Latest Mining Metallurgy News

PC Gold’s latest metallurgical testwork at Spring Hill reveals exceptional gold recoveries at coarse grind sizes, promising lower processing costs and higher throughput. The Pre-Feasibility Study remains on track for mid-November delivery.

Nex Metals Explorations reports metallurgical test results confirming ~1 g/t gold grades at its Kookynie Tailings Project, alongside the unexpected identification of scheelite, a tungsten mineral, as a potential byproduct.

Wildcat Resources has delivered promising early metallurgical results from its Bolt Cutter Central lithium discovery in WA’s Pilbara, showing spodumene recoveries averaging 82.5% using flotation methods from its Tabba Tabba project. Exploration drilling has extended the mineralised footprint to over 2.3km with multiple significant lithium intercepts.

Charger Metals reports strong metallurgical results from its Medcalf lithium deposit, lifting lithium and tantalum grades significantly while slashing iron content. The company’s recent 34% resource upgrade and proximity to processing infrastructure underpin plans for a scoping study.

Red Metal’s large-scale column leach tests confirm high rare earth recoveries from coarsely crushed Sybella ores using weak sulphuric acid, underpinning a low-cost heap leach development pathway.

Ark Mines has produced high-grade monazite and titanium dioxide products from its Sandy Mitchell heavy mineral concentrate, marking a key step toward commercialising its North Queensland rare earths project.

Novo Resources has delivered a maiden inferred resource estimate for the Leven Star Reef within its Belltopper Gold Project, outlining 87,000 ounces of contained gold and setting the stage for further exploration and resource expansion.

Aldoro Resources has achieved a major metallurgical milestone at its Kameelburg project, with direct acid leach tests recovering up to 72% of rare earth elements and over 99% of strontium without prior beneficiation, suggesting a potentially lower-cost development pathway.

West Cobar Metals reports promising metallurgical results from its Salazar project, highlighting a potential low-cost scandium production route via atmospheric leaching and bioleaching. The findings reinforce Salazar’s strategic value amid rising global scandium demand and ongoing U.S. critical minerals engagement.

Fulcrum Lithium’s latest metallurgical tests at Alkali Flats reveal lithium recovery rates exceeding 90% with promising low-temperature, short-duration leaching methods, expanding processing flexibility ahead of Phase 3 core analysis.

ANSTO Minerals has delivered a significant technical breakthrough in processing Korsnäs’ historical rare earth concentrate, confirming key mineral hosts and setting a clear path to optimise rare earth recovery.

Verity Resources has completed an 11,000m drilling campaign at its Monument Gold Project, confirming and extending a 154,000oz inferred gold resource with high-grade, consistent intercepts and strong metallurgical recoveries.
