St George Mining Limited is developing the world-class rare earths-niobium Araxá Project in Minas Gerais, Brazil.
The Project has the largest high-grade carbonatite-hosted rare earths deposit in South America and one of the highest resources for magnet rare earths in the world.
In addition, the Araxá Project has one of the world's largest undeveloped niobium deposits – a metal which is added to iron to create high-strength low-alloy (HSLA) steel. Niobium is rated the second most important critical metal by the US with 90% of global production from Brazil.
On 11 August 2026, St George announced an upgrade to the Mineral Resources Estimate (MRE) for the Project as shown below:
Total JORC 2012 MRE – Grade Tonnage Report using a 2% TREO cut-off.

Contained metal now comprises 3.98Mt of TREO – including 760,000t of NdPr oxides – as well as 630,000t of Nb2O5 – highlighting the Project's unique world-class rare earths and niobium inventory.
The higher-confidence Measured & Indicated categories now represent approximately 68% of the total MRE and contain approximately 520,000t of NdPr oxides and 440,000t of Nb2O5–providing a strong foundation for metallurgical testwork, pilot plant programs, mine planning and economic studies for a potential long-life mining operation.
The region around the Araxá Project has a long history of commercial niobium production and provides access to existing infrastructure and a skilled workforce. The high-grade mineralisation at the Project starts from surface which, together with the favourable project logistics, provides St George with a fast-track to production.
St George has negotiated government support for expedited project approvals and assembled a highly experienced in-country to drive the Project through development studies and into production.
St George is forging downstream partnerships with end-users in Europe and the US with the aim of supporting critical minerals supply chain outside of China.
