Argentina Lithium & Energy Corp. reported the completion of the ninth exploration hole at its Rincon West Project in Salta Province, Argentina, returning a 258 m interval ranging from 287 to 402 mg/l lithium. Two portions of this interval were not sampled, one length of 42 m and a second length of 33 m. The Rincon West Project is located west and north of Rio Tinto's adjacent Rincon Project, and covers 3742.8 hectares of the salar basin.

Technical Details: RW-DDH-009 was executed with diamond drilling (HQ-diameter), permitting the extraction of core samples of the salar basin formations and recovery of brine samples where possible. Drilling was executed between February 28 and March 23, 2023 stopping at 341.0 metres depth in altered volcanics. Geophysical profiling and lining the hole with 2" diameter PVC filters and tubing were completed on March 28, 2023.

Drilling was carried out by Salta-based AGV Falcon Drilling SRL, under the supervision of Argentina Lithium's geologists. Argentina Lithium's preferred method for brine sampling deploys a 'single packer' sampling unit during drilling. The packer sampling method allows the recovery of brine samples at specific depths while sealing the hole at the top and bottom of the interval.

For single packer sampling, an inflatable seal closes the top of the interval; the lower limit of drilling represents the bottom of the interval. In certain instances, double packer sampling is conducted following the completion of drilling. In this case, inflatable seals are employed to close both the top and bottom of the sample interval.

The maximum span of double packer sampling is limited to less than 4 m by the height of the drill mast and other equipment limitations. Observations regarding RW-DDH-009: RW-DDH-009 extends drilling northwards from previous holes. From near surface to 39 m depth, gravel and sand units were crossed, with rock clasts observed in the sandy sediments below 24 m depth.

Sandy beds, and also minor gravel laminations were observed from 39 m to 59 m. Below this followed 2 m of silt and then 2 m of black sands. Medium-to-fine gravels were tested between 63 m and 110 m depths, followed by ignimbrites to 155 m. From 155 m to 238 m, a medium to coarse breccia was tested containing ignimbrite clasts. This unit exhibited fracturing and alteration at several levels.

Ignimbrite, certain levels with fracturing, were tested between 238 m and 266 m depths, followed by a 2 m thick altered fault zone. An auto breccia of ignimbrite containing igneous clasts was logged to 316 m. Copper oxide streaks were observed within this unit at 289.6 m. Volcanic units with increased fracturing, and also fracture filled with a green mineral, were recovered from 316 m to the bottom of the hole at 341 m. All core samples recovered in drilling were retained for geologic logging. An extensive selection of samples has been sent for brine recovery testing at an independent laboratory.

This analysis remains pending.
