St George Mining Ltd (ASX: SGQ) has provided an important update with respect to its 100%-owned Araxá rare earths and niobium project in Minas Gerais, Brazil – with a major upgrade to the Mineral Resource Estimate (MRE) at Araxá, reinforcing the Tier 1 status of the deposit.
Why It’s Significant
· SGQ has announced of a significant boost to the size and confidence of the Araxá Project MRE – which has increased to 111.2Mt @ 3.57% TREO, 0.70% MREO, 0.68% NdPr and 0.57% Nb₂O₅.
· Importantly, Measured & Indicated Resources have increased by 155% to 75.2Mt @ 3.64% TREO, 0.71% MREO, 0.69% NdPr and 0.58% Nb₂O₅ - and now comprise 68% of the MRE, providing a high confidence foundation for completion of economic studies and potential mine planning, which is underway in conjunction with feasibility technical adviser, Worley.
· Araxá represents the largest and highest grade hard-rock rare earths resource in South America and the world’s largest undeveloped Measured niobium resource.
· Araxá hosts a larger volume of contained NdPr tonnes in the Measured & Indicated category than each of MP Materials’ Mountain Pass and Lynas’ Mt Weld – the two largest producing rare earths mines outside China - demonstrating the strategic significance of the Araxá resource as potential near-term feedstock for rare earths refineries outside of China.
· The MRE remains open in all directions, including at depth, providing potential for further drilling to add significant volume to the resource. Importantly, 100% of the resource within the top 120m is constrained within the weathered profile – comprising mineralisation that is free-digging, supporting potential for low-cost open-pit mining.
· In terms of upside, the East Araxá discovery is not yet included in the new MRE - with five diamond rigs operating 24/7 at East Araxá to deliver a maiden resource estimate scheduled for Q4 2026.
