C3 Metals Inc. reported 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 g/t Au, 5.2% Cu and 53 g/t Ag. The Arthurs Seat project is in the highly prospective Crawle River-Rio Minho Fault Porphyry and Epithermal District of Jamaica.

An extensive area of epithermal veins and breccias 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. 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, 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.
