The Splinter Rock clay-hosted REE prospect, located northeast of Esperance within the east Albany–Fraser Orogen in Western Australia, has emerged as one of the most scientifically compelling regolith-hosted REE systems in the country (Figure 1). A multidisciplinary study led by CSIRO has produced the first integrated geological, geophysical, mineralogical, and geochemical characterisation of this emerging clay-hosted REE district.

Pure Hydrogen Corporation Limited (ASX: PH2) has released two important ASX announcements outlining a step-change in its strategic positioning across Australia’s zero-emission (ZE) vehicle and clean mobility sector. The first update (29 October 2025) details a new collaboration between Pure’s subsidiary, Pure One Operations, and Advanced Manufacturing Queensland (AMQ) to begin assembling hydrogen fuel-cell trucks and the Ford F-150 Lightning locally in Brisbane.

Mount Ridley Mines Limited (ASX: MRD) has announced a significant expansion of its tenure at the Mount Ridley Gallium and Rare Earth Project, located north of Esperance, Western Australia (Figure 1). The new Exploration Licences now consolidate the entire Grass Patch Complex — a distinctive geological domain marked by gravity and magnetic highs, interpreted to be associated with mafic intrusions, and recognised as a primary source of gallium and heavy rare earth enrichment.

West Cobar Metals Limited (ASX: WC1) has released new findings from the Salazar Critical Minerals Project, located approximately 150km northeast of Esperance (Figure 1). A detailed review and re-analysis of historical drilling, paired with new RC work across Newmont, O’Connor, and adjacent prospects, has confirmed extensive gallium mineralisation throughout the system.

Proteomics International Laboratories Ltd (ASX: PIQ) has received $2.2 million in R&D tax incentive refunds for the 2024–25 financial year, reinforcing its financial position as the Company advances multiple diagnostic products towards commercialisation. Based in Perth, Western Australia, the Company continues to develop next-generation diagnostic tools built on its proprietary Promarker® technology platform, with applications across chronic disease detection, women’s health,

Lion Rock Minerals Ltd (ASX: LRM) has identified a unique “monazite-enriched granite” at the Minta Est Project in Cameroon, confirming the source of heavy rare-earth mineralisation coincident with high-grade rutile zones (Figure 1). This discovery marks a significant milestone in the Company’s exploration program across its 5,000 km² tenement, establishing Minta Est as a potential district-scale source of monazite, xenotime, zircon, and rutile.

Encounter Resources Limited (ASX: ENR) has reported a significant extension of high-grade niobium and rare earth element (REE) mineralisation at the Aileron Niobium-REE Project in the West Arunta region of Western Australia. New results from broad-spaced aircore drilling have identified a mineralised zone more than 500m east at Crean.

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.

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.

Great Northern Minerals Ltd (ASX: GNM) has announced a significant expansion of its Catalyst Ridge REE–Antimony Project in the Mountain Pass District, California (Figure 1). The move marks a step-change in the Company’s U.S. footprint, adding new ground in one of the world’s most strategic rare earth corridors.
