Mexico’s enormous mineral potential does not exclude copper. The country is home to the world’s second-largest copper mine by reserves: Buena Vista del Cobre, owned by Grupo México. In fact, of the 696,580 tons of copper Mexico produced in 2018, Grupo México’s mines produced 552,864. Sonora was the top producer, followed by Zacatecas and Baja California Sur. Mexico was the ninth-biggest producer of copper in the world. Most of its exports of ore and concentrates went to China, totaling 1,258 tons.
