Andina Copper begins field exploration at Cobrasco

Executive Summary

• Andina Copper Corp. has begun field exploration across the Cobrasco porphyry copper‑molybdenum project in Chocó, Colombia, including surface work at Cobrasco East and mobilizing a drill crew for Cobrasco Central.
• Historical drilling at Cobrasco Central intersected significant Cu‑Mo mineralization; the new program aims to delineate size and grade of this discovery while advancing multiple adjacent targets (East, North, South, Southern Block).
• Management emphasizes that Cobrasco is a “company‑making” asset and highlights upcoming 2025/2026 field programs at other projects (Piuquenes in Argentina and Mantau in Chile).

Key Details

• Project Scope: Cobrasco covers ~3,000 ha (30 km²) within the underexplored Chocó copper belt of Colombia’s western cordillera.
• Historical Drilling at Cobrasco Central:
• Hole 1 – 1,046.40 m depth; significant Cu‑Mo intercepts.
• Hole 2 – 941.60 m depth; significant Cu‑Mo intercepts.
• Hole 3 – terminated at 300.60 m; also intersected mineralization.
• Mineralogy: Bornite‑dominant with chalcopyrite and molybdenite; low arsenic penalties.
• Geochemical Highlights: Rock assays >0.3 % Cu and >100 ppm Mo across the central tenement; soil auger grid 100 × 80 m (infilled to 50 × 80 m) shows multielement support.
• Cobrasco East – Surface Sampling Results:
• Float sample assay up to 5.38 % Cu.
• Possible outcrop sample assay up to 0.92 % Cu.
• Exploration Activities (Current Program):
• Reconnaissance mapping and rock‑chip sampling at Cobrasco East, North, South, and Southern Block.
• Restart of stream‑sediment sampling in second‑ and third‑order streams to define anomalism extent.
• Mobilization of a drill crew to test the size/grade potential of Cobrasco Central porphyry.
• Future Work: Plans for broader property‑wide surface sampling and multielement characterization; continuation into the 2025/2026 field season at Piuquenes (Argentina) with geophysics and discovery drilling.
• Management Quote (CEO Joseph van den Elsen): Emphasizes Cobrasco as a “company‑making asset,” outlines strategy to create shareholder value through multi‑asset news flow, and notes upcoming results from the Mantau surface sampling program in Chile.
