NOA Lithium Reports High-Grade Results from its Fourth Hole at Rio Grande With Intercepts Averaging 619 mg/l Lithium over 400 Meters
NOA Lithium Reports High-Grade Results from its Fourth Hole at Rio
Grande With Intercepts Averaging 619 mg/l Lithium over 400 Meters
January 17, 2024, Buenos Aires, Argentina – NOA Lithium Brines Inc. (TSX-V: NOAL, FSE:
N7N) (“NOA” or the “Company”) is pleased to report positive lithium results from brine samples from
RG23-004, the fourth hole of the Phase 1 diamond drill program at its Rio Grande project (“Rio
Grande” or the “Project”). The hole, located at the El Camino claim on the northeast edge of the
salar, completed to a depth of 551 meters (“m”), intersected a high-grade lithium (“Li”) brine aquifer
of significant thickness starting from a down-hole depth of only 2.5 meters (“m”).
Highlights from the fourth drill hole include:
• 400 meters (2.5 m – 511 m) grading an average of 619 milligrams per litre (“mg/l”)
lithium;
• Average concentration of 360 mg/l Li in the upper 100 m, while the remainder of the hole
averaged a high-grade concentration of 675 mg/l Li; and
• Encountered highest-grade concentration of 794 mg/l Li at 333 m.
NOA’s Chief Executive Officer Gabriel Rubacha states: “Our drilling at Rio Grande continues to yield
very positive results, confirming the high-grade potential of the Project. In particular, this fourth hole
demonstrates the significant potential in the northern and northeastern areas of the salar , where
NOA’s claims cover a large, prospective area of the Rio Grande project. We are currently completing
our fifth hole, which is expected to be finalized in the coming weeks, and are eagerly looking forward
to announcing our maiden resource estimate , which remains on track to be completed later this
quarter.”
Diamond drill hole RG23 -004 was completed at a depth of 551 m. From a depth of 2.5 m, the
formations saturated with brine began. The lithology of the well is composed mainly of gravel and
sand with intercalations of halite and sulfates, whose thickness varied along the depth. Packer test
sampling was carried out, revealing brine-saturated units throughout nearly the entire depth of the
+500 m ( covering approximately 400 m of the 551 m drilled), with the exception of four horizons
ranging from 14 m to 29 m in thickness.
Hole RG23-005, the fifth hole of the Phase 1 diamond drill program at the Rio Grande project, is well
advanced and is anticipated to be completed in the coming weeks. The location of RG23-004 and
NEWS RELEASE
RG23-005 are shown in Figure 1. The ongoing Phase 1 drilling campaign will constitute the basis for
the maiden resource at the Rio Grande Project and is scheduled for release in Q1/2024.
Hole R G23-004 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.
Results for Hole RG23-004
The results of the brine analyses and the respective intervals are shown in Table 1 below and drill
collar information is presented in Table 2 below. Hole RG23 -004, drilled at the El Camino claim
(shown in Figure 1 below) reached a depth of 551 m.

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 sampl e, duplicate sample, check sample, 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 Alex Stewart NOA, subsidiary of Alex
Stewart International Argentina, member of the Alex Stewart International group, an accredited
laboratory for the analysis of lithium and other elements. Alex Stewart employed Inductively Coupled
Plasma Optical Emission Spectrometry as the analytical technique for the primary 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.
