Latest Metallurgical Testwork News

Viking Mines has hit 14 metres at 0.56% WO3 in the first assay from maiden drilling at its Linka tungsten project in Nevada. The result confirms mineralisation below historic workings, although a duplicate sample returned a lower grade and no resource has yet been defined.

Ariana Resources has reported broad and high-grade gold intercepts from metallurgical and exploration drilling at its Dokwe project in Zimbabwe. The company has now shipped eight tonnes of samples to China for feasibility-level metallurgical testwork, while further drilling and DFS work remain ahead.

Mount Ridley Mines has told ASX it holds no unreleased exploration results that explain its share price rise, while confirming three testwork programs remain in progress. The company also disclosed that an institutional investor had approached it about participating in its current capital raising.

EV Resources has produced a 68.3% antimony concentrate from preliminary bench-scale testing of material from the Vinatas operation in Mexico. The results support Tecomatlán as a potential regional processing hub, but the proposed ore supply remains non-binding and plant-scale performance is untested.

Trek Metals has reported a second batch of shallow, high-grade manganese assays from Kuro, including 7 metres at 40.2% Mn from just 7 metres. The results bring the discovery into a larger 2,500-metre Phase 2 drilling campaign targeting geophysical anomalies across the Christmas Creek project.

Terra Metals has reported broad PGM-Cu-Ni mineralisation and repeated higher-grade reef layers from three holes at its Southwest Discovery in Western Australia. The results strengthen the geological picture ahead of a planned maiden Mineral Resource Estimate, but true widths, recoveries and resource scale remain unconfirmed.

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.

Tungsten Mining NL’s Pre-Feasibility Study confirms Mt Mulgine as a world-scale tungsten project, targeting first production in mid-2029 with robust economics and low operating costs.

Elevra Lithium's Pre-Feasibility Study for the North American Lithium (NAL) brownfield expansion in Québec outlines a staged growth plan nearly doubling spodumene concentrate production to 373 ktpa by 2029, reducing unit costs and delivering a post-tax NPV of C$3.2 billion.

Hawsons Iron has confirmed its ability to upgrade magnetite concentrate to a premium 69.3% iron grade through bulk-scale elutriation testwork, significantly reducing impurities and enhancing potential revenue streams.

Mount Ridley Mines has secured an oversubscribed $2 million placement at $0.033 per share to fast-track technical work at its Grass Patch Project and advance the Selectro™ Process. Directors plan to add $100,000 more, pending shareholder approval.

Maronan Metals has marked a transformative year with a positive Preliminary Economic Assessment, grant of a key Mineral Development Licence, and two capital raises totaling nearly A$40 million, positioning the company for accelerated development of its Queensland silver-lead and copper-gold project.
