Soma Gold Corp is advancing a mineralised material upgrading strategy at its El Bagre underground operation in Colombia using TOMRA Mining’s sensor-based sorter that combines XRT technology with OBTAIN™ and CONTAIN™ AI-based image processing. Positive test work at TOMRA’s Test Center in Germany showed sufficient ore–waste discrimination to justify implementation, targeting higher feed grades and reduced haulage and processing of low-value material. For mine planners and process engineers, the move signals a shift towards pre-concentration at the mine gate, with potential impacts on cut-off grade, stope design and plant throughput.

Yancoal Australia has agreed to buy an 80% stake in the Kestrel underground coking coal mine in Queensland’s Bowen Basin from EMR Capital and Alamtri Resources for up to $2.4 billion, comprising $1.85 billion upfront and as much as $550 million in contingent payments over five years. The acquisition, funded via cash and a $1.2 billion five-year syndicated loan, adds Australia’s largest producing underground coal mine, which delivered 5.9 Mt of saleable coal in 2025, to Yancoal’s portfolio near its Middlemount JV and Yarrabee operations. Completion is targeted by Q3 2026, with Mitsui retaining its 20% stake.

Kodal Minerals reported record quarterly output from the Bougouni lithium mine in Mali, producing 26,981 tonnes of 5.28% Li₂O spodumene concentrate, with March alone exceeding 10,900 tonnes. Two shipments lifted total exports to about 49,000 tonnes and generated more than $51 million in revenue, as plant upgrades and mining changes improved throughput and reliability, according to CEO Bernard Aylward. A Phase Two flotation plant remains under feasibility study, signalling potential capacity expansion at Mali’s second active lithium operation, 180 km from Bamako.

Mexican security forces rescued Taxco mayor Juan Andrés Vega Carranza and his father in Guerrero after a weekend abduction, in an operation involving the defence ministry, navy and national guard, with arrests still pending. The incident follows the January kidnapping of 10 workers from Vizsla Silver’s Panuco project in Sinaloa, where nine were later confirmed dead and operations were suspended. Vizsla’s share price has since fallen by about 50%, signalling heightened security and continuity risk for mine operators in cartel-affected regions.

Canadian Copper has secured up to C$96 million from OR Royalties and Ocean Partners UK to advance the Murray Brook VMS deposit and upgrade the nearby Caribou processing plant within the Bathurst mining complex in New Brunswick. Murray Brook hosts 21.1 million tonnes measured and indicated at 0.45% copper (211.7 million lb contained), plus zinc, gold and silver, and is described as the province’s largest undeveloped VMS deposit. The package combines a 20% life-of-mine silver-gold stream, up to C$48 million in project debt at SOFR + 7.75%, and equity at a 20% share price premium, fully covering PEA capex.

Montage Gold has secured five greenfield gold exploration permits in northern Mauritania, covering over 2,100 km² across the Sfariat and Zednes blocks, with 80% rights in the latter after a competitive tender. The move extends its West African portfolio beyond Côte d’Ivoire, where the Koné project is targeting first gold by year-end and forecast output of over 300,000 oz per year for the first eight years. Management says the Mauritanian tenements were prioritised using existing geophysical, geochemical and geological mapping datasets.

Aura Minerals has approved full construction of the Era Dorada underground gold project in southeast Guatemala, a 17‑year mine plan for 1.75 million oz gold equivalent with average output of 111,000 oz/y in the first four years. Updated capex is now US$386–453 million, up from an earlier US$236–278 million early‑works estimate, with US$262–314 million allocated to full project expansion while exploration and sustaining costs remain unchanged. The former Cerro Blanco project will stay underground rather than shift to open pit, with specific infrastructure budgeted to address community concerns over water quality.

Omai Gold Mines has increased total resources at its past-producing Omai project in central Guyana to 8 million oz., up from 6.5 million oz., with indicated resources now 38.1 million tonnes at 2.04 g/t and inferred 106.6 million tonnes at 1.59 g/t, after 18,000 metres of drilling and updated modelling. The Wenot open-pit deposit now holds about 1.45 million oz. indicated at 1.59 g/t and 3.9 million oz. inferred at 1.33 g/t, while the Gilt Creek underground resource has grown to roughly 2.5 million oz. at 3.26 g/t. A new PEA due within three months is expected to evaluate a combined open-pit/underground operation targeting 250,000–300,000 oz. per year with a larger mill, ahead of a planned prefeasibility study and 50,000-metre drill campaign.

Global tungsten producer Almonty Industries has shifted its corporate headquarters from Toronto to Dillon, Montana, aligning its base with the recently acquired Gentung-Browns Lake tungsten project, a former Union Carbide operation with existing water rights and pipework. The company, which restarted the Sangdong mine in South Korea in March after a 30-year hiatus to supply US markets, plans to recommence Gentung production as early as late 2026 using reconditioned plant from its Spanish operations, pending an extraction permit. The move follows a $90 million oversubscribed Nasdaq IPO and a $129 million follow-on financing, signalling a push to build a US-aligned tungsten supply chain outside China.

Rare Earths Americas has filed an SEC registration statement for an underwritten IPO on NYSE American under ticker “REA”, targeting heavy rare earths projects in the US and Brazil, with Cantor as lead bookrunner and Stifel as bookrunner alongside Canaccord Genuity and B. Riley Securities as co-managers. Proceeds are earmarked for land acquisition, drilling, metallurgical test work, permitting and SK-1300 technical report preparation at the Shiloh project in Georgia. Additional funds will support exploration, land consolidation, metallurgy, engineering and permitting at the Alpha and Constellation projects in Bahia and Minas Gerais, plus early-stage work at Homer and Liberty Peak.

Eriez will showcase its CavTube column flotation system at CRU Phosphates+Potash 2026, focusing on recovering ultrafine phosphates and potash from tailings streams to improve overall plant performance and water reuse. Global Product Manager – Column Flotation, Michele Tuchscherer, will present a technical paper on “Sustainable Slimes Beneficiation”, detailing how column flotation can treat slimes fractions that are typically lost to tailings. For process engineers, the pitch centres on higher ultrafines recovery, reduced tailings volumes and more efficient reagent and water utilisation in existing circuits.

Sandvik is expanding its underground ground support portfolio with fully integrated, end-to-end resin bolting solutions that combine Sandvik drill rigs, pumpable resin systems, resin capsule injection technologies, chemical products and a unified bolt range. The package is designed so drilling, resin delivery and bolt installation operate as a single system, reducing interface issues between equipment and consumables in high-stress and seismically active headings. For geotechnical and mining engineers, the move signals tighter control over bond quality, installation consistency and cycle times in resin-anchored support.

Perth will host the Global Resources Innovation Expo (GRX26) from 5–7 May, with high‑level delegations from Canada and Peru joining Australian mining and METS leaders. Co‑hosted by Austmine and AusIMM, the event will centre on mining equipment, technology and services, including digital mine optimisation, automation and decarbonisation technologies. Attendance by government and industry representatives from major copper and critical minerals jurisdictions signals strong interest in cross‑border collaboration on METS procurement, standards and technology transfer.

Turner Mining Group has secured a structured capital facility of up to $150 million from Wingspire Equipment Finance to expand its mining equipment fleet and support contract operations across North America. An initial $20 million tranche has already been deployed, with further drawdowns planned as additional haul trucks, excavators and ancillary support plant are brought online. The facility gives Turner flexibility to scale yellow iron capacity quickly on new greenfield and brownfield projects without tying up balance-sheet cash, a key consideration for high‑volume overburden and quarry stripping contracts.

A $95 million upgrade of the Mount Lindesay Highway at Jimboomba has been completed, rebuilding a 1.5‑kilometre section between Johanna Street and South Street under joint Queensland–Australian Government funding. Works included full pavement reconstruction, additional lanes and intersection upgrades to handle rapid traffic growth in one of south‑east Queensland’s fastest‑expanding corridors. For civil and geotechnical teams, the project signals continuing demand for short‑section, high‑intensity highway widening and pavement strengthening on constrained brownfield alignments.

Investigations and planning have begun for short- and long‑term upgrades to the Princes Highway through Narooma, including works on the ageing Narooma Bridge, under a joint Federal–NSW Narooma Bridge and Transport Improvements Study. The feasibility study, led by Transport for NSW Acting Executive Director Brendon James, will assess options for bridge renewal or replacement and corridor improvements to address current traffic constraints and flood resilience. Outcomes will guide future design development, staging and funding bids for this critical South Coast freight and tourism route.

Former Lafarge chief executive Bruno Lafont has been sentenced by a French court to six years in prison and the company fined more than €1m for developing what the presiding judge called a “genuine commercial partnership with IS” around its £680m Jalabiya cement plant in northern Syria. Lafarge Cement Syria was found to have paid about €5.6m to Islamic State, Jabhat al-Nusra and intermediaries to keep the plant and its supply trucks operating after 2013, when militants controlled the area. The ruling links corporate payments to militant control of local natural resources, raising acute compliance and security-risk questions for construction materials firms operating in conflict zones.

Black Cat Syndicate has reached a key milestone at its Kal East gold project, with the Lakewood processing facility now treating ore entirely from Kal East rather than toll feed. The company is ramping up throughput at Lakewood’s existing carbon-in-leach circuit while advancing underground development at the nearby Majestic and Myhree deposits. This shift to 100 per cent Kal East ore signals a transition towards steady-state production and gives geotechnical and processing teams a clearer basis for optimising stope design, dilution control and plant performance on a single ore source.

High‑grade reverse circulation drilling intercepts at New Murchison Gold’s Crown Prince East pit are building confidence ahead of open‑pit mining, with recent hits including multiple narrow high‑grade zones that extend known mineralisation down‑dip and along strike from the existing Crown Prince pit. The company has already completed the first production blast at Crown Prince, integrating the new data into short‑term mine planning and grade control for the East pit. For geotechs and mine planners, the results support pit shell optimisation, potential cut‑back designs and tighter dilution control in the early mining phase.

Perth Mint has been flagged by Western Australian Premier Roger Cook as a potential downstream processor for rare earths, expanding its current role beyond refining gold and silver at its East Perth facility. Cook is reportedly considering using the state-owned mint’s existing metallurgical expertise, secure handling infrastructure and government backing to support value-adding of locally mined rare earth concentrates. For miners, this signals possible in-state options for separation or refining, which could shorten export supply chains and change project economics for WA rare earth deposits.

Northern Territory’s annual exploration seminar in Alice Springs is promoting the region’s copper, rare earths and critical minerals potential under the NT Government’s Resourcing the Territory initiative. Officials are courting juniors and majors with co-funded drilling grants and new pre-competitive geoscience datasets, including high-resolution aeromagnetics and regional gravity surveys across underexplored basins. For geotechs and miners, the focus is on greenfields targets in Proterozoic terranes and basin-hosted systems that could support future large-scale open pit and underground developments.

Horizon Minerals has formally rebranded as Maritana Minerals after shareholder approval at an extraordinary general meeting, aligning the company identity with its Black Swan nickel project strategy in Western Australia. The move consolidates focus on the Black Swan asset near Kalgoorlie, where existing processing infrastructure and historic nickel resources are being evaluated for restart economics under current price and cost conditions. For contractors and service providers, the rebrand signals a clearer pivot from gold-centred exploration towards nickel sulphide development work around the Black Swan plant and associated underground and open-pit targets.

FI Real Estate Management has been fined £40,000 at Caernarfon magistrates court for unlawfully demolishing buildings on the Peblig Industrial Estate, Caernarfon, that contained bat roosts for three species identified in a 2023 survey. The works proceeded in September 2024 without the required European Protected Species Licence from Natural Resources Wales and before an acceptable replacement bat house design had been agreed with a senior biodiversity officer. The conviction under the Conservation of Habitats and Species Regulations 2017 and the Wildlife and Countryside Act 1981 reinforces that demolition and redevelopment programmes must integrate protected species licensing into design and sequencing.
