IMC Rare Earths Reports 73% In-Situ Recovery at Itarantim

We are a mineral exploration and development company, and our main rare earth element (or “REE”) project is the Itarantim Project located in the States of Bahia and Minas Gerais, Brazil. Drilling on this ionic adsorbed clay (“IAC”) REE deposit has identified a mineral resource of 1.1 billion MT with an average grade of 1,233 ppm total rare earth oxides (“TREO”). We have no operating revenues and do not anticipate generating revenues for the foreseeable future. We were incorporated on September 19, 2025 in the Cayman Islands as IMC Rare Earths Ltd. We are developing rare earth mining projects in Brazil with a focus on exploration, development and long-term supply of certain REEs. We are seeking to establish one of the largest high-grade magnet rare earth element (or “MREE”) deposits outside of China and Myanmar, with the ability to supply to rare earth metal markets in the United States and Europe. Based on our exploration results to date, we believe we have the potential to integrate the Itarantim Project into an emerging U.S. rare earth supply chain by supplying our target markets’ growing demand for MREOs.
