Mosaic and Rainbow Rare Earths entered a joint project development agreement to advance the Uberaba rare earths project in Minas Gerais, Brazil. Under the agreement, the companies will jointly pursue a prefeasibility study, with the intention of moving to a definitive feasibility study later in 2026. If the studies support proceeding, the parties expect to negotiate definitive agreements for a jointly owned project company and target construction of a processing facility in Uberaba starting in 2027. The preliminary economic assessment indicates an onsite facility would process about 2.7 million tonnes per year of phosphogypsum and produce 1,900 tonnes of separated NdPr oxide. The assessment also estimates output of 600 tonnes of an SEG+ product, with initial production targeted for 2030.
