IDB Invest, the private-sector arm of the Inter-American Development Bank, will lead a financing package of up to $700 million to support a subsidiary of South Korea's Posco Holdings in expanding lithium production at its Sal de Oro project in Argentina, the lender announced on Friday.
According to an IDB Invest statement, the project is located in the northwest of the country, on the border between Salta and Catamarca provinces. Once fully operational, it is expected to produce approximately 48,000 metric tons of lithium per year and generate around 620 jobs.
The financing package comprises a loan of up to $250 million from IDB Invest, with an additional $450 million expected to be provided by other international financial institutions.
The funding is intended to enhance Argentina's capacity to process lithium into battery-grade materials. It will support the commissioning and phased expansion of two Posco Argentina facilities---one producing lithium hydroxide and the other lithium carbonate.
