Rare earth element (REE) exploration increasingly relies on remote sensing to reduce search costs, narrow field targets, and improve geological understanding before expensive drilling begins. [SciRep24] [USGS-REE] In practice, the strongest workflows do not depend on a single image or sensor; they combine multispectral mapping, hyperspectral mineral detection, structural interpretation, and GIS-based prospectivity analysis to identify the most promising areas for follow-up.
