C3 Metals Identifies Multiple Coincident

Magnetic and Gravity Anomalies to Drill at Its

Khaleesi Project, Peru

Toronto, Ontario--(Newsfile Corp. - September 17, 2026) -

C3 Metals Inc.

(TSXV: CCCM) (OTCQB:

CUAUF) ("C3 Metals" or the "Company") is pleased to announce that its geophysics contractor has

completed the new drone magnetic and gravity surveys at its 100%-owned Khaleesi copper project

("Khaleesi" or "the Project") in southern Peru (see press release dated June 24, 2026).

High-resolution unmanned aerial vehicle (UAV) drone magnetometer and gravity geophysical surveys

were initially planned over 900 hectares. Due to the success of the new surveys in identifying multiple

coincident magnetic and gravity anomalies, the Company has expanded the surveys by over 65% to

1,500 hectares.

Figure 1 shows the initial 900-hectare survey results, and Figure 4 shows the additional

600 hectares where the expanded surveys are underway.

Dan Symons, President and CEO, stated

, "To date, the combination of magnetics and gravity has

proven extremely valuable at targeting copper mineralization hosted in magnetite skarns that sit below

a thin layer of glacial till cover.

We embarked on these additional geophysics programs specifically to

identify other potential magnetite skarns over a much broader area.

This broader survey area

generally corresponds to a modified environmental drill permit that we anticipate obtaining during Q4.

This new data shows impressive, sizeable anomalies.

Drilling is continuing to expand on the known

mineralized zone at Khaleesi with a goal of beginning to drill test newly identified targets in Q4."

Khaleesi Geophysical Survey Highlights

A new geophysical survey identified coincident and large-scale magnetic and gravity anomalies

beneath the glacial till cover at Khaleesi.

Large anomalies are present where recent drilling

intersected broad zones of intrusive and skarn hosted copper-gold-molybdenum mineralization

(see press releases dated February 26, 2026, April 29, 2026, June 26, 2026 and September 15,

2026).

A drone magnetics survey comprised 40 line-kilometres with 50m line spacings.

A gravity survey

comprised 900 hectares with data collected at 100m spacings.

Results include:

Multiple northeast-southwest trending coincident magnetic and gravity anomalies that are

coincident with the intrusive complex - Ferrobamba Formation contact zone that hosts the

copper-gold-molybdenum mineralization (Figure 1).

The main skarn zone at Khaleesi correlates well with a strong coincident magnetic and

gravity anomaly that measures 500m by 600m.

The anomaly extends to the northeast

(Figures 1 and 2).

A second and potentially larger magnetic and gravity anomaly is partially defined

approximately 2km northeast of the Khaleesi main skarn.

Recent geological mapping

confirms a large-scale magnetite skarn in the area (see Figures 1, 2, and 3).

The drone magnetic and gravity surveys have been expanded and are currently

underway in the northeast project area with the goal of capturing the extent of this new,

large-scale coincident magnetic and gravity anomaly.

Geological mapping confirms the

presence of magnetite skarn associated with the anomaly (Figures 3 and 4).

Cross sections through the 3D magnetic inversion model A-A' and the gravity inversion

model B-B' demonstrates the two large scale and deep-rooted magnetic anomalies,

including the new prospect to the northeast (Figure 2).

Multiple new coincident magnetic and gravity anomalies have been identified to the

southwest, south and southeast.

southwest trend and additional new anomalies to the south. (Right) Gravity image showing multiple

gravity anomalies along the same northeast-southwest trend and additional new anomalies to the south.

Survey Details

The recently completed drone magnetic and gravity surveys have proven to be an excellent exploration

tool to identify blind skarn targets in the project area, which is predominantly covered by a thin layer of

glacial till.

The data has provided high-resolution magnetic and gravity information that has been inverted

to produce 3D block models for each dataset.

The block models show geological and structural patterns

beneath the 5-50m thick glacial till cover. The anomalies predominantly follow a northeast-southwest

trend.

This trend is similarly identified and modeled using existing drill data that define zones of copper-

gold-molybdenum mineralization.

Drill core magnetic susceptibility and specific gravity measurements

confirm the model, increasing confidence of the geophysical datasets.

Figure 2. (Top) Cross section through the 3D magnetic inversion model A-A' shows the two large scale

and deep-rooted magnetic anomalies at the main Khaleesi drill area and a new prospect approximately

2km to the northeast. (Bottom) Cross section through the 3D gravity inversion model B-B' shows the two

large scale and deep-rooted gravity anomalies at main Khaleesi drill area and a new prospect

approximately 2km to the northeast.

The 3D magnetic and gravity inversion models show large scale coincident magnetic and gravity

anomalies at Khaleesi and at a new prospect 2km to the northeast.

The new prospect has outcropping

skarn that has been mapped over a 200m by 150m area (Figure 3).

The skarn is characterized by

massive magnetite replacing dolomite of the Ferrobamba Formation.

The partially defined magnetic

anomaly near to the new prospect appears to be larger or of similar scale to the magnetic anomaly

covering the main Khaleesi skarn zone.

This warranted extending the geophysical surveys to cover the

new prospect area (Figure 4).

Geologic mapping has confirmed the presence of magnetite skarn associated with a new, large-scale

coincident magnetic and gravity high.

Next Steps

Drilling at Khaleesi has intersected broad zones of intrusive and skarn hosted copper-gold-molybdenum

mineralization that remains open to the north, east and west (see press releases dated February 26,

2026, April 29, 2026, June 26, 2026 and September 15, 2026).

Magnetic and gravity datasets have increased targeting confidence by enabling the Company to focus

future drilling on testing the northeast-southwest trending mineralized skarn and intrusive complex.

This

could potentially extend 2km from the original Khaleesi discovery to the new prospect.

An amended

environmental drill permit (modified DIA) is anticipated in Q4 (Figure 4).

Additionally, surface mapping and soil sampling continues across the broader Khaleesi project area and

is expected to be completed in Q4.

The Company continues drill testing additional skarn targets and

expanding on the known skarn and diorite hosted mineralization.

Geometallurgical work is also being

planned to identify extraction methods and recoveries for copper, gold, silver, molybdenum and iron.

The Company looks forward to reporting additional geophysical survey and assay results as they

become available.

About the Khaleesi Project

The Khaleesi project is located in the Andahuaylas-Yauri Belt in southeastern Peru, home to large

copper skarn and porphyry deposits and operating mines such as Las Bambas (MMG), Constancia

(Hudbay Minerals), Antapaccay (Glencore), and others (Figure 5).

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 along the

28km iron-skarn belt that 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.

The Khaleesi project is situated along a highly favorable limestone-intrusive rock contact zone that

bisects the tenement area and trends north-northeasterly.

The limestone rock unit is part of the highly

receptive Ferrobama Formation, and the intrusive rock comprises the well-known Andahuaylas-Yauri

Batholith. At this contact zone is a multiphase intrusive complex that also appears to trend northeast-

southwest, that follows and exploits the contact zone, which is mostly covered by a thin layer of glacial till.
