NEWS RELEASE

Critical Elements and Lomiko Metals identify Bourier project lithium targets

and report discoveries using GoldSpot Discoveries’ Artificial Intelligence

methods

 GoldSpot Discoveries Corp.’s proprietary approach of Artificial Intelligence (AI) and

geological interpretation highlight lithium potenti al at Bourier claims within the Nemiscau

greenstone belt;

 A total of 15 high to moderate prospectivity lithi um targets have been identified;

 Preliminary Summer 2021 field exploration results have revealed the discovery of five (5)

new sectors of spodumene-rich (Li) pegmatites, high lighting the potential of the Bourier

project;

 Critical Elements and Lomiko Metals (Option Agreem ent, see press release dated April

27, 2021 ) boast a unique and favorable land position for li thium exploration within the

Nemiscau Belt.

September 14, 2021 - M ONTREAL , QUEBEC – Critical Elements Lithium Corporation (the

“Company ” or “Critical Elements ”) (TSX-V: CRE) (US OTCQX: CRECF) (FSE: F12) and Lomiko

Metals (TSX-V: LMR.V) mandated GoldSpot Discoveries Corp. (TSX-V: SPOT) (OTCQX:

SPOFF) (“GoldSpot“) to conduct a remote targeting p rocess for lithium, on the Bourier claims

within the Nemiscau belt (Figure 1). GoldSpot uses cutting edge technology and geoscientific

expertise to mitigate exploration risks and make mineral discoveries.

Methodology

The study hinged on digital extraction from an exha ustive collection of compiled data, including

assessment files, government data and academic stud ies. This dataset provided outcrop/sample

description, bedrock geology, geochemical analyses, and geophysical surveys. Original data was

cleaned and combined to create a comprehensive data set for geological interpretation and

machine learning processes.

Geological Interpretation

 The compilation of discrete outcrop observations a llowed a reliable update to existing

geologic maps, resulting in a refined, lithium expl oration-oriented pegmatite map. A total

of 99 pegmatite bodies were added to the current ge ological map, highlighting previously

unknown potential for economic lithium mineralization.

 An up-to-date structural interpretation was create d based on a high-resolution

aeromagnetic survey commissioned by Critical Elemen ts. This survey revealed

structurally complex patterns, including large-scale folds and major ENE-trending ductile

fault zones.

Lithium Target Generation

GoldSpot generated lithium targets using a knowledg e-based approach with Artificial Intelligence

(AI) data-driven methods.

 Process: The AI data analysis trains machine learn ing algorithms to predict the presence

of lithium using all variables (features), both num eric and interpreted on a 10 x 10 m grid

cell datacube. Once the model performs to a satisfactory level, results produced include:

1) a series of zones with relatively high probability of containing lithium;

2) a ranking of feature importance for each input feature.

 Performance: The best prediction model for lithium at Bourier was obtained using the

Extended Euclidean Algorithm for which performance metric was at 75% precision. The

updated lithology and structural interpretation wer e the dominant contributors to the

targeting model.

Metals’ Bourier project on the Northeastern part of the Nemiscau belt.

 Results: A total of 15 lithium exploration targets were identified (Figure 2), reducing the

area of investigation to approximately 9.5% of the total claim holding. The newly

interpreted pegmatite outcrops largely controlled the distribution of the lithium targets.

Field Work and Preliminary Results

In preparation of field work, GoldSpot provided a m ap of probable outcrop zones, resulting from

the AI analysis on high-resolution satellite imager y. The machine learning-assisted outcrop

detection allows for time- and cost-efficient field exploration.

An exploration crew composed of Critical Elements’ and GoldSpot’s geoscientists conducted a

20-day prospecting program at the Bourier project, with focus on the high- to moderate-

confidence lithium targets generated by GoldSpot. T he highlights of this program include the

discovery of five (5) new sectors of spodumene-rich (Li) pegmatite (laboratory analysis results are

pending; Figure 2). These discoveries were made within, or the extension, of GoldSpot’s targets.

The main discovery, located about 11 km NE of the B ourier Lake, consists of muscovite and

garnet pegmatites showing 1-5% of centimetric-size spodumene crystals (Figure 3), over an

outcropping area of 40 x 30 m. Additional spodumene -rich pegmatites were sporadically found

within a 1 km trend from the main discovery, highli ghting the potential for wider mineralization

system. Four other spodumene-rich pegmatites zones were found elsewhere on the property.

Jean-Sébastien Lavallée, Chief Executive Officer of the Company, noted, “We are confident that

continued exploration, benefitting from the deploym ent of GoldSpot’s AI analysis and our joint

geoscientific expertise, will continue to reveal th e considerable potential of the Bourier property.

We anticipate that this approach may yield similar results on the rest of the Company’s

exploration project portfolio, working towards our aspiration to be a large, responsible supplier of

lithium. Our primary focus remains on the advancement of the Rose lithium-tantalum project, our

first.”

ABOUT CRITICAL ELEMENTS LITHIUM CORPORATION

Critical Elements Lithium Corporation aspires to become a large, responsible supplier of lithium to

the flourishing electric vehicle and energy storage system industries. To this end, Critical

Elements Lithium is advancing the wholly owned, hig h purity Rose lithium project in Quebec.

Rose is the Company’s first lithium project to be a dvanced within a highly prospective land

portfolio of over 700 square kilometers. In 2017, t he Company completed a robust feasibility

study on Rose Phase 1 for the production of high qu ality spodumene concentrate. The internal

rate of return for the Project is estimated at 34.9% after tax, with a net present value estimated at

C$726 million at an 8% discount rate. Capital cost parameters were confirmed in 2019 by Primero

Group in the context of a Guaranteed Maximum Price under an Early Contractor Involvement

agreement, as a prelude to an Engineering, Procurem ent and Construction process. Detailed

engineering for Phase I is expected to conclude thi s year as the Company plans to deliver

technical studies for Phase II; the conversion of s podumene concentrate to high quality lithium

hydroxide. In the Company’s view, Quebec is strategically well-positioned for US and EU markets

and boasts exceptional infrastructure including a l ow-cost, low-carbon power grid featuring 93%

hydroelectricity. The project has received approval from the Federal Minister of Environment and

Climate Change on the recommendation of the Joint A ssessment Committee, comprised of

representatives from the Impact Assessment Agency o f Canada and the Cree Nation

Government; we await similar approval under the Que bec environmental assessment process

near-term. The Company also has a strong, formalized relationship with the Cree Nation.
