Pure Energy Minerals Limited (TSXV:PE) announced the results from the first two boreholes at its Terra Cotta project in Salar de Pocitos, Salta Province, Argentina. Anomalous concentrations of lithium were discovered in all brine samples from both diamond-drill core holes, with greater lithium concentrations observed closer to the center of the salar.
As quoted in the press release:
The drillers reached the target depth of 400 meters below surface on each of the two boreholes, TC-DD-01 and TC-DD-02. They employed a wire-line, triple-tube HQ system, averaging more than 80 percent core recovery in both holes. The first borehole was developed into an exploration well using 5 centimeter diameter PVC casing with screening over brine saturated intervals for possible additional sampling. Drill hole TC-DD-02 was grouted to the surface after completion with no casing installed.
The average lithium concentration for depth-specific samples collected from TC-DD-01 was 29 milligrams per liter (mg/L) lithium, ranging from 3 mg/L to 43 mg/L lithium. Sample depths ranged from 20 meters to 370 meters below ground surface. The depth-specific samples collected from TC-DD-02 averaged 65 mg/L lithium, including a range of lithium values from 29 mg/L to 93 mg/L lithium at depths from 15 meters to 310 meters below ground surface.
Walter Weinig, vice president for projects & permitting, commented:
The drilling at Terra Cotta showed dense brine and anomalous lithium concentrations throughout the sampled intervals. We are continuing to assess these results in conjunction with results from near-surface samples and surface geophysics as described in our press release of December 1, 2017 to evaluate our next moves for the TC Project. Several areas at Terra Cotta with anomalous near-surface lithium values and promising geophysical results have yet to be drilled.
