The Environment Agency has submitted a planning application for the Portreath Flood Alleviation Scheme in Cornwall, centred on safeguarding a 95-year-old coastal tunnel that currently conveys storm flows through the village. The scheme is described as a major capital investment to protect homes, businesses and community facilities from coastal and fluvial flooding, following repeated storm damage to Portreath’s seafront infrastructure in recent winters. For geotechnical and civil teams, key issues will include assessing the existing tunnel’s structural condition, lining options and hydraulic capacity under future climate-driven peak flows.

A trackside fire reported and extinguished on Sunday 27 September near Clapham Junction has severely damaged signalling equipment, forcing an “extremely reduced train service” to and from London Victoria until at least 14:00 today. Network Rail signalling and permanent way teams worked overnight to reinstate key interlocking and lineside control circuits to keep a limited number of routes open through one of Europe’s busiest junctions. The incident exposes the vulnerability of legacy lineside signalling assets to localised fire and heat damage, with knock-on impacts on timetable resilience and maintenance planning.

VolkerRail has completed a month-long programme to renew more than 750m of embedded track on the Croydon central tram loop on the London Trams network. Works focused on replacing street-running rail sections set in concrete, requiring staged possessions and traffic management through Croydon town centre to maintain tram and road access. The scheme will be relevant for engineers dealing with embedded grooved rail, slab track detailing, and managing construction interfaces with urban utilities and streetscape.

Closed-door government briefings will be given to chief executives of UK critical national infrastructure operators on what security agencies describe as an elevated Russian threat, including potential cyber and hybrid attacks on energy, water, transport and communications networks. CNI leaders are expected to review physical protection of key assets such as substations, control rooms and data centres, alongside resilience of industrial control systems and SCADA networks. For civil and infrastructure engineers, this signals likely tightening of design, access control and redundancy requirements on new and existing strategic assets.

Neso issued an electricity margin notice (EMN) for the GB grid on 28 September, signalling that forecast supply was close to demand and inviting additional generation onto the system, before cancelling the notice later in the day as conditions eased. EMNs are a formal tool within the Balancing Mechanism, used when operating margins fall below Neso’s predefined security thresholds but before any controlled disconnections are considered. Grid planners, interconnector operators and flexible generators will note the tightness in capacity margins as an operational stress test ahead of peak winter demand.

The Institution of Engineering and Technology has launched the 2026–27 IET Faraday Challenge with a new flexible format allowing schools, youth groups and home-educating families to run engineering design challenges on their own timetable rather than fixed competition days. Teams of 6–8 students aged 12–13 will work on a real-world brief from an industry partner, using standardised kits of electronic components and structural materials supplied by the IET. The format is intended to widen access beyond well-resourced schools and give more pupils early exposure to structured engineering problem-solving.

MPs on the Public Administration and Constitutional Affairs Committee have opened an inquiry into how effectively the UK state delivers major infrastructure, with a focus on procurement models and governance. The review will examine how current contracting approaches, such as design-and-build and alliancing, affect cost overruns, programme slippage and risk transfer on large schemes like HS2 and major road upgrades. Outcomes could influence future Treasury Green Book guidance, Cabinet Office procurement rules and how client bodies structure frameworks and long-term delivery partnerships.

Morocco’s first large-scale lithium iron phosphate battery energy storage system has been energised at OCP Green Energy’s Benguerir phosphate mine, with Envision Energy supplying and commissioning a 25 MW/125 MWh installation under a contract signed in late 2025. The system’s five-hour storage duration enables significant load shifting for mine power demand, supporting higher penetration of on-site renewables and reducing reliance on grid or diesel peaking. For mine planners and electrical engineers, this provides a full-scale reference for integrating LFP BESS into large, continuous-process operations in North Africa.

Northern Star Resources has rejected Gold Fields’ unsolicited A$38.7 billion (about A$27 per share) takeover proposal, calling the largely scrip-based offer (73% in new Gold Fields shares) “highly opportunistic” and undervaluing what chair Michael Chaney terms “one of the world’s premier gold portfolios”. A merger would create the world’s second-largest gold producer after Newmont, with about 2.4 Moz/year of Australian output and six of Australia’s 15 largest gold mines, but would shift Northern Star investors into South African jurisdictional and operational risk. Gold Fields claims up to $5 billion in synergies and at least $4 billion in asset sales, while activist Elliott presses Northern Star’s board to engage.

Hudbay Minerals has lifted life-of-mine gold output at its Snow Lake operations in Manitoba by about 60% to 2.8 million oz, extending mine life to 2043 and targeting average production of 185,000 oz per year from 2026–2030. The uplift is driven by higher mining rates, better mill utilisation and improved recoveries, with New Britannia running above 2,000 t/d and planned to reach 2,300 t/d by 2027, still below its 2,500 t/d permitted capacity. Forecast cash costs average $821/oz and sustaining cash costs $1,379/oz over 2026–2030, with Jefferies flagging a sharp step-up to about 126,000 oz/y from 2031–2035 versus its prior 32,000 oz/y estimate.

Peninsula Energy’s Lance uranium project in northeast Wyoming has increased contained resources to 59 million lb. U3O8, including 15.5 million measured and indicated tonnes at 0.05% U3O8 and 38.5 million inferred tonnes at 0.04% U3O8, with the producing Ross area up nearly 16% to 7.4 million lb. Despite this, Peninsula has withdrawn its 2026 production guidance of 400,000–500,000 lb. U3O8 after low solution flow rates in ISR wellfields and has booked a US$50-million non-cash impairment on Units 1–3. The key technical risk now centres on whether the main Unit 4 at Ross can achieve design flow rates and head grades to support the maintained 2027 target of 500,000–600,000 lb. U3O8 and future development of the larger Kendrick and Barber areas.

Montage Gold has poured first gold at the Koné mine in Côte d’Ivoire on 26 September, months ahead of its original Q2 2027 target, after processing over 400,000 tonnes of ore through the oxide circuit to produce about 1,140 oz. The oxide circuit is expected to reach commercial production by year-end, with a hard-rock comminution circuit due mid-2027, supporting a planned 16-year mine life and output of more than 300,000 oz per year over the first eight years. Koné now hosts 6.29 Moz measured and indicated at 0.80 g/t Au and 2.03 Moz inferred at 0.68 g/t Au, following 380,000 metres of drilling since the 2024 feasibility study.

US-backed moves to build a Brazilian critical minerals chain are accelerating, with American investment already above $600 million and a non-binding agreement in Goiás covering rare earth mining, separation, metal alloys and permanent magnets. USA Rare Earth’s $2.8‑billion acquisition of the Serra Verde operation, producing mixed rare earth carbonate at Pela Ema, and St George Mining’s study of a 2‑billion‑real processing and separation centre in Minas Gerais signal concrete downstream ambitions. New Brazilian legislation creates a National Council for the Industrialisation of Critical and Strategic Minerals and offers tax credits of up to 20% for processing and urban-mining spend from 2030–2034, tightening state oversight of strategic assets.

B2Gold has defined a new high-grade Tattuk zone at the Goose mine in Nunavut, with drillhole 26GSE750Z2 cutting 9.95 m at 10.94 g/t gold from ~1,196 m depth, 150 m down-plunge of existing Nuvuyak mineralisation, alongside infill hits of 21.23 m at 19.12 g/t at Llama and 6.9 m at 11.88 g/t at Nuvuyak. Following an April crusher fire, a new mobile plant commissioned in August is averaging >3,000 t/d, while a repaired fixed circuit with new ROM bin, apron feeder, larger jaw crusher and rock breaker is targeted to sustain 3,200 t/d from October. B2Gold is holding 2026 Goose guidance at 170,000–200,000 oz, budgeting $51 million for Back River exploration and planning stage-two upgrades to reach the 4,000 t/d design rate and extend the current ~nine-year reserve-based mine life.

Washington’s escalating trade disputes with Ottawa risk undermining its strategy to cut dependence on Chinese minerals, with CFR senior fellow and former US sanctions official Edward Fishman warning that the United States “cannot do it without the Canadians”. China currently controls about 91% of global refined rare earth magnet output and has already used export controls to disrupt automotive production, while US-aligned supply is emerging through projects such as Centerra Gold’s US$425–450 million restart of the Thompson Creek molybdenum mine feeding the Langeloth plant. Hecla Mining is doubling down on lower-risk jurisdictions with silver production from Greens Creek (Alaska), Lucky Friday (Idaho) and Keno Hill (Yukon), betting that jurisdictional stability will support premium valuations as supply chains fragment.

US Department of War funding of $9.25 million into Strategic Minerals’ Cornwall Resources unit will push the Redmoor tungsten-copper-tin project in Cornwall through definitive feasibility within a targeted 32 months, supporting extensive infill and expansion drilling, geotechnical and metallurgical drilling, and updated Mineral Resource Estimates and reserve conversion. The non-dilutive funding, with no restrictions on future offtakes, is aimed at fast-tracking underground mine development at what is described as Europe’s highest-grade undeveloped tungsten resource. Strategic Minerals’ shares rose 14% in London, giving the company a £168.6 million market capitalisation.

EACON Mining Technology has validated an autonomous haulage capability at Zijinshan copper-gold mine that keeps trucks running driverless through extended tunnel sections where GNSS/RTK positioning and network connectivity drop out. The system uses on-board perception and localisation to operate without full dependence on conventional high-definition maps, targeting long underground or covered haul segments rather than short blind spots. For mine planners and automation teams, this points to AHS designs that can tolerate sustained signal loss in complex pit–portal–tunnel layouts.

Sandvik will supply a 27-unit underground fleet to Orken LLP, the iron ore division of Qarmet JSC, to mechanise development at the Atasu operation in the Western Karazhal mine, Kazakhstan. The package includes 13 Toro TH430 trucks and five Toro LH410 loaders, shifting the mine from manual development headings to fully mechanised haulage and loading. The move signals higher development advance rates and more consistent ground support installation, with implications for ventilation design, traffic management and maintenance planning in existing drifts.

ARMD Australia has launched the R800 Footbridge system, a modular temporary works solution designed to span roads, railways and waterways while keeping traffic and rail operations running during construction. The steel system is supplied in pre-engineered modules for rapid assembly and crane placement, allowing contractors to install pedestrian access over live corridors without full closures or extensive foundations. For temporary works planners, the key shift is a standardised, reusable bridge package that can be redeployed across multiple sites instead of bespoke scaffold or one-off fabricated structures.

A $319 million contract has been awarded by Armidale Regional Council for the reconstruction of Kempsey–Armidale Road, the largest Essential Public Asset Restoration project yet undertaken in New South Wales. Works will focus on the Big Hill to Blackbird Flat section, where multiple landslips and slope failures have severely damaged the mountain road corridor. Geotechnical design and construction will centre on stabilising slip-prone cuttings and embankments, rebuilding pavement and drainage, and restoring reliable heavy-vehicle access between the coast and Northern Tablelands.

Cottsway Housing Association has renewed its materials supply contract with Travis Perkins Managed Services for a further seven years to 2033, covering repairs and maintenance across more than 7,000 homes in West Oxfordshire, Gloucestershire, Wiltshire and Worcestershire. Materials will continue to be supplied via a dedicated TPMS branch in Witney, a standalone facility staffed by five full-time colleagues serving Cottsway exclusively, supporting predictable lead times and stock control for routine works. Cottsway will also expand use of the TPgo Digital Suite, adopting the TPgo Order app so trades operatives can order, track and collect materials directly.

Arada has lodged its first planning applications for Thameside West with Newham Council, covering 1,500 homes in six dockside buildings as part of a £2.5bn scheme targeting at least 5,000 units on the Royal Docks brownfield site. The initial two buildings are proposed as 100% social rent, including three- and four-bedroom family units, with permeability prioritised through a network of streets, gardens, parks and shared public spaces. Ground-floor frontages to the new park are planned for cafés and restaurants, with Gensler, Arup and Planit shaping architecture, engineering and landscape design.

Huws Gray has added plant and tool hire to its Fleetwood, Lancashire branch, making it the 87th depot in its UK network to offer hire services alongside existing builders’ merchant operations. Contractors can now source excavators, compact plant and branded tools, plus repair and servicing, on a single Huws Gray account rather than using separate local hire firms. The expansion has created three new roles on the 18-strong site and targets a known shortage of tool hire options in the Fleetwood area.

Aston University is partnering with Jesmonite Ltd under an Innovate UK knowledge transfer partnership to redevelop Jesmonite’s low‑carbon acrylic, resin-based composites with added biochar as potential cement alternatives for façades and surface applications. Researchers from Aston’s Energy and Bioproducts Research Institute and Department of Civil Engineering will characterise the materials at molecular level and test mechanical and durability performance while targeting further reductions in embodied carbon. The work aims to move Jesmonite’s currently niche, film-set and design products into mainstream construction specifications, offering designers non‑cementitious façade and cladding options.
