This project aims to resume the extraction of caliche, a key mineral in the production of potassium nitrate, and to extend operations until 2030. The site, which has been inactive since 2019 due to market conditions and operational requirements, represents a key component in SQM’s production strategy for the coming years.

Modificación y Optimización de Faena Minera Mantoverde en comuna de Chañaral y transporte de concentrados a puertos de zona de Mejillones
The “Modification and Optimization of the Mantoverde Mining Operation, in the commune of Chañaral, and transport of concentrates to ports in the Mejillones area” Project aims to optimize the operations and processes of sulfide ore at the Mantoverde mining site to increase copper processing capacity.
The "Spence Operational Adjustment" project involves adapting Spence’s current leaching operation, thereby extending the lifespan of this process until the year 2039.
Primary Mineral:
Copper
Projected production:
Considerar el tratamiento de mineral 95.000 - 105.000 ton??
This Project will optimize the current operations of the Laguna Seca Concentrator Plant Complex, as a reduction in copper production is expected due to declining ore grades and increased mineral hardness.
In addition, to implement a new electrical transmission line of approximately 300 meters within the PCLS area, necessary to supply energy in light of the planned adjustments.

Projected production:
Verificar producción estimada, entendiendo que es una expansión de una concentradora, verificar producción de laguna seca
Exploitation of copper and magnetite mineral reserves from open pits located in the Sierra de Santo Domingo in the municipality of Diego de Almagro. The extracted mineral will be processed using conventional flotation to obtain copper concentrate. The flotation tailings will then undergo a magnetic separation process to obtain magnetite concentrate.
Optimization and operational continuity, extending the Life of Mine by 23 years, according to increased reserves and resources. Entails an average ore processing rate of 90,000 tpd
The exploitation of brine from the northeastern sector of the Maricunga Salt Flat using solar evaporation and subsequent precipitation in processing plants.
Ensure operational continuity until 2037 for the production of copper cathodes, through the extraction of our own ore from the Papomono underground mine and external ore from our purchasing power.
Tailings leaching project that seeks to process secondary and mixed minerals through sodium chloride enhanced leaching to optimize copper recovery and with a projected lifespan of 30 years
A project to modernize the current smelter to meet high environmental and production standards, including an electrolytic refinery and a precious metals plant.
The project is a modification of an existing project. Its objective is to continue operations at the Michilla mining site through a new mining method (underground) and the reactivation of certain sectors, without exceeding the mineral processing capacity already authorized under RCA No. 106/2018.
Primary Mineral:
Copper
Projected production:
COCHILCO: 23.000 ton/year
SEA: El Proyecto generará cátodos de cobre, la producción durante toda la vida

Its objective is to build and operate a new gypsum board manufacturing plant for sale in the construction market, with a particular focus on social housing construction, and to expand gypsum mining at the Rubí quarry, which will supply raw materials to the plant.
Its overall objective is the underground exploitation of the Ciclón and Exploradora mines, with the aim of extracting the polymetallic minerals present in both veins (mainly copper, zinc, silver, lead, and gold), with an estimated useful life of 16 years of operation. The underground mines will be exploited using the “Bench and Fill” method, with both underground mines feeding the Processing Plant.
