LIMA, March 11 (Reuters) – Peru on Wednesday approved an environmental study for Buenaventura, one of Peru’s ​largest mining firms, to proceed with ‌its southern Trapiche copper project with an estimated investment of $3.4 billion, the Andean nation’s state certification office said. The environmental certification ‌office ​SENACE said the evaluation ⁠of the detailed ⁠environmental impact study “guarantees the development of activities under high sustainability standards” in Peru’s Apurimac region.

SENACE noted that ​while the study’s approval is an essential step, it does not ⁠in itself authorize ⁠the miner to begin operations.

Peru ​is the world’s third-largest copper producer. ​Regulators in the South American country ‌require other permits including a construction license before miners can begin extracting ore.

Executives at Buenaventura, which owns ⁠several gold and silver mines across the country, have said Trapiche should become one ⁠of the ‌company’s most important copper ⁠projects when it becomes operational ​after ‌2030.

Buenaventura also owns close ​to 20% ⁠of Cerro Verde, one of Peru’s largest copper deposits. The mine there is run by U.S.-based miner Freeport McMoRan.
