Latest Reserves News

Catalyst Metals has lifted the Keillor gold Resource from 81koz to 307koz after a major drilling campaign, while the operating mine ramps up near the Plutonic processing plant. The company expects an Ore Reserve update to extend Keillor’s initial three-year mine life.

Sovereign Metals says a simple add-on circuit at its Malawi project could generate US$722 million of pre-tax value from monazite by-product recovery. The opportunity is commercially striking, but remains a preliminary scoping result dependent on further testwork, approvals, funding and customer qualification.

Rox Resources has increased Youanmi’s Ore Reserve by 8% to 727,000 ounces after mining depletion, while the broader Mineral Resource edged up to 2.195 million ounces. The update excludes results from recent surface and underground drilling programs, leaving future revisions as a potential source of change.

Olympio Metals has begun field exploration across its Jacknife and Raven silver projects in the United States, with drilling at Jacknife expected to start imminently. A replacement announcement also strengthens the company’s description of a historical foreign estimate, while making clear that the estimate remains non-JORC and requires fresh verification.

Metal Hawk has highlighted a shallow, high-grade gold intercept at the Numbat lode in Western Australia, with the structure remaining open along strike and at depth. Follow-up drilling is due to resume shortly, but the discovery remains an exploration result rather than a defined resource.

Equus Energy has completed Pre-FEED on its large North West Shelf gas project and signed a conditional 10-year gas sales agreement with Alcoa. But the annual report also shows a $25 million loss, a $12 million rehabilitation provision and substantial funding and permitting hurdles before development can begin.

Bass Oil has set out a growth plan spanning Indonesian oil production, a planned Vanessa gas restart and development of its Kiwi discovery in South Australia. The strategy offers several potential catalysts, but much of the upside remains dependent on funding, approvals and execution.

Polymetals Resources moved its Endeavor silver-zinc-lead mine from restart to commercial production in FY2026, generating A$100.0 million in revenue. The milestone came alongside a A$47.0 million loss, negative operating cash flow and an auditor warning over going-concern uncertainty.

Osmond Resources reported a A$7.61 million FY26 loss and warned of a material uncertainty over its ability to continue as a going concern, despite holding A$5.50 million in cash. The company is betting its Spanish Orión project can move from exploration into a resource estimate and scoping study in the coming months.

Argosy Minerals has opened a share purchase plan targeting up to $0.5 million at $0.036 a share, matching its recently completed placement price. Participating shareholders will receive one free unlisted option for every two shares, but the non-underwritten offer adds another layer of potential dilution.

Ballymore Resources has reported its strongest Torpy’s intersection yet, with shallow drilling returning 580.4g/t silver, 25.88% lead, 10.08% zinc and 8.7g/t indium over 2 metres. The result extends mineralisation 40 metres up-dip and supports the company’s emerging high-grade shoot model, although the project remains at the exploration stage.

Astral Resources has reported a 1.54g/t Au weighted average across 41 infill holes at Theia, including several high-grade intervals that exceed the existing Stage 1 resource grade. A separate deviated hole returned 1m at 219g/t Au, adding further support to the early mining inventory while deeper drilling continues.
