SnapshotArcelorMittal is advancing a revamping project at the Las Truchas mine to increase pellet feed capacity by 1 million tonnes per year to 2.3 Mtpa, with DRI concentrate grade capability. The project is intended to support concentrate production for both BF and DRI routes and is expected to be completed in 1H 2027.

The concentrated ore was pumped from the mine site through a 26-kilometer slurry pipeline to the steel plant facility in Lázaro Cárdenas.

In 2024, Las Truchas was affected by an illegal blockade from May to July, with full operational recovery reached in Q1 2025.

In 2025, ArcelorMittal reported ongoing land disputes affecting surface rights on parts of the Las Truchas property; the impacted area represents 37% of total estimated mineral reserves, with affected reserves downgraded from Proven to Probable where applicable.

  • Hydrothermal
  • Metamorphic hosted

Summary:

The Las Truchas deposits consist of massive concentrations of magnetite of irregular morphology. The main Las Truchas deposits occur along a geological trend that is 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 late-stage plutonic activity injecting 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.
