Exploration activity across Australia’s gold and critical minerals sector is intensifying, with Kali Metals and Kairos Minerals (soon to be renamed) among juniors reporting new results. Kali has intersected shallow, high-grade gold, signalling potential for low-strip, open-pit development and relatively simple geotechnical access compared with deeper lode systems. For mine planners and drill contractors, the focus now shifts to tighter step-out drilling, resource definition, and early metallurgical testwork to confirm recoveries and guide pit shell optimisation.

Western Australia is moving to tighten transparency across its diesel and fuel supply chain to protect mine productivity, with new reporting obligations on wholesalers and critical infrastructure operators after recent shipping disruptions and refinery closures. The measures focus on real‑time visibility of stock levels, import routes and storage at key hubs such as Kwinana and Port Hedland, aiming to reduce unplanned shutdown risk for large open‑pit iron ore and gold operations that rely on continuous haul‑truck and power‑generation fuel. For mine planners and operators, the changes signal closer scrutiny of fuel contingency planning, on‑site storage capacity and contract diversification.

US rare earth strategy is shifting from securing ore to controlling processing, with Aclara Resources’ Virginia Tech pilot and planned Louisiana separation plant illustrating a policy pivot towards domestic heavy rare earth separation for dysprosium and terbium used in EVs, wind and defence. Patricio Faúndez, economics leader at GEM Mining Consulting, notes Washington is now deploying price floors, equity stakes and long-term offtakes—tools long associated with China—to de-risk capital-intensive plants. The emerging model favours allied feedstock plus US-based processing, redistributing supply risk across jurisdictions rather than eliminating it.

Wheaton Precious Metals has agreed a US$4.3‑billion silver stream with BHP, securing 33% of silver output from the Antamina copper‑zinc mine in Peru, dropping to 22.5% after 100 million oz, with ongoing transfer payments fixed at 20% of spot and settlement via metal credits. In parallel, Wheaton will invest US$275 million in KGL Resources’ fully permitted Jervois copper project in Australia, taking staged gold and silver streams starting at 75% of payable production and tapering to 25% over mine life. The deals extend Wheaton’s exposure to large, long‑life base‑metal operations while diversifying into Australia.

Cerrado Gold has filed an injunction against Portugal’s environmental regulator APA over the rejection of its Lagoa Salgada copper-zinc project in the Iberian pyrite belt, arguing procedural flaws including an eight-day instead of legally required 10-day consultation and a late-stage objection over a deep, sulphide-contaminated third aquifer earmarked for mine water use. Municipal authorities near Grândola cite conflicts with land-use plans and water risks, despite the project’s Project of National Interest status and extensive hydrological studies. CEO Mark Brennan still targets first production in 2028, with cash flow from the 50,238 oz Au-eq/y Minera Don Nicolás mine and potential offtake/streaming expected to fund development.

First Majestic Silver plans to restart the fully permitted Jerritt Canyon gold mine in Nevada by late 2027, backed by a 2026 spend of US$75 million on technical work, underground development, exploration and plant upgrades and a PFS due in Q4 2026. Updated resources stand at 54.3 million measured and indicated tonnes at 2.35 g/t Au (4.1 Moz) plus 46.6 million inferred tonnes at 2.44 g/t Au (3.66 Moz), following an 18,000-metre 2025 drill campaign and 42,000 metres planned for 2026. The revamped plan combines existing underground workings with new open‑pit potential around the SSX and Smith deposits, seeking to optimise long-term throughput through the roaster-based processing plant.

Atlas Lithium’s Neves project in Minas Gerais, Brazil, has been named in the US-Japan critical minerals cooperation joint fact sheet as the only Brazil-based lithium asset under consideration for government-backed funding, following last month’s US-Japan Critical Minerals Investment Ministerial in Tokyo. The pre-production project will process ore from the Neves deposit through a dense media separation plant to produce lithium concentrate, targeting 300,000 tonnes per year. A 2025 definitive feasibility study projects an after-tax IRR of 145%, NPV of $539 million and an 11‑month payback, supported by a $30 million Mitsui & Co. investment and offtake deal.

United States Antimony Corp. has restarted mining at its Stibnite Hill property in Montana after a near five‑month weather-related halt, resuming ore supply to its Radersburg flotation mill and Thompson Falls smelter, the only antimony smelter in the US. The integrated route can currently produce about 15 million lb/year of antimony oxide or 5 million lb/year of antimony metal, with expansion underway and early test work suggesting the ore can be upgraded to meet military specifications. The 2026 programme adds on-site chipping for mulch-based concurrent reclamation and GPS base stations on adjacent peaks to improve vein mapping on strike and down dip.

China’s Zijin Mining is expanding RG Gold’s Raygorodok operation in Kazakhstan with a $500 million processing plant while deploying SKRI’s ‘phytocapture’ system, planting over 100,000 Scots pines across more than 20 hectares about 1.7 km downwind of the open pit. Supercomputer modelling using regional wind-rose data sets tree species and spacing to form multilayered vegetative barriers, not simple landscaping. SKRI reports particulate-matter reductions above 40%, with the forest belt expected to capture roughly one-third of dust emissions as mining advances towards the barrier.

Barrick Mining has warned of “significant increases” to the capital budget and schedule for the 50%-owned Reko Diq copper-gold project in Balochistan, where Phase 1 was previously costed at US$5.6–6.0 billion and Phase 2 at US$3.3–3.6 billion, with first production targeted by end-2028. Citing escalating security risks in Pakistan and the wider region, Barrick will slow field development and extend the technical and financing review to mid‑2027, while keeping the project under “active management” with reduced capital spend. The porphyry deposit, holding an estimated 15 million tonnes of copper reserves and modelled for a 37‑year mine life, remains central to Barrick’s Tier 1 copper strategy and its long-term community commitments in Balochistan.

Queensland’s Department of Transport and Main Roads has issued a detailed design tender for two new south-facing ramps connecting to the Sunshine Motorway at Mount Coolum, tied to an upgrade of the Sunshine Motorway–West Coolum Road interchange. The scheme must integrate with Sunshine Coast Regional Council’s planned link between Suncoast Beach Drive, South Coolum Road and West Coolum Road, creating a new local–motorway interface. Designers will need to resolve ramp geometry, weaving lengths and tie-ins to existing pavement while accommodating future council road connections.

Barratt Redrow has appointed GTC to deliver a site-wide smart energy system for the 576-home Cosmeston Farm scheme in Wales, targeting operational net zero carbon and outperforming the Future Homes Standard. The integrated package links networked ground source heat pumps, solar PV, home battery storage, smart controls and optimisation, grid flexibility services, and GTC-owned electricity and water networks, while still allowing residents to choose their electricity supplier. GTC will monitor whole-home energy use and local network performance, with Cardiff University independently reviewing data to verify net zero operation at scale.

Difficulties implementing mandatory Biodiversity Net Gain (BNG) are slowing housing projects, with a Home Builders Federation survey of 80 firms finding 84% still struggle with BNG and 80% reporting planning delays while local authorities review biodiversity assessments. Sixty per cent said BNG has deterred them from pursuing sites that would previously have been viable, citing policy uncertainty, inconsistent application of requirements and cumulative regulatory cost. Some capacity issues are easing, with reported shortages of in-house expertise down from 79% to 66% and adequate off-site biodiversity unit supply up from 31% to 47%.

Electrification of mining fleets is advancing beyond early pilots, with battery-electric haul trucks, loaders and light vehicles moving from trial phases into multi-year deployment contracts despite recent pull-backs in some OEM roadmaps. Dan Gleeson details how mines are pairing 6–8 MWh battery trucks with on-site fast-charging bays and trolley-assist lines, and integrating underground BEVs with upgraded 11 kV substations and ventilation recalculations. Operators are reassessing mine plans, ramp gradients and power quality to manage peak loads, charger placement and heat rejection from high-capacity battery systems.

Aggreko has signed a minimum 15‑year power purchase agreement with Harmony Gold to build and operate what is described as Australia’s largest off‑grid renewable hybrid power facility for the Eva copper project in northwest Queensland. The build‑own‑operate arrangement will combine on‑site renewables with thermal generation and battery storage to supply continuous power to the remote open‑pit operation. For mine planners and process engineers, the long‑term PPA locks in a dedicated low‑emission power source, influencing pit expansion options, processing throughput and future electrification of mobile fleets.

Metso has launched the Outotec Robotic Split Strip, a compact hydraulic‑robotic system for separating copper cathode sheets from mother plates in electrorefining circuits, designed for both greenfield and brownfield plants. The unit uses robotic handling and flexible tooling to improve stripping precision and reduce sheet damage and copper waste compared with conventional mechanical strippers. For plant engineers, the modular layout and automation focus allow retrofit into existing cells with minimal footprint, supporting tighter process control and more consistent cathode quality.

More than $107 million from the latest round of the Federal Government’s Safer Local Roads and Infrastructure Program (SLRIP) will fund 42 new road projects across Australia, targeting safety and productivity upgrades. Over $91 million of this is allocated to projects on nationally significant routes, supporting works such as intersection treatments, shoulder widening and pavement rehabilitation. Designers and contractors can expect a pipeline of small to medium packages focused on reducing crash risk and improving freight efficiency on existing corridors.

South Australia’s $15.4 billion River Torrens to Darlington (T2D) project has installed the first of three 300‑tonne tunnel boring machine cutterheads, a key step in delivering Adelaide’s non‑stop north–south transport corridor. The lift confirms TBM assembly is advancing on schedule for the twin‑tunnel section, which will carry high‑volume traffic beneath existing urban development. For civil and geotechnical teams, the milestone signals imminent full‑face tunnelling, with associated demands on segment lining logistics, spoil management and settlement monitoring in densely built areas.

Approval of a 60 per cent Supplementary Cementitious Material (SCM) concrete mix by VicRoads for road and transport projects across Victoria marks a major shift in allowable low-carbon binders for state infrastructure. The mix, developed and trialled with Geoquest Australia, replaces the majority of Portland cement with SCMs such as fly ash and slag, cutting embodied carbon while maintaining performance to VicRoads specifications. Designers and contractors can now specify substantially higher SCM contents on VicRoads projects without seeking project-by-project exemptions.

Victory Metals has reported “exceptional” metallurgical leaching results from its 100 per cent-owned North Stanmore heavy rare earth project in Western Australia, with a particular uplift in yttrium recoveries. The company is advancing column leach tests and optimisation of acid consumption after earlier bottle-roll work, targeting a clay-hosted rare earth system amenable to low-cost in-situ or heap leach-style processing. For geometallurgy and mine design, the results point to potential simplification of beneficiation flowsheets and greater emphasis on leach pad hydrology and solution management rather than complex concentrator circuits.

Aggreko has signed a long-term power purchase agreement with Harmony Gold to build and operate what is billed as Australia’s largest hybrid power facility for the Eva copper mine project in northwest Queensland. The off-grid system is expected to combine high-penetration solar PV with thermal generation and battery energy storage, replacing conventional diesel-heavy supply for the planned open-pit copper operation. For mine planners and owners, the deal signals growing bankability of large-scale hybrid PPAs to cut power costs and emissions on remote greenfield sites.

Ausenco has secured an engineering, procurement and construction management (EPCM) contract for the Hillside copper project, signalling progression towards full project execution after a prolonged permitting and feasibility phase. The mandate covers process plant design, materials handling and associated infrastructure, positioning Ausenco to define key specifications for concentrator throughput, tailings management and power supply. For geotechnical and civil teams, the EPCM scope will drive final decisions on pit geotechnics, foundation systems for heavy plant and haul road geometry ahead of construction mobilisation.
