NOA Lithium Acquires New Claims At Its Flagship Rio Grande Project

March 29, 2023, Toronto, Ontario – NOA Lithium Brines Inc. (TSX-V: NOAL) (“NOA” or the

“Company”) is pleased to announce that it has recently acquired two mining claims covering 896

hectares (“ha”) at the Rio Grande salar, located in Salta province, Argentina.

One of the claims, the Purita claim (“Purita”), is 60 ha and lies directly within surface s alar,

immediately adjacent to claim blocks controlled by NOA and surrounded by claims owned by

Pluspetrol Resources Corporation , which host an existing lithium resource (see “About Rio

Grande Project” below). NOA acquired Purita by winning the public tender to purchase the claim

for a cost of US$330,000 in instalments over one year from Recursos Energeticos Y Mineros De

Salta S.A. (“REMSA”, the state-owned mining company of Salta ). REMSA retains a 2% NSR

royalty on this claim which is purchasable by the Company for a cost to be negotiated prior to

purchase.

The other newly acquired claim, the West Road claim (“West Road”), 836 ha, is located in the Rio

Grande basin at the alluvial fan / northern salar interface and was acquired through lottery ($5,000

to enter) from the Salta Province Mining Court and carries no royalties . This claim also lies

immediately adjacent to large claim blocks under the Company’s control and where NOA believes

there is a good potential for lithium-bearing brines based on previous geophysical studies carried

out by others as well as NOA. West Road provides continuity with the other claims already

controlled by NOA, and where the Company is currently executing its drilling campaign.

Both new claims will form part of the Company’s flagship Rio Grande project (the “Project”), which

inclusive of these acquisitions, brings the Company’s total controlling position to 37,027 ha at the

Rio Grande salar. The Company also holds a 100% interest in approximately 44,000 ha of claims

located at the Arizaro salar, and 9,200 ha of claims located at the Salinas Grandes salar.

Taj Singh, President & CEO of NOA, stated, “These recent claim acquisitions further strengthen

NOA’s position on an exciting and underexplored lithium salar in the Lithium Triangle. NOA is one

of the largest claimholders at Rio Grande and these acquisitions not only increase our resource

potential at the Project but also add land holdings in the immediate vicinity of our core claim block

positions, both on the salar and in the basin. We look forward to continuing to strategically expand

our land positions at our current projects and elsewhere in the region.”

A map showing the Rio Grande project land holdings, including the acquired claims, can be found

NEWS RELEASE

About the Rio Grande Project

NOA controls a 100% interest in approximately 37,000 ha of claims located at the Rio Grande

salar in Salta Prov ince, Argentina. The Project is approximately 70 kilometers (“km ”) from the

Company’s Arizaro project and 250 km from its Salinas Grandes project. The Rio Grande salar is

known to host lithium -bearing brines with production potential. Pluspetrol owns the most

advanced project on the Rio Grande salar and acquired these claims through its acquisition of

LSC Lithium Corporation (“LSC”) in 2019. At the time of this acquisition, LSC had an inferred

resource of 2.2 million tonnes of lithium carbonate equivalent (“LCE”) at an average grade of 374

milligrams per liter (“mg/l ”) lithium, as disclosed in the most current technical report, with an

effective date of March 28, 2018, that can be found on LSC’s SEDAR profile.

Location & Infrastructure

The Rio Gr ande salar is located at approximately 3,600 m etres (“m”) above sea level, and the

geological environment at the salar is similar to other salars in the Puna region where lithium and

potash are commonly present. The Project is situated close to Provincial Route 27, and 185 km

south of Provincial Route 51, the international road that connects to Chile’s coastal ports, and is

50 km away from the Caipe international railway station. The InterAndes power corridor runs

within a few km of the Rio Grande salar.

Previous Exploration

Significant exploration has been carried out by various operators at Rio Grande, including

extensive drilling. Typical lithium values intercepted are in the 350 -450 mg/l range. NOA carried

out geophysical testing in 2022 on its Rio Grande claims which indicated significant brine potential

in the alluvial fans of the salar, and for the claims on the surface salar, brine potential was

indicated down to the salar basement of ~500 m, significantly deeper than what has been

historically dri lled on this salar. Certain applicable exploration data and geophysical results

suggest that lithium concentrations may increase with increased depths in and around this salar.

Current Exploration Program

The Company is currently executing a core drill program at Rio Grande. Its first drill hole is located

in the north of the salar, on the Sulfa X claim (Figure 1). The hole is well-advanced, and results

are expected early Q2 2023. The next hole planned will be drilled within the surface salar.

About NOA Lithium Brines Inc.

NOA is a lithium exploration and development company formed to acquire 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 some

of the largest players in the lithium industry. 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 pros pective salars (Rio Grande, Arizaro, Salinas Grandes) and totaling over

100,000 hectares.
