Argentina Lithium Confirms Lithium at Depth at Arizaro Salar and Extends Testing Program
14 Noviembre 2017 - 10:46AM
Argentina Lithium & Energy Corp. (TSX-V:LIT)
(FSE:OAY1) (WKN:A0RK7E) (OTC:PNXLF)
(“Argentina Lithium” or
the “Company”) is pleased to announce that the first two
drill holes at the Arizaro project have encountered lithium-bearing
brines below surface in the central area of the salar with values
as high as 257 mg/l lithium. A substantial brine aquifer has not
yet been reached but modest volumes of significantly anomalous
lithium-bearing brines were retrieved starting at depths of between
15 and 356 metres. The depth of drilling was limited by the
drill equipment used, therefore the Company plans to continue
drilling in these areas using suitable deeper-drilling equipment,
following more detailed geophysical and seismic surveys of the
Arizaro basin.
“Our model for this property was for a brine
aquifer at depth, so we were pleased to have anomalous results in
our first two holes,” said Nikolaos Cacos, President and C.E.O.
“These results support the theory of a source aquifer below where
we were able to reach, therefore we are continuing our exploration
to pinpoint the best location and depth to continue testing.”
Drill Program DetailsThree
holes have been drilled on the property, including two in the
central claim block (ARI-01, ARI-02) and one on the south claim
block. Due to time constraints on the program, two
drill rigs were employed. At hole ARI-01 the rig was capable
of deeper drilling, however it was unable to advance past 398
metres due to the rods getting trapped. Hole ARI-02 was
drilled using a rig capable of reaching 300 metres which was
originally considered sufficient based on the geophysics.
Later, due to the results from Hole ARI-01, the second hole was
considered prospective at lower depths, however the rig capable of
the deeper drilling was no longer available.
The central area holes both drilled through mainly massive
halite with short sections of intercalated clay layers, or layers
of sand. At approximately 300 metres depth Hole ARI-01 encountered
mainly sand with lessor sandstone layers to the end of the hole at
398 metres, with several anomalous results in these units.
Hole ARI-03 in the southern claim block drilled through a halite
cap to approximately 9 metres, then 23 metres of high porosity sand
that was followed by a mix of low porosity mixed sand units to 236
metres depth. The hole finished in the basement of red
conglomerates of moderate porosity. Drill hole
sections for the first two holes are shown in Figure 1:
https://argentinalithium.com/assets/news/Fig-1-DH-Sections-110917.pdf.
Results of sampling are compiled in Table 1
below, and hole location information is listed in Table 2
below. Samples of brine were obtained by either bailer or
packer testing, depending on the drill rig, as outlined
below. Volumes of brine were low and no substantial aquifer
was intersected. Hole ARI-01 ended in sands with highly
anomalous values, and the Company is optimistic that a higher grade
lithium-brine aquifer could still be present at greater
depths. ARI-02 ended in massive halite, however, it was
not drilled as deep as the first hole. These holes were
positioned based on low resistivity/high conductivity results from
the vertical electric sounding surveys, however this method
provides limited information at depths below approximately 300
metres. Therefore, the Company plans to execute a seismic and
Controlled-source Audio-frequency Magnetotellurics (CSAMT)
geophysical surveys to better map the depths of the basin and
conductive layers that may be related to lithium-bearing
brines.
Results for ARI-03 in the southern claim block
are incomplete at the time of writing, however based on preliminary
analyses the remaining samples from the bottom are expected to have
similar or lower levels of lithium and potassium to those from the
top of the hole.

Methodology and QA/QC
Samples in Hole ARI-01 were collected with a
double packer. This method allows the collection of samples at
specific depths while sealing the hole at the bottom and at the top
of the sample. The second drill rig used for holes ARI-02 and -03
was not equipped to sample with a double packer, therefore samples
were collected with a Bailer apparatus. Hole ARI-1 was drilled at
HQ3 size (outer diameter of 95.76 mm). Hole ARI-02 was drilled at
HQ3 from 0 to 105.3m and then completed at NTW size (75.88
mm). Hole ARI-03 was drilled from 0 to 140.15m at HQ3 then at
NTW.
All samples were collected in hard white plastic
1 litre bottles with samples numbers clearly identified. The
samples were sent to the Alex Stewart Argentina S.A laboratory in
Mendoza, Argentina (“Alex Stewart”), an ISO 9001:2008 certified
laboratory, with ISO 17025:2005 certification for the analysis of
lithium and potassium. 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, magnesium and sulphur.
Measurements in the field included pH, conductivity, temperature
and density. The laboratory took the same measurements and they
were consistent with the field data. A duplicate set of
samples with different numbering was sent to the Alex Stewart NOA
laboratory in Jujuy, and the results confirm the Mendoza lab
analyses.
About the Arizaro Lithium
ProjectThe Company has the option to earn a 100% interest
in the Arizaro Lithium Brine Project, including 20,500 hectares in
the central core of the Arizaro Salar, the largest in Argentina and
third largest in the “Lithium Triangle”. Very little historic
exploration work has been done on the Arizaro Salar, however the
central area is interpreted to have the geologic conditions to be
the most prospective for quality brine resources.
Furthermore, the Arizaro Salar benefits from a strategic location
for infrastructure, including: a railway that connects to the deep
water port of Antofagasta, nearby advanced mining projects that are
expected to bring significant development of access routes and
power, and the availability of water for development. For
additional information on the Project please see the Company
website www.argentinalithium.com.
Qualified PersonThe program was
undertaken under the supervision of David Terry, Ph.D., P.Geo., a
Director of the Company and a Qualified Person as defined in
National Instrument 43-101. The contents of this news release have
