Latest Heavy Rare Earths News

Core Energy Minerals (ASX:CR3) has reinforced the prospectivity of its Tunas Rare Earth Element Project in Brazil with new assay results confirming thick, near-surface mineralisation and elevated yttrium levels, while mineralisation remains open at depth.

Basin Energy's maiden drilling at Newmans Prospect outlines a 3.3 km corridor of magnet rare earth mineralisation, validating a preserved-weathering exploration model and identifying two priority target zones for follow-up.

Astron Limited is advancing talks for a $220 million senior debt package to fund Phase 1 of its Donald Rare Earths and Mineral Sands Project, with a final investment decision now expected in Q3 2026.

Axel REE has confirmed that its Woolrich deposit in Brazil is amenable to in situ recovery (ISR) using a mild magnesium sulphate solution, recovering high-grade rare earths with low impurities. This breakthrough supports the design of field-scale ISR tests planned for late 2026.

Red Metal’s large-scale column leach tests confirm high rare earth recoveries from coarsely crushed Sybella ores using weak sulphuric acid, underpinning a low-cost heap leach development pathway.

ABx Group has confirmed its second mixed rare earth carbonate sample from Tasmania’s Deep Leads deposit exhibits even lower radioactivity than the first, reinforcing its exemption from radiological control and attracting positive feedback from key customers.

Victory Metals has achieved a major processing milestone at its North Stanmore Project, producing a 7.1% Total Rare Earth Oxide concentrate with 40% heavy rare earth oxides through continuous flotation at pilot scale.

Dateline Resources has pinpointed three priority zones for heavy rare earth exploration at its Music Valley project in California, following a detailed helicopter-borne geophysical survey that revealed structurally complex areas with elevated thorium signatures.

Iondrive Limited’s proprietary IONSolv™ process has independently achieved a 93.5% recovery rate for dysprosium from US commercial e-waste, vastly outperforming previous techno-economic assumptions and extending its rare earth extraction capabilities into heavy rare earths.

IperionX has acquired Covia’s Camden mineral assets adjacent to its Titan Project, consolidating a key U.S. critical minerals province and enhancing its supply chain for heavy rare earths and titanium.

Energy Transition Minerals (ASX: ETM) has identified ten new rare earth mineralised zones at Kvanefjeld, including a significant 1.8km trend with uranium levels below Greenland’s legal threshold, but faces regulatory uncertainty as licence renewal is recommended for denial.

St George Mining’s initial beneficiation testwork at its Araxá Project in Brazil has delivered high-grade niobium concentrates and a promising rare earth concentrate, validating its dual commodity approach and underpinning next-stage pilot plant plans.
