Rio Tinto is sourcing large mining tyres and conveyor belts from Chinese manufacturers for the Simandou iron ore project, citing faster lead times and more flexible logistics than traditional Western suppliers. Chinese technology vendors are also offering circularity options, such as tyre recycling and conveyor belt reprocessing, positioning themselves as long-term strategic partners rather than purely low-cost providers. For mine planners and maintenance teams, this signals broader acceptance of Chinese-origin critical consumables in high-profile greenfield developments.

The Office for Environmental Protection has issued formal notices to Defra and the Environment Agency over suspected failures to comply with regulations transposing the EU Water Framework Directive into UK law, signalling potential systemic issues in river basin and groundwater quality management. The case centres on how environmental objectives, monitoring and classification of water bodies have been implemented, including the setting of chemical and ecological status under the WFD regime. Civil and water engineers should expect closer scrutiny of discharge permits, combined sewer overflow operation and design standards for future catchment and treatment schemes.

UK ministers have pushed back the Development Consent Order decision for the two 1.5GW Dogger Bank South offshore wind farms, extending the statutory deadline from 10 January 2026 to 30 April 2026. The schemes, totalling 3GW in the North Sea, would require extensive offshore foundations, subsea cabling and grid connection works comparable in scale to the existing Dogger Bank A, B and C projects. The four‑month delay prolongs design and procurement uncertainty for marine geotechnical campaigns, fabrication yards and onshore grid reinforcement planning.

MPs have sharply criticised Thames Water’s performance in a Commons debate, with one MP saying she “wouldn’t trust Thames Water to run a bath” as they examined the company’s financial stability and pollution record across London and the Thames Valley. The session scrutinised the utility’s remediation plans for sewage discharges into the River Thames and its ability to fund long-term upgrades to ageing sewers and treatment works under its current debt-laden structure. For civil and water engineers, the outcome could reshape investment timing, regulatory requirements and delivery models for major network rehabilitation schemes.

A coalition of UK environmental professionals is calling for natural capital – including rivers, wetlands, soils and urban green space – to be formally designated as critical national infrastructure (CNI). The group argues that assets providing flood attenuation, coastal protection and urban cooling deliver system-level resilience comparable to power, water and transport networks, and should therefore receive similar statutory protection and long-term funding. For civil and geotechnical engineers, this would push nature-based solutions such as floodplains, saltmarsh and sustainable drainage systems further into core infrastructure planning and asset management.

Gold could spike to $5,050/oz in the first half of 2026 before potentially correcting to as low as $3,950/oz later in the year, according to HSBC’s latest forecast, which assumes elevated geopolitical risk and ongoing US Federal Reserve rate cuts. The bank now projects an average 2026 price of $4,587/oz and an end‑2026 level of $4,450/oz, with “high volatility” driven by central bank buying, a weaker US dollar and flows into gold‑backed ETFs. Longer term, HSBC lifts its average forecasts to $4,625/oz for 2027, $4,700/oz for 2028 and $4,775/oz for 2029.

Lundin Mining has filed for Chilean environmental approval for a US$150 million upgrade at the Caserones copper-molybdenum mine, aiming to maintain current production and fresh water use while extending operating continuity to 2039. The project adds new access roads, a fresh water reservoir, two backup sulphuric acid storage tanks, and a 90 Mt increase in heap leach capacity, while extending operations at the existing solvent extraction–electrowinning plant. Caserones currently processes about 84 Mt/a of ore with 100,000 t/d milling capacity and up to 35,000 t/a cathode output, but faces declining grades and lower production from 2027.

Rio Tinto is considering temporarily owning Glencore’s coal business, including the Ulan complex and Teck-acquired assets, to clear a key hurdle in buyout talks that could create a $207 billion mega-miner and the world’s largest listed mining company. One option under discussion is Rio acquiring all of Glencore, then later divesting coal while retaining the $1.4 billion‑EBIT first-half 2024 marketing division, which Goldman Sachs values at up to $4 billion by 2030. Analysts expect significant portfolio reshuffling, with copper the core rationale as combined 2026 copper output could exceed 1.6 million tonnes.

La Mancha Resource Capital has sold a 3.5% stake in Endeavour Mining via a C$71.25-per-share bought deal worth about C$605 million, cutting its holding from roughly 15% to 11% while retaining board representation through Naguib Sawiris. Endeavour, now valued around C$17.5 billion after a 191% share price rise in 12 months, produces in the mid- to high-900,000-oz.-per-year range from West African assets including Houndé (Burkina Faso) and Ity and Agbaou (Côte d’Ivoire). The move comes as Burkina Faso has nationalised Endeavour’s former Boungou and Wahgnion mines, paying about $80 million and asserting full state control.

US President Donald Trump and Congress are moving to overturn Joe Biden’s 20‑year mining ban on more than 225,000 acres of Superior National Forest in northern Minnesota, using the Congressional Review Act after Interior officials argued the ban was not properly filed in the Congressional Record. If lawmakers reject the ban within 60 days, the Trump administration could reissue long‑contested federal leases for Antofagasta’s Twin Metals underground copper‑nickel‑cobalt‑PGM project, located in the Duluth polymetallic belt. The mine would be Minnesota’s first underground operation since 1967 and the next major US nickel producer as the country’s only existing nickel mine nears closure.

A $3.6 million Arbor-funded University of Arizona Tailings Center project, led by mining engineer Dr Isabel Barton, is evaluating whether 17.5 billion tons of historic copper tailings in Arizona—growing by ~100 million tonnes per year—can be reprocessed to recover critical minerals and reduce environmental risk. The team is combining statewide and UAV-based remote sensing, industry tailings datasets, drilling and surface sampling, mineralogical characterisation and techno-economic analysis using magnetic separation and basic leaching. Early work has identified unexpected mineral occurrences, including arsenic, zinc and possibly tungsten, which could justify flowsheet changes to keep these elements out of future tailings.

Construction and maintenance specialist Trail Group has appointed David Humphrey as operations director and board member, tasking him with leading operational teams and managing the company’s financial performance. Humphrey brings 25 years’ experience delivering major projects with Berkeley Homes, St Edward Homes, Ardmore and Galliford Try, and joined the Swanley-based firm in September 2025. His remit covers expanding Trail’s fire safety and building maintenance/refurbishment services across public sector frameworks and new work with developers, social landlords and commercial clients.

Bovis Construction (Europe) has appointed former John Sisk & Son healthcare sector lead Nadeem Chaudhry as head of health for its UK operations to accelerate expansion in NHS and private healthcare projects. Chaudhry previously helped secure major schemes including the Lewisham Hospital theatres and infrastructure upgrade and the Evelina Hospital cancer centre, and has held senior roles at Kier, Vinci and Osborne. Bovis aims to leverage his experience with demanding NHS frameworks to grow its healthcare portfolio and deepen long-term client relationships.

Persimmon has signed a group-wide contract to deploy Nexus ReGen’s Materials Exchange Platform across all UK regional businesses, listing import and export needs for soils, aggregates and other heavy materials on hundreds of live projects. A multi-project trial included one scheme achieving a 43% cost saving by reusing surplus topsoil locally, pointing to potential diversion of millions of tonnes of material from landfill and reduced primary aggregate demand. For engineers, earlier visibility of cut-and-fill and surplus streams should tighten earthworks balance, cut haulage miles and support carbon-reduction targets.

Mott MacDonald has appointed Paul Bentley, long‑serving director of its contracting arm JN Bentley, to its executive board while he continues to lead the integrated design-and-build business Mott MacDonald Bentley (MMB). Under Bentley’s leadership, MMB has become a major UK water-sector contractor delivering complex civils and MEICA works for clients including Yorkshire Water, Anglian Water and Northumbrian Water. The move signals stronger board‑level representation for design-and-build delivery, with an emphasis on operational performance, safety culture and long-term framework relationships in regulated water infrastructure.

Builders’ merchants face a prolonged flat market as the Builders Merchants Federation cuts its 2025 sales growth forecast from 2.5% to 1.4% and trims 2026 expectations from 3.1% to 2.3% after a weak Q3 2025. The BMF Winter Forecast Report now brackets 2026 growth between 1.2% and 3.7%, with the upper bound dependent on government stimulus for house-building and domestic repair and maintenance. Chief executive John Newcomb points to stalled housing starts, depressed RMI demand and high interest rates, calling for rate cuts, first-time buyer incentives, brownfield release and delivery of the Social and Affordable Housing Programme.

Leeds United has secured planning permission to expand Elland Road from under 38,000 to 53,000 seats by redeveloping the West and North Stands, upgrading the ground to UEFA Category 4 status for major international fixtures. Architect KSS and engineer Buro Happold will deliver a phased build, with enabling works starting immediately and main construction beginning this summer while the stadium remains operational for home matches. The scheme is positioned as the first phase of wider regeneration around Elland Road, with Leeds City Council and National Highways involved in access and neighbourhood planning.

Stark Building Materials UK has appointed former HSS Hire managing director Fiona Perrin as managing director of Jewson Partnership Solutions, which supplies materials and services to public sector and social housing clients. Perrin, who has chaired the Independent Builders Merchant Group and served as a non-executive director at Coastline Housing and fire-door manufacturer Sentry Doors, will report to Stark UK chief executive John Carter and join the UK executive team. The reorganisation also sees chief logistics officer Ranald Forbes support Jewson Major Build Solutions, while national operations director Neil Grindley assumes responsibility for Jersey-based Normans.

Metso has secured a ~€180 million ($210 million) contract to supply engineering and key process equipment for a new primary copper smelter complex in Asia designed to produce 300,000 t/y of copper cathodes and 1.1 Mt/y of sulphuric acid. The scope covers core smelting and off-gas handling technology, positioning the plant for high-acid capture rates critical for SO₂ emissions control. For project teams, the scale implies substantial concentrate throughput and significant integration requirements with downstream acid and cathode handling infrastructure.

Cavotec has secured a second contract with Civmec to supply a motorised cable and hose reel package for Port Hedland, one of the world’s largest iron ore export hubs in Western Australia. The system will provide automated, controlled reeling for high-voltage power cables and dust suppression hoses, supporting continuous shiploading and bulk handling operations in a highly abrasive, saline environment. For engineers, the package signals further integration of dedicated reeling infrastructure into port materials-handling layouts to reduce manual hose handling and improve uptime on critical loading assets.

Warrior Met Coal has completed its $1 billion Blue Creek longwall mine in Tuscaloosa County, Alabama, targeting premium high-vol A metallurgical coal for global steel producers. The underground operation, developed as a standalone longwall complex, is designed around modern high-capacity longwall systems and associated ventilation, materials handling and coal preparation infrastructure. State and local officials, federal delegation staff and US Bureau of Land Management leadership attended the opening, signalling long-term regulatory and political backing for the project’s production and employment footprint.

Laing O’Rourke, in the MetroVista joint venture led by Gamuda, has secured the Stations Package West on the Sydney Metro West scheme, covering five new underground stations including the first heavy rail link to Five Dock. The package spans design and construction of station boxes, fit-out and interchange works along the 24km, twin-tunnel metro between Greater Parramatta and the Sydney CBD. Contractors will need to manage complex urban excavation, interface with existing utilities and roads, and tight staging to integrate with previously awarded tunnelling contracts.

Subsidence Security Guidance 2025, issued as a technical standard for UK mining operators, is being interpreted as a de facto national benchmark for managing ground movement risk across transport, energy and water infrastructure. The framework pushes asset owners to map legacy mine workings, karst and compressible soils, integrate continuous ground monitoring (InSAR, LiDAR and automated levelling) and link trigger thresholds directly to asset management plans. For geotechnical and structural engineers, it signals closer regulatory scrutiny of differential settlement, serviceability limits and resilience of buried pipelines, foundations and trackbeds.

A £61M digital resignalling upgrade on the West Coast Main Line through Carlisle has been completed, targeting improved reliability on this key north–south rail artery. Network Rail has replaced life-expired lineside signals with modern, interlocked control systems and upgraded trackside equipment over multiple possessions, integrating the section into a centralised signalling centre. The scheme reduces signal failures and maintenance interventions, with implications for future ETCS deployment and tighter headways on one of Britain’s busiest mixed-traffic corridors.
