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

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.

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.

Invion Limited (ASX: IVX) has signed a funded collaboration with Protect Animal Health Inc. (Taiwan, 7850.TT) to evaluate Photosoft™ in veterinary oncology across in-vitro, in-vivo, and companion-animal studies. Invion supplies compounds, Protect funds, and runs the work. Invion retains all Photosoft IP, with scope to move to a co-development/commercial agreement if results warrant.

icetana Limited (ASX: ICE) has landed its largest Australian sale to date—a five-year SaaS order via Millennium Services Group, a national security and cleaning operator in which SoftBank Robotics holds a controlling stake.

Proteomics International (ASX: PIQ) has expanded its research agreement with the University of Melbourne and the Royal Women’s Hospital (RWH), a leading centre for endometriosis research. The partnership has two clear streams: (1) additional clinical validation for Promarker®Endo—PIQ’s first-in-class blood test for diagnosing endometriosis—and (2) discovery work toward a tissue-specific, next-generation test using peritoneal fluid to improve disease localisation.

Rumble Resources Limited (ASX: RTR) has kicked off a ~20,000 m diamond program at Western Queen (Figure 1), with two DDH1 rigs chasing high-grade down-plunge gold beneath the South and Central pits while advancing sub-parallel tungsten lodes. The work targets growth/upgrade of the 370 koz @ 3.1 g/t Au MRE and builds on the 13.2 kt WO₃ tungsten MRE, supported by geotech and metallurgy (+93% historical Au recovery).
