Canadian Critical Minerals Announces Increases of Indicated Metal of 11% for Copper and 17% for Gold at the Bull River Mine
Rhea-AI Summary
Canadian Critical Minerals (CCMI) has announced significant increases in mineral resources at its Bull River Mine near Cranbrook, B.C. The updated Mineral Resource Estimate shows an 11% increase in copper metal and a 17% increase in gold metal content compared to the 2021 estimate.
The total Indicated Mineral Resource now stands at 2.9Mt grading 1.58% Cu, 0.389 g/t Au, and 13.3 g/t Ag. The surface stockpile contains 173,263 tonnes of mineralized material grading 1.092% copper, 0.232 g/t gold, and 9.1 g/t silver, representing 4,172,800 lbs of copper, 1,292 ounces of gold, and 50,507 ounces of silver.
The Bull River Mine features a fully developed infrastructure with 21,000 metres of underground developments across seven levels, a 700 tonne per day conventional mill, crushing facilities, and grid power connection.

Calgary, Alberta--(Newsfile Corp. - March 4, 2025) - Canadian Critical Minerals Inc. (TSXV: CCMI) (OTCQB: RIINF) ("CCMI" or the "Company") is pleased to announce a
Highlights:
- Total Indicated Mineral Resource of 2.9Mt grading
1.58% Cu, 0.389 g/t, and 13.3 g/t Ag. - Total Inferred Mineral Resource of 1.6Mt grading
1.43% Cu, 0.388 g/t Au, and 12.1 g/t Ag. - Inclusion of stockpile and increase in metal prices have resulted in the Indicated Resource to increase by
11% in the Cu metal and17% in the gold metal content compared to the previous, 2021 MRE.
The current surface Mineral Resource has an effective date of December 31, 2024. The surface stockpile Mineral Resource is not based on a Cutoff grade ("COG") because the material is already on surface and the entire stockpile is reported. As of December 31, 2024, the Company had trucked 6,737 tonnes of pre-concentrated high-grade mineralized material to New Afton under an Ore Purchase Agreement ("OPA"). Under the OPA, New Afton performed assay services on all trucked material as well as low grade mineralized material that was rejected from the ore sorting process. The December 31, 2024 stockpile resource is estimated at 173,263 tonnes of mineralized material grading
Ian Berzins, President and CEO commented, "We are extremely pleased with the results of the up-dated Mineral Resource including underground and surface mineralized material. During the period November 2023 to August 2024, the Company crushed and screened 180,000 tonnes of mineralized run of mine material already on surface in a stockpile. Subsequently, the Company sorted coarse material through an ore sorter and both the high-grade material that was sent to New Afton plus the lower grade material that was rejected by the sorter and not trucked to New Afton were assayed for copper, gold and silver. As a result, 5,177,900 lbs of CuEq mineralized material were added to the current Mineral Resource at Bull River."

Mineral Resource Notes:
- The qualified person responsible for the mineral resource estimate is Sue Bird P.Eng of MMTS.
- The base case cut-off is
0.70% CuEq which more than covers the Processing costs of CDN$30 /tonne and Underground Mining costs of CDN$35 /tonne. - A minimum mining width of 2.0m is assumed.
- Mineral resources are based on a US
$2,200 /oz gold price, US$4.15 /lb copper price and US$26.5 /oz silver price and the following smelter terms:96.25% payable Cu,97.5% payable Au and95% payable Ag. - Forex of 0.72 US$:CDN$
- Treatment charges of US
$5 /tonne for Cu, Refining charges of US$0.005 /lb Cu, US$8 /oz for Au, US$0.5 /oz Ag. - Transportation charges of US
$100 /tonne Cu concentrate. - Metallurgical recoveries have been estimated as
93% for Cu,75% for Au, and90% for Ag. - The mineral resource has been confined by a "reasonable prospects of eventual economic extraction" underground shape equating to an NSR cut-off of CDN
$65 /tonne with all material within this shape reported as the resource. - The bulk density has been assigned values of 2.7 and 3.06 tonnes/m3 depending on mineralized domain.
- Rounding as required by reporting guidelines may result in summation differences.

The Bull River Mine is fully developed and dewatered with 21,000 metres of underground developments in terms of ramps, raises and drifting on mineralized structures on seven levels to a depth of 350 metres below surface. The surface infrastructure includes a 700 tonne per day conventional mill with adjoining crushing facilities as well as offices and mine maintenance facilities. The property is connected to grid power and there is year-round access to the site by paved and all-weather roads.
