C3 Metals completes 6,300 m drill program at Khaleesi

Mr. Dan Symons reports C3 METALS COMMENCES MAIDEN DRILL PROGRAM AT KHALEESI COPPER-GOLD PROJECT, PERU C3 Metals Inc. has commenced a 14-diamond-drill-hole, 6,300-metre maiden drill program at its 100-per-cent-owned Khaleesi copper-gold 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. Khaleesi is located on the well-known, world-class Andahuaylas-Yauri porphyry-skarn belt. Dan Symons, president and chief executive officer, 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, 6,300-metre 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 3,000 m 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 470-metre-by-400-metre copper-zinc soil anomaly averaging 1,260 ppm (parts per million) 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 3,300 m will target porphyry-style copper mineralization with coincident Mag, IP chargeability and resistivity high anomalies that correlate with a 800 m by 400 m copper-molybdenum in soil anomaly averaging 950 ppm 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 45 km 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. 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 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. Recent geophysical surveys identified large, coincident Mag and IP anomalies at Khaleesi (see press release dated Aug. 6, 2025). These geophysical anomalies coincide with a recently defined high-grade copper-molybdenum-in-soil anomaly measuring 1,900 m by up to 650 m and a high-grade copper-zinc in soil anomaly measuring 470 m by 400 m (see press release dated Feb. 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. 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 approximately 600 vertical metres. Soil geochemical sampling defined a 1,900 m long by up to 650 m wide copper-molybdenum soil anomaly, with two priority zones averaging 950 ppm copper and 650 ppm copper in soils. For reference, copper in soils at or above 300 ppm is considered anomalous and is a high priority for further exploration. Skarn zone -- IP chargeability and coincident resistivity low anomaly correlates with a 470 m by 400 m copper-zinc soil anomaly averaging 1,260 ppm 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 800 m by 400 m 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-square-kilometre porphyry, skarn and epithermal alteration zone. Outcrop samples assayed up to 2.82 per cent copper, 6.0 g/t gold, 57.7 g/t silver and 403 ppm molybdenum (see press releases dated Oct. 22, 2024, and Jan. 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 470 m by 400 m wide copper-zinc-in-soil anomaly, with soils averaging 1,260 ppm copper and 450 ppm zinc. Grid soils also defined a significant copper-molybdenum anomaly, which extends for over 1,900 m by up to 650 m; two discrete zones average 950 ppm and 650 ppm copper, respectively. Soil sampling also covered a 1.3 square km area with a thin glacial till cover, varying from less than one m to 15 m in thickness. Glacial till appears to conceal interpreted extensions of the skarn and porphyry mineralized zones. Geophysical data support the interpretation of the connection of these zones beneath the till occurrence. Initial mapping and sampling at Khaleesi defined an alteration footprint spanning 1,500 m by 1,000 m. 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. 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. 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 15 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 at 0.5 per cent copper and 0.2 g/t (gram per tonne) 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., 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).
