Snapshot	Pampa de Pongo is a large iron ore mining project in Latin America. It is planned to produce iron concentrate and copper-gold concentrate. On April 2025, The National Service for Environmental Certification of Sustainable Investments (Senace) has approved the Modification of the Environmental Impact Assessment (EIA) for the Pampa de Pongo mining project, authorizing an investment of US$ 1.798 billion. Among the main approved modifications is the change of the mining method from open pit to underground mining. The project includes the construction of a Processing Plant, desalination plant, a filtration plant, a concentrate pipeline to the future port of San Juan de Marcona, and a tailings storage facility. This approval makes Pampa de Pongo one of the most important mining projects in the country, making a significant contribution to both the regional and national economies.

Summary:

(Translated from Spanish using ChatGPT)
Regarding the regional geology, the Pampa de Pongo mining deposit is regionally located along a metallogenic belt approximately 400 km long and 70 km wide, aligned with the Peruvian coast between Lima and Chala. It contains IOCG- and skarn-type deposits and lies within the morphostructural unit of the Ica–Nazca depression, structurally controlled by the Treinta Libras and Bella Unión faults.

In terms of local geology, the area is composed of Mesoproterozoic metamorphic rocks belonging to the Coastal Basement Complex; Paleozoic conglomeratic, pelitic, and calcareous rocks such as the San Juan and Marcona formations; Mesozoic volcano-sedimentary rocks such as the Río Grande, Jahuay, and Yauca formations; Neogene sandstones represented by the Pisco Formation; Quaternary marine–eolian deposits; and Cretaceous intrusive rocks. The replacement of the carbonate sequence by magnetite and the infilling of structures emplaced within volcano-sedimentary sequences are the most significant features of this type of mineralization.

Geochemically, the Pampa del Pongo (PDP) deposit consists of a magnetite (Fe3O4) mineralized body. The iron oxide mineralization replaces dolomitic rocks of the Marcona Formation, which are primarily composed of carbonate rocks.
