Estrella Resources has identified copper-bearing porphyritic diorite and gold at nine locations around Timor-Leste’s Laleno Dome, strengthening the case for a broader intrusion-related system. The geological signal is encouraging, but drilling approval and representative follow-up work remain outstanding.

Albright Metals has established a 54,200-ounce JORC 2012 Mineral Resource at the Vail Road deposit in Canada, including 22,500 ounces in the higher-confidence Indicated category. The estimate gives the company a technical foundation for a Scoping Study, but mine economics and metallurgy remain untested.

Solstice Minerals has extended the Nanadie copper-gold system to at least 1.5km of strike, with deep diamond drilling returning broad mineralisation beyond the current resource boundary. The results include a 169.3m intercept at 0.87% copper and 0.29g/t gold, while more than 40 holes remain awaiting assays.

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.

Pantoro has increased Norseman’s Mineral Resources by 2% and Ore Reserves by 9% after mining depletion, with the Mainfield delivering the clearest growth. The company also reported a $113.2 million FY2026 profit, but the next test is converting a larger geological inventory into sustained production.

West Coast Silver will begin an 18-hole diamond drilling campaign at Elizabeth Hill in October, targeting resource upgrades, western extensions and a newly defined high-grade zone. The results are intended to feed Mineral Resource Estimate updates and a scoping study in 2027.

New Talisman Gold Mines has outlined a conceptual exploration target of up to 550,000 ounces of gold beyond its existing 350,000-ounce gold-equivalent resource at the Talisman Project. The company now plans 18 to 20 drillholes in calendar Q1 2027 to test six priority mineralised structures.

Adavale Resources has expanded its Parkes gold inventory to 383,300 ounces and consolidated a 610-square-kilometre position around London-Victoria and Calarie. The gains came alongside a larger annual loss, A$4.95 million in operating cash outflows and an auditor warning that future funding remains critical.

ActivEX has eliminated its borrowings and reported a 310,000-ounce gold resource at Mt Hogan, but the balance sheet remains dependent on future funding. The ASX-listed explorer posted a $2.149 million loss after impairing exploration assets by $2.616 million.

Magnum Mining’s latest 65-hole assay batch strengthens the Plateau Zone at Piracanjuba North, where desorbable rare earth results matter more than headline grade. The company now has assays from 373 of 894 drilled holes and is targeting a maiden JORC Mineral Resource Estimate by the end of November 2026.

Lincoln Minerals has moved Minbrie’s Eagle Ridge prospect towards diamond drilling after air core work supported its geological model. But the ASX-listed explorer remains loss-making, cash-burning and dependent on further funding to continue its exploration program.

Vital Metals reported a A$16.63 million FY2026 loss after impairing its North T mine asset by A$12.73 million, while its auditor highlighted material uncertainty over the company’s ability to continue as a going concern. The balance sheet was strengthened by A$12.47 million in placements, but Tardiff’s encouraging drilling results must now translate into a larger resource and a credible pre-feasibility study.
