Glencore’s Cerrejón restart: blockade risks and planning notes for mine engineers
Reviewed by Joe Ashwell

30 Second Briefing
Glencore’s Cerrejón coal complex in La Guajira, Colombia has restarted after a 10‑day rail blockade to Port Bolivar forced a full shutdown and force majeure, with operations resuming at 18:00 on 2 June once critical supplies were restored. The mine has already faced nearly 80 blockades this year and recorded 333 in 2024—equating to 135 lost operating days—contributing to a 12% year‑on‑year drop in 2024 output to 16.8 Mt and plans to cut a further 5–10 Mt/y amid Atlantic market oversupply. Persistent community‑driven rail disruptions and uncertainty over a temporary 1% export tax are now central design and risk factors for mine planning, logistics resilience and investment decisions across Colombia’s coal sector.
Technical Brief
- Port Bolivar is Cerrejón’s sole export outlet, so any rail disruption immediately severs all seaborne shipments.
- Force majeure was lifted and restart initiated precisely at 18:00 on 2 June, once critical inventories recovered.
- The 10‑day blockade specifically choked inbound deliveries required for both mine production and port export operations.
- Cerrejón is described as one of the world’s largest open‑pit coal mines and a key Atlantic supplier.
- In 2023, 201 blockades plus nine terrorist attacks halted coal transport for a cumulative 95 days.
- By contrast, 333 blockades in 2024 translated into 135 days of interrupted operations, indicating escalation in frequency and duration.
- Company statements emphasise staged reactivation with explicit safety conditions for personnel, environment and operating assets.
- Despite election‑driven optimism on resource policy, unresolved community‑infrastructure disputes along the rail corridor remain a dominant operational risk driver.
Our Take
Colombia’s push for detailed closure and transition planning at the Cerrejón complex, noted in the 19 May article, means repeated rail blockades in La Guajira are likely to strengthen arguments in Bogotá for accelerating the wind‑down of thermal coal in favour of other commodities such as copper and lithium mentioned in current policy debates.
With 135 days of interrupted operations in 2024 and a planned 5–10 Mt annual output reduction at Cerrejón, Glencore’s Colombian coal exposure is becoming structurally less reliable, which may increase the strategic value of its copper and critical minerals positions highlighted in other recent Glencore‑tagged coverage.
