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.

Oceana Metals has more than doubled the confirmed rare earth mineralisation footprint at its Serra Negra project in Brazil to over 4.5 square kilometres. The result adds scale and several high-grade intervals, but 45 historical holes remain awaiting assays and true widths are not yet known.

AML3D has secured an initial AU$0.5 million order to manufacture three high-pressure copper-nickel components for US Navy nuclear submarines. The deal moves its Ohio operation from qualification programs into paid production, although delivery, testing and commissioning remain outstanding.

Western Gold Resources has sharply expanded the proposed Gold Duke mine, lifting its production target by 62% and forecasting A$72.9 million in operating surplus. The preliminary study is stronger on paper, but still depends on funding and the restart of toll treatment at Wiluna.

Pilbara Gold has reported strong initial drill results from the Terra Prospect at Roe Hills, including 46 metres at 3.17g/t gold and a narrower high-grade hit of 4 metres at 9.91g/t. The results extend evidence of a mineralised corridor at least 1.5km long, although substantial drilling and follow-up work remain.

Solstice Minerals has extended copper-gold mineralisation beyond Nanadie’s current resource boundary, while downhole electromagnetic surveying has identified a 140m by 140m conductor scheduled for immediate drilling. The results add momentum to a three-rig campaign, but the resource itself remains unchanged.

Prospect Resources has expanded drilling at Nyungu Central after returning a 27-metre copper intercept outside the existing resource, while maiden drilling at Sharamba confirms a new copper discovery. The results add momentum to Mumbezhi’s growth story, but most Phase 3 assays remain outstanding and no resource update has yet been made.

Vinyl Group grew FY26 revenue by 31% and nearly halved its net loss, but auditors flagged a material uncertainty over the company’s ability to continue as a going concern. The ASX-listed media group is now relying on acquisition-led growth, higher margins and possible future funding to reach profitability.

Aruma Resources has extended shallow, broad copper-silver mineralisation at its Tillex Project in Ontario, with drilling pushing the high-grade footprint 100 metres southwest and 30 metres east. Further assays are pending from a program that is only about one-third complete.

Ordell Minerals has reported broad shallow gold intersections from the first 11 holes of a 122-hole infill program at McNabs East in Western Australia. The results strengthen the case for a maiden resource in the December 2026 quarter, although most assays and the key resource work remain outstanding.

OD6 Metals has identified high-grade fluorspar at North Horseshoe Canyon in Nevada, with selective rock-chip assays reaching 60% CaF2. The results expand an interpreted 1.5-kilometre target corridor linking the Horseshoe and Big Jim areas, but drilling is still needed to establish continuity, thickness and scale.

Sentinel Metals has reported broad, stacked gold mineralisation at its Columbia project in Montana, including a 48-metre intercept at 1.13g/t gold. Fire assays have also confirmed the company’s earlier high-grade maiden-hole result, while a November resource update now looms as the key test.

PC Gold has identified a historically sampled high-grade domain at Spring Hill, with a composite 20.35m channel result grading 13.04g/t gold outside the current resource estimate. The target has not been drilled, leaving continuity and true width unresolved ahead of planned testing in late September.

Morella has established a maiden 5.44 million tonne Inferred resource at Mt Edon containing approximately 8,300 tonnes of rubidium oxide. The estimate gives the project scale, but commercial value still depends on recovery, purification and a viable product route.

Encounter Resources has reported its highest-grade niobium intersection yet at the Green Deposit, with drilling extending beyond the existing resource boundary. The result strengthens the case for further resource growth, but follow-up drilling is needed to establish continuity and true widths.

New Zealand King Salmon has raised its FY26 pro-forma EBITDA guidance to $36 million-$39 million, citing better fish performance and lower-than-expected mortality. Harvest volumes are unchanged, while higher feed and wellboat costs are expected to emerge in FY27.
