Latest Metallurgical Optimisation 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.

Nimy Resources has paired a maiden gallium resource and encouraging metallurgical recoveries with a sharp warning about funding pressure and an unresolved Lind legal dispute. The explorer ended FY2026 with $3.92 million in cash, but a $4.76 million Lind liability and an auditor-flagged going-concern uncertainty remain central risks.

DPM Metals has extended its Brevene Porphyry South discovery with long, high-grade gold-copper-molybdenum intercepts, including 716.6 metres at 3.30 g/t gold equivalent. Mineralisation now reaches the Chelopech mine concession and remains open in several directions and at depth.

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.

Nordic Resources is heading into a key investor conference with a 1.23Moz gold-equivalent resource base, expanding Kopsa mineralisation and a near-term resource update in prospect. The company says it has A$8.5 million in cash and no debt to fund its next drilling phase.

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.

Terrain Minerals has reported metallurgical leaching results from its Larin’s Lane Prospect showing rare-earth element recoveries up to 99% using methanesulphonic acid, alongside promising scandium and gallium extraction, setting a technical foundation for resource development.

Pivotal Metals’ latest metallurgical tests reveal copper recoveries exceeding 90% at the Horden Lake project, alongside robust recoveries of nickel, gold, silver, and palladium. These results underpin the upcoming scoping study and highlight the project’s financing potential through by-product credits.

Australian Mines is poised to kick off a key drilling campaign at its Flemington Scandium Project, aiming to expand its already impressive resource and support plans to triple scandium production amid tightening supply.

Viking Mines’ maiden drilling at Nevada’s Linka Project reveals multiple broad intervals of visually confirmed scheelite mineralisation, setting the stage for assay results that could validate a near-term tungsten supply boost.

Critica Limited has achieved a roughly 30% reduction in sulphuric acid consumption in the hydrometallurgical circuit of its Jupiter Rare Earth Project, confirmed by independent labs. This milestone complements earlier gains in concentrate grade and rare earth recovery, underpinning a lower-cost processing route ahead of the Q3 2026 scoping study.

Everest Metals has reported strong progress across its Western Australian projects, including maiden and upgraded resource estimates at Revere, Mt Edon, and Mt Dimer, alongside advancing mining and proprietary processing technology.
