The project signals growing confidence in HPGR performance under low‑oxygen, low‑temperature conditions, with implications for power draw, wear behaviour and maintenance planning at high‑altitude sites.

First Quantum Minerals has filed a new NI 43-101 Technical Report for its Taca Taca porphyry copper-gold-molybdenum project in Argentina’s Puna region, again incorporating the option of trolley-assist haulage for the open pit. The study continues to evaluate overhead electric trolley lines on key ramp segments to cut diesel consumption and unit costs for large ultra-class haul trucks. For mine planners and electrical engineers, the report signals ongoing commitment to high-capacity pit electrification rather than a purely diesel truck fleet.

A prolonged Iran conflict that drives oil above $150 a barrel and constrains Strait of Hormuz flows could cap global copper demand growth at 0.5%–1%, push prices below $10,000/t and create a 100,000–200,000 t refined surplus, Bloomberg Intelligence warns. Under this scenario, 2026 earnings may drop about 20% at Southern Copper, 32% at Antofagasta and up to 55% at First Quantum, with unit costs rising 10%–20% and high-cost producer margins compressing from ~70% to ~40%. Sulfur and sulfuric acid supply from the Gulf emerges as a key constraint, particularly for DRC operations where 50%–60% of output depends on acid leaching.

Gemfields expects a 2025 loss per share of 2.6¢, narrowed from 7¢ in 2024, as weaker gemstone prices, illegal mining and grade volatility hit the Montepuez ruby mine in Mozambique and the Kagem emerald mine in Zambia, cutting output and cash flow. Commissioning of Montepuez’s second processing plant, already producing rubies since September 2025, is now delayed well into H1 2026, constraining volume recovery and auction scheduling. Seven gemstone auctions raised $129 million in 2025, down 34% from $195.9 million, despite firmer prices for top-tier emeralds and rubies.

Komatsu has run its 2026 North America Advanced Technician Competition at its Cartersville Customer Center in Georgia, putting 10 dealer-network diesel technicians through two days of scored tasks.

For mine operators, the move signals closer integration between support hardware and tailored chemical formulations, with potential gains in early strength, adhesion and durability of ground support systems.

Tudor Gold has dropped its appeal of a British Columbia Chief Gold Commissioner ruling over Seabridge Gold’s Mitchell Treaty Tunnels (MTT), easing one legal obstacle to the C$6.4 billion KSM gold-copper project but leaving two BC court actions active. The dispute centres on about 12.5 km of Seabridge’s planned 22-km twin access tunnels, each roughly 5.9 m by 5.5 m, crossing Tudor’s Treaty Creek claims and, Tudor says, sterilising parts of the Goldstorm, Perfectstorm and CBS zones. Goldstorm alone hosts 912.3 million tonnes indicated at 0.85 g/t Au, 5.07 g/t Ag and 0.15% Cu, so tunnel buffer zones could materially constrain future underground layouts and access.

Zijin Gold is taking effective control of rival Chifeng Jilong Gold Mining in an 18.26 billion yuan ($2.64 billion) deal, lifting its stake to nearly 26% through a mix of mainland-listed and newly issued Hong Kong shares and enabling full financial consolidation. Chifeng produced about 14.4 tonnes of gold in 2025 from mines in China, Ghana and Laos, versus Zijin Gold’s 46.6 tonnes, with analysts expecting operating efficiencies under Zijin’s management. The move follows Zijin’s C$5.5 billion acquisition of Allied Gold and signals continued Chinese expansion into overseas gold assets amid bullion prices still above $5,000/oz highs earlier this year.

For geotechnical and mining teams, the project signals continued investment in legacy Copperbelt infrastructure rather than greenfield capacity, with implications for ground support strategies and life-of-mine planning.

CAPS Australia is deploying modular nitrogen generators and compressed air systems from global OEM partners to support underground mining maintenance in Australian operations. The skid-mounted nitrogen units are engineered to match site-specific pressure, purity and flow requirements for tasks such as tyre inflation, longwall equipment servicing and inerting, reducing reliance on delivered gas cylinders. For mine operators, the key shift is towards on-site, containerised utilities that can be scaled or relocated between declines and workshops as production layouts change.

Globe Metals and Mining is advancing the Kanyika niobium project in Malawi, aiming to challenge Brazil and Canada’s dominance in a market where niobium has no practical substitutes in high-strength low-alloy steels and advanced alloys. The project targets niobium and tantalum concentrates for use in micro-alloyed structural steels, gas pipelines and high-temperature turbine components, where small niobium additions (typically <0.1 per cent) deliver major strength and weldability gains. For miners and metallurgists, Kanyika signals emerging African supply that could reshape long-term offtake, pricing and risk strategies for niobium-dependent steel and superalloy producers.

Structural testing is presented as a non-negotiable step for mining infrastructure, validating the integrity and fatigue performance of critical assets such as conveyor gantries, processing plant platforms, and heavy-equipment support frames. Australian Mining Services (AMS) is cited using load testing, strain gauging and non-destructive examination on welded joints, bolted connections and high-stress nodes to detect cracking and deformation before service failures occur. For engineers, the message is to embed scheduled structural testing into lifecycle management, particularly where dynamic loads, corrosion, and vibration govern design behaviour.

Macmahon Holdings has signed a Letter of Intent with Wolfram Limited, a Bumi Resources subsidiary, to restart the Mount Carlton Gold Mine in north Queensland, covering both surface and underground mining plus associated civil infrastructure works. The scope is expected to include open-pit and underground production, haul road and ROM pad construction, and potential tailings and water management upgrades typical of a brownfield restart. Contractors and suppliers should anticipate tenders for fleet, ground support, drill-and-blast, and civil packages once the LoI progresses to a full mining services contract.

Alligator Energy has begun uranium extraction in the field leach trial at its Samphire in-situ recovery (ISR) project near Whyalla, South Australia, a key step towards proving commercial ISR performance in the Eyre Peninsula’s shallow sandstone aquifers. The trial will operate a closed-circuit lixiviant system through a dedicated wellfield to generate real-time data on uranium recovery, solution chemistry and groundwater behaviour under controlled drawdown. Results will drive final well spacing, pump sizing and process plant design, and feed into regulatory approvals for full-scale ISR mining.
