C3 METALS IDENTIFIES MULTIPLE COINCIDENT MAGNETIC AND GRAVITY ANOMALIES TO DRILL AT ITS KHALEESI PROJECT, PERU

C3 Metals Inc.'s geophysics contractor has completed the new drone magnetic and gravity surveys at its 100-per-cent-owned Khaleesi copper 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 per cent to 1,500 hectares.

Dan Symons, president and chief executive officer, 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 Feb. 26, 2026, April 29, 2026, June 26, 2026, and Sept. 15, 2026).
• A drone magnetics survey comprised 40 line kilometres with 50-metre line spacings. A gravity survey comprised 900 hectares with data collected at 100 m 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.
  • The main skarn zone at Khaleesi correlates well with a strong coincident magnetic and gravity anomaly that measures 500 m by 600 m. The anomaly extends to the northeast.
  • A second and potentially larger magnetic and gravity anomaly is partially defined approximately two kilometres northeast of the Khaleesi main skarn. Recent geological mapping confirms a large-scale magnetite skarn in the area.
    • The drone magnetic and gravity surveys have been expanded and are currently under way 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.
• Cross sections through the 3-D 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.
• Multiple new coincident magnetic and gravity anomalies have been identified to the southwest, south and southeast.

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 have provided high-resolution magnetic and gravity information that has been inverted to produce 3-D block models for each data set. The block models show geological and structural patterns beneath the five to 50 m thick glacial till cover. The anomalies predominantly follow a northeast-southwest trend. This trend is similarly identified and modelled 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 data sets.

The 3-D magnetic and gravity inversion models show large scale coincident magnetic and gravity anomalies at Khaleesi and at a new prospect two km to the northeast. The new prospect has outcropping skarn that has been mapped over a 200 m by 150 m area. 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.

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 Feb. 26, 2026, April 29, 2026, June 26, 2026, and Sept. 15, 2026).

Magnetic and gravity data sets 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 two km from the original Khaleesi discovery to the new prospect. An amended environmental drill permit (modified DIA) is anticipated in Q4.

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.

Khaleesi is located eight km west of the company's Jasperoide project, where the company confirmed 13 skarn prospects along a 28 km iron-skarn belt. Montana de Cobre (MCZ) is the only skarn along the 28 km 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 per cent 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.

About C3 Metals Inc.

C3 Metals 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 holds approximately 31,000 hectares located in the prolific high-grade Andahuaylas-Yauri porphyry-skarn belt of southern Peru, which contain the company's Jasperoide and Khaleesi projects. 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). At Jasperoide, the company has identified over 13 skarn prospects and an outcropping porphyry system over two parallel 28 km belts. The company has published a maiden resource estimate on the first of these skarn targets, which contained measured and indicated resources of 52 Mt (million tonnes) at 0.5 per cent copper and 0.2 g/t gold. The company is also actively exploring in Jamaica where it has identified 16 porphyry, 40 epithermal and multiple volcanic redbed copper prospects over a 30 km strike extent. The company holds a 100-per-cent interest in 17,855 hectares of exploration licences, of which Freeport-McMoRan Exploration Corp., a wholly owned affiliate of Freeport-McMoRan Inc. (New York Stock Exchange: FCX), has the option on 13,020 hectares to earn up to a 75-per-cent interest by funding up to $75-million (U.S.) of exploration and project related expenditures. The company also holds a 50-per-cent interest in 9,870 hectares in a joint venture with Geophsyx Jamaica Ltd., the largest mineral tenure holder in the country. Barrick Mining Corp. announced on May 1, 2024, that it had entered into an earn-in agreement with Geophysx Jamaica Ltd. on approximately 400,000 hectares of exploration licences, several of which surround C3 Metals' mineral concessions. 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).
