Advantage Lithium Corp. provided this update on activities at the Cauchari JV property located in Jujuy Province, Argentina. Highlights: CAU07 30 day constant rate pumping test was carried out at a rate of 22 l/s throughout the test; the pumping rate was limited by the construction of the well. Results of brine analyses over the 30 days averaged 650 mg/l Li and 4,970 mg/l K with Mg/Li of 2.2:1. The 30 day test showed no drawdown in piezometers located above and at the top of the brine body. The dynamic level in the pumping well showed 40 m of drawdown over the test. An updated resource estimation is underway and will incorporate the significantly greater drilling depths of the Phase III program just completed. Preliminary design of production wellfields is underway for the Feasibility Study, using the results of the long-term CAU07 and CAU11 pumping tests. CAU07 Pumping Test: The 30 day constant rate pumping test was completed on test production well CAU07 in the NW Sector in mid-January. The pumping test was carried out at a constant rate of 22 l/s with a drawdown of 40 m. Assays received for the 30 days of the test averaged 650 mg/l Li and 4,970 mg/l K, with a Mg/Li ratio of 2.2:1. The CAU07 pumping rate is limited by well construction constraints and higher pumping rates are expected in future production wells based on the observed aquifer conditions. Brine samples were collected at regular intervals during the test and showed no significant variation over the test, with concentrations of between 642 and 659 mg/l lithium. Updated Resource Estimation and Preliminary Wellfield Design: An update to the project resource estimate is currently underway and incorporates all the information from the 26 exploration and test production wells that were drilled as part of the Phase II and Phase III exploration programs. During the Phase III program the resource area was extended to the south and in depth to a maximum of 617 m. These are some of the deepest holes drilled in the Cauchari-Olaroz basin to date. The Cauchari resource remains open at depth and to the south. By point of comparison the June 2018 resource estimate extended to only 300 m deep (with the exception of the deep sand intersections at that time).
