We dive deep into the structural geology and tectonic forces of the Eastern Cordillera, offering high-value data for ore prospectors, students of earth science, and the wider geological community (Alicanto Mining Corp., 2026). The Rionegro Project is defined by a sophisticated horst-graben structural framework developed over a marine basin of Jurassic to Tertiary age, which acts as a primary trap for polymetallic mineralization (Alicanto Mining Corp., 2026). A critical highlight of this study is the SGS metallurgical testwork, which confirms a robust endowment of total rare earth (TRE) elements, demonstrating that elements like Lanthanum and Cerium respond exceptionally well to Wet High Intensity Magnetic Separation (WHIMS) with a more than two-fold enrichment relative to the feed (Valls, 2025). Furthermore, the investigation reveals a "geological Trojan horse" where a massive resource of gold is encapsulated within magnetite grains; while this gold was previously lost to tailings in semi-artisanal operations, new mixed chloride leaching technology achieves a gold recovery rate of up to 97% (Alicanto Mining Corp., 2026; Cruz Martín, 2025). By integrating lineament analysis, Ground Penetrating Radar (GPR), and machine learning algorithms, we can systematically identify high-priority drill targets at cross-structural intersections that were previously invisible to traditional prospecting (Galkin, 2026). This video serves as a strategic blueprint for using geophysical parameters such as radiometry and kappametry to de-risk exploration and quantify the inferred mineral resources of complex paleoplacer systems (Alicanto Mining Corp., 2026; Galkin, 2026).
