Should Western governments prioritize domestic rare earth mineral production over cheaper imports from China?
Rainbow Rare Earths reported an annual loss of US$7.5 million for the financial year ending June 30, 2026, amid concerns regarding future funding requirements. The firm, which recovers elements from phosphogypsum waste, currently maintains US$12.9 million in cash.
Why it matters
The company faces growing financial pressure as it develops rare earth extraction projects in South Africa and Brazil to hedge against export controls from China. Increased losses and a disclosed going-concern uncertainty highlight the capital-intensive nature of securing alternative supply chains.
Rainbow Rare Earths posted an annual loss of US$7.5 million compared to US$3.2 million the prior year. The company finished the 2026 financial year with US$12.9 million in cash, supported by an £11.1 million equity placing completed in April 2026.
The players
Rainbow Rare Earths
An exploration and development company focused on recovering rare earth elements from industrial waste.
Neo Performance Materials
A global processor and developer of rare earth and magnetic materials acting as a technical and offtake partner.
The details
Rainbow Rare Earths recovers rare earth elements from the phosphogypsum waste products of fertilizer production, a method designed to bypass traditional mining constraints. To advance its operations, the company has partnered with Neo Performance Materials for technical expertise and product offtake. The reported annual loss was primarily driven by a non-cash revaluation of an Ecora royalty liability.
Timeline
April 2026: Company completed an £11.1 million equity placing.
June 30, 2026: End of the company's financial year.
Q4 2026: Expected publication of Phalaborwa pre-feasibility study.
H1 2027: Expected release of definitive feasibility study.
Q3 2027: Expected requirement for additional funding.
Market Landscape
The company's expansion into South Africa and Brazil is a direct response to global supply chain vulnerabilities caused by tightening Chinese export controls. This strategy aligns with the broader industry effort to establish rare earth processing sites independent of existing market dominance.
Operators in the battery and permanent magnet supply chains should monitor the company's Q3 2027 funding milestone as an indicator of viability for alternative rare earth sources. Future project feasibility results will determine whether this extraction model offers a reliable long-term procurement hedge.
The takeaway
Companies should treat the going-concern uncertainty at Rainbow Rare Earths as a signal of the high capital hurdles inherent in developing non-traditional rare earth supply chains. Business leaders should track the upcoming Phalaborwa pre-feasibility study in Q4 2026 to evaluate potential future supply availability.
What happens next
Rainbow Rare Earths expects to publish its Phalaborwa pre-feasibility study in the fourth quarter of 2026, followed by a definitive feasibility study in the first half of 2027.
