Positive Gravity Survey Results Strengthen Targets at the Silverknife Property, Northern British Columbia

VANCOUVER, BC / ACCESSWIRE / August 10, 2022 / CMC Metals Ltd. (TSXV:CMB) (Frankfurt:ZM5P) (OTC PINK:CMCXF) ("CMC" or the "Company") is pleased to announce encouraging results from the gravity survey on our Silverknife Property in northern British Columbia. The gravity survey was recently completed by McKeown Exploration Services ("MES"), a specialist in gravity surveys, and results interpreted by Dr. Chris Hale and Mr. John Gilliatt of Intelligent Exploration ("IE") who are the Company's geophysical consultants.

Approximately 15.4 line-kilometers of gravity survey were completed in the northern part of the Property to evaluate significant conductors (see Figure 1) identified by the airborne SkyTEM survey (see CMC Press Release of July 13, 2022). A gravity anomaly coincides with the northern conductivity target (Figure 2) and a second, stronger gravity anomaly is centred about 300m farther south (see Figures 2 and 3). Both of these targets are covered by quaternary alluvium so their geophysical anomalies are new discoveries. The survey also identified a local increase in gravity in the vicinity of the historical drilling. IE noted that the deep anomaly in the northern portion of the Silverknife Property is a good drill target and that the coincidence between the gravity and conductivity anomalies north of the Tootsee River is remarkable.

The eastern boundary of the Silverknife Property is approximately 1.1 kilometers from the Silvertip Mine owned by Coeur Mining Inc. ("Couer"). Silvertip is one of the highest-grade underground silver-lead-zinc CRD style mines in the world and is located within the emerging highly prospective Rancheria Silver District that extends from northern British Columbia into south-central Yukon. CMC is actively exploring the Rancheria Silver District for CRD, skarn, and high-grade silver-lead-zinc vein style deposits on its five properties including the flagship Silver Hart Property and Blue Heaven claims in Yukon, and Silverknife, Amy and Rancheria South which are all in close proximity to the SilverTip mine in northern British Columbia.
