CMC Metals Identifies High Grade Polymetallic Samples at its Proposed Future Targets at Silver Hart, Yukon

CMC Metals Ltd. (TSXV:CMB)(Frankfurt:ZM5N)(OTC PINK:CMCZF); (the "Company") is pleased to announce that recent exploration at its flagship Silver Hart property has identified high grade polymetallic samples within the calcareous units at its proposed future exploration targets

The Company has completed detailed mapping and sampling on it targets at Silver Hart identified from the SkyTEM airborne geophysical survey completed earlier this year. This work has successfully confirmed the merit of these targets for future drilling and the potential of the calcareous units to host high grade silver and zinc with assays returning up to 1,243 g/t silver, 20.06% lead and 28% zinc. The values are obtained in limestone and skarns that are in close contact with the granodiorite and extend for over 4.0 kilometers southeastwards onto the Blue Heaven property that the Company optioned from Strategic Metals.

Key highlights of the sampling effort are as follows (also refer to Figures 1 and 2):

The calcareous units at Silver Hart containing elevated silver, zinc and lead, appear to be present directly along strike with those on the Blue Heaven property where northeast mineralizing high grade polymetallic veins are also present. Drill pad building in 2021, in anticipation of future drilling, served to expose mineralization within the target areas identified from the SkyTEM survey where the calcareous units is in close contact with the Cassiar Batholith.

Mr. John Bossio, Chairperson noted, "The significant potential for high grade polymetallic deposits is being identified on our Silver Hart and Blue Heaven properties. This recent round of sampling is significant as it is demonstrating the potential of the calcareous units to host high grade mineralization outside of the high-grade vein system in the Main Zone that has been the sole focus of exploration to date. The highly positive results from our systematic exploration efforts are continuing to confirm our geological model for and in particular the importance of examining the contact relationship between the Cassiar batholith granodiorite and the overlying carbonates. We also see this important relationship throughout the Rancheria Silver District at our other properties such as Silverknife. Amy and Rancheria South. Our work at Silver Hart will help us understand the mineralizing systems throughout the district."

Mr. Kevin Brewer, President and CEO noted, "The polymetallic nature of mineralization on our properties is becoming more evident and we see this as a very positive development for future exploration. We are very excited about the potential of targets such as T1, T3, T4 and T5 and we are now planning efforts to further evaluate these areas through trenching and drilling in 2022 and beyond. The polymetallic high-grade nature of mineralization is especially important to the possible future viability of Silver Hart and our other properties in the Rancheria Silver district. The polymetallic nature of the mineralization is consistent with that of the Silvertip mine. Also, the Company considers that the content of minerals such as zinc, lead and copper will be increasingly important in the future as we are possibly entering a bull market in these commodities. According to date from kitco.com and Business Insider (see Figure 3), from October 2020 to current zinc prices have increased by approximately 57%, lead 36.7%, and copper 57.9%. We have seen a slight downturn in silver prices (-4%) but we are very positive in the outlook for silver prices in the foreseeable future. Silver Hart is clearly a polymetallic target where minerals such as zinc, lead and possibly copper are important contributors to the economic viability of the project. These recent results further serve to demonstrate the importance of being cognizant of the polymetallic nature of mineralization within the Rancheria Silver District. They also signal the potential for widespread mineralization at the Silver Hart Project."
