C3 Metals Inc. reports exploration developments for copper-focused mineral projects in Peru and Jamaica. Company updates center on drilling and assay results at the 100%-owned Khaleesi copper project in southern Peru, where releases describe skarn- and porphyry-style copper, gold, silver and molybdenum mineralization, geophysical targets, soil geochemistry and diamond drill programs.
Recurring updates also cover activity at the 50%-owned Super Block project in Jamaica, project infrastructure and operating continuity, material agreements, governance matters, and operating and financial results. The company’s news flow is tied to exploration-stage project advancement, mineralized intercepts, permitting and operational risks common to mineral exploration.
C3 Metals (OTCQB: CUAUF) reported first-ever drill hole results at its 100%‑owned Khaleesi copper project in southern Peru on December 15, 2025. Drill hole KHZ5800-001 returned 269.0m at 0.30% Cu, including 60.4m at 0.41% Cu from 346.0m, and ended in mineralization at 626.1m. The hole also hit near-surface high-grade skarn (4.0m at 2.03% Cu) and a polymetallic epithermal vein (2.3m at 0.77% Cu, 0.495 g/t Au, 92.10 g/t Ag). Results confirm copper extends beneath shallow glacial till and intersect both skarn- and porphyry-style mineralization. Follow-up drilling and 3D geological modeling are planned to refine targets and test strike and depth extensions.
C3 Metals (OTCQB: CUAUF) reports its Jamaica team is safe after Hurricane Melissa made landfall on October 28, 2025.
The company sustained roof damage to core logging and storage facilities but confirmed no damage to drill rig, drill core, rock samples, or major equipment. Heavy winds and rain left multiple roads impassable, uprooted power poles causing no power to project areas, and damaged drill pads and access trails.
C3 Metals estimates 6–8 weeks to repair infrastructure before exploration resumes and has shifted near-term focus to providing food, water, power and debris-clearing assistance to local communities. Active programs paused include a 14-hole Super Block scout drill (7 of 14 holes complete; assays pending for 3 holes), Bellas Gate drilling (4 holes completed; 5 planned), and a 3DIP survey (46 of 70 sq km collected).
C3 Metals (OTCQB: CUAUF) has started a district-scale 3D induced-polarization (3DIP) survey at its 100% owned Bellas Gate copper-gold project in Jamaica.
The survey expands coverage from ~16 sq. km to ~70 sq. km, aims to image to 700m–1,000m depth, and is being carried out by Dias Geophysical with completion anticipated in December 2025. Results will be integrated with magnetic and geochemical data to design the 2026 drill program.
The project is subject to an earn-in with Freeport allowing Freeport to fund up to US$75 million to earn up to 75% interest. Historical drill intercepts include long, moderate-grade porphyry results (e.g., 390.7m @ 0.37% Cu, 0.19 g/t Au).
C3 Metals (OTCQB: CUAUF) has initiated its maiden drill program at the 100%-owned Khaleesi copper-gold project in Peru. The program consists of 14 diamond drill holes totaling 6,300 meters, designed to evaluate copper-gold-molybdenum skarn and porphyry prospects.
The company will deploy two drilling rigs: the first rig will execute 7 holes over 3,000m targeting skarn copper-gold mineralization with a significant soil anomaly averaging 1,260ppm copper. The second rig, scheduled for October 2025, will complete 7 holes over 3,300m targeting porphyry-style copper mineralization with soil anomalies averaging 950ppm copper.
The Khaleesi project is strategically located on the world-class Andahuaylas-Yauri Porphyry-Skarn belt, with the program fully funded alongside concurrent drilling at Super Block and Bellas Gate in Jamaica.
C3 Metals (OTCQB: CUAUF) has reported significant gold mineralization in its first four scout drill holes at the Super Block project in Jamaica, a 50% joint venture with Geophysx Jamaica Limited. The drilling program, located 1.8km from the past-producing Pennants Gold Mine, intersected broad zones of gold mineralization in all four holes.
Key highlights include intersections of 23.80m at 0.51 g/t Au and 10.30m at 1.23 g/t Au in hole SUP4025-001, with the highest grade of 2.48 g/t Au over 1.00m in hole SUP4025-003. The mineralization is associated with suspected adularia alteration and appears to be structurally controlled, low sulphidation epithermal style.
The company plans to continue testing high-priority targets along the 5km gold trend with an additional 10 scout holes through 2025, as part of a 2,500m Phase 1 drilling program.
C3 Metals (OTCQB: CUAUF) has contracted AK Drilling International to conduct a minimum 6,000-meter diamond core drilling program at its wholly-owned Khaleesi copper-gold project in Peru. The initial program comprises 14 drill holes designed to test coincident geochemical and geophysical anomalies.
Mobilization is scheduled for early September, with all necessary regulatory approvals secured. The company is currently preparing drill access trails, pads, and camp construction. The drilling will target two IP chargeability anomalies that converge at approximately 600m depth, coinciding with strong copper soil geochemical anomalies.
C3 Metals (OTCQB: CUAUF) has secured all necessary regulatory approvals to begin its maiden drilling program at the Khaleesi copper-gold project in Peru. The approvals include surface access agreements, environmental permits, and water use authorization. The company plans to commence a 6,000-metre diamond drill program in September 2025.
The Khaleesi project, spanning over 31,000 hectares, represents an undrilled copper-gold mineralized prospect in the Andahuaylas-Yauri Porphyry-Skarn belt. Recent geophysical surveys revealed significant anomalies coinciding with high-grade copper-molybdenum soil anomalies. Notable findings include a copper-zinc soil anomaly averaging 1,260ppm copper and a copper-molybdenum anomaly extending over 1,900m by 650m.
C3 Metals (OTCQB: CUAUF) has initiated exploration diamond drilling at its 100%-owned Bellas Gate Project in Jamaica, which spans 13,020 hectares. The project, subject to a recent earn-in agreement with Freeport-McMoRan that could earn up to 75% by funding US$75 million in exploration, targets 14 copper-gold porphyry prospects across an 18km strike extent.
The 2025 drilling program encompasses 9 diamond drill holes totaling 2,750m, including 4 holes (2,000m) targeting porphyry prospects and 5 holes (750m) testing volcanic redbed copper-silver mineralization. Previous drilling has yielded significant results, including intersections of 390.7m at 0.37% Cu and 0.19 g/t Au at Provost and 309.0m at 0.44% Cu and 0.33g/t Au at Connors.
[ "Significant earn-in agreement with Freeport-McMoRan worth up to US$75 million", "Previous drilling showed substantial copper-gold mineralization with impressive grades", "Large project scope with 14 porphyry prospects across 18km strike extent", "Strong soil sampling results in northwest project area with up to 0.16% copper over 50m zone" ]C3 Metals (OTCQB: CUAUF) has announced significant findings from geophysical surveys at its 100% owned Khaleesi copper-gold project in Peru. The surveys identified large-scale anomalies coinciding with high-grade copper-molybdenum soil anomalies measuring 1,900m by 650m and copper-zinc anomalies of 470m by 400m.
The company plans to commence a maiden 14-hole, 6,000m diamond drill program in Q3 2025. Key findings include magnetic survey confirmation of a large near-surface magnetic body, two discrete IP chargeability anomalies, and soil samples yielding up to 2.82% copper, 6.0 g/t gold, and 57.7 g/t silver. The project is strategically located within 45km of major copper mines Las Bambas and Constancia.
