Andina Copper Reports up to 9.43% Cu and 2.2 g/t Au from Rock-Chip Samples at Mantau, Antofagasta, Chile

Core Insights - Andina Copper Corporation has reported significant findings from its initial geological field evaluation and sampling program at the Mantau copper-gold project in northern Chile, validating historical high-grade results and expanding the area of interest [1][2][4] Group 1: Project Highlights - The Mantau project has confirmed historical rock chip samples with grades up to 28.6% Cu and 5.91 g/t Au, with recent sampling returning five additional assays greater than 1% Cu and eight greater than 0.1 g/t Au [1][4][10] - A drone-based photogrammetry survey has produced a high-resolution Digital Elevation Model (DEM) to support further mapping and geophysical studies [2] - The project area is located within a highly prospective district that includes significant deposits such as Marimaca Copper's MOD Deposit (200 million tonnes at 0.45% Cu) and Antofagasta PLC's Cachorro discovery (300 million tonnes at 1% Cu, 4 g/t Ag) [4] Group 2: Geological Findings - The geological review identified multiple lithologies and alteration zones consistent with IOCG-style mineralization, with mineralization primarily localized along the Falla Este fault zone [8][9][10] - Recent sampling confirmed the presence of copper oxides and other mineralization indicators, with significant results including 9.43% Cu and 0.21 g/t Au from sample 16680 and 9.32% Cu and 0.40 g/t Au from sample 16731 [10][11] Group 3: Future Exploration Plans - The company is planning a follow-up exploration program that will include grid-based soil sampling and geophysical surveys to define drill targets [2][17] - The next steps will focus on systematic soil geochemical programs and advanced geophysical techniques to gain insights into the subsurface and refine target definitions [17]
