Latest Metallurgical Testing News

New Murchison Gold has added a maiden 21,000-ounce Ore Reserve at Cloudkicker while reporting a group Mineral Resource of 353,700 ounces. The update also places 150,400 ounces of underground resources beneath Crown Prince, but the reserve base remains relatively short-dated and dependent on continued drilling and operating performance.

Leeuwin Metals has confirmed gold across all 10 samples from historic tailings at its Marda Central project, averaging 0.596 g/t Au in the top metre. The result points to a potentially accessible processing opportunity, but the material remains well short of a defined resource or economic study.

Ballard Mining has lifted the Mt Ida Gold Project’s global Mineral Resource Estimate by 56% to 1.84 million ounces, led by a larger Baldock deposit and new regional resources. The increase gives the planned feasibility study a much larger technical base, although most of the resource remains Inferred and is not yet an Ore Reserve.

Global Gold Mining has reported recoveries of up to 91.4% from metallurgical tests at its Sturec gold deposit in Slovakia, providing a useful processing input for the project’s pre-feasibility study. The result is encouraging, but the weaker 79.5% recovery from transitional material and the laboratory-scale nature of the work remain important qualifications.

Basin Energy has begun preliminary leachability and XRD studies at its Newmans rare earth discovery, with follow-up drilling assays due imminently. The early-stage program adds a recoverability test to a project already showing a 3.3 km mineralised corridor in northwest Queensland.

PC Gold’s Spring Hill project emerged from FY2026 with a sharply larger resource, fresh institutional funding and a clearer path towards feasibility studies. The gold explorer remains pre-production and loss-making, but its post-year-end A$75 million raise gives it substantial room to expand drilling and development work.

Alma Metals has intersected 383.8 metres at 0.25% copper from just 10.2 metres at its Briggs project, including a higher-grade 76.7-metre zone at 0.34%. The result supports the company’s effort to upgrade parts of the resource ahead of a pre-feasibility study, although the intersection remains a downhole measurement and ended in mineralisation.

Magnum Mining has completed a 10,000-metre auger programme at its Piracanjuba North ionic adsorption clay rare earths project in Brazil, shifting its focus to a 32.5km² plateau zone. The company is targeting a maiden JORC 2012 Mineral Resource Estimate in November, but the project remains at an early exploration stage with no declared resource or reserve.

Adavale Resources has lifted its Parkes Project gold inventory to 383,300 ounces, led by a 228% increase at London-Victoria after an 85-hole drilling campaign. The company is now moving from resource definition towards metallurgical testing and a Scoping Study, although no production decision or project economics has been disclosed.

Future Metals has reshaped its Panton development plan around a potentially lower-capital Savannah processing route, but entered FY27 with only A$1.46 million in cash and a formal warning over future funding. A post-year-end A$3.56 million raising now funds the next study phase, including a larger updated resource base.

Killi Resources has intersected a 50-metre zone of visually estimated crystalline magnetite 600 metres south of Lodestone’s existing 110Mt inferred resource. The result also identified a separate 16-metre hanging-wall zone, but assays and metallurgical testing are still pending.

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.
