CANADIAN CRITICAL MINERALS FOCUSES ON BULL RIVER MINE PROJECT

Canadian Critical Minerals Inc. is focused on its flagship Bull River mine (BRM) project near Cranbrook, B.C. The BRM is the highest-grade advanced underground copper mine in British Columbia. The mine is fully developed with over 22 kilometres of underground ramps, tunnels and raises for approximately 75 per cent of the current mineral resource. The mine has been maintained in a dewatered condition since 2010. The project has significant infrastructure in place, including roads, grid power, rail and proximity to established mining communities, including Cranbrook, Fernie and Kimberley.

The attached resource estimate table summarizes the current indicated and inferred resource estimate for the project at the base-case copper equivalent (CuEq) grade of 0.9 per cent CuEq (see the press release on SEDAR+ dated Feb. 23, 2021). The average thickness of both the indicated and inferred resource is 5.5 metres.

Mineralized zones at BRM are composed of vertical to subvertical sulphide-bearing quartz carbonate veins. Mineralization consists primarily of pyrite, pyrrhotite and chalcopyrite with minor local galena, sphalerite, arsenopyrite and cobaltite. The BRM deposit has been described as a Churchill-type vein copper-silver deposit. These deposits are typically low tonnage (fewer than 1.0 million tonnes) and high grade (1 per cent Cu to 4 per cent Cu), and can extend hundreds of metres along strike and downdip. Its current resource at BRM is larger than a typical Churchill type deposit, grades are improving at depth and the mine is still relatively shallow.

To date, the BRM has been developed to a depth of 350 metres from surface, and mineralized structures have been identified up to 175 metres below the lowest workings of the mine. In the first half of 2021, six diamond drill holes were drilled from underground workings on the nine level. All holes intersected mineralized structures between 425 metres and 525 metres below the surface portal and between 75 metres and 175 metres below the lowest workings of the mine on the nine level. The intersections do not represent true width of the vein structures (see the press release on SEDAR+ dated Sept. 30, 2021).

The purpose of the 2021 drilling program was to test the downdip extension of the vein systems under the current workings to demonstrate the potential that the current resource can be extended on strike and to depth. Diamond drill hole BRU 21-05 was particularly encouraging, intersecting the highest gold values in the history of the property. All drill hole intersections met or exceeded the minimum width for mining.

Once the company begins receiving proceeds from the sale of a portion of the surface stockpile at the BRM, it will be better positioned to initiate a new drilling program targeting deeper mineralized structures at BRM.

Ian Berzins, president and chief executive officer, commented: "With the successful competition of our 2023 summer drilling program at the Thierry mine project, all of our leases and claims in Ontario are now in good standing, and we can concentrate on advancing our Bull River mine project. Priorities for BRM include implementation of the ore purchase agreement with New Afton, completion of our final permit application to restart the Bull River mine and deep drilling to further expand the known resource."

About Canadian Critical Minerals Inc.

Canadian Critical is a mining company primarily focused on two near-term copper production assets in Canada. Canadian Critical's main asset is the 100-per-cent-owned Bull River mine project (greater than 135 million pounds of copper) near Cranbrook, B.C., which has a mineral resource containing copper, gold and silver. Canadian Critical also owns a 39-per-cent interest in the Thierry mine project (greater than 1.3 billion pounds of copper) near Pickle Lake, Ont., which has a mineral resource containing copper, nickel, silver, palladium, platinum and gold.
