CMC METALS LTD. ANNOUNCES RECEIPT OF THE EXPLORATION PERMIT FOR THE SILVERKNIFE PROPERTY, NORTH-CENTRAL BRITISH COLUMBIA

CMC Metals Ltd. has received the exploration permit for the Silverknife property in north-central British Columbia.

The permit will allow the company to proceed with its planned 3,000-metre drill program that is targeting high-grade silver-lead-zinc carbonate replacement deposits (CRDs). The company is targeting an area in the northernmost portion of the property that has coincident gravity and electromagnetic anomalies. The project area is in close proximity to Coeur Mining Inc.'s Silvertip mine, one of the highest-grade underground silver-lead-zinc CRD deposits in the world, in an area that has been deemed to have high potential to host additional CRD deposits.

John Bossio, chairman, noted: "Securing this permit is a key milestone as we are especially excited about the potential of Silverknife in the Rancheria silver district. We have been looking at this project for a couple of years and it is a very exciting prospect."

Kevin Brewer, president and chief executive officer, noted: "Our team worked hard to secure this permit in time to commence our operations on schedule. We are currently mobilizing crews and establishing a new industrial camp to support exploration efforts. I wish to personally thank the efforts of the Tahltan central government, other stakeholders, the permitting team in the Smithers office of the B.C. Ministry of Energy and Mines, and Mr. Nelson Deborgorski, who were all great to work with on this permitting effort. I look forward to advancing this new project, which we feel has great potential to result in a significant discovery."
