Tunnel excavation has been completed by Murphy on a major sewer upgrade in Eccles, Greater Manchester, forming the core of a new larger-diameter tunnelled sewer designed to cut local flood risk. The drive, constructed using trenchless methods beneath existing urban infrastructure, replaces an undersized legacy asset that has been prone to surcharge during intense rainfall. Completion of tunnelling now allows connection of lateral sewers and installation of new manholes and chambers, a critical stage before commissioning the increased-capacity network.

Commonwealth Fusion Systems has released five peer‑reviewed papers claiming to validate the plasma confinement and stability physics underpinning its compact, high‑field Arc fusion power plant concept. Arc is based on high‑temperature superconducting magnets to generate stronger magnetic fields in a smaller tokamak, targeting grid‑scale output in a footprint closer to a conventional thermal plant. For civil and infrastructure engineers, this supports planning for dense, urban‑adjacent fusion sites with nuclear‑grade containment structures but reduced land‑take compared with large fission stations.

Fortune Minerals plans to release an updated feasibility study next month for its Nico cobalt-gold-bismuth-copper project in Tłı̨chǫ territory, targeting 2027 construction on a 20-year mine producing about 8,780 t/y cobalt sulphate, 47,000 oz/y gold, 1,700 t/y bismuth products and 500 t/y copper cement. The 33.1 Mt reserve (0.11% Co, 1.03 g/t Au, 0.14% Bi, 0.04% Cu) previously carried a C$589 million capex, now estimated by the company at roughly C$1 billion, with concentrate trucked 400 km to rail at Enterprise then 1,000 km to an Alberta hydromet plant. Fortune has secured over C$17.5 million in non-dilutive funding, applied for up to $50 million for a 50-km spur road, and is leveraging bismuth supply risk after China’s export curbs pushed prices from about $7/lb to above $20/lb.

Bolivian President Rodrigo Paz’s proposed “state of exception” law, following Law 1732 and 36 days of nationwide protests with more than 90 road blockades across eight regions, injects fresh political and security risk into development of the Salar de Uyuni and other world-class lithium resources. Expanded military powers to clear transport corridors for food, fuel and medical supplies raise the prospect of violent confrontation with peasant organisations, labour unions and the Bolivian Workers’ Union. For lithium developers, OEMs and battery makers, the standoff threatens timelines and investment appetite in one of the largest yet least-developed brine provinces.

Botswana is courting sovereign wealth funding from the UAE and Oman to help buy a controlling stake in De Beers as Anglo American advances the sale of its 85% holding, having written the business down to $2.3 billion. President Duma Boko has also opened talks with Namibia and Angola, leveraging Botswana’s existing 15% De Beers stake and pre-emptive rights over Anglo’s shares. With diamonds providing about 80% of exports and roughly 25% of GDP, the move responds to price weakness, Chinese demand slowdown, lab-grown competition and a recent S&P credit downgrade.

Silver demand is set to outstrip supply for a sixth straight year, with the Silver Institute’s World Silver Survey 2026 projecting a 46.3-million oz. deficit after prices briefly spiked above US$120/oz in January from US$30/oz a year earlier. Photovoltaic silver use fell 6% in 2025 to 186.6 million oz. and is forecast to drop a further 19% to about 151 million oz. in 2026 as manufacturers adopt TOPCon cells, zero-busbar layouts and ultra-fine printing to push loadings below 5 mg/W by 2027. Analysts warn that even 10–20% thrifting and potential copper substitution cannot fully offset demand from solar, grid expansion, automotive and AI-driven power loads, so miners should plan around structurally tight silver markets rather than a simple linear link to installed PV capacity.

Tungsten producer Almonty Industries is issuing US$700 million of 2.25% senior convertible notes, convertible at US$27.40 per share with a capped call at US$41.36, to fund about US$543 million of working capital plus US$50 million of debt refinancing, causing an 18% share price drop to roughly US$17.20. The notes, offered to qualified institutional buyers and settling on 9 June 2026, include an option for a further US$100 million. Funding supports ramp-up at the Sangdong mine in South Korea, where a 640,000 t/y plant targets 2,300 t/y tungsten concentrate, with Phase 2 aiming for 1.2 Mt/y and 4,600 t/y output.

Central banks returned to net gold buying in April, adding 17 tonnes to reserves after March’s net sales, with bullion trading near record highs at about $4,390/oz, according to the World Gold Council. Poland and China led purchases with 14 tonnes and 8 tonnes respectively, while the Czech Republic added 3 tonnes in its 38th consecutive monthly buy and Russia and Uzbekistan sold 6 tonnes and 1 tonne. Emerging-market banks in Eastern Europe and Asia have averaged 29 tonnes of net monthly purchases over the past three years, signalling persistent official-sector demand for mined gold.

Gold fell as much as 3.5% to $4,315/oz, its lowest since March, erasing 2026 gains after a strong US May nonfarm payrolls print pushed Treasury yields and the dollar higher and lifted Fed rate hike odds. US gold futures dropped over 3.2% to $4,342/oz, with CME FedWatch now pricing about a 68% chance of a December hike versus roughly 50% pre-data. Since the Iran war began and the Strait of Hormuz closure drove energy prices up, bullion has slid nearly 18%, raising the cost of carry for non-yielding gold.

US Ambassador Pete Hoekstra is urging Canada to act as a core US partner on critical minerals, energy and defence, framing a North American “economic fortress” built on Canadian resource endowment and mining expertise, including experience working with Indigenous communities. He cited existing integration such as 3–4 million barrels of oil per day moving from Alberta to the US, growing Quebec–US power interconnections, and Davie Shipbuilding’s expansion into Finland and Texas as models for cross-border industrial projects. Hoekstra warned that Washington is already backing billions of dollars in critical minerals deals with allies like Australia and “is not waiting” if Ottawa hesitates to join US-led frameworks.

Calgary-based Litus has signed a 25 May memorandum of understanding with Taiwan’s UWin Nanotech to jointly develop selective extraction, separation, recovery and purification flowsheets for cobalt, lithium, nickel and other elements from battery recycling and other secondary sources. The collaboration will combine Litus’ LiNC one-step direct lithium extraction platform for low- and high-concentration brines and its ReLiGN battery recycling process with UWin’s hydrometallurgical systems used in Apple-certified e‑waste and Li-ion recycling. Engineers should watch for integrated nanomaterial–hydromet circuits targeting both critical minerals and rare earth elements in circular supply chains.

MMD used The Electric Mine 2026 conference in Lisbon to detail its acquisition of global rights to an intelligent material handling system designed to integrate in-pit crushing, conveying and truck haulage. The company is positioning the technology for fully mobile and semi-mobile IPCC layouts, targeting higher throughput and lower energy use than conventional truck-only haulage, particularly in deep open pits. For mine planners and geotechnical teams, the approach implies earlier commitment to fixed crusher locations, re-profiled ramp geometries and tighter control of bench stability around conveyor corridors.

PLS has commissioned Australia’s first mine-site lithium mid-stream processing facility at its Pilgangoora Operation in Western Australia, with Premier Roger Cook officiating the opening, marking a shift from exporting raw spodumene concentrate towards higher-value battery materials. The Mid-Stream Demonstration Plant is integrated directly with the existing open-pit and concentrator complex, enabling on-site conversion steps that are normally performed at distant chemical refineries. For mine planners and process engineers, this signals growing interest in co-locating beneficiation and mid-stream refining to cut logistics, reduce intermediate handling and tighten quality control.

Boton is deepening conveyor technology collaboration with BHP and Hancock Iron Ore, hosting senior delegations at its Wuxi headquarters to review performance of its high-wear belt materials and advanced splice designs on large iron ore overland systems. Discussions reportedly centred on extending belt life in abrasive Pilbara ores, optimising idler spacing and troughing angles for higher tonne-per-hour capacities, and integrating condition monitoring for early detection of misalignment and shell wear. For mine operators, the work signals continued incremental gains in conveyor availability and reduced maintenance shutdown frequency on long-haul ore routes.

Weichai-controlled LOVOL Heavy Industry has delivered its first FR2000F hydraulic mining excavator, a 212 t class machine, to an open-pit mine customer in China. The FR2000F is powered by a Weichai 12M33 low-speed, high-torque, fully electronically controlled engine with quad-turbocharging and an advanced modular design, aimed at high-load, continuous mining duty. The 200 t class size positions it for pairing with ultra-class haul trucks, potentially altering fleet configurations and loading cycle times on large benches.

Knights Brown has reported 2025 turnover of £136m, up from £116m, with a gross margin of £15m and EBITA of £5.4m, equivalent to a 4% margin. The civils and construction contractor is active in coastal defence, port infrastructure and energy schemes, signalling a workload mix weighted to heavy civil engineering rather than building. Management is now positioning for AMP8 water-sector frameworks, where long-duration, programme-based contracts could materially influence future cashflow stability and resource planning for marine, pipeline and treatment-plant works.

MKM Building Supplies chief operating officer Dave Castle has been appointed board adviser to the Builders Merchants Federation, returning to the BMF Board as MKM expands its UK branch network. Castle, MKM’s first-ever COO with over 21 years’ experience in the building materials sector, has been working directly with branch directors, suppliers and customers to support ongoing investment in branches, people and services. His role at BMF will focus on training, safety, government lobbying and promoting careers in merchanting, giving MKM direct input into industry-wide policy discussions.

Base Concrete in Hemel Hempstead has purchased a second JCB TM420 telescopic wheel loader from Greenshields JCB to handle sand, cement and aggregate loading for its mobile batching lorry fleet. The TM420’s bucket capacity and boom extension were selected to match truck dimensions and cycle times in a constrained yard, avoiding both oversize machines that cannot manoeuvre and undersize units needing multiple passes. Director Paul MacGregor cites the balance of loading speed, bucket size and manoeuvrability as critical for reliable on-site concrete production.

Alliance Tool Hire has invested £900,000 in more than 20 new delivery vehicles, adding 3.5‑tonne Ford Transit 350 Leader L4 dropside vans and smaller Transit L3 models to support operations from its 10 UK depots. The Poole-headquartered firm services sites from Bath, Bristol, Salisbury, Poole, London (north, south and east), Kent, Gatwick and Newport, supplying power tools, access and survey equipment, and lifting hire and sales. Increased dropside capacity and mixed vehicle sizes should improve tool and small plant logistics to congested urban and regional infrastructure projects.

Turner & Townsend has reported 2025 global gross revenue of £5.76bn, a workforce of 22,000 and a real estate major-projects portfolio approaching £3tn in capital investment, including the UK New Hospital Programme and Barclays’ New York headquarters. Infrastructure growth is being driven by Heathrow Airport expansion, Anglian Water’s long‑term capital investment programme and the Clyde 2070 defence programme, plus new airport commissions in Vietnam, Bangalore and Perth. In energy and natural resources, the firm has been appointed a critical partner on Rolls‑Royce’s nuclear programme, extending its nuclear work across six continents.

CITB has launched an Accelerated Apprenticeships programme targeting 1,680 starts over four years to support the government’s 1.5m homes by 2029, cutting typical training duration from 2–3 years to 14–18 months for bricklaying, carpentry and roofing. Delivery uses intensive front‑loaded learning plus structured block release and on-site experience through an initial five programmes at FE colleges and training providers, expanding to 20 by mid‑2029. The first phase prioritises Greater Manchester, West Yorkshire, West Midlands, Kent, and Bedfordshire/Hertfordshire, feeding into a new National Construction Mayoral Network.

DB Cargo UK has invested £8.5m, financed via a Siemens Financial Services credit line, to purchase seven Liebherr LH 40 material handlers for its rail-served aggregate terminals. The diesel-electric LH 40 units will load construction aggregates onto freight trains, supporting higher throughputs and shifting material from road to rail. For civil and rail engineers, the move signals continued build-out of dedicated aggregate handling capacity to back large UK infrastructure and housing projects with lower-carbon logistics.

BULK2026 in Melbourne will focus on protecting productivity, safety and material integrity across the bulk handling chain, from flow control equipment to large-scale storage such as silos, stockpiles and export terminals. Technical sessions are expected to cover dust and spillage control, belt conveyor reliability, chute design, and condition monitoring for increasingly long, high-capacity conveyor systems. For mining engineers, the event signals growing emphasis on managing fire, explosion and structural risks in larger, more complex bulk handling plants rather than just maximising throughput.

Fresh international demand, tightening energy markets and rapid data centre expansion are giving Australia’s thermal and metallurgical coal sector renewed momentum, with India emerging as a key growth market. Energy security concerns in Asia are supporting long-term offtake for high‑CV thermal coal from Queensland and New South Wales, while steel demand keeps coking coal exports competitive against alternative suppliers. For mine planners and infrastructure owners, the signals point to sustained port throughput, rail capacity utilisation and potential brownfield mine life extensions rather than rapid phase‑out.
