St George Mining Ltd (ASX:SGQ, FRA:S0G, OTC:SGQMF) will join the S&P/ASX All Ordinaries Index from the start of trading on March 23, 2026, marking another step in the company’s rapid rise following its acquisition of the Araxá Rare Earths-Niobium Project in Brazil.
The inclusion places St George among the 500 largest companies on the ASX by market capitalisation and is expected to lift the company’s visibility among a broader pool of investors, including index-tracking funds and institutions.
St George said the index entry reflected strong market recognition of its growth into a rare earths and niobium developer of increasing global significance, with investor attention building around its 100%-owned Araxá project in Minas Gerais, Brazil.
The company acquired Araxá in February 2025 and said its market value has since risen about 20-fold to roughly $500 million as it advances plans for the project, which it describes as world-scale.
St George said inclusion in the All Ordinaries could also support improved liquidity as its shares gain exposure to a wider range of domestic and international investors.
The All Ordinaries is Australia’s oldest sharemarket index and tracks the ASX’s 500 largest listed companies by market capitalisation.
“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.
“This milestone is a credit to our highly experienced in-country team and Australian-based executives who have delivered outstanding exploration results, a large resource upgrade, strategic downstream alliances and other key steps for potential project development.
“The large resource upgrade at Araxá announced last week — which boosted total TREO tonnes to 70.91Mt and niobium tonnes to 95.47Mt — confirmed the Tier 1 status of our rare earths-niobium deposit, with high-grade mineralisation that commences from surface and is amenable to open-pit mining.
“Araxá’s favourable project logistics in Minas Gerais — a location in a region with a long history of commercial niobium production, access to existing infrastructure and availability of an experienced workforce — underline the potential for an expedited pathway to production.
“We look forward to reporting project development milestones as we continue to build shareholder wealth through the advancement of one of the world’s most exciting, near-term rare earths and niobium development opportunities.”
Substantial upgrade in MRE
Last week St George Mining reported a substantial upgrade to the Mineral Resource Estimate for its 100%-owned Araxá rare earths-niobium project in Brazil, materially increasing the scale of the deposit as the company moves ahead with development planning.
Executive chairman John Prineas told Proactive the updated resource stands at 70.91 million tonnes grading 4.06% total rare earth oxides (TREO) and 0.62% niobium pentoxide (Nb₂O₅) at a 2% TREO cut-off, marking a 75% increase on the previous estimate.
He said the resource expansion followed the success of an extensive drilling campaign completed since mid-2024.
