Lithium brine deposits are accumulations of saline groundwater that are enriched in dissolved lithium[1]. They are typically located in the high elevation areas of Bolivia, Argentina and Chile in South America with Chile being the largest producer. Brine deposits often contain large quantities of other useful elements such as sodium, potassium, magnesium and boron which offsets some of the cost of pumping and processing brine (source: IEA, Global Supply Chains of EV Batteries, p. 21).
