn horizons were identified (three newly discovered), confirming a vertically stacked, multi‑horizon skarn system that remains open laterally and at depth with clear porphyry‑related molybdenum vectors.
• Total of 104.76 m above 0.8 % CuEq intersected across the four holes; Phase II drilling slated for May 2026 to expand the footprint, test deeper porphyry targets, and pursue district‑scale exploration.

Key Details

• Drill Program Scope: 4 holes (AG_GC_001‑004), total 1,998 m drilled between 23 Nov 2025 – 4 Feb 2026.
• Core Recovery: >95 % average; high confidence in assay reliability.

Significant Intercepts

• Overall Continuity: 104.76 m above 0.8 % CuEq across all four holes (includes skarn and wall‑rock mineralization, internal dilution).

Skarn Horizons

• Five distinct horizons identified; three are newly discovered during Phase I.
• Horizon stacking increases vertical extent and potential tonnage versus a single‑horizon model.

Metal Zonation & Molybdenum Vectors

• Molybdenum: Notable intervals – AG_GC_002: 1.04 m @ 1,440 ppm Mo; 0.8 m @ 2,820 ppm Mo; AG_GC_004: 0.9 m @ 521 ppm Mo.
• Molybdenum enrichment spatially separate from peak Cu‑Ag‑Au skarn zones, indicating proximity to a deeper porphyry source.

Exploration Implications

• Confirms outcropping, vertically extensive skarn system with surface exposure.
• System open laterally along a 6 km corridor and at depth; vectors point toward potential porphyry intrusion.
• Phase II (starting May 2026) will focus on step‑out drilling, deeper porphyry targets, and new district‑scale targets identified from upcoming LiDAR, drone magnetic surveys, and systematic soil geochemistry.

QA/QC Summary

• Samples analyzed at ALS Laboratories (Hermosillo & Vancouver) using CRU‑31, SPL‑31, PUL‑31 prep methods; ME‑MS61L multi‑element digestion; AU‑AA24 fire assay for gold.
• Internal QC inserts (blanks, standards, duplicates) met acceptable limits; blind QC program also employed.

Qualified Persons

• João Rocha, EurGeol, VP Exploration – reviewed all current and historical drilling data.
• Enrico Gay, CEO – provided forward‑looking commentary on exploration strategy.

Additional Corporate Notice

• OTC symbol changed from KNDYF to ALGRF effective 1 Apr 2026; TSX‑V symbol remains ALGR.

Notable Quotes

“These results validate our thesis that the Cerro Grande Skarn has the potential to scale into a large, high‑grade skarn system… With Phase I complete, we are now advancing toward Phase II drilling…” – Enrico Gay, CEO, Algo Grande Copper Corp.
