Expansion of Toromocho copper mine in Peru begins

June 4, 2018

Chinalco, also known as Aluminum Corp of China, began work on its $1.3 billion expansion of its Toromocho copper mine in central Peru. 

Reuters reported that the investment will increase the mine’s copper output by 45 percent by 2020, with the value of production exceeding $2 billion annually, Chinalco Chairman Ge Honglin said at a groundbreaking ceremony in Peruvian capital Lima, according to a company statement.

The statement gave no tonnage figures, but China’s official Xinhua news agency said Chinalco wanted the expansion to take Toromocho’s copper concentrate processing capacity to 157 kt/day (175,000 stpd) and annual refined copper output to 300 kt (330,000 st).

China is the world’s biggest copper consumer, while Peru is the second-biggest producer of the metal after South American neighbour Chile.
Chinalco is China’s largest state-owned aluminium producer but also has some copper assets, including in China’s southwestern Yunnan province.

It took control of Toromocho in 2007, bringing the project on stream in late 2013. The company had agreed a preliminary deal in November 2016 to take the development into a second phase through the $1.3 billion expansion.

The project, which is mined for silver and molybdenum as well as copper, contains 1.526 Gt (1.68 billion st) of ore, according to Chinalco’s local unit Minera Chinalco Peru. The average copper content is 0.48 percent.
