C3 METALS CONFIRMS BORNITE MINERALIZATION AT PROVOST PORPHYRY AT BELLAS GATE, JAMAICA; INTERSECTS 281 METRES AT 0.37% COPPER AND 0.21 G/T GOLD (0.51% CUEQ1), INCLUDING 62 METRES AT 0.50% COPPER AND 0.39 G/T GOLD (0.77% CUEQ1)

C3 Metals Inc. has released assays from two additional holes drilled at the Provost porphyry target on the company's 100-per-cent-owned Bellas Gate project in Jamaica. Drill hole PVT0825-001 (596.7 metres) intersected 280.7 m at 0.37 per cent copper and 0.21 gram per tonne gold (0.52 per cent CuEq) from 227.0 m, including 61.7 m at 0.50 per cent copper and 0.39 g/t gold (0.77 per cent CuEq) from 446.0 m. To date, approximately 5,200 m of an 8,500 m drill program have been completed. Assays are pending for multiple holes, and drilling remains continuing with two rigs.

Bornite and hypogene chalcocite mineralization as well as potassic alteration were confirmed at approximately 500 m depth. The company believes it is possible that PVT0825-001 clipped the top of the bornite core of the porphyry system. PVT0825-001 was drilled with C3 Metals' man-portable drill rig to a record depth of 596.7 m for this rig. The presence of bornite mineralization and potassic alteration corresponded with a spike in grades to 1.14 per cent copper and 1.19 g/t gold (1.98 per cent CuEq) over a 2.5 m interval. Therefore, the company has planned a follow-up drill hole utilizing its larger-capacity contract drill rig, which has depth capacity of more than 1,000 m. The company is currently defining the dimension and grade of copper-gold mineralization in an initial 900 m by 200 m target area that remains open in multiple directions and at depth.

Provost drilling highlights:

• Drill hole PVT0825-001 intersected 280.7 m at 0.37 per cent copper and 0.21 g/t gold (0.51 per cent CuEq) from 227.0 m, including 61.7 m at 0.50 per cent copper and 0.39 g/t gold (0.77 per cent CuEq) from 446.0 m;
• Full transition from pyrite to chalcopyrite-pyrite to bornite mineralization intersected for the first time at the Bellas Gate project;
• A 2.5 m interval of potassic alteration with associated bornite mineralization assayed 1.14 per cent copper and 1.19 g/t gold (1.98 per cent CuEq) from 503.0 m, which is interpreted as the top of a bornite-rich potassic altered core of the Provost porphyry system;
• Deeper drilling is planned to test below hole PVT0825-001 for extensions of these high grades;
• Copper-gold mineralization successfully extended 150 m vertically below earlier drill hole PVT0900-002, which intersected 390.7 m at 0.37 per cent copper and 0.19 g/t gold (0.50 per cent CuEq) from 64.1 m (see press release dated Sept. 25, 2023);
• Drill hole PVT0900-004 intersected 170.1 m at 0.31 per cent copper and 0.16 g/t gold (0.42 per cent CuEq) from 68.1 m; the hole terminated in 0.30-per-cent-copper mineralization within a fault zone at 300 m depth.

Dan Symons, president and chief executive officer, stated: "Provost looks increasingly like a classic, fully intact copper-gold porphyry. The results from PVT0825-001 are very important for multiple reasons: (1) it extends copper-gold mineralization 150 m at depth; (2) the first bornite mineralization and potassic alteration was encountered; and (3) the ratio of sulphide mineralization transitions from pyrite to chalcopyrite to bornite as we go deeper into the system. With this transition, the grades of both copper and gold increase. We plan to prioritize a deep hole to test below PVT0825-001 into the interpreted core of the system. After closing an oversubscribed and upsized private placement of $8.05-million earlier this month, we are well funded to expand our drilling program and provide continuous news flow from the drill bit."

Drill summary

C3 Metals has identified 16 porphyry and 40 epithermal targets across a 30km strike extent within its contiguous mineral concession package in Jamaica. Most historical drilling, while limited, was conducted in the Bellas Gate project area. This historical drilling was relatively shallow, averaging 225m depth with approximately 40 per cent of holes ending in mineralization. The company's current drilling objectives are twofold: 1) test the strike extent of near-suface mineralization, and 2) test the high grade potential at depth by locating the bornite-rich potassic altered cores typically found in economic porphyry systems.

Drilling at Provost continues to define a well-developed porphyry and epithermal copper-gold system that displays classic porphyry style alteration and mineralization zonation. The company has successfully intersected porphyry and epithermal style mineralization along 400m of strike length and approximately 550m down dip. Provost remains open in multiple directions and at depth.

PVT0825-001 extends the northwest striking mineralized zone an additional 150m down dip and, more importantly, confirms the presence of high-grade, bornite-hosted copper mineralization. The upper levels of PVT0825-001 intersected andesite volcanics with kaolinite alteration overprinting illite-chlorite alteration, interpreted as advanced argillic alteration. Below this upper leached zone, is high-grade porphyry copper-gold mineralization and epithermal style base and precious metal mineralization with locally well-developed porphyry quartz stockwork and sheeted B-veins.

Next Steps

C3 Metals is actively drilling with two rigs. The company's owned man-portable rig continues to evaluate the near-surface tonnage potential of porphyry mineralization at Provost, where the system remains open in multiple directions and at depth. A larger capacity contract rig is currently drilling the Camel Hill area of the Bellas Gate project (Figure 4). Upon completion of its current drill hole, this contract rig will move immediately to Provost to test for a high-grade bornite-rich potassic core beneath hole PVT0825-001 reported above.

The company is undertaking real-time geologic modeling, regional and prospect scale structural interpretation, petrology work, geochronology and numerous other exploration studies at Provost and the overall Bellas Gate project area.

C3 Metals looks forward to providing further updates as drilling progresses and anticipates a steady flow of assay results.

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 per cent passing 10 mesh (2mm), and a 250g split was pulverized to 85 per cent 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 per cent). 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 per cent of the submitted samples are quality control samples. No data quality problems were indicated by the QA/QC program.

1 Copper equivalent (CuEq) calculation is for reporting purposes only and was determined based on CuEq ( per cent) = Cu ( per cent) + ((0.7079 * Au g/t) under metal price assumptions of Copper - US$3.00/lb, Gold - US$1,800/oz. As the Bellas Gate project is an early-stage exploration project and there is insufficient metallurgical data to allow for estimation of recoveries, porphyry copper-gold recoveries are estimated based on multiple comparable porphyry-style copper-gold deposits (Alumbrera, Batu Hijau, Fish Lake, Mt Milligan, El Pachon, Agua Rica, Cerro Casale and Skouries) which averaged 90 per cent recovery for copper and 73 per cent for gold.
