Following its acquisition of mining rights to the Caserones copper deposit in 2006, JX Metals conducted feasibility studies and undertook stripping and construction. In 2013, production of refined copper using the SX-EW method was begun and full-scale copper concentrate production commenced in May 2014. The Caserones Copper Mine is situated in a steep location at an altitude of more than 4,000 meters and the difficulties this causes have been overcome while also facing challenges such as weather problems and the COVID-19 pandemic. Recently, with the achievement of stable operation, productivity has been further improved and the mine reached a cumulative production volume of one million tons (copper content) in November 2022. Up to today, while maintaining cooperative and open relationships with neighboring communities, it has contributed greatly to the vitalization of the local economy through the creation of employment.
