Latest Ionic Adsorption Clay News

Cazaly Resources has secured a 12-month pathway to acquire up to 90% of 64 Brazilian rare earth and uranium tenements covering 1,118km2. Early exploration has produced elevated TREO results, but the package remains at a preliminary stage and the company has yet to complete due diligence.

Alvo Minerals has expanded its Bluebush heavy rare earth project in Brazil, with new ground, encouraging clay intercepts and Florence drilling advancing toward a maiden resource. But quarter-end cash of A$227,000 covered only 0.28 quarters of reported outgoings before a subsequent A$1 million placement and option exercises.

Enova Mining has reported encouraging rare earth exploration and metallurgical results across Brazil and Australia, but ended September with just A$333,000 in cash. A proposed A$2 million placement, A$495,200 rights issue and revised 25-for-1 consolidation now sit at the centre of its next phase.

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.

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.

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.

Gold Mountain expanded its Brazilian rare earths portfolio during FY2026, taking Irajuba beyond its original conceptual target and confirming ionic adsorption clay characteristics at Capivara. The progress came alongside an $8.137 million loss, a $4.798 million impairment charge and continued reliance on equity funding.

Magnum Mining’s latest 65-hole assay batch strengthens the Plateau Zone at Piracanjuba North, where desorbable rare earth results matter more than headline grade. The company now has assays from 373 of 894 drilled holes and is targeting a maiden JORC Mineral Resource Estimate by the end of November 2026.

Gold Mountain has extended reconnaissance rare earth mineralisation at its Down Under Project in Brazil to at least 13 kilometres west of the Irajuba Exploration Target. The strongest result was 10 metres at 2,145 ppm TREO, including 2 metres at 4,607 ppm, but the data remains preliminary and metallurgical recovery is still untested.

Magnum Mining has completed a 10,000-metre auger programme at its Piracanjuba North ionic adsorption clay rare earths project in Brazil, shifting its focus to a 32.5km² plateau zone. The company is targeting a maiden JORC 2012 Mineral Resource Estimate in November, but the project remains at an early exploration stage with no declared resource or reserve.
