C3 METALS INTERSECTS 280M AT 0.43% COPPER AND 0.24 G/T GOLD (0.60% CUEQ1) WITHIN 391M OF PORPHYRY COPPER-GOLD MINERALIZATION; BROADEST MINERALIZED INTERVAL EVER REPORTED AT BELLAS GATE, JAMAICA

C3 Metals Inc. has received assays for the final 130.7 metres (m) of drill hole PVT0900-002. Assays for the first 350.0m were reported on September 12, 2023.

Drill hole PVT0900-002 intersected 390.7m at 0.37% copper and 0.19 g/t gold (0.50% CuEq1) from 64.1m, including 279.5m at 0.43% copper and 0.24 g/t gold (0.60% CuEq1). This is the broadest interval of copper-gold mineralization reported to date at the Company's 100% owned Bellas Gate project in Jamaica.

Ongoing drilling will continue evaluating a cluster of discrete high priority porphyry copper-gold targets. C3 Metals is drill testing both the strike and depth potential of these porphyry targets with two goals: adding potential near-surface mineralized material tonnage and locating the bornite-rich potassic altered higher-grade core found in most economic porphyry systems. These targets are defined by coincident alteration, geochemistry and geophysics anomalies along the two parallel Camel and Connors porphyry belts at the Bellas Gate project (Figure 1). Approximately 2,500m of a fully funded 8,500m drill program has been completed to date.

Drilling Highlights

Longest interval of copper-gold mineralization ever intersected at the Bellas Gate project.390.7m at 0.37% copper and 0.19 g/t gold (0.50% CuEq1) from 64.1m, including 279.5m at 0.43% copper and 0.24 g/t gold (0.60% CuEq1) intersected in drill hole PVT0900-002.PVT0900-002 terminated in highly altered diorite and andesite cut by pyrite - magnetite plus or minus chalcopyrite plus or minus molybdenite in veins, with an intense anhydrite overprint. Drill holes PVT0900-003 (418.6m) and CMH8350-001 (662.0m) completed - assays pending.Two additional drill holes are well advanced.Multi-phase system - Porphyry style alteration and mineralization is overprinted or telescoped by intermediate and high-sulphidation epithermal copper-gold mineralization.

Dan Symons, President and CEO, stated, "Over the last 10 months we have systematically mapped approximately 12,000 hectares of our 20,700-hectare mineral concession package in Jamaica in order to develop a comprehensive model and 3D understanding of the geology at Bellas Gate. The fact that we have intersected the broadest interval of copper-gold mineralization ever in the history of the project in only the second hole of the ongoing drill program speaks to the quality of work performed by our geology team.

"We will continue to evaluate both the strike and depth extent of the multiple porphyry clusters discovered along the Camel and Connors belts, which we suspect may converge at depth into a larger hydrothermal system. We expect to have a steady flow of assay results to report from the ongoing 8,500m drill program into 2024. Continued positive results will see us move to extending the program. With copper sulphide mineralization visually present in the first six holes of the program, we believe we are at the beginning of a significant copper-gold discovery in Jamaica."

Drilling at the Provost porphyry target confirms a telescoped, almost fully intact, and non-eroded porphyry copper-gold system. This system is interpreted to be spatially associated with a larger porphyry system at depth, as illustrated in cross section (Figure 3). Mineralization comprises chalcopyrite and pyrite in strongly phyllic to potassic altered diorite and andesite volcaniclastics (Figure 4). Table 1 summarizes significant drill intersections. Pervasive anhydrite alteration is observed at approximately 400m depth, as veins and infill, locally associated with chalcopyrite mineralization. The presence of strong anhydrite alteration and the multi-phase overprinting of epithermal veins telescoped onto an existing porphyry are positive indicators. Drill results continue to support the interpretation of a well-developed and fertile hydrothermal system. C3 Metals will continue to explore for bornite-rich copper mineralization that is commonly central to most porphyry systems.

Next Steps

Recent and historical drilling at Provost confirms porphyry and epithermal copper-gold mineralization is open in most directions. C3 Metals owns a man-portable drill rig that is currently stepping out along strike and at depth at Provost. Based on surface geologic mapping, historical and recent drilling results, the Provost porphyry target currently measures 1,500m in length, averages 350m in width, and has a confirmed depth extent of at least 400m. Planned drilling at Provost is designed to systematically test along strike of this coincident geology, geophysics and geochemical anomaly.

The larger capacity contract drill rig is currently drilling approximately 3.5km southeast of Provost at the Camel Hill porphyry target. The Camel Hill porphyry target currently measures 1,800m in length and 1,000m in width and is defined by a coincident geology, geophysics and geochemical anomaly. The first hole was planned to a depth of 450m but was extended to 662m due to the presence of strong pyrite, lesser chalcopyrite and favorable porphyry-style alteration below the original target depth (assays pending). A second hole is currently in progress with a target depth of approximately 500m. These holes provide structural, geochemical, alteration and mineralization data to aid in targeting the bornite-rich potassic altered core found in most economic porphyry systems. Four deep holes (700m - 1,000m) are currently planned along the Camel and Connors porphyry belts.

The Company looks forward to providing further updates as drilling progresses and anticipates a steady flow of assay results.

ABOUT C3 METALS INC.

C3 Metals Inc. is a mineral exploration company focused on creating substantive value for its shareholders through the discovery and development of large copper and gold deposits. The Company is actively exploring in Jamaica where it has identified 16 porphyry and 40 epithermal prospects over a 30km strike extent across its 20,700 hectare exploration licences package. Mining is currently the second largest industry in Jamaica, and historical mining dates back to the colonial eras of the 1500s (Spanish) and 1800s (British). The Company also holds approximately 24,000 hectares located 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). At Jasperoide, the Company has identified over 15 skarn prospects and an outcropping porphyry system over two parallel 28km belts. The Company has published a maiden resource estimate on the first of these skarn targets, which contained Measured & Indicated Resources of 52Mt at 0.5% copper and 0.2 g/t gold.

Stephen Hughes, P.Geo. is Vice President Exploration and a Director for C3 Metals and is a Qualified Person as defined by National Instrument 43-101. Mr. Hughes has reviewed the technical information in this news release and approves the written disclosure contained herein.

Technical Program

C3 Metals adheres to a strict QA/QC protocol for handling, sampling, sample transportation and analyses. Chain-of-custody protocols are designed to ensure security of samples until their delivery at the laboratory.

Samples were cut at C3 Metals' operations base in Bellas Gate, St Catherine, Jamaica by Company personnel. Diamond drill core was sampled in maximum 3-metre intervals, stopping at geological boundaries, and using a rock saw. Core diameter is a mix of HQ3 and NQ3 depending on the depth of the drill hole. Samples were bagged, tagged and packaged for shipment by DHL air freight service to the ALS preparation laboratory in Sudbury, Ontario, Canada where entire samples were crushed to 70% passing 10 mesh (2mm), and a 250g split was pulverized to 85% passing 200 mesh (75microm).

The prepared samples were sent to the ALS assay laboratories in Vancouver, Canada for copper, gold and silver assays, and multi-element ICP. ALS is an accredited laboratory which is independent of the Company. Gold assays were by fire assay fusion with AAS finish on a 30g sample and the overlimit gold assay was completed by fire assay and gravimetric finish on 30g sample. Copper and silver were assayed by ICP-AES following a 4-acid digestion on the ME-ICP61 package for a suite of 33 elements and the over limit copper by 4-Acid digestion and assayed by ICP-AES on each sample with copper greater than 10000ppm (1%). Copper and gold standards as well as blanks and duplicates (coarse crush split) were randomly inserted into the sampling sequence for quality control. On average, 9% of the submitted samples are quality control samples. No data quality problems were indicated by the QA/QC program.
