PRESS RELEASE
CRITICAL ELEMENTS LITHIUM CONTINUES TO EXPAND MAJOR DISCOVERY AT ROSE WEST WITH
ADDITIONAL MULTIPLE WIDE LITHIUM-RICH INTERCEPTS
HIGHLIGHTS:
- 1.39% Li2O and 157 ppm Ta2O5 over 35.30 m, including 2.33% Li2O and 152 ppm Ta2O5 over
9.00 m in hole RD-24-25A
- 1.29% Li2O and 121 ppm Ta2O5 over 31.50 m, including 1.69% Li2O and 127 ppm Ta2O5 over
13.50 m in hole RD-24-24
- 1.22% Li2O and 250 ppm Ta2O5 over 20.50 m, including 1.60% Li2O and 181 ppm Ta2O5 over
15.00 m in hole RD-24-17

- 1.59% Li2O and 127 ppm Ta2O5 over 13.80 m in hole RD-24-18
- 1.75% Li2O and 201 ppm Ta2O5 over 10.10 m in hole RD-24-19
April 22th, 202 4 - MONTRÉAL, QUÉBEC – Critical Elements Lithium Corporation (TSX -V: CRE) (US
OTCQX: CRECF) (FSE: F12) ("Critical Elements" or the "Corporation") is pleased to announce the most
recent results from the winter 31-hole, 3,670-meter drill program on its 100% owned Rose West Discovery
with multiple wide intersections of lithium-rich pegmatites.
The Rose West Discovery (“Rose West”) is situated within the Rose Lithium-Tantalum and Rose South
property blocks (Figure 1), which constitute 395 km2, or only 38% of the total 1,050 km2 in the Corporation’s
highly prospective exploration portfolio in Québec.
The 2024 winter drill campaign successfully completed 3,670 meters of drilling in 3 1 holes on the
spodumene-bearing pegmatite showings discovered during the 2023 summer prospecting campaign,
herein referred to as Rose West. Drilling results to date have demonstrated the continuity of a mineralized
pegmatite body, which thus far extends over 450 m strike, 370 m down dip and to a vertical depth of 140
m. In the west, the body is comprised of multiple near surface mineralized pegmatites that range up to an
apparent thickness of 12.40 m individually. These bodies appear to coalesce into a more substantial
spodumene-bearing pegmatite in the east with an apparent width of up to 40.4 0 m. The near surface
pegmatites appear to strike northwesterly with a gentle dip of 15 °, while the thicker pegmatite appears to
strike easterly with a near -horizontal dip of 13 °. The body is still open in all directions, while the greatest
exploration potential appears to be to the east.
New assay results from the drill program have been received for fourteen new drillholes. Several of the new
drillhole results returned wide high grade lithium assays, as highlighted:
- 1.39% Li2O and 157 ppm Ta2O5 over 35.30 m, including 2.33% Li2O and 152 ppm Ta2O5 over
9.00 m in hole RD-24-25A
- 1.29% Li2O and 121 ppm Ta2O5 over 31.50 m, including 1.69% Li2O and 127 ppm Ta2O5 over
13.50 m in hole RD-24-24
- 1.22% Li2O and 250 ppm Ta2O5 over 20.50 m, including 1.60% Li2O and 181 ppm Ta2O5 over
15.00 m in hole RD-24-17
- 1.27% Li2O and 192 ppm Ta2O5 over 18.65 m in hole RD-24-27
- 1.59% Li2O and 127 ppm Ta2O5 over 13.80 m in hole RD-24-18
- 1.75% Li2O and 201 ppm Ta2O5 over 10.10 m in hole RD-24-19

A summary of the new assay results is presented in Table 1 and in Figures 2 to 7 . A summary of the
previously announced assay results is presented in Table 2 and in Figures 2 to 7.
“With the complete results of the Rose West winter program, we recognize the opportunity to add
significantly to the Rose Project’s resource inventory and, potentially, augment its mine life and already
robust economic appeal,” commented Chair of the Board Eric Zaunscherb. “As a reminder, the Rose
Lithium-Tantalum Project Feasibility Study published in August 2023 ( see press release dated August 23,
2023) returned an after-tax NPV8% of US$2.2B and an after-tax IRR of 65.7%. The next step is a second-
round drill program, currently being planned, followed by an initial mineral resource estimate if warranted.
In the interim, management sees no reduction in urgency on the part of lithium end -users to see quality
spodumene concentrate sourced from a world-class jurisdiction flow into their supply chains. Québec, with
its clean grid and exceptional regulatory standards, is well-regarded globally.”
