Orocobre Limited – NI 43-101 Technical Report Filing for Cauchari JV Property

BRISBANE, Australia, April 24, 2019 (GLOBE NEWSWIRE) -- Orocobre Limited (ASX: ORE, TSX: ORL) (“Orocobre” or “the Company”) wishes to advise that Advantage Lithium Corp. ("Advantage Lithium") (TSX V: AAL) (AVLIF) 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.

There are no material differences between the resource estimate in the Technical Report and the resource previously announced on 7 March 2019 (see ASX Release dated 7 March 2019). 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. Competent Person Mr. Murray Brooker reviewed advances for Orocobre during the drilling programs and during the resource estimation.

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 (see ASX Release dated 18 April 2019).

The NI 43-101 Technical Report can now be viewed on the Orocobre website: www.orocobre.com.
