Rare Earth Americas sees leach recovery boost at Alpha project in Brazil
Laboratory testing achieved approximately 40% rare earth leach recovery compared with the 27% recovery assumption in Alpha’s Technical Report Summary.
Rare Earth Americas, a company with a focus on rare earth elements, reported on Tuesday that its Alabama project in Brazil demonstrated promising metallurgical test results. The SGS Geosol laboratory conducted tests and discovered approximately 40% rare earth leach recovery, excluding cerium, which is a notable 48% improvement compared to their initial technical report's assumption of 27% recovery under differing conditions.
This project, known as Alpha, is located in Bahia, Brazil and is estimated to possess 202 million tonnes of inferred mineral resource at 1,520 ppm total rare earth oxides with a 1,000 ppm TREO cut-off. The inferred resources, which are not yet proven to be economically viable, include significant amounts of magnet rare earths (neodymium and praseodymium) and dysprosium and terbium.
Rare Earth Americas is working on a diverse portfolio of high-grade heavy rare earth projects, including Alpha, which they believe could secure their position as a significant non-Chinese supplier. The company's CEO, Donald Swartz, expressed optimism about the test results, stating that they provide critical technical input towards evaluating the potential development of Alpha.
The SGS tests revealed that the Alpha composite contained approximately 37% of rare earth elements, excluding cerium, with heavy rare earths making up around 29%. Following the announcement, Rare Earth Americas' stock price experienced a decrease of 5% at the market close in New York.
