NOA Engages Hatch To Lead Process Development Study To Support
Upcoming PFS At Rio Grande Project
May 5, 202 5, Buenos Aires, Argentina – NOA Lithium Brines Inc. (TSXV:NOAL |
Frankfurt:N7N) (“NOA” or the “Company”) is pleased to announce the appointment of Hatch
Limited (“Hatch”) to lead Process Development Study (“Study”) for the Company’s flagship
Rio Grande Project (the “ Project”) in Salta Province, Argentina. Hatch is a global
multidisciplinary project management, engineering and professional services 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 flowsheet
against alternative process configurations incorporating direct lithium extraction (“ DLE”)
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 parameters
to enable comparison of alternative flowsheets. The Study is intended to inform the scope
and design basis for NOA’s upcoming preliminary feasibility study (“PFS”).
The Study is expected to be completed within the next three months, subject to testwork
progress and results, with findings anticipated in Q3 2026. The results are expected to
provide insights into potential process optimization opportunities and development flexibility
for the Project, and to support a robust PFS design basis.
NOA’s Chief Executive Officer Gabriel Rubacha states: “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.”
