NOA Lithium Announces Strategic Collaboration with Hidrotec to Support NOA Projects

BUENOS AIRES, AR / ACCESS Newswire / May 12, 2026 / NOA Lithium Brines Inc. (TSXV:NOAL,OTC:NLIBF)(Frankfurt:N7N) ("NOA" or the "Company") is pleased to announce it has agreed to a strategic collaboration framework with Hidrotec S.A. ("Hidrotec"), one of Argentina's leading and most experienced drilling contractors in the lithium brine sector.

Under the collaboration, NOA expects to benefit from enhanced access to top quality drilling experience and equipment, with operational support for its planned work programs in Argentina. The collaboration is expected to commence with the first two rotary wells previously announced for NOA's flagship Rio Grande Project in Salta Province, Argentina. NOA and Hidrotec will operate under a transparent cost framework designed to support efficient execution of NOA's field activities. The parties may also explore additional forms of collaboration, including potential commercial participation, subject to further discussions and applicable approvals.

Hidrotec has been the strategic contractor for prolific lithium brine exploration and production projects in Argentina. Backed by more than 13 years of operational excellence, Hidrotec stands as the preeminent drilling contractor in northern Argentina. NOA views Hidrotec's extensive experience as a critical differentiator that enhances the contractor's technical capabilities and positions it to successfully execute the most demanding drilling operations.

NOA's Chief Executive Officer Gabriel Rubacha states: "Formalizing this collaboration with Hidrotec is an important step in strengthening our execution capacity in Argentina. We have worked successfully with Hidrotec since the early stages of the Company, and we believe their experience and access to equipment will provide additional flexibility as we advance our 2026 program at Rio Grande, including the currently planned rotary wells. We look forward to continuing to work together as we progress key technical work streams toward the Preliminary Feasibility Study. Hidrotec and Emiliano's commitment to NOA is a clear demonstration of the potential of the Rio Grande project, the Company, and their confidence in management."

Hidrotec's President Emiliano Gomez Martinez states: "We are pleased to formalize a collaboration with NOA and support the Company's 2026 program at Rio Grande. NOA has assembled a compelling lithium brine project portfolio, becoming one of the most promising companies in the actual market and we look forward to contributing our drilling capabilities and operational experience to help advance the project's next phase of work. We are deliberate in our choice of clients and operations, guided by an unwavering commitment to responsibility and integrity, values that define our reputation as a trusted partner in this industry."
