How to Claim on a Metals Policy: The Claim Roadmap
A claim is the only test of an insurance policy. The metals industry has produced some of the largest insurance claims on record — Brumadinho (US$ multi-billion), Samarco (Renova Foundation US$ 10bn+; UK Group Litigation Order with ~700,000 claimants), Mount Polley, Kingston Fossil Plant TVA ash spill, Baia Mare cyanide spill — each a reference point for cause-and-origin investigation, indemnity computation, subrogation and litigation. This page distils the claim lifecycle into five phases and three switchable views: claim type, case precedent and jurisdiction. All references are primary — Lloyd's, CILA, IUMI, court judgments, Renova Foundation, GISTM, regulator findings. See also the How to Insure roadmap for the upstream side, How to Inspect for surveyor and assay procedures, and the Incidents register for the documented event log.

03Case precedents — pick a benchmark
Five reference events shape how the metals insurance market currently writes risk and handles claims. Pick a case to see what happened, what was paid, and what wording changed.
Event & loss
25 January 2019, Córrego do Feijão iron-ore mine, Brumadinho, Minas Gerais. Upstream tailings dam B-I failed by static liquefaction; 12 million m³ of tailings released; 270 fatalities. Vale's largest tailings disaster.
Settlement & cost
Vale signed a R$ 37.7bn (~US$ 7bn) Term of Adjustment of Conduct (TAC) with Minas Gerais state in Feb 2021 — at the time the largest single environmental settlement in Brazilian history. Additional civil/criminal proceedings continue.
Insurance market impact
Triggered the global TSF carve-out from Operational Mining wordings, GISTM creation (Aug 2020), Brazilian ANM Resolution 13/2019 banning new upstream-method dams and ordering decommissioning of existing ones. Many reinsurers exited TSF entirely.
Event & loss
5 November 2015, Fundão tailings dam at the Samarco Mariana complex (Vale + BHP JV) failed; ~43 million m³ of tailings released into the Rio Doce, reaching the Atlantic. 19 fatalities; ~700,000 people affected along ~650km of river.
Settlement & cost
Renova Foundation established by Samarco / Vale / BHP — initial budget R$ 24bn, since revised upward. October 2024 federal accord increased the package to R$ 170bn (~US$ 30bn) over 20 years. Parallel UK Group Litigation Order (Município de Mariana & Ors v BHP Group plc) covers ~700,000 claimants; £36bn trial started October 2024.
Insurance market impact
Reference case for cross-border class action against a UK-domiciled parent for the actions of a foreign subsidiary. UK Supreme Court ruled (2022) the claim could proceed in English courts. Triggered re-thinking of D&O Side C cover and parent-company liability exposure.
Event & loss
4 August 2014, Mount Polley copper-gold mine, British Columbia. Tailings dam breach released ~25 million m³ of water and tailings into Hazeltine Creek, Polley Lake and Quesnel Lake. No fatalities; major environmental damage; investigation found a foundation glacial-till layer was inadequately characterised.
Settlement & regulatory outcome
BC Mines Inspector report (2015), BC Auditor General audit (2016), federal Fisheries Act charges withdrawn in 2022. Imperial Metals reached a remediation agreement with the BC government. Mount Polley Mining Corp. obtained an effluent permit to resume discharges.
Insurance market impact
First major North American TSF claim in the post-IFC era. Triggered the Independent Expert Engineering Investigation and Review Panel; recommendations on best-available-technology requirements informed both the BC mining code and the GISTM standard. Reference case for foundation-characterisation due diligence.
Event & loss
22 December 2008, Kingston Fossil Plant, Tennessee. The Tennessee Valley Authority (TVA) coal-ash containment pond failed; ~4.1 million m³ of coal fly-ash slurry released into the Emory and Clinch Rivers. No immediate fatalities, but a major occupational-disease class action followed among the clean-up workers.
Settlement & precedent
2018 Tennessee jury found Jacobs Engineering Group liable to clean-up workers for failure to protect against ash exposure; subsequent multi-million-dollar settlements. The case is the leading US precedent on post-spill occupational disease liability.
Insurance market impact
Triggered EPA's first federal coal-ash rule (CCR 2015). Reference case for EIL long-tail liability and the interplay between Workers' Comp, EL and PL where a contractor's employees claim against the principal. Major US Cleanup Cost cover precedent.
Event & loss
30 January 2000, Baia Mare gold reprocessing site, Romania. A cyanide-laden tailings dam at the Aurul SA (Esmeralda Exploration / Romanian state JV) operation overflowed; ~100,000 m³ of cyanide-contaminated water entered the Lapus and Somes rivers, then the Tisza and Danube. Massive fish kill from Romania through Hungary to Yugoslavia.
Settlement & regulatory outcome
EU Mining Waste Directive 2006/21/EC was a direct response. Romania paid limited compensation; Esmeralda Exploration (Australian-listed) collapsed. The International Cyanide Management Code (ICMI) was created in 2005 — a voluntary code that is now de facto licence-to-operate for gold cyanide leach plants worldwide.
Insurance market impact
Reference case for trans-boundary pollution and the limits of EIL recovery when responsible operator is judgment-proof. Drove EU-wide hard tailings rules; ICMI Code became an underwriting condition for many gold-cyanide leach operations.
04Detailed phases
Phase 1Loss notification (0–48 hours)
The clock starts at the moment of loss. Every policy has a notification clause — typically immediate notice for material events; written notice within 24-72 hours. Late notice is the single most common defence underwriters raise against a claim. The first 48 hours are also when the cause-and-origin story can be preserved or destroyed.
- Immediate phone call to broker; broker to lead underwriter same day
- Written notice on insurer's claim form within policy window (typically 24–72 hours)
- Secure the scene — restrict access, preserve damaged plant, freeze CCTV and SCADA logs
- Internal communications protocol — privileged channels for legal & risk; controlled external comms
- Regulator notifications — mining inspector, environmental agency, mine-safety regulator (ANM, MSHA, DMIRS, ICMM members)
- Mandatory disclosures — stock exchange (listed companies), debt covenants, project-finance lender notifications
- Crisis-management consultant on standby (especially for K&R and reputational events)
Phase 2Evidence preservation (0–4 weeks)
Evidence preservation is what wins or loses the indemnity argument. The insurer's loss adjuster will arrive within days (often within 24 hours for major events) — the insured must already have the scene secured, photographed and logged. For TSF and mine-incident claims the regulator's investigation runs in parallel, and the insured does not control its timetable.
- Site security perimeter; access log; chain of custody for damaged components
- Photographic / video survey before any clean-up; drone aerial survey for site-scale events
- Witness statements taken under legal privilege wherever possible
- Electronic evidence — SCADA logs, dispatch system, CCTV, mine plan, geotechnical monitoring data — preserved with hash and chain-of-custody log
- Cause-and-origin samples — failed components retained for forensic engineer; soil/water samples for environmental events
- Regulator co-operation — provide requested data but co-ordinated through legal; never speculate on cause
- Document retention hold across all relevant systems
Phase 3Adjustment & investigation (3–18 months)
The loss adjuster — appointed by the insurer but professionally independent — investigates cause, quantum and coverage. For mining and TSF events a forensic engineer (geotechnical, fire, marine or specialist) leads the cause-and-origin work; for cargo claims a marine surveyor runs the outturn process. The adjuster issues an interim report ~30 days in, then progress reports through to a draft final report.
- Adjuster appointment — typically Crawford, Sedgwick, McLarens, Charles Taylor, RGL, or specialist mining adjusters (e.g. International Mining Consultants)
- Forensic engineer scope agreed — independent of operator's own engineer
- Reserve setting — initial reserve conservative; revised quarterly as facts emerge
- Payment on account — where indemnity is not in dispute, partial payments preserve insured's liquidity
- Coverage analysis — proximate cause, fortuity, indemnity principle, sub-limit application, deductible mechanics
- BI calculation — gross profit forecast vs actual; Increased Cost of Working; Maximum Indemnity Period; mitigation expense
- Salvage & mitigation — recoverable equipment, scrap value, contractor mobilisation, alternative supply arrangements
Phase 4Indemnity computation & negotiation (3–24 months)
Indemnity is the policy promise: put the insured back in the position they would have been but for the loss, no better and no worse. Quantum disputes are resolved by negotiation, mediation, expert determination, arbitration or court. Bermuda Form arbitration is the standard for large excess casualty placements; Lloyd's slip wording specifies London arbitration or English courts as default.
- Final adjuster report — agreed loss, allocated by section and sub-limit
- Indemnity = Loss − Deductible − Sub-limit cap − Underinsurance penalty (if average applies)
- BI = (Forecast Gross Profit − Actual Gross Profit + Increased Cost of Working) over Indemnity Period
- Mitigation expense — recoverable where reasonable; salvage credited against indemnity
- Coverage disputes — escalate via mediation, Bermuda Form arbitration, or English High Court (Lloyd's default)
- Settlement & release — payment, full and final release, with or without subrogation reservation
- Tax — indemnity payments structured to track tax treatment of underlying loss (capex vs opex)
Phase 5Subrogation & litigation (12–60 months)
Once paid, the insurer is subrogated into the insured's rights against any responsible third party. For cargo claims that is the carrier (subject to Hague-Visby package limits, CMR liability limits, COTIF/CIM limits); for CAR/EAR claims it is the contractor or designer; for environmental claims it can be a supplier of defective equipment. Subrogation actions can run 3–5 years from settlement. Criminal proceedings are independent of insurance recovery and are not insurable in most jurisdictions.
- Subrogation rights preserved by reservation in release; insurer takes assignment
- Carrier liability (Hague-Visby, CMR, COTIF) — limitation-based; usually leaves residual loss on insurer
- Contract chain — designer, contractor, sub-contractor; project-warranty period;back-to-back liability
- Class actions / Group Litigation Orders — defended in parallel; D&O Side C responds
- Regulator enforcement — administrative fines (uninsurable in most jurisdictions); civil penalties
- Criminal proceedings — uninsurable; insurance pays defence costs only to point of conviction
- Reserve commutation — insurer closes the claim file when IBNR exhausted
05Reference doctrines & principles
Proximate cause
The dominant cause of loss — not necessarily the first or last in the chain. Coverage triggers on whether the proximate cause is an insured peril. Established in Leyland Shipping v Norwich Union [1918]; still the foundational test for cargo and property claims worldwide.
Indemnity principle
The insured cannot profit from a loss — restored to pre-loss position, no better, no worse. Codified for marine in Marine Insurance Act 1906 s.1. Reinforced by averaging clauses where insured value is below replacement cost.
Fortuity
Cover responds only to a fortuitous event — not to certainty, inevitability or pre-existing condition. Wear-and-tear, gradual corrosion and inherent vice are excluded by this doctrine even where not expressly listed.
Utmost good faith (uberrimae fidei)
Mutual duty of disclosure between insured and insurer. UK Insurance Act 2015 codified the modern test: the insured must make a "fair presentation of risk". Material non-disclosure entitles the insurer to remedies graduated by intent (innocent / negligent / deliberate).
Subrogation
The insurer steps into the insured's shoes against responsible third parties — to the extent of payment, not beyond. Cannot pursue the insured itself for the same loss (anti-circuity). For cargo claims, the marine clauses typically transfer subrogation rights by endorsement at policy inception.
Contribution
Where two or more policies cover the same loss, they contribute rateably (by limits or by losses, depending on wording). Critical in Stock Throughput / Marine Cargo overlap and CAR/PAR overlap during commissioning. "Other insurance" clauses determine the order of response.
