CMC Metals Ltd. Announces Start of Drilling and Extensions of the Main Zone at Silver Hart

The first 3 holes of the 2021 drill campaign have been planned to target a 150-meter extension of the TM area within the Main Zone which has currently been defined along a 250-meter strike length. This area was previously drilled by Silver Hart Mines Ltd. in the mid 1980's but due to lack of records and certified assays, this part of the zone could not be included in the recent resource estimation.

Drilling will then target an extension of the Main Zone to the northwest currently referred to as "T5". This significant possible extension of the Main Zone is associated with a geophysical anomaly in excess of 600 meters in strike length. The dominant mineralizing structure through the Main Zone trends directly towards T5. In addition, recent prospecting and trenching in the T5 area has also identified mineralization at surface in this area. This possible extension could add up to an additional 50% of strike length to the known mineralized Main Zone.

A total of 8 areas of exploration interest have been identified on the property by means of the 2020 IP survey and the 2021 SkyTEM survey. Targets T2 and T3 were generated from the IP survey and correspond to zones of relatively low resistivity and high chargeability. T5 occurs at the boundary of the IP survey and demonstrates very low resistivity and very high chargeability and is by far the strongest conductor on the property as revealed by the SkyTEM survey.

The remainder of the targets identified by the SkyTEM survey correspond to known, or presumed, sedimentary units which are in close proximity to the intrusive heat source. Also encouraging is the fact that these anomalies trend northeast which is the dominant mineralizing structure of the Rancheria Silver District and suggests that feeder structures into the schists and limestones may be present. All targets will be mapped and prospected during the 2021 season, some will be evaluated by means of soil geochemical survey, and time and financing permitting, it is the hope of the Company to complete preliminary drill testing of most of these targets.

John Bossio, Chairman noted, "This is the most significant exploration program ever completed by CMC at Silver Hart to date. We are excited about the potential to increase known resources in the Main Zone along strike and at depth and test most of these new targets. We are optimistic this will add resources at Silver Hart."

Kevin Brewer, President and CEO noted, "Our airborne geophysics program was very successful in identifying targets in our known mineralized areas, confirming targets in new areas that we had delineated in our 2020 exploration efforts, and to provide us with new targets where no previous work has been conducted. Phase 1 of our drill program will provide us with considerable insight into the overall potential to expand resources at Silver Hart. An examination of past assays has also identified the potential for copper and gold to be included as elements within future resource estimates although this requires additional study. Our assaying this year will be documenting the content of these elements to see if they can positively contribute to the project."
