Latrobe Magnesium (ASX: LMG) is progressing an Australian-first pathway to produce magnesium and associated by-products from brown coal ash via a patented hydromet/thermal reduction process (Figure). In late September 2025, LMG confirmed first production of magnesium oxide (MgO) from its Hazelwood North Demonstration Plant—an operational milestone that further de-risks the flowsheet ahead of magnesium metal commissioning.

Encounter Resources Limited (ASX: ENR) has kicked off a 6-hole RC program at the Haddon copper prospect (formerly BM5) within its 100%-owned Yeneena Copper Project in the Paterson Province, ~50 km SE of Nifty, WA (Figure 1). The target sits on a major fault with coincident EM resistive response and prior aircore results that finished in gossanous, multi-element anomalism—an undercover setting analogous in style to nearby sediment-hosted copper systems and magmatic Cu-Au depos

Orange Minerals NL (ASX: OMX) has released new surface sampling results from the Lennon’s Find polymetallic project in the Pilbara, with rock chips returning standout precious and base-metal grades along a 4.5 km mineralised corridor (Figure 1). The company is moving to a single 650m diamond hole in early November to directly test a pronounced induced polarisation (IP) anomaly interpreted as a potential feeder to the known zinc-lead-silver system.

Western Yilgarn Limited (ASX: WYX) has kicked off ground-exploration planning over two gallium targets in Western Australia—Ida Holmes Junction (Figure 1) and New Norcia—building on very high-grade rock chips and historical aircore intercepts. The Company also confirms a newly granted exploration licence at New Norcia and outlines imminent on-ground reconnaissance, including helicopter follow-up over Ida Holmes Junction.

In this episode of Coffee with Samso, we continue our Exploration Discovery Series with one of the most fascinating stories to come out of Western Australia’s goldfields — the Pegasus discovery.

Andromeda Metals Limited (ASX: ADN) has advanced its High-Purity Alumina (HPA) strategy, initiating pilot-scale testwork to move its proprietary flowsheet from batch trials into continuous production— using refined kaolin feedstock from the Great White Project (Figure 1)—a key step flagged in the recent HPA Scoping Study.

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).

DevEx Resources Limited (ASX: DEV) has put a clear frame around the Murphy West story: first-pass soils are lighting up kilometre-scale, multi-element pathfinder halos across radiometric and structural targets on the southern margin of the McArthur Basin (Figure 1), echoing the Junnagunna orientation model where Pb–Cu–Be mark buried uranium.

OD6 Metals Limited (ASX: OD6) commenced Phase 2 drilling at the 100%-owned Gulf Creek Copper Project (NSW), advancing the first modern program over a historically high-grade VMS system. The campaign targets along-strike repeats of the Gulf Creek mine stratigraphy where magnetics, jaspilite exhalites, and surface pathfinders coincide (Figure 1).

DevEx Resources Limited (ASX: DEV) is leaning hard into the Northern Territory uranium thesis with a 2025 program that moves from mapping to gravity-constrained drilling across Nabarlek’s Big Radon and KP prospects (Figure 1)—two kilometre-scale radon anomalies now tied to fault architecture by new ground gravity. Heritage clearances are being finalised and the NT Government has tipped in $160k to co-fund the maiden holes, a tidy endorsement at this stage.

Yandal Resources Ltd (ASX: YRL) has confirmed a new gold discovery at the Arrakis Prospect within the Caladan target area of the Ironstone Well–Barwidgee Project — a major milestone that de-risks exploration and advances the project (Figure 1). With 54m @ 1.2g/t Au from fresh rock, including 8m @ 4.7g/t Au, the result highlights scale and continuity over more than 2.2km of strike.

AuMEGA Metals Limited (ASX: AAM) has reported a standout result from its July airborne time-domain EM survey over Cape Ray: the work both maps known mineralisation at Central Zone and—critically—defines a large, previously untested conductor just 500 m to the southeast that mirrors Central Zone’s geophysical signature. With a fully funded drilling program slated for Q4 2025, the discovery pipeline at Cape Ray continues to expand.

Terra Critical Minerals Limited (ASX: T92) has confirmed a new high-grade silver discovery at the Silent Grove Prospect within its 100%-owned Mole River Project in New South Wales (Figure 1). This update represents an important step forward in unlocking the polymetallic potential of the Mole Granite district, an area already known for tin, tungsten, and silver-rich systems.

DY6 Metals Ltd (ASX: DY6) has delivered a practical operational update across its Malawian projects (Figure 1), completing follow-up surface sampling at Tundulu and commencing a new grid-based program at Machinga. The work targets high-value mineralisation in gallium (Ga), rare earth elements (REEs), niobium (Nb) and phosphate, with assays in preparation for SGS Randfontein.

Kaiser Reef Limited (ASX: KAU) has marked its first full quarter since acquiring the Henty Gold Mine, with reconciled production reported for 1 July–30 September 2025. Alongside the steadying of Henty as the core asset, the quarter featured renewed activity at Maldon and a strategic transition at A1, setting a clearer operational footing across the portfolio.
