C3 Metals Continues Expansion of Gold-Copper System at Arthurs Seat, Jamaica

Epithermal style quartz veining has now been mapped and sampled over a 5.0 km by 3.0 km area, occurring within a much broader 8.0 km by 4.5 km footprint of copper-gold-silver mineralization. Geologists have recently discovered epithermal-style sheeted quartz veins south of the Crawle River-Rio Minho Fault Zone ("CRFZ").

An initial 5,000 m drill program comprised of 25 holes from 10 drill pad locations has been designed to test the vertical and lateral continuity of gold-copper mineralization. A drilling application has been submitted for Arthurs Seat, and C3 Metals intends to commence drilling immediately once permits are received.

Arthurs Seat Exploration Highlights:

• Copper-gold-silver mineralized zone expanded to 8.0 km by 4.5 km, including 113 rock chip assays grading greater than 1% copper (see Figure 1)
• Epithermal quartz vein and breccia zone expanded to 5.0 km by 3.0 km, including 28 rock chip samples grading greater than 1 g/t gold (see Figure 2)
• Latest batch of rock chip samples assayed up to 29.8 g/t gold and 5.7% copper
• Epithermal quartz veins confirmed south of the important CRFZ
• Multiple, discrete zones of high-grade copper-silver expanded in the northwest project area
• Copper-gold mineralization confirmed over 30 km between Bellas Gate - Arthurs Seat - Main Ridge

Dan Symons, President and CEO stated, "When we first announced the grassroots discovery of an outcropping epithermal vein swarm at Arthurs Seat less than two months ago, we had mapped veins to a 3.0 km by 2.0 km area within a much broader 7.0 km by 4.0 km copper-gold-silver footprint. In a very short period of time, the vein swarm has now been expanded to a 5.0 km by 3.0 km area within an 8.0 km by 4.5 km footprint. Furthermore, the discovery of veins south of the CRFZ opens up the possibility for the epithermal system to continue on to our Bellas Gate and Main Ridge Projects. Incidentally, our search for historical records indicates C3 Metals is the first company to discover and evaluate this district scale mineralized system."

Geological mapping, supported by spectral interpretation and radiometric survey data, expanded the zone of epithermal gold-copper veining to 5.0km by 3.0km. Assays from epithermal style quartz veins reported up to 29.8 g/t gold, which also contain significant secondary copper species (see Figure 3). Multiple, discrete zones of high-grade copper mineralization occur to the northwest of the epithermal gold-copper vein swarm, returning up to 5.66% copper and 14.4 g/t silver in the latest batch of rock chip assays.

The recent discovery of epithermal quartz veins to the west and south of the important CRFZ suggests the potential to expand the epithermal mineralization further. C3 Metals has now expanded its successful mapping and sampling program to cover the entire 6,000-hectare area of the Arthurs Seat concession and the northern area of the Bellas Gate concession.

ABOUT C3 METALS INC.

C3 Metals Inc. is a junior minerals exploration company focused on creating substantive value through the discovery and development of large copper and gold deposits. The Company holds the 26,800 hectare Jasperoide project in the prolific high-grade Andahuaylas-Yauri Porphyry-Skarn belt of Southern Peru. 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 of Jamaica. Mining 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.
