CMC Announces New Mineral Resource Estimate for the Silver Hart Project

VANCOUVER, British Columbia, Nov. 27, 2024 (GLOBE NEWSWIRE) -- CMC Metals Ltd. (TSX-V: CMB) (Frankfurt: ZM5P) (“CMC” or the “Company”) is pleased to announce a new Mineral Resource Estimate (“MRE”) for its silver-lead-zinc Silver Hart Project (SHP), in Yukon, Canada.

The new MRE totals an Inferred resource of 8.820 Moz @ 145.2 g/t silver equivalent (“AgEq”) in 1,889,000 tonnes utilizing a cut-off grade of 50 g/t AgEq (See table 1). This MRE has been prepared in accordance with the Canadian Securities Administrators’ National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

Notes:

1. The effective date of this mineral resource statement is December 31, 2023.
2. The qualified person responsible for this Mineral Resource Estimate (MRE) is Charley Murahwi, M.Sc., P.Geo., FAusIMM.
3. The mineral resources have been estimated in accordance with the CIM Best Practice Guidelines (2019) and the CIM Definition Standards (2014)
4. Ordinary Kriging (OK) interpolation was used with a single block size of 5m x 5m x 5m.
5. The mineral resource results are presented in-situ within the optimized pit. Mineralized material outside the pit has not been considered as a part of the current MRE.
6. The tonnes and metal contents are rounded to reflect that the numbers are an estimate and any discrepancies in the totals are due to the rounding effects.
7. AgEq g/t = [(Ag ppm x %Recovery x Price/g) + (Pb ppm x %Recovery x Price/g) + (Zn ppm x %Recovery x Price/g)]/ (Ag Price/g x %Recovery).
8. Mineral resources unlike mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

A summary of the SHP mineral resource economic and technical parameters and/or assumptions is presented in Table 2 below.

Further details on the new mineral resource estimate at Silver Hart and the use of the above-mentioned parameters will be provided in the upcoming NI 43-101 report by MICON International Limited who undertook the MRE estimate on behalf of the Company.

Kevin Brewer, President and CEO of the Company noted, “We have a conceptual development plan that suits the size and grade of the resource estimate and the nature of the mineralization that starts at surface. The mineralization at Silver hart comprises of high-grade veins and mantos that are potentially amenable to open pit mining. Our plan is to fully evaluate developing these resources for a seasonal, small scale open pit operation developing each of the known mineralized areas. We plan to evaluate the potential ways to minimize project risk that will include the possible utilization of an ore sorter to enhance ore grades with the concentrate material then trucked to a processing facility. The closest potential mill may be at the Silvertip project owned by Coeur Mining, which would entail a trucking distance of approximately 100 kilometers from Silver Hart. CMC also hopes to establish a partnership arrangement with local First Nations to undertake this project and will be commencing discussions in the very near future. Our next steps are to engage discussions with First Nations and conduct the first round or metallurgical testing and ore sorting capabilities which we hope to commence in the near future, subject to financing.”

The new MRE also notes that there are opportunities to expand many of the known mineralized zones (TM, KL, K, S and M) and does not include any discussions on the potential for additional zones in the adjacent Blue Heaven Property that is 80% owned by CMC.

The Rancheria Silver District is located approximately 300 kilometers east of Whitehorse, Yukon in a 130 km long by 50 km wide belt that straddles the Yukon and British Columbia border. CMC has been actively exploring this silver district on the northern end at its Silver Hart and Blue Heaven properties and recently acquired a 100% interest in the Amy property and has optioned its Silverknife Project to Coeur Mining Inc.
