Integrated Remote Sensing and GIS Analysis for Uranium Exploration: A Case Study of the Falea Deposit, Taoudeni Basin, Mali This study presents a uranium exploration methodology applied to the Falea polymetallic deposit (U-Ag-Cu) in the Taoudeni Basin, western Mali. By combining Landsat-8 OLI satellite imagery, spectral indices, principal component analysis (PCA), and fuzzy logic, the study maps hydrothermal alterations (iron oxides, clay minerals) linked to the structural control of mineralized zones. The resulting prospectivity map confirms known mineralized areas and identifies a new high-potential zone in the northwest of the study area, previously unexplored. This reproducible, low-cost approach can be scaled to other intracratonic basins across Africa.
