Aureka has extended the known Irvine gold system 725 metres north with two significant gold zones from its first scout hole into a previously untested conceptual target. The results support further drilling, but remain exploration intercepts rather than a new mineral resource.

Tasman Resources has received South Australian approval for its Parkinson Dam environmental programme, clearing the regulatory path for a 20-hole drilling campaign. The programme now hinges on contractor appointments and a drilling start date, with historical high-grade gold and silver results providing the geological rationale.

Lux Copper’s first three diamond holes at the Baird project in Alaska have intersected broad zones of visually identified copper mineralisation from surface and at depth. The company now faces the more consequential test: laboratory assays expected in November.

Voltaic Strategic Resources has agreed to acquire five granted Western Australian exploration licences across three gold projects for A$330,000 upfront, with up to A$2 million tied to future Rocky Ridge resource milestones. The deal broadens the explorer’s gold pipeline, but the assets remain at the target-generation stage rather than being defined resources.

Rincon Resources posted a $6.96 million FY2026 loss after writing down $5.53 million of exploration assets, while its cash balance rose following a $3.1 million placement. The explorer has narrowed its focus to Telfer South and Crackerbox, but remains dependent on future drilling and funding.

Broken Hill Gold has won tenders for two South Australian exploration licences covering 751 square kilometres, doubling its regional tenure near White Dam to more than 1,500 square kilometres. The ground includes the historically productive Manna Hill and Waukaringa goldfields, but still requires formal grant, permitting and modern drilling before its potential can be tested.

Ballymore Resources has extended high-grade silver-lead-zinc-indium mineralisation closer to surface at its Torpy’s discovery in North Queensland. The latest drilling supports a multiple-shoot interpretation, but the project remains at an early exploration stage with assays pending and no Mineral Resource defined.

Powerhaus Uranium entered the ASX with a $2.14 million annual loss, $1.51 million operating cash outflow and net liabilities at 30 June 2026. A subsequent $9 million IPO and the Hidden Bay acquisition have given the early-stage explorer a larger exploration runway, but drilling remains subject to approvals and future funding will still matter.

Minerals Exploration has intersected broad, lower-grade gold mineralisation with higher-grade structures in four holes at Jubilee South, expanding the interpreted system toward Sovereign. The company is preparing a six-hole, 1,200-metre Sovereign program, subject to approvals, while caution remains around recovery and unproven continuity.

Southern Hemisphere Mining has reported its strongest Llahuin drilling results yet, but the copper explorer ended FY26 with just $110,027 in cash and a material going-concern uncertainty. The company is relying on further funding, related-party borrowings, asset sales and a possible Chilean VAT refund to keep exploration moving.

Power Minerals has outlined a maiden conceptual Exploration Target of 9.2 million to 10.7 million tonnes at Morro do Ferro in Brazil, grading 7.8% to 9.2% TREO. The result gives the ongoing drilling program a clearer target, but 43% of the upper estimate comes from an untested projected extension and nine recent holes remain unassayed.

West Coast Silver has added a 70%-owned prospect immediately west of its Elizabeth Hill silver mine, with historical results pointing to silver, copper, nickel and palladium potential. The targets remain early-stage: the company plans data review, fieldwork and geophysics before deciding whether to drill.
