Australia and the European Union are preparing to deepen cooperation on critical minerals through jointly supported projects spanning exploration, processing and downstream value chains. The partnership is expected to prioritise EU-listed critical raw materials such as lithium, rare earths and cobalt from Australian deposits, with a focus on traceable supply chains and ESG-compliant offtake. For miners and processors, this signals potential access to EU co-funding, long-term supply contracts and stricter reporting on emissions, waste and community impacts.

The Global Resources Innovation Expo 2026 (GRX26) will run in Perth from 5–7 May 2026, positioning Australia’s mining and METS sector as host for a concentrated three‑day programme of technology, equipment and services. Organised by AusIMM, the event is expected to draw international operators, OEMs and technology vendors to showcase advances in areas such as automation, digital mine planning and mineral processing equipment. For engineers, GRX26 offers direct access to suppliers and case studies relevant to brownfield optimisation, remote operations and decarbonisation projects.

Fortescue has ended its legal action against three former senior executives who left to found green iron start-up Element Zero, reaching a confidential settlement and dropping claims over alleged misuse of confidential information. The dispute centred on Fortescue’s own green iron ambitions within its Fortescue Energy division and concerns that Element Zero’s technology development could overlap with internal decarbonisation work. Resolution removes a potential constraint on Element Zero’s fundraising and technology partnerships while clarifying competitive boundaries for green iron process development in Australia.

SolGold has set 2026 for early works at its Cascabel copper-gold project in northern Ecuador, fast-tracking site preparation, resource drilling and a two-unit corporate restructuring to target first production in 2028. The revised schedule focuses on accelerating enabling works for underground development and surface infrastructure while separating exploration and project development into distinct business units. For engineers and contractors, the timeline signals upcoming demand for geotechnical investigations, access roads, platforms and early civils to support mine construction within a compressed pre-production window.

Aya Gold & Silver has reported its strongest intercept to date at the Boumadine polymetallic project in Morocco, with both infill and step-out drilling returning high-grade silver, gold, zinc and lead over significant widths. Recent holes along the Main Trend and South Zone are extending mineralisation beyond the current resource envelope while tightening drill spacing in the central area for an updated estimate. An analyst notes that results to date support further resource growth, signalling upside for future mine planning and metallurgy work.

A 1,971‑kilogram silver bullion bar measuring 1.3 metres in length has been unveiled in Dubai, setting a new Guinness World Record for the largest silver bar. The record piece, cast as a single ingot, far exceeds standard 1,000‑oz (c. 31 kg) London Good Delivery bars, illustrating the casting and handling challenges of producing and moving nearly 2 tonnes of refined silver in one block. For miners and refiners, it serves mainly as a marketing and metallurgical showcase rather than a practical trading unit.

Canada has ordered a national security review of the proposed US$53 billion merger between Teck Resources and Anglo American under the Investment Canada Act, Industry Minister Mélanie Joly confirmed. The review adds regulatory uncertainty and potential delay to combining Teck’s steelmaking coal and copper assets with Anglo’s global portfolio, which includes major operations in Chile, South Africa and Australia. Any conditions imposed could affect future capital allocation, mine divestments and approvals for large-scale brownfield and greenfield expansions in Canada.

Eldorado Gold has increased proven and probable reserves by 5%, reporting 371.7 million tonnes at 1.05 g/t for about 12.5 million oz of contained gold as of end-September. The update materially extends mine life across its portfolio, with the grade sitting in the typical range for large open-pit and underground gold operations. Geotechnical and mine planning teams will need to revisit pit shells, underground stope designs and long-term tailings and waste storage requirements to accommodate the larger reserve base.

Rio Tinto is preparing to sell its US boron assets, which Bloomberg values at up to $2 billion, signalling a potential exit from one of the world’s key borates supply centres. The portfolio is expected to include the long‑life US Borax operations in California’s Mojave Desert, a major source of refined borates used in glass, ceramics and fertilisers. Any sale would reshape the borates market and could alter long‑term offtake, logistics and processing strategies for downstream industrial users.

Torrential monsoon rainfall over the past week in North Sumatra has triggered debris-laden flash floods and multiple landslides, killing at least 10 people and leaving six missing in districts including Toba and Samosir. Police and BNPB teams report riverbank failures and slope collapses along road corridors and near settlements, with access to several upland villages cut by washed-out embankments and blocked mountain passes. For geotechnical and civil engineers, the events point to highly saturated residual soils, inadequate slope drainage, and vulnerable transport links in steep catchments during peak monsoon conditions.

Keller has completed a ground improvement scheme for Encinal High School Stadium in Alameda, California, collaborating with the project geotechnical engineer to satisfy California Geological Survey seismic requirements. The solution, delivered as part of a larger stadium renovation, used ground improvement to mitigate liquefaction and lateral spreading risks identified in the site’s young bay mud and loose granular fills. For practitioners, the project shows how early contractor–engineer integration can tailor seismic ground improvement to school facilities on soft, seismically active coastal deposits.

Cutting-edge 3D geological modelling for the Vienna metro extension now covers roughly half the city, integrating borehole logs, historic excavation records and geotechnical lab data into a single subsurface model. Presented at the World Tunnel Congress, the workflow supports alignment selection, station box siting and tunnel support classes by quantifying uncertainties in soil and rock units, groundwater conditions and fault zones. For designers and contractors, the model is being used to refine excavation sequences, reduce geotechnical risk allowances and justify design decisions to the client.

Tilbury Douglas has begun a £14m project to convert an existing building in Coventry into a community diagnostic centre (CDC) for NHS Property Services and University Hospitals Coventry & Warwickshire NHS Trust. The facility, located near the Coventry Urgent Treatment Centre, GP practices and mental health services, is designed to handle around 90,000 patients annually and deliver up to 75,000 additional diagnostic tests a year for conditions including cancer and heart disease. Opening is targeted for late 2026, with a brief for a modern, energy-efficient healthcare facility.

Expansion of the UK Boiler Upgrade Scheme now offers a £2,500 grant for air-to-air heat pumps alongside the existing £7,500 support for air-source and ground-source units, making domestic air-conditioning eligible for government funding for the first time. Carrier Solutions UK, distributor of Toshiba systems, expects this to catalyse a residential air-conditioning market, particularly in flats and apartments currently using direct-electric or storage heating. Multi-split air-to-air systems, with one outdoor unit serving several rooms, are positioned as a practical retrofit route where conventional air-to-water heat pumps are hard to install.

Work has started on Baltic Wharf in Bristol, where The Hill Group and Goram Homes will build 166 harbourside homes on a complex brownfield site on Spike Island, backed by a £2.4m Brownfield Land Release Fund grant. The scheme delivers 66 affordable units owned by Sovereign Network Group, including 50 for social rent and 16 for shared ownership, giving a 40% affordable housing mix. Plans also reopen a previously restricted waterfront, reconnecting the River Avon to the Floating Harbour with new pedestrian links, public realm, café and flexible commercial space, with first homes due spring 2027.

Mace will start main works in early 2025 on Helical’s £200m, 235,000 sq ft over-station office scheme above Paddington station, a 19-storey Grimshaw-designed canalside building with 15 office floors and ground-floor retail, now targeting completion in Q3 2028 instead of Q4 2028. Preparatory works are already under way ahead of formal site acquisition in January 2026, with Helical developing the project in joint venture with Places for London. Helical has also agreed heads of terms for forward funding a 429-studio student block above Southwark Tube and forward sale of 44 affordable homes to Southwark Council, with construction planned from H1 2026 to 2029.

A Northampton roofing contractor has been fined £16,650 after a 31-year-old employee fell more than three metres through an uncovered skylight opening while re-covering a single-storey flat roof on Sywell Road, suffering injuries requiring surgery and long-term treatment. Health & Safety Executive investigators found Kingsley Roofing Contractors Limited had not properly planned work at height or installed effective fall-prevention measures around two large skylight openings. The firm pleaded guilty to breaching Section 3(1) of the Health and Safety at Work etc Act 1974 and was ordered to pay £7,205 in costs plus a £2,000 victim surcharge.

Former Association of Mining and Exploration Companies South Australian director and 20‑year resources veteran has been appointed to the state’s new Coexistence board, set up to manage land access tensions between miners, farmers and other land users. The board is expected to advise on approvals and conditions for exploration and mining leases, with a focus on coexistence on freehold and pastoral land. For project teams, this signals closer scrutiny of stakeholder engagement, surface access agreements and disturbance footprints in South Australia.

Global bauxite production is forecast to grow in 2025, but analysts warn that political instability and recent export disruptions in Guinea – which supplies more than a quarter of seaborne bauxite – could tighten alumina refineries’ feedstock security. Australia, producing around 100Mtpa from large open‑cut operations in Queensland and the Northern Territory, is expected to provide stable output and shipping, with no major greenfield capacity changes flagged. Any prolonged Guinean constraint would likely redirect Chinese and Middle Eastern offtake towards Australian and Indonesian ore, affecting contract terms and freight dynamics.

Rio Tinto and Viva Energy have completed a large-scale renewable diesel trial, showing haul trucks and other heavy mobile equipment can switch from conventional diesel with no changes to engines, fuel systems or maintenance schedules. The trial used drop-in hydrotreated vegetable oil (HVO)-type fuel in standard high-horsepower mining fleets, validating cold-start performance, fuel consumption and engine wear against OEM limits. Results indicate sites with existing diesel storage and distribution can cut Scope 1 emissions from mobile equipment rapidly by substituting fuel rather than retrofitting fleets.

Timken is promoting a broad portfolio of housed bearing units for mining applications, including solid-block spherical roller units and split-block designs aimed at high-load, contaminated environments on conveyors, crushers and vibrating screens. The units typically integrate triple-lip or labyrinth seals, ductile iron or cast steel housings and factory-set clearances to cope with misalignment, shock loads and abrasive fines common in fixed plant. For maintenance teams, the focus is on longer relubrication intervals, reduced unplanned stoppages and easier swap-out in cramped, dirty locations.

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.

Power cuts linked to Western Power’s Eastern Goldfields load permissive scheme have disrupted operations at Lynas Rare Earths’ Kalgoorlie cracking and leaching plant, forcing temporary shutdowns of high-voltage equipment. Canaccord Genuity warns that repeated grid instability could delay ramp-up to nameplate capacity and pressure fiscal-2026 earnings, given the plant’s role in replacing Malaysian cracking capacity. The broker notes that any prolonged derating of electrical supply or need for additional backup generation would raise operating costs and complicate process stability for heat- and power-intensive circuits.

Matthews Brothers Engineering is expanding its range of asphalt and aggregate spreader box units, pairing them with a state-of-the-art manufacturing facility to improve build precision and consistency. The spreader boxes are engineered to suit a variety of truck and vehicle configurations, allowing contractors to retrofit existing fleets rather than procure dedicated plant. For pavement and surfacing crews, this flexibility can tighten layer thickness control and edge definition on spray seal and asphalt works, with direct implications for ride quality and reduced rework.
