Hyundai Construction Equipment has appointed Hodge Plant as its dealer for Scotland, with coverage across the country except Dumfries and Galloway and initial sales, parts and service run from Hodge’s main Hamilton workshops. A new Stirling/Northern depot, with building works already underway and completion targeted for spring 2027, is intended to strengthen support for central, northern and rural regions via an expanded sub-dealer network. Hodge currently fields four road-based service engineers, backed by fabrication and in-house paint facilities, signalling increased local capacity for heavy equipment maintenance.

Thames Water has appointed Barhale to deliver Phase Three of the £17m Greenwich Trunk Main, installing the final 1km of ductile iron pipeline by open-cut from the Blackwall Lane roundabout to the O2 arena and connecting 350mm–800mm diameter sections to the existing 800mm main at Croon’s Hill. Barhale and specialist contractor Suez will commission the 4km main using ice pigging rather than swabbing and high-velocity flushing, saving about 1.8m litres of water and cutting required pits from 25 to six. The approach trims project costs by roughly £800,000, reduces carbon and brings forward commissioning of Phases Two and Three to May 2027.

British Land has awarded McLaren a £99m design-and-build contract to retrofit and expand the late-1970s West One building above Bond Street Underground Station into 93,517 sq ft of premium offices over seven storeys. The scheme retains around 60% of the existing concrete frame, adds three extra office floors using a lightweight steel structure from second floor upwards, and reconfigures the block to two retail levels (basement and ground) with offices from first to seventh floors. Targeting NABERS 5*, BREEAM Excellent, EPC A and WELL Enabled, the project is constrained by a dense tunnel network, limiting new foundations to a single concrete core.

Mexico City’s subsidence has been mapped in new detail by the NASA–ISRO NISAR L-band radar mission, revealing metropolitan zones sinking by more than 50cm per year over clay-rich former lakebed deposits. Interferometric SAR time-series show differential settlement across key infrastructure corridors, with some districts exhibiting cumulative subsidence of several metres over recent decades, far exceeding typical building serviceability limits. The data set offers geotechnical engineers block-scale deformation rates to refine foundation design, tunnel and metro monitoring, and groundwater extraction management.

Rosh Pinah Zinc and Appian Capital Advisory have commissioned a new process water treatment plant at the Rosh Pinah mine in Namibia as a core element of the RP2.0 expansion. The plant is engineered to retreat and recycle process water from multiple circuits across the operation, cutting freshwater draw and reducing discharge volumes to the site’s TSF and evaporation facilities. For mine planners and process engineers, the scheme tightens the site water balance and may enable higher throughput under existing abstraction permits.

Shuanglin has unveiled an autonomous, battery-electric multi-axle mining truck using distributed drive technology, entering a niche previously explored by China Space Sanjiang Group’s 220 t WTW220E (16 wheels in eight pairs) and ETF’s 218 t MT-240. The new platform targets ultra-heavy haul with multiple driven axles to spread ground pressure and improve traction on weak pit floors, while removing the mechanical drive train. For mine planners and geotechnical teams, such configurations could materially change haul road design, turning radius constraints and underfoot bearing capacity assumptions.

Ivanhoe Electric plans to acquire Robbins’ purpose-built Crossover XRE tunnel boring machine and material handling system, previously used at Anglo American’s Grosvenor coal mine, for its Santa Cruz copper project in Arizona. The mixed-face XRE TBM is designed to handle both hard rock and soft ground, allowing continuous, segmentally lined access tunnels instead of conventional drill-and-blast shafts. For geotechnical and mine development teams, this signals potential for faster, lower-disturbance underground access in complex ground conditions typical of Arizona copper deposits.

£20M of National Highways upgrades on the A21 between Hastings and Flimwell are being criticised by local MP Huw Merriman for failing to tackle what he calls the “underlying cause” of serious collisions on the single-carriageway sections. Works reportedly focus on resurfacing, signage and minor junction changes rather than full dualling or major realignment of substandard bends and short sightlines. For designers and safety engineers, the row centres on whether incremental measures can manage overtaking and speed-related crash risk without a more fundamental geometric redesign.

Passenger services at the new £250M Cambridge South station will start on 28 June, providing direct rail access to the Cambridge Biomedical Campus and linking into the existing West Anglia Main Line. Designed as a four-platform interchange between London–Cambridge–Ely services and local stopping trains, the station is planned as the first operational site under Great British Railways, integrating track, station and timetable management. For civil and rail engineers, the scheme sets a template for campus-adjacent infill stations with high passenger throughput and constrained urban footprints.

Peru’s 7 June presidential runoff between leftist Roberto Sánchez and conservative Keiko Fujimori is jolting markets and putting roughly $6 billion in annual mining investment at risk, with Peru’s sol and dollar bonds already underperforming and Barclays advising investors to go underweight. Sánchez is proposing higher mining taxes, constitutional reform, a phase-out of open-pit mining and potential use of international reserves for social spending, directly threatening large copper and gold operations run by Glencore, Anglo American, Freeport McMoRan, MMG and Fortescue’s newly acquired Cañariaco project. At the same time, illegal miners are now believed to produce more gold than formal operators such as Hochschild, Buenaventura and Newmont, raising operational and permitting uncertainty even if a business-friendly Congress tempers more radical policy shifts.

Fortescue has been ordered by the Federal Court of Australia to pay more than A$150 million (US$108 million) to the Yindjibarndi people for “significant damage” to cultural heritage sites caused during operations at its Solomon Hub iron ore mine in the Pilbara. The ruling, which also includes A$100,000 for economic loss, follows a native title dispute dating back to a 2003 claim and the Yindjibarndi’s 2017 grant of exclusive rights over a 2,700 sq km, iron ore-rich area. For miners, the case signals materially higher native title compensation exposure and ESG risk where projects pre-date or contest Indigenous land determinations.

Elevra Lithium has secured a A$441 million (US$318 million) funding package, including a fully underwritten A$275 million placement and up to C$145 million in convertible notes from the C$15 billion Canada Growth Fund, to expand its North American Lithium (NAL) mine in Quebec and advance the Moblan project to final investment decision. The three-stage NAL brownfield expansion, with capex of C$366 million, targets throughput increases lifting output to 338,000 t/y of spodumene concentrate and delivers a post-tax NPV of C$3.11 billion, 42% IRR and 25‑month payback. Proceeds will fund mill optimisation, flotation upgrades and crushing circuit enhancements, with Stage 1 starting mid‑2027 and Stage 3 construction due by mid‑2029.

Brazil’s antitrust authority Cade has opened a competition probe into USA Rare Earth’s proposed $2.8 billion acquisition of Serra Verde Group, operator of the Pela Ema rare earth mine and processing plant in Goiás, including a 15‑year US offtake agreement for neodymium, praseodymium, dysprosium and terbium. The review will determine whether the deal is a notifiable “concentration act” and could lead to approval, conditions or a full administrative case. Serra Verde, backed by a recent $565 million DFC funding package, expects Pela Ema to supply about half of ex‑China heavy rare earth output by 2027.

Copper futures in London jumped 2% on Tuesday, briefly breaching $14,000/t and moving back towards January’s $14,500/t record as Chinese inventories fall and state-owned traders signal strong decade-long demand. Satellite data from Earth-i show a sharp drop in global smelting activity in April and Sprott warns that disruptions to Middle Eastern sulphur supplies and fuel availability in Peru threaten output, with about 20% of mined copper dependent on sulphuric acid. Sprott projects data centres and energy-transition uses could take copper’s share of “strategic” demand to 45% by 2040, up from 32% in 2024.

Copper prices, already up 40% in 2025 and hitting a record $14,500/t in January 2026, are being driven by AI-related demand, supply disruptions and looming cost pressures from energy and sulfuric acid shortages, with the ICSG now forecasting a 150,000 t deficit for 2026. The 10 largest copper mines produced 4.9 Mt in 2025, led by Escondida at 1,347.6 kt, while major assets such as Grasberg and Kamoa-Kakula face landslide, flooding and seismic-related constraints that could remove hundreds of thousands of tonnes from the market. For planners and project developers, the rankings emphasise concentration risk in a handful of long-lived operations and the growing influence of infrastructure bottlenecks, community blockades and state renegotiations on effective supply.

First Quantum Minerals’ updated NI 43-101 for the La Granja copper project in northern Peru outlines 4.8 billion tonnes of measured and indicated resources at 0.48% Cu (23.0 Mt contained), plus 5.2 billion tonnes inferred at 0.40% Cu (20.7 Mt), based on 832 diamond holes totalling 370,000 metres. The company plans pit-side comminution and slurry transport via a 7 km tunnel to a processing and tailings complex on a flatter Pacific coastal plain ~100 km away, using desalinated seawater as primary supply. Engineering focus centres on managing arsenic as discrete, “packageable” mineral phases to maintain saleable concentrate through a conventional flowsheet under Peru’s strict ESIA regime.

The US Department of Energy has awarded contracts to exchange 53.3 million barrels of crude from the Strategic Petroleum Reserve’s Bayou Choctaw, Bryan Mound, Big Hill and West Hackberry salt cavern sites, as part of a 172-million-barrel commitment under the IEA’s coordinated release. The SPR currently holds about 384–397 million barrels, with 35 million barrels already delivered to market and an additional 35 million barrels generated for the reserve at no taxpayer cost through earlier exchanges. Under the new awards, DOE secures a 28% return premium—15.1 million barrels—and allows participating companies to use a limited Jones Act waiver to accelerate coastal shipments.

RCT – Powered by Epiroc has rapidly deployed its AutoNav Lite semi-automation package on two remotely operated dozers at a major gold mine in northern Canada to accelerate pit-wall stabilisation and remediation works in controlled zones. The system allows operators to run the dozers from a safe location outside exclusion areas while maintaining precise blade control for backfilling, bench shaping and push‑down tasks. For geotechnical and mine operations teams, this points to faster recovery of geotechnically constrained areas without exposing operators to rockfall or ground failure hazards.

BHP and Rio Tinto have formed a Tailings Management Consortium (TMC) and issued joint guidance focused on improving tailings dewatering and storage facility management. The collaboration targets higher degrees of dewatering to move operations away from conventional slurry dams towards safer, lower‑footprint options such as thickened, filtered or dry‑stacked tailings, in line with emerging global standards. Both miners state they will share operational learnings and design practices across industry, signalling more open benchmarking of tailings performance and risk controls.

Zijin Longking has dispatched the first production-line LK220E battery electric mining trucks from its Longyang City plant in Fujian Province, marking the start of series manufacture at the Longjing Smart Environmental Protection Industrial Park. At the same event on 9 May, the company signed a new contract for its larger LK350E battery electric truck, signalling customer commitment to higher-capacity BEV haulage. For mine planners and fleet engineers, this points to accelerating availability of Chinese-built battery trucks in the 220–350 t class for large open-pit operations.

Komatsu’s Mine 4D technology is being deployed at Boliden’s Kevitsa open-pit nickel-copper operation in northern Finland to give dispatchers and supervisors real-time visibility of fleets working in temperatures down to –40°C. The integrated platform links high-precision GNSS machine guidance, fleet management and production reporting so operators can track shovel–truck interactions, ore–waste boundaries and cycle times across 24/7 shifts. For engineers, the key gains are tighter compliance to dig lines, reduced rehandle and faster response to equipment or road condition issues in one of Europe’s harshest mining climates.

De Beers has recorded the lowest safety incident rate in its 135-year history, reporting a total recordable injury frequency rate (TRIFR) of 1.0 for 2025 across its global mining operations, improving on the previous year’s record low. The company attributes the performance to a strong “ownership” culture, with shared responsibility for risk controls and intensive frontline engagement in incident reporting and corrective actions. For geotechnical and mining teams, the figures signal that structured behavioural programmes and line-led safety leadership can materially reduce TRIFR even in high-risk, deep-level and open-pit environments.

Thames Water has awarded Barhale a £17M contract to deliver the final section of the Greenwich Trunk Main, a strategic potable water main serving Southeast London and intended to secure supply and improve network resilience. The remaining phase will connect existing trunk infrastructure to the wider distribution network through dense urban streets, requiring complex utility diversions, deep trenching in constrained corridors and careful management of traffic and third-party assets. For civil and geotechnical teams, key challenges will centre on maintaining service continuity, controlling ground movement around adjacent structures and managing high groundwater in London’s variable strata.

A UK Government research paper concludes that Nature-based Solutions such as floodplain reconnection, riparian woodland and leaky barriers are most effective when planned and modelled across whole catchments rather than as isolated site schemes. The study stresses integrating NbS with existing hard defences, using hydrological and hydraulic modelling to quantify peak flow attenuation and downstream level reductions under design storm events. For civil and drainage engineers, this points to earlier basin-scale option appraisal, multi-landowner agreements and long-term monitoring of storage volumes, infiltration rates and sediment behaviour.
