    Benz’s Glenburgh tungsten corridor: mine layout and ground risk notes for engineers

    Benz Mining has confirmed widespread tungsten mineralisation along the full 12km Glenburgh corridor in Western Australia, indicating a large-scale skarn and vein-style system associated with the region’s granitic intrusives. Early drilling and surface sampling show continuous scheelite-bearing zones over multiple kilometres, with several prospects already returning high-grade intervals suitable for hard-rock tungsten concentrate production. For geotechnical and mine planning teams, the corridor-scale continuity suggests potential for multiple open pits or a combined pit–underground layout, with significant focus needed on ground support in brittle, altered host rocks.

    Terrafame Sotkamo scandium recovery: process integration notes for engineers

    Terrafame has started a prefeasibility study to recover scandium from process streams at its bioheap-leach nickel mine in Sotkamo, Finland, using the existing hydrometallurgical circuit as a base. If viable, the project would make Terrafame the only scandium producer in Europe, adding a critical rare earth element to its current battery-grade nickel output. For process engineers, the key questions will be scandium grades in intermediate liquors, additional solvent extraction or ion-exchange stages required, and integration without disrupting nickel and cobalt recovery.

    Recovering more metal from leach pads: irrigation design notes for mine engineers

    Recovering more metal from existing heap leach pads, rather than building new mines, is presented as mining’s fastest production gain amid IEA-forecast supply gaps of 30% for copper and 40% for lithium by 2035. Tom Claridge, sales manager for Mining North at Netafim North America, argues that uneven solution distribution caused by slope, rock size, line spacing and pressure inconsistencies creates persistent wet–dry zones and permanent metal loss. He points to precision irrigation systems with controlled pressure and flow, plus automated monitoring, as key to improving percolation, water use and predictability on large pads.

    Sigma Lithium Brazil ruling: waste pile stability lessons for mine engineers

    Sigma Lithium is appealing a 17 May ruling by a local judge in Araçuaí that could impose up to $10 million in legal collateral over alleged improper waste disposal at its Grota do Cirilo lithium operation, after the case triggered a 15% share slide to about $14.50 and a $2.6 billion market capitalisation. Brazilian labour inspectors reportedly cited continued dumping on one of three suspended waste piles and a “partial rupture” near a school in Poço Dantas, raising structural and geotechnical stability concerns. The dispute coincides with Sigma’s plan to expand Grota do Cirilo from 270,000 to 520,000 tonnes per year of lithium concentrate, signalling tighter scrutiny of waste pile design, monitoring and closure in Latin American lithium projects.

    Cerrejón closure push on Glencore: transition and risk takeaways for mine planners

    Colombia is pressing Glencore to start detailed closure and transition planning for the Cerrejón complex, a 16.8‑million‑tonne‑per‑year open‑pit coal mine with a 150 km dedicated railway and Caribbean export port whose concession runs to 2034. A GEM consultancy report warns that abrupt, politically driven curtailment could destabilise La Guajira’s coal‑dependent economy, which currently relies on more than 12,000 mine‑related jobs, about $166 million a year in royalties and roughly $86 million in local procurement. GEM proposes a “managed transition compact” with ring‑fenced closure and retraining funds, supplier‑conversion schemes, environmental assurance financing and long‑term reuse plans for rail and port infrastructure.

    Sherritt drops plan to dissolve Cuban assets: sanctions risk lens for mine planners

    Sherritt International has reversed its plan to dissolve its Cuban mining assets, retaining its 50/50 Moa nickel-cobalt joint venture with state-owned General Nickel Company but keeping operations suspended under expanded US sanctions. The Trump executive order targeting non-US entities active in Cuba had already triggered the exit of three directors and the CFO, a share price collapse to C$0.11 and a market capitalisation of about C$81 million. Sherritt says it is assessing a preliminary “value preserving opportunity” while working with advisers and governments on a path through the sanctions.

    Jeff Currie’s $10,000 gold call: cycle, capex and price risks for mine planners

    Gold may retreat from about $4,500/oz. towards $4,000/oz. as Jeffrey Currie, former Goldman Sachs commodities chief and now Abaxx Markets executive co-chairman, stays tactically short, citing forced central bank sales such as Turkey’s roughly 120 tonnes of disposals to fund higher energy costs. Currie still targets a long-term move towards $10,000/oz., arguing that once central banks turn dovish after an energy-driven growth shock, the trade “resets”. He links this to a broader commodity super cycle driven by capex starvation and an estimated $820 billion of 2026 spending by the “Magnificent 7 plus Oracle”.

    Safeguarding conveyor performance: proactive maintenance lessons for mine engineers

    Safeguarding conveyor performance in mining and mineral processing, MATO Products sales engineer Keletso Mabula advocates comprehensive conveyor assessments focused on belt cleaners, carryback control and component wear. Proactive inspection of scraper alignment, blade tension, spillage patterns and chute loading conditions is positioned as essential to sustaining throughput and reducing unplanned stoppages on high‑tonnage overland and plant conveyors. The approach emphasises structured condition monitoring and timely maintenance interventions rather than reactive repairs once belt mistracking, excessive dust or material build-up have already escalated.

    EU ban on Russian uranium: supply and contract outlook for mine planners

    Mounting EU pressure to phase out Russian uranium and fuel services, which still provide about 25% of the bloc’s enrichment via Rosatom’s 43% share of global capacity, is pushing utilities towards Canadian supply, with Canada already covering more than 30% of EU uranium imports in 2024. Cameco, owner of 49% of Westinghouse, is positioned to capture long-term contracts as AP1000 reactor projects advance in Poland and Bulgaria and VVER units in Finland, Bulgaria, Slovakia and Ukraine convert to Western fuel. Analysts warn, however, that replacing Russian enrichment could take up to a decade due to limited Western capacity.
