Peñoles

Metals

The metallurgical business produces high-purity refined metals from complex concentrates and other materials sourced from own and third-party mines. In this way, we generate value for end consumers across a wide variety of industries, both nationally and internationally.

Peñoles’ Met-Mex metallurgical operation is composed of two plants and a metallurgical complex, known as Aleazin, Bermejillo and Met-Mex, respectively. Met-Mex produces refined gold, silver, lead and zinc, and is one of the largest metallurgical operations in the world.
