C3 Metals Intersects 101.9 Metres at 0.38% and 70.9 Metres at 0.62% Copper Equivalent at its Khaleesi Project, Peru - Mineralization Extended East

Toronto, Ontario--(Newsfile Corp. - October 27, 2026) - C3 Metals Inc. (TSXV: CCCM) (OTCQB: CUAUF) ("C3 Metals" or the "Company") is pleased to announce results from two additional holes drilled at its 100%-owned Khaleesi copper project ("Khaleesi" or "the Project") in southern Peru. Drilling has further extended mineralization 200 metres ("m") eastward along section line KHZ5950 (Figure 1), with drill holes KHZ5960-004 and KHZ5960-005 intersecting broad intervals of near-surface copper mineralization. Drill hole KHZ5960-004 also intersecteed a higher copper grade interval at depth (Table 1).

Khaleesi Highlights * KHZ5960-004 intersected pervasive porphyry and skarn-style alteration with primary and secondary copper mineralization. A near surface 101.9m zone of mineralized gabbroic diorite reported 0.31% copper, 0.025 g/t gold, 1.06 g/t silver, 64 ppm molybdenum (0.38% CuEq) from 28.4m downhole depth. This was followed downhole by a 70.9m intercept of magnetite and pyroxene + garnet skarn that reported 0.53% copper, 0.036 g/t gold, 0.88 g/t silver, 112ppm molybdenum (0.62% CuEq) from 376.6m downhole depth. * KHZ5960-005 similarly intersected near surface primary and secondary copper mineralization but did not intersect the magnetite skarn at depth. A near surface 81.3m zone of mineralized diorite reported 0.27% copper, 0.021 g/t gold, 0.84 g/t silver, 54 ppm molybdenum (0.33% CuEq) from 36.7m downhole depth. * Mineralization remains open in multiple directions. Dan Symons, President and CEO, stated, "Drilling at Khaleesi continues to demonstrate the broad distribution of copper mineralization. These two recent drill holes intersected significant intervals of near-surface mineralization, with one hole also intersecting higher-grade copper-bearing skarn at depth. As we continue to advance our understanding of this large mineralized system, our exploration strategy remains focused on identifying and testing prospective areas across the project. We recently completed magnetic and gravity surveys over 1,500 hectares. Also, a 3DIP survey is currently underway. Together, these geophysical datasets will provide important additional information to help refine our geological model and prioritize drill targets over an expanded project area."
