PRESS RELEASE

Critical Elements Lithium increases its confidence in Rose Project Growth as New

Discoveries Expand Known Pegmatite Swarm

September 12th, 2023 – MONTRÉAL, QUÉBEC – Critical Elements Lithium Corporation (TSX -V: CRE) (US

OTCQX: CRECF) (FSE: F12) ( "Critical Elements" or the "Corporation") is pleased to announce that,

since the restart of exploration work on the Rose Lithium-Tantalum Project (“Rose” or “Project”), located in

the Eeyou Istchee -James Bay region of Quebec, field crews have successfully discovered several new

spodumene-bearing pegmatite outcrops.

As outlined in the news release dated September 5, 2023, Critical Elements has recommenced ground

exploration focused on defining drill targets for a significant fall and winter drill program. Multiple rigs will be

deployed to drill-test new targets. The Rose project is situated within the Rose and Rose South claim blocks

(Figure 1), which constitute 395 km2, or only 38 % of the 1,050 km2 in the Corporation’s highly prospective

exploration portfolio in Québec. It is important to note that the Rose project mineral resource estimate is

based largely on drilling that concluded in 2016 as management focused on delivering technical studies

and advancing permitting at that time.

Several new discovery areas have been identified in the Rose pegmatite swarm. To date, four spodumene-

bearing pegmatite outcrops have been identified in the New Discovery Area. At this early stage, the strike

length, width and orientations of these dykes is unknown but the apparent strike length along the outcrops

exceeds 330 metres. The exploration team is planning to follow up with more work on the area over the

next few days.

Jean-Sébastien Lavallée, CEO of Critical Elements Lithium commented , “Today’s announcement is an

important milestone for Critical Elements as we reaccelerate exploration in the vicinity of the Rose deposit.

Furthermore, with more than 3 95 km2 of property a t Rose and Rose South , multiple highly prospective

areas potentially within trucking distance of the proposed Rose concentrator remain to be explored in the

next few weeks.”
