Mining stocks reversed sharply as copper producers Freeport-McMoRan and Teck Resources fell about 7% after a report that the White House has yet to decide on refined copper tariffs. The pullback comes just as Freeport’s $100 billion valuation is again in focus, magnifying sensitivity to policy risk around US trade measures. For mine planners and project financiers, the move signals renewed volatility in copper, silver and gold pricing that could affect hurdle rates, hedging strategies and near-term approvals for large capital projects.

Platinum and palladium price forecasts have been cut by BMI as shrinking global car sales curb autocatalyst demand and South African PGM supply recovers, easing earlier deficit concerns. Sibanye-Stillwater is restructuring a loss-making shaft in South Africa and simultaneously facing a strike at its Stillwater and East Boulder palladium operations in Montana, adding mine-level uncertainty. The World Platinum Investment Council estimates above-ground platinum stocks will fall to cover only about 3.4 months of demand by year-end, signalling tighter physical availability despite softer prices.

Orica Digital Solutions has released a next-generation FRAGTrack™ system that can now be deployed on excavators, pushing fragmentation measurement directly to the dig face rather than relying solely on fixed crusher or conveyor installations. The upgraded hardware platform delivers higher-resolution image capture and faster on-board processing, giving mine operators near real-time particle size distribution data to tune blast designs, loader bucket selection and crusher settings. Closer-to-face deployment should reduce sampling bias from oversize rejection and improve calibration of blast models against actual muckpile fragmentation.

The University of Arizona has secured $20 million from the US Department of Energy’s Office of Critical Minerals and Energy Innovation to expand and upgrade its San Xavier Underground Mining Laboratory.

For mine planners and contractors, the deal signals stable medium-term demand for bulk logistics capacity and sustained production scheduling at Davyhurst.

Codelco’s Ventanas Division has become the company’s first operation to reach 100% electromobility for worker transport, launching a fully zero-emission industrial bus and shuttle fleet on World Electric Vehicle Day in Chile’s Valparaíso Region. The system replaces all previous diesel-based personnel transport on internal routes, cutting tailpipe emissions to zero at the smelter–refinery complex and reducing noise and particulate exposure along access roads and loading areas. Regional Energy and Mining Secretaries Celso Quezada and Cristian Vasseur attended, signalling regulatory backing for wider fleet electrification across Codelco sites.

Metso has launched the Sampo Cell coarse particle flotation technology, designed to increase recovery of coarse particles while maintaining fine particle performance in conventional flotation circuits. The cell targets more complex, lower-grade ores where coarse gangue rejection and reduced overgrinding can cut specific energy use and tailings volumes. For plant designers and metallurgists, the concept enables coarser primary grind sizes, potential debottlenecking of milling, and improved overall circuit recovery without wholesale replacement of existing flotation banks.

Master Drilling has secured its first Portuguese contract from copper-zinc producer Boliden Somincor to construct two raisebored shafts, each 630 m deep and 4.5 m in diameter. The twin vertical excavations will be critical for long-term hoisting, ventilation or service access, demanding precise control of deviation over the full 630 m and careful management of rock stability around the 4.5 m diameter openings. For geotechnical and mine planning teams, the project signals growing availability of large-diameter raiseboring capacity in European base metal operations.

Metso has expanded its Metso Digital portfolio with three new platforms – Digital Production Management, Data-driven Performance Analytics and Safety Performance Platform – aimed at turning plant and fleet data into actionable production and safety decisions.

Stage One of New South Wales’ $130 million Avoca Drive Upgrade is starting 18 months early on the Central Coast, where the two-lane east–west arterial currently carries about 26,000 vehicles per day and is a known congestion pinch point. Funded by $100 million from the Federal Government and $30 million from NSW, the works will focus on upgrading Avoca Drive’s capacity and geometry. Civil contractors can expect complex traffic staging and pavement reconstruction on a constrained corridor that must remain operational throughout construction.

Catalyst Metals has lifted the Mineral Resource at its Keillor gold mine in Western Australia by about 280 per cent to 3.2 million tonnes at 3.0g/t gold for 307,000oz, up from 81,000oz. The company is targeting an extension of the operation beyond its initial three‑year mine life, signalling scope for revised pit designs, updated production schedules and potential plant throughput adjustments. Geotechnical and mine planning teams will need to reassess slope designs, sequencing and ground support to accommodate the larger, higher‑confidence inventory.

Forrestania Resources has moved to restart the Edna May Gold Project in Western Australia after completing its $210 million acquisition from Ramelius Resources on 4 September, securing a suite of operational and supply agreements to underpin the transition. The company is developing a two-hub processing strategy, with Edna May as a central processing facility integrated with its existing Western Australian assets to optimise mill utilisation and ore haulage. For mine planners and metallurgists, the agreements de‑risk near‑term feed, contracting and processing routes ahead of a formal restart decision.

Gateway Mining is preparing first-pass air core drilling in early October over its newly defined 3km-long Pewy gold target within the Yandal gold project in Western Australia, testing a major untested structural corridor immediately south of the Ward prospect. The programme will focus on shallow AC holes to map oxide and transported cover geochemistry across the full strike length, aiming to vector towards primary bedrock mineralisation. For geologists and mine planners, results will clarify structural controls and help prioritise follow-up RC or diamond drilling in the broader Yandal belt.

Consent from the Nyangumarta People for Rio Tinto’s proposed Winu copper–gold mine in Western Australia clears a key approvals hurdle as the project targets first copper by 2030. The project agreement between the Nyangumarta Warrarn Aboriginal Corporation and Rio Tinto covers the mine and associated infrastructure on Nyangumarta Country, including access corridors and services. For project teams, the deal provides a framework for land access, cultural heritage management and scheduling of early works, enabling more detailed mine design and infrastructure planning to proceed.

Tungsten Mining’s Watershed project in Far North Queensland is now fully permitted for mining and production, with all primary approvals secured, including its Environmental Authority and Progressive Rehabilitation and Closure Plan. The company is targeting a final investment decision later in 2026 on the 100 per cent-owned tungsten deposit, which is positioned as a long-life open-pit operation. Full permitting de-risks project scheduling for mine development, tailings and waste landforms, and staged rehabilitation, giving contractors and financiers clearer visibility on execution and closure obligations.
