Canadian Critical Minerals Announces an Extension and Amendment of the Capacity Funding Agreement Regarding the Bull River Mine Project with Ktunaxa Nation Council

Calgary, Alberta--(Newsfile Corp. - September 28, 2026) - Canadian Critical Minerals Inc. (TSXV: CCMI) (OTCQB: RIINF) ("CCMI" or the "Company") is pleased to announce that the Capacity Funding Agreement (the "Agreement") with the Ktunaxa Nation Council (the "KNC"), including minor amendments to the Agreement regarding its Bull River Mine Project near Cranbrook, British Columbia, has been extended to December 31, 2027.

The Bull River Mine Project is located within ʔamakʔis Ktunaxa, the traditional territory of the Ktunaxa Nation (i.e. Ktunaxa homelands). In this agreement, the KNC represents the Ktunaxa Nation at the direction of the four Ktunaxa First Nation governments of ʔAkisq̓nuk First Nation, ʔaq̓am, yaqan nuʔkiy, and Yaq̓it ʔa·knuqⱡi'it First Nation. The Company entered into the original Capacity Funding Agreement with KNC on May 25, 2022.

The Agreement provides a framework for the purposes of information sharing and engagement and, where appropriate, accommodation between CCMI and Ktunaxa First Nations. Funds will be used for the purpose of defraying costs incurred by KNC in carrying out and completing the regulatory review of the Bull River Mine Project application in addition to other engagement activities between CCMI and KNC. Previously, the Company notified KNC and the British Columbia Major Mines Office on July 16, 2026 of its intent to begin processing existing mineralized stockpiled material on surface at the mine and then resume underground mining operations.

Ian Berzins, President and CEO commented, "We are extremely pleased to complete this extension of the Capacity Funding Agreement with KNC. It provides for a structured process of information sharing and engagement surrounding the Bull River Mine Project. We look forward to a long-term relationship with the Ktunaxa Nation."
