Historical & Operational Significance of Quebrada Blanca Copper Mine
Discovered in the Early 20th Century
Quebrada Blanca was initially discovered in the early 20th century. Mining operations began to take shape in the latter half of the century, with the first significant exploitation occurring in the 1980s using traditional open-pit methods to extract oxide copper. Over the decades, the mine evolved—from processing oxidized ore to fully embracing modern mining practices.
From Oxide Beds to Sulphide Dominance: The Transformative Phase of QB2
Following the depletion of the oxide beds in 2017, Quebrada Blanca entered a transformative phase, known as QB2, now entirely operational as of 2025. Through QB2, the mine shifted towards higher-grade sulphide deposits, enabling not just increased output but also more sustainable processing of copper, molybdenum, and silver—yielding over 300,000 tonnes of copper annually.
