en.Wedoany.com Reported - St George Mining has again intersected shallow, thick, and high-grade rare earth and niobium mineralization in diamond drilling at its Araxá Project in Brazil. One drill hole returned 43 metres at 8.02% TREO and 0.74% Nb₂O₅ within a broader 62.95-metre interval grading 5.80% TREO and 0.57% Nb₂O₅ from surface. This hole also included a 21-metre high-grade zone from 15 metres depth, grading 10.61% TREO and 0.67% Nb₂O₅. St George Mining has now completed 13,700 metres of drilling at the project.
Other significant intercepts from the latest 13 drill holes include: 55.2 metres at 3.47% TREO and 0.42% Nb₂O₅, 31 metres at 4.59% TREO and 0.83% Nb₂O₅, and 26 metres at 4.20% TREO and 0.80% Nb₂O₅. St George Mining Executive Chairman John Prineas said: "We are very pleased to see the latest drilling results continue to deliver very high-grade rare earths and niobium from surface. These results further confirm the large-scale mineralized body and exceptionally thick mineralized intervals."
Ongoing drilling has already increased the Araxá Mineral Resource Estimate (MRE) by 75%, lifting the total to 70.91 million tonnes at 4.06% TREO and 0.62% Nb₂O₅. Measured and Indicated category resources grew by 218% to 29.49 million tonnes at 4.56% TREO and 0.75% Nb₂O₅. The latest results, covering resource definition and infill drilling, highlight the high-grade intensity and significant mineralized thickness in the central area of the Araxá system. The mineralization is considered to contain a high proportion of magnetic rare earths.
Drilling beyond the current resource extent continues to demonstrate expansion potential. One hole, located approximately 200 metres from the existing MRE, intersected 19.35 metres at 5.65% TREO and 0.76% Nb₂O₅ from 7.75 metres depth, within a thicker 100.35-metre interval grading 1.73% TREO and 0.33% Nb₂O₅ from surface. Another infill hole intersected 138.1 metres at 2.97% TREO and 0.45% Nb₂O₅ from surface, indicating thick and consistent mineralization beyond the resource boundary. Prineas said: "It is equally exciting to see such thick, high-grade intercepts outside the existing MRE boundaries—the 100-metre intercept in infill hole AXDD107 is particularly outstanding—underscoring that we have not yet reached the limits of the mineralized system, and further expansion drilling is highly likely to deliver more resource growth."
Ongoing drilling is expected to support further resource upgrades and provide critical data for the project's feasibility study. Prineas also highlighted the similarities between Araxá and globally significant carbonatite-hosted rare earth mines, such as Mountain Pass in the USA and Mt Weld in Western Australia. He stated: "We have an outstanding opportunity to sit alongside these two global leaders in the rare earths sector. Our drilling demonstrates the continuity and scale of high-grade mineralization, providing confidence for reserve modelling in the ongoing feasibility study." Drilling at Araxá is ongoing, with a focus on resource definition within the MRE and further expansion.
