The Los Bronces mine is a large copper mine located in central Chile, on the border of the Santiago Metropolitan Region and the Valparaíso Region. The processing plant is located at 3,300 m above sea level, with mining operations extending up to 4200 m above sea level. Los Bronces represents one of the largest copper reserves in Chile and in the world having estimated reserves of 3.13 billion tonnes of ore grading 0.32% copper.{{cite web|url=http://www.angloamerican.com/~/media/Files/A/Anglo-American-Plc/media/fact_book/copper_2012|title=Copper mines|year=2011|publisher=angloamerican.com|accessdate=2013-07-06|archive-url=https://web.archive.org/web/20130202103617/http://www.angloamerican.com/~/media/Files/A/Anglo-American-Plc/media/fact_book/copper_2012|archive-date=2013-02-02|url-status=dead}}
Mineralization at Los Bronces is thought to be due to its position at the intersection of two large fault systems. This favoured the rise of magma and the subsequent circulation of mineral-rich fluids.{{cite journal |last1=Piquer Romo |first1=José Meulen |last2=Yáñez |first2=Gonzálo |last3=Rivera |first3=Orlando |last4=Cooke |first4=David |date=2019 |title=Long-lived crustal damage zones associated with fault intersections in the high Andes of Central Chile |url=http://www.andeangeology.cl/index.php/revista1/article/view/V46n2-3106/pdf |journal=Andean Geology |volume=46 |issue=2 |pages=223–239 |doi=10.5027/andgeoV46n2-3108 |access-date=June 9, 2019|doi-access=free }}
