Deposit Type

  • Hydrothermal


Summary:

The Las Truchas deposits consist of massive concentrations of magnetite of irregular morphology. The main Las Truchas deposits occur along about seven kilometers long and about two kilometers wide. The Las Truchas mineral deposits have been classified as hydrothermal deposits, which may have originated from injections of late stage-plutonic-activity through older sedimentary rocks. The mineralization of the Las Truchas iron deposits occurs in disseminated and irregular massive concentrations of magnetite within metamorphic rocks and skarns. The mineralization also occurs as fillings of faults, breccia zones, and fractures.


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Las Truchas mine is an integrated iron ore operation. It began operating in 1976 as a government enterprise (Sicartsa), and its mining activities consist of an open pit mine exploitation, crushing, dry cobbing preconcentrate and concentration plant.
