The General Mining Directorate of Peru’s Ministry of Energy and Mines (MINEM) has given the green light to the expected plant expansion at the Toromocho copper mine.

Chinalco, owner of the mine, had approved the second phase of Toromocho’s expansion in 2018, but delays in obtaining official permits and the COVID-19 pandemic postponed the completion of the initiative, which amounts to a $1.35 billion capital investment. The project would grow the plant’s capacity from 140,000 tons per day (t/d) to 170,000 t/d through the construction and installation of auxiliary equipment.

Toromocho is ranked among the five largest copper producers in Peru. It produced more than 244,000 tons of copper in 2022.
