NEWS RELEASE
Critical Elements and GoldSpot Discoveries identify Lithium-Tantalum
targets at the Critical Elements claims in the Nemiscau belt using Artificial
Intelligence
GoldSpot Discoveries Corp.’s proprietary approach of Artificial Intelligence (AI) and
geological interpretation highlight Lithium-Tantalu m potential at the New Block 1-6 and 7
claims within the Nemiscau greenstone belt;
A total of 19 high to moderate prospectivity Lithi um-Tantalum targets were identified;
Nickel-Copper and Gold potential was also revealed ;
Critical Elements boasts a unique and favorable la nd position proximal to the Whabouchi
Lithium-Tantalum deposit, which opens up potential for new discoveries.
September 7, 2021 - M ONTREAL , QUEBEC – Critical Elements Lithium Corporation (the “ Company ”
or “ Critical Elements ”) (TSX-V: CRE) (US OTCQX: CRECF) (FSE: F12) mandat ed GoldSpot
Discoveries Corp. (TSX-V: SPOT) (OTCQX: SPOFF) (“Go ldSpot“) to conduct a remote targeting
process for lithium and tantalum, and nickel-copper and gold, on the New Block 1-6 and 7 claims
within the prolific Nemiscau belt (Figure 1). GoldS pot uses cutting edge technology and
geoscientific expertise to mitigate exploration risks and make mineral discoveries.
This study hinged on digital extraction from an exh austive 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.
The compilation of discrete outcrop observations al lowed a reliable update to existing geologic
maps, resulting in a refined pegmatite map including metamorphic domains. A total of 42 pegmatite
bodies were added to the current geological map, hi ghlighting previously unknown potential for
economic lithium-tantalum mineralization. An up to date structural interpretation was created based
on a high-resolution aeromagnetic survey commissioned by Critical Elements. This survey revealed
structurally complex patterns, including large-scal e folds and major ENE-trending ductile fault
zones.
GoldSpot generated lithium-tantalum, copper-nickel and gold focused targets. These target areas
were generated using a knowledge based approach wit h Artificial Intelligence (AI) data-driven
methods. The AI data analysis trains machine learning algorithms to predict the presence of lithium-
tantalum (model 1), copper-nickel (model 2), and gold (model 3), using all variables (features), both
numeric and interpreted on a 10 x 10 m grid cell da tacube. Once the model performs to a
satisfactory level, results produced include: 1) a series of zones with relatively high probability of
containing lithium and tantalum (model 1; same process for models 2 and 3); 2) a ranking of feature
importance for each input feature.
The best prediction model for the lithium-tantalum model was obtained using a Random Forest
classifier for which performance metrics were above 80% precision. The updated lithology and
structural interpretation were the dominant contributors to the targeting model.

A total of 19 lithium-tantalum exploration targets were identified (Figure 2), reducing the area of
investigation to approximately 16% of the total cla im holding. These targets highlight the outer
zones of felsic batholiths as the most prospective areas of the claims, including ENE trends at both
northern and southern margins of the pertained claims.
A total of 5 copper-nickel and 7 gold targets were also identified (Figure 2). These targets commonly
occur in similar geological settings: areas of intense structural complexity where a diversity of rock
units occurs, including mafic units, felsic intrusions and paragneiss.
In addition to the targeting, GoldSpot provided a map of probable outcrop zones to support future
field programs. More than 75% of the existing outcrops were found by the machine learning model,
highlighting the predictive accuracy of this approa ch. The machine learning-assisted outcrop
detection allows for time- and cost-efficient field exploration.
The area of interest occurs in the southeastern par t of the Nemiscau Subprovince. The northern
Nemiscau Subprovince is marked by the volcano-sedim entary rocks of the Lac des Montagnes
Group which consists of mafic to felsic volcanic units and iron formations. These Archean volcanic-
sedimentary packages are affected by major NE-trend ing ductile shear-zones (Pedreira et al.,
2020) during the Kenoran orogeny (2720 - 2680 Ma). Local geology exposures include
metamorphosed sediments units (i.e., paragneiss fro m the Rupert Complex and Voirdye
Formation), syn-tectonic intrusives (i.e., De la Hu tte Complex and The Canard Suite) and post-
tectonic pegmatites (i.e., Mezière Suite and Spodumène Suite).
“Although Critical Elements’ primary focus is on advancement of the Rose project through detailed
engineering for Phase I and delivery of advanced te chnical studies for Phase II, the Company is
making plans to follow up the prioritized Smart tar gets generated. Ground-truthing followed by
surface-sampling and drill-testing are contemplated. This is consistent with our aspiration to be a
large, responsible supplier of lithium, enjoying th e inherent advantages of our host jurisdiction of
Quebec,” said Jean-Sébastien Lavallée, Chief Executive Officer of the Company.

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, high purity Rose lithium project in Quebec. Rose is the
Company’s first lithium project to be advanced within a highly prospective land portfolio of over 700
square kilometers. In 2017, the Company completed a robust feasibility study on Rose Phase 1 for
the production of high quality 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 201 9 by Primero Group in the context of a
Guaranteed Maximum Price under an Early Contractor Involvement agreement, as a prelude to an
Engineering, Procurement and Construction process. Detailed engineering for Phase I is expected
to conclude this year as the Company plans to deliver technical studies for Phase II; the conversion
of spodumene concentrate to high quality lithium hy droxide. In the Company’s view, Quebec is
strategically well-positioned for US and EU markets and boasts exceptional infrastructure including
a low-cost, low-carbon power grid featuring 93% hyd roelectricity. The project has received
approval from the Federal Minister of Environment and Climate Change on the recommendation of
the Joint Assessment Committee, comprised of repres entatives from the Impact Assessment
Agency of Canada and the Cree Nation Government; we await similar approval under the Quebec
environmental assessment process near-term. The Com pany also has a strong, formalized
relationship with the Cree Nation.
