    BHP Brazil dam collapse ruling: tailings design and liability lessons for engineers

    BHP Brazil dam collapse ruling: tailings design and liability lessons for engineers

    First reported on New Civil Engineer

    30 Second Briefing

    The UK High Court has found BHP Group liable for the 2015 failure of the Fundão tailings dam in Mariana, Brazil, which killed 19 people and polluted around 600km of the Rio Doce and coastal waterways. The ruling concerns the collapse of an upstream tailings structure jointly owned via Samarco, which released tens of millions of cubic metres of iron ore waste and devastated multiple downstream communities. The judgment opens the door to large-scale civil claims in England, sharpening scrutiny of tailings design, monitoring and governance for UK-listed miners operating overseas.

    Technical Brief

    • Legal findings scrutinise corporate oversight of tailings design, operation and risk management across multinational ownership structures.
    • Investigation workstreams have centred on failure mode analysis of upstream raises, liquefaction susceptibility and operational controls.
    • Post-failure monitoring has focused on downstream contamination pathways, sediment transport and long-term water quality impacts.
    • Remediation programmes must address stabilisation of remaining deposits, riverine sediment management and progressive ecosystem recovery.
    • For tailings facilities globally, upstream designs now face tighter scrutiny, with stronger expectations on independent review and disclosure.

    Our Take

    Within the 22 Failure/Safety-tagged pieces in our database, this is one of the few involving a UK-headquartered major like BHP Group, signalling that legal and ESG scrutiny is now extending more visibly to top-tier diversified miners rather than just local operators.

    The contamination of roughly 600 km of Brazilian waterways means any subsequent BHP Group tailings or water-management designs will likely face tougher permitting and independent review in Brazil and other host countries, with regulators using this case as a benchmark for ‘worst credible’ failure scenarios.

    For UK- and Australia-based mining engineers, a High Court liability finding tied to an overseas failure increases the practical importance of aligning design, monitoring and emergency planning not only with host-country codes but also with UK/Australian corporate governance and due-diligence standards.

    US $500m cobalt tender reopened: strategic supply signals for mine planners

    The US Defense Logistics Agency has reopened a $500 million tender to buy up to 7,500 tonnes of cobalt after benchmark prices more than tripled since mid-August. The agency first sought offers in August but is now reissuing the procurement as spot market volatility and tight supply complicate long-term contracting. For miners and refiners, the move signals sustained US strategic demand for cobalt metal and intermediates, with potential upside for projects able to deliver secure, traceable supply into government stockpiles.

    Ivanhoe–Qatar critical minerals push in Africa: project finance lens for engineers

    Ivanhoe Mines has signed a memorandum of understanding with the Qatar Investment Authority under which Qatar’s sovereign wealth fund will back Ivanhoe’s management in pursuing existing and new critical minerals projects in Africa. The collaboration targets large-scale copper, nickel and other battery-metal deposits across Ivanhoe’s pipeline, building on assets such as Kamoa-Kakula in the DRC. For engineers and project developers, the deal signals potential acceleration of feasibility studies, project financing and infrastructure build-out on African critical minerals hubs.

    Antimony’s “perfect storm” at Hillgrove: design and flowsheet notes for mine planners

    High-grade tungsten mineralisation has been intersected at Larvotto Resources’ Hillgrove project in New South Wales, adding a second critical metal to a site already known for antimony. Managing director Ron Heeks describes antimony as caught in a “perfect storm” of falling global mine output and rapidly rising demand from defence and energy-storage sectors, positioning Hillgrove’s combined antimony–tungsten potential as strategically significant. For mine planners and metallurgists, the find raises questions on future polymetallic flowsheet design and prioritisation of drilling to define tungsten resources alongside existing antimony targets.
