C3 Metals Discovers High Grade Copper - Silver at Arthurs Seat, Jamaica

C3 Metals Inc. (TSXV: CCCM) ("C3 Metals" or the "Company") is pleased to report surface reconnaissance results from mapping and sampling at the Arthurs Seat Project in Jamaica (Figure 1). Arthurs Seat is one of four Jamaican projects owned 100% by the Company and is located adjacent to the Company's Bellas Gate property where the Company has commenced a 5,000 metre drill program.

Exploration to date at Arthurs Seat has defined a 6.75 km² prospective area of copper mineralized veins and breccias interpreted to represent the upper part of an underlying porphyry system. Magnetics, mapping and detailed prospecting are continuing.

Exploration Highlights:

• Assays up to 13.8% copper and 492g/t silver; 11 rock samples >4% Copper
• 55 copper mineralized samples collected over 4.5km by 1.5km
• Multiple zones of primary and secondary copper mineralization highlights significant potential for a high-grade, intermediate high-sulphidation epithermal copper deposit

Kevin Tomlinson, President and CEO of C3 Metals commented;

"Additional to our drill program in progress at Jasperoide in Peru, we have commenced drilling the highly compelling Epidote Ridge copper-gold porphyry target within the Bellas Gate SEPL, Jamaica. Separately, our small exploration team in Jamaica is also prospecting and sampling a number of tenements that have not been explored for over 40 years. The discovery of widespread copper mineralization including some exceptional high-grade samples at Arthurs Seat is a testament to the prospectivity of our Jamaica tenement package. As the drill program at Bellas Gate progresses, we will continue surface exploration at Arthurs Seat and other high potential prospects. We look forward to providing further updates as results are received."

Exploration Background and Update

The Arthurs Seat Special Exclusive Prospecting License ("SEPL") is situated directly over the regionally significant Crawl River Fault Zone and associated splays, a major structure controlling copper-gold mineralization in Jamaica. Mining was undertaken by the Spanish in the 16th Century and the British in the 19th Century. No modern-day exploration has been carried out within the Arthurs Seat SEPL since a reconnaissance program was conducted by Noranda Inc. in the mid 1960's. A stream/heavy mineral sampling program funded by the Canadian International Development Agency (CIDA) was completed in the 1980's.

Arthurs Seat is contiguous to our highly prospective Bellas Gate SEPL, where at least 12 porphyry prospects have been confirmed along Porphyry Alley and where the Company has commenced a 5,000-metre diamond drilling program to test a number of compelling copper-gold targets (see press release dated May 27, 2022).

The Company recently completed geological mapping and prospecting over a 10 km² area in the eastern part of Arthurs Seat. A total of 103 rock samples were collected from mineralized intermediate sulfidation style epithermal quartz veins and breccias that cross-cut andesitic volcanic-volcaniclastic rocks and Cretaceous aged limestones of the Arthurs Seat Formation. Copper mineralization comprises primary bornite, tennantite-tetrahedrite and associated secondary copper species including native copper (Figure 2). Of the 103 samples collected, 55 assayed greater than 0.15% copper with numerous samples of both outcrop and float reporting high grades up to 13.8% copper and 492g/t silver (Figure 3, Table 1).

Geological mapping and prospecting will continue at Arthurs Seat and ridge/spur soil sampling has been initiated over the eastern SEPL area. The team is assessing the rock sample results in conjunction with new mapping to formulate plans for ground geophysics and drill testing.

Additional updates are planned as information and assays are received.

ABOUT C3 Metals Inc.

C3 Metals Inc. is a junior minerals exploration company focused on creating substantive value for its shareholders through the discovery and development of large copper and gold deposits. The Company's flagship project is the 57km² Jasperoide high-grade copper-gold skarn and porphyry system located in the prolific Andahuaylas-Yauri Porphyry-Skarn belt of southern Peru. Mineralization at Jasperoide is hosted in a similar geological setting to the nearby major mining operations at Las Bambas (MMG), Constancia (Hudbay) and Antapaccay (Glencore). C3 Metals also holds a 100% interest in five licenses covering 207km2 of highly prospective copper-gold terrain in Jamaica and a 2% royalty in Tocvan's Rogers Creek project.
