Canadian Critical Minerals Drills 106 Metres of 0.539% CuEq Within 248 Metres of 0.438% CuEq at Thierry Mine Project

Calgary, September 20, 2023 - Canadian Critical Minerals Inc. (TSXV: CCMI) (OTCQB: RIINF) ("Canadian Critical Minerals" or the "Company") is pleased to announce assay results from the first two drill holes of a seven hole 2,600 metre exploration program that was completed at the Thierry Mine Project near Pickle Lake, Ontario in July 2023. Assay results for the remaining five holes are pending.

Early Highlights of the July 2023 Program are as follows:

• CCM-23-51 intersected 106 metres of 0.539% Copper Equivalent ("CuEq") mineralization (including 23.2 metres of 0.875 % CuEq mineralization) within continuous sulphide mineralization which started at surface and extended 248 metres down the hole, grading 0.438% CuEq.
• CCM-23-52 intersected 31.2 metres of 0.677% CuEq mineralization and 22.8 metres of 0.670% CuEq mineralization within continuous sulphide mineralization which started at surface and continued for 243.9 metres down the hole, grading at 0.382% CuEq.

Each hole intersected continuous zones of sulphide mineralization from surface and continued for more than 240m down the hole. The holes were drilled at 45 degrees dip to intersect mineralized lenses dipping at 50 degrees to the north, thereby representing intercepts of approximate true width. Assay highlights appear below.

Assay Highlight Table

*Copper Equivalent (CuEq) for drill intersections is calculated based on US$ 3.75/lb Cu, US$ 9.25/lb Ni, US$ 1,190/oz Pd and US$ 910/oz Pt with 100% metallurgical recoveries for all metals. Assays have not been capped. The formula used for the calculation is: CuEq = Cu % + (Ni grade X Ni Price)/(Cu Price) + ((Pd grade) X (Pd price / 31)) / (Cu price X 22) + ((Pt grade) X (Pt price/31)) / (Cu price X 22).

The 2023 summer program was designed to 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).

Ian Berzins, President and CEO commented, "We are pleased to see positive assay results from our initial drilling program at the Thierry Mine project with specific focus on the K1-1 deposit. We believe there is significant potential to expand upon the current Inferred Resource at K1-1."

Samples reported on in this press release were selected in the field, bagged, tagged, and sent to the facilities of ALS Laboratories in Thunder Bay, Ontario via bonded courier where they were processed using ME-MS41 Ultra Trace Aqua Regia for multi-element analysis and PGM-ICP23 for 30g Fire Assay for Pt, Pd and Au.
