Latest Metallurgical Testwork News

Critica Limited has achieved a significant breakthrough at its Jupiter Rare Earth Project, lifting magnet rare earth recovery to approximately 81% and total rare earth oxide recovery to around 71% through pilot plant optimisation. This advance strengthens the foundation for its ongoing scoping study and downstream processing plans.

Viking Mines has launched a field campaign at its Linka Tungsten Project targeting historical tailings and ore stockpiles as potential near-term, low-capital feed sources, complementing ongoing metallurgical advances and a planned June quarter drilling campaign amid record tungsten prices.

Marmota Limited is set to embark on a substantial drilling campaign targeting the southern Mainwood extension of its Greenewood gold discovery in South Australia's Gawler Craton, aiming to expand the mineralised strike to 2km.

Southern Hemisphere Mining and partner FMR Resources have reported broad gold-copper-molybdenum mineralisation at the Southern Porphyry target in Chile, confirming a large porphyry system. Despite fertile intrusive phases intersected, the mineralised core remains elusive, setting the stage for targeted Phase II drilling.

Solstice Minerals has successfully closed a $32.6 million placement and raised an additional $0.81 million through option exercises, issuing nearly 35 million new shares now available for immediate trading.

Flynn Gold Limited (ASX: FG1) is intensifying exploration at its Golden Ridge Project in northeast Tasmania, focusing on trenching and drilling to extend high-grade gold mineralisation. Concurrently, the company is assessing the feasibility of a regional gold processing hub and progressing exploration at the Mangana Project with government support.

Aurum Resources Limited has reported a 34% increase in the Mineral Resource Estimate at its Napié Gold Project in Côte d'Ivoire, raising the total resource to 1.16 million ounces of gold. This growth lifts Aurum’s combined group gold resources to 4.2 million ounces across its Côte d'Ivoire assets, supported by ongoing drilling and strong metallurgical recoveries.

West Cobar Metals (ASX: WC1) is progressing its U.S.-focused critical minerals strategy by formally engaging with U.S. government funding programs and partnering with Washington D.C.-based advisor GreenMet. The company’s Australian projects contain key minerals aligned with U.S. supply chain priorities, while it evaluates potential U.S. acquisitions to expand its footprint.

Viking Mines Limited has reported successful results from an expanded ground gravity survey at its Linka Tungsten Project in Nevada, identifying numerous new high gravity anomalies that correlate with known mineralisation and concealed targets beneath volcanic cover. These findings support the company’s plan to commence drilling in the June quarter.

Locksley Resources has initiated a four-hole diamond drilling program at its El Campo Rare Earth Element Prospect within the Mojave Project, aiming to test high-grade mineralisation continuity near a major US REE mine.

OD6 Metals has announced continuous and high-grade fluorspar mineralisation at its Quinn Fluorspar Project in Nevada, with channel sampling returning 12 metres at an average grade of 40.8% CaF2, including a peak of 54.0% CaF2. These results validate historic data and indicate a large-scale breccia replacement system with significant untested potential.

Kingsland Minerals has announced breakthrough metallurgical test results from its Leliyn Graphite Project, revealing gallium recoveries up to 94%. The critical metal’s extraction potential could enhance project economics, with plans to establish a maiden gallium JORC Resource in 2026.
