Latest Resource Estimates News

Athena Resources has expanded its Byro Magnetite Project resource to 76.3 million tonnes and begun drilling at Narryer, the prospect earmarked for potential early development. The progress came with a $1.11 million FY2026 loss, a non-binding joint venture and fresh funding still supporting an exploration-stage business.

Tarrina Resources has identified five kilometre-scale IOCG target zones at Walparuta after soil sampling returned copper values up to 2,891 ppm and gold up to 466 ppb. The planned 23-hole drill campaign remains subject to native title, heritage, land access and government approvals.

New Murchison Gold has reported high-grade drilling across three Lydia deposits near its Crown Prince operation, led by a 1m interval at 47.20g/t gold. The results define shallow mineralised zones, but remain outside the current Lydia resource and still require further drilling and modelling.

Gullewa’s full-year profit fell sharply despite a $2.98 million royalty stream from the Deflector Project. The company is expanding its property and gold exposure while maintaining a fully franked dividend of 0.7 cents per share.

PolarX Limited (ASX:PXX) has reported a year of high-grade exploration results across Alaska and Nevada, led by a 24.8-metre copper intercept grading 9.8% at Caribou Dome. The company ended FY2026 with A$10.0 million in cash, but remains loss-making and dependent on future funding and exploration success.

Norwest Minerals has strengthened the technical case for its Bulgera heap-leach project with a revised 191,000-ounce resource and 86% bottle-roll recoveries. But the ASX-listed explorer ended FY2026 with $394,541 in cash, and its auditor highlighted material uncertainty over its ability to continue as a going concern.

Latitude 66 returned to a A$1.71 million FY2026 profit as asset sales funded a larger gold resource base and major KSB milestones. But the auditor flagged material uncertainty over the explorer’s ability to continue without further funding.

Ausmon Resources has outlined a potential path towards maiden rare earths resource work in South Australia, but the explorer remains heavily dependent on external funding. An auditor has identified a material uncertainty over the company’s ability to continue as a going concern.

Altamin has completed the core technical work for its Lazio geothermal brine Scoping Study, but auditors have flagged material uncertainty over the company’s ability to continue as a going concern. The ASX-listed developer ended FY2026 with A$2.39 million in cash after raising A$5.39 million during the year.

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.

St George Mining’s Araxá project now boasts a 111.2Mt rare earths resource after a major post-year-end upgrade, alongside 630,000 tonnes of contained niobium. The 2026 annual report shows a company moving rapidly towards development, but still without an ore reserve, mine design or production decision.

Eminence Minerals has cut its FY2026 loss and raised its pro forma cash position to about A$5.4 million after selling the Mata da Corda titanium project. The portfolio is now centred on Hamersley iron ore and Brazilian rare earth exploration, but heritage litigation, ungranted tenure and future funding needs remain material constraints.
