St George Mining Delivers High-Grade Rare Earth and Niobium Results at Araxá


 Brazil – September 2025

St George Mining Limited (ASX: SGQ) has announced exceptional drilling results from its flagship Araxá Rare Earths and Niobium Project in Minas Gerais, Brazil, marking a significant step forward in establishing the project as one of the world’s most promising critical minerals discoveries.

Outstanding Assays

The latest reverse circulation (RC) drilling confirmed exceptional rare earth and niobium grades, including:

  • 41 metres @ 4.52% TREO and 0.87% Nb₂O₅
  • 13 metres @ 7.06% TREO and 1.45% Nb₂O₅
  • 11 metres @ 7.03% TREO and 0.91% Nb₂O₅
  • 5 metres @ 11.83% TREO and 3.12% Nb₂O₅

The mineralisation starts at or near surface, hosted in soft, free-digging material, suggesting low-cost, open-pit mining potential.

Expansion Potential

Drilling has also identified a new mineralised zone, only 1 kilometre east of the current resource, with assays of 13.5 metres @ 12.34% TREO. This discovery highlights the project’s significant resource growth potential.

Metallurgical Profile

Importantly, Araxá’s rare earth mineralisation is rich in NdPr (neodymium-praseodymium) – up to 89% of TREO – and contains valuable heavy rare earths including dysprosium, terbium, gadolinium, and lutetium. Samarium is also present at ~6% of TREO, further enhancing the project’s strategic value for high-tech and clean energy applications.

Strategic Location

The Araxá project lies adjacent to CBMM’s world-class niobium operations, providing a strong infrastructure and industrial base. With Brazilian government support through the MAGBRAS program, St George is well positioned to advance the project rapidly.

Global Market Context

The niobium market is projected to grow from 79.7kt in 2025 to 99.1kt by 2030 (~4.5% CAGR). Meanwhile, the global rare earth market is forecast to expand from USD 3.95 billion in 2024 to USD 6.28 billion by 2030 (~8.6% CAGR), underscoring the importance of projects like Araxá in securing future supply.

St George Mining’s Araxá project is emerging as a major new source of critical minerals, with high grades, expansion potential, and strong geopolitical support.

Resolution Minerals Strikes Significant Gold at Horse Heaven, Idaho

Image
  Australian-listed miner Resolution Minerals (ASX: RML) has announced a breakthrough discovery at its Horse Heaven Project in Idaho, USA. The first diamond-core drill hole at the Golden Gate prospect (HH-GG25-001C) intersected a broad near-surface gold zone — 189.2 metres @ 1.30 g/t Au from a depth of just 34.1 metres. Impressively, mineralisation bottoms  out and remains open at depth. Notably, the intercept includes severa l higher-grade zones: 12.9 m @ 2.32 g/t Au from 94.4 m and 70.8 m @ 2.24 g/t Au from 128.8 m. These results suggest the presence of an intrusion-hosted gold system — a deposit style known for large tonnage potential — similar to that found at the nearby Stibnite Gold Project located only ~6 km away. The initial “Phase 1” drilling campaign comprised  10 holes totalling 2,770.6 metres, though only the first hole’s assay results have been released so far. Resolution plans to submit permits for a follow-up program of up to 50 holes to systematically test...

Platina Resources Doubles Its Laverton Footprint with Strategic Acquisition

Image
  Platina Resources (ASX: PGM)  has significantly expanded its presence in Western Australia’s Laverton Gold District by acquiring the Mt Morgans South Gold Project. The new tenement package boosts the company’s landholding to more than 312 km² , nearly doubling its exploration footprint in one of Australia’s most productive  gold belts. The Mt Morgans South  project sits close to major gold operations, including the Jupiter  and Westralia  mines, and lies within proven Archean greenstone geology known for hosting multi- million-ounce deposits . This strategic location gives Platina strong potential for new gold discoveries. The company plans to begin exploration by reviewing historical data, refining targets and preparing for future drilling programs. With this acquisition, Platina strengthens its district-scale strategy and enhances its chances  of uncovering high-value gold opportunities.
