Calgary, Alberta--(Newsfile Corp. - June 17, 2024) - Canadian Critical Minerals Inc. (TSXV: CCMI) (OTCQB: RIINF) ("CCMI" or the "Company") is pleased to report that revenues for the Company have continued to increase from the sale of stockpiled copper, gold and silver mineralized material at the Bull River Mine ("BRM") project near Cranbrook, BC. During the month of May 2024, the Company trucked 360 wet metric tonnes ("wmt") of mineralized material to New Afton and the Company received a provisional payment of approximately US$103,000 for the May 2024 shipments versus approximately US$72,000 for April 2024 shipments. The mineralized material sent to New Afton graded 3.86% Cu, 0.77 g/t Au and 31.7 g/t Ag.

The Company is using a Steinert KSS 100 X-Ray Transmissive Ore Sorter ("Ore Sorter") to pre-concentrate coarse mineralized material from a large surface stockpile at the BRM prior to transporting to New Afton for processing under an Ore Purchase Agreement ("OPA") (see press release dated October 5, 2023, on Sedar+). During May 2024, the Company operated the sorter on a Monday to Friday dayshift only basis. The Company lost approximately one week of operating time due to a tear in the conveyor belt feeding the ore sorter. The Company will be transitioning to a Monday to Sunday dayshift only operation beginning June 15, 2024, to better utilize the ore sorter and increase daily throughput.

Ian Berzins, President and CEO commented, "We are encouraged by the May 2024 results which represent the highest-grade product produced to-date at the BRM through pre-concentration of stockpiled material. The run of mine mineralized material from the surface stockpile grades 1.39% copper, 0.29 g/t gold and 11 g/t silver so we generated grade improvements of over 265% for all metals using the ore sorter during the month. The stockpile is not totally homogeneous in terms of grade, so we expect to see some fluctuation in results in coming months."
