Advantage Lithium Corp. provided general update on activities at the Cauchari JV property located in Jujuy Province, Argentina. Highlights: The Phase III infill drilling and resource conversion program is close to completion in the NW Sector and continues in the deep sand unit in the SE Sector. The program is currently on track to upgrade the current Inferred Resource to Measured and Indicated Resources by early 2019. Drilling of holes CAU22, CAU25, CAU27 and CAU19 recently completed in the SE Sector; Drilling of holes CAU28 and CAU29 completed to extend the NW Sector resource area further south, increasing it by ~20%. Drilling identified the presence of an extensive (>300 m thick) sequence of sand and gravel in the southern continuation of the NW Sector. Constant-rate pumping test underway in CAU11 to simulate long-term production; CAU07 pumping test to begin within 2 weeks. NW Sector Drilling Update: Drilling is close to completion in the NW Sector with holes CAU28 and CAU29 completed since the last update on activities when CAU24 was completed. CAU28 and CAU29 extend the June 2018 resource area some 5 km further to the south and increase the area for the update of the NW Sector resource by approximately 20%. CAU28 and CAU29 are located 2.6 km and 5.1 km, respectively, south of CAU24. It should be noted that brine mineralisation is still open to the south in Advantage properties. These drill holes in the NW Sector have intersected an extensive sequence (over 300 m) of sand and gravel, which appears to have high porosity and permeability, making it attractive for future brine extraction. CAU23 is located in the NW Sector between holes CAU15 and CAU24. SE Sector Drilling Update: CAU25 and CAU27 have been completed along the eastern edge of the SE Sector. These holes were completed at depths of 427 and 473 m, respectively and intersected a sequence with some sandy material interbedded with halite and clay units. CAU19 has been completed in the southwest of the SE Sector to a depth of 519.5 m. This hole intersected the deep sand unit from 434 m to 519.5 m (a thickness of >86 m), with sandy units continuing at the end of the hole. CAU19 is close to the southern boundary of the property and confirms the extension of the deep sand into this area. Pumping Tests: The constant rate pumping test is currently underway on test production well CAU11 in the SE Sector, following completion of a variable rate test to confirm the pumping rate for the constant rate test. The constant rate test has been underway for 19 days and will continue until at least November 25. Brine concentrations are monitored throughout the test, in addition to water levels in the pumping well and a network of surrounding observation wells. The final preparations are currently underway for the CAU07 pumping test in the NW Sector. The tests will provide additional information on aquifer characteristics as an input to the three-dimensional groundwater model that is being developed to estimate lithium reserves and to develop a production schedule for the project.
