AC-REE deposit. These deposits are hosted in thick weathering profiles (locally exceeding 100 m) formed over nepheline syenites and phonolites, where supergene processes promoted the breakdown of primary REE-bearing minerals and subsequent adsorption of REE3+ onto clay mineral surfaces. The Capão do Mel locally exceeding 3,800 ppm TREO with significant proportions of magnet REE (Nd, Pr, Dy, Tb)
