Comet Lithium Congratulates Winsome

Resources on its Maiden Mineral Resource

Estimate at Adina

Comet Lithium Liberty property located less than 700 meters

from known mineralization.

ROUYN-NORANDA, QC

,

Dec. 11, 2023

/CNW/ - Comet Lithium Corporation (TSXV: CLIC) (FSE:

8QY) ("Comet Lithium" or the "Corporation") congratulates Winsome Resources Limited

("Winsome") on the maiden Mineral Resource Estimate ("MRE") at its wholly-owned Adina Property

("Adina"), located in the Eeyou Istchee James Bay region of Québec and directly adjacent to Comet

Lithium's Liberty property (the "Liberty Property").

The MRE at Adina has established it as one of the largest lithium pegmatite mineral resource in the

Americas, returning 59 million tonnes at 1.12% Lithium Oxide ("Li

2

O") of Inferred Resources, at a

cut-off grade of 0.6% Li

2

O, for a total of 1.62 million tonnes contained lithium carbonate

equivalent

(1)

. The MRE is based on 27,600 meters of drilling at an approximate spacing of

100m

x

100m

. As reported by Winsome, it has 5 drill rigs now operating at Adina with over 25,000 meters of

additional infill and extensional drilling awaiting assay and targeting a MRE upgrade in H1 2024.

Winsome further confirms being well-funded to undertake over 50,000 meters of infill and step out

drilling in 2024 at Adina. Additionally, as reported by Winsome, the resource and geological

modelling has outlined significant potential for growth at Adina Main and Footwall Zones, which

remain open to the east and west along strike, up-dip to the north, and at depth. Recent results have

resulted in an increase in the strike length of mineralisation defined by systematic drilling to 1,340

meters as well as confirming the continuity of mineralisation between

Adina Main

and

Adina East

.

Comet Lithium's Liberty Property is directly adjacent to the Adina property with Winsome drill collars

located less than ~660 meters away from the property boundary. Additionally, Winsome has

identified pegmatite targets located less than 50 meters away from the Adina-Liberty claim border.

As previously announced, Comet Lithium has completed Phase 1 of the planned ground geophysical

gravity survey and has now initiated Phase 2 and Phase 3 of the gravity survey on its Liberty

Property. Comet Lithium expects to complete these two additional phases of the gravity survey by

mid-December. The gravity survey will assist in optimizing pegmatite drill targets across the Liberty

Property for the anticipated inaugural drill program.

"The release of the MRE on Adina by Winsome is a remarkable achievement, as it establishes the

Trieste formation as a top tier camp to focus on lithium exploration. The MRE release, combined

with Rio Tinto's recent Iceberg

discoveries

underpins the significant potential of the Trieste formation" commented Mr.

Vincent Metcalfe

,

Executive Chairman of Comet Lithium. "We are very excited to continue our systematic exploration

efforts at Liberty and anticipate completing the gravity survey by mid-December."

Qualified Person

Vincent Cardin-Tremblay

, P. Geo (ogq #1386, PGO #3347), registered in the Provinces of Québec,

and

Ontario

is Vice President Exploration to Comet Lithium, is a qualified person

under

National

Instrument 43

101

- Standards of Disclosure for Mineral Projects ("NI 43-101").

He has reviewed

the technical contents of this news release and has approved the disclosure of the technical

information contained herein.

About Comet Lithium Corporation

Comet Lithium is a dynamic lithium-focused exploration company active in the prolific

James Bay

District of

Quebec

. Comet Lithium's flagship asset is its 100%-owned Liberty Property contiguous to

Winsome Resources' Adina deposit, a growing high-grade discovery. Comet Lithium is advancing

Liberty to first-ever drilling.

Cautionary Note regarding the MRE

The MRE has been classified by Winsome as Inferred resources and reported in accordance with

the JORC Code, 2012 edition (the "JORC Code"). The JORC Code has been accepted for current

disclosure rules in

Canada

under NI 43-101. The meaning of mineral resources under the JORC

Code differs from that of the CIM Definition Standards. There are no technical report supporting the

MRE as this is not required under JORC Code. Readers must be aware that the technical

information relating to MRE has been obtained from a press release of Winsome dated

December

11, 2023

(the "Winsome Press Release") and such information has not been verified by the

Corporation's Qualified Person but is believed to be reasonably reliable. While Comet has

determined that the MRE is relevant to the Liberty Property given that the Liberty Property and

Adina property are adjacent to each other and Liberty Property is on strike with Andina's mineralized

pegmatites in addition that Winsome has identified pegmatite targets located less than 50 meters

away from the Adina-Liberty claim border. Readers are cautioned to not place undue reliance on the

MRE as it is not indicative of the mineralization of the Liberty Property and the MRE does not mean

or imply that economic deposits exist on the Liberty Property. Please refer to the Winsome's press

release dated

December 11, 2023

, for more details on the MRE.

Readers are also cautioned that mineral resources are not economic mineral reserves and that the

economic viability of resources that are not mineral reserves has not been demonstrated. The

estimate of mineral resources may be materially affected by geology, environmental, permitting,

legal, title, socio-political, marketing or other relevant issues. Under NI 43-101, estimates of inferred

mineral resources may not form the basis of feasibility or pre-feasibility studies or economic studies

except for a Preliminary Economic Assessment as defined under NI 43-101. Readers are cautioned

not to assume that further work on the stated resources will lead to mineral reserves on Winsome's

Adina property that can be mined economically. An inferred mineral resource has a lower level of

confidence than that applying to an indicated mineral resource and must not be converted to a

mineral reserve.
