NOA Lithium Reports High-Grade Results from its Fifth Hole at Rio

Grande With Intercepts Averaging 471 mg/l Lithium over 530 Meters And

Provides Financial Update

April 12, 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

RG23-005, the fifth hole of the Phase 1 diamond drill program at its Rio Grande project (“Rio

Grande” or the “Project”). The hole, located at the Juana Azul claim within the salar, completed to

a depth of 602 meters (“ m”), intersected a high -grade lithium (“ Li”) brine aquifer of significant

thickness starting from a down-hole depth of only 1 m.

Highlights from the fifth drill hole include:

• Near-Surface: Lithium brine-saturated geological units were encountered starting at only 1

meter below surface, indicating the Project's vast potential.

• Extensive Brine -Bearing Units: Approximately 530 m of lithium brine -bearing units were

identified through 41 packer tests, affirming substantial lithium content within the salar.

• Average concentration of 464 mg/l Li in the upper 350 m, while the remainder of the hole

averaged a high-grade concentration of 474 mg/l Li; and

• Encountered highest-grade concentration of 607 mg/l Li at 203 m.

NOA’s Chief Executive Officer Gabriel Rubacha states: “The results of this 5 th hole reaffirm the

potential of our Rio Grande project. We are now focused on the next stages where we expect to

expand the resource drilling areas not explored yet and start our pumping holes campaign to support

the development of the project. We expect to start this second stage during Q2 this year”.

Hole R G23-005 was executed with diamond drilling (HQ -size), permitting the extraction of core

samples of the salar basin formations and collection of brine samples, where available. Drilling was

carried out by Salta-based Hidrotec S.A., under the supervision of NOA’s geologists.

Diamond drill hole RG23-005 was completed at a depth of 602 m. At a depth of 1 m, the formations

saturated with brine began . The lithology of the well is composed mainly by sand with sulfate

intercalations and a lower proportion of crystalline halite , with contents that are variable along the

depth of the well. Packer test sampling was carried out and almost the entire depth of the +600 m

NEWS RELEASE

well returned brine-saturated units (approximately 530 m of the 602 m drilled), except for one horizon

ranging 40 m in thickness.

Brine packer samples have been sent for laboratory analyses, including multi-element geochemical

analysis for lithium and other relevant elements, and results are expected in the coming weeks.

Selected drill core samples were sent to an accredited laboratory for physical property tests,

including drainable porosity.

Bridge Loan Financing

The Company also announces that it has entered into a short-term unsecured loan agreement (the

“Agreement”) with Mr. Gabriel Rubacha (the “Lender”), the Company’s Chief Executive Officer and

a Director. Under the Agreement and on or about April 8, 2024 (“Disbursement Date”), the Lender

will advance the Company a US D $1 million (the “ Loan Amount ”) term loan (the “ Bridge

Financing”) with repayment terms as disclosed below. The Bridge Financing is expected to be

repaid to the Lender in 60-90 days from the date hereof, as the Company is in advanced discussions

with strategic investors regarding longer term capital financing for the Company. The Company plans

to use the proceeds from the Bridge Financing to pay incurred capital expenditures and for general

corporate working capital.

The Bridge Financing will have a maturity date of December 31, 2024 (“Maturity Date”) and may be

repaid by the Company with interest, if any (“ Repayment Amount ”) in whole or in part with no

penalty at any time before the Maturity Date (the “ Repayment Date”). The Repayment Amount will

be determined by using the value of 142,000 common shares of Lithium Americas Corp. (“LAC”), as

traded on the New York Stock Exchange (“NYSE”) under the symbol “LAC”, multiplied by the closing

price of the LAC common shares on the NYSE on the Disbursement Date , which equals the Loan

Amount; and the exact Repayment Amount to be paid on the Repayment Date will be the aggregate

value of the 142,000 LAC common shares multiplied by the closing price of the LAC common shares

on the NYSE on the Repayment Date.

The Lender has also agreed to share in any such depreciation that may occur of the LAC common

shares between the Disbursement Date and the Repayment Date and for clarity only the same

number of LAC common shares as of the Disbursement Date will be required to be repaid by the

Company to the Lender on the Repayment Date.

Further and pursuant to the Agreement, b eginning on the date that is 150 days from the

Disbursement Date and until the Maturity Date, t he Repayment Amount may be converted into

common shares of the Company at a price per security that is the maximum allowable discount

permitted by the TSX Venture Exchange at the time the conversion is made and the accrued interest,

if any, becomes payable, and such convertible terms shall comply with the Policies of the TSX

Venture Exchange and be subject to approval by the TSX Venture Exchange.

NOA’s Executive Director, Hernan Zaballa, states regarding the Bridge Loan : “This financial

commitment provided by Mr. Rubacha continues to show the support and confidence of

management in the vast potential of the Rio Grande project.”

The Bridge Financing obtained from the Company's Chief Executive Officer and Director constitutes

a “related party transaction” under Multilateral Instrument 61 -101 - Protection of Minority Security

Holders in Special Transactions ("MI 61-101"). This transaction is exempt from the formal valuation

and minority shareholder approval requirements of MI 61 -101 pursuant to sections 5.5(a) and

5.7(1)(a) of MI 61-101 as neither the fair market value of the transaction, nor the consideration paid

to the lender of the Bridge Financing, who is a related party of the Company, would exceed 25% of

the Company's market capitalization. The Company will file a material change report with respect to

the Bridge Financing, however, the material change report will be filed less than 21 days prior to the

advancement of proceeds under the Bridge Financing.

The entering into of the Bridge Financing was considered and approved by the disinterested

Directors of the Company. The disinterested Directors voted unanimously to approve the Bridge

Financing and Mr. Rubacha declared a conflict and abstained from voting on the Bridge Financing.

The Bridge Financing remains subject to requisite approvals by the TSX Venture Exchange.

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 flus h 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 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, temp erature 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.
