STRABAG subsidiary ZÜBLIN has secured two strategic contracts with Codelco for the Chuquicamata Underground Mine ‘Mina Norte,’ marking one of the company’s largest mining projects to date in Chile. The initiative is part of the transformation of Chuquicamata, the world’s largest open-pit copper mine, into a modern, long-term underground operation, with completion scheduled for 2031.
The contracts encompass the development of over 54 kilometres of tunnels and associated critical infrastructure, aimed at extending the mine’s operational life for several decades while significantly improving its environmental performance. The project will mobilise approximately 1,200 workers and will contribute to one of the largest mining construction projects currently underway in Chile.
ZÜBLIN has been successfully active in Chile for nearly four decades, delivering major mining and tunnelling projects as well as energy infrastructure. Mina Norte will further strengthen its role as a trusted partner in large-scale mining and enhance its presence in markets outside Europe.
Siegfried Wanker, STRABAG SE Management Board Member responsible for the International + Special Divisions segment: “With nearly 40 years of continuous presence in Chile and direct involvement in major projects such as Chuquicamata, El Teniente, and Candelaria, the STRABAG group has made a lasting contribution to the country’s most important mining districts. To date, the company has delivered projects in Chile worth over €6 billion, supported by a track record spanning more than 380 kilometres of tunnels and the transport of several hundred million tonnes of excavation material.”
ZÜBLIN says it is considered a trusted partner to several leading mining companies, recognised for its long-standing experience, high-quality execution, and technical and operational excellence. This strength is reflected in the rapid delivery of complex projects. Under the Chuquicamata Subterránea contract (2016–2024), the company constructed up to 1,900 metres of tunnels per month.
