About Rainbow:

Rainbow Rare Earths aims to be a forerunner in the establishment of an independent and ethical supply chain of the rare earth elements that are driving the green energy transition. It is doing this by developing projects that recover rare earth elements from phosphogypsum, a by-product of fertilizer production. This approach avoids traditional mining and allows projects to be advanced more quickly and at lower cost. The Company is progressing two projects: Phalaborwa in South Africa and Uberaba in Brazil, and these projects are expected to produce critical materials for a wide range of industrial, energy, and defence applications.
