NOA Lithium Provides Update on 2026 Exploration Drilling Program At Rio Grande Project

BUENOS AIRES, AR / ACCESS Newswire / July 16, 2026 / NOA Lithium Brines Inc. (TSXV:NOAL)(Frankfurt:N7N) ("NOA" or the "Company") is pleased to provide an update on its 2026 exploration drilling program at its flagship Rio Grande Project (the "Project") in Salta Province, Argentina.

The Company reports that both drilling rigs continue to operate in accordance with drilling plan. Well RT-RG26-PW001 has reached 254 meters, and Well RT-RG26-PW002 has reached its planned exploratory borehole at a maximum depth of 504 metres. Borehole Magnetic Resonance (BMR) logging has been completed at Well RT-RG26-PW002 and the production well has been designed. The Company expects to provide further updates on these wells as drilling advances and results are compiled.

NOA's Chief Executive Officer, Gabriel Rubacha states: "We are pleased with the progress of our 2026 drilling program at Rio Grande, with both rigs continuing to operate in accordance with our plan. Reaching the planned depth at RT-RG26-PW002 and completing BMR logging are important steps toward finalizing the first production well and advancing the testing phase. We look forward to providing further updates as drilling and testing activities progress."

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