Satellite analysis of more than 16,700 US dams shows over 2,500 structures are both in poor condition and classified as high-hazard potential, meaning failure would likely cause loss of life. Geoscientists report many of these ageing embankment and concrete gravity dams lack adequate spillway capacity, suffer from seepage and erosion issues, and sit downstream of growing urban development. The findings point to large unfunded backlogs in dam safety upgrades, with implications for risk-based inspection, emergency drawdown planning and prioritisation of remedial works.

The International Society for Soil Mechanics and Geotechnical Engineering, via the International Journal of Geoengineering Case Histories, has opened a call for papers for a Special Issue on “Geo-Hazards: Lessons from the Ground”. Submissions are sought on documented case histories of landslides, liquefaction, sinkholes, tailings failures and other geo-hazards, emphasising in-situ data, back-analyses and performance of mitigation works. The issue targets practice-oriented lessons for design, monitoring and risk management, with detailed ground investigation records and instrumentation results strongly encouraged.

Western Australia is being tipped for a modern gold rush after geoscientists identified a major new exploration development, with state-scale datasets revealing previously overlooked greenstone belts and structurally complex shear zones prospective for orogenic gold. The breakthrough centres on integrating high-resolution aeromagnetic surveys with deep-crust seismic profiles to map concealed Archean terranes beneath thick regolith cover. For miners and explorers, the work points to new drill targets beyond mature camps like Kalgoorlie, with implications for revising prospectivity models and reallocating exploration budgets across the Yilgarn Craton.

Korean researchers led by Seungho Lee at Jeonbuk National University map five distinct lithium governance models in Chile, Argentina, Brazil, Bolivia and Mexico, linking them to commodity price cycles, geopolitical competition and the maturity of each country’s lithium industry. Chile’s hybrid regime with strong state oversight contrasts with Argentina and Brazil’s decentralised, market-led systems, Bolivia’s tightly controlled state-led model and Mexico’s largely rhetorical nationalisation stance. The two-stage decision-making framework signals that miners, battery manufacturers and state-backed investors must tailor project, offtake and JV strategies to country-specific political settlements rather than apply a single Latin America playbook.

Deep-sea mining tests in the Clarion–Clipperton Zone at 4,280 metres depth, commissioned by Nauru Ocean Resources (a The Metals Company subsidiary), cut macrofaunal density by 37% and species richness by 32% along machine tracks over two years, based on disturbance of 3,000 tonnes of polymetallic nodules. European researchers from the Natural History Museum, University of Gothenburg and the National Oceanography Centre collected 4,350 sediment macrofaunal animals and identified 788 species, mainly polychaete worms, crustaceans and molluscs. The trial used machines only about half the size of planned commercial systems, raising concern that full-scale operations could cause larger, possibly irreversible, benthic impacts.

Geoscience Australia has drilled a 3023‑metre stratigraphic hole in the South Nicholson Basin, pushing national pre‑competitive geoscience to new depths in the hunt for salt and critical minerals. Core and downhole geophysics from the ultra‑deep bore will refine basin architecture, fluid pathways and evaporite distribution models that guide potash, lithium brine and sediment‑hosted base metal exploration. For miners and consultants, the dataset should tighten depth predictions, reduce drilling risk and sharpen targeting in underexplored central Australian basins.

New research on Australian expansive clays warns that more frequent intense rainfall and drought cycles are accelerating differential movement and cracking in lightweight buildings, pavements and transport corridors founded on shrink–swell soils. The work points to heave and settlement driven by deep moisture fluctuations, with particular concern for lightly loaded slabs, shallow footings and low-volume roads where historical climate data underestimates design suction changes. Engineers are urged to revisit site classification, footing depth, drainage and moisture barriers, and to integrate updated climate projections into geotechnical design for new and existing assets.

A new ARC Research Hub for Smart Process Design and Control has been launched at Monash University to cut emissions from steelmaking, which currently accounts for about 8% of global CO₂ output and 18–20% of Australia’s export income via iron ore. The Hub links Monash, Macquarie, Queensland, UNSW and Western Sydney University with Rio Tinto, Baowu Steel and China Steel Corporation to develop AI- and simulation-driven, low-emission processes tailored to diverse Australian ores. More than 100 technical presentations from Australia, China and Korea marked the launch at a three-day conference.

New research from Sandvik’s global engineering group points to a shrinking pipeline of mining engineers, with survey data showing young professionals rank decarbonisation projects, automation and digital systems above traditional pit or plant roles. Respondents cited reluctance to work FIFO rosters and in remote camps, and a preference for hybrid city-based roles linked to remote operations centres and OEM technology hubs. Sandvik argues miners must redesign graduate pathways around battery-electric fleets, data analytics and equipment condition monitoring to compete with infrastructure, renewables and tech employers.

Two thirds of infrastructure investors are walking away from UK projects because the business case “doesn’t stack up”, despite a strong short- to medium-term project pipeline, according to new research. The report warns of a finite window to de-risk schemes by improving planning certainty, revenue models and long-term policy stability, or capital will shift to competing markets. For engineers, this signals tougher scrutiny on demand forecasts, cost escalation assumptions and risk allocation in PPP and regulated-asset projects.

Researchers at New York University Abu Dhabi report Curiosity rover evidence that liquid water once flowed beneath aeolian dunes in Gale Crater, forming cemented crusts and polygonal fracture networks in fine-grained sandstones. High-resolution Mastcam and ChemCam observations show cross-bedded units with indurated tops and moisture-related diagenetic features consistent with shallow subsurface flow rather than surface runoff. For planetary geotechnics, the work implies past groundwater-driven cementation, altered shear behaviour of dune-derived sediments, and more complex subsurface stratigraphy relevant to future drilling and in situ construction on Mars.

A new algorithmic framework from MIT identifies the smallest “core” dataset needed to guarantee optimal solutions in structured decision-making problems such as geotechnical design under uncertainty. The method uses combinatorial optimisation to strip large datasets down to a minimal subset that still preserves the same optimal decision, reducing computation while maintaining solution quality. For geotechnical engineers running probabilistic slope stability, foundation or tunnel support analyses, this could cut Monte Carlo or scenario runs without sacrificing reliability in design outcomes.

Indium recovered from existing mine waste streams could underpin a domestic Australian solar PV manufacturing sector, with a new study pointing to tailings from zinc and lead operations as a major untapped source. Researchers note that indium is a key component in indium tin oxide (ITO) coatings for high‑efficiency thin‑film cells, yet Australia currently exports concentrates and imports finished solar modules. The work signals opportunities for retrofitting hydrometallurgical circuits at established base‑metal plants to extract indium, adding revenue while reducing long‑term tailings liabilities.

Intelligent GNSS slope monitoring systems in open cut mines are moving from intermittent logging to permanently powered operation, collecting one position every 10 seconds and using interquartile filtering to deliver millimetric precision beyond standard centimetre-level RTK. Embedded software rejects outliers beyond 1.5–3 × IQR, routinely detecting 1–2 mm movements and generating multi-tiered products such as 5-minute (≈60-epoch) and 24-hour (≈8,640-epoch) averages. Time-series analyses show rolling 24-hour averages can cut detection lag by 40–60% for non-linear deformations, though longer 48-hour and weekly windows risk masking rapid, rainfall- or blast-driven accelerations.
