El Teniente

El Teniente is an underground copper mine located in the Andes mountains near Rancagua in central Chile. It is operated by Codelco, the Chilean state-owned mining company, and is one of the largest copper mines in the world by reserves and production. The mine has been in continuous operation since the late nineteenth century, making it one of the oldest active copper mines globally. El Teniente produces several hundred thousand tonnes of copper a year, contributing significantly to Chile's position as the world's leading copper producer. The orebody lies at high altitude and the mine extends over multiple levels underground, with a complex network of tunnels and shafts. Copper from El Teniente is refined and exported for use in electrical wiring, construction, electronics and renewable energy infrastructure. The mine is a major employer in the O'Higgins Region and plays a central role in the local and national economy. Codelco has invested in modernisation and expansion projects at El Teniente to extend its operational life and maintain output levels. The facility is strategically important to global copper supply, particularly as demand rises for the energy transition and electric vehicles.
