Peru's miners increased production of copper, zinc, iron ore and molybdenum through the first three quarters, while that of silver, lead and tin declined, according to the government.
Freeport-McMoRan's Cerro Verde mine produced 380,455t copper through the first three quarters, followed by China Minmetals' Las Bambas (331,814t), Antamina (331,169t), Southern Copper (223,556t), Glencore's Antapaccay (143,803t), Chinalco's Toromocho (137,232t) and Hudbay Minerals' Constancia (87,945t), the ministry said.
Zinc production rose 11.7% to 1.08Mt on gains at Antamina, while iron ore increased by 17% to 6.78Mt at Peru's only producer Shougang Hierro Perú. Molybdenum was up 9.5% to 20,893t and bismuth jumped 59.4% to 248t.
Silver output slid 1.1% to 3.25Mkg, lead was down 3.6% to 227,679t and tin at Peru's only producer Minsur dropped 2.2% to 13,655t, according to the ministry. Byproducts such as silver and lead fell as polymetallic miners focused on their zinc deposits amidst surging prices, according to the national mining society (SNMPE).
Manganese production declined 3.8% to 849t, while that of cadmium at Votorantim Metais' Cajamarquilla refinery dropped 4.8% to 582t and arsenic fell 2.1% to 15,870t.
Minerals account for about 60% of the country's total exports. Peru, the world's second largest copper and silver producer, third ranked in zinc and tin and No. 5 in gold, aims to boost annual copper output to 3Mt/y by 2021.
