Warning regarding mineral resources

The mineral resources mentioned in this press release comply with NI 43-101 standards and guidelines and have been prepared by an independently qualified person. The above-mentioned mineral resources are not mineral reserves as they have not demonstrated economic viability. The quantity and quality of reported inferred mineral resources are conceptual in nature and are estimated from limited geological and hydrogeological evidence and sampling. Existing data are sufficient to imply, but not verify, mineral grade and/or continuity quality. An inferred mineral resource has a lower confidence level compared to a measured or indicated mineral resource and does not constitute an insufficient confidence level to allow conversion to a mineral reserve. It is reasonably expected, but not guaranteed, that the majority of inferred mineral resources can be upgraded to measured or indicated mineral resources with additional drilling and pumping testing.

Stellantis Investment and offtake

In September 2023Argentina Lithium & Energy Corp. entered into a definitive agreement with Stellantis, a leading global automotive manufacturer, for a strategic investment through Stellantis’ subsidiary Peugeot Citroen Argentina SA, in exchange 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 common stock (undiluted), subject to certain conditions, and a top-up right to maintain that ownership threshold. In addition, the parties have entered into a seven-year lithium offtake agreement, under which Stellantis will have the right to purchase up to 15,000 tons of lithium carbonate per year, if and when commercial production begins, with extension options and rights of first refusal on excess product.

Qualified persons and QA/QC

The mineral resource estimate and technical data contained in this press release were prepared under the direction of Frederick ReidelCPG, from Atacama Water Consultants. Mr. Reidel is an independent qualified person (“QP“) as defined in NI 43-101. Mr. Reidel reviewed the collection, handling and safeguarding practices of drilling and brine samples for all drilling and sampling campaigns. All are in accordance with industry best practices. The QP has reviewed and approved the technical content of this press release.
