NOA Lithium Announces Launch of 2026 Activities at Rio Grande Project Leading to Preliminary Feasibility Assessment

BUENOS AIRES, ARGENTINA / ACCESS Newswire / January 21, 2026 / NOA Lithium Brines Inc. (TSXV:NOAL,OTC:NLIBF) ("NOA" or the "Company") is pleased to announce the Company has engaged Montgomery & Associates ("M&A") to start key activities for the hydrogeological model of the Rio Grande salar to support the Preliminary Feasibility Study ("PFS") for NOA's Rio Grande Project (the "RioGrandeProject" or "Project"). The PFS is planned to be completed before the end of 2026.

M&A has been working on NOA's Rio Grande Project since 2023 and they have extensive experience in Argentina and in the region. They have also worked on many of the projects in operation and under development in Argentina, including multiple producing and development stage lithium brine projects.

One of the initial preliminary tasks for the PFS is the preparation of a Basin Water Balance Report, scheduled to be completed before the end of Q1/2026. A Water Balance Report is a foundational engineering report for the Project that quantifies the total inflows, outflows, and storage changes of water within the Project's site.

NOA's Chief Executive Officer Gabriel Rubacha states: "This is another milestone in Rio Grande's journey to feasibility. Our goal this year remains to complete the PFS and this event marks the initiation of the activities necessary to achieve this".
