C3 Metals Drilling Confirms Epithermal and

Porphyry Targets at Arthurs Seat

At Least 16 Porphyry and 40 Epithermal Prospects to Evaluate

in Jamaica

Toronto, Ontario--(Newsfile Corp. - March 23, 2023) -

C3 Metals Inc.

(TSXV: CCCM) (OTCQB:

CUAUF) ("C3 Metals" or the "Company") is pleased to announce results from its initial scout drilling

program at the Company's 100% owned Arthurs Seat Project in Jamaica.

The Arthurs Seat Project is

contiguous with C3 Metals' 100% owned Bellas Gate and Main Ridge Projects to the southeast and

west, respectively (Figure 1).

Ten scout holes tested extensive epithermal quartz breccias exposed north

of the Crawle River-Rio Minho Fault Zone ("CRFZ"), a new and emerging porphyry - epithermal belt.

There is no record of any previous drilling at the Arthurs Seat Project.

Although first pass drilling did not

intersect high-grade shoots that are common to these systems, broad zones of lower grade gold

mineralization with small intervals of high grade (0.60m at 7.63 g/t Au) have been confirmed within

telescoped porphyry-style alteration and mineralization.

Dan Symons, President and CEO, stated

, "This first pass scout drilling has provided us with a much

better understanding of the district scale mineral system we are exploring between Bellas Gate and

Arthurs Seat.

The data collected at Arthurs Seat to date suggests that the extensive gold and copper

mineralized epithermal vein system we discovered is sitting above multiple additional porphyry

targets.

This is supported by the presence of strong geophysical and geochemical anomalies

overlapping with porphyry-style alteration in spectral mapping.

Importantly, we have now encountered

highly anomalous gold-copper-molybdenum in the first scout holes drilled in the history of this project

area.

"When we step back and evaluate our Jamaican portfolio, we now have 16 porphyry and 40 epithermal

targets over a 30km strike after only nine months of new data collection and interpretation of historical

data.

We intend to begin systematically drill testing the highest priority targets along what we believe is

an emerging porphyry and epithermal belt."

Highlights

Epithermal gold mineralization in quartz breccias is telescoped by porphyry mineralization.

Coarse gold identified in drill hole ARS5850-002 assayed 7.63 g/t over 0.60 m (Figure 2).

Spectrometer studies confirm both epithermal and porphyry style alteration mineralogy.

Illite alteration is consistent with low-sulphidation epithermal systems.

Pyrophyllite alteration - a key alteration mineral in porphyry systems.

Porphyry vectors identified include:

Magnetite veins and deformed porphyry B-Veins, with chalcopyrite and bornite.

Leached diorite with interpreted B-veins and interlayered pyrophyllite vermiculite clay.

Discrete Total Magnetic Intensity anomalies proximal to pyrophyllite zone (Figure 3).

Extends the copper-gold epithermal-porphyry district over 30km from Belles Gate through to

Arthurs Seat and Main Ridge with 16 porphyry and 40 epithermal prospects outlined to date.

Drilling Summary

Mapping and sampling defined an 8.0km by 4.5km copper-gold-silver footprint within which a 5.0km by

3.0km high-density, low-intermediate sulphidation epithermal quartz breccia swarm occurs.

The

Company completed 10 scout drill holes for 2,200m, testing multiple high potential epithermal gold

targets.

Eight of 10 holes intersected epithermal and/or porphyry style mineralization, and two holes were

lost due to ground conditions.

Drill assays confirm lower grade epithermal gold mineralization over narrow and broad widths.

Locally

coarse gold occurs in association with bornite and pyrite mineralization (Figure 2), which reported 7.63

g/t gold over 0.60 metres within a broader zone of 0.28 g/t gold over 29.4 metres.

Epithermal gold

mineralization in quartz breccias is telescoped by hydrothermal alteration which appears to be sourced

from an interpreted porphyry at depth.

Copper is late and occurs as bornite with lesser chalcopyrite

coating fractures and as disseminations.

Molybdenum is highly anomalous in several drill holes with

8.3m assaying at 46ppm molybdenum in ARS4950-002.

Molybdenum is a key porphyry indicator.

Next Steps

C3 Metals is in a unique position to evaluate and unlock significant value from the multiple high potential

porphyry and epithermal targets identified along this newly emerging porphyry - epithermal belt.

The

Company has been granted two 5-year drilling permits for the Arthurs Seat and Bellas Gate Projects and

expects to receive the Main Ridge Project drill permit during the first half of 2023.

A district-wide drill

program is required to properly evaluate each of the high potential porphyry and epithermal targets at

Bellas Gate, Arthurs Seat and Main Ridge.

The next phase of drilling in Jamaica will systematically evaluate high potential porphyry and epithermal

prospects delineated.

Much of the historical drilling at the Connors, Camel Hill, Geo Hill, Hendley and

Provost porphyry targets (Figure 1) was undertaken prior to geophysical data but confirmed moderate to

strong copper-gold mineralization on the margins of each system.

Several historical drill holes ended in

mineralization and porphyry targets remain open along strike and at depth.

Overlying the historical

drilling on the modelled magnetic and IP chargeability geophysical data has proven to be a key targeting

tool for copper-gold porphyry-style mineralization.

Historical highlights include (refer to press releases

August 30, 2021 and January 12, 2017):

Connors

114.0m @ 0.69% Cu, 0.52g/t Au in CON-14-004 (from 28.0m)

1

Camel Hill

137.2m @ 0.56% Cu, 0.25g/t Au in CAM92-01 (from surface)

1

Provost

339.0m @ 0.28% Cu, 0.12g/t Au in PVT-16-002 (from 29m)

1

Geo Hill

121.6m @ 0.35% Cu (gold not assayed) in GEO92-01 (from 39.6)

1

Hendley

261.0m @ 0.35% Cu in HEN-15-003 (from 59.0)

With respect to porphyry potential, C3 Metals plans to systematically test the surface extent and depth

potential of the known mineralization and to test for higher grade bornite-rich cores to the systems at

Connors, Camel Hill, Geo Hill, Hendley and Provost (Figure 4).

Other high potential porphyry targets are

being evaluated at Bellas Gate, Arthurs Seat and Main Ridge, and will be drill tested if warranted.

The

Company is currently in discussions with several drill contractors.

Figure 4: Coincident strong magnetic and IP chargeability anomalies have been confirmed on five

porphyry targets with historical drilling. C3 Metals interprets these larger, deeper coincident geophysical

anomalies to represent the higher-grade mineralized core of the porphyry system and intends to drill test

them as soon as is practically possible.

The Spanish and British excavated over 60 adits and shafts at Bellas Gate during the 1600s and 1800s

respectively, targeting high grade epithermal gold, silver and copper veins (Figure 5).

The Company

plans to evaluate these and other high priority epithermal targets using a recently purchased low-cost,

diamond drill rig that is expected to be operational by mid-2023.

It is capable of drilling to 400 metres

depth.

Epithermal targets will be evaluated across the 30km epithermal corridor that extends from Bellas

Gate through to Arthurs Seat and Main Ridge.

Epithermal drilling costs are expected to be at least 50%

lower than porphyry drilling.

Figure 5:

Examples of adits located in proximity to porphyry targets. To date, 62 historical adits and

shafts have been located in close proximity (0.5km to 3.0km) from 12 of 16 identified porphyry targets.

Work has now commenced to incorporate these prospects into the exploration framework.

Dan Symons, President and CEO, continued

, "With so many high-priority porphyry and epithermal

targets generated in such a relatively short period of time, combined with the size of our mineral

concession package, it is clear we are sitting on a new, underexplored porphyry - epithermal district.

With multiple drill holes ending in good grade porphyry copper-gold mineralization, a drill rig with

greater depth capability is required.

We are currently working to source suitable equipment to

recommence drilling our highest priority targets.

Subject to results and market support, our longer-

term intention is to aggressively explore this new and exciting district-scale, copper-gold porphyry and

epithermal belt using multiple, company-owned drill rigs to test the epithermal targets and a larger,

contract rig to test the porphyry targets."
