NOA Intercepts Over 500 Meters of Lithium Brine-Saturated Units in Third Hole at Rio Grande Project
NOA Intercepts Over 500 Meters of Lithium Brine-Saturated Units in
Third Hole at Rio Grande Project
September 6, 2023, Buenos Aires, Argentina – NOA Lithium Brines Inc. (TSX-V: NOAL, FSE:
N7N) (“NOA” or the “ Company”) is pleased to provide an update on the progress of the Phase 1
diamond drill program at its Rio Grande project (“Rio Grande” or the “Project”). Drilling on the third
hole, RG23-003, located at the Cristina claim on the surface salar was completed to a depth of 659
meters (“m”) and full laboratory results are expected in the coming weeks. Preliminary highlights of
the third hole include:
• Lithium brine-saturated geological units (“units”) starting at approximately 15 m below
surface.
• More than 500 meters of lithium brine-bearing units (48 total packer tests thus far).
• Believed to be the deepest reported occurrence of permeable brines at Rio Grande.
• Preliminary results confirm lithium content in the brine all along the depth of the well,
with lab geochemical analyses in progress.
NOA’s Chief Executive Officer Gabriel Rubacha states: “Results from our third hole are very
encouraging. As in our second hole which was also drilled on the surface salar, brines were
intercepted essentially starting at surface. In addition, o ver 80% of this +600 m hole intercepted
lithium brine-saturated units, representing an incredible thickness. With two rigs now operating, we
plan to start holes 4 and 5 in September and we remain on track to complete the 6-hole Phase 1 drill
program in Q4 2023 and finalize a maiden resource estimate for Rio Grande thereafter.”
Hole R G23-003 was executed with diamond drilling (HQ -size), permitting the extraction of core
samples of the salar basin formations and collection of brine samples where possible. Drilling was
carried out by Salta-based Hidrotec S.A., under the supervision of NOA’s geologists.
The lithological profile of the third hole is in-line with other drillholes at the Project. Almost the entire
depth of the +600 m hole returned brine-saturated units based on packer testing, except for a few
horizons of 10-30 m thickness. In general, halite and interstitial sands were the dominant lithologies,
with amounts of each varying along the depth.
Brine packer samples have been sent for laboratory analyses, including multi-element geochemical
analysis for lithium an d other relevant elements , and results are expected in the coming weeks.
NEWS RELEASE
Selected drill core samples will be sent to an accredited laboratory for physical property tests,
including drainable porosity.
The Phase 1 drill program is planned for six holes and is designed to deliver a maiden mineral
resource estimate for the Rio Grande project in early 2024. The location of RG23-003 is shown in
Figure 1 and its drill collar information is provided in Table 2 below.

About NOA Lithium Brines Inc.
NOA is a lithium exploration and development company formed to acquire and develop assets with
significant resource potential. All NOA’s projects are in the heart of the prolific Lithium Triangle, in
the mining-friendly province of Salta, Argentina, near a multitude of projects and operations owned
by industry leaders. NOA has rapidly consolidated one of the largest lithium brine claim portfolios in
this region that is not owned by a producing company, with key positions on three prospective salars
(Rio Grande, Arizaro, Salinas Grandes) and a total portfolio of approximately 100,000 hectares.

Sample analysis & QA/QC Program
The Company has a robust QA/QC and sample management program. Brine samples were collected
by a single / double packer system (in-hole inflatable) to isolate specific intervals down the drillhole.
The packer sampling method allows the collection of brine samples at specific depths while sealing
the hole at the top and bottom of the interval. The packer system was run several times to flush the
hole after drilling to clear / clean the hole prior to sampling and four samples for each interval were
collected (main sample, duplicate sample, check sampl e, reserve sample). The drillhole of the
current release was inclined vertically (90 degrees) and the salar strata are believed to be flat-lying
resulting in reported intervals approximating true thickness.
Samples of brine were submitted by courier for analysis to SGS Argentina S.A., the local subsidiary
of SGS International, an accredited laboratory for the analysis of lithium and other elements. SGS
employed Inductively Coupled Plasma Optical Emission Spectrometry as the analytical technique
for the pr imary constituents of interest, including: boron, calcium, potassium, lithium, and
magnesium. Measurements in the field included pH, conductivity, temperature and density. The
quality of sample analytical results was controlled and assessed with a protocol of blank, duplicate
and standard samples included within the sample sequence. Differences between original and
duplicate samples and results for standards and blanks are considered within the acceptable range
for lithium.
