Chinalco gets OK to partially restart Peru copper mine

• Chinese-owned mining company Minera Chinalco (ACH +1.2%) says it received a go-ahead from Peru's government to partially restart operations at its Toromocho copper mine, which were halted last week due to environmental contamination.
• ACH opened the open-pit mine late last year, becoming the first mine in Latin America set up from scratch by a Chinese company; the mine's estimated production is 1M tons/year of copper concentrate.
