What is Codelco's role in copper and lithium mining?

Codelco is a Chilean state-owned mining company and one of the largest copper producers in the world, generating a significant share of state revenues. Following Chile's National Lithium Strategy, the company has also ventured into lithium brine extraction through strategic joint ventures. Despite its prominent position, Codelco's copper production has faced stagnation and decline due to geomechanical challenges in several of its primary mines.

What we know

• Codelco is a Chilean state-owned mining company formed in 1976 from nationalised foreign-owned copper companies, and it ranks among the world's leading copper producers. [3]
• State-owned Codelco alone generated 2.6% of the Chilean state's revenue in 2020. [2]
• Following the 2023 National Lithium Strategy, Codelco entered lithium mining by forming joint ventures to take over operations in the Salar de Atacama and partner in the Salar de Maricunga. [3]
• Codelco's copper production has declined since 2004, with a notable drop between 2021 and 2023 driven by geomechanical problems affecting mines such as El Teniente, Chuquicamata, and Ministro Hales. [3]

Still open

• The exact economic viability of Codelco's additional identified resources of 208 million tonnes of copper remains uncertain.
