CMC Announces the Identification of Six Significant Geophysical Targets on its Silverknife Property

VANCOUVER, BC / ACCESSWIRE / May 11, 2022 / CMC Metals Ltd. (TSXV:CMB)(Frankfurt:ZM5P)(OTC PINK:CMCXF) ("CMC" or the "Company") is pleased to announce significant targets have been identified on its Silverknife property as a result of a recent geophysical interpretation completed by Intelligent Exploration ("IE"). Dr. Chris Hale and Mr. John Gilliatt have recently completed an interpretation of geophysical data of the electromagnetic and magnetic airborne geophysical survey completed by SkyTEM Canada Inc. on the property in 2021. The silver-lead-zinc Silverknife Prospect is located within the emerging Rancheria Silver District that extends from south-central Yukon into Northern British Columbia and hosts the Silvertip Mine owned by Coeur Mining Inc. Silvertip is one of the highest-grade underground silver-lead-zinc mines in the world.

IE noted that the Total Magnetic Intensity ("TMI") on the Silverknife claims (See Figure 1) shows TMI highs indicating more magnetic intrusive rocks (Cassiar granodiorite) and broad areas of comparatively non-magnetic sedimentary rocks including limestones and dolomites that potentially could host a carbonate replacement (CRD) style deposit similar to the neighboring Silvertip Mine and CMC's Amy Prospect approximately 8km west of Silverknife. The TMI data also show that the intrusive is more extensive than previously recognized and its proximity to the McDame Formation and Tapioca Formation limestones offer good potential for them to host a CRD style deposit.

In total, six targets were identified at Silverknife (see attached figure 2). Three targets are located in the northwestern portion of the property and are newly discovered anomalies. These anomalies appear to follow the contact of the Cassiar Batholithic rocks with sedimentary sequences believed to be associated with the River Road and Tapioca Formations.

The remaining three targets in the south-central portion of the Property occur close to previously identified geochemical anomalies located on a downslope and appears to form at the contact of a magnetic and resistive body, possibly indicating skarn mineralization. The anomaly is considered to be at shallow depth and therefore mapping and possible trenching of these conductors has been recommended.

The Company is also noting that the prospectivity of the Silverknife Property has been elevated by recent news from Coeur Mining Inc. (Coeur Mining Press release, April 28, 2022) on their exploration of the Silvertip Mine Claims where a new zone called Camp Creek West was recently discovered. This zone is located west of the Camp Creek Fault and remains open to the west, north and south. It extends known mineralization toward the Silverknife claims.

Mr. John Bossio, Chairperson noted, "We are extremely excited about these new developments on our Silverknife Prospect and Coeur Mining's new Camp Creek West discovery. We are now working to accelerate exploration efforts on Silverknife this summer."

Mr. Kevin Brewer, President and CEO stated: "From historical exploration, we thought there was potential for additional targets in the northern portion of the Property, and it is exciting that this has now been verified by the SkyTEM survey. The additional targets in the south-central portion of the Property coincide with previously known geochemical targets. This strengthens our belief that CRD style targets like Silvertip, that typically form in clusters, may exist on our Silverknife claims. Plans are underway to undertake a gravity geophysical survey on the northern targets and a detailed mapping, prospecting and/or trenching program on the south-central targets."
