CMC METALS RELEASES ADDITIONAL HIGH GRADE CRD-STYLE SILVER-LEAD-ZINC SAMPLES, A PROPOSED DRILL PLAN AND EXPANDS ITS AMY PROPERTY, NORTH- CENTRAL BRITISH COLUMBIA

CMC Metals Ltd. has identified additional high-grade CRD-style silver-lead-zinc samples from trenches and a historic adit dump on its Amy property in north-central British Columbia.

Samples were collected from the 4200 level adit dump and surrounding area with grades up to 643 grams per tonne silver, 18.76 per cent lead, 8.3 per cent zinc and 9.7 per cent manganese. Over all in three separate sampling and reconnaissance mapping efforts, 23 samples from a combination of outcrops, trench and dump samples have graded an impressive 977.5 g/t silver, 8.99 per cent lead and 4.7 per cent zinc which suggests that the area is characteristic of a very high-grade and large CRD system with potential multiple stacked mantos.

Mapping efforts have also shown that the vein/manto systems have projected good extents of up to 1.7 kilometres in strike length and an overall projected vein strike lengths on surface to date of over 2.6 kilometres in total.

The company now plans to initiate permitting for a drill program in 2025. The initial drill program designed estimates a requirement for over 10,000 metres of drilling to conduct a first-pass of the projected vein systems. The company intends to initially focus on the Amy prospect where drilling and portal construction identified impressive widths of mineralization. Company geologists have not been able to verify the historical results due to the drill core not having been properly recorded and stored and the adits deemed impassable for safety reasons and therefore should not be relied upon in any manner.

In addition, the company has 100 per cent acquired from Steven Scott, prospector, B.C. tenure 1109654, for 350,000 common shares subject to a 120-day-plus-one-day hold period. The deal is subject to Toronto Stock Exchange approval. Tenure 1109654 is 64.86 hectares in size and immediately adjoins the existing 100-per-cent-company-owned Amy tenures in the north-central portion of the property. The property now comprises a total of 954.4 hectares.

Kevin Brewer, president and chief executive officer, noted: "By taking the Amy project to a drill ready stage over the past three years we have delivered our promise to our shareholders. We are consistently delivering on our projects and we are about to deliver our new corporate strategy for our remaining projects now that we have optioned the Silverknife property to Coeur in a significant deal. I am very thankful to our hard working team and contractors who continue to enable us to implement our plans and provide highly promising prospects within the Rancheria silver district."

The Amy property is located within the emerging Rancheria silver district which is known to host numerous silver-lead-zinc occurrences and also includes the Silvertip mine (one of the world's highest grade underground silver-lead-zinc mines) owned by Coeur Mining. Amy is located only eight kilometres west of the Silvertip mine. It was actively explored in the early 1960s and 1970s but since that time has never been explored using modern exploration techniques. In 2021 CMC Metals also contracted SRK Consulting to compile all of the historic data from these early exploration efforts which will be utilized extensively in the planning and implementation of the 2025 and beyond drill programs at Amy.
