Luca drills 37.2 m of 5.87 g/t Au at Campo Morado

Executive Summary

• Luca Mining released high‑grade intercepts from both surface and underground drill holes at the Campo Morado VMS project, highlighting significant gold, silver and zinc mineralization.
• Notable results include 37.2 m @ 13.85 g/t AuEq (5.87 g/t Au) in surface hole CMRF25‑07 and 5.5 m @ 15.2 g/t AuEq (3.20 g/t Au) in underground hole CMUG‑25‑022, both intersecting substantial zinc and lead grades.
• Phase 1 drilling (≈5,070 m underground, 2,500 m surface) is complete; a Phase 2 program is planned to further test high‑grade targets.

Key Details

• Surface Hole CMRF25‑07: 37.2 m @ 13.85 g/t AuEq (5.87 g/t Au, 367.5 g/t Ag, 0.53 % Cu, 5.54 % Zn, 2.57 % Pb); includes 6.2 m @ 43.77 g/t AuEq (20.81 g/t Au, 1,484.2 g/t Ag, 0.82 % Cu, 5.98 % Zn, 4.58 % Pb).
• Underground Hole CMUG‑25‑022: 5.5 m @ 15.2 g/t AuEq (3.20 g/t Au, 252.6 g/t Ag, 2.19 % Cu, 12.79 % Zn, 5.10 % Pb) located within 20 m of current workings.
• Additional Surface Intercepts:
• 9.9 m @ 28.32 g/t AuEq (11.61 g/t Au, 783.9 g/t Ag, 3.51 % Cu, 4.56 % Zn, 2.91 % Pb) – hole CMRF25‑06.
• 5.0 m @ 9.13 g/t AuEq (3.56 g/t Au, 196.28 g/t Ag, 0.70 % Cu, 4.43 % Zn, 2.24 % Pb) – hole CMRF25‑03.
• 3.9 m @ 19.78 g/t AuEq (11.23 g/t Au, 342.28 g/t Ag, 0.36 % Cu, 3.95 % Zn, 7.55 % Pb) – hole CMRF25‑02.
• Underground Continuity: Holes CMUG‑25‑17, ‑19 to ‑21 confirmed mineralization continuity between Largo and Southwest zones; hole CMUG‑25‑22 extended Bajo zone mineralization above cut‑off grades.
• Drilling Summary: Phase 1 completed 24 underground holes (5,070 m) and 10 surface holes (2,500 m) at Reforma and El Rey deposits.
• Future Plans: Phase 2 surface drilling targeting additional high‑grade gold to commence shortly; continued underground and near‑mine exploration planned.
• QA/QC: Samples analyzed by Bureau Veritas using multi‑acid digestion ICP‑ES and fire assay methods with robust standards, duplicates and blanks.
