Advantage Lithium Corp. announced as operator of the Cauchari Joint Venture ("JV") has filed an independent NI 43-101 Technical Report ("Technical Report") on the Cauchari JV brine deposit located in Jujuy Province, Argentina. Orocobre owns 33.5% of Advantage Lithium's issued capital and 25% directly in the JV. The updated resource estimate was prepared with Mr. Frits Reidel of FloSolutions SpA of Santiago, Chile, being the independent Qualified Person for NI 43-101 purposes who reviewed the technical content of the report. Based on an intensive and successful drilling campaign in 2018, the updated estimate has increased the resource to a volume of 1.9km3 of brine at an average concentration of 476 mg/l lithium equivalent to 4.8 million tonnes ("Mt") of Lithium Carbonate Equivalent ("LCE") in the Measured and Indicated ("M&I") categories. The Inferred resource is now estimated at 0.6km3 of brine at an average grade of 473 mg/l lithium equivalent for 1.5 Mt of LCE. The M&I resource will now form the basis for a Pre-Feasibility Study currently underway.
