C3 Metals Commences Follow Up Drilling to Expand Porphyry Copper

Mr. Dan Symons reports:

Toronto, Ontario--(Newsfile Corp. - August 8, 2023) - C3 Metals Inc. (TSXV: CCCM) (OTCQB: CUAUF) ("C3 Metals" or the "Company") is pleased to announce that two drill rigs have been mobilized to Jamaica to commence follow up drilling at the Company's highly prospective Bellas Gate copper-gold project in Jamaica. C3 Metals holds a 100% interest in the Bellas Gate, Arthurs Seat and Main Ridge licenses that cover an extensively mineralized porphyry/epithermal copper-gold district along the Crawle River-Rio Minho fault zone ("CRFZ") (Figure 1).

BC Diamond Drilling ("BCDD") have been contracted for a minimum of 6,000 metres of diamond drilling using a drill rig with a depth capacity of greater than 1,000 metres, and C3 Metals has purchased a man-portable rig to drill an initial 2,500 metres testing near surface porphyry and epithermal prospects to a nominal vertical depth of approximately 400 metres.

Dan Symons, President and CEO of C3 Metals commented, "The average depth of all previous drilling is less than 225 metres, and over 40% of all drill holes ended in strong copper-gold mineralization. Airbourne magnetic and IP geophysics data indicate that multiple near-surface porphyries may converge at depth into a very large system. Based on historical drilling, our 2022 drill program and an extensive remapping campaign, we have identified multiple high-level copper-gold porphyries clustered along two discrete northwest trending belts at Bellas Gate.

"We are pleased to announce that two drill rigs have been mobilized to Jamaica: a large rig capable of testing the depth extent of our highest priority porphyry targets, and a Company-owned, man-portable rig that will cost effectively test the near surface strike extent of these porphyry and epithermal systems. The objective of this drilling program is to determine both the extent of the near surface porphyry copper-gold mineralization intersected to date and to test the deeper parts of these systems for a high-grade core. With 16 porphyry and 40 epithermal targets identified over a 30km strike extent, there is no shortage of drill-ready targets. With both rigs now mobilized to Jamaica, we are pleased to announce that the drill program is commencing."

2023 Drilling Program

Historical drilling at Bellas Gate is generally shallow, with an average hole depth of less than 225m for porphyry prospects and less 200m for epithermal vein prospects.

Over the past six months the Company's exploration team undertook detailed mapping across the entire Bellas Gate project. Mapping and structural data was compiled and incorporated into a 3D geology block model, which shows two district-scale structural features referred to as the Connors and Camel belts (Figure 2). Clusters of high-level, copper-gold porphyries occur along each belt, with widespread intermediate-sulfidation epithermal vein style copper, gold and silver mineralization distal to the porphyries.

All known porphyries at Bellas Gate are gold-rich, with chalcopyrite-pyrite mineralization dominantly hosted in volcanic andesite rocks and less commonly in diorite porphyry dykes and stocks. Previous drilling confirms copper-gold mineralization is open at depth and along strike. The current drill program will target higher-grade, bornite-rich mineralization that is typically associated with the core of these systems.

An initial 6,000-metres of deeper drilling (6-8 holes X 700m-1100m in depth) and 2,500-metres of shallow drilling (10 holes X 100m-500m in depth) is planned at Bellas Gate. The objective of planned drilling is two-fold:

Note the three planned drill holes, which will test below broad intersections of copper-gold mineralization in previous drilling where the average drill depth is only 225m.
