The Company has 20 exploration concessions in northern Chile which are valid till 10 May 2019 and cover part of the Salar de Miraje, an enclosed rift basin in the Atacama Desert. On present evidence, Salar de Miraje is geologically analogous to the Salar de Atacama rift basin 150km to the south east, that produces a third of the world’s lithium from brines within the sediments deposited in the basin.


Resource:


Geology/Geophysics:

The Company’s concessions are within salars in the central belt of northern Chile, all at an altitude of around 1000m and the salars typically have a surface salt crust. The salars are formed in hydraulically closed basins formed by uplift and rifting of the western margin of South America. The search for lithium brines is focused on the salars because it is anticipated that evaporation over time has concentrated lithium in ground waters trapped in these salars. The fact that this evaporation has taken place is confirmed by the presence of modern salt crust and the historic nitrate and borax mining operations in the salars, both deposit types being the result of evaporation. The salars offer ideal situations for the construction of evaporation ponds on their flat surfaces, with the intention of pumping lithium bearing ground waters to the surface and concentrating the lithium by further evaporation in the ponds, prior to shipment to processing facilities.


Forward Program:

As preliminary surface sampling results have been very encouraging the Company intends to follow up with a drilling campaign to sample brines within selected areas.
