Western Yilgarn expanded its inferred bauxite inventory to 244Mt and added gallium, tellurium, cobalt, scandium and gold targets during FY2026. But the explorer ended the year with $159,481 in cash, a $1.78 million loss and an auditor warning that further funding is required to continue planned activities.

Critica has produced high-purity mixed rare earth oxide and iron concentrate samples from its Jupiter project, giving potential counterparties physical products to evaluate. The milestone follows flowsheet improvements including stronger recovery, higher concentrate grades and lower sulphuric acid consumption, but commercial specifications and project economics remain unresolved.

Historical work has identified widespread near-surface columbo-tantalite mineralisation at Australasian Metals’ Atex project in Côte d’Ivoire, adding a potential tantalum stream to its lithium strategy. The results are encouraging, but the underlying estimate is non-JORC, unverified and based on incomplete historical records.

Fortuna Metals has reported a sharply expanded exploration base at its Mkanda rutile and graphite project in Malawi, alongside a narrower FY2026 loss and A$8.6 million of post-year-end funding. The resource remains early-stage and inferred, but the scale and product quality have moved the project into a more consequential development phase.

OD6 Metals has transformed its portfolio with the completed acquisition of Nevada’s Quinn Fluorspar Project, but the strategic expansion comes alongside a larger loss, ongoing funding needs and substantial permitting risk. The company is now targeting drilling and a maiden resource at Quinn while advancing laboratory-scale rare earth processing work at Splinter Rock.

Gibb River Diamonds reported a A$5.61 million profit after receiving a A$7 million pre-GST distribution from its Neta gold joint venture. The cash windfall leaves the explorer with A$6.74 million in the bank, but its next challenge is converting a one-off mining payment into a credible development pipeline.

Bellavista Resources is advancing a 15,000-metre drilling campaign and early development studies at Pickle Crow, while assay results have been pushed into October after Canadian laboratory delays. At Brumby, continuity drilling is complete and CSIRO column leach testwork is being prepared.

Viking Mines has identified several wide zones of visually confirmed scheelite in ongoing RC drilling at its Linka tungsten project in Nevada, including 22 metres across a 24-metre horizon. The encouraging visual results remain unassayed, leaving laboratory results as the next critical test of grade and continuity.

Mount Ridley Mines says its third Selectro™ leach test lifted scandium recovery to 91.8% while using roughly half the reagent dose of earlier tests. Heavy and light rare earth recoveries also improved, although gallium recovery fell sharply.

Tungsten Mining has produced saleable tungsten concentrate grading up to 65.9% WO3 from its Watershed project in Queensland, confirming the conventional processing route planned for its DFS. Marketing samples have now been sent to potential offtakers, although no binding agreements have been signed.

MRG Metals says grid hand-auger drilling has outlined a visually mineralised 1.6 square kilometre footprint at its Adriano rare earths project in Mozambique. The result expands the exploration picture, but laboratory assays are still pending and no Mineral Resource has yet been established.

OD6 Metals has submitted a Plan of Operations covering up to 139 drill pads and bulk sampling at its Quinn Fluorspar Project in Nevada. The application moves the project towards its first systematic drilling campaign, but approval from the U.S. Forest Service remains outstanding.
