Production Start...
Mine Life14 years (as of Jan 1, 2022)
ArcelorMittal Mexico launched a project to increase pellet feed production to 2.3 million tonnes per annum and improve concentrate grade in Las Truchas. This project will enable concentrate production to the blast furnace route and DRI route. All equipment purchase orders were placed and civil construction of the main buildings is about to commence. Due to delay in equipment delivery and construction works, production is expected to start in the second half of 2024.

Deposit Type

  • Skarn
  • 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 is a production stage mine. Mining activities consist of an open pit mine exploitation, crushing, dry cobbing preconcentrate and concentration plant.
