C3 Metals Intersects 309.0 Metres at 0.44% Copper and 0.33 g/t Gold in First Assays from Bellas Gate Project, Jamaica

Toronto, September 12, 2022 - C3 Metals Inc. (TSXV: CCCM) (OTCQB: CUAUF) ("C3 Metals" or the "Company") is pleased to announce it has intersected 309 metres at 0.44% Cu and 0.33 g/t Au beginning 15 metres down hole. This result is from 330 metres of a 703 metre drill hole at the Company's 100% owned Bellas Gate Project in Jamaica. Two additional holes have been completed at the Epidote Ridge target (assays pending) within Bellas Gate. The total program is anticipated to be 5,000 metres. Bellas Gate, as well as C3 Metals' other projects in Jamaica, sit within the highly prospective Crawle River-Rio Minho Fault Porphyry and Epithermal District ("CRF District").

Dan Symons, President & CEO, of C3 Metals stated, "Although these assay results represent less than half the first drill hole of a five-hole program, we felt it prudent to immediately announce the results given the outstanding continuity and grades of the copper and gold minerilzation reported to date. The Bellas Gate Project sits within the CRF District, a major structural break which cuts across Jamaica and is known to host multiple porphyry systems. Our understanding of the Epidote Ridge system within Bellas Gate has been significantly advanced by our recent geological mapping and geophysics interpretations, and we believe the target has tremendous potential. These partial assays of the first hole drilled in this target supports our thesis. We look forward to completing the ongoing 5,000m program and receiving all assays."

Drilling Highlights:

• Partial assays received for the first 330m of hole CON9325-001 returned 309.0m @ 0.44% Cu and 0.33 g/t Au from 15.0m.
• Cu-Au grades comparable to many porphyry deposits currently being mined.
• Drilling confirms mineralization is open to the west and at depth.
• Gold rich-porphyry mineralization confirmed and is associated with strong magnetite alteration.
• Geophysics (mag and IP) strongly supports downplunge continuity of mineralized body.
• Two additional holes completed into the Epidote Ridge target (assays pending).
• Drill rig mobilizing to northern end of Epidote Ridge to test a coincident magnetic and IP chargeability anomaly.

To date, three holes have been completed to test the porphyry potential at the Epidote Ridge target, which is centrally located to five porphyry systems: Connors, Camel Hill, Geo Hill, Lucky Valley and Ginger Ridge (Figure 1). The first hole, CON9325-001, tested an interpreted hydrothermal channel way plunging to the east of Connors under Epidote Ridge (Figure 2). The Company is well-advanced on a 5,000-metre core drilling program to test several compelling, high-priority copper and gold porphyry targets.

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 holds the Jasperoide project is located in the prolific high-grade Andahuaylas-Yauri Porphyry-Skarn belt of Southern Peru and covers 27,200 hectares. 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 20,700 hectares of highly prospective copper-gold terrain within the CRF District in Jamaica, where mining history dates to the 1500's and 1800's when Spanish and British mining companies targeted high grade copper in veins. C3 also holds a 2% royalty in Tocvan's Rogers Creek project.
