Hudbay Peru copper mine faces temporary shutdown amid social unrest

Hudbay Peru copper mine

Hudbay Peru copper mine operations have been temporarily disrupted by nationwide unrest and local protests in the southern mining corridor. The Hudbay Peru copper mine suspended milling at Constancia after road blockades and demonstrations escalated into security risks. As a result, the company has demobilised non-essential staff while using the shutdown to advance planned maintenance work.

Protests disrupt Peru’s southern mining corridor

Peru’s informal miners have intensified protests over stricter permit rules, repeatedly blocking strategic transport routes. These routes are vital for large producers in the southern mining corridor, including the Hudbay Peru copper mine at Constancia. Meanwhile, riots in Lima and demonstrations near the site heightened safety concerns and forced the temporary halt in milling operations.

However, Hudbay is trying to turn the disruption into an operational opportunity. The company plans to use the downtime for preventative maintenance and to pull forward scheduled work originally planned for later in the year. This approach aims to minimise future interruptions once the Hudbay Peru copper mine resumes normal throughput.

Production guidance remains intact despite Constancia halt

Hudbay has stressed that the temporary suspension should not derail its 2025 output targets. The company continues to reaffirm its copper production guidance of 117,000–149,000t for the year, despite the pause at Constancia. As a result, investors and customers are being reassured that the disruption is manageable rather than structural.

Constancia has operated since 2014 and remains one of Peru’s key copper assets. Therefore, any downtime at the Hudbay Peru copper mine is closely watched by global copper markets. Yet the company’s signal that guidance remains unchanged suggests that ore stockpiles, flexible scheduling and maintenance planning are cushioning short-term impacts.

Hudbay is also engaging with government and legal authorities to help resolve the unrest. In the near term, the stability of the southern mining corridor will depend on how quickly authorities can defuse conflict with informal miners. As a result, the risk profile for Peru’s wider copper sector remains elevated, even if Constancia’s immediate production outlook appears secure.

Constancia’s brief halt is another reminder that social licence, not geology, often dictates copper supply risk. If Peru cannot stabilise its permitting and informal mining framework, financing costs for future greenfield projects may rise. For now, Hudbay’s maintained guidance signals resilience, but repeated disruptions could eventually tighten the global copper balance.
