NOA LITHIUM PROVIDES UPDATE ON 2026 EXPLORATION DRILLING PROGRAM AT RIO GRANDE PROJECT

NOA Lithium Brines Inc. has provided an update on its 2026 exploration drilling program at its flagship Rio Grande project in Salta province, Argentina.

The company reports that both drilling rigs are operating in accordance with the exploration program. Well RT-RG26-PW001, which commenced first, has reached a depth of 168 metres, and well RT-RG26-PW002 has reached a depth of 30 metres. The company expects to provide further updates on these wells as drilling advances and results are compiled.

NOA's chief executive officer, Gabriel Rubacha, stated: "We are pleased with the progress of our 2026 drilling campaign at Rio Grande. With both rigs operating as planned, we are advancing key field activities designed to further refine our hydrogeological understanding and support technical workstreams toward the project's preliminary feasibility study. We look forward to providing additional updates as the program continues."

The current drilling program is designed to support evaluation of deep brine-bearing aquifers and continuing refinement of the project's hydrogeological and resource models as NOA advances the project toward more advanced technical and economic studies.
