[{"type":"text","content":"August 18, 2025 – TheNewswire - Vancouver, British Columbia - Andina Copper Corporation (Andina) is pleased to announce that as preparations for field mobilization at the flagship Piuquenes and Cobrasco projects advance, the Company has commenced field assessment of the Mantau copper-gold target in the Antofagasta region of northern Chile. Mantau is located in a prolific copper district and adjoins tenements hosting Marimaca Copper’s (TSXV:MARI) recent Pampa Medina Norte sulphide copper discovery1. Mantau Cu-Au Project Highlights: Multiple historical copper workings occur within a 4,500ha tenement package in the low-altitude Coastal Cordillera of Chile (refer Figure 1), one of the world’s premier mining jurisdictions Potential to host stratabound (Manto) and Iron Oxide Copper Gold (IOCG) style copper and gold mineralization Limited previous surface rock chip sampling around historical workings has returned grades up to 28.6% copper and 5.91g/t gold Close proximity to Marimaca Copper’s (TSX-V:MARI) recent Pampa Medina sulphide copper discovery and the Pias target (refer Figure 1). Other noteworthy projects in the near vicinity include Marimaca Copper’s MOD Deposit2 (1mt contained Cu ~ 20km SW) and Antofagasta PLCs Cachorro discovery (~250Mt @ 1.26% Cu, 4g/t Ag ~20km E)3 Excellent access to infrastructure with multiple operating copper mines and development projects nearby. Work Program Summary: Andina has initiated a comprehensive review of historical work, and currently has an exploration team on site conducting reconnaissance mapping and rock chip sampling of historical occurrences and alteration zones defined in ASTER spectral imagery. A detailed geochemical orientation survey to determine optimized future sampling techniques and assay methodology is also being prepared, in addition to drone-based aerial photogrammetry over the extent of the project concessions. Detailed litho-geochemical sampling of all rock types will also be completed to establish background values and pathfinder geochemistry. Evaluation of cost-effective geophysical techniques applicable to the mineralization styles and geology of Mantau and the surrounding district is underway, including detailed (close-spaced) magnetics survey, conducted either via conventional ground-based or aerial (drone) based p...
