Brazil represents one the few sources of large-scale high-grade rare earths supply which can help reduce reliance on China. There are a number of rare earths projects globally, but none compare to IMC when considering scale, rare-earths product mix, location and team. Furthermore, most of these other projects are more weighted towards light rare earths (NdPr).

The growing demand for clean energy technologies and advanced electronics is significantly shaping the market for heavy rare earth elements (HREEs).
Heavy magnet rare earths (HREEs), particularly dysprosium (Dy) and terbium (Tb), are considered the linchpin of next-generation electric vehicles (EVs) and wind turbines due to their crucial role in enhancing the performance and reliability of neodymium-iron-boron (NdFeB) permanent magnets. They improve the thermal stability and provide demagnetization resistance. These magnets are the backbone of high-efficiency motors and generators essential for these technologies.
Heavy elements such as Dysprosium and Terbium enhance heat resistance and stability in permanent magnets. While alternatives like ferrites or alnico magnets exist, they fall short in terms of strength, size, and heat resistance. This enables cutting-edge aerospace, defence, and electronics applications where reliability is paramount.
Rare earth elements are critical to modern technology, from smartphones to renewable energy systems. However, not all rare earths hold equal significance.
Magnet rare earths like neodymium, praseodymium, dysprosium, and terbium are vital for high-performance magnets, with this opportunity focusing on their strategic value and essential supply chains.
