In LEA XXVI brine is present in a surficial sequence of salt, which is underlain by sands and gravels, which vary in their degree of compaction and porosity. Drilling is not believed to have intersected tertiary terrestrial sediments, which are present around the salar margins, and potentially form the base of the salar. These southern drill holes have terminated in gravel units, which are believed to be alluvial fans, formed from sediment eroded from the salar margins and deposited within the salar, and later covered by salt. This is a pattern noted in many other salar basins.

The northern drill holes intersected a sequence of interbedded loose friable sands and compact gypsum sands, gravels, sands and occasional volcanic units across the LEA XXXIV, LEAI and LEAV properties on the west and east of the salar. These drillholes are in the northern part of the salar, within Catamarca province, north of the Antofalla village. Lithium concentrations in the northern properties were lower than those in the LEA XXVI property in the south of the salar, with lithium concentrations in the northern properties interpreted to be less concentrated than those in the center and south of the salar, which are interpreted as the nucleus of the salar. Lithium concentrations increased down hole from more dilute concentration around 100 mg/l Li, (with a low of 76 mg/L Li ) as near surface values, to a high of 189 mg/L downhole in DDH01-LEA 1, at 251-269 m.

The location of drill holes was based on previous time-domain/transient electromagnetics studies (the "TEM"). An extensive TEM survey was conducted over all the northern properties by geophysical contractor Quantec. TEM and MT was conducted in the LEA26 property by geophysical contractor GeoResource, to allow deeper imaging of the conductive brine unit, confirming it is hundreds of meters thick, and providing resolution of geological units at depth.

Samples were submitted with duplicate and standard samples, which show acceptable comparison between primary and duplicate samples and standard samples, compared to the certified standard concentration.

The technical content of this news release has been reviewed and approved by Mr. Murray Brooker, P. Geo., a consultant to the Company, and a qualified person as defined by National Instrument 43-101.

Table 2: Summary of brine chemistry from holes drilled by LEXI in the Antofalla South Project. Holes were drilled vertically and the sediments in the salar are flat lying. All thicknesses of brine mineralization delimited by the from to intervals in meters are true thicknesses. The extension of the brine is open at depth in the three holes in LEA XXVI, as bedrock to the salar is not believed to have been intersected.

Update on Credit Agreement

Further to the Company's press release dated March 7, 2025, the Company has not been able to arrange financing to repay the outstanding amounts under its secured credit facility with Arena Investors LP, for which it received a demand notice and notice of intention to enforce security pursuant to Section 244(1) of the Bankruptcy and Insolvency Act. The Company therefore has a large working capital deficit and there can be no assurance that its operations will continue in the current form, or at all.
