C3 Metals Obtains All Regulatory Approvals

Required for Maiden Drill Program at Khaleesi

Copper-Gold Project, Peru

Toronto, Ontario--(Newsfile Corp. - August 18, 2025) -

C3 Metals Inc.

(TSXV: CCCM) (OTCQB:

CUAUF) ("C3 Metals" or the "Company") is pleased to announce that it has obtained all regulatory

approvals required to commence exploration drilling at its 100%-owned Khaleesi copper-gold project

("Khaleesi" or "the Project").

Regulatory approvals include:

Surface Access and Drilling Agreements with the Cancahuani community (Social license);

Declaración de Impacto Ambiental or DIA (Environmental permit);

Autorización de Inicio de Actividades de Exploración (Authorization to Start Exploration Activities);

and

Autorización de Uso de Agua (Authorization of Use of Water).

Dan Symons, President and CEO, stated

, "Khaleesi has long been a top geological target in our

portfolio. We are very pleased that all necessary approvals are in hand for our first drill campaign at

this exciting property.

Concurrent with the drill permitting process, we generated a substantial amount

of technical data through geologic mapping, geochemical and geophysical programs.

It's quite

remarkable that within such a well-known, world-class copper producing district we will be the first

company to ever conduct exploration drilling on this highly prospective property.

We anticipate we will

commence an initial 6,000-metre diamond drill program in September 2025."

Khaleesi represents a rare opportunity to explore an undrilled copper-gold mineralized skarn, epithermal

and porphyry prospect on the well-known, world-class Andahuaylas-Yauri Porphyry-Skarn belt.

The

Company has strategically amalgamated a significant mineral concession package of over 31,000

hectares within 45km of the large Las Bambas (MMG) and Constancia (Hudbay Minerals) copper

mines.

Several major and intermediate mining companies hold mineral concessions surrounding C3

Metals' package and in the district (Figure 1).

Khaleesi is located 8km west of the Company's Jasperoide Project, where the Company confirmed 13

skarn prospects along a 28km iron-skarn belt.

Montana de Cobre ("MCZ") is the only skarn the

Company has systematically drill tested to date, yielding

a near surface Measured and Indicated

Mineral Resource of 51.9 million tonnes at 0.50% total copper and 0.20 g/t gold for 569.1 million

pounds of copper and 326,800 ounces of gold.

[1]

Recent geophysical surveys identified large, coincident magnetic ("Mag"), Induced Polarization ("IP")

and MagnetoTelluric ("MT") anomalies at Khaleesi (see press release dated August 6, 2025).

These

geophysical anomalies coincide with a recently defined high-grade copper-molybdenum in soil anomaly

measuring 1,900m by up to 650m and a high-grade copper-zinc in soil anomaly measuring 470m by

400m (see press release dated February 19, 2025).

Highlights of the Khaleesi Exploration Program to Date

The Mag survey confirms a

large, near-surface magnetic body

that separates into two bodies at

depth.

This Mag anomaly is coincident with IP chargeability and resistivity anomalies and areas

with high copper geochemistry in soils (Figure 2).

The IP survey

defined two discrete near-surface IP chargeability anomalies with coincident

resistivity anomalies

, which extend to the maximum depth for this IP survey reliability of ~600

vertical metres (Figure 3).

Soil geochemical sampling defined a

1,900m long by up to 650m wide copper-molybdenum

soil anomaly

with two priority zones averaging 950ppm copper and 650ppm copper in

soils

(Figure 4).

For reference, copper in soils at or above 300ppm is considered anomalous and

is a high priority for further exploration.

Skarn Zone - IP chargeability and coincident resistivity low anomaly correlates with a

470m

by 400m copper-zinc soil anomaly averaging 1,260ppm copper

that is open along-

strike to the north, south and to depth.

South Zone - IP chargeability and coincident resistivity high anomaly correlate with a

800m

by 400m copper-molybdenum in soil anomaly averaging 950 ppm copper

where

porphyry-style copper mineralization has been mapped at surface.

MT/AMT survey shows a large conductive body coincident with the IP and magnetic anomalies,

which also extends to depth.

Field mapping confirmed a 3.3 sq km porphyry, skarn and epithermal alteration zone.

Outcrop samples assayed up to

2.82% copper, 6.0 g/t gold, 57.7 g/t silver and 403 ppm

molybdenum

(see press releases dated October 22, 2024 and January 8, 2025).

Coincident geophysical anomalies, along with the recently defined copper-in-soil geochemical

anomalies, provide further support for the interpretation of a potentially significant porphyry, skarn

and epithermal copper-gold hydrothermal system at Khaleesi.

Grid soils defined a 470m by 400m wide copper-zinc in soil anomaly, with soils averaging 1,260ppm

copper and 450ppm zinc.

Grid soils also defined a significant copper-molybdenum anomaly, which

extends for over 1,900m by up to 650m; two discrete zones average 950ppm and 650ppm copper,

respectively (Figure 4).

Soil sampling also covered a 1.3 sq km area with a thin glacial till cover, varying

from less than 1m to 15m in thickness.

Glacial till appears to conceal interpreted extensions of the skarn

and porphyry mineralized zones.

The geophysical data supports the interpretation of the connection of

these zones beneath the till occurrence.

Next Steps

Initial mapping and sampling at Khaleesi defined an alteration footprint spanning 1,500m by 1,000m.

Subsequent soil sampling defined multiple large scale and coherent copper-in-soil anomalies located

over a significant zone of mapped porphyry-skarn-epithermal styles of mineralization.

Recently acquired

Mag, IP and MT data, provide further evidence for a sizeable system that appears to connect in the

central project area beneath the glacial till occurrence.

Based on all data collected to date, the Khaleesi

project is ranked highest priority for drill testing.

Khaleesi has never been drill tested historically or by C3

Metals.

The Company has obtained all regulatory approvals required to commence drilling.

An initial 14-hole,

6,000-metre diamond drill program has been designed.

The Company anticipates commencing this

program in September 2025.

The Company is also actively exploring in Jamaica where it has identified 16

porphyry, 40 epithermal and multiple volcanic redbed copper prospects over a 30km strike extent.

The

Company holds a 100% interest in 17,855 hectares of exploration licenses, of which Freeport-McMoRan

Exploration Corporation, a wholly-owned affiliate of Freeport-McMoRan Inc. (NYSE: FCX), has the
