Latest Ore Reserves News

Westgold Resources has outlined a fully funded plan to lift gold production to 460-510koz by FY29 while reducing AISC to A$2,640-A$3,000/oz. The formal outlook excludes its potentially transformative Fletcher Zone, leaving a sizeable but still conceptual growth option beyond the plan.

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.

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.

Encore Minerals has approved development of the Windarra Tailings Project, triggering a $400,000 payment to Maritana Minerals and preserving the company’s exposure to future gold production through royalties. Encore will carry the project’s development and operating costs, although key execution milestones remain ahead.

EV Resources has produced a 68.3% antimony concentrate from preliminary bench-scale testing of material from the Vinatas operation in Mexico. The results support Tecomatlán as a potential regional processing hub, but the proposed ore supply remains non-binding and plant-scale performance is untested.

Barton Gold has secured approval for the environmental scope governing development studies at its Tunkillia gold and silver project in South Australia. The milestone moves the project towards a Mining Lease application, with updated resources, Ore Reserves and a pre-feasibility study targeted for the first quarter of 2027.

Cazaly Resources has extended anomalous gold mineralisation more than 400 metres south at Hastings, including a shallow 7-metre zone grading 1.2g/t. The company now plans 2,500 metres of RC drilling at Hastings and an initial test of unverified historical high-grade results at Gulls Blow.

Sun Silver has intersected silver-gold mineralisation from surface at its Maverick Silver Project in Nevada, including a higher-grade 1.5-metre zone grading 75 g/t AgEq. The results also extend the project’s antimony story and could influence future mine sequencing studies, although the shallow mineralisation remains only lightly tested.

Elevra Lithium is positioning its Québec operations for a near-doubling in spodumene concentrate capacity, while guiding to modest production growth and sharply higher capital spending in FY27. The three-stage North American Lithium expansion is targeting 373,000 tonnes per year for an estimated US$271 million.
