C3 Metals Intersects 64.9 Metres at 3.45% Copper Equivalent, Including 23.3 Metres at 6.64% Copper Equivalent at its Khaleesi Project, Peru - Highest Grade Copper and Gold Mineralization Intersected to Date at Khaleesi

Toronto, Ontario--(Newsfile Corp. - November 2, 2026) - C3 Metals Inc. (TSXV: CCCM) (OTCQB: CUAUF) ("C3 Metals" or the "Company") is pleased to announce results of the highest-grade copper-gold-silver mineralization intersected to date at its 100%-owned Khaleesi copper project ("Khaleesi" or "the Project") in southern Peru. Drill hole KHZ5790-005 intersected a broad interval of intense chalcopyrite mineralization hosted within the main magnetite skarn body that is being defined through the current drill program (Table 1).

Khaleesi Drilling Highlights * Hole KHZ5790-005 drilled to test a magnetite and garnet skarn body within an area of limited previous drilling intersected 64.9 metres ("m") at 2.53% copper, 0.87 g/t gold, 11.6 g/t silver, 6 ppm molybdenum (3.45% CuEq) from approximately 337.6m downhole depth. * Includes high-grade interval of 23.3m at 4.75% copper, 1.84 g/t gold, 20.4 g/t silver, 5 ppm molybdenum (6.64% CuEq) from 352.1m downhole depth. * Copper mineralization is hosted in skarn lithologies with intense chalcopyrite mineralization occurring as disseminations, cm-scale veins and as massive infill (Figure 1). * Demonstrates potential for high-grade mineralization within the multi-kilometre skarn system identified at Khaleesi to date. * Follow up drilling to test geometry, continuity and potential extent of the high-grade copper-gold-silver mineralization is in progress. Dan Symons, President and CEO, stated, "These are the highest copper grades we have encountered to date at Khaleesi and represent a very encouraging development for this emerging copper-gold discovery. An intercept of 64.9m grading 3.45% copper equivalent, including 23.3m at 6.64% copper equivalent, demonstrates the potential for significant higher-grade mineralization within the broader system. We are still at an early stage in understanding the geometry and potential extent of this higher-grade mineralization. We are systematically stepping out from this intercept in multiple directions to test its continuity and determine its potential scale. We look forward to reporting additional results as this work progresses."
