Latest Refining News

Blackpearl Group more than doubled annual recurring revenue to NZ$26.8 million in FY26, but the growth came alongside an NZ$17.8 million loss and a formal material uncertainty over its ability to continue as a going concern. The company says cost reductions, faster cash conversion and its refinanced BNZ facility can support the next phase.

Great Dirt Resources has identified 24 priority manganese targets in New South Wales and confirmed rock-chip grades of up to 51.8% manganese. The exploration progress came alongside a $19.1 million FY2026 loss, largely caused by a non-cash share-based payments expense, while cash rose to $3.81 million.

Native Mineral Resources has produced 340.9 ounces of doré in its latest Blackjack smelt, while more than 815,000 tonnes of material has been moved across two active pits. The latest bars still require assay and refinery results before their gold contribution is known.

Australian Rare Earths has moved its Koppamurra pilot plant beyond heap leaching, recovering rare earths from about 5,000 litres of leach solution into a Mixed Rare Earth Hydroxide intermediate product. The result provides an early test of the downstream flowsheet, although commercial economics and final product quality remain unproven.

Optiscan Imaging has reached an 84-case milestone in its live digital pathology study with Australian Clinical Labs, testing the InForm platform across a broad range of tissue types and disease settings. The data may support future regulatory submissions and commercial discussions, but the announcement does not disclose diagnostic accuracy metrics or regulatory approval.

Unity Metals has identified a series of demagnetised zones across more than 6km at its O’Phlay project in Cambodia, using drill-core data to refine targets for additional gold mineralisation. The company plans at least 22 holes across several prospects from early October.

Gateway Mining has identified a 3km undrilled gold target at Pewy, where geophysical features and nearby aircore results resemble the setting that preceded its Cowza discovery. First-pass drilling is scheduled for early October, backed by the company’s recently completed $45 million placement.

Gold Mountain has identified clustered niobium, magnet rare earth and phosphate anomalies across four Araxá prospects after expanding its stream sediment dataset to 515 samples. The results sharpen exploration targets, but the project remains well short of drilling, resource definition or economic assessment.

Critical Resources has completed 65 cycles across more than a month in a full-format pouch cell using its solvent-free DSD cathode matrix. The cell retained about 75% of its starting capacity, offering a useful engineering baseline but not yet a commercial performance result.

Pursuit Minerals has recorded its highest lithium brine assay at Rio Grande Sur, with a deep packer sample returning 809mg/L from the Mito tenement in Argentina. More than 20 additional samples from the completed hole remain pending, while drilling has moved to DDH-4.

Viridis Mining and Minerals has selected Sedgman and Blossom as the preferred EPCM partner for its Colossus rare earths project, with up to US$3 million approved for work before a final investment decision. The full contract remains conditional, but engineering and procurement activity will begin immediately.

Rox Resources has started surface diamond drilling at Youanmi, targeting resource conversion, incremental growth and deeper extensions of the high-grade United North system. The campaign could support future reserve growth and mine-life extensions, but its value still depends on drilling results that have yet to arrive.
