St George Mining Expands Araxá Rare Earths Resource to Strengthen Critical Minerals Position


 St George Mining has delivered a major milestone at its Araxá Rare Earths and Niobium Project in Brazil, reporting a substantial 75% increase in the mineral resource estimate to 70.91 million tonnes at 4.06% TREO, alongside a total niobium inventory of 95.47 million tonnes. The upgrade reinforces Araxá’s growing status as one of South America’s most significant hard-rock critical minerals projects.

The updated estimate significantly lifted the project’s measured and indicated resources, providing a much stronger foundation for future economic studies and potential development planning. With mineralisation beginning from surface and strong open-pit mining potential, Araxá is increasingly viewed as a strategically important asset in the global race to diversify rare earth supply chains beyond China.

Located in Brazil’s well-established Minas Gerais mining region, the project benefits from existing infrastructure, access to skilled labour, and proximity to world-leading niobium operations. These advantages could support faster permitting and accelerate the pathway toward production, while also improving long-term project economics.

The latest resource growth also highlights St George’s dual-commodity advantage, combining rare earths and niobium within the same carbonatite system. As demand rises for critical minerals used in EVs, wind turbines, and advanced technologies, Araxá may emerge as a high-value strategic development story for investors watching the clean energy supply chain.

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.
