Cobrasco is a company-making asset, and our focus is on defining the size and grade potential of the initial discovery at Cobrasco Central and concurrently advancing other highly prospective targets along the Eocene porphyry belt, including Cobrasco East. Since completing the acquisition of Cobrasco and closing an upsized financing in July 2025, we have moved quickly to build out our local team and recommence field exploration.

This is an exciting time to be an Andina Copper shareholder as we commence concurrent field activities across our portfolio of high-quality copper and copper-gold discoveries. Surface exploration is underway at Cobrasco, and preparations are well advanced for the 2025/26 field season at our Piuquenes copper-gold project in San Juan, Argentina, where project wide geophysics and new discovery drilling is planned

Results from a surface sampling program recently completed to assess the potential of the Mantau copper-gold project in Antofagasta, Chile (refer 18 August 2025 News Release) are also expected shortly.
