St George Mining Storms into ASX All Ordinaries on Brazilian Rare Earths Boom
St George Mining has achieved a significant corporate milestone by securing inclusion in the prestigious S&P/ASX All Ordinaries (All Ords) Index, effective prior to the market opening on Monday, March 23. This move marks a major visibility boost for the company, reflecting its rapid ascent in the Australian Securities Exchange landscape.
Index Inclusion and Market Impact
The All Ords Index tracks the top 500 companies on the ASX by market capitalisation, and inclusion can significantly broaden a stock's investor audience. It enhances liquidity through greater exposure to institutional investors and index-aware funds, potentially driving further growth and stability for St George Mining.
This achievement underscores the company's remarkable rise since acquiring the Araxá rare earths and niobium project in Brazil's Minas Gerais state in 2025. Management reports that the company's market value has surged 20-fold to almost $500 million over this period, as investors increasingly recognise the scale and development potential of the Araxá project.
Araxá Project and Resource Upgrades
The Araxá project is strategically located adjacent to Companhia Brasileira de Metalurgia e Mineração's (CBMM) world-leading niobium operation on the same carbonatite body. This proximity highlights the region's strong mining credentials and infrastructure advantages, which could expedite St George's pathway to production.
In recent developments, St George has been steadily enhancing the project's technical foundations. Last week, the company reported a major mineral resource upgrade, showcasing substantial rare earth and niobium deposits. Using a two per cent total rare earth oxides (TREO) cut-off, St George disclosed a total mineral resource of 70.91 million tonnes grading 4.06 per cent TREO and 0.62 per cent niobium pentoxide.
Additionally, the company reported a combined measured and indicated resource of 29.49 million tonnes at 4.56 per cent TREO and 0.75 per cent niobium pentoxide. Notably, by applying a separate 0.2 per cent niobium pentoxide cut-off, St George has identified an extra 24.56 million tonnes of niobium-bearing material outside the two per cent TREO model, resulting in a total niobium pentoxide inventory of 95.47 million tonnes associated with the mineral resource.
Executive Insights and Future Outlook
St George Mining executive chairman John Prineas commented on the significance of this milestone, stating, "Inclusion in the All Ords index is a landmark in St George’s corporate growth and recognises the ongoing achievements at our Araxá Project and the confidence in the Company’s strategy to potentially become a globally significant rare earths and niobium producer."
Prineas further emphasised Araxá's favourable logistics in Minas Gerais, noting the region's long history of commercial niobium production, access to existing infrastructure, and an experienced workforce. These factors position the company for a potentially expedited production timeline.
With index inclusion now secured, St George is poised to leverage its elevated profile to drive further progress at the Araxá project. As a relatively small-cap company operating in the increasingly competitive critical minerals sector, with ongoing drilling activities at Araxá, the next milestones could be pivotal for investors and stakeholders to monitor closely.
