| ABSTRACT: | LSC previously announced initial exploration results on the Salar de Pozuelos property in a press release dated April 10, 2017, including results for pumping step tests on pumping wells W1-35 and W2-90 located in the south-central part of the Salar de Pozuelos. Long-term pumping tests have now been completed on the two wells. A 30-day test was run on W1-35 and a 15-day test was run on W2-90. The planned 30-day tests for W2-90 was terminated at 15 days due to weather issues preventing fuel delivery for the generator. Pumping well W1-35 was drilled to a depth of 45 m and completed with a screen interval from 0 m to 35 m. Well W2-90 was drilled to a depth of 95 m with a screen interval from 35 m to 80 m. In addition, piezometric wells were drilled to depths of either 35 m or 90 m at distances of 5 m, 20 m and 50 m from the pumping wells to develop data on well performance. Short-term stress test results for W1-35 were reported in the April 10, 2017 press release. Results for the short-term stress tests for well W2-90 are reported here. Short-term pumping tests on well W2-90 (see LSC press release dated April 10, 2017 for location) were run to stress the well and develop data on the hydraulic properties of the 35 m – 80 m depth interval of the salar. The tests were run at pump rates of 5.29 m3 /hr to 13.14 m3 /hr over a 6-hour period. The maximum drawdown was 7.75 m at the maximum pumping rate. Brine samples were taken at periodic intervals throughout the test. The results showed consistent Li assays averaging 545 mg/L lithium and a constant Mg:Li ratio of 5:1. As anticipated, NEWS RELEASE LSCLITHIUM.COM LSC 2017 No. 03-06 | Page 4 drawdown was higher and recovery slower for the W2-90 compared to W1-35 due to the relatively low porosity and transmissivity of the deeper lying compact halite. Nevertheless, reasonable pumping rates were achieved. Overall, the long-term tests confirmed the consistent favourable chemistry of the lithium brine at Salar de Pozuelos and the productive capability of both the upper highly fractured halite zone and the lower, more compact halite zone. | |
