CMC Announces New Mineral Resource Estimate for the Silver Hart Project

Core Viewpoint - CMC Metals Ltd. has announced a new Mineral Resource Estimate (MRE) for its Silver Hart Project in Yukon, Canada, indicating significant silver-lead-zinc resources that could support future mining operations [1][2]. Mineral Resource Estimate - The new MRE totals an inferred resource of 8.820 million ounces (Moz) at an average grade of 145.2 grams per tonne (g/t) silver equivalent (AgEq) from 1,889,000 tonnes of material, using a cut-off grade of 50 g/t AgEq [2]. - The MRE is compliant with the Canadian Securities Administrators' National Instrument 43-101 standards [2]. Breakdown of Resources - The resource estimate includes various zones with differing grades and tonnages: - TM Zone: 269,000 tonnes at 229.8 g/t AgEq, totaling 1.985 Moz AgEq - S Zone: 127,000 tonnes at 334.5 g/t AgEq, totaling 1.368 Moz AgEq - KL Zone: 1,026,000 tonnes at 110.9 g/t AgEq, totaling 3.659 Moz AgEq - K Zone: 265,000 tonnes at 79.8 g/t AgEq, totaling 0.680 Moz AgEq - M Zone: 202,000 tonnes at 173.6 g/t AgEq, totaling 1.128 Moz AgEq [2]. Economic and Technical Parameters - Mining cost is estimated at CAD 10.00 per tonne for all material, processing cost at CAD 25.50 per tonne of crude feed, and general and administrative (G&A) cost at CAD 5.00 per tonne of crude feed [4]. - The exchange rate is set at CAD to USD 0.75, with silver priced at USD 23.30 per ounce, lead at USD 1,892 per metric tonne, and zinc at USD 2,505 per metric tonne [4][5]. - Metallurgical recovery for all metals is estimated at 80% [5]. Development Plans - The company has a conceptual development plan for a seasonal, small-scale open pit operation, focusing on high-grade veins and mantos that are amenable to open pit mining [6]. - Plans include evaluating the use of an ore sorter to enhance ore grades, with potential processing at a nearby mill approximately 100 kilometers away [6]. - The company aims to establish partnerships with local First Nations and will begin discussions soon [6]. Exploration and Property Details - CMC Metals is actively exploring the Rancheria Silver District, which spans approximately 130 kilometers long by 50 kilometers wide, and includes the Silver Hart and Blue Heaven properties [7]. - The company has recently acquired a 100% interest in the Amy property and has optioned its Silverknife Project to Coeur Mining Inc.
