C3 Metals Expands Permitted Drill Area by 74% at Jasperoide Copper-Gold Project, Peru

Drill Results

C3 Metals Expands Permitted Drill Area by

74% at Jasperoide Copper-Gold Project, Peru

Toronto, Ontario--(Newsfile Corp. - September 26, 2023) -

C3 Metals Inc.

(TSXV: CCCM) (OTCQB:

CUAUF) ("C3 Metals" or the "Company") is pleased to announce that it has received the Authorization to

Start Activities from the Peruvian Ministry of Energy and Mines for a recently modified Declaration of

Environmental Impact permit (the "Drill Permit").

The modified Drill Permit increases the area permitted for exploration drilling by 74% and consists of an

additional 24 drill platforms and 53 additional drill holes (Figure 3).

This increase to the Drill Permit area

will allow C3 Metals to systematically test two additional skarn targets: Cresta Verde ("CVZ") and

Callejon De Oro ("COZ").

These skarn targets are immediately to the northwest and south of the

Montana de Cobre ("MCZ") skarn deposit.

With positive initial results from an ongoing drill program at

Bellas Gate, Jamaica (see press release dated September 25, 2023), a decision to restart drilling at

Jasperoide is unlikely to be taken until the current drill program at Bellas Gate is completed.

The MCZ deposit hosts the following near surface mineral resources

1

:

Measured & Indicated Mineral Resources - 51.9 million tonnes ("Mt") at 0.50% total

copper and 0.20 g/t gold for 569.1 million pounds of copper and 326,800 ounces of gold.

Measured Mineral Resources

- 28.6Mt at 0.60% total copper, 0.24 g/t gold for 380.0M pounds

of copper and 218,200 ounces of gold.

Indicated Mineral Resources

- 23.3Mt at 0.37% total copper, 0.15 g/t gold for 189.1M pounds of

copper and 108,600 ounces of gold.

Inferred Mineral Resources

- 4.0Mt at 0.32% total copper, 0.11 g/t gold for 28.3M pounds of

copper and 14,600 ounces of gold.

Based on the assumptions and parameters as outlined in the NI 43-101 Technical Report titled "Jasperoide Copper-Gold Project Cusco Region,

Peru" dated July 5, 2023.

Qualified Persons: Michael G. Hester (FAusIMM), Independent Mining Consultants, Inc., Simon Mortimer (M.Sc., FAIG),

Atticus Geoscience Consulting S.A.C. and Adam Johnston (FAusIMM(CP)), Transmin Metallurgical Consultants.

Dan Symons, President and CEO of C3 Metals, commented

, "With the modified Drill Permit approved,

we are now able to continue exploration drilling at our Jasperoide project in Peru, subject to capital

allocation decisions.

The MCZ deposit within the Jasperoide project is the first of 13 copper-gold

skarn targets tested along a 28km magnetite belt.

We believe there is potential for multiple deposits

across this belt similar to MCZ.

Our goal is to prove up additional copper-gold skarn deposits of

similar size and grade to support a 50,000 tonne per annum copper cathode production hub in this

world-class copper-gold district."

The 30,000-hectare Jasperoide project consists of approximately 24,000 hectares titled concessions

and an additional 6,000 hectares that have been approved and are awaiting official title.

This 30,000-

hectare land package sits within 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). The

Haquira copper development project (First Quantum Minerals) is located nearby along with multiple

exploration projects held by large producers (BHP, Barrick, Fresnillio, Rio Tinto and others) (Figure 1).

C3 Metals has identified 13 skarn targets along the Jasperoide belt on the eastern side of its property

and multiple skarns and an outcropping porphyry target on the Khaleesi belt on the western side of its

property (Figure 2).

Since acquiring its initial 5,700 mineral concession package in 2020, C3 Metals has

expanded its mineral concession footprint by 426% to approximately 30,000 hectares.

The Company

views this package as highly strategic given its geologic potential and proximity to multiple operating

mines.

C3 Metals believes that CVZ and the MCZ deposit formed during the same hydrothermal mineralizing

event and are erosion remnants of a larger skarn body.

In limited drilling at CVZ (7 holes for 3,500m), the

presence of strong sulphide mineralization and porphyry fragments in drill core provide geological

evidence for a blind porphyry deposit.

C3 Metals geologic modelling suggests this potential lies at depth

to the northwest of CVZ.

With the Drill Permit modification approved and the Authorization to Start

Activities now received, the Company is in the position to systematically drill test this interpretation.

permit area (blue).

The approved permit modification represents a 74% increase to the Drill Permit area

and allows for an additional 24 drill platforms and 53 holes.

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

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.
