OceanaGold is weighing a 50% expansion of its Waihi plant to 1.2 Mt/y after Wharekirauponga drilling returned standout intercepts including 6.3 m at 97.2 g/t Au from 481.5 m in the East Graben vein and 8.5 m at 41.5 g/t from 399 m. The move would enable concurrent feed from Martha Underground and Wharekirauponga post‑2032, building on a 2024 plan outlining 1.6 Moz over 15 years and an initial 4.1 Mt reserve at 9.2 g/t. Underground development is advancing, with the Waihi North decline now 350 m, first vent shaft under construction, staged commissioning of a new water treatment plant, and early works on a new tailings storage facility due in Q4.

Two low‑carbon heat network schemes spanning seven London boroughs have secured a combined £53.1M in government funding to expand district-scale, pipe‑fed heating infrastructure. The awards back large‑diameter buried distribution mains, central energy centres and building‑level heat interface units designed to displace individual gas boilers in dense urban housing and mixed‑use stock. For civil and geotechnical teams, the projects signal substantial trenching, utility coordination and shaft works in constrained streets, with long linear workfronts and tight programmes across multiple local authorities.

Kinross Gold has cut its 2026–27 production outlook by about 8% to 1.84–1.86 million attributable gold-equivalent oz. a year and raised 2024 AISC guidance to $1,850–$1,900/oz after winter storms, copper-rich sulphide ore and poor recoveries at La Coipa in Chile, plus weaker mining rates, grades and recoveries at Round Mountain Phase S in Nevada. The company is stockpiling high-copper material, studying a new flotation circuit for deeper sulphide mineralisation that may overlie a copper porphyry system, and using a smaller shovel at Round Mountain to cut dilution. Despite the operational hit and a Q3 output cut to about 425,000 oz., Kinross has lifted its 2026 shareholder return target to 50% of free cash flow and has already returned about $800 million this year, mainly via $655 million in buybacks.

Rainbow Rare Earths has secured an offtake and processing memorandum with Neo Performance Materials covering 40% of Phalaborwa’s separated NdPr oxide and 65% of its mixed SEG+ heavy rare earth carbonate, enabling a prefeasibility study in Q4 and pushing the definitive feasibility study to the first half of 2027. Neo will supply solvent extraction design and technical support, with test work on phosphogypsum-derived feed under way in Estonia and an integrated pilot planned in Johannesburg, de-risking the complex separation of dysprosium, terbium and yttrium. The $326 million project would recover magnet rare earths from legacy fertiliser gypsum stacks, potentially feeding Neo’s Estonian separation and sintered magnet plant and offering a non-Chinese supply route linked to European capacity.

Southern Water is rolling out a distributed fibre‑optic leak‑detection system from UK firm Lightsonic on trunk mains across the south of England to cut losses as drought risk and network age increase. The technology uses continuous fibre along the pipeline to sense acoustic and temperature changes in real time, allowing operators to pinpoint leaks to within metres and respond before major bursts develop. For civil and water engineers, this signals growing deployment of long‑range, permanently installed monitoring rather than spot surveys on critical transmission assets.

Rio Tinto plans a major expansion of its metals trading arm into third‑party material and derivatives, leveraging spare alumina and copper capacity rather than limiting activity to its own output. The move, led by chief commercial officer Bold Baatar, targets markets where existing assets give an edge, including alumina imbalances between regions and unused smelting capacity at the Kennecott copper operations in North America, and may extend to copper cathode and sulphuric acid. The commercial team of about 20 traders is set to grow, and Rio is in talks with Vitol on a freight and logistics joint venture.

Glencore will begin trading on the Australian Securities Exchange on 14 October under ticker GLC via CHESS Depositary Interests, each representing one ordinary share, without issuing new equity or raising capital. The Swiss miner is targeting access to Australia’s A$4.4 trillion pension market to fund copper growth and potential acquisitions, after previously exploring a New York listing and a coal spin-off. UK and South African shareholders can convert existing holdings into ASX-listed CDIs from 24 September, with Computershare managing the Australian register.

Network Rail will invest £1.4M to renew over 730m of track between Hubbert’s Bridge and Swineshead on the Boston–Sleaford line in Lincolnshire, targeting a known maintenance pinch point. Works will involve lifting and replacing rail, sleepers and ballast on this rural two-track section, where drainage and formation condition have previously constrained line speed and imposed temporary speed restrictions. Contractors will need to manage possessions on a mixed-traffic route carrying passenger services and agricultural freight, with careful staging to minimise disruption during the renewal.

Sandvik Australia has launched its 2026–2028 Innovate Reconciliation Action Plan, marking a decade of formal reconciliation work and setting a minimum target of 3.5% Aboriginal and Torres Strait Islander representation in its workforce.

Geoscience Australia has released the Green Iron StoryMap, an interactive tool within the Digital Atlas of Australia that layers iron ore deposits, renewable energy zones, existing rail and port corridors, and water resources to map green iron potential. Users can interrogate spatial data on proximity of high‑grade ore bodies to wind and solar resources, transmission lines and gas pipelines, helping screen locations for hydrogen‑based direct reduction or electrified pelletising. For miners and infrastructure planners, it offers a first‑pass, national‑scale view of where integrated green iron hubs could be technically viable.

Auric Mining has reported strong new drilling results at the Munda gold project near Widgiemooltha, WA, as it works towards restarting open-pit mining in 2027. Broad-spaced reverse circulation drilling is testing resource extensions beyond the current pit shell, while closer-spaced grade-control holes are refining ore boundaries within the planned open pit. Additional sterilisation drilling is being completed in proposed infrastructure corridors, with outcomes likely to influence final pit design, haul road alignment and plant or waste-dump siting.

Delivering a 505km high-voltage “electricity superhighway” between Scotland and England is exposing complex consenting, land access and interface issues across multiple local authorities and environmentally sensitive corridors. Engineers are having to integrate new high-capacity transmission circuits with existing substations and overhead line routes while maintaining system security, often relying on long HDD river crossings, constrained construction compounds and tight outage windows. The project is setting practical benchmarks for routing, stakeholder management and constructability on future UK grid reinforcements needed for large-scale offshore wind and other renewables.

STRABAG Australia has agreed to acquire KEE Surfacing from the KEE Group, combining STRABAG’s global road construction, materials production and asphalt technology capability with KEE’s established Western Australian surfacing operations.

High-grade rare earth intercepts at Rare Earths Americas’ 100%-owned Homer project in Brazil’s Goiás Alkaline province include multiple near-surface intervals above 2,000 ppm TREO over >10 m within clay-hosted soil and saprolite profiles. A fully funded US$5 million, 15,000 m reverse circulation and diamond drilling programme, now running four rigs, has already drilled 6,500 m and confirmed mineralisation across ~2.15 km², less than 7% of the 35 km² ring-shaped magnetic anomaly. Assays show heavy rare earth enrichment with HREO >30% of TREO, NdPr >25%, Dy+Tb >2%, plus niobium, tantalum and notable scandium requiring metallurgical evaluation.

BHP has suspended all operational activities at the Escondida copper mine in Chile’s Antofagasta region after a worker was killed during maintenance involving a front-end loader, with Chile’s Sernageomin deploying a regional investigation team to site. The fatality comes as BHP, which holds a 57.5% stake in Escondida alongside Rio Tinto’s 30%, is in contract negotiations with mine workers, with a vote due by the end of September. Any prolonged shutdown or subsequent strike could materially disrupt output at the world’s largest copper mine.

Glencore has halted rail operations at its Cerrejón coal mine in Colombia after explosives hit its 150 km railway near Uribia, La Guajira, damaging a train in the sixth attack on the corridor this year. The mine itself, one of the world’s largest open pits with 2025 output of 16.8 million tonnes, continues operating while the National Army secures the line and engineers await access for damage assessment. Prolonged repairs could again choke inbound supplies and coal exports via Puerto Bolívar, exposing the operation’s heavy reliance on a single transport corridor.

Higher pre-production capital of US$1.43 billion, up 15% year-on-year, is weighing on Ivanhoe Electric’s Santa Cruz copper project even as the updated PFS lifts NPV to US$1.5 billion and extends mine life to 24 years with average output of about 74,700 tonnes of copper per year for the first 15 years. The redesign swaps a roadheader access for a Robbins Crossover TBM and a new access tunnel to reduce groundwater risk, pushing first cathode to 2029 and trimming IRR to 19% with a 4.8-year payback at US$4.75/lb copper. Shares fell 4.2% to US$10.27 as management advances EXIM Bank due diligence for up to US$1.1 billion in debt, with life-of-mine cash costs projected at US$1.47/lb and AISC at US$2.28/lb.

The deployment will span exploration, mine planning, safety, production, processing and maintenance, creating a single environment for ingesting sensor data, operational KPIs and engineering rules. For mine operators and engineers, this signals a push towards integrated decision support, where planning, plant control and asset health monitoring are driven from one AI-enabled operational backbone rather than siloed systems.

Highlander Silver has mandated Natixis CIB to arrange a fully underwritten US$330 million, seven‑year senior secured debt package, including a US$100 million cost‑overrun provision, to fund construction of the fully permitted Corani silver‑lead‑zinc project in Peru’s Puno region. Corani hosts 138.6 million tonnes of proven and probable reserves grading 51.3 g/t silver, 0.9% lead and 0.55% zinc (229 million oz silver, 2.7 billion lb lead, 1.7 billion lb zinc), with the 2019 feasibility outlining a 15‑year mine averaging 9.6 million oz silver per year at US$4.55/oz AISC. With about US$100 million cash on hand, expected Mercedes mine cash flow of roughly US$100 million in 2027–28, and the Natixis facility projected to cover ~72% of the ~US$460–500 million capex, BMO and Scotiabank see Corani nearing fully funded status, targeting construction start in H1 2027 and first production by end‑2029.

Former Gold Fields CEO Chris Griffith has joined a new private equity team aiming to raise $1 billion for African critical minerals projects, targeting commodities such as cobalt, copper, lithium, nickel and rare earths. He is working with former Goldman Sachs banker Colin Coleman and ex-Ashanti Goldfields chair Sam Jonah, with fundraising still at an early stage and structured as a dedicated Africa-focused vehicle. The move follows Griffith’s exit from Gold Fields after the failed $6.7 billion Yamana bid and a subsequent two-year spell leading Vedanta’s base metals division.

Grid connection delays of up to 10 years are deterring investment in UK infrastructure, according to a new report by Centrica and climate think tank Ceres. The report warns that major low‑carbon schemes, including large-scale renewables and grid‑scale battery storage, are being forced into long connection queues despite available capital and consented sites. For civil and energy engineers, the key risk is stranded or re‑phased projects where grid access, not design or finance, becomes the critical path constraint.

SuperCritical Materials Corp. has partnered with the University of Michigan to mechanically validate its uranium‑from‑seawater adsorbent for industrial‑scale offshore deployment, using hydrodynamic testing in the Aaron Friedman Marine Hydrodynamics Laboratory’s wave and current tanks. The programme will characterise the adsorbent under packing, deployment, ocean exposure and retrieval stresses, optimise packing configurations, and build and test prototypes for repeated deployment–recovery cycles. Findings will feed into a future feasibility study and nearshore pilot designs, targeting integration of seawater‑derived uranium into the US nuclear‑fuel supply chain.

US Export-Import Bank is preparing up to $7 billion in financing for Argentine critical minerals and energy projects, enabling operators to fund US-sourced equipment for lithium, copper, rare earths and shale oil and gas over the next two years. The package would build on more than $1 billion in US critical minerals commitments to Latin America since January 2025 and sits alongside Argentina’s RIGI regime, which grants tax, customs and FX stability for projects above $200 million. Key beneficiaries could include Rio Tinto’s $2.5 billion Rincón lithium project, BHP’s advancing copper developments and Chevron’s shale operations, with Argentina targeting 580,000 t/y lithium and 1.64 Mt/y copper exports by 2036.

Wolfram Bergbau und Hütten AG marks 50 years of operation as Europe’s only fully integrated tungsten producer, running mining, refining and recycling from a single chain centred on its Austrian Alps deposit. The company’s model couples primary ore extraction with secondary raw materials, using in-house recycling of hardmetal scrap and tungsten-containing residues to buffer supply risk. For mine planners and metallurgists, Wolfram’s history illustrates how regional processing capacity and closed-loop scrap flows can stabilise a critical metal traditionally dominated by Chinese concentrate and APT exports.

Improved public–private collaboration, “smarter” financial risk sharing and better asset data are being urged by a new Lloyds Banking Group report to upgrade the UK’s ageing, climate-exposed infrastructure. The report calls for clearer allocation of construction, demand and climate risks between government, institutional investors and asset owners, moving beyond traditional PFI-style models. For engineers, this points to stronger requirements for whole-life performance data, climate stress testing of assets and more transparent condition information to unlock private capital for renewals and resilience upgrades.
