The Araxá Project is a de-risked project with world-class potential in Minas Gerais, Brazil, located adjacent to CBMM’s world-leading niobium mining operations. The Project was acquired by St George in February 2025.
Extensive high-grade niobium and REE mineralisation at the Araxá Project has been confirmed by past drilling. High-grade mineralisation commences from surface, with more than 500 intercepts of high-grade niobium (>1% Nb2O5) with grades up to 8% Nb2O5 plus rare earths with grades up to 33% TREO.
On 3 March 2026, St George announced a major resource upgrade with the following resource announced (see ASX Release dated 3 March 2026 ‘Major Resource Upgrade for Araxá):
Table 1: Total JORC 2012 MRE – Grade Tonnage Report using a 2% TREO cut-off.
Table 2: JORC 2012 MRE – Additional Grade Tonnage Report using a 0.2% Nb2O5 cut-off.>
The total Nb2O5 inventory associated with the Araxá Mineral Resource is 95.47Mt, comprising 70.91Mt reported in Table 1 using a 2% TREO cut-off and an additional 24.56Mt reported in Table 2 using a 0.2% Nb2O5 cut-off. The additional material in Table 2 represents blocks that meet the Nb2O5 cut-off but fall below the 2% TREO cut-off and are therefore not included in the TREO Mineral Resource reported in Table 1.
The region around the Araxá Project has a long history of commercial niobium production and provides access to infrastructure and a skilled workforce. St George has negotiated government support for expedited project approvals and has assembled a highly experienced in-country team and established relationships with key authorities in Brazil to drive the Project through exploration work and development studies.
