An accident at Antamina, Peru's largest copper and zinc mine, resulted in the death of a senior manager and injuries to another employee. The mine has been completely shut down for safety reasons.
The company confirmed that the accident occurred while employees were on duty at its Yanacancha mine in Huari, Ancash Province. In a statement, Antamina Minera Company said: “This is a difficult time for our Antamina Minera Company employees. We regret to inform you of the unfortunate death of our Senior Operations Manager, Mr. Edwin Colque Calisaya, due to an accident, and the injury of another colleague from the same area, the blasting supervisor, Yorhinio León Robles.” The company is investigating the cause of the accident and has contacted the families of the affected workers to offer support.
The Antamina mine is located in the Andes Mountains, 270 kilometers north of Lima, Peru. The deposit has an average altitude of 4.2 kilometers. The mine uses open-pit mining, relying on trucks and excavators. It has a 302-kilometer slurry pipeline that transports copper and zinc concentrates to ports for shipment to smelters and refineries worldwide. Antamina is jointly owned by BHP (33.75%), Glencore (33.75%), Teck Resources (22.5%), and Mitsubishi Corporation (10%). The mine currently has an operating capacity of 145,000 tons per day. Proven and indicated resources (including probable and possible reserves) total 863 million tons, with a copper grade of 0.87%, zinc grade of 0.60%, silver grade of 11 g/t, and molybdenum grade of 0.02%. In February 2024, Peruvian environmental regulators granted Antamina a permit for a US$2 billion (PEN 7.4 billion) expansion to extend the mine's life from 2028 to 2036.
