Ark Mines has produced high-grade monazite and titanium dioxide products from its Sandy Mitchell heavy mineral concentrate, marking a key step toward commercialising its North Queensland rare earths project.

Magnum Mining’s initial 24 auger holes at Piracanjuba North all intersected near-surface rare earth mineralisation, showing promising grades and high desorption rates that suggest efficient extraction potential under mild conditions.

Mont Royal Resources has unveiled an updated Preliminary Economic Assessment for its Ashram Rare Earths Project, confirming robust economics and a long mine life with strategic importance for Western critical minerals supply chains.

Final assays from drillhole 26LHDD073 at the Southern Porphyry target within the Llahuin Project Joint Venture validate a broad copper-gold-molybdenum mineralised system. Integration of geological and geophysical data aims to pinpoint the higher-grade core ahead of Phase II drilling.

Viking Mines reports a major metallurgical breakthrough at its Linka Tungsten Project, achieving a 62.5% WO3 concentrate at 59.8% recovery using combined gravity and flotation processing on a larger 10 kg sample, significantly improving previous results and validating a low-capex flowsheet ahead of maiden drilling.

Prodigy Gold’s scoping study for the Hyperion Gold Deposit confirms a viable open pit project with a 4-year mine life and strong financial metrics, underpinned by a 454,000-ounce resource.

Everest Metals Corporation (ASX: EMC) has upgraded its Mt Edon Critical Minerals Project resource to 4.3 million tonnes at 0.23% Rb2O, enhancing grade, tonnage, and confidence ahead of a mining proposal submission expected to gain approval by late 2026.

Critica Limited has achieved a major leap in rare earth product quality at its Jupiter Project, producing a Mixed Rare Earth Oxide with approximately 97% Total Rare Earth Oxide and strong recovery rates that bolster its mine-to-magnet ambitions.

Galileo Mining’s latest diamond drilling at Norseman reveals a newly identified ultramafic sill with 109 metres of PGM mineralisation, reinforcing the project’s potential for multiple stacked intrusive systems along extensive strike lengths.

Resolute Mining’s scoping study for its ABC Project in Côte d’Ivoire outlines a robust 12-year open pit gold operation with strong economic metrics, including a post-tax NPV of US$1.2 billion and a 39% IRR at US$3,500/oz gold.

Delta Lithium reveals a significant new fluorite discovery with assays exceeding 86% CaF2 at Yinnetharra, alongside ongoing high-grade lithium drilling and metallurgical progress at Mt Ida.

Power Minerals has kicked off a 3,800-metre diamond drilling campaign at its Morro do Ferro Rare Earths Project in Brazil, aiming to expand high-grade rare earth mineralisation and advance metallurgical studies following recent acquisition completion.
