| ABSTRACT: | Orocobre Limited (ASX: ORE, TSX: ORL ) (“Orocobre” or “the Company”) is pleased to provide an update on the brine sampling of diamond core hole CAU17 in the NW Sector of the Cauchari JV properties located in Jujuy Province, Argentina. The exploration program is being managed by JV partner Advantage Lithium Corp. ("Advantage Lithium") (TSX Venture: AAL) (OTCQX: AVLIF) who hold 75% of Cauchari. Orocobre owns 29% of Advantage Lithium’s issued capital. CAU17 was drilled in the NW Sector, 2.6 km west of CAU18 for which results were released on the 10th of April, 2018. CAU17 was pre-collared with surface casing cemented to a depth of 140 m through the shallow fresh / brackish groundwater of the Archibarca alluvial (gravel) fan that overlies the deeper brine in this area. Brine is estimated to extend from above 140 m depth to the base of the hole at 237.5 m depth. CAU17 intersected an extensive sequence of gravel and sand dominated units in drill core from 146 m to 210 m depth, with gravel and sand units intersected from surface in the pre-collar. A clay / silt dominated unit was encountered near the bottom of the hole between 210 and 237 m depth. Brine 2 sampling in CAU17 was conducted with a bailer device and three samples were obtained within the gravel unit at 178, 185 and 203 m depth. The lithium concentrations ranged between 549 and 606 mg/l and averaged 571 mg/l lithium and 4,488 mg/l potassium. The Mg/Li ratio of these samples was 2.3:1, identical to the producing Olaroz project to the north. | |
