NOA Lithium Closes $7 Million Non-Brokered Private Placement

NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR DISEMMINATION IN THE UNITED STATES

TORONTO, May 18, 2023 - NOA Lithium Brines Inc. (TSXV:NOAL) ("NOA" or the "Company") is pleased to announce it has completed a non-brokered private placement ("Private Placement") for the sale of 17,633,741 units (the "Units") at a price of $0.40 per Unit for gross proceeds of $7,053,496. All amounts expressed are in Canadian dollars.

Each Unit consists of one common share of the Company (a "Common Share") and one-half of one common share purchase warrant of the Company (each whole warrant, a "Warrant"). Each Warrant is exercisable into one Common Share at an exercise price of $0.60 for a period of 36 months from the date of issuance.

Taj Singh, President and CEO states, "In just a couple of months since going public we have made rapid progress. Our drill program at our flagship Rio Grande project resulted in the discovery of multiple brine horizons of significant thickness in the alluvial fans surrounding the salar in our first drill hole, with full assay results expected to be received shortly. Also at Rio Grande, we have strategically acquired claims to strengthen our position, both on the surface salar and in the alluvials. Most recently, we made an important acquisition at the Arizaro salar, materially increasing our land holdings here and acquiring a drill-permitted, high potential project on the surface salar. With the closing of this upsized financing, we are very well-positioned for long-term success."

The Company primarily plans to use the proceeds of the Private Placement for exploration of its properties, including accelerating the current drill program at its flagship Rio Grande project. The Private Placement is subject to a statutory 4-month and one day hold period from the date of issuance. The Private Placement remains subject to final approval of the TSX Venture Exchange and applicable securities regulatory authorities.

In connection with the Private Placement, an aggregate of $206,725 was paid in cash as finder's fees to Zaphiros S.A., Patricio Milic, Gustavo Kagel, Ignacio Marseillan, Ruben Jabib, and Stephen Avenue Securities Inc.
