Calgary, Alberta--(Newsfile Corp. - June 3, 2026) - Canadian Critical Minerals Inc. (TSXV: CCMI) (OTCQB: RIINF) ("CCMI" or the "Company") is pleased to announce that the Chief Gold Commissioner of the Ministry of Mining and Critical Minerals for British Columbia has approved term renewals for an additional thirty (30) years for two mining leases at the Bull River Mine near Cranbrook, British Columbia.

CCMI applied to renew Mining Leases 212492 and 212493 at the Bull River Mine as per section 42(5) of the Mineral Tenure Act. The mining leases are located within the consultation area of the Ktunaxa Nation Council (KNC) and Shuswap Band (SB). Further to consultation with First Nations, the Province determined that the issue of term renewals will not significantly impact Aboriginal rights and interests. Mining Leases 212492 and 212493 have been renewed for thirty (30) years from November 23, 2022 to November 23, 2052 and from February 21, 2023 to February 21, 2053 respectively.

The renewals are significant for several reasons. The Company holds a Mining Permit M33 which lies within the lease boundaries. The Company intends to advance the Bull River Mine project in a phased approach wherein the Company plans to initially process approximately 155,000 tonnes of mineralized copper, gold and silver material from surface stockpiles at the project followed by a resumption of underground mining. The current mine plan for underground mining envisions an initial 10 year mine based on the current mineral resource. The Bull River Mine has been developed to a vertical depth of 350 metres and is currently maintained in a dewatered condition. The orebodies remain open at depth. The renewals ensure that the Company has sufficient runway to continue developing the Bull River Mine beyond the current mine plan.

The Company continues to work with consultants to complete an updated Project Description and Information Requirements Table (IRT) that are planned for submission to the First Nations and Major Mines Permitting Office of the Ministry of Mining and Critical Minerals within the next 60 days to support an update to Mining Permit M33 and a restart of the Bull River Mine.
