en.Wedoany.com Reported, St George Mining Limited (ASX:SGQ, FRA:S0G, OTC:SGQMF) recently entered into a strategic engineering alliance with the Spanish group Técnicas Reunidas SA to strengthen the downstream processing pathway for its Araxá niobium-rare earth project in Minas Gerais, Brazil. The two parties signed a memorandum of understanding to test advanced rare earth processing technologies and assess the potential for market entry into Europe.
Under the agreement, Técnicas Reunidas will conduct metallurgical test work on samples from the Araxá project, focusing on optimizing processing routes and evaluating the applicability of its proprietary RARETECH® technology. This initiative builds upon recent progress at the Araxá project, including a resource increase to 70.9 million tonnes and ongoing high-grade rare earth and niobium intercepts from drilling, helping position the project more favorably within the global critical minerals supply chain.
Técnicas Reunidas brings significant technical and strategic weight to the collaboration. The company is leading the EU-backed PERMANET project, which aims to establish Europe's first integrated rare earth permanent magnet value chain, covering 12 countries and 32 partners, reflecting European efforts to secure independent supplies of critical materials. For St. George, this alliance opens up a potential third major market, running parallel to its existing downstream relationships in the US and Brazil.
John Prineas, Executive Chairman of St. George Mining, stated: "We are very pleased to be working with Técnicas Reunidas to further evaluate the optimal processing route for Araxá's rare earths and the potential entry into the vast European rare earth market." He added that the scale of the Araxá resource, as the largest hard rock rare earth deposit in South America, provides room to supply multiple global markets.
According to the memorandum of understanding, initial work will assess the effectiveness of the RARETECH® process on Araxá mineralization, including the production of mixed rare earth carbonate and rare earth oxides, as well as the separation and splitting of individual rare earth elements. If results are positive, the scope could expand to process optimization, preliminary engineering studies, and cost estimation, with the possibility of a future technology licensing agreement. The agreement is currently non-exclusive, allowing St. George to continue seeking other partnerships while advancing development studies.
This latest move adds momentum to the growth of the Araxá project, as St. George shifts from resource definition to development planning and downstream integration. Located in an established mining region with existing infrastructure and a skilled workforce, the project could support a streamlined path from approval to production. Recent work has also highlighted the project's dual-commodity nature, with both rare earth elements and niobium relevant to sectors such as electrification, photovoltaic power generation, and advanced manufacturing.
As global competition for critical mineral supplies intensifies, St. George's strategy focuses on establishing a diversified processing and offtake network in key regions. Adding a partner with direct links to Europe's emerging magnet supply chain marks another step in this direction, potentially positioning Araxá as a multi-market supplier.
