NOA LITHIUM ANNOUNCES LAUNCH OF 2026 ACTIVITIES AT RIO GRANDE PROJECT LEADING TO PRELIMINARY FEASIBILITY ASSESSMENT

NOA Lithium Brines Inc. 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 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 it has extensive experience in Argentina and in the region. It has 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, stated: "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."
