Latest Metallurgical Testwork News

QMines is spending $2.388 million on two freehold properties that remove a key access constraint over the Botos deposit near Mt Chalmers. The acquisition clears the way for modern drilling, but the deposit remains an untested conceptual opportunity rather than a defined resource.

Caravel Minerals has delayed the Caravel Copper Project’s Definitive Feasibility Study from September to the fourth quarter of 2026. The extra time will fund further metallurgical testing, groundwater modelling, environmental updates and a detailed review of the process plant capital estimate.

Magnum Mining has completed more than 10,000 metres of drilling at its Piracanjuba North rare earths project in Brazil and is shifting its main effort to the 32.5km² Plateau Zone. A further 2,000-metre diamond drilling phase will run alongside independent resource, radiological and metallurgical studies, although delayed assay turnaround creates a risk to the company’s November timetable.

Galileo Mining advanced several PGM, nickel, copper and gold targets at Norseman during FY2026, but a A$4.55 million exploration impairment pushed its annual loss to A$4.67 million. The company ended the year with A$7.48 million in cash and a growing drilling pipeline for Mission Sill and Callisto South.

Critica has produced a second high-grade mixed rare earth carbonate from its Jupiter project, closely matching the first product at 57.9% TREO. The latest laboratory result also carried higher magnet and heavy rare earth content, strengthening the case for further flowsheet development ahead of a scoping study.

Alvo Minerals has identified a high-conductance off-hole conductor and multiple untested targets at its Touro copper-zinc prospect in Brazil. An environmental licence now allows Phase 2 drilling across roughly 500 metres of previously inaccessible strike.

Global Lithium’s Manna-Nova integration study nearly doubles the project’s post-tax NPV to A$945.7 million while cutting funded pre-production capital by 59%. The plan targets first direct shipping ore in May 2027 and spodumene concentrate production by mid-2027, but still depends on funding, approvals and a final investment decision.

Tungsten Mining has produced saleable tungsten concentrate grading up to 65.9% WO3 from its Watershed project in Queensland, confirming the conventional processing route planned for its DFS. Marketing samples have now been sent to potential offtakers, although no binding agreements have been signed.

Cannindah Resources is accelerating drilling at its Cannindah Breccia deposit after identifying mineralisation beyond the existing resource and along a broader 2km structural corridor. An updated resource estimate, incorporating 45 additional drill holes and new metallurgical inputs, is targeted by the end of September.

OD6 Metals has submitted a Plan of Operations covering up to 139 drill pads and bulk sampling at its Quinn Fluorspar Project in Nevada. The application moves the project towards its first systematic drilling campaign, but approval from the U.S. Forest Service remains outstanding.

AuKing Mining has reported wide, high-grade rare earth intersections from maiden RC drilling at its Tundulu project in Malawi, including 91 metres at 1.51% TREO. The results also reveal unusually strong heavy rare earth enrichment and have prompted the company to fast-track a maiden resource estimate targeted before the end of 2026.

Ariana Resources has re-released its Dokwe drilling update after adding JORC disclosures, leaving the underlying results unchanged. The announcement reports broad gold intercepts, eight tonnes of samples sent to China for feasibility-level metallurgical testing and further work aimed at advancing the Zimbabwe project’s DFS.
