Figure 2: Localisation map of Drill Results of Rose Property

This phase of drilling has been valuable in providi ng more geotechnical data that will be incorporated into

the final mine plan. The tightened drill resolution has provided greater confidence in the resource bl ock

model on the eastern portion of the Rose deposit. A dditional drilling is planned later this year to te st the

northern extension of the deposit, as well as poten tial satellite spodumene-bearing pegmatites within 10

km.

A 5,554-meter, 31-hole winter drill program was conducted on the Lemare zone and data is being compiled.

Critical Elements intends to pursue further work on Lemare over the summer with surface mapping and a

sampling program follow by drilling. Lemare is well-situated within 3 km of road access and is an excellent

candidate for initial technical studies.

Quality assurance/quality control

Quality assurance and quality control procedures were implemented to ensure best practices in sampling

and analysis of the core samples. The drill core was logged and then split, with one-half sent for assay and

the other retained in the core box as a witness sam ple. Duplicates, standards, and blanks were regular ly

inserted into the sample stream. The core samples w ere delivered, in secure tagged bags, directly to t he

ALS Minerals laboratory facility in Val-d'Or, Quebe c. The samples are weighed and identified prior to

sample preparation. The samples are crushed to 70% minus 2 mm, then separated and pulverized to 85%

passing 75 μm. All samples are analyzed using sodium peroxide fusion ME-MS-89L, with full analysis for

52 elements. Value over 25,000 ppm Li were re-assays using Li-ICP-82b and value over 2,500 ppm Ta 2O5

were re-assays using Ta-XRF10.

Rose Lithium-Tantalum Project update:

The Corporation is pleased to report that the front-end engineering design (“FEED”) and value engineering

studies for the process plant and associated infrastructure were completed during the first quarter of 2023.

Bumigeme Inc. performed a gap analysis of the process plant, focusing on design review, optimization, and

risk mitigation for any potential issues with the p rocess flowsheet developed during the feasibility s tudy.

During the same period, WSP completed the FEED study for the infrastructure, surface water management,

mine water treatment plant, installation of the fin al effluent, main electrical station, 25 kV distrib ution,

utilities, service buildings and mining support facilities. Bumigeme Inc. and WSP completed these mandates

on schedule and within budget.

On completion of the gap analysis, Bumigeme Inc., B BA, WSP and other specialists in planning and

industrial processes commenced a new study with the aim of improving and freezing the 3D model layout

for all equipment and defining data sheets to fulfi ll long lead time equipment orders. WSP-Golder was

mandated to complete the detailed engineering design of the co-disposal facility for the filtered mill tailings

and waste rock from the open pit. Over 40% of WSP-Golder's mandate has been completed with completion

expected by the end of Q2 2023. Engineering work in cludes hazard classification, laboratory testing of

tailings, staging and placement, water management design, hydrogeological modeling, seepage collection,

stability assessment and an instrumented monitoring plan.

Furthermore, the Corporation announces the awarding of the detailed engineering mandate for the process

plant and the main electrical station to the BBA te am. It is important to note that BBA is very famili ar with

the Rose lithium and tantalum concentrator project. They carried out several audit and optimization

mandates on our project originally developed by Bumigeme Inc. and WSP. Thus, BBA will be able to ensure

a smooth transition to the execution of the detaile d engineering phases. In addition, BBA has extensiv e

multidisciplinary experience on previous mining pro jects, including several projects in northern Quebe c.

BBA will be an important player in the success of our project.

The Corporation is also proud to announce that all detailed engineering mandates have now been granted

to our partners WSP, BBA and InnovExplo. Critical E lements has all the necessary funds to complete the

detailed engineering phase. Overall engineering is progressing well, and we are over 35% complete. Key

engineering deliverables will be completed during t he summer period to allow, if project financing and

building permits are in place, to begin deforestation and initial preparation work by the end of the year.

Project Financing update:

As noted earlier this year ( see press release dated February 1 st , 2023 ) Critical Elements commenced a

formal process to receive and analyze multiple expressions of interest in participating in the financing and

development of the Rose Project. This process has a dvanced such that multiple parties have provided

comprehensive, non-binding expressions of interest to participate that compare favourably to the initi al

capital estimate outlined in the Project’s 2022 Fea sibility Study ( see press release dated June 13, 2022 ).

Critical Elements will continue to progress discuss ions with the leading parties, subject to negotiati ng

acceptable financing terms and conditions, as well as satisfactory due diligence and entering into the

required definitive documentation. Updates on this matter will be provided as appropriate.

The Corporation’s long-term strategy of avoiding Memorandum of Understandings for offtake arrangements

leaves the Rose Project’s planned production unencumbered in a tight market for spodumene concentrate,

both for chemical conversion for the burgeoning EV battery market and for the higher margin glass and

ceramics industry. Despite the recent correction in spot lithium markets, underlying market demand remains

robust in the face of supply-side sovereign, financ ial, and execution risks over the next several year s.

Conventional lithium concentrate projects in a top tier mining jurisdiction with major environmental permits

and an existing Impact and Benefits Agreement remain exceedingly rare.

Québec is recognized as a top mining jurisdiction with access to excellent infrastructure, as well as strong

financial and human capital. This makes the Rose Pr oject’s metallurgically attractive spodumene

concentrate highly desirable. Management is activel y engaged in identifying the optimal strategic part ner

or partners to maximize benefits for all the Corpor ation’s stakeholders, but at this time, there can b e no

guarantees as to the timing and outcome of this process.

Federal Budget:

Critical Elements expresses its satisfaction that t he Government of Canada has acknowledged the

significance of clean technology manufacturing by introducing a 30% investment tax credit (ITC) in its 2023

Budget, which can be refunded. The Corporation beli eves that a significant portion of the equipment

included in the 2022 Feasibility Study capital expenditures will be qualified for the newly introduced federal

tax credit.

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.
