C3 Metals Inc. announced rock chip assay results up to 35.8 g/t gold from a comprehensive mapping and sampling program on the Company's 100% owned Main Ridge project in Jamaica. The 3,000-hectare Main Ridge project is contiguous with and approximately 15 kilometres to the west of C3 Metals' previously announced discovery of an outcropping, large-scale epithermal vein swarm within its 100% owned 6,000-hectare Arthurs Seat project, where drilling is underway. High-grade Main Ridge rock chip samples are similar in style to and less than one kilometre from the past producing Pennants Gold Mine.

The Pennants Gold Mine was operated from 2002 to 2004 on a reported non-compliant NI 43-101 historical mineral resource of 75,500 tons at 20.4 g/t gold. The operator reported historical high- grade drill intersections of 1.7m at 430.0 g/t gold and 4.6m at 25.6 g/t gold from the mine property (drill results are historical in nature and have not been independently confirmed). C3 Metals recently expanded its surface mapping and sampling program to cover the entire 6,000- hectare Arthurs Seat concession, the northern area of the Bellas Gate concession and the 3,000-hectare Main Ridge concession.

Results from the ongoing program and previous field exploration programs at Main Ridge have identified multiple gold and copper targets with similar mineralization styles to those identified at Arthurs Seat. A total of 941 rock chip and channel samples have been collected to date with 59 rock samples reporting over 0.10% copper (up to 18.5% copper) and 83 samples reporting over 0.10 g/t gold (up to 35.8 g/t gold). The Company received drill permits for Arthurs Seat two months after application and commenced a planned 25-hole, 5,000m diamond drill program during December 2022.

Arthurs Seat is a grassroots discovery of an 8.0km by 4.5km copper-gold-silver mineralized footprint that has never been drill tested. Within the southeast portion of this mineralized footprint sits an outcropping epithermal vein swarm mapped and sampled over a 5.0km by 3.0km area. The Company has collected thousands of samples at Arthurs Seat and previously announced rock chip assays up to 58.1 g/t gold, 16.5% copper and 4,890 g/t silver.

To date, four of the planned 25 drill holes have been completed. Assays are pending for the first two holes with the third and fourth holes being prepared for shipment to the assay lab. The Company is continuing an aggressive mapping and sampling program along the 20km trend of the CRFZ, from the northern portion of Bellas Gate, through Arthurs Seat to Main Ridge.

Surface mapping and sampling will continue over the coming months to define drilling priorities.
