/CNW/ -
Argentina Lithium & Energy Corp.
(TSXV: LIT) (FSE: OAY3) (OTC: PNXLF),
("Argentina Lithium" or the "Company")
reports positive lithium brine values at its Rincon West Project in
Salta Province
,
Argentina
, including a
153 m
interval ranging from 329 to 393 mg/l lithium
from the sixth diamond drill hole. The seventh
exploration hole is in final steps to completion, with two additional holes planned.
"The new drilling results extend the zone of concentrated lithium brines towards the west and southwest from earlier drill
intersections. The remarkable interval from the sixth hole, RW-DDH-006, is our best interval to date, and it is a step-out of
960 m
from the prior best intersection reported previously in the fourth hole. With RW-DDH-005, we drilled 1.7 km southwest
of the sixth hole, looking for the western limit of the brine zone. These large step-outs demonstrate concentrated lithium
brines extend broadly through the core of the property. The remaining three drill holes will be located to further delineate the
brine aquifer."
stated
Miles Rideout
, V.P. of Exploration.
The results of the brine analyses, type of sample collected, and the respective intervals from which brine was recovered are
shown in Table 1. Drill collar information is presented in Table 2.
The Rincon West Project, located west and north of Rio Tinto's adjacent Rincon Project, covers 3742.8 hectares of the salar
basin. Rincon West is currently permitted for up to 9 exploration drill holes.

presents a map of the Rincon West
property showing the positions of the seven initial exploration holes (see News Releases dated
July 13, 2022

and

). The map in Figure 1 displays the drill locations overlaid on the conductive zones
delineated with TEM geophysics (see

; Note: the easternmost property extension was acquired
after the completion of the TEM survey and therefore shows no geophysics results).

*Both drill holes were inclined vertically; the salar strata are believed to be flat lying resulting in reported intervals approximating true thickness.
Technical Details
Both holes were executed with diamond drilling (HQ-diameter), permitting the extraction of core samples of the salar basin
formations, and recovery of brine samples where possible. RW-DDH-005 was drilled
between September 26 and October 24,
2022
, stopping at 328.4 metres depth in volcanic units. Lining the hole with 2" diameter PVC filters and tubing was completed
on
October 26, 2022
.
RW-DDH-006 was drilled
between October 27 and November 26, 2022
, stopping at 329.8 metres depth in a metamorphosed
sedimentary unit. Final profiling and lining the hole with 2" diameter PVC filters and tubing were completed by
December 3,
2022
.
Drilling was carried out by Salta-based AGV Falcon Drilling SRL, under the supervision of Argentina Lithium's geologists.

LIT'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.
While drilling RW-DDH-005, every attempt at brine sampling with the single packer apparatus failed to recover significant
quantities of brine. Sampling was thus accomplished at intervals during drilling by employing a bailer unit to recover brines from
near the bottom of the drilled interval. A limitation of bailer sampling is that the interval is not sealed above, thus mixing with
solutions from upper portions of the hole is probable. The site geologists believe the lack of brine recovery during packer
sampling was likely related to the depth of the phreatic water table in the hole, identified approximately
72 m
below the collar.
Apparently the packer airlift system was unable to lift dense brines this height above the phreatic level.
In follow-up sampling, the drill crew was able to recover brines from selected intervals while employing a double packer
system.
Sampling with the single packer system was completed without significant difficulty at RW-DDH-006. In this case, the well
collar is situated at a lower elevation with a measured phreatic level of
37.6 m
.
Observations regarding RW-DDH-005
RW-DDH-005 is the westernmost hole completed to date, and the collar is located at the highest elevation yet tested on this
project. The hole tested gravels and volcanic clasts in a sandy matrix to
29 m
depth, where ignimbrite was encountered,
continuing to
41 m
depth. With a short transition, the drill entered medium-to-coarse gray sandstone from approximately
42 m
,
continuing to
54 m
, followed by a
1 m
layer of medium-to-fine black sandstone. Coarse gray sandstone was observed from
55
m
to
62 m
, followed by coarse brown sandy units with layers of sulphates, continuing to
77 m
depth. A brecciated sandstone
with sandy matrix then extends to
200 m
depth. This unit was intensively fractured between
176 m
and
197 m
depths.
Ignimbrite with varying degrees of fracturing was logged between
200 m
and
296.5 m
depths. The geologic log demonstrates
a complex sequence transitioning from ignimbrite to aphanitic volcanics between 296.5 to
306 m
depth. The hole was
terminated in volcanics at
328.4 m
depth.
Observations regarding RW-DDH-006
Breccias and conglomerates with sandy matrices were observed from near-surface to
32 m
depth. A sequence of sandy and
silty sedimentary units with sulphates followed, ending in a sequence of sandy clays, logged between 47 and
53 m
depth.
Brown coloured sandstones were observed from
53 m
, extending to
86 m
depth. From
86 m
to
95 m
, breccias with quartzite
fragments in a sandy matrix were logged. Ortho-quartzite then follows, continuing to
284 m
depth, with multiple zones of
relative competency interspaced by zones of intensive fracturing. A lithologic change was observed at
284 m
, with a silicified
sedimentary unit below. As the degree of fracturing reduced with depth, this unit was interpreted as a metamorphosed
sedimentary rock. The drill was stopped in this metamorphosed sedimentary unit at
329.8 m
depth.
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.
Analyses and QA/QC
Samples of brine were submitted for analysis to Alex Stewart International Argentina S.A. ("Alex Stewart"), the local
subsidiary of Alex Stewart International, an ISO 9001:2008 certified laboratory, with ISO 17025:2005 certification for the
analysis of lithium, potassium and other elements.
Alex Stewart
employed Inductively Coupled Plasma Optical Emission
Spectrometry ("ICP-OES") as the analytical technique for the primary constituents of interest, including boron, calcium,
potassium, lithium, and magnesium. Measurements in the field included pH, electrical conductivity, temperature and density.
The quality of sample analytical results was controlled and assessed with a protocol of blank, duplicate and reference
standard samples included within the sample sequence. For the holes RW-DDH-005 and 006 reported herein, the blank (2)
and duplicate (3) samples reported within the acceptable range. A single low-grade, medium-grade, and high-grade
reference standard sample was included within the submitted samples for each hole. The low-grade reference standard
analyses were above 3 standard deviations (SD) with less than 5% relative percent difference (RPD); the medium grade
reference standard returned one result above 3 SD and one at 2 SD above the best value with 1.47 and 1.00 RPD,
respectively; the high-grade reference standard returned one result less than 3 SD and one within 2 SD of the best value; with
low RPD (1.73 and 0.72, respectively).
