OHLA expands its portfolio in the Chilean mining sector with its participation in a 130 million euro contract
OHLA expands its portfolio in Chile with the participation in a 130 million euro contract for the height extension and construction of walls of the tailings deposit of Minera Spence, in the municipality of Sierra Gorda, Antofagasta region. This project, which is part of the new expansion phase of the deposit, will be developed in consortium with the companies Besalco and Valko, and will complement other activities previously developed at the facilities, owned by BHP, the world’s largest mining company.
The works of this new phase include the excavation, processing and backfilling of earth to permeate the main wall and the northeast starting wall, the construction of drainage and infiltration interceptor ditches, as well as the construction of berms and the protective embankment. The operation is located 162 km from Antofagasta and 69 km from Calama, at an altitude of 1,750 meters above sea level.
This initiative joins others developed by OHLA in the country’s mining sector, such as the development of a copper treatment plant and the maintenance of the roasting complex, both for the Ministro Hales Division; the expansion project of the Talabre Dam, a tailings dam located in the Chilean city of Calama; or the work achieved in the world’s largest subway copper deposit, the El Teniente mine. The company has also carried out crushing and transport of rhyolite at the Minera Escondida plant, near Antofagasta, and has carried out important hydraulic works such as the Chacrillas reservoir in San Felipe.

OHLA has been developing infrastructure in Chile for more than four decades, where it has developed projects such as the construction and management of the Justice Center or the construction of eight hospitals with more than 2,865 beds and more than 418,000 square meters.
