PRESS RELEASE
CRITICAL ELEMENTS CONFIRMS NICKEL-COPPER-COBALT-PGE POTENTIAL ON THE
NEMASKA BELT PROPERTIES, WITH RESULTS UP TO 2% Cu, 0.76% Ni, 0.07% Co,
3.38 g/t Pt and 0.62 g/t Pd
September 11th, 2025 - MONTRÉAL, QUÉBEC – Critical Elements Lithium Corporation (TSX-V: CRE) (US
OTCQX: CRECF) (FSE: F12) ( "Critical Elements" or the "Corporation”) is pleased to announce initial
results from the 2025 summer exploration program completed on Critical Elements’ 100%-owned Nemaska
Belt properties group, in the Eeyou Istchee region of Québec (Figure 1).
An important helicopter-borne electromagnetic VTEM plus time-domain system (“VTEM”) survey covering
the Nemaska Belt properties was designed to provide data incremental to the high-resolution magnetic
survey completed in 2021 . These datasets aided the exploration team ’s surface program targeting
potentially economic mineralization , including high-grade nickel-copper-PGE and lithium-bearing
spodumene.
Interest in high-grade nickel-copper-PGE mineralization in the region has increased with the exploration
success of Power Metallic Mines Inc. (“Power Metallic”), formerly Chilean Metals Inc. Critical Elements
optioned the Nisk property to Power Metallic in 2020 (press release). Following the exercise of the option
agreement by Power Metallic on the property hosting the Ni-Cu-EGP Nisk deposit and the new polymetallic
Lion discovery, Critical Elements retains a non -dilutive interest of 20% until a definitive feasibility study
regarding extraction and production activities is completed on the Nisk property. Critical Elements also held
just over 10 million shares of Power Metallic as of May 31, 2025 (Condensed Interim Financial Statements
for the nine-month period ending May 31, 2025).
Mineralized Zones
During the 2025 summer exploration program, multiple mineralized zones were identified through rock
sampling in areas coinciding with electromagnetic anomalies (VTEM conductors) . The mineralization is
dominated by pyrrhotite and p yrite (iron sulfide) with trace to 3-5% chalcopyrite (copper sulfide) and/or
pentlandite (iron-nickel sul fide). Surface exploration confirmed historical showings and identified newly
prospective areas.
In total, 1,091 rock samples and 73 till samples (0.5kg C -horizon) were collected during the summer
campaign, of which 452 rock samples assays are still pending. The exploration program was designed to
maximize geochemical coverage and assist in defining targets for future drill testing (Figures 1 and 2). Of
these samples:
- 25 grab samples grading above 0.1% nickel, with values up to 0.76% nickel.
- 17 grab samples grading above 0.1% copper, with values up to 2.00% copper
- 9 grab samples grading 0.1 g/t or above palladium, with values up to 0.62 g/t palladium
- 1 grab sample assaying 3.38 g/t platinum
- 6 grab samples grading over 0.025% cobalt, with values up to 0.07% cobalt
- 35 grab samples grading above 1.0 g/t silver, with values up to 13.6 g/t silver
- 2 grab samples assaying 0.32% and 0.22% molybdenum
*Grab samples are selective by nature, unlikely to represent average grades, and may not represent true underlying mineralization.

Critical Elements’ 100%-owned Nemaska Belt properties consist of 1,052 Exclusive Exploration Right
across ten different property bloc ks, covering a total of 540 km2. The portfolio spans over 100 km of the
Nisk structure and its associated volcano-sedimentary belt . Th is east-northeast-oriented belt features
recognized potential for lithium-associated pegmatite dyke s and copper, nickel, and PGE mineralization
associated with ultramafic rocks.
The Corporation expects to receive final assay results from the 2025 summer exploration program over the
next few weeks. All the results from th is surface program and previous geophysical surveys will be
incorporated to refine its planned 2026 winter drill program. This drill program will test the newly generated
high-grade nickel-copper-PGE and lithium-bearing spodumene drill targets. The program will also seek to
expand the mineralized footprint of the Rose West Discovery . Rose West lies within the 395 km² Rose
Lithium-Tantalum and Rose South property blocks and is located less than 10 km west of the Corporation’s
flagship Rose Lithium-Tantalum Project (see press release dated April 22, 2024). As a reminder, the Rose
Lithium-Tantalum Project Feasibility Study published in August 2023 ( see press release dated August 29,
2023) returned an after-tax NPV8% of US$2.2 billion and an after-tax IRR of 65.7%.
Management continues to be engaged in assembling the funding required to make a final investment
decision on the Rose project . These efforts build on the $20 million conditional funding from Natural
Resources Canada’s Critical Minerals Infrastructure Fund (see press release dated February 6, 2025) and
the support letter from a leading Canadian financial institution stating its interest in providing long term debt
financing of up to US$115 million (approximately C$150 million) of project debt ( see press release dated
February 10, 2025).

Quality assurance/quality control
Quality assurance and quality control procedures have been implemented to ensure best practices in
sampling and analysis of the samples. Standards and blanks were regularly inserted into the sample
stream. The samples were delivered in secure, tagged bags to the ALS Minerals laboratory facility in Val -
d’Or, Quebec. The samples are weighed and identified prior to sample preparation. Till samples were dried,
sieved to 63 μm and analyzed using four-acid digestion (ME-MS61L). Rock samples were crushed to 70%
minus 2 mm, then separated and pulverized to 85% passing 75 μm. Samples were assayed for a 33 -
elements suite using a four -acid digestion method (ME ICP 61) with re -assay of values over 10,000 ppm
for copper using a four -acid digestion and ICP finish (Cu -OG62). Gold, platinum and pal ladium were
analyzed by fire assay with an ICP -AES finish (PGM -ICP-27). Gold was analyzed using fire assay only,
when PGE mineralization was not suspected (Au-AA23).

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-Tantalum project in Québec, the Corporation’s first lithium project to be advanced within
a land portfolio of over 1,050 km 2. 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 represen tatives from the Impact
Assessment Agency of Canada and the Cree Nation Government, received the Certificate of Authorization
under the Environment Quality Act from the Québec Minister of the Environment, the Fight against Climate
Change, Wildlife and Parks, and the project mining lease from the Québec Minister of Natural Resources
and Forests under the Québec Mining Act.
