Underground in Mexico

Proaño and Francisco I. Madero are two of Mexico?s most successful mines. Owned by the Industrias Peñoles group, both use modern, mechanized equipment and rely on the same supplier to keep their fleets up and running, and their costs down. Adriana Potts reports on the arrangement and its contribution to the mine?s overall performance.

Mexican mines Proaño and Francisco I. Madero, in the state of Zacatecas, are no ordinary underground operations. The former is the world?s largest and most profitable underground silver mine and the latter is the country?s largest underground zinc mine. Their operations differ in every aspect ? except one. They both use state-of-the-art equipment and services from the same supplier, Atlas Copco.
