Anglo American, through its 50.1%-owned subsidiary, Anglo American Sur S.A. (AAS), and Codelco announced on Wednesday they had completed an agreement to implement a joint mine plan for their respective Los Bronces and Andina copper mines in Chile. The country is the world’s top producer of copper, accounting for about 24% of global output.

Anglo American said implementation of the joint mine plan remains conditional on securing the relevant environmental permits, along with other customary conditions for final implementation, which is currently expected by 2030.

A month ago, uncertainty arose regarding one of the world’s biggest copper operations when the Chilean environmental court annulled a permit for a desalination plant on the $3.2 billion expansion of the Collahuasi copper mine, citing concerns over impacts on indigenous communities and the marine environment. Collahuasi is jointly owned by Anglo American and Glencore.
