COMET LITHIUM CONGRATULATES WINSOME RESOURCES ON ITS MAIDEN MINERAL RESOURCE ESTIMATE AT ADINA

Comet Lithium Corp. congratulates Winsome Resources Ltd. on the maiden mineral resource estimate (MRE) at its wholly owned Adina property, located in the Eeyou Istchee James Bay region of Quebec and directly adjacent to Comet Lithium's 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 per cent lithium oxide (Li2O) of inferred resources, at a cut-off grade of 0.6 per cent Li2O, for a total of 1.62 million tonnes contained lithium carbonate equivalent (1). The MRE is based on 27,600 metres of drilling at an approximate spacing of 100 metres by 100 metres. As reported by Winsome, it has five drill rigs now operating at Adina with over 25,000 metres of additional infill and extensional drilling awaiting assay, and targeting an MRE upgrade in first half 2024. Winsome further confirms being well financed to undertake over 50,000 metres of infill and step-out drilling in 2024 at Adina. Additionally, as reported by Winsome, the resource and geological modelling have 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 mineralization defined by systematic drilling to 1,340 metres as well as confirming the continuity of mineralization 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 approximately 660 metres away from the property boundary. Additionally, Winsome has identified pegmatite targets located less than 50 metres 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 (2), Azimut's Galinee (3) and Loyal Lithium's Trieste (4) discoveries, underpins the significant potential of the Trieste formation," commented 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."

About Comet Lithium Corp.

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-per-cent-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 (Joint Ore Reserves Committee) code, 2012 edition. The JORC code has been accepted for current disclosure rules in Canada under National Instrument 43-101. The meaning of mineral resources under the JORC code differs from that of the CIM (Canadian Institute of Mining, Metallurgy and Petroleum) definition standards. There are no technical reports 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 Dec. 11, 2023, and such information has not been verified by the corporation's qualified person but is believed to be reasonably reliable. 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 the Liberty property is on strike with Andina's mineralized pegmatites in addition that Winsome has identified pegmatite targets located less than 50 metres 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 Dec. 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 prefeasibility 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.

We seek Safe Harbor.
