Project Details


The Cauchari-Olaroz lithium/potash brine project is an 82,500ha property comprising a significant portion of two adjacent salt lakes. The Cauchari and Olaroz salars are classified as "Silver Peak, Nevada" type terrigenous salars, characterized by restricted basins within deep structural depressions in-filled with sediments differentiated as inter-bedded units of clays, salt (halite), sands and gravels. On the surface, the salars are presently covered by carbonate, borax, sulphate, clay and sodium chloride facies. Cauchari and Olaroz have relatively high sulphate contents and therefore both salars can be further classified as "sulphate type brine deposits".
