NOA Lithium Announces Brine Processing Results

In This Article:

NOA Lithium Brines Inc. (TSX-V:NOAL)(FSE:N7N) (" NOA " or the " Company ") is pleased to provide an update on the significant progress of its flagship, Rio Grande Project (the " Rio Grande Project " or the " Project "). The Company has sent brine samples from the Project to a select few direct lithium extraction (" DLE ") supplies, of which XtraLit Ltd. (" XtraLit ") was one. XtraLit has a patented DLE process based on ion-exchange technology which consists of sorption, washing, desorption and post-desorption washing steps to process the brine. XtraLit completed its initial process test-work using its patented DLE technology on brine samples from the Company's Rio Grande's Project and provided promising initial results.

Highlights of the XtraLit results include:

  • Results: The outcome of XtraLit's DLE technology using its proprietary process recovered more than 91% of the lithium contained in the brine samples from Rio Grande.

  • Testing: Additionally, XtraLit's technology was very selective and effective in the extraction of lithium and the rejection of impurities (>98%) like magnesium, sodium, chlorine and others.

NOA's Chief Executive Officer, Gabriel Rubacha states: "Our Rio Grande Project already demonstrated the potential with a robust resource of 4.7 million tons of lithium carbonate equivalent at 525 milligrams per litre, which gives NOA the flexibility to develop the project using evaporation or DLE processes. Results received from XtraLit together with a recent announcement from Litica whereby they used an evaporation process to produce lithium carbonate from brines from the Rio Grande salar at its pilot plant, continue to confirm the potential of our flagship project. We continue the development of the project with the target of a Preliminary Economic Evaluation (PEA) of the Project during 2025."

DLE Process Evaluation

NOA has been working with a select few DLE providers. Results received from XtraLit show high recovery and rejection rates (>91% and >98% respectively).

As shown in the process flow below, brine sent to be tested in XtraLit's facilities contained 458 milligrams per litre and the eluate released contained 4,400 milligrams per litre of lithium concentration, which demonstrated the potential of the process for our Rio Grande Project.
