C3 Metals Sampling Program at Khaleesi Copper-Gold Project in Peru Returns up to 2.82% Copper, 6.0 g/t Gold, 57.7 g/t Silver and 284 ppm Molybdenum

Toronto, Ontario--(Newsfile Corp. - October 22, 2024) - C3 Metals Inc. (TSXV: CCCM) (OTCQB: CUAUF) ("C3 Metals" or the "Company") is pleased to announce results from partially completed surface mapping and sampling on its Khaleesi copper-gold project in the prolific Andahuaylas-Yauri Porphyry-Skarn belt of Southern Peru. The Khaleesi project is an outcropping, mineralized, undrilled copper-gold skarn and porphyry prospect.

The Company's recent "boots on the ground" surface mapping and sampling program has successfully delineated compelling skarn, porphyry and epithermal vein targets. Rock chip samples returned up to 2.82% copper, 6.0 g/t gold, 57.7 g/t silver and 284 ppm molybdenum.

Dan Symons, President and CEO, stated, "Khalessi is host to a large area of outcropping copper-gold mineralized skarn and epithermal veins. Importantly, the project displays several vectors indicative of a potential copper-gold porphyry system. It is incredible that in such a well-known, world-class copper producing district, we have been able to identify an undrilled project like Khaleesi. We plan to complete mapping and rock sampling, run a soil geochemical survey, and ground magnetic and IP surveys in advance of a maiden drilling program at Khalessi."

The Las Bambas and Constancia copper mines are located less than 45km away from Khaleesi and within the same district (Figure 1), comprising large-scale porphyry-skarn complexes with similar geology and surface expression to that seen at Khaleesi. Khaleesi sits on a northwest trending porphyry and skarn belt that is located approximately 8km to the west of the Company's Jasperoide project (Figure 2) where the Company has identified 13 skarn prospects. The first of these 13 skarns to be 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 g/t gold for 569.1 million pounds of copper and 326,800 ounces of gold.1

Highlights of Recent Mapping and Sampling Program at Khaleesi

Stephen Hughes, VP Exploration commented: "Initial exploration data collected at Khaleesi confirms the right ingredients for a classic porphyry-skarn system similar to other nearby major copper-gold deposits along the Andahuaylas-Yauri Porphyry-Skarn belt of Southern Peru. To date, copper-gold mineralization has been primarily confirmed in the outcropping skarn and epithermal zones, but the proximal marbleized limestone is very important geologically. We have identified sheeted and stockwork quartz veins in the marbleized limestone that appears to be porphyry related, with rock chips assaying elevated levels of molybdenum and arsenic. Given the total alteration footprint at Khalessi is over 1km by 1km, the potential for a system of meaningful scale appears to be high. The planned program will provide sufficient data to drill test this potential."

Khaleesi and Jasperoide are located along the prolific Andahuaylas-Yauri Porphyry-Skarn belt of Southern Peru. Jasperoide is located along a magnetite skarn belt that contains multiple skarn bodies, including Montana de Cobre Zone ("MCZ") skarn deposit. MCZ is the first of 13 identified magnetite skarns that the Company systematically drill tested, yielding a maiden 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

Mineralization at Khaleesi is in a similar geological setting to the nearby major mining operations at Las Bambas (MMG), Constancia and Pampacancha (Hudbay) and Antapaccay (Glencore). The Ferrobamba Formation is an important host for copper-gold mineralization due to its highly reactive nature to hydrothermal fluids.

Recent mapping and sampling at Khaleesi have identified outcropping skarn, epithermal and porphyry style alteration with associated copper-gold mineralization (Figure 3). The Khaleesi skarn is zoned, with a prograde garnet-diopside skarn transitioning to magnetite-rich retrograde skarn. Rock samples (Figure 4) collected from mineralized outcrops has yielded up to 2.82% copper, 6.0g/t gold, 57.7 g/t silver and 284ppm molybdenum. Immediately west of the skarn is marbleized limestone of the Ferrobamba Formation, locally cut by sheeted and stockwork quartz veins (Figure 4). Rock chip samples of marble cut by quartz veins assayed low in copper geochemistry but yielded up to 2.55g/t gold, 264ppm arsenic and 19.3ppm molybdenum. The copper-gold-molybdenum geochemical signature in rock chips supports the interpretation of a porphyry system at Khaleesi.

Next Steps

The undrilled Khaleesi copper-gold porphyry project hosts outcropping skarn and epithermal mineralization. It is a high priority target due to the size of the footprint and its proximity to major producing mines.

With a surface access agreement in place with the Cancahuani Community (see press release dated August 13, 2024), the Company plans to complete surface mapping and sampling over the 1,800Ha Khaleesi project area. Currently, mapping and sampling is approximately 50% complete. The Company is also planning to undertake soil sampling, Induced Polarization and ground magnetic geophysical surveys over the main project area. These programs should provide essential data prior to drilling and will run concurrently with drill permitting, which is advancing and considered prescriptive now that a surface access agreement is in place.
