Latest In Situ Recovery News

Alvo Minerals has secured A$1 million from strategic and existing investors while reporting broad, near-surface dysprosium and terbium mineralisation at its Bluebush project in Brazil. The results strengthen the exploration story, but metallurgy, permeability and a maiden resource remain ahead.

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.

Brazilian Critical Minerals has signed binding agreements to acquire 90% of a Brazilian magnesium sulphate producer, aiming to secure a key input for its Ema rare earth project. The strategy offers greater supply-chain control, but the plant requires restructuring and carries estimated legacy liabilities of R$15.3 million.

Axel REE has more than doubled the Woolrich resource to 264.6 million tonnes and delivered its first Indicated classification at the Brazilian rare earths project. The upgrade comes as the loss-making explorer prepares a controlled in-situ recovery field validation program, with A$5.73 million in cash at year-end.

Cauldron Energy has expanded its defined Yanrey uranium resource to 55.6 million pounds of U3O8 after a successful exploration year, while warning that further funding will be needed to continue operations. The project remains dependent on a change to Western Australia’s uranium mining policy.

Brazilian Critical Minerals has reported striking economics for its Ema rare earths project, including a US$1.47 billion post-tax NPV, 105% IRR and six-month payback. The company’s A$7.87 million FY2026 loss, December debt maturity, permitting requirements and unresolved Drake dispute leave the development case dependent on execution and further funding.

Peninsula Energy has increased the reported uranium resource at its Lance Project in Wyoming to 59.0 million pounds, with the Ross area delivering the clearest gain. The update adds confidence around Mine Unit 4, but remains a mineral resource estimate rather than a reserve or production forecast.

Peninsula Energy expects to book an approximately US$50 million non-cash impairment against legacy assets at its Lance uranium project in Wyoming. The charge removes value from Mine Units 1, 2 and 3 as the company concentrates capital and technical resources on Mine Unit 4 and future development.

Powerhaus Uranium entered the ASX with a $2.14 million annual loss, $1.51 million operating cash outflow and net liabilities at 30 June 2026. A subsequent $9 million IPO and the Hidden Bay acquisition have given the early-stage explorer a larger exploration runway, but drilling remains subject to approvals and future funding will still matter.

Trek Metals has secured a nine-month option to acquire the 154-claim Matrix Manganese Project in Arizona for a total potential cash consideration of A$200,000. The deal offers a low-cost route into a US critical-minerals opportunity, but carries a significant related-party consideration because CEO Derek Marshall owns about 66.67% of the vendor.

Axel REE has reported a major leap in metallurgical testwork at its Caladão Project in Brazil, achieving up to 95% gallium and 74% scandium extraction from a Tiger Creek composite sample. The results mark a significant step in developing alternative gallium recovery methods beyond traditional by-product sources.

Brazilian Critical Minerals (ASX: BCM) has engaged Altris Engineering to spearhead the Front-End Engineering and Design (FEED) phase of its Ema Rare Earth Project, aiming to advance the project from feasibility towards financing and construction readiness.
