Kobrea Discovers Large Hydrothermal Breccia Body in Cuprum Trend - Western Malargue Mining District - Mendoza Province, Argentina

Executive Summary

• Kobrea Exploration Corp. announced the discovery of a large (1,250 m × 500 m) hydrothermal breccia body at Target KBX‑17 within its Western Malargüe Copper Projects in Mendoza Province, Argentina.
• Geochemical sampling shows anomalous copper values up to 1.6 % Cu in host diorite and 161–408 ppm Cu within the breccia, with additional smaller breccias (300 m × 150 m) grading up to 223 ppm Cu.
• The company plans an Induced Polarization (IP) survey to test for a deeper porphyry system and will continue systematic geological mapping and sampling across the property.

Key Details

• Target KBX‑17 location: 8 km from existing road; first identified March 2025 via colour anomaly on a 4×4 road.
• Breccia dimensions: 1,250 m (length) × 500 m (width); cemented by iron oxides and locally massive pyrite.
• Copper anomalies:
• Breccia samples: 161–408 ppm Cu.
• Adjacent diorite host rock: up to 1.6 % Cu.
• Smaller magnetite‑cemented breccia (300 m × 150 m): up to 223 ppm Cu.
• Geology: Breccia intrudes a 4 km × 2 km equigranular diorite stock showing propylitic alteration; the diorite cuts upper Jurassic Tordillo Formation sediments.
• Exploration program to date:
• Detailed geological mapping and rock‑chip sampling completed Dec 2025.
• QA/QC performed by Alex Stewart International (ISO/IEC 17025:2017 accredited).
• Future work: Planned Induced Polarization survey over KBX‑17; continued systematic mapping, geochemical sampling, and drilling at El Destino porphyry Cu‑Au prospect and other targets across the Western Malargüe Copper Projects.
• Qualified Person: Rory Ritchie, P.Geo., VP – Exploration & Director (NI 43‑101).
