St George Mining’s Araxá Project — High-Grade Niobium & Rare Earths


 

According to Colitco (September 3, 2025), St George Mining (ASX: SGQ) announced outstanding drilling results from the Araxá Project in Minas Gerais, Brazil:

  • Exceptional grades recorded from reverse circulation (RC) drilling, with some highlights:
    • 41 m at 4.52 % TREO and 0.87 % Nb₂O₅
    • 13 m at 7.06 % TREO and 1.45 % Nb₂O₅
    • 11 m at 7.03 % TREO and 0.91 % Nb₂O₅
    • 5 m at 11.83 % TREO and 3.12 % Nb₂O₅
  • These mineralized zones begin at surface and are hosted in easily excavated materials, suggesting potential for low-cost, open-pit mining. A newly discovered extension—just 1 km east of the existing resource—yielded assays of 13.5 m at 12.34 % TREO, indicating significant resource upside.
  • The deposit includes high-value elements, especially NdPr (neodymium-praseodymium) grades of up to 89 % of TREO and elevated amounts of heavy REEs (dysprosium, terbium, gadolinium, lutetium), plus samarium at ~6 % of TREO—making the metallurgical profile particularly compelling.
  • Strategically, Araxá is adjacent to CBMM’s major niobium operations and enjoys strong governmental support—including through Brazil’s MAGBRAS initiative—positioning it as a standout project in global REE and niobium supply chains.
  • Market context: The global niobium market is projected to grow from ~79.7 kt in 2025 to ~99.1 kt by 2030 (~4.5 % CAGR), while the global rare earth market is expected to expand from USD 3.95 billion in 2024 to USD 6.28 billion by 2030 (~8.6 % CAGR).

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.
