"Capital costs for Sal de Vida have been updated to reflect further optimisation in construction design and price adjustments for current materials and equipment pricing. The proposed location of Sal de Vida’s evaporation ponds have been re-located to the south east of the previous location, west of the plant camp and above the salar floodplain, to avoid the risk of water logging. The new location also provides better geotechnical characteristics for pond loading and for future expansion of the Project. The revised pond and plant location has resulted in an increase to the capital costs previously estimated because of design optimisation and an increase in bulk earthworks. The updated capital cost estimate also includes an increased allowance for owner’s costs, providing Sal de Vida with a greater working capital provision and a contingency of US$43 million."
