CMC Metals Ltd. Acquires the Silver-Gold Polymetallic Gavilanes Project in San Dimas District, Durango, Mexico

The silver-gold polymetallic Gavilanes Project (13,594.5 hectares) has a current NI 43-101 Inferred Resource of 18,174,000 contained silver-equivalent ("Ag-Eq") ounces at an average grade of 320.3 g/t Ag-Eq within 1,765,000 tonnes (Mine Development Associates/Respec Resource Gesociences Inc., 2021). The metal prices assumed in the resource estimate were $19.00 USD/oz silver, $1,600 USD/oz gold, $3.50 USD/lb copper, and $1.00 USD/lb for lead and zinc.

Gavilanes is a low to intermediate sulfidation epithermal deposit and is located in the Sierra Madre Occidental Province in southwestern Durango. Limited drilling at the site has been completed over 0.2 square kilometers of veins. Gavilanes has been subjected to periodic episodes of drilling totalling 61 diamond drill holes (13,011.25 meters). A majority of the drilling (47 holes) was completed by Santa Cruz Silver Mining. The drilling focused on the Guadalupe Solitude structure along only 500 meters. The San Nicolas mineralized structures, which span 2.6 kilometers, have only been tested over 250 meters with drilling intersecting an important gold system that was later confirmed with mapping and surface sampling.

Highlights of some previous intersections from historical drilling efforts include:

• SCSN-01: 8 meters 155 g/t silver
• SCSN-04: 17.8 meters of 465 g/t silver
• SCSN-05: 2.4 meters of 6.75 g/t gold
• SCGP-02: 4.25 meters of 233 g/t silver and 0.33 g/t gold
• SCGP-11: 4.8 meters of 616 g/t silver
• SCGP-12: 4 meters of 243 g/t silver
• SCGP-15: 3.4 meters of 298 g/t silver
• SCGP-22: 3.3 meters of 2,540 g/t silver
• SCGP-26: 8.6 meters of 409 g/t silver
• SCHN-12: 6.3 meters of 2,016 g/t silver and 0.16 g/t gold

(note: the results do not include other metals present such as lead, zinc, copper and/or gold which could result in higher silver equivalent grades)

Initial drilling will focus on further extensions of the San Nicolas vein, Descubridora, Veta Del Pueblo and Guadalupe-Soledad veins. Average veins encountered to date are approximately 3.0 meters in width and typical contain varying amounts of silver, gold, copper, lead and zinc.

Recent mapping efforts by Sailfish identified more than 20 veins covering an area in excess of 15 square kilometers some with strike lengths estimated in excess of 2.0 kilometers. Preliminary sampling of a majority of the veins has indicated that they are mineralized (see Map 2). Highlights of the surface sampling include:

• Sample 43038, Veta Del Pueblo: 1 meter grading 1,867 g/t silver
• Sample 43235, Descubridora Vein: 2 meters grading 24.4 g/t gold and 44.5 g/t silver
• Sample 45352, San Nicolas Vein: 1.5 meters grading 6.07 g/t gold and 201 g/t silver
• Sample 45331, San Nicolas Vein: 1.0 meter grading 30 g/t gold, 190 g/t silver

Key points arising from these results are:

• They demonstrate the potential for very large areas of prospectivity on the main vein structures outside of areas subjected to historical drilling;
• The potential for significant gold mineralization especially in the southeastern extensions of the veins which are exposures of the deeper parts of the veins; and,
• These sample results do not include other sample results on new veins identified and/or areas immediately outside of the core Gavilanes Zone;

It is also highly probable that the identified volume of mineralized veins will be increased by drilling the dip and strike extensions of the partly drill tested Gavilanes Zone, and early stage detailed mapping of the Central and Western Zones.

Thirty-seven of the Santa Cruz drill holes were used to derive the resource estimate. Sailfish subsequently logged and assayed the remaining ten holes not included in the current resource estimate. Therefore, after the initial round of drilling it is the Company's intent to incorporate these holes and new drilling results into a revised resource estimate in late Q4-2024/early Q1-2025. Gavilanes is located only 23 km northeast of the San Dimas/Tayoltita mine operated by First Majestic Silver Corp and shares many geological and mineralogical similarities with the mine deposit.

Descriptions of the property potential are included within various technical reports and recent studies which will be placed on the Company website (www.cmcmetals.ca).

Mr. Kevin Brewer, President and CEO of the Company noted: "Gavilanes is a transformational transaction. It is a major asset with immense exploration potential that provides the opportunity for significant growth of the Company in 2024 and beyond. To acquire a permitted project with a solid resource base, extensive mineralized veins in three mineralized zones covering an area over 20 square kilometers, and potential to demonstrate an expansion of the resource in the near term with past and proposed drilling, is quite an astounding feat for CMC. We plan to initiate drilling at Gavilanes in April, 2024."

The project has a drill permit from SEMARNAT to complete up to 4,650 meters of drilling. Plans are underway to complete 3,000 meters of step-out drilling from the identified resource as recommended by the 2021 NI 43-101 study. Phase 2 of the project envisions an additional 15,000 meters of diamond drilling targeted at a resource expansion program and proposes to conduct drilling during that program in all three mineralized zones on the property, including the Gavilanes, Central and Western Zones.

Surface rights in the core area are held by the Ejido Los Gavilanes, a communal agrarian cooperative who have established exploration agreements with previous operators. The Company has already had met with the Ejido and has initiated negotiations for an exploration agreement which they hope will be concluded in the next couple of months.
