Cautionary Statement Regarding Mineral Resources

The mineral resources disclosed in this press release conform to NI 43-101 standards and guidelines and were prepared by an independent qualified person. The above-mentioned mineral resources are not mineral reserves as they do not have demonstrated economic viability. The quantity and grade of the reported Inferred Mineral Resources are conceptual in nature and are estimated based on limited geological and hydrogeological evidence and sampling. Existing data are sufficient to imply but not verify mineral grade and/or quality of continuity. An Inferred Mineral Resource has a lower level of confidence relative to a Measured or Indicated Mineral Resource and constitutes an insufficient level of confidence to allow conversion to a Mineral Reserve. It is reasonably expected, but not guaranteed, that the majority of Inferred Mineral Resources could be upgraded to Measured or Indicated Mineral Resources with additional drilling and pump tests.

Stellantis Investment and Off-take

In September 2023, Argentina Lithium & Energy Corp. entered into a definitive agreement with Stellantis, a leading global automaker, for a strategic investment through Stellantis' subsidiary Peugeot Citroen Argentina S.A., in return for a 19.9% stake in ALE, with Argentina Lithium retaining 80.1%. The agreement includes an Exchange Right allowing Stellantis to convert its ALE shares into up to 19.9% of Argentina Lithium's common shares (undiluted), subject to certain conditions and a Top-Up Right to maintain that ownership threshold. Additionally, the parties executed a seven-year lithium offtake agreement, under which Stellantis will have the right to purchase up to 15,000 tonnes of lithium carbonate per year, if and once commercial production begins, with options for extension and rights of first refusal on surplus product.

Qualified Persons and QA/QC

The Mineral Resource Estimate and technical data in this news release were prepared under the direction of Frederik Reidel, CPG, of Atacama Water Consultants. Mr. Reidel is an independent Qualified Person ("QP") as defined in NI 43-101. Mr. Reidel reviewed drill and brine sample collection, handling, and security practices for all drilling and sampling campaigns. All conform to industry best practice. The QP has reviewed and approved the technical content of this news release.
