NOA ENGAGES HATCH TO LEAD PROCESS DEVELOPMENT STUDY TO SUPPORT UPCOMING PFS AT RIO GRANDE PROJECT

NOA Lithium Brines Inc. has appointed Hatch Ltd. to lead a process development study for the company's flagship Rio Grande project in Salta province, Argentina. Hatch is a global multidisciplinary project management, engineering and professional service consultancy with extensive experience in critical minerals, and has substantial experience in processing and engineering of lithium rich brines, including projects located on salars in Argentina.

The objective of the study is to compare the project's baseline evaporation pond flow sheet against alternative process configurations incorporating direct lithium extraction technology. The study is expected to be completed in two stages: (i) DLE testwork and evaluation; and (ii) development of concept-level process design and operating assumptions to enable comparison of alternative flow sheets. The study is intended to inform the scope and design basis for NOA's coming preliminary feasibility study.

The study is expected to be completed within the next three months, subject to testwork progress and results, with findings anticipated in third quarter 2026. The results are expected to provide insights into potential process optimization opportunities and development flexibility for the project and to support a robust prefeasibility study design basis.

NOA's chief executive officer, Gabriel Rubacha, stated: "This marks another step to get to Rio Grande's PFS. This study will help us evaluate process alternatives and refine our development pathway for Rio Grande ahead of the PFS. Hatch brings deep experience in lithium brine processing, and the results will support a more robust PFS design basis."

About NOA Lithium Brines Inc.

NOA is a lithium exploration and development company formed to acquire assets with significant resource potential. All NOA's projects are located in the heart of the prolific Lithium Triangle in the mining-friendly province of Salta, Argentina, near a multitude of projects and operations owned by some of the largest players in the lithium industry. NOA has rapidly consolidated one of the largest lithium brine claim portfolios in this region that is not owned by a producing company, with key positions on three prospective salars, being Rio Grande, Arizaro and Salinas Grandes, and totalling over 140,000 hectares. The Rio Grande project is NOA's flagship asset, with a resource estimate of approximately 4.7 million tons of lithium carbonate equivalent at an average lithium concentration of 525 milligrams per litre. In December, 2024, NOA completed final property payments on its Rio Grande project, securing 100-per-cent ownership of all claims within this project.
