Canadian Critical Minerals Provides Up-Date on Thierry Drill Program

Calgary, Alberta--(Newsfile Corp. - July 18, 2023) - Canadian Critical Minerals Inc. (TSXV: CCMI) (OTCQB: RIINF) ("Canadian Critical Minerals" or the "Company") is pleased to provide an update on the exploration drilling program which began at the Thierry Mine Project near Pickle Lake, Ontario on July 6, 2023. To-date the Company has completed four NQ diamond drill holes and 1,229 metres of drilling with all holes encountering visual mineralization including copper, nickel and zinc. The Company cautions readers that visual identification of mineralization does not guarantee, or replace, assay results. Assay results may not meet or exceed results from earlier drill programs. Drill core samples have been selected for assay and the results will be reported once available.

The 2023 summer program is designed for approximately 2,500 metres of diamond drilling and will focus on expanding upon the K1-1 deposit which is a large tonnage, near surface deposit located approximately 3 km east of the past producing Thierry Mine. The K1-1 deposit has a current Inferred Mineral Resource within an optimized Whittle pit shell consisting of the following: 53,614,000 tonnes grading 0.38% Cu, 0.10% Ni, 1.8 g/t Ag, 0.03 g/t Au, 0.05 g/t Pt and 0.14 g/t Pd at a NSR of C$12/tonne (see NI 43-10 Technical Report filing on SEDAR dated February 22, 2021). The K1-1 deposit consists of approximately seven en echelon stacked lenses dipping at approximately 55 degrees to the north. The Company has outlined 40 drill targets intended to improve information on strike and down dip mineralized lens extensions relative to the pit shell. The 2023 program will focus initially on seven to eight priority targets. Based on planned drill angles, the majority of drill holes should intersect structures at approximate true width.

CCM-23-51 Complete

CCM-23-51 was collared approximately 60 metres south and 20 metres east of K-11-09 which was previously drilled by Cadillac Ventures in 2011. (See press release on SEDAR by Cadillac Ventures of August 9, 2011). K-11-09 yielded 105 metres at 0.35% Cu and 0.08% Ni beginning 36 metres from surface. CCM-23-51 was drilled parallel to K-11-09 and the hole was stopped after 275 metres where it entered barren mafic volcanics as expected. Mineralization is consistently present throughout the entire hole. Chalcopyrite (Cu) and pyrrhotite are the primary sulphides with traces of pentlandite (Ni) and sphalerite (Zn).

CCM-23-52 Complete

CCM-23-52 was collared approximately 80 metres north of K-11-10 which was previously drilled by Cadillac Ventures in 2011. (See press release on SEDAR by Cadillac Ventures of August 16, 2011). K-11-10 yielded 157 metres at 0.329% Cu and 0.064% Ni beginning 6 metres from surface. The hole was stopped after 275 metres where it entered barren mafic volcanics. Mineralization is consistently present throughout the entire hole. Chalcopyrite (Cu) and pyrrhotite are the primary sulphides with traces of pentlandite (Ni) and sphalerite (Zn).

CCM-23-53 Complete

CCM-23-53 was collared approximately 60 metres south of K-11-27 which was previously drilled by Cadillac Ventures in 2011. (See press release on SEDAR by Cadillac Ventures of January 25, 2012). K-11-27 yielded 178 metres at 0.35% Cu and 0.06% Ni beginning 127 metres from surface (including 37 metres at 0.65% Cu and 0.08% Ni and 0.25 g/t Pd). CCM-23-52 was drilled parallel to K-11-27 and the hole was stopped after 275 metres where it entered barren mafic volcanics. Mineralization is consistently present throughout the entire hole. Chalcopyrite (Cu) and pyrrhotite are the primary sulphides with traces of pentlandite (Ni) and sphalerite (Zn).

CCM-23-54 Complete

CCM-23-54 was collared approximately 160 metres north of K-11-01 which was previously drilled by Cadillac Ventures in 2011. (See press release on SEDAR by Cadillac Ventures of May 5, 2011). K-11-01 yielded 27 metres at 0.58% Cu beginning 160 metres from surface (including 9 metres at 0.92% Cu) and 53 metres at 0.27% Cu beginning 189 metres from surface. CCM-23-54 was drilled parallel to K-11-01 and outside the conceptual pit shell to test for down dip extensions of known mineralization. This hole is collared in barren mafic volcanics. Mineralization is consistently present, once through the volcanics at the top of the hole, from 189 to 349m. Chalcopyrite (Cu) and pyrrhotite are the primary sulphides with traces of pentlandite (Ni) and sphalerite (Zn).

Ian Berzins, President and CEO commented, "Our geological team, led by Brian Newton, is pleased with the visual observation of copper, nickel and zinc mineralization in all four holes of our 2023 drilling program at the Thierry Mine project that is focused on expanding the K1-1 deposit. All four holes have identified mineralized structures consistent with our current Resource model. We believe there is significant potential to expand upon the current Inferred Resource at K1-1."
