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 (CUAUF) extended copper mineralization 200 metres eastward with two additional drill holes at its wholly owned Khaleesi project in Peru. Hole KHZ5960-004 intersected 101.9 metres at 0.38% copper equivalent from 28.4 metres downhole and 70.9 metres at 0.62% from 376.6 metres. Copper equivalent combines copper and other metals into a copper-based grade. Hole KHZ5960-005 returned 81.3 metres at 0.33% copper equivalent from 36.7 metres, but did not intersect the deeper magnetite skarn, a mineralized rock type. These intervals are downhole lengths; true thicknesses remain undetermined.
Mineralization remains open in multiple directions. Magnetic and gravity surveys covering 1,500 hectares are complete, with data processing underway. A three-dimensional induced-polarization survey, which measures electrical responses underground, is 65% complete. C3 Metals expects completion during Q4 2026 and plans to use the combined data to refine drill targets.
C3 Metals (CUAUF) reports completion and expansion of drone magnetic and gravity surveys at its 100%-owned Khaleesi copper project in southern Peru after identifying multiple coincident anomalies.
The high-resolution UAV surveys were enlarged by over 65% from 900 to 1,500 hectares and now cover a northeast-southwest trend along the intrusive–Ferrobamba Formation contact that hosts copper-gold-molybdenum mineralization. A strong coincident magnetic and gravity anomaly of about 500m by 600m correlates with the main Khaleesi skarn zone, while a second, partially defined coincident anomaly lies approximately 2km to the northeast, where mapping shows outcropping magnetite skarn over roughly 200m by 150m. The program includes 40 line-kilometres of magnetics on 50m spacings and 900 hectares of gravity on 100m spacings. Drilling continues at Khaleesi, with the company anticipating a modified environmental drill permit in Q4 to begin testing newly identified targets.
C3 Metals (CUAUF) reported three new drill holes from its 100%-owned Khaleesi copper project in southern Peru, highlighted by broad copper-equivalent intercepts that extend skarn and intrusive mineralization to about 500m vertical depth and over 500m east‑west.
Hole KHZ5825-004 cut 119.5m grading 0.24% Cu, 0.035 g/t Au, 0.79 g/t Ag and 47 ppm Mo (0.30% CuEq) from 48.4m, and a separate 164.6m interval grading 0.28% Cu, 0.028 g/t Au, 0.93 g/t Ag and 51 ppm Mo (0.35% CuEq) from 304.5m. A shorter 55.6m zone at 0.18% Cu (0.23% CuEq) was also reported. Hole KHZ5860-001 returned 10.7m at 0.25% Cu and 0.271 g/t Au (0.53% CuEq), while KHZ5860-002 returned no significant assays.
About 15,100m of drilling in 33 holes has outlined a large east‑dipping skarn body that remains open, supported by new magnetic and gravity survey data and with 3DIP geophysics and further drilling planned for Q4.
C3 Metals (OTCQB: CUAUF) has completed a large-scale 3D induced polarization (3DIP) geophysical survey over its 100%-owned Bellas Gate copper-gold project in Jamaica, covering approximately 82.5 km² across two northwest–southeast trending porphyry belts previously intersected by drilling.
The 3DIP work, including 167 line‑km of receiver and 158 line‑km of transmitter coverage to ~1,000m depth, defined multiple deep-rooted chargeability anomalies coincident with surface porphyry-style alteration and mineralization, notably at the Provost, Kola and Lucky Valley prospects. According to C3 Metals, two independent inversion models show strong correlation between chargeability, magnetic data and known porphyry centres.
The company has designed an 11‑hole, 10,800m diamond drill program to test the highest-priority anomalies, anticipated to start in October 2026 and finish by April 2027. C3 Metals also reiterates its earn‑in agreement allowing Freeport-McMoRan Exploration to earn up to 75% in Bellas Gate by funding up to US$75 million in exploration and project expenditures.
C3 Metals (OTCQB: CUAUF) reported new drill results from 10 holes at the 100%-owned Khaleesi copper project in Peru, extending mineralization 400m and 1,000m southwest of the main skarn body.
Key intercepts include 67.6m at 0.51% CuEq, 60.9m at 0.55% CuEq and 4.2m at 3.16% CuEq. Additional long intervals of skarn and intrusive-hosted copper under glacial cover were also cut. About 13,600m of drilling in 31 holes is complete, with geophysical surveys planned mid‑June to September 2026 and one rig continuing to test high-priority targets.
C3 Metals (OTCQB: CUAUF) reported assays from 11 additional holes at the 100%‑owned Khaleesi copper project, Peru. Key results include 148.05m at 0.42% CuEq (0.34% Cu) from ~275m and 43.80m at 0.59% CuEq (0.47% Cu) from ~40m, plus high‑grade intervals up to 4.91% Cu (1.4m).
The release notes copper in 8 of 11 holes, composite reporting rules, assumed 80% recoveries for CuEq, ~11,000m drilled to date, and a planned second‑phase program of up to 15,000m with continued drilling and geophysics.
C3 Metals (OTCQB: CUAUF, TSXV: CCCM) reports new geochronology at its 100%‑owned Khaleesi copper project, southern Peru. Molybdenite Re‑Os ages of ~35.7–35.9 Ma align Khaleesi with nearby large porphyry‑skarn mines Las Bambas and Antapaccay. Older U‑Pb ages of ~39–40.5 Ma from diorite and garnet indicate a multi‑phase hydrothermal system. The company has completed 12 holes (6,300m) with copper observed and plans an additional ~15,000m program through 2026.
C3 Metals (OTCQB: CUAUF) reported initial Phase 1 drilling at the 100%‑owned Khaleesi copper project in southern Peru. Twelve diamond holes (6,300m) all intersected copper within a 1,000m by 500m footprint; step-outs reached 300m. Key intercepts include 269.0m @ 0.30% Cu and 243.7m @ 0.24% Cu.
The company plans up to an additional 15,000m in 2026 (total ~21,300m) to test skarn, quartz veining and porphyry potential; assays and resource modeling are ongoing.
C3 Metals (OTCQB: CUAUF) reported drill results from the second hole at the 100%-owned Khaleesi copper project in Peru on January 21, 2026. The hole intersected 51.1m at 0.54% Cu, 0.31 g/t Au, 3.21 g/t Ag (0.86% CuEq) from 339.6m, including 39.1m at 0.66% Cu (1.06% CuEq) and a higher-grade zone of 18.0m at 1.08% Cu and 0.76 g/t Au (1.85% CuEq). A shallower intercept of 8.0m at 0.42% Cu was reported from 13.9m. The high-grade zone shows porphyry-style veinlets overprinting garnet skarn and remains open along strike and at depth.
Approximately 4,200m of a 6,300m maiden program are complete; eight holes are finished, assays pending for six, and two holes are in progress. Results are downhole lengths; true thicknesses and metallurgical recoveries are not yet established.
C3 Metals (OTCQB: CUAUF) announced restoration of project infrastructure in Jamaica and the restart of full exploration activities after Hurricane Melissa (landfall Oct 28, 2025). At the 50%-owned Super Block scout drilling program (14 holes, 2,500m) seven holes (~50%) are complete and drilling has recommenced. At the 100%-owned Bellas Gate project Freeport is funding exploration under an earn-in and Company drilling has resumed; a 70 sq. km 3DIP survey is ~46 sq. km complete. The company delivered community aid to ~500 families and repaired roads and housing.
