C3 Metals Wholly Owned Subsidiary, Molino Azul S.A.C.

Executes Agreement with Cancahuani Community to Provide Surface Access Rights at Khaleesi Copper-Gold Porphyry-Skarn Project in Peru

Toronto, August 13, 2024 - C3 Metals Inc. (TSXV: CCCM) (OTCQB: CUAUF) ("C3 Metals" or the "Company") is pleased to announce that its wholly owned subsidiary, Molino Azul S.A.C, has executed a surface access rights agreement with the Cancahuani community at its Khaleesi porphyry and skarn copper-gold project in Southern Peru. The Khaleesi project is an outcropping, mineralized, undrilled copper-gold skarn and porphyry prospect. The Las Bambas and Constancia copper mines are located less than 45km away and within the same district, comprising large-scale porphyry-skarn complexes with similar geology and surface expression to that seen at Khaleesi. Surface access has been the critical path item for the Declaration of Environmental Impact ("DIA" or "Drill permit") to proceed. The Company has already completed the CIRA process, which determined the nonexistence of archeological remains in the Khaleesi project area.

Dan Symons, President and CEO, stated, "We have been working diligently for multiple years to foster a strong relationship built upon trust and mutual respect with the Cancahuani community. Surface access has been the critical path item required for us to move the Khaleesi project forward. Khaleesi is located on the western side of our 300 sq. km mineral concession package in Southern Peru approximately 38km east of the operating Las Bambas mine and 43km northwest of the Constancia and Pampacancha mines. First pass field work has identified high-grade copper-gold mineralization in outcropping porphyry, skarn and polymetallic epithermal veins at Khaleesi. The Khaleesi porphyry, skarn, and epithermal alteration system has been mapped at surface over a 1.5km by 1.0km area. Due to its proximity to and similar geologic setting as other large-scale copper mines in the district, it has always been one of the most prospective geological prospects in our portfolio. With this critical path agreement now in place and the remainder of the permitting process being prescriptive, we believe this agreement provides us significant optionality within our portfolio and allows us to explore strategic options more productively on how to best move our exploration portfolio forward in both Peru and Jamaica."

The Jasperoide and Khaleesi projects are located in the prolific Andahuaylas-Yauri Porphyry-Skarn belt of Southern Peru. Mineralization is hosted in a similar geological setting to the nearby major mining operations at Las Bambas (MMG), Constancia and Pampacancha (Hudbay) and Antapaccay (Glencore). C3 Metals, through its subsidiaries, holds a 100% interest in approximately 300 sq. km (30,000 hectares) of highly prospective copper-gold terrain (Figure 1).

C3 Metals first entered Southern Peru through the merger with the private company, Latin American Resource Group in 2020, gaining 57 sq. km in this recognized world-class copper belt. The Company then expanded its mineral concession package to its current 300 sq. km over the next three years. A main driver of this expansion was to gain exposure to the Khaleesi project area.

Khaleesi is located approximately 8km west of a 28km magnetite skarn belt where 13 skarn prospects have been identified. The first of these 13 skarns that C3 Metals systematically drill tested was Montana de Cobre, which yielded a maiden Measured and Indicated Mineral Resource of 51.9 million tonnes at 0.50% total copper and 0.20% gold for 569.1 million pounds of copper and 326,800 ounces of gold¹.

Khaleesi sits on a parallel porphyry and skarn belt approximately 8km to the west of Montana de Cobre. Khaleesi hosts outcropping skarn and porphyry style copper-gold mineralization with proximal high-grade polymetallic epithermal veins (Figures 2, 3 and 4). The Company is not aware of any previous exploration drilling at Khaleesi - it is a new discovery.

Next Steps

C3 Metals has identified over 15 skarn and multiple porphyry prospects within its 300 sq. km mineral concession package in Peru. The porphyry, skarn, epithermal mineralized system at Khaleesi is the highest priority of these prospects due to its high-grade copper and gold potential that outcrops at surface.

C3 Metals has previously collected magnetic geophysical data over the eastern Khaleesi project area, which shows a large magnetic anomaly coincident with the skarn- and porphyry-style copper-gold mineralization. With the surface access agreement now in place, the Company will proceed with collecting soil geochemical data and conducting an aggressive surface mapping and rock sampling program concurrent with completing the Drill permit process.

Dan Symons continued: "We anticipate drilling at Khaleesi could commence as early as 2025. Now that an agreement has been reached with the community, the remainder of the permitting process becomes prescriptive. We plan to commence the necessary field work to be drill-ready on receipt of all necessary approvals. The Peruvian government has recently done an outstanding job with moving permits for both exploration and expansion of existing operations through its system at a much more accelerated pace. With the support of the Cancahuani community, we believe we are well positioned for the remainder of the process. We are excited to get boots on the ground to complete detailed mapping and sampling before drilling."
