Rainbow Rare Earths Ltd (LSE:RBW) has reported continued progress in efforts to streamline development costs at its flagship Phalaborwa project in South Africa. The company’s in-house laboratory in Johannesburg—equipped with advanced analytical tools—has now been fully operational for three months, enabling faster and more economical test work. Ongoing laboratory studies and trade-off analyses are focused on optimizing the leaching circuit, increasing rare earth element recovery, and refining the purification process.
These initiatives aim to strengthen the project’s economic viability and establish Phalaborwa as a reliable, low-cost source of magnet rare earths. Given the global demand for these critical materials, especially in the clean energy and high-tech sectors, this progress could significantly enhance supply chain resilience and cost efficiency.
Although Rainbow Rare Earths continues to face financial headwinds—characterized by ongoing losses and the absence of revenue—technical indicators suggest strong upward momentum in the company’s stock. Strategic assets like Phalaborwa are contributing to investor optimism, even as valuation remains a challenge due to negative earnings.
