Comet Lithium Expands Royalty Exposure Through Strategic Véronneau Transaction

Comet Lithium Corp. (TSXV: CLIC) (FSE: 8QY) ("Comet" or the "Corporation") is pleased to announce that pursuant to an asset purchase agreement dated March 31, 2026 (the "Agreement"), it has completed the sale of its minority interest in the Véronneau property (the "Property") to Cunico Metals Inc. (the "Purchaser"), a private exploration-stage issuer for consideration consisting of common shares of the Purchaser and a retained royalty on the Property.

Transaction Highlights

As consideration for the transaction, Comet received:

• 1,000,000 common shares of the Purchaser at a deemed price of $0.10 per share; and
• a 0.5% net smelter return royalty ("NSR") on the portion of the Property corresponding to Comet's retained royalty area, as illustrated in Figure 1

The NSR royalty will apply to all mineral production from the Property.

Véronneau Property Overview

The Véronneau Property represents a compelling, road-accessible critical-minerals exploration opportunity in Québec's Eeyou Istchee James Bay region. The Property comprises approximately 20,764 hectares in a well-established Canadian mining jurisdiction, with access to regional infrastructure and an established mineral tenure and regulatory framework.

Located approximately 145 km north of Matagami, approximately 40 km north of Q2 Metals Corp.'s Cisco lithium property, and contiguous with Pivotal Metals' Horden Lake copper-nickel-PGM-cobalt project, Véronneau provides exposure to an active and increasingly prominent critical-minerals corridor. The Property is considered prospective for copper, nickel, platinum group metals and lithium based on its regional geological setting, historical exploration work and proximity to known mineralized systems.

The Purchaser intends to advance disciplined, modern exploration activities on the Property with the objective of evaluating and prioritizing high-potential targets across the land package. Comet believes the Purchaser is well positioned to advance the next stage of exploration at Véronneau and to evaluate the Property's mineral potential, while allowing Comet to retain exposure to future upside through its continuing economic interest in the Property.

Strategic Rationale

The transaction reflects Comet's evolving strategy of unlocking value from non-core assets while preserving meaningful long-term exposure to exploration and development upside.

Through its equity position in the Purchaser and retained 0.5% NSR royalty on Véronneau, Comet continues to build its emerging royalty portfolio. Combined with the Company's previously retained royalty interests on Puma Gold's Mackenzie project in New Brunswick, this transaction further expands Comet's portfolio of royalty exposure and reinforces a strategy of creating long-term, non-dilutive participation in the advancement of mineral assets beyond its core caesium and lithium exploration portfolio.

As Comet continues to prioritize its flagship lithium assets in Québec, the Company is also positioning itself to benefit from future third-party success through a growing pipeline of royalties designed to enhance optionality and long-term shareholder exposure to discovery, development and potential future production.
