Mount Ridley Mines Limited (ASX: MRD) has declared a maiden Inferred Gallium Mineral Resource Estimate (JORC 2012) of 838.7Mt @ 29.3 ppm Ga (39.5 ppm Ga₂O₃) at a 25 ppm Ga cut-off across three blocks at the Mt Ridley Project, ~55 km NE of Esperance, WA (Figure 1). Mineralisation is shallow, flat-lying and clay/saprolite-hosted, with strong associations to HREE and scandium.

October 2025 marked a pivot for Kaiser Reef (ASX: KAU). At Henty (Tasmania), Ore Reserves rose 29% to 199 koz @ 3.28 g/t, while the plant proved ~400 ktpa—about one-third above nameplate—via low-capex debottlenecking. At Maldon–Union Hill (Victoria), shallow in-pit drilling confirmed high-grade continuity along the Eaglehawk Reef over ~160 m strike, supporting near-term underground access and platform drilling. More ounces, faster milling, clearer pipeline. Focus now: sustain

E79 Gold Mines Limited (ASX: E79) has reported a promising set of exploration results from its Laverton South Gold Project, Western Australia (Figure 1). Located approximately 130km east-northeast of Kalgoorlie, this project spans 272km² across the southern portion of the Laverton Tectonic Zone (LTZ) — one of the world’s richest gold belts.

Lion Rock Minerals Limited (ASX: LRM) has released first-pass mineralogy from the Minta Monazite & Rutile Project in central Cameroon (Figure 1), outlining broad zones of high-grade natural rutile from surface and near-surface. Results include up to 2.2% in-situ rutile and rutile making up to 71% of the heavy-mineral assemblage. With reconnaissance complete over a >5,000 km² target area and results received across ~3,800 km²

Cauldron Energy Limited (ASX: CXU) has delivered two complementary updates on the Yanrey Uranium Project in WA (Figure 1). October’s note uses fresh passive-seismic work to sharpen drill targeting at Manyingee South, Manyingee North and Koodarie ahead of near-term field activity, while September’s announcement frames a non-binding MOU with Navoiyuran that brings ISR operating expertise and potential funding pathways into the study mix.

Encounter Resources Limited (ASX: ENR) reports air-core step-outs that extend high-grade niobium more than 1 km east of the Green resource footprint at the Aileron Nb-REE Project (Figure 1), while a shallow REE corridor is emerging along the southern carbonatite margin. The program is transitioning to 200 × 80 m infill at Green East and diamond drilling for metallurgy to define resource-ready domains.

Thunderbird Resources Limited (ASX: THB) has updated its due diligence on the Springfield Gold Deposit in NSW (Figure 1), and the take-home is simple: very limited historical drilling has already cut thick, shallow gold, and the geology points to a much larger mineralised system along a 7 km structural corridor. Systematic geochem in mid-November will set up a maiden drill program immediately after assays are in.

Peninsula Energy Limited (ASX: PEN) has completed a A$69.9 million equity raise alongside full drawdown of its Davidson Kempner debt facility, settled legacy contract liabilities, and confirmed that first dried yellowcake has been produced at the Lance Central Processing Plant in Wyoming (Figure 1). The combined funding and operational milestones underpin the Horizon 2 plan and position Lance for a disciplined scale-up.

Boab Metals Limited (ASX: BML) has officially commenced Early Works at the Sorby Hills Silver-Lead-Zinc Project in WA’s East Kimberley (Figure 1)—moving from planning into on-ground activity and marking the formal start of mine development. The program covers site access roads, processing-plant foundations, non-processing infrastructure, and an on-site accommodation camp. Boab is fast-tracking pre-wet season site prep so major packages can mobilise in April 2026.

As the global energy transition accelerates, demand for base metals like copper (Cu), lead (Pb), zinc (Zn), and nickel (Ni) is booming. Yet, exploration success rates for major discoveries are shrinking worldwide. In Australia—home to an array of world-class resources—the biggest challenge isn’t finding the right rocks, it’s working out where to start looking beneath the post-mineralisation cover that hides up to 80% of the continent’s prospective geology.

Infini Resources Limited (ASX: I88) delivered three key messages in its October sequence: the discovery of visible uranium in the core at Portland Creek (Figure 1), a 68% expansion of tenure around that system, and the raising of fresh capital at a premium to accelerate drilling in Newfoundland and the Athabasca region. This summary pulls the key facts and where they fit in the bigger picture.

Cannindah Resources Limited (ASX: CAE) has outlined a near-surface Exploration Target at the Monument prospect within the Southern Porphyry Target Zone at Mt Cannindah (Qld) (Figure 1), interpreting skarn mineralisation as the upper expression of a deeper, pencil-style porphyry. The work compiles historical drilling, recent mapping, rock chips and trench/channel results into a coherent near-surface Cu-Mo model that opens new drill targets toward depth.

American Rare Earths Limited (ASX: ARR) has ticked off three important boxes at Halleck Creek Project (Figure 1): (1) impurity-removal breakthrough, (2) ~3,080 t test-mined and bulk samples dispatched for comminution, (3) third-party LREO/HREO concentrates validating the ore. The October Investor Presentation then ties the technical gains to the scale and economics of a phased development plan.

AuMEGA Metals Limited (ASX: AAM) has reported results from a surficial geochemistry (till) program at Cape Ray West, defining multiple high-grade gold-in-till anomalies along the western contact of the Isle aux Morts Granite — an intrusive body that has never been drill-tested (Figure 1). The anomalies coincide with structural breaks and magnetic features, establishing a new discovery corridor west of existing resources.

Encounter Resources Limited (ASX: ENR) has reported multiple intersections of rare earth element (REE) fluorocarbonate minerals (including bastnaesite, synchysite and parasite) from untargeted diamond drilling at the Green carbonatite, alongside a new near-surface REE hit at the Juan prospect, ~10 km from existing niobium-REE deposits in the West Arunta. The results add further evidence that Aileron hosts district-scale niobium–REE potential across several large carbonatite s
