A continent-scale hyperspectral map produced by CSIRO uses satellite data across more than 200 narrow spectral bands to characterise surface mineralogy across Australia. The dataset resolves subtle spectral signatures of alteration minerals and regolith units, giving explorers a uniform, wall-to-wall baseline that can be integrated with geophysics, drilling and geochemistry for greenfields targeting. For geologists and resource modellers, the map offers rapid screening of prospective terrains, improved lithological mapping in covered areas, and a consistent framework for regional mineral systems analysis.

Wildfires could damage or destroy between 133,000 and 449,000 structures across the US from 2024 to 2060 if current development patterns and limited adaptation persist, according to a new peer‑reviewed risk assessment. The projected losses nearly triple current estimates, driven by continued expansion of housing into the wildland–urban interface and inadequate fire‑resilient design. For civil and geotechnical engineers, this signals rising demand for fire‑hardening of infrastructure, updated land‑use planning, and performance‑based codes for foundations, retaining systems and utilities in high‑risk corridors.

Researchers at the University of Hertfordshire are launching a detailed investigation into the façade “chimney effect” that allowed flames and smoke to race up Grenfell Tower’s cladding system in 2017. The work will focus on how ventilated cavity geometry, insulation and cladding panel configuration influenced vertical fire spread and smoke movement. Findings are expected to inform future façade fire engineering, including cavity barrier design, material selection and test methods for high-rise residential towers.

One World Lithium has delivered Moleaer industrial nanobubble generators to laboratories at the University of California, Irvine and the University of British Columbia to advance its single-step direct lithium carbonation extraction (DLCE) process. The collaboration aims to move from bench-scale to a mobile, containerised pilot plant at Moleaer’s Los Angeles facilities by early 2027, using CO₂ nanobubble extraction on natural brines to produce direct lithium carbonate and co-produce sodium, calcium, magnesium and potassium carbonates. Phase 2 lab work will test lithium-bearing clays, targeting acid-free extraction without sulphuric acid, soda ash, sorbents or multi-stage concentration.

UK Research and Innovation has commissioned a £20M national trial, led by Arup with the Carbon Trust, Ipsos and Technopolis, to test whether households and businesses can be shifted to use more electricity during periods of high wind and solar output. The programme will explore time‑of‑use incentives, smart meter data and automated controls to move flexible loads such as EV charging and heat pumps into surplus‑renewables windows. Results will inform future grid reinforcement needs, demand‑side response design and network planning assumptions for distribution operators.

Successive summer heatwaves caused more than 50,000 heat-related excess deaths across 854 European urban areas, according to joint modelling by Imperial College London and the London School of Hygiene & Tropical Medicine. The analysis links mortality spikes to prolonged high night-time temperatures and dense urban morphology, where limited green infrastructure and high building thermal mass trap heat. For civil and infrastructure engineers, the findings strengthen the case for city-scale cooling strategies such as reflective pavements, shaded public realms and revised design criteria for heatwave return periods.

Buried reservoir sediments at Les Guilleteres d’All in Catalonia’s Cerdanya Valley show Roman miners used a hydraulic network to wash gold-bearing alluvium in the eastern Pyrenees between the 2nd and 4th centuries CE. Optically stimulated luminescence dating of infill from a 4.5 m-wide, 1.5 m-deep stone‑dammed reservoir indicates the system post-dates active use, while landscape evidence points to roughly 2 million m³ of material reworked into ravines, trenches and a 300 m-wide excavation front. The work confirms large-scale Roman hydraulic mining beyond Las Médulas and links activity to the nearby settlement of Iulia Libica (modern Llívia).

Royal Engineers have trialled low-resource concrete mixes using crushed recycled brick as aggregate, salt water as mix water and on-site 3D printing to build structures in conflict and disaster zones where fresh water and conventional materials are scarce. The work focuses on rapidly deployable field production, aiming to print blast walls, shelters and foundations without fixed batching plants or potable water supplies. For civil and military engineers, the approach raises design questions around chloride-induced reinforcement corrosion, variable brick aggregate grading and verifying strength without standard laboratory testing.

Vulcan Elements has partnered with the North Carolina Collaboratory and UNC-Chapel Hill chemist Yosuke Kanai to use quantum-mechanical simulations to predict how atomic-level changes affect rare earth magnet properties, backed by a $600,000 research award. The work feeds directly into Vulcan’s 1.1 million-square-foot Benson, North Carolina plant, designed for 10,000 t/y of magnet production and billed as the largest rare earth magnet factory outside China. Vulcan claims its material, technology, software, IP and ownership are fully decoupled from Chinese supply chains, aligning with its existing $1.4 billion US government-backed partnership with ReElement Technologies.

A new Systemic and ERM scenario report for ICMM, funded by the Gordon and Betty Moore Foundation, models three pathways for mining and metals to 2050, with copper demand varying by up to 30% and major swings in water use, mine count and deforestation. The “Flywheel” scenario assumes globally connected supply chains, streamlined permitting and verified low‑impact operations, yielding 18% higher copper demand with 35% lower water consumption, 18% fewer mines and 25% less deforestation. In contrast, a fragmented “Fracture” world drives 70% higher water use, 25% more mines and 40% more deforestation, while a “Space Race” tech‑driven bloc system keeps copper demand high but trims deforestation by 3%.

USGS experiments on 57 hydrothermal rock samples from the Escanaba Trough off the Oregon–California border found that two metal‑rich seafloor massive sulphide specimens spontaneously ignited during freeze‑drying and crushing, reaching temperatures above 100°C and fully oxidising. Detailed mineralogical work traced the exothermic behaviour to nanocrystalline marcasite, an unstable iron sulphide phase, implying that oxygen exposure and mechanical grinding on ships could trigger rapid fires in stockpiled deep‑sea ore. Prospective operators may need pre‑extraction mineral stability screening and new protocols for handling, storing and ventilating crushed sulphide material aboard vessels.

General Fusion’s Lawson Machine 26 (LM26) experiment has achieved electron temperatures above 12M°C in a large-scale magnetised target fusion set‑up, with measurements co‑authored and independently verified by the UK Atomic Energy Authority (UKAEA). The LM26 platform is designed to validate plasma heating and confinement physics at reactor‑relevant scale ahead of General Fusion’s planned commercial demonstration plant at the UKAEA Culham Campus. For infrastructure planners, the result signals progress towards grid‑scale fusion facilities that will demand high‑integrity civil structures, advanced shielding and complex thermal management systems.

Larvotto Resources has reported high-grade gold–antimony–tungsten intercepts from four lodes at the Metz Mining Centre within its Hillgrove project in New South Wales, including a newly identified lode named Echidna. Key results include 20.5m at 9.4g/t gold equivalent (AuEq) from 342.5m at Blacklode, with a higher-grade core of 6.2m at 27.2g/t AuEq from the same depth. The grades and depths point to underground mining potential and support further resource definition drilling targeting multi-commodity sulphide mineralisation.

Women hold only 12% of CEO and head-of-business roles in Australian mining despite making up 23% of the workforce, with representation dropping from 24% in management and 25% in senior management to the top tier, according to BCEC and WGEA’s Gender Equity Insights 2026 report. The study of 8,239 employers shows women in mining move into management at 0.7% versus 0.5% for men and enjoy a 2.3-point promotion advantage, yet mining remains a major contributor to the national remuneration gap, adding an estimated A$3,825 to the total pay disparity. Researchers link higher female board representation and appointing female CEOs with stronger ASX company performance—around A$119 million extra market value at median asset size—while warning that limited part-time senior roles (13.2% of employers) and weak support for shared caring responsibilities risk constraining the leadership pipeline in technical and operational streams.

South America’s Lithium Triangle holds about 64 million tonnes of identified lithium resources (43% of the global 150 million tonnes), yet geologist José Cabello’s review of 43 salt flats across Argentina, Bolivia and Chile shows that variable brine chemistry, impurities and groundwater behaviour make recovery and costs highly site-specific. Salar de Atacama benefits from ultra‑dry climate, relatively clean brines and strong logistics, while other basins such as Altoandinos, Pedernales, Hombre Muerto Oeste, Rincón, Sal de los Ángeles and Sal de Vida face tighter water and hydrogeological constraints. Direct lithium extraction (DLE) could unlock lower‑grade or impurity‑rich brines, but Cabello stresses that trade‑offs between brine withdrawal and freshwater consumption mean technology selection must be tailored to each basin’s hydrology and ecosystem.

UK researchers led by the University of Birmingham have secured £6.2 million from the UK’s Advanced Research and Invention Agency to develop protein-based membranes that can selectively separate lithium from sodium for high-purity battery-grade compounds. The three-year project will engineer S‑layer proteins into large-area membranes with uniform, programmable pores, combining AI-guided protein design by Fold9, membrane scale-up and testing by Evove, and high-throughput variant screening by Adaptyv Bio. Success would provide lithium producers with a new DLE route, contingent on achieving industrial-scale durability and consistent separation performance outside the lab.

A University of Cambridge research team has developed a data-driven framework to measure construction productivity consistently across projects by converting routine project records into actionable performance metrics. The methodology standardises inputs such as programme data, labour hours and cost codes, then links them to outputs like installed quantities and rework volumes to generate comparable productivity indicators. For contractors and clients, this enables benchmarking across sites, early detection of underperforming work packages, and more evidence-based decisions on methods, sequencing and resource allocation.

Global rare earth element supply remains constrained not by crustal scarcity but by discoverability, complex mineralogy and marginal economics, with lanthanides like cerium more abundant than copper yet commercially viable ores largely limited to bastnäsite, monazite and xenotime. Exploration relies on proxy signatures rather than direct REE detection, combining magnetics, gravity, radiometrics, IP, MT, seismic reflection, ERT/EM and hyperspectral imaging (from EnMAP/PRISMA satellites to core scanning) to target carbonatites, alkaline intrusions, unconformity systems and ion-adsorption clays. Metallurgical risk is high: refractory hosts (eudialyte, zircon), radioactivity from thorium/uranium, and the need to confirm genuinely ionic IACDs via costly lab tests leave many anomalies uneconomic, reinforcing China’s dominance, particularly in heavy REEs from southern China and Myanmar.

Deep cave mining faces an acute skills crunch as Deloitte projects nearly 50% of mining engineers will reach retirement age within a decade, while Australian accredited undergraduate mining graduates fell from 282 in 2015 to 68 in 2021 and most 2025 graduates now come from master’s programmes with uncertain local retention. Professor Andre van As notes that no top-10 mining school offers a dedicated underground mass mining or cave mining programme, and many academics and SMEs are already at or past typical retirement age. The South Gobi Underground Mass Mining Institute at Oyu Tolgoi, funded initially by Rio Tinto, offers a prototype: expert-taught, site-based cave mining training with professional certification, with AI used to capture and scale retiring specialists’ knowledge rather than replace it.

Autonomous deep-level mass caving at operations such as Oyu Tolgoi is driving a shift from tactile, face-level decision-making to remote system control, where engineers manage autonomous LHD fleets, ventilation-on-demand and microseismic arrays from virtual control rooms. Professor Khavalbolot Kyelgyenbai argues mining curricula must integrate AI, ML and control theory so students can interpret real-time data from thousands of sensors, apply stress–extraction relations such as Es = f(Ve, ΔK)·e^(σ1/σ3), and run neural-network-based hazard forecasting. Simulator-centric labs mimicking remote operation centres, with multi-screen cave digital twins and injected seismic or mudrush events, are positioned as core training tools at the Mongolian University of Science and Technology.

Raisebore stability assessment for deep caving operations is shifting from standalone empirical tools to integrated workflows that combine mXrap’s Raisebore Stability App (QR and MSUS from RMD data), Rocscience UnWedge and RocTunnel3 kinematic analyses, and calibrated numerical stress–deformation modelling. The approach targets long, deep raises in highly stressed, structurally complex ground, addressing mechanisms such as face unravelling, wedge failure, spalling and time-dependent degradation along the full raise alignment. For practitioners, this means earlier screening of raise locations, more defensible diameter and alignment selection, and clearer definition of support and monitoring requirements.

Mining education veteran and UWA Professor of Practice Richard Butcher reports that mining and geotechnical graduate salaries now commonly exceed AUD 150,000, driving annual intakes above 50 students and total school enrolments of 200–600, but straining teaching capacity and industry links. Higher mine-site pay means most staff now come from academic rather than operational backgrounds, prompting UWA to trial more “professors of practice” and expand structured industry liaison and vacation placements. Butcher expects AI tools such as Copilot to push curricula towards critical thinking, oral mine design assessments and extended 3‑year graduate training schemes.

The Australian Centre for Geomechanics’ Online Repository of Conference Proceedings now hosts almost 4,000 peer‑reviewed mining papers, including 3,909 ACG papers and MassMin 2020 and 2024, with total downloads surpassing 4 million and Caving/MassMin papers alone exceeding 500,000 downloads. Advanced search functions allow content-level queries, field- or conference-specific filtering (e.g. “underground” or Caving 2022), and DOI-based citation export for every paper. Authors retain copyright, while ACG holds proceedings rights and centralises online hosting, with DOIs encouraged for company sites and ResearchGate to maintain a single, persistent access point.

Jennmar has expanded dynamic ground support testing with the DIT105Z rig, which can load 3 m reinforcement tendons at up to 105 kJ and 8.6 m/s, and the new Alpha Dynamic Test Rig, a multi‑modal system delivering single impacts to 286 kJ under direct impact, momentum transfer and oscillatory loading. Laboratory work now uses standard jumbos for installation and full‑scale mesh tests to better mirror underground variability, feeding into interactive specification databases. These data are driving products such as the Falcon Bolt self‑drilling, fully tensionable, groutable tendon and pumpable resins like J‑Lok P, Marisil Thixo and Jennthix to support highly mechanised, dynamic ground conditions.

The US Department of Energy has awarded $29.5 million to 17 mining technology projects across 12 National Laboratories under the CMEI “Mine of the Future” initiative, targeting underground recovery, autonomous exploration, secondary sourcing, and advanced beneficiation. Idaho National Laboratory will trial electric‑hydraulic fracturing for in‑situ extraction, Lawrence Berkeley National Laboratory will test low‑voltage lithium recovery from clay, and Oak Ridge National Laboratory is building a mobile robotics platform to map underground mines in minutes. Argonne, SLAC and Ames labs will focus on extracting copper‑nickel‑cobalt from tailings, vanadium from ageing oil and gas infrastructure, and rare earths via acoustic–magnetic fracturing with computer‑vision sorting.

Robert Friedland is pushing to replace conventional SAG and ball mills with I-Pulse’s I-ROX pulsed-power comminution, which stores electricity then releases nanosecond–microsecond bursts to fracture ore internally along mineral boundaries, with projected energy cuts of up to 80% and about 5% higher metal recoveries. A 2,500 m² I-ROX research centre in Toulouse is testing Kamoa-Kakula copper ore and tailings, while I-Pulse has also secured a US$250 million CHIPS Act award for silicon-carbide semiconductors. The same platform underlies G-Pulse drilling, claimed to triple penetration rates and extend bit life sixfold, to be trialled on the Millungera Basin geothermal project in Queensland.

Government Actuary’s Department actuaries have delivered probabilistic analysis to the Office of Rail and Road on how climate-related hazards such as extreme rainfall, heat and flooding are evolving across UK rail and strategic road assets. Using long‑term climate projections and hazard frequency–severity modelling, the work maps where risks to embankments, cuttings, track buckling and drainage exceedances are likely to increase. The outputs will feed into ORR’s scrutiny of Network Rail and National Highways’ asset management, resilience upgrades and future capital planning.

Aston University is partnering with Jesmonite Ltd under an Innovate UK knowledge transfer partnership to redevelop Jesmonite’s low‑carbon acrylic, resin-based composites with added biochar as potential cement alternatives for façades and surface applications. Researchers from Aston’s Energy and Bioproducts Research Institute and Department of Civil Engineering will characterise the materials at molecular level and test mechanical and durability performance while targeting further reductions in embodied carbon. The work aims to move Jesmonite’s currently niche, film-set and design products into mainstream construction specifications, offering designers non‑cementitious façade and cladding options.

Geopolitical and economic uncertainty is pushing 61% of construction businesses to increase their commitment to innovation, according to Ayming’s International Innovation Barometer 2027. The survey points to firms prioritising digital tools, new construction materials and process optimisation to manage cost volatility and supply chain disruption. For civil and infrastructure engineers, this signals stronger client appetite for technologies such as BIM-based design coordination, offsite fabrication and alternative material specifications to de-risk programme and budget.

SuperCritical Materials Corp. has partnered with the University of Michigan to mechanically validate its uranium‑from‑seawater adsorbent for industrial‑scale offshore deployment, using hydrodynamic testing in the Aaron Friedman Marine Hydrodynamics Laboratory’s wave and current tanks. The programme will characterise the adsorbent under packing, deployment, ocean exposure and retrieval stresses, optimise packing configurations, and build and test prototypes for repeated deployment–recovery cycles. Findings will feed into a future feasibility study and nearshore pilot designs, targeting integration of seawater‑derived uranium into the US nuclear‑fuel supply chain.

The National Transport Research Organisation is expanding technical partnerships across Pacific nations to embed best-practice design, asset management and materials research into local road and bridge networks. Programmes include joint pavement investigations, climate-resilience assessments for coastal and low-lying corridors, and training on performance-based specifications for asphalt and sprayed seals under cyclone, flooding and high-salinity conditions. For geotechnical and civil teams, this means greater access to shared datasets, design tools and failure case histories tailored to volcanic soils, steep terrain and remote island logistics.

Brisbane will host the new Critical Metals for Critical Industries Cooperative Research Centre (CRC), based at the University of Queensland’s Brisbane City campus and initially targeting vanadium technologies. The CRC will link miners, processors, equipment suppliers, researchers and governments to fast‑track commercialisation of extraction, processing and downstream manufacturing technologies for critical metals supply chains. For geotechnical and mining engineers, this signals upcoming pilot‑scale projects, testwork and funding opportunities around vanadium deposits, tailings reprocessing and battery‑grade product specifications in Australia.

Geoscience Australia has mapped a 1000km continental-scale magmatic arc beneath the Delamerian project region spanning South Australia, New South Wales and Victoria, identifying concealed potential for critical minerals, copper and gold in previously under-explored terrane. Delivered as the first deep-dive study under the Federal Government’s 35-year Resourcing Australia’s Prosperity initiative, the work integrates deep-crustal geophysics and geochemistry to image mineral systems buried beneath thick cover. For explorers, the results materially expand prospective search space below cover sequences rather than in outcropping belts.

Plans for 1.5M new homes and multiple new towns in England risk locking in car dependency unless rail, bus rapid transit and active travel corridors are embedded in masterplans from day one, a University of Hertfordshire report warns. The study calls for safeguarded alignments for future rail stations, segregated cycleways and high-frequency bus routes to be fixed alongside land-use zoning, not retrofitted after plot-by-plot build-out. For civil and transport engineers, this signals earlier demand modelling, junction capacity design and multimodal access strategies at outline planning stage.

Tokamak Energy has completed a 14‑month test campaign on Demo4, its high‑temperature superconducting (HTS) magnet testbed in Oxford, aimed at validating magnet performance for compact spherical tokamak fusion reactors. The Demo4 system is designed to operate HTS coils at cryogenic temperatures while subjecting them to high magnetic fields and mechanical loads representative of reactor conditions, a critical step for future fusion power plant infrastructure. Results will inform structural design, thermal management and lifecycle performance of full‑scale HTS magnet assemblies for grid‑scale fusion demonstrators.

Eighty-three per cent of Britain’s cities – 59 urban areas – are classed as highly vulnerable to urban heat in new spatial analysis by Ordnance Survey, the Met Office and 4 Earth Intelligence. The dataset combines OS building footprints, surface cover and green space with Met Office temperature projections to map local heat exposure at street-block scale. For civil and geotechnical engineers, this points to urgent retrofit of shading, permeable and high-albedo surfaces, and revised pavement and rail design to cope with more frequent extreme surface temperatures.

Western Australia will invest more than $900,000 in five 2027 Minerals Research Institute of Western Australia (MRIWA) PhD scholarships targeting safer, more efficient and lower-emission mining across the state. The funded projects will focus on critical operational challenges in WA’s resources sector, including improved mine safety systems and productivity in high-tonnage operations. For engineers, the programme signals future research capacity in areas such as low‑carbon extraction methods, advanced geotechnical characterisation and process optimisation tailored to WA orebodies.

Two-phase flow between solid particles and interstitial air is shown to control how powders settle, discharge and move through hoppers, chutes and transfer points, with air pressure gradients often dominating behaviour in fine or aeratable materials. Jenike & Johanson’s microlearning session explains how phenomena such as flooding, ratholing and erratic discharge arise when air cannot escape freely, and why conventional single-phase flow assumptions fail. The content points engineers towards incorporating air permeation, deaeration and venting design into bulk solids handling calculations and equipment selection.

Decommissioning of Scotland’s first commercial wind farm, operated by ScottishPower, is being used as a UK-first testbed to align turbine end-of-life with material reuse and circular economy principles. Analysis of the dismantling process tracks recovery pathways for steel towers, concrete foundations and composite blades, examining options such as onshore recycling, repowering and secondary construction uses. Outcomes will inform future decommissioning strategies for UK wind assets, with direct implications for design-for-disassembly, waste permitting and contractual requirements on recyclability.

Adelaide University researchers are stress‑testing Australia’s transport networks against severe and extreme weather using the Federal Government’s first National Climate Risk Assessment (NCRA) as a baseline and extending it to state and council level assets. The work focuses on road and coastal infrastructure in councils such as the City of Holdfast Bay, examining failure modes under compound hazards like storm surge plus fluvial flooding and prolonged heatwaves. Findings are feeding into corridor‑scale adaptation options, including revised pavement design lives, drainage capacity upgrades and relocation or armouring of low‑lying links.

The US Department of Energy has awarded $10 million via the Critical Materials Innovation Hub to seven early-stage R&D projects targeting more efficient recovery and refining of rare earth elements, gallium, copper and other critical materials. Funded work includes chloride-based molten salt electrolysis for heavy rare earth production at Case Western Reserve, hydro and bio-hydrometallurgical copper extraction at Colorado School of Mines, and nanobubble–surfactant–reactive oxygen leaching of copper sulphides at the University of Arizona. FAST Metals, Indium Corporation, Oak Ridge National Laboratory and the University of Illinois will trial solid-phase extraction, advanced ion-exchange resins and redox-adsorbents to recover gallium and mixed rare earth oxides from bauxite-alumina circuits, zinc refinery residues and industrial byproduct streams.

Queensland’s five‑year major projects pipeline, detailed in the QMCA’s 2025 report, is being reshaped by Queensland University of Technology research targeting two critical constraints: labour productivity and cost escalation across road, rail and water schemes. QUT teams are deploying digital twins for corridor planning, AI‑based earthworks optimisation and sensor‑equipped pavements to cut rework and improve construction staging on multi‑billion‑dollar highway upgrades. For contractors, the work points to tighter programme control, more reliable cost forecasts and earlier geotechnical risk detection on large brownfield expansions.

Ideon Technologies will supply its compact borehole muon detectors to an international consortium attempting the world’s first high‑resolution muon imaging experiment powered solely by a laser‑plasma accelerator. The project aims to generate a high‑flux, tunable muon beam from a laser‑driven plasma source rather than a conventional synchrotron, enabling finer‑scale density imaging of ore bodies and underground voids. If beam stability and detector synchronisation targets are met, the approach could translate into faster, higher‑resolution subsurface imaging for mineral exploration, critical infrastructure assessment and nuclear security.

Cornish Lithium has secured a £7.2M UK Government DRIVE35 grant to fund drilling and reservoir testing at its Cross Lanes Geothermal Lithium Project near Chacewater, Cornwall. The funding will support additional deep geothermal boreholes targeting lithium-rich brines and associated heat, advancing data on permeability, flow rates and temperature profiles in Cornish granites. Outcomes will inform well design, surface infrastructure and potential co-production of low-carbon heat and battery-grade lithium, with direct relevance to geothermal resource appraisal and coupled geoenergy–mineral extraction schemes in fractured hard rock settings.

NMITE reports that its engineering undergraduates without A-level Mathematics are matching or outperforming peers with traditional maths and physics entry profiles on first-year assessments. The institute uses intensive “maths for engineers” bootcamps, problem-led studio teaching and continuous assessment instead of high-stakes exams to close gaps in calculus, statistics and mechanics. This challenges conventional Russell Group-style entry requirements and could widen the pipeline for civil, structural and infrastructure engineers if other providers adopt similar foundation-style models.

A new Critical Minerals in Ores – Mineral Chemistry database (CMiO-MIN), developed under the Critical Minerals Mapping Initiative partnership led by Geoscience Australia, compiles global mineral chemistry data to map how critical elements occur within ore minerals. The resource integrates mineral-scale compositional data across multiple deposit types and jurisdictions, giving explorers and survey agencies a consistent framework to compare occurrences and refine targeting models. For geoscientists and miners, it should sharpen geometallurgical predictions, improve resource assessments and support long-term supply planning for critical minerals.

CSIRO is running independent testing and verification of materials used in Australian road line markings, focusing on retroreflective glass beads and binder systems to maintain night-time visibility and durability on high-speed motorways. Materials Performance team leader Money Arora oversees laboratory assessment of bead size distribution, refractive index and coating adhesion against strict specification criteria before products are approved for use. The work directly affects pavement marking design life, maintenance intervals and performance under heavy traffic loading and UV exposure, especially on multilane arterial and freight routes.

Volta Metals has intersected broad gallium mineralisation up to 210 m beneath the current Springer open-pit shell in Ontario, with hole SL26-31 returning 399 m from 3 m downhole grading 51.8 g/t gallium oxide and SL26-33 cutting 399 m at 39.1 g/t gallium oxide and 0.248% TREO. A third hole, SL26-32, delivered 53.9 m from 372.1 m to 426 m at 1.22% TREO and 47 g/t gallium oxide, and 90% of 863 samples exceeded 30 g/t gallium oxide. Metallurgical work now focuses on gallium recovery, including bioleaching trials at Laurentian University and processing studies with Idaho National Laboratory, to justify adding gallium to Springer’s 56.6 Mt indicated and 119.5 Mt inferred rare earth resource in a planned update later this year.

The Democratic Republic of Congo has ordered systematic testing of cobalt hydroxide exports, mainly to China’s refineries that handle about 95% of global cobalt refining capacity, after a Nature Communications study estimated 2,000–5,000 tonnes of undeclared natural uranium left the country in cobalt shipments between 2000 and 2024. Researchers also estimate a further 1,000–4,000 tonnes may have entered tailings, prompting Kinshasa to plan radiation detectors on outbound trucks and seek an IAEA technical mission. Chinese operators grouped under USMCC deny excessive uranium levels, citing concentrations too low for economic recovery.

A new TESCAN Integrated Mineral Analyser (TIMA) at the University of Queensland’s Natural Resources Innovation and Characterisation Hub is providing high‑resolution mineralogical data on composition, grain size and texture from drill core and other mine samples. Led by Dr Pia Lois-Morales, the platform links automated mineralogy with geometallurgical and orebody models to track mineralogical variability across the life of mine. The aim is to tighten ore characterisation for mine planning, processing optimisation and tailings management by feeding consistent mineral data into decision workflows.
