Project scope and objective
The Project entails developing, constructing, and operating the greenfield Salar del Rincon battery-grade lithium project located on the Salar del Rincon in Salta Province, Argentina (the “Project” or “Rincon”). Rincon is expected to produce ~up to 53 thousand tonnes per year (ktpa) of battery-grade Lithium Carbonate Equivalent (LCE) over its 40-year mine.
The Project will include wellfields and a brine distribution system, a spent brine disposal facility, a processing complex, filtered waste storage facilities, power transmission lines (two 23 km, 33 kV lines), and ancillary infrastructure.
The Project cost is estimated at ~US$2.5 billion. It will be financed using a combination of debt and equity. The proposed IDB Invest investment comprises an A Loan of up to US$100 million, and the remaining debt requirements will be financed through parallel loans
