Caserones is a low-grade copper and molybdenum mine in Tierra Amarilla in Atacama Region, Chile. The mine is operated by SCM Minera Lumina Copper Chile, a joint venture where Lundin Mining have 70% of the shares and JX Nippon Mining & Metals owns the remaining. The mine lies about 4,000 m a.s.l. in the Andes and just about six kilometers west of the Argentina–Chile border.
Construction of the mine started in 2010 and it begun operations in 2014.[1] Mining is expected to last until 2042 according to the mining plan.[2] An environmental impact assessment to modify the previously approved mining project was submitted in 2020 and approved by authorities in July 2025.[3]
Originally, JX Nippon Mining & Metals owned 51.5% of the mine and Mitsui Mining and Smelting owned 25.87% and Mitsui & Co. 22.63%.[1] Later JX Nippon Mining & Metals acquired a 100% ownership of the mine before selling 51% of the shares to Lundin Mining in March 2023.[1][4] The sale to Lundin Mining included an option for a further purchasing of 19% in the next five years, an option which Lundin Mining took on July 2024.[5]
