CMC Metals Ltd. (TSXV: CMB) (Frankfurt:ZM5P) (CMCXF: OTCQB) ('CMC' or the 'Company') announces positive results from its drill program conducted at its flagship Silver Hart Project in the 2022 exploration season.

Approximately 4,404 meters of diamond drilling was completed in 25 holes. Highlights include; Hole SHM22_06 intersected 813 g/t AgEq over 8.25 meters (at a depth of 23.15 - 31.40 meters), including a 0.60 meter intersection of 2,827 g/t silver, 18.7% zinc, and 1.6% lead.

The drill program tested five areas of the property including; (i) An extension of the KL vein - Main Zone; (ii) An area of the carbonate belt proximal to the Main Zone veins; (iii) The St. Patrick Vein; (iv) T1 Conductor and (v) The T4 Conductor.

A summary of the results from this drilling is provided as follows: (i)	Extension of the KL Vein: Three holes (M22_04, SHM22_16 and SHM22_02) for a total of 457.46 meters which were completed to test the extension of the KL vein system. M22_04 encountered visible chalcopyrite mineralization which prompted the addition of hole SHM22_16 to investigate the possible extent of copper mineralization. M22_04 intersected 10% zinc over 1.10 meters from a hole depth of 38.40 to 39.50 meters. SHM 22_16 also intersected 62 g/t silver and 7.1% zinc over 0.50 meters from a hole depth of 66.15 to 66.65 meters. These intersections are thought to represent a possible north-easterly extension of the KL zone for approximately 200 meters. SHM22_02 further corroborated a possible north-eastern extension as it was drilled between the KL zone and hole M22_04. SHM22_02 intersected 175 g/t silver, 5.4% zinc, and 0.2% lead (342 g/t AgEq) over 1.10 meters from a hole depth of 53.70 to 54.80 meters and other mineralization encountered at various depths. The north-easterly extension of the KL zone requires further drill testing between these new holes and previous holes to verify the continuity of the zone.

Carbonate Belt: Fifteen holes were conducted to test areas of oxidized mantle and mineralization on surface and/or identified from trenching. A majority of these holes were drilled oblique to the Main Zone veins but perpendicular to the bedding of interlayered skarnified and limestone units in an area covering 500 meters by 900 meters (see Plate 1). Oxidized areas are thought to be associated with fractures and possible epithermal alteration. Further testing of visible mantos around the M Zone with holes SHM22_06 and SHM22_15 provided some impressive results. Hole SHM22_06 intersected 813 g/t AgEq over 8.25 meters (at a depth of 23.15 - 31.40 meters) including a 0.60 meter intersection of 2,827 g/t silver, 18.7% zinc, and 1.6% lead at a hole depth intercept of 25.60 - 26.20 meters, and another significant 0.60 meter intersection of 205 g/t silver, 6.1% zinc, and 7.5 % lead at a depth of 27.60 - 28.20 meters. SHM22_15 intersected a 5.95 meter section (at a depth 49.00 - 54.95 meters) grading 232 g/t AgEq including a 0.90 meter intersection (at a depth of 50.60 - 51.50 meters) grading 80 g/t silver, 17.5% zinc, and 0.4% lead.
