Maricunga is less than 5% the size of the lithium-rich Salar de Atacama in northern Chile, but high-grade deposits of the battery metal makes it attractive to miners.
North American Lithium (NAL), backed by top battery maker Contemporary Amperex Technology, halted operations last year at its Quebec mine and obtained creditor protection in May.
Private equity groups and other investors have grown emboldened by the lithium industry's malaise, forging plans to invest billions of dollars in mining projects to develop the electric vehicle battery metal.
The Chilean producer continues to suffer from dire conditions affecting the market of the metal used in batteries that power electric vehicles and high tech electronics.
