Antamina Copper-Zinc Mine

Antamina (Ancash Region, Peru; altitude ~4,300m; BHP 33.75%, Glencore 33.75%, Teck Resources 22.5%, Mitsubishi Corporation 10%) is one of the world's largest polymetallic mines — producing both copper and zinc concentrates, plus significant molybdenum and silver. Annual production approximately 370,000-420,000 tonnes copper equivalent. Antamina is a skarn deposit (copper-zinc mineralization where copper-rich and zinc-rich ore zones alternate, requiring separate concentrate streams). The mine is connected to the coast by a 302km dedicated slurry pipeline — concentrate is pumped as a slurry to the port of Punta Lobitos (near Huarmey) for shipment. The pipeline is one of the longest concentrate pipelines in the world. Antamina is considered one of the highest-quality large copper assets globally due to its polymetallic credits (zinc and molybdenum revenues offset copper cash costs), resulting in very low net copper production costs.
