C3 Metals Receives Drill Permit for Main Ridge

Copper-Gold Project in Jamaica

Main Ridge Immediately Adjacent to Past Producing Pennants

Gold Mine

Toronto, Ontario--(Newsfile Corp. - May 2, 2023) -

C3 Metals Inc.

(TSXV: CCCM) (OTCQB: CUAUF)

("C3 Metals" or the "Company") is pleased to announce it has obtained approvals to commence

exploration drilling at its 100% owned Main Ridge Project in Jamaica.

The Main Ridge Project covers

3,000-hectares and is located immediately adjacent to the past producing Pennants Gold Mine and to

the west of the Company's Arthurs Seat Project (Figure 1).

The Main Ridge drill permit is valid through

April 2028.

Dan Symons, President & CEO, stated

, "With the Main Ridge Project drill permit in hand, we now have

valid drill permits through at least mid-2027 along a 30km of strike extent where we have identified 16

porphyry and 40 epithermal targets.

At Main Ridge, we have identified two separate mineralized

structures over 4km either along trend or in close proximity to the past producing Pennants Gold

Mine.

The Pennants Gold Mine was an open pit mine that operated from 2002 to 2004.

The Main

Ridge Project surrounds the Pennants pit to the west, north and east.

We have identified nine

epithermal and two porphyry targets at Main Ridge that warrant further exploration."

About the Past Producing Pennants Gold Mine

The Pennants Gold Mine was operated as an open pit mine from 2002 to 2004 on a reported non-

compliant NI 43-101 historical mineral resource of 75,500 tonnes at 20.4 g/t gold

.

The operator

reported historical high-grade drill intersections of

1.7m at 430.0 g/t gold

and

4.6m at 25.6 g/t gold

from the mine property (drill results are historical in nature and have not been independently confirmed)

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.

Samples are analysed by 4-Acid digest ICP-MS finish for 63 elements, including pathfinder REE

elements with pulps from samples reporting greater than 1.0% copper being re-assayed by the ore

grade method.

Gold is analysed by 30g Fire Assay AAS finish, with pulps from samples reporting

greater than 5ppm re-assayed by 1kg Screen Fire Assay.

The Company inserts blanks and certified

reference standards in the sample sequence for quality control.

Data from the above drill results are reported historical results and it is unknown what type of quality-control programs were performed at the time.

C3 Metals' QP also advises that true width of the above results cannot be determined at this time.

2

The mineral resourced cited above is presented as a historical estimate and uses historical terminology which does not conform to current National

Instrument 43-101 ("NI 43-101") standards.

A qualified person has not done sufficient work to classify the historical estimate as current mineral

resources or mineral reserves.

Although the historical estimates are believed to be based on reasonable assumptions, these estimates were

calculated prior to the implementation of NI 43-101.

As these historical estimates do not meet current standards as defined under sections 1.2 and

1.3 of NI 43-101, C3 Metals is not treating the historical estimate as current mineral resources or mineral reserves and the historical estimate is

adjacent to and not located within mineral tenure under licence to C3 Metals.
