NOA Lithium’s Fresh Water Discovery at Rio Grande Project Signals Major Advancement

The discovery of a fresh water source by NOA Lithium Brines Inc. at its 100%-owned Rio Grande Project in Argentina’s Lithium Triangle represents a critical milestone in the project’s development. This finding is particularly significant in the arid regions of the Lithium Triangle, where water is as scarce as it is essential for lithium brine projects. The strategic location of this water source, near areas with the highest lithium concentration, could streamline the development of production facilities and evaporation ponds, potentially reducing both capital and operating costs.

Gabriel Rubacha, NOA’s Chief Executive Officer, emphasized the importance of this discovery, noting its alignment with the company’s preliminary assessment for locating a production facility. The water well, drilled to a depth of 190 meters, is situated in the northern section of the project, close to identified high lithium concentration areas. This discovery is one of three fresh water targets at Rio Grande, indicating potential for further water resource expansion.

NOA Lithium’s strategic position in the Lithium Triangle, with over 140,000 hectares across three prospective salars, places it among industry leaders in one of Argentina’s most mining-friendly jurisdictions. The company’s progress, including this water discovery and the upcoming Preliminary Economic Assessment (PEA) in Q3 2025, underscores its potential to become a significant lithium producer. With global lithium demand on the rise, driven by electric vehicle adoption and energy storage needs, NOA’s advancements at the Rio Grande Project highlight its emerging role in the lithium supply chain.
