Meteoric Resources Limited is an Australian mineral exploration and development company specializing in rare earth elements. Headquartered in West Perth, Western Australia, and listed on the Australian Securities Exchange under the code MEI, the company focuses on advancing its flagship Caldeira Rare Earths Project, a large-scale ionic absorption clay deposit in the southwest region of Minas Gerais state, Brazil, near Poços de Caldas.
The Caldeira Project comprises 77 licenses covering over 193 square kilometers and features a substantial mineral resource exceeding 1.6 billion tonnes. A definitive feasibility study completed in 2026 outlines plans for a low-cost operation producing mixed rare earth carbonate (MREC) products, with average annual output including significant volumes of magnetic rare earths such as neodymium-praseodymium (NdPr) and dysprosium-terbium (DyTb). The project benefits from favorable metallurgy, access to renewable energy, and sustainable practices that avoid traditional tailings dams.
Meteoric Resources Limited operates primarily through Brazilian subsidiaries and has pursued offtake and partnership agreements, including a 2026 memorandum of understanding with POSCO International for long-term supply of rare earth raw materials. The company positions itself as an emerging supplier contributing to diversified global rare earth supply chains outside China, with emphasis on low capital intensity and environmental responsibility. In 2026, it was subject to an acquisition proposal by Lynas Rare Earths.
