Monte Alto Metallurgical Results Successfully Deliver High-Purity MREC and Yellowcake Product

Core Insights - Brazilian Rare Earths Limited (BRE) has successfully produced a mixed-rare earth carbonate (MREC) and uranium peroxide from the Monte Alto Project, marking a significant milestone in establishing a fully integrated rare-earths and critical-minerals supply chain in Brazil [1][3]. Metallurgical Highlights - The completion of the second phase of metallurgical test work with ANSTO Minerals has validated BRE's development strategy [3][5]. - High-purity MREC production meets quality specifications for conventional solvent-extraction separation circuits [6]. - Strong recoveries of magnetic rare earth elements NdPr and DyTb achieved, with total rare-earth oxide (TREO) extraction rates between 86-90% [6][7]. - Successful extraction of uranium with the precipitation of uranium peroxide, enhancing the product strategy [6][8]. - Direct 'run-of-mine' mineral-to-MREC route provides capex and opex advantages, increasing total rare-earth yields [6][7]. - Ongoing metallurgical studies aim to produce separated NdPr rare earth products and recover valuable co-products like niobium, tantalum, and scandium [6][9]. Product Strategy - The company targets four high-value products: NdPr oxide, a heavy rare earth-rich SEG+ concentrate, uranium, and a valuable co-product stream including niobium, scandium, and tantalum [8][9]. - The SEG+ product is particularly rich in critical elements such as dysprosium, terbium, samarium, gadolinium, and yttrium, which are essential for advanced industries [10][11]. Strategic Advantages - Brazil's unique location offers structural cost advantages for downstream processing due to abundant low-cost hydroelectric power, skilled labor, and domestic reagent supply [9][11]. - The exceptional chevkinite-rich mineralogy of Monte Alto reinforces confidence in unlocking shareholder value through low-cost leaching and conventional solvent-extraction methods [11].
