Antofagasta Minerals' Antucoya hits 32Mt target
The Antucoya copper mine of Chile’s Antofagasta Minerals achieved its goal of processing 32Mt last year.
"This milestone allows us to continue demonstrating that it is possible to develop low-grade mining, efficiently and sustainably," Leonardo González, Minera Antucoya's general manager said in a statement on Tuesday.
The average grade of the open pit mine in northern Antofagasta region is 0.35%, the company added.
Antucoya, which began full production in 2017, belongs 70% to the Luksic group’s Antofagasta Minerals and 30% to Marubeni Corp.
In 2021 it produced 78,233t of copper cathodes, and in 2H22 36,400t, according to the company.
Antucoya operates with desalinated water, uses only renewable energy, and has been recognized with The Copper Mark for responsible mining.
