Mas Errázuriz, the mining and infrastructure engineering and construction company with more than forty years of experience in Chile and twenty in Peru, continues to establish itself as the leading company in the region in the construction of underground works. In its years of experience, Mas Errázuriz has executed projects for the most important mining companies in the region, providing services for the development and exploitation of underground mines and the construction of civil tunnels, and has accumulated more than 500 km of tunnels executed since its inception.
Mas Errázuriz is recognized for its extensive technical capacity, high safety standards, human talent, commitment and, above all, the quality of all the projects it carries out. In recent years, the company has established itself in the region as a leader in the execution of underground works.
In Peru, the Asana River diversion tunnel for Anglo American’s Quellaveco mine, the most important mining project under construction in the country, stands out. It also highlights two contracts in execution for the Antamina Mining Company, one of the largest mining companies in Peru. These are two works in parallel: the construction of the MCD tunnel and the extension of the decantation tunnel.
In this way, Mas Errázuriz has shown, both in its work in Peru and in other parts of the region, to be a construction company that offers a world-class service and that executes large-scale projects with added value in each of them.
