    Centerra Langeloth explosion: process safety and moly supply notes for engineers

    Centerra Langeloth explosion: process safety and moly supply notes for engineers

    First reported on MINING.com

    30 Second Briefing

    Centerra Gold has suspended operations at its Langeloth metallurgical facility in Pennsylvania after an uncontrolled mixture of chemicals triggered an uncontained reaction adjacent to the acid plant at about 6:15 p.m. Eastern on Thursday. Two contractors were hospitalised with injuries and two employees taken to hospital as a precaution, with Centerra reporting no significant environmental release and confirming regulators have been notified. The shutdown hits Centerra’s key downstream plant for molybdenum concentrate, slated to process output from the Thompson Creek mine in Idaho when it restarts next year.

    Technical Brief

    • Incident reinforces the need for rigorous process safety management around acid plants, including HAZOP refresh and contractor-permit controls.

    Our Take

    Centerra Gold already features heavily in our recent Canada-focused coverage through the Kemess and Mount Milligan copper-gold assets in British Columbia, so a safety incident at the Langeloth metallurgical facility in Pennsylvania adds cross-border operational risk considerations for lenders and insurers looking at the group’s North American portfolio.

    Because Langeloth processes molybdenum and Centerra has recently taken a 9.9% equity stake in molybdenum-exposed junior Metal Energy, any prolonged disruption at the facility could complicate how investors value Centerra’s broader moly strategy rather than just its gold-copper mine pipeline.

    The 8% share-price reaction on a C$4.8 billion market value underscores how safety and processing-plant reliability are being priced into Centerra’s M&A legacy assets like Thompson Creek Metals, which contrasts with more growth-oriented sentiment seen around its Kemess PEA and Mount Milligan life-extension approvals in British Columbia.

    Modern Mining’s US e-waste expansion: process, recovery and supply notes for engineers

    Modern Mining is preparing to commercialise its Greenville, North Carolina e-waste plant, which shreds, gravity-separates and then uses “aqueous purification” chemistry to recover gold, silver, palladium and copper without large-scale incineration or new smelting capacity. The move comes as President Trump’s July use of the Defense Production Act enables export restrictions on industrial waste containing critical minerals, aiming to keep higher-than-ore-grade electronic scrap within US borders. Modern Mining plans a distributed network of modular plants—targeting roughly one new facility per year over five years—to build a domestic secondary-metals supply chain alongside conventional mining.

    Gold price shakes off profit taking: planning signals for mine project teams

    Gold for December delivery on Comex rose 0.3% to $4,435/oz after rebounding from $4,365.50 and nearing $4,454.60 intraday, as softer July US inflation cut money-market odds of a September Fed hike to about one in three from over 40% a week earlier. Spot gold steadied around $4,353/oz and silver futures at $65.13/oz left silver down about 8% year-to-date, while BMI now expects gold to average $4,400/oz in 2026 with the dollar index in a 98–102 range. Precious metals miners have surged, with Hecla, Eldorado, Equinox, Coeur, Agnico Eagle and Newmont up 26–32% over ten sessions against an 8% move in gold.

    Copper price near record: LME warehouse squeeze and project signals for engineers

    Copper is trading near a record $14,500/t as the LME August contract’s premium over September blows out to $370/t and cash-to-three-month spreads hit $434/t amid a 42-day drawdown in exchange stocks to 204,975 t, nearly half already earmarked for withdrawal. Traders are diverting metal to the US ahead of potential 15–30% tariffs on refined copper and to China as smelters cut output following the DRC’s concentrate export ban, while Chilean supply remains constrained around 5.5 Mt/y and Indonesia’s 342,000 t/y Gresik smelter is offline. BMI now pegs 2026 prices near $13,500/t with “strong upside risks”, as shorts on the LME face the prospect of a warehouse bidding war.
