St George Mining Ltd. has extended its strategic alliance with U.S.-based REalloys over the high-grade rare earths resource at the company’s Araxá project in Minas Gerais, Brazil.
The original agreement, which was first announced in September 2025, envisaged an offtake agreement being entered into within 120 days of the signing of the memorandum of understanding.
The two companies decided to extend the period by one year to allow for more detailed metallurgical test work and flow sheet development to be completed.
REalloys is continuing metallurgical test work on samples of rare earths from Araxá. The results of the test work will guide the optimisation of the processing flowsheet for the production of rare earth products at the project.
Both companies are still collaborating to commercialise the rare earths at Araxá, with a view to REalloys securing a long-term offtake contract for up to 40 per cent of the rare earths production from the project.
John Prineas, St George’s Executive Chairman, said: “We are excited to be continuing our collaboration with an industry leader like REalloys – an alliance that has the potential to provide an attractive pathway for St George to access the rapidly developing and lucrative downstream sector of the U.S. rare earths industry.
“The Araxá project boasts a world-class, hard-rock rare earths resource with scale that makes it well-positioned to be a potential supplier of rare earth products for ex-China supply chains being established in Brazil, the U.S. and other countries.”
REalloys has a vertically integrated rare earths processing platform focused on North American supply chain independence. The company has industry-leading technical capabilities in rare earths processing with deep experience and proprietary technology in rare earths separation and metallisation.
St George’s Araxá project is potentially a world-class rrare-earth and niobium project in Brazil.
The region around the project has a long history of commercial niobium production and provides access to infrastructure and a skilled workforce.
