Press Release: Rare Earths Americas Launches Initial Assessment at Constellation in Poços de Caldas Amid Growing Strategic Focus on Brazilian Ionic Clay Rare Earths

Rare Earths Americas, Inc. (NYSE American: REA) has commenced an Initial Assessment ("IA") at its Constellation Rare Earths Project in Brazil's Poços de Caldas district, which hosts an inferred mineral resource of 266.2 million tonnes at 2,637 ppm TREO. Constellation is one of three rare earth projects REA holds in Brazil, alongside the Alpha Project in Bahia and the early-stage Homer-A exploration project in Goiás. Recent activity involving Meteoric Resources' Caldeira Project in Poços de Caldas and Serra Verde's Pela Ema operation in Goiás reflects growing interest in Brazilian ionic clay assets.
