Montero Completes Exploration Programs at Potrero Gold Project and Advances Data-Driven Targeting Strategy

Core Viewpoint - Montero Mining and Exploration Ltd. has completed a comprehensive data compilation and exploration program at its Potrero gold project in Chile, utilizing advanced data analytics and machine learning techniques to enhance geological understanding and identify potential mineralization areas [1][9]. Project Overview - The Potrero Project is situated approximately 50 km southeast of El Salvador and 20 km north of Kinross' La Coipa gold-silver mine, within a well-established mining district that includes notable projects like Kinross' Lobo mine and Gold Fields' Salares Norte gold mine [2]. - The project encompasses a contiguous package of mining concessions that cover the interpreted hydrothermal alteration footprint and structural corridors identified to date [2]. Exploration Program - The exploration program aimed to refine the geological and structural understanding of the hydrothermal system and assess its potential for gold mineralization at depth [6][8]. - Key components of the program included the compilation of historical exploration data, ASTER and Sentinel-2 imagery analysis, detailed geological mapping at a 1:10,000 scale, and high-resolution surface geochemical sampling using four-acid digestion ICP-MS methods [7][8]. Historical Exploration - Historical exploration at Potrero has included geological mapping, surface sampling, geophysical surveys, and drilling programs by various companies over the past decade, with significant early work conducted by Verde Resources Inc. [10][11]. - Verde's exploration identified gold mineralization with drill intercepts such as 126 meters grading 0.44 g/t Au and surface samples returning up to 7 g/t Au [11]. Geological and Structural Mapping - Detailed geological mapping has confirmed the presence of a hydrothermal system within a subvolcanic magmatic setting, characterized by andesitic domes and hydrothermal breccias [15]. - The project area exhibits polydirectional stockwork veining and localized advanced argillic alteration, consistent with porphyry gold systems in the Maricunga Belt [16][17]. Geophysical Programs - The exploration program incorporated historical ground magnetic data and a recent induced polarization (IP) and resistivity survey totaling approximately 28 line-kilometers [19][21]. - The magnetic data, originally acquired in 2012, has been reprocessed for integration with current exploration datasets to support geological interpretation [20]. Geochemical Programs - High-resolution surface geochemical sampling has been completed, and an independent geochemical vectoring analysis is underway to enhance the geological model [23][24]. Data Integration and AI-Assisted Analysis - The company is compiling and integrating geological, geophysical, and historical exploration datasets to support ongoing technical evaluation and three-dimensional modeling of the project [25][26]. Next Steps - Future activities include the reprocessing of historical magnetic survey data, completion of IP and resistivity surveying, and continued integration of datasets to refine geological models and prioritize areas for further exploration [28][29].
