NOA Lithium Announces Strategic Arrangement with Hatch

BUENOS AIRES, AR / ACCESS Newswire / June 16, 2026 / NOA Lithium Brines Inc. (TSXV:NOAL,OTC:NLIBF)(Frankfurt:N7N) ("NOA" or the "Company") is pleased to announce that Hatch Ltd. ("Hatch") and the Company have agreed to make a strategic arrangement ("Arrangement") in connection with the Company's recently announced Pre-PFS Process Development Study for NOA's flagship Rio Grande project in Salta Province, Argentina (the "Study").

Under the Arrangement, Hatch, an arm's length party, has agreed to receive common shares of the Company for services completed by Hatch for the Study, which shall equal the fees and costs associated with the Study, being approximately USD $100,000. The Study is intended to compare the Project's baseline evaporation pond flowsheet against alternative process configurations incorporating direct lithium extraction ("DLE") testwork and concept-level process design.

NOA's Chief Executive Officer, Gabriel Rubacha states: "We are very pleased to welcome Hatch as an investor in NOA. Aligning a portion of the Study's cost with an investment by Hatch reinforces their confidence in the Rio Grande project and in our development pathway. This arrangement supports our goal of advancing key technical workstreams toward the PFS while maintaining disciplined capital allocation. The Study will help us evaluate process alternatives - including DLE-based flowsheets - and strengthen the technical foundation for a robust PFS."

Hatch's Managing Director - Minerals, Conrad Blake states: "Hatch is pleased to support NOA's continued advancement of the Rio Grande Project. We see significant value in disciplined, data-driven process development work at this stage, and we believe the Study can help clarify technology options and improve decision-making as NOA progresses toward a PFS. Our involvement reflects our confidence in the project and its team, and our commitment to supporting responsible development of critical minerals projects."

Terms of the Arrangement

Pursuant to the Arrangement, Hatch will be issued common shares of the Company for services rendered for the Study, with a value of approximately USD $100,000, and at a price per common share that will be determined by the volume weighted average ("VWAP") price of the common shares of NOA as listed on the TSX Venture Exchange based on a 5 day VWAP prior to the date of issuance. The common shares issued to Hatch will be subject to statutory hold periods and resale restrictions in accordance with applicable securities laws and stock exchange policies.

Completion of the Arrangement remains subject to customary conditions, including receipt of all required corporate and regulatory approvals, including approval of the TSX Venture Exchange.
