Latest Critical Minerals News

Magnum Mining has defined a connected 32.5km² Plateau Zone at its Piracanjuba North project in Brazil after positive results from another 86 auger holes. The company is targeting a maiden JORC Mineral Resource Estimate in November 2026, but the latest desorption figures remain laboratory screening results rather than recoveries or economic data.

OD6 Metals has extended its Rocket-Big Jim-Spar fluorspar corridor at Quinn in Nevada to approximately 700 metres, with six surface samples returning at least 97% CaF₂ and three reaching 99.9%. The results expand the project’s high-grade story, but remain based on selective rock-chip sampling rather than drilling.

WhiteRock Lithium says all seven holes drilled in the first phase of its 2026 campaign intersected spodumene-bearing pegmatite, extending the Spodumene Mountain strike length by 115% to 1.4km. The result is encouraging, but laboratory assays are still needed to establish lithium grades and true widths.

Lux Copper has begun its maiden drilling campaign at the 100%-owned Baird Copper Project in Alaska, targeting historical high-grade copper results at Omar and Frost. The first assay results are expected in October, creating a near-term test of the project's exploration potential.

Nova Minerals has received approximately 500 tons of processing and refining equipment at Port MacKenzie, bringing its planned Alaska antimony facility closer to construction. The company says the delivery arrived ahead of schedule and remains targeting production in 2027.

Evion has identified a previously unmined 200m by 200m prospect at its Carp Fluorspar Project in Nevada, just 300m from the historic South Pit. Assays are pending, with geophysical surveys and a potential maiden drilling programme next in line.

Australian Critical Minerals says one extended drill hole at its Flint project in Peru has strengthened the case for a near-surface epithermal system and a deeper concealed porphyry target. The interpretation remains conceptual, with no economic-grade intersections or mineral resource reported.

Sovereign Metals says a simple add-on circuit at its Malawi project could generate US$722 million of pre-tax value from monazite by-product recovery. The opportunity is commercially striking, but remains a preliminary scoping result dependent on further testwork, approvals, funding and customer qualification.

Viridis Mining and Minerals has secured approval for a R$77.5 million BNDES financing facility, reducing the estimated senior debt still required for its Colossus rare earth project to about US$280 million. The 16-year facility carries an indicative current cost of approximately 4.8% and supports the project’s Brazilian processing and research infrastructure.

Olympio Metals has begun field exploration across its Jacknife and Raven silver projects in the United States, with drilling at Jacknife expected to start imminently. A replacement announcement also strengthens the company’s description of a historical foreign estimate, while making clear that the estimate remains non-JORC and requires fresh verification.

ActivEX has identified preliminary rare earth element anomalies across an 8km soil grid at its Aramac Project in Queensland, including 28 samples above 1,000ppm TREE. The readings come from handheld pXRF analysis and must be confirmed by laboratory assays now pending from ALS.

Osmond Resources reported a A$7.61 million FY26 loss and warned of a material uncertainty over its ability to continue as a going concern, despite holding A$5.50 million in cash. The company is betting its Spanish Orión project can move from exploration into a resource estimate and scoping study in the coming months.
