C3 Metals Discovers Large-Scale Epithermal Gold-Copper Vein System at Arthurs Seat, Jamaica

Rock Chips Assayed up to 14.2 g/t Gold and 5.2% Copper

C3 Metals Inc. (TSXV: CCCM) (OTCQB: CUAUF) ("C3 Metals" or the "Company") is pleased to report the discovery of a large-scale, intermediate sulfidation epithermal gold and copper vein swarm at the Company's 100% owned Arthurs Seat project. First rock chip assays from this discovery returned up to 14.2 gt Au, 5.2% Cu and 53 gt Ag. The Arthurs Seat project is in the highly prospective Crawle River-Rio Minho Fault Porphyry and Epithermal District ("CRF District") of Jamaica.

An extensive area of epithermal veins and breccias (Figure 1) has been outlined on the Arthurs Seat project. Field mapping to date indicates quartz vein and breccia structures up to 25 metres in true width that have been discontinuously traced over two kilometres of strike. This newly discovered vein swarm is located approximately 500 metres southeast of the previously announced high-grade copper-silver mineralization (see assays up to 13.8% Cu and 492 g/t Ag in press release dated June 2, 2022).

Exploration Highlights:

• Epithermal veins and breccias at the Crofts Hill target within Arthurs Seat:
  • A true maiden discovery with no prior modern-day exploration - never drilled;
  • A high density of intermediate sulfidation quartz vein and breccias over an area of 3 km x 2 km;
  • Rock chip assays up to 14.2 g/t Au, 5.2% Cu, and 53 g/t Ag;
  • Over 30% of the initial 137 rock chips collected assayed highly anomalous gold values; and
  • Sheeted quartz vein and breccia zones up to 25m true width.
• Copper-Silver Zone at the Brandon Hill target within Arthurs Seat:
  • Exploration limited to selective surface sampling in the 1960s - never drilled;
  • Recently completed ridge and spur soils confirm a 2.5 km x 1.2 km copper in soil anomaly; and
  • Discovery of amygdaloidal basalts flooded with secondary copper.

Dan Symons, President & CEO, stated, "We believe that the CRF District is a completely untapped district scale play of which C3 Metals holds 20,700 hectares. True greenfields discoveries in this day and age are very rare. We now have two highly prospective targets to evaluate within our Arthurs Seat project. We believe the underexplored nature of our Jamaican projects and the 25 km strike potential of the CRF District represents a compelling opportunity for the Company. Drill permit applications have been filed and are expected to be received in the near term. As soon as the permits for Arthurs Seat drilling are in hand, we intend to commence testing these exciting discoveries."

Exploration Update

The Arthurs Seat project is situated over the regionally significant CRF District, a major mineralizing structure that bisects the island of Jamaica. Very little exploration has been carried out at Arthurs Seat with many areas having never been subject to field mapping and evaluation. Arthurs Seat is contiguous to the highly prospective Bellas Gate project, where C3 Metals is currently undertaking a 5,000-metre diamond drill program and recently announced an intersection of 309.0m at 0.44% Cu and 0.33 g/t Au in the upper portion of the first drill hole of the program (see press release dated September 12, 2022).

C3 Metals' exploration activities continue to identify copper, gold and silver mineral occurrences throughout the Arthurs Seat project. The anomalous geochemical copper-gold-silver footprint has now been expanded to 7 km x 4 km (Figure 1), covering both Brandon Hill through to Crofts Hill. Although various mineralization styles have been identified, an important vein / breccia discovery at Crofts Hill confirms potential for a large-scale and well-preserved epithermal gold vein system.

Epithermal Vein Discovery (Crofts Hill)

The extensive field of intermediate sulfidation epithermal veins and breccia zones up to 25m wide is similar to the Pueblo Viejo epithermal gold-silver deposit in the Dominican Republic with Arthurs Seat epithermal veins are hosted in volcanic and volcaniclastic rocks of Cretaceous Age. Pueblo Viejo has reserves and resources that include proven and probable gold reserves of 5.7 million ounces; measured and indicated gold resources of 15.0 million ounces; and, inferred gold resources of 2.2 million ounces (Source https://mininglifeonline.net/company-article/pueblo-viejo/10531).

Exploration activities undertaken thus far by C3 Metals have consisted of reconnaissance geologic mapping, ridge and spur soil sampling, the collection of representative rock chip and grab samples from different vein styles and spectrometer analyses. Mapping has outlined mineralized quartz veins and breccias over a 3 km x 2 km area at Crofts Hill. Assays have been received for 137 rock chip samples collected at Crofts Hill, with over 30% assaying highly anomalous gold and up to 14.2 g/t Au and 5.2% Cu (Figure 2).

Copper-Silver Zone (Brandon Hill)

The Company continues to discover significant zones of copper mineralization at the Brandon Hill area, comprising secondary copper species (malachite, azurite, brochantite, cuprite and native copper) occurring in conglomerate, volcanic and volcaniclastic rocks. Ridge and spur soil sampling was recently completed over the entire Brandon Hill area and partial assays have outlined a copper in soil anomaly measuring 2.5 km x 1.2 km (Figure 3). Follow-up field mapping in an area of high copper in soils (up to 2780ppm Cu) identified significant secondary copper (brochantite) mineralization in a basalt (Figure 3), assays pending.
