Posted on April 16th, 2025 | Filed under Press Releases

BUENOS AIRES, AR / ACCESS Newswire / April 16, 2025 / NOA Lithium Brines Inc. (TSXV:NOAL)(Frankfurt:N7N) (“NOA” or the “Company“) is pleased to announce the appointment of Hatch Limited (“Hatch“) to lead the preparation of a Preliminary Economic Assessment (“PEA“) for the Company’s flagship Rio Grande Project (the “Project“) in Salta Province, Argentina.

The PEA will outline the economic parameters and development potential of the Project for an initial production capacity of approximately 20,000 metric tonnes per year of lithium carbonate equivalent (“LCE“). The plant design in the PEA is anticipated to incorporate scalability, with the potential to double capacity through the addition of a second 20,000 metrictonne module, for total capacity of approximately 40,000 metric tonnes per year of LCE.

The PEA is expected to be completed within four months, with results anticipated in Q3 2025. The findings will provide critical insights into the Project’s viability and will serve as a foundation for the next phase of development toward production.

NOA’s Chief Executive Officer Gabriel Rubacha states: “This marks a major milestone for NOA and the Rio Grande Project. Over the past two years, we’ve consistently delivered on our exploration and development goals, even amid challenging market conditions. We are excited to partner with Hatch, a firm with extensive experience in lithium project development across the region. Hatch’s technical expertise and global reputation give us confidence that the PEA will present a robust and credible valuation of our Rio Grande Project. This will be key to advancing the Project and unlocking further value for our shareholders.”
