PRESS RELEASE

Critical Elements Lithium Identifies New LCT Pegmatite Targets and Announces a

Surface Exploration Program in the Nemaska Belt Portfolio

May 31 st, 2023 - MONTRÉAL, QUÉBEC – Critical Elements Lithium Cor poration (TSX-V: CRE) (US

OTCQX: CRECF) (FSE: F12) ( "Critical Elements" or the "Company" ) is pleased to report the

identification of new lithium-cesium-tantalum pegma tite (“LCT pegmatite ”) trends following advanced

geochemical interpretations made by ALS GoldSpot Discoveries Ltd. (“ALS GoldSpot”), and announces a

surface exploration program at Duval, Lemare, Valiquette, Arques, Caumont, Dumoulon, New Block 1 to 6,

Rose and Rose Nord properties.

Critical Elements has actively explored its Nemaska belt properties (Figure 1) since 2021, which led to the

discovery in 2022 of new multi-kilometre-long LCT pegmatite prospective trends on the Company’s 100%

owned Lemare and Duval properties ( see press release dated October 27, 2022 ). Following the 2022 field

program, the Company mandated ALS GoldSpot to conduct a geochemical interpretation of the Company’s

multi-element rock sample data, along with legacy geochemical data, for exploration vectoring.

Geochemical Vectoring

A total of 3,900 surface rock samples were collecte d in 2021 and 2022, and then prepared by four-acid

digestion and analyzed by ICP-MS61 for 47 elements at ALS Laboratory in Val d’Or. Geochemical vectoring

effectively isolated fertile pegmatite suites from unprospective rock samples.

ALS GoldSpot applied a signal enhancement and denoi sing technique coupled with a density-based

clustering method on selective immobile elements – lithium, cesium, tantalum elements were not include d

- to characterize geochemical populations. This approach isolated a unique geochemical signal associated

with mineralized LCT pegmatite without considering lithium, cesium or tantalum as input elements, and

resulted in the identification of 162 pegmatite samples.

The distribution of fertile LCT pegmatite environme nts is consistent with interpreted major SW-NE

structures that span the Company’s Nemaska belt properties (Figure 2). The geochemical approach offers

a new outlook on the multi-elements geochemical database to orient early lithium exploration.

2023 Surface Exploration Program

The Company announces a surface exploration program focussed on prospecting the identified fertile

pegmatite environments. Starting early June, the 12 -week program will consist of prospecting, mapping

and trenching. The Company has mandated ALS GoldSpo t to manage the 2023 exploration program, in

collaboration with the Company’s teams. Following the surface exploration program, the results will inform

a drill program designed to confirm in three dimensions the discovery of new spodumene-bearing pegmatite

bodies.

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, hi gh

purity Rose lithium project in Québec, the Corporat ion’s first lithium project to be advanced within a land

portfolio of over 1,000 square kilometers. On June 13 th , 2022, the Corporation announced results of a

feasibility study on Rose for the production of spodumene concentrate. The after-tax internal rate of return

for the Project is estimated at 82.4%, with an esti mated after-tax net present value of US$1.9 B 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, lo w-carbon power grid featuring 94% hydroelectricity. The

project has received approval from the Federal Mini ster of Environment and Climate Change on the

recommendation of the Joint Assessment Committee, c omprised of representatives from the Impact

Assessment Agency of Canada and the Cree Nation Gov ernment 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.
