National Grid is replacing overhead conductors on a 40km, 400kV transmission route between Mannington substation in East Dorset and Nursling substation in Southampton, with Balfour Beatty appointed as principal contractor. The works cover 115 lattice steel pylons and will require sequential wire replacement while maintaining network security on this key south coast corridor. Contractors will need to manage live-line safety constraints, temporary outages and access logistics along a mixed rural–urban alignment.

Esh Construction has secured a £3.1M contract from Rotherham Metropolitan Borough Council to deliver a flood alleviation scheme for the repeatedly flooded village of Whiston. Works are expected to focus on new and upgraded flood defences and drainage infrastructure along key flow paths, targeting a recurrence of the severe recent flood events. Geotechnical and civil design will need to address surcharge of existing culverts, overland flow routing and integration with the wider Rotherham flood risk management network.

Sean Carr Lining Technology has completed construction of a lined storage lagoon for underground water from planned lithium exploration in Cornwall, a key enabling asset while the project awaits its Final Investment Decision. The lagoon is designed to hold pumped mine water prior to processing, allowing controlled management of flow rates and water quality during test and early-stage extraction. For geotechnical and civil teams, the milestone fixes the site’s hydraulic management concept and de-risks subsequent drilling, treatment plant foundations and environmental permitting.

A lineside fire near Rustington in West Sussex forced the suspension of all Southern Railway services between Worthing and Littlehampton/Barnham, with Network Rail classing the incident as “major disruption”. Engineers were deployed to inspect and repair affected track, signalling cables and associated lineside equipment before services could be safely restored. The event underlines the vulnerability of coastal commuter corridors to relatively small infrastructure faults, with knock-on impacts for timetable resilience and maintenance planning.

A 750t all-terrain mobile crane has installed the nine prefabricated sections forming the staircases and bridge deck for the new footbridge at Bristol Brabazon station on the former Filton Airfield site over the Bank Holiday weekend. The modular lift sequence minimised disruption to adjacent rail infrastructure and surrounding development works, with all major elements placed within a short possession window. For contractors and designers, the operation reinforces the viability of heavy prefabricated bridge components and rapid craned installation on constrained brownfield transport hubs.

New drilling at Group Eleven Resources’ PG West project in Ireland has extended high-grade mineralisation at the Ballywire discovery, with hole 26-3552-57 cutting 62.5 m from 329 m depth grading 2.9% Zn, 2.7% Pb and 25 g/t Ag, including 11.8 m at 3.3% Zn, 10.1% Pb and 45 g/t Ag. Backed by C$12 million raised in March from investors including Glencore (13% stake) and Michael Gentile (14%), the company has expanded its PG West drilling campaign from 20,000 m to 67,000–75,000 m using four rigs. Mineralisation comprises sphalerite, galena and pyrite with local chalcopyrite and suspected tennantite-tetrahedrite, now traced along a ~1.5 km massive sulphide corridor.

America’s rapid “mineral awakening”, argued by Brian Paes‑Braga, CEO of The Metals Royalty Company (Nasdaq: TMCR), is driven by dependence on foreign processing, with China now handling roughly 70% of global energy‑related critical minerals and 98% of primary gallium. The US was fully import‑dependent for 16 non‑fuel minerals in 2025, while an F‑35 needs about 900 lb of rare earths and a hyperscale AI data centre can require up to 50,000 tonnes of copper, exposing defence and grid resilience to external chokepoints.

Petra Diamonds is placing its Finsch mine in South Africa into business rescue, suspending capital development and starting consultations on workforce reductions across operations as realised prices slump to about $47/ct at Finsch and $81/ct at Cullinan, down from $56/ct and $109/ct in Q3. Management cites a structural decline in prices for smaller stones (Finsch mainly produces ≤2 ct goods and contributed 34% of FY2025 revenue), growing lab-grown competition and a strong rand, and has withdrawn 2026–2030 production guidance while it reworks its plan around high-value Type II output at Cullinan. The company has secured lender consent to avoid covenant defaults but warned of possible liquidity breaches later in 2026, with Petra’s market capitalisation now about £42 million after the share price fell 17% to 11p.

Rio Tinto has begun a $1.5 billion expansion of its AP60 low‑carbon aluminium smelter at Arvida, Quebec, adding 96 new AP60 pots to lift capacity to about 220,000 tonnes per year, a 160,000‑tonne increase. Powered by hydroelectricity, the AP60 process emits about one‑seventh of the global industry average and is expected to cut Rio’s carbon emissions by roughly 290,000 tonnes per year as older Arvida potlines are phased out by next month. The project, backed by up to $113 million from Quebec, has created more than 1,500 construction jobs and will employ about 100 permanent staff, with a nearby recycling facility planned to integrate post‑consumer aluminium.

Military Metals’ share price fell as much as 60% to C$0.16 after Slovakia’s Ministry of the Environment revoked its exploration licence for the Trojarova antimony-gold project near Bratislava, which the company says was cancelled “without appropriate justification”. Trojarova, interpreted as a continuation of the historic Pezinok mine, carries a Soviet-era resource of 415,000 tonnes grading 0.162% Sb and 1.148 g/t Au based on underground exploration. The licence had been within Slovakia’s designated exploration areas under the EU critical raw materials framework, raising questions over regulatory risk for antimony supply projects in the region.

Deep Sea Minerals (CSE: SEAS) has applied to uplist to the Nasdaq, which would make it the third seabed exploration company on the exchange alongside The Metals Company (Nasdaq: TMC) and Odyssey Marine Exploration (Nasdaq: OMEX), pushing its share price to a record C$1.79 and valuing it at just over C$80 million. The Vancouver-based firm currently has no active projects but is targeting polymetallic nodule concessions in the 4.5‑million‑sq‑km Clarion–Clipperton Zone (3,500–6,000 m water depth) and the Cook Islands EEZ, where nodules are estimated at 21 billion tonnes and 6.7 billion tonnes respectively. For mining strategists, the move signals another capital-markets vehicle positioning early for potential future access to large-scale subsea nickel, cobalt, copper and manganese resources pending regulatory pathways in the Pacific.

US efforts to revive primary aluminium hinge on securing long-term, industrial-scale power contracts of 500+ MW per smelter, with advocates warning that data centres and hyperscalers are outbidding producers for grid capacity. Imports of Canadian primary aluminium fell from 2,745 kt in 2024 to 1,950 kt in 2025 after Section 232 tariffs rose to 50%, even as Century Aluminum and Emirates Global Aluminium plan the first new US smelter since 1980 in Oklahoma, still stalled pending a power deal. Rio Tinto’s $1.5 billion AP60 low-carbon smelter expansion in Quebec and EU CBAM-driven demand are meanwhile pulling more Canadian hydropower-based metal towards Europe, risking longer-term diversion of supply away from the US.

Pulsar Helium has bought 1,360 acres of surface land at its 100%-owned Topaz project in Lake County, Minnesota, from Wolf Lands Inc. for $2.48 million, securing the JS#7 (Jetstream #7) well site and other key infrastructure locations directly above its leased mineral rights. The company now controls surface access over the core discovery area as it tenders for up to four new production wells to complement two production-ready wells, supported by newly enacted Minnesota helium-specific permitting legislation signed on 26 May.

Edinburgh’s Gold Copper Diamide Extraction (GCDE) process has been exclusively licensed to Lithium Universe, enabling low‑temperature hydrometallurgical recovery of gold and copper from e‑waste using small, reusable organic ligands instead of >1,200°C smelting or cyanide and mercury leaching. The diamide “molecular magnet” first targets gold, followed by a selective copper step, delivering high‑purity metals from printed circuit boards where gold and copper content can exceed US$48,000 per tonne at current prices. Lithium Universe will integrate GCDE into its Precious Metals Recycling Division and sub‑licence the technology globally.

Evonik has formed a strategic partnership with the School of Mining at the University of Guanajuato in Mexico to develop next‑generation sustainable, lower‑toxicity reagents for mineral processing. The collaboration centres on Evonik’s biosurfactant platform, targeting replacement of conventional petrochemical surfactants in flotation and related unit operations to cut ecotoxicity and improve biodegradability. For mine operators, this points to future options for meeting stricter water‑quality and tailings‑discharge limits without major flowsheet changes.

Tharisa Minerals has deployed an advanced adaptive wireless network across its South African open-pit mine in partnership with hybrid ICT integrator Datacentrix, creating what it calls a highly connected, data-driven operation. The Africa-first solution replaces legacy, patchy communications with a mine-wide, high-bandwidth wireless backbone designed to support real-time fleet telemetry, high-resolution condition monitoring and IP-based voice and video. For geotechnical and mining engineers, the infrastructure enables faster dispatch decisions, tighter drill-and-blast control and more reliable data capture from mobile equipment and in-pit monitoring systems.

Metso has inaugurated an expanded Service Centre and a new Training Centre in Mesa, Arizona, combining OEM‑level maintenance for crushers, mills and screens with a purpose‑built classroom and hands‑on training facility in a single site. The Mesa hub is positioned to support large copper and gold operations across the US Southwest, reducing overhaul lead times by keeping critical component repairs and rebuilds closer to mine sites. Co‑located training on Metso equipment and digital tools should help standardise maintenance procedures and improve asset availability for regional fleets.

Sandvik Mining has secured ISO/IEC 27001 certification for its global IT application delivery after an independent external audit of its Information Security Management System. The accreditation covers mission‑critical digital business capabilities supporting mining operations, including protection of operational data, system availability and integrity for fleet management, automation and remote monitoring platforms. For mine operators relying on Sandvik’s connected equipment and cloud‑hosted services, the certification provides a defined, audited framework for risk management, access control and incident response in line with the leading international information security standard.

Queensland’s 2032 Olympic and Paralympic Games programme is driving an unprecedented transport and civil works pipeline, with RoadAid Director and Founder Chris Couldrey warning that concurrent megaprojects will strain labour, plant availability and traffic management capacity. Couldrey points to tightly sequenced upgrades on key motorway corridors and urban arterials, plus complex staging around live networks, as critical risks for cost escalation and schedule slippage. He argues that standardised workzone designs, stronger subcontractor prequalification and earlier utility coordination could leave a lasting uplift in project delivery capability beyond 2032.

Works on Melbourne Airport Rail Stage One are advancing, with site investigations now under way in Tottenham for the West Footscray to Albion Rail Upgrade. The first stage will untangle approximately six kilometres of existing track between West Footscray and Albion and construct two new platforms at Sunshine Station, a key junction for regional and metropolitan services. Track reconfiguration and additional platform capacity will be central to future airport rail operations planning, signalling design, and construction staging around live rail corridors.

Georgiou Group is using the New Midland Station project in Western Australia as a training ground for emerging engineers and supervisors while delivering a major rail and precinct upgrade. The contractor is integrating station construction with live rail operations and surrounding road interfaces, requiring tight staging, complex traffic management and coordination with existing utilities. Structured mentoring and on-the-job exposure to brownfield constraints, rail safety protocols and multidisciplinary interfaces are intended to build capability for future large-scale transport infrastructure pipelines.

Design for the $250 million Curtis Road Level Crossing Removal in Adelaide has been released, targeting a bottleneck where about 21,000 vehicles cross daily and boom gates are down up to 15 minutes each peak hour. The concept aims to separate road and rail at this high‑delay interface, with layout and structural options now open to community feedback during May. For designers and contractors, key issues will include maintaining traffic flow during construction staging and managing rail possessions on this busy corridor.

Brightstar Resources has intersected multiple zones of visible gold in deep diamond drilling at the Two Mile Hill deposit, strengthening the case for underground development at its Sandstone gold project in Western Australia. The adjacent Two Mile Hill–Shillington system hosts a combined JORC mineral resource of 753,000 ounces at 1.5 grams per tonne gold, with the new intersections extending mineralisation at depth. Results point to potential for higher-grade underground stopes beneath the current open-pit shells, which could materially change mine design and scheduling.

China’s April 2025 export licensing rules on several medium and heavy rare earth categories immediately disrupted supply to defence, energy and automotive manufacturers, with buyers scrambling for non‑Chinese oxides, metals and magnets. The later delay of a second control round has given Australian and US developers a short window to advance mine, concentrator and separation projects, including hydrometallurgical plants capable of producing NdPr, Dy and Tb products to specification. Engineers are now prioritising logistics corridors, power and reagent supply, and waste and tailings infrastructure sized for multi‑decade rare earth operations.
