Lithium Exploration Concessions, Chile

Strike has, through its associates in Chile, lodged applications to secure a number of exploration concessions in Northern Chile totalling approximately 4,700 hectares in area, in a region that hosts some of the largest lithium deposits and operations in the world. The project area is reported to contain ‘caliche’ style mineralisation which is formed predominantly from hardened deposits of sedimentary alkali metal salts (halides, nitrates and sulfates). Caliches consist mainly of calcium carbonates (CaCO3) but in some parts of northern Chile, Argentina and Bolivia, these minerals are relatively rich in lithium and other elements. Initial soil sampling reported by the previous holders of the concessions has confirmed the presence of lithium mineralisation within the tenements, with assay results returning elevated grades of lithium above 1,000 ppm.
