Latest Rare Earths News

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.

Osmond Resources has outlined a 60.0 million tonne maiden JORC resource at its Orión critical minerals project in Spain, but most of the inventory remains Inferred and unproven economically. The company will resume drilling in October, with an updated estimate targeted for the first quarter of 2027.

Cadoux says resampling of 21 historical Danube drill holes has extended rare earth-zircon mineralisation up to 1.4 kilometres north of its June Exploration Target and opened a southern target area. The results move the project towards planned infill drilling, a maiden Mineral Resource and a Scoping Study, but key mineralogy and access hurdles remain.

Ark Mines has reported a FY2026 profit after receiving Queensland-backed funding, while its Sandy Mitchell rare earths resource expanded to 379.4 million tonnes after year end. The project now has development approvals and commercial-grade testwork behind it, but no Ore Reserve or mining decision yet.

Tarrina Resources has identified five kilometre-scale IOCG target zones at Walparuta after soil sampling returned copper values up to 2,891 ppm and gold up to 466 ppb. The planned 23-hole drill campaign remains subject to native title, heritage, land access and government approvals.

Enova Mining has launched a 1-for-4 entitlement offer at A$0.001 a share to raise up to A$495,152 for exploration and working capital. The modest raising sits alongside a proposed A$2 million placement and potential Caraubas acquisition issues that could materially expand the share count.

Metallium has moved Flash Joule Heating from tiny laboratory tests to multi-reactor campaigns in Texas, backed by feedstock contracts, offtake and A$125 million raised during FY2026. Yet the ASX-listed group remains pre-revenue, lost A$42.8 million and says continued access to funding is a material uncertainty.

Core Energy Minerals has expanded into an advanced Namibian uranium joint venture, but its annual report flags a material uncertainty over continued operations. The explorer reported a $3.369 million loss, $469,346 in cash and a $1.49 million working-capital deficit for 2026.

DevEx Resources has emerged from FY2026 with a 9,200 square kilometre uranium landholding in the Northern Territory, $27.2 million in cash and a multi-target drilling campaign underway. Early alteration at KP and shallow mineralisation at Big Radon provide technical encouragement, but the exploration case remains dependent on follow-up drilling and assays.

Ausmon Resources has outlined a potential path towards maiden rare earths resource work in South Australia, but the explorer remains heavily dependent on external funding. An auditor has identified a material uncertainty over the company’s ability to continue as a going concern.

Omnia Metals has shifted its exploration focus to US antimony, silver, rare earths and gallium projects, backed by $3.1 million in equity raisings. Early Montana sampling produced follow-up targets, but the company remains loss-making and says the results are reconnaissance-scale rather than evidence of a resource.
