MRG Metals has reported exceptional rare earth grades at its newly acquired Garies project and advanced its Mozambique portfolio, but the explorer remains dependent on capital markets. The FY26 annual report flags material uncertainty over going concern despite a subsequent A$725,000 placement and a further share purchase plan.

Brazilian Rare Earths has identified a new high-grade rare earth system at Sulista South, with mineralisation traced across about 500 metres and grades reaching 13.3% TREO. Step-out and infill drilling at Sulista East has also extended the known footprint and strengthened the case for a larger year-end resource estimate.

White Cliff Minerals has expanded its Rae Copper-Silver Project into a multi-kilometre copper system, with a peak interval of 21.1% copper and recoveries reaching 95.4%. The exploration progress came alongside an A$18.8 million FY26 loss, A$14.5 million operating cash outflow and an auditor-highlighted material uncertainty over going concern.

Chalice Mining is moving Gonneville from study to execution, with a feasibility study underway and a targeted investment decision in the first half of 2028. The project’s sizeable economics sit alongside a A$26.2 million annual loss and a funding task that remains unresolved.

Iltani Resources has paired a substantial Orient silver-indium resource with $8 million in QIC backing, giving the explorer a stronger platform for its next phase of drilling and technical studies. The company remains loss-making and pre-revenue, but ended FY26 with $7.5 million in cash.

Valiant Gold’s first annual report shows a newly listed gold company with $62.8 million in cash, no debt and two Western Australian projects moving from demerger to execution. The immediate test is whether Comet can be restarted while drilling at Reedy converts resource potential into something mineable.

Oceana Metals has begun a 20,000-metre diamond drilling campaign at its Serra Negra rare earths project in Brazil, backed by high-grade historic assays and fresh capital. But the company’s $11.5 million FY2026 loss and an auditor-highlighted material uncertainty over going concern add a harder edge to the exploration story.

Ballymore Resources enters FY2027 with Dittmer moving towards underground resource drilling, bulk sampling and trial mining, while Torpy’s has emerged as a second high-grade polymetallic opportunity. The progress came alongside a $3.10 million loss, a $10.92 million royalty liability and a disclosed material uncertainty over ongoing funding.

Solara Minerals has reported a sharply wider FY2026 loss after impairing $3.14 million of exploration assets, while cash fell to $2.03 million. The early-stage explorer expanded its Bryah Basin portfolio but says further funding may be needed to continue exploration.

Power Minerals has extended confirmed high-grade rare earth mineralisation at its Morro do Ferro project in Brazil, with a new hole returning 39 metres at 4.42% TREO from 80 metres downhole. Assays from shallower and deeper sections remain pending, leaving the scale and geometry of the zone unresolved.

WhiteRock Lithium has intersected spodumene-bearing pegmatite in all 10 newly reported drill holes at its Spodumene Mountain prospect in Québec. The visual results strengthen the geological case for continuity, but assays and true widths are still pending.

PDI Gold has reported its first consolidated Mineral Resource and Ore Reserve statement since merging with Robex, lifting total resources to 10.1Moz and reserves to 4.8Moz. The headline growth came from the merger and a larger Kiniéro reserve, although Bankan’s development remains dependent on Guinea granting its exploitation permit.
