Critical Elements Lithium increases its confidence in Rose Project Growth as New Discoveries Expand Known Pegmatite Swarm

Critical Elements Lithium Corporation (TSXV: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 395 km² of property at 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."

The reader is cautioned that pictures and grab samples are selective by nature and may not represent average grades of the mineralization in the pegmatites.

The surface exploration program with five crews continues to ground-truth several LCT-pegmatite targets. Results will be released in context as the program progresses. Management is currently engaged in designing a significant fall and winter drill program with multiple rigs to drill-test new targets including the Duval discovery, advance the Lemare deposit, and expand the Rose project resource inventory including potential proximal satellite mineralization. Details of this extensive program will be forthcoming near-term.

About Critical Elements Lithium Corporation

Critical Elements aspires to become a large, responsible supplier of lithium to the flourishing electric vehicle and energy storage system industries. To this end, Critical Elements is advancing the wholly-owned, high-purity Rose lithium project in Québec, the Corporation's first lithium project to be advanced within a land portfolio of over 1,050 km². On August 29, 2023, the Corporation announced results of a new Feasibility Study on Rose for the production of spodumene concentrate. The after-tax internal rate of return for the Project is estimated at 65.7%, with an estimated after-tax net present value of US$2.2B at an 8% discount rate. In the Corporation's view, Québec is strategically well-positioned for US and EU markets and boasts good infrastructure including a low-cost, low-carbon power grid featuring 94% hydroelectricity. The project has received approval from the Federal Minister of Environment and Climate Change on the recommendation of the Joint Assessment Committee, comprised of representatives from the Impact Assessment Agency of Canada and the Cree Nation Government and also received the Certificate of Authorization pursuant to section 164 of Québec's Environment Quality Act from the Québec Minister of the Environment, the Fight against Climate Change, Wildlife and Parks.
