NOA LITHIUM ANNOUNCES MOBILIZATION OF 2026 EXPLORATION DRILLING PROGRAM AT RIO GRANDE PROJECT

NOA Lithium Brines Inc.'s drilling contractor has commenced mobilization to site for the company's coming 2026 exploration drilling campaign at its flagship Rio Grande project in Salta province, Argentina. These drilling activities are part of the plan to complete a preliminary feasibility study (PFS) for the project by year-end 2026. Drilling operations are expected to commence in the next month. As part of this program, NOA is pleased to report that site preparation activities and site preparation activities are already under way to support the start of drilling on schedule.

NOA's chief executive officer, Gabriel Rubacha, stated: "This mobilization marks the start of a key phase of fieldwork at Rio Grande as we work toward the PFS. Our 2026 program is focused on collecting the data needed to refine our hydrogeological and resource models and to advance the project through the next stage of technical studies."

In this initial stage, the company plans to drill exploratory wells near diamond drill holes DDH-RG23-001 (Sulfa X) and DDH-RG23-004 (El Camino II). The program is designed to evaluate the hydraulic parameters of deep brine-bearing aquifers and to support continuing refinement of the hydrogeological and resource models as the project progresses toward more advanced technical and economic studies.

The drill program has been reviewed and approved by Montgomery & Associates, which is currently preparing the water balance of the project and will participate in the preparation of the PFS of the project.
