C3 Metals Commences Maiden Drill Program

at Khaleesi Copper-Gold Project, Peru

Toronto, Ontario--(Newsfile Corp. - September 30, 2025) -

C3 Metals Inc.

(TSXV: CCCM) (OTCQB:

CUAUF) ("C3 Metals" or the "Company") is pleased to announce that it has commenced a 14-diamond

drill hole, 6,300m maiden drill program at its 100%-owned Khaleesi copper-gold project ("Khaleesi" or

"the Project").

This maiden drill program has been designed to evaluate copper-gold-molybdenum skarn

and porphyry prospects identified through geologic mapping, strong soil geochemistry and coincident

magnetic ("Mag") and Induced Polarization ("IP") chargeability highs (Figure 1).

Khaleesi is located on

the well-known, world-class Andahuaylas-Yauri Porphyry-Skarn belt (Figure 2).

The two IP chargeability anomalies

come together at approximately 600m depth.

Dan Symons, President and CEO, stated

, "We are very pleased to announce we have commenced the

first ever drill program at Khaleesi.

This maiden drill program was designed following a systematic

collection of important geologic, geochemical and geophysical data.

The results from exploration to

date have yielded all the ingredients we look for in a sizeable porphyry-skarn system, and Khaleesi is

located in a similar geologic setting as other major mines in this world-class copper producing district.

We plan to drill with two rigs — one on each of the skarn and porphyry prospects.

This is an exciting

time for the Company, as commencing the drill program at Khaleesi now gives us three projects with

drills turning: Khaleesi, Peru; Super Block, Jamaica; and Bellas Gate, Jamaica.

All programs are fully

funded, as we aim to maximize discovery potential for our shareholders."

Khaleesi Maiden Drill Program

A 14 hole, 6,300m drill program is planned, utilizing two drill rigs.

The first rig has commenced drilling and is testing a broad zone of skarn hosted copper-gold

mineralization with coincident geophysics anomalies.

Seven holes over 3,000m will target a skarn copper-gold zone with coincident Mag and IP

chargeability high anomalies and a coincident resistivity low anomaly that correlate with a

470m by 400m copper-zinc soil anomaly averaging 1,260ppm copper.

The second rig is scheduled to commence drilling during October 2025 and will target porphyry-

style copper mineralization mapped at surface.

Seven holes over 3,300m will target porphyry-style copper mineralization with coincident

Mag, IP chargeability and resistivity high anomalies that correlate with a 800m by 400m

copper-molybdenum in soil anomaly averaging 950ppm copper.

About the Khaleesi Project

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

and porphyry prospect located 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 2).

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.

Recent geophysical surveys identified large, coincident Mag and IP 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 3).

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 4).

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 5).

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.

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 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 5).

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.

Geophysical data supports the interpretation of the connection of these

zones beneath the till occurrence.

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 copper-gold mineralization.

Recently acquired Mag and IP provide further evidence for a potentially sizeable hydrothermal 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.

The Company has now commenced the first ever drill program at Khaleesi.
