Comet Lithium Announces $1.25 Million Cash Sale Of Ducran Property

Strategic Redeployment Of Capital Toward Pollux Property (Formerly Elmer East)

Rouyn-Noranda, Québec, Canada – February 18, 2026 – Comet Lithium Corporation (TSXV: CLIC; FSE: 8QY) (“Comet Lithium” or the “Corporation”) is pleased to announce that pursuant to an asset purchase agreement dated February 18, 2026 (the “Agreement”),  it has completed the sale of its Ducran property (the “Ducran Property”) to IAMGOLD Corporation (“IAMGOLD”) for total cash consideration of $1,250,000, payable at closing.

Ducran Property Overview

The Ducran Property is a strategically located polymetallic exploration asset situated in the Chapais–Chibougamau mining camp of Québec. At the time of sale, the Property comprised 49 registered mining claims covering approximately 2,700 hectares of prospective ground within a historically active polymetallic belt.

The Property has been the subject of past exploration work, including airborne geophysics (notably VTEM surveys) and limited drilling targeting sulphide-bearing conductors. This work outlined favourable geological settings prospective for multiple metals.

Transaction Details

Under the terms of the Agreement, IAMGOLD acquired 100% of Comet’s interest in the Ducran Property for a one-time cash payment of $1,250,000.

In connection with the closing of the transaction, Comet also completed an amendment and settlement with the original property vendor, which included:

• a cash payment of $120,000 to the original property vendor pursuant to the original property agreement;
• confirmation that the existing royalty remains in good standing; and
• the transfer of the royalty buyback rights to IAMGOLD, such that any future buyback is now attributable solely to IAMGOLD.

Following closing, Comet retains no ownership interest or ongoing obligations with respect to the Ducran Property.

Strategic Rationale and Use of Proceeds

“This transaction represents an excellent monetization of a non-core asset in our portfolio,” said Vincent Metcalfe, President and Chief Executive Officer of Comet Lithium Corp. “The proceeds from the sale provide non-dilutive capital that will be directed toward advancing our flagship discovery at Pollux, formerly known as Elmer East.”

Mr. Metcalfe added: “Pollux continues to deliver compelling exploration results, and we see significant upside potential as we advance the project. This monetization allows us to focus capital where we believe it will generate the strongest long-term value for shareholders.

About the Pollux Project (formerly Elmer East)

The Pollux Project is Comet Lithium’s priority discovery in the James Bay region of Québec and represents a rapidly evolving lithium–cesium–tantalum (LCT) pegmatite system. The project was renamed from Elmer East to Pollux to reflect the Corporation’s improved geological understanding of the system and the growing importance of cesium-bearing mineralization, including the identification of pollucite, the principal ore mineral of cesium.

Recent exploration work has confirmed the presence of highly evolved pegmatites, a key geological hallmark of fertile LCT systems capable of hosting lithium, cesium, and tantalum mineralization. The recognition of cesium mineralization at Pollux is considered significant, as cesium is a rare and strategically important critical mineral with limited global sources.

The name Pollux was selected as a deliberate reference to pollucite, the primary cesium mineral, and aligns with Comet Lithium’s corporate identity while underscoring the project’s emerging multi-commodity potential.
