Latest Rare Earths News

Magnum Mining has added 119 assay results to its Piracanjuba North database, identifying four coherent high-desorption zones across roughly 7.19 square kilometres. The results strengthen the exploration case ahead of a targeted November resource estimate, although the desorption figures remain laboratory screening results rather than process recoveries.

Arafura Rare Earths has signed a binding five-year offtake agreement covering up to 850 tonnes a year of NdPr oxide at nameplate production. The deal expands on an earlier term sheet, but leaves pricing mechanics, counterparty identity and conditions precedent undisclosed.

Critica has converted 160 million tonnes of its Jupiter rare earths resource into the higher-confidence Indicated category after infill drilling across about 10% of the deposit. The upgrade comes ahead of a scoping study that is expected shortly, although most of Jupiter remains Inferred and no Ore Reserve has been declared.

Axel REE is moving its Caladão rare earths project into the next technical test: exploratory in-situ recovery work at the Woolrich deposit. The company says bench-scale testing has recovered up to 560ppm soluble TREO, but field performance, groundwater behaviour and project economics remain unproven.

Power Minerals has extended high-grade rare earth oxide mineralisation 57 metres northwest at Brazil’s Morro do Ferro project, with drilling returning 119 metres at 4.94% TREO from surface. The result strengthens the exploration picture, but the deposit’s geometry, metallurgy and economic potential remain to be established.

Barkly Rare Earths has reported rare earth mineralisation in 43 of 44 holes at its Northern Territory project, with high-grade intervals in 30 holes. The results strengthen the case for a larger resource, but more than 300 holes and further assays are still ahead before that potential can be tested.

Lynas Rare Earths has agreed to acquire Meteoric Resources in an all-share deal valued at about A$968 million, adding the Caldeira rare earths project in Brazil to its portfolio. The proposed transaction would materially expand Lynas’ resource base, but still depends on shareholder, court and Brazilian regulatory approvals.

Barkly Rare Earths has entered its first full year as an ASX-listed explorer with A$5.38 million in cash, a 10,000-metre drilling programme underway and an early 99% magnet rare earth oxide extraction result. The technical signals are encouraging, but both the drilling data and metallurgy remain at an early stage.

American Rare Earths has expanded the proposed Cowboy State Mine in Wyoming to a 4.5 million tonne per year operation with a 26-year mine plan and an estimated after-tax NPV of US$1.07 billion. The stronger study case comes with higher capital, lower recoveries and no Ore Reserves, leaving metallurgy, permitting and funding as the next tests.

Brazilian Rare Earths has identified a new high-grade rare earth system at Sulista South, with mineralisation traced across about 500 metres and grades reaching 13.3% TREO. Step-out and infill drilling at Sulista East has also extended the known footprint and strengthened the case for a larger year-end resource estimate.

Power Minerals has extended confirmed high-grade rare earth mineralisation at its Morro do Ferro project in Brazil, with a new hole returning 39 metres at 4.42% TREO from 80 metres downhole. Assays from shallower and deeper sections remain pending, leaving the scale and geometry of the zone unresolved.

Basin Energy has more than doubled the mineralised footprint of its Newmans rare earth discovery to 6.7km, with follow-up drilling also producing the strongest magnet rare earth interval reported so far. The early-stage results set up a busy fourth quarter of leach testing and further drilling, although no resource or recovery result has yet been established.
