C3 Metals Expands Epithermal Gold-Copper Vein System by 1.5 Kilometres at Arthurs Seat, Jamaica

Rock Chips Assayed up to 14.4 g/t Gold, 245 g/t Silver and 11.1% Copper

Toronto, Ontario--(Newsfile Corp. - October 12, 2022) - C3 Metals Inc. (TSXV: CCCM) (OTCQB: CUAUF) ("C3 Metals" or the "Company") is pleased to report it has significantly expanded the previously reported Arthurs Seat, Jamaica epithermal gold-copper vein swarm discovery by an additional 1.5 km to the east of the initial discovery (see press release dated September 13, 2022). The high-density, low-intermediate sulphidation epithermal veins have now been mapped and sampled across a 4.5 km by 2.0 km area. This expansion increases the copper-gold-silver mineralized footprint at Arthurs Seat to an area of 8.0 km by 4.0 km.

A second batch of rock chip samples from the vein swarm assayed up to 14.4 g/t Au, 245 g/t Ag and 11.1% Cu. These results follow previously reported assays up to 14.2 g/t Au, 53 g/t Ag and 5.2% Cu. The swarm of north-south and east-west trending quartz vein and quartz-rich breccias have been mapped proximal to the regionally significant Crawle River-Rio Minho Fault District ("CRF District"), along an emerging fertile belt for porphyry copper-gold and epithermal copper-gold-silver deposits.

Arthurs Seat Exploration Highlights:

  • Copper-gold-silver mineralization expanded to an 8.0 km by 4.0 km area
  • High-density, low-intermediate sulphidation epithermal quartz vein and breccia zone expanded to a 4.5 km by 2.0 km area
  • Individual rock chips assayed up to 14.4 g/t Au, 245 g/t Ag and 11.1% Cu
  • Mineralization includes chalcopyrite, chalcocite, pyrite, bornite, malachite and azurite
  • Drill permit application submitted and progressing

Dan Symons, President and CEO stated, "The Arthurs Seat discovery has now been expanded to an 8.0 km by 4.0 km area, which demonstrates the potential scale of this copper-gold-silver system. Given the sheer size of the CRF District, we believe that this mineralized zone has potential to continue to expand even farther. Within this anomaly, the outcropping, high-density epithermal vein swarm has now been mapped and sampled over a 4.5 km by 2.0 km area. Rock chip assays have returned multiple high-grade results (+14 g/t Au and 5% Cu) from locations 1.5 km apart. We now have eight geologists in the field mapping and sampling to advance this significant target area in advance of drill targeting."

C3 Metals has successfully expanded the footprint of copper-gold-silver mineralization at Arthurs Seat and continues to discover copper-rich structures within the 8.0 km by 4.0 km contiguously mineralized corridor (see Figure 1). Assays from the copper-rich zone to the northwest of the epithermal gold-copper vein swarm have returned up to 13.8% Cu and 492 g/t Ag (see press release dated June 2, 2022).

C3 Metals' ongoing mapping and sampling program has also expanded the significant epithermal quartz vein and breccia system to 4.5 km by 2.0 km. Quartz-rich structures are up to 30m in true width and are comprised of massive quartz veins, quartz breccias and sheeted quartz veins that have been discontinuously traced along strike for over 2.0 km (see Figure 2). The quartz veins and quart-rich breccia zones contain variable percentages of pyrite, chalcopyrite, bornite, malachite and azurite. Rock chip samples have returned numerous high-grade results from epithermal veins, including up to 14.4 g/t Au, 245 g/t Ag and 11.1% Cu.

An extensive mapping and sampling program is currently underway. Over 1,000 rock chips have been sent to Actlabs for analysis. A drill permit application has been submitted for Arthurs Seat, and C3 Metals intends to immediately drill test the epithermal vein swarm once permits are received.

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 of Jamaica, where mining history dates to the 1500s and 1800s when Spanish and British mining companies targeted high grade copper in veins. The Company also holds a 2% royalty in Tocvan's Rogers Creek project.
