Global Push to Secure Rare Earth Supply Chains Amid China’s Dominance and Chemical Export Restrictions

Countries and mining firms are accelerating projects that reduce reliance on China’s near-monopoly over rare-earth refining and the forthcoming restriction on sulphuric-acid exports. Kenya’s Mrima Hill deposit, Lindian Resources’ Kazakhstan sulphuric-acid partnership, and Critical Metals Corp.’s acquisition of European Lithium’s stake in Greenland’s Tanbreez project illustrate a coordinated effort to build alternative upstream and downstream capabilities.

Rare-earth elements (REE) such as neodymium, dysprosium and praseodymium enable high-performance magnets for electric-vehicle (EV) motors, wind-turbine generators and defense guidance systems. Global EV production is projected to reach 40 million units per year by 2030, a demand that could triple magnet requirements. In 2024, China supplied roughly 91 % of refined magnet materials and controls over 80 % of worldwide REE-refining capacity, prompting a “magnet crisis” that drives strategic-mineral policies in the United States, European Union and Japan.

• Kenya – Mrima Hill: The Ministry of Mining, Blue Economy and Maritime Affairs has signaled openness to foreign investment for the Kwale-County deposit, described as one of the world’s largest untapped REE resources.

• Lindian Resources: The company secured a long-term sulphuric-acid supply from Kazakhstan’s state-backed Stepnogorsk plant (SSAP) at US $100-130 per tonne, pre-empting China’s planned export ban of 4.65 million tonnes of acid effective May 2026.

• Critical Metals Corp.: The firm agreed to acquire European Lithium Ltd.’s remaining 7.5 % stake in the Tanbreez project, raising its ownership to 92.5 % and positioning the Arctic deposit as a source of heavy REEs (HREEs) essential for high-temperature magnets.

Kenyan officials emphasize the need for ESG-compliant mining to attract tier-one technology partners. Lindian’s executive director highlighted the strategic value of domestic acid supply for downstream processing. Critical Metals’ chairman described the 92.5 % stake as eliminating a major structural barrier to project financing. U.S. and EU authorities continue to promote “critical minerals acts” that fast-track permits for non-Chinese supply chains.

Environmental groups caution that REE extraction often co-occurs with radioactive thorium, raising long-term remediation concerns. Reliance on a state-backed Kazakh acid source may substitute one geopolitical dependency for another, potentially limiting true supply sovereignty. Kenya’s regulatory framework remains under development, creating uncertainty for investors.

The Mrima Hill project lacks finalized environmental impact assessments, and the Kenyan licensing timeline is not publicly disclosed. Critical Metals’ acquisition still requires shareholder approval, court clearance and a binding agreement, leaving the final ownership structure unresolved. China’s acid export ban timeline is announced, but exact implementation mechanisms remain unspecified.

• “5% stake approval a game-changer for the project, saying it eliminated “the most significant structural overhang.” — Tony Sage, Chairman, Critical Metals Corp.

Kenya is expected to issue mining licences for Mrima Hill within the next year. China’s sulphuric-acid export restrictions will take effect in May 2026, testing the resilience of Kazakh supply contracts. Critical Metals must complete its European Lithium transaction and secure financing before commencing full-scale Tanbreez development. Collectively, these steps will shape the next phase of global rare-earth supply-chain diversification.
