In this episode of Coffee with Samso, I speak with Oliver Frieson, the CEO and Executive Director of Guardian Metals Resources PLC, about one of the most compelling but under-discussed metals in the global supply chain — tungsten.

OD6 Metals Limited (ASX: OD6) has announced the publication of a peer-reviewed scientific paper detailing three years of advanced geological and geochemical work at the Company’s flagship Splinter Rock Rare Earth Project in Western Australia (Figure 1). The research—undertaken by CSIRO, Murdoch University, Monash University, and OD6—provides a technical, science-backed understanding of how rare earth elements (REE) occur, concentrate, and can be extracted from this large clay

Emyria Limited (ASX: EMD) has taken another step toward building a national network of intensive, evidence-based mental health services in Australia. The Company has secured funding through an $8 million institutional placement and exercised a key option with Avive Health, paving the way for its first Empax Clinic in Victoria. At the same time, insurer-funded treatments have commenced at the Brisbane Empax Clinic, adding a second reimbursed site to the existing Empax Centre i

Echo IQ Limited (ASX: EIQ) is pushing its cardiology decision-support platform into the heart failure space, with its EchoSolv HF algorithm now validated through the Mayo Clinic Platform’s independent “Validate” program in the United States. The Company, based in Sydney with operations anchored out of Western Australia, has completed what it describes as the final clinical requirement ahead of a planned FDA 510(k) submission for EchoSolv HF – a heart failure decision-support

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.

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.

Cannindah Resources Limited (ASX: CAE) has reported standout trenching results from the Southern Target Zone (Appletree–Dunno) at Mt Cannindah, Queensland (Figure 1). The work outlines a 500 m × 100 m corridor of high-order Cu-Au-Mo geochemistry coincident with IP chargeability and magnetic highs—and crucially, an untested target at the lowest topographic level within the mining leases, consistent with a preserved porphyry system.
