Advantage Lithium Corp. announced that it will immediately undertake a Pre-Feasibility Study ('PFS') on its Cauchari JV following the doubling of its mineral resource and successful conversion to Measured and Indicated categories announced on March 7th 2019. Given such a significant resource increase, the PFS will now examine various alternatives to unlock additional value compared to the results from the 2018 Preliminary Economic Evaluation ('PEA'). A key outcome of the PFS will be delivery of a mineral reserve backed by an economic analysis demonstrating the viability of the project. The company expects to complete the PFS which is fully funded in third quarter of 2019. Final proposals from independent qualified consultants are currently being reviewed with kick-off study date expected shortly.
