Rainbow Rare Earths Achieves Breakthrough in Phalaborwa Project with Cerium Depletion

Rainbow Rare Earths (LSE:RBW) has announced major progress at its Phalaborwa project following the successful application of a cerium depletion process. This development improves the grade of its mixed rare earth product while lowering production costs, strengthening Phalaborwa’s position as a competitive, low-cost supplier of critical rare earths. The advancement supports the company’s ambition to become a key contributor to the green technology supply chain and is expected to positively influence both market positioning and stakeholder confidence.

The company’s near-term outlook, however, is still shaped by its financial challenges. With no revenue generation to date and continuing losses, Rainbow faces considerable risks. Even so, technical signals point to bullish momentum, bolstered by the progress of strategic initiatives like Phalaborwa. While its valuation remains difficult due to negative earnings, the company’s growth pipeline and project milestones provide a degree of optimism for investors.
