In late December 2023, when communities in the southeastern Peruvian province of Cotabambas received a copy of proposed modifications to the Las Bambas copper mine, they were at first surprised, and then frustrated. The document, which arrived between Christmas and New Year’s, contained a proposal to almost double the mining operation but lacked detailed studies on its environmental impact on aquifers, wetlands and rivers, which are crucial to the communities. Yet, they were given mere weeks to send in comments. In response, around a dozen organizations sent a letter to the agency of environmental certification for sustainable investment (SENACE), requesting they annul the amendment. “They didn’t consult with us at all, they only sent notifications,” said Walter Contreras, a local leader of the Cotabambas Defense Front, one of several organizations that signed the letter. It was impossible to infer from the document what exactly the impacts were going to be for communities like his, which are directly in the mine’s impact zone. The open-pit mine of Las Bambas sits at 4,000 meters (13,100 feet) above sea level. It is one of the largest copper mines in the world, producing up to 2% of the world’s copper, a critical mineral for the clean energy transition. In theory, Las Bambas can produce 320,000 metric tons of copper concentrate a year, but widespread protests over the social and environmental impacts of the mine and the transport of minerals have never allowed the mine to fulfill that potential.
