C3 Metals Inc. (TSXV: CCCM; OTCQB: CUAUF), the Canadian-listed copper and gold explorer operating in Peru and Jamaica, has intersected 64.9 metres grading 3.45% copper equivalent at its wholly owned Khaleesi Project in southern Peru. The drilling results released on 2 November 2026 include a higher-grade interval of 23.3 metres at 6.64% copper equivalent, representing the strongest copper and gold mineralisation reported so far from the company’s exploration programme. The broader interval contains 2.53% copper, 0.87 grams per tonne gold and 11.6 grams per tonne silver, while the higher-grade section contains 4.75% copper and 1.84 grams per tonne gold. The results provide an encouraging geological signal within the Andahuaylas-Yauri copper belt, but the company has not declared a Mineral Resource at Khaleesi, and the reported copper-equivalent calculations use assumed recoveries that have not yet been validated through project-specific metallurgical testing.
Why is C3 Metals’ 64.9-metre copper intersection significant for the Khaleesi exploration programme?
Drillhole KHZ5790-005 intersected 64.9 metres containing 2.53% copper, 0.87 grams per tonne gold, 11.6 grams per tonne silver and minor molybdenum. The company calculated a combined grade of 3.45% copper equivalent using specified commodity price and recovery assumptions. The intersection began at approximately 337.6 metres downhole, placing the reported mineralisation well below surface. Its significance lies in both the grade and the thickness of mineralisation encountered within the targeted skarn system.
The higher-grade internal section returned 23.3 metres containing 4.75% copper, 1.84 grams per tonne gold and 20.4 grams per tonne silver. Its copper-equivalent grade was calculated at 6.64%. These results indicate that the broader mineralised system contains zones with substantially higher metal concentrations than the average interval. However, the depth and geometry of the zone will influence whether those grades can eventually support economic mining.
C3 Metals described the intersection as the highest-grade copper and gold mineralisation encountered so far at Khaleesi. The hole was designed to investigate a magnetite and garnet skarn body in an area that had received limited previous drilling. The results therefore provide new geological information rather than simply confirming an extensively defined resource. Additional drilling is needed to establish whether similar grades continue in surrounding areas.
The company is now prioritising step-out drilling at distances of approximately 50 to 100 metres. These holes are intended to test the shape, continuity and extent of the high-grade zone. A single strong intersection can materially improve exploration interest, but resource estimation requires a sufficiently dense and consistent body of geological evidence. The next drill results will determine whether the zone can be interpreted as part of a larger deposit.
What does the 23.3-metre interval at 6.64% copper equivalent actually measure?
Copper equivalent combines the economic contribution of several metals into a single copper-based grade under stated assumptions. At Khaleesi, the calculation includes copper, gold, silver and molybdenum. C3 Metals has used trailing average commodity prices covering 2023 through 2025 and assumed 80% metallurgical recovery for each metal. The figure is therefore an analytical comparison rather than a direct laboratory measurement of copper content.
The distinction is particularly important because the high-grade interval contains 4.75% copper, not 6.64% copper. The difference reflects the calculated value contribution of gold, silver and minor molybdenum. Those metals could improve future project economics if they can be recovered and sold commercially. However, their actual contribution depends on metallurgical processing and payable metal arrangements.
C3 Metals has acknowledged that no project-specific metallurgical test work has yet been completed at Khaleesi. The assumed 80% recovery across all metals is therefore a preliminary reporting assumption. Actual recoveries could differ materially depending on mineralogy, processing technology and operating conditions. A future economic study would need more robust recovery data before assigning financial value to the metal content.
The reported intersections also represent downhole lengths rather than confirmed true geological thicknesses. A drillhole may cross a mineralised body at an angle, making the measured interval longer than its actual thickness. C3 Metals has not yet established true widths for the latest intervals. That information will require additional drilling and geological modelling.
These limitations do not negate the encouraging assay results, but they constrain the conclusions that can be drawn. High grades can indicate an attractive exploration target while still leaving major questions about deposit geometry and commercial extraction. A credible resource estimate will need to account for those factors. Until then, the drill results should be understood as exploration evidence rather than a production forecast.
Why is Khaleesi’s location in Peru’s Andahuaylas-Yauri copper belt important?
Khaleesi lies within the Andahuaylas-Yauri copper belt in southern Peru, a mineralised region associated with significant copper deposits. The project is located within the same broad geological corridor as major operations including Las Bambas and Constancia. This regional context supports exploration interest because it demonstrates the presence of large copper-bearing geological systems. However, proximity to established mines does not establish that Khaleesi contains a deposit of comparable size or economic value.
The project’s geology includes skarn mineralisation formed near contacts between intrusive rocks and carbonate formations. C3 Metals has identified copper-bearing minerals including chalcopyrite and bornite across parts of the system. These mineral associations can be relevant to the exploration of copper and precious metals. The distribution of grades and mineral types will influence future processing and mining assessments.
Mapping has identified an extensive skarn system covering approximately 1,200 metres by 1,000 metres. The company has also traced epithermal quartz-sulphide veins over roughly two kilometres. These observations suggest that mineralising processes affected a substantial area. Nevertheless, the mapped extent of altered or mineralised rocks should not be treated as an equivalent area of economically mineable ore.
Parts of the central project area are covered by glacial material, limiting direct observation of the underlying geology. This creates uncertainty about how different mineralised zones connect beneath the cover. Geophysical surveys and drilling are being used to investigate those relationships. The potential presence of additional concealed mineralisation remains an exploration hypothesis rather than a confirmed resource.
The regional location also creates future development considerations. Peru has an established copper mining industry, but project economics depend on local infrastructure, environmental requirements, community engagement and transport logistics. A future discovery would need to progress through those processes before mining could begin. The company’s current programme is focused on geological evaluation rather than construction.
How much drilling has C3 Metals completed, and what remains to be investigated?
C3 Metals reported approximately 16,830 metres of drilling across 38 completed holes at Khaleesi, with another hole in progress. The programme has used 17 drill platforms to investigate different parts of the mineralised system. This represents substantial exploration activity compared with the early stages of a grassroots prospect. However, the overall area under investigation remains large relative to the density of drilling.
Previous exploration has identified several styles of mineralisation. These include copper associated with intrusive rocks, higher-grade skarn zones, near-surface enrichment and narrower precious-metal-bearing structures. Different mineralisation types may require different geological interpretations and processing approaches. The company must establish how these occurrences relate spatially before constructing a reliable deposit model.
Recent drilling has also extended lower-grade mineralisation toward the eastern part of the project. In late October, C3 Metals reported intersections including 101.9 metres grading 0.38% copper equivalent and 70.9 metres grading 0.62% copper equivalent. Those results differ substantially from the new high-grade intersection. Their comparison illustrates why a large mineralised system can contain zones with very different metal concentrations.
The latest high-grade results create an opportunity to investigate whether richer portions of the system are connected. If additional drilling identifies continuity across a substantial volume, the geological significance could increase. Conversely, the high-grade material may prove relatively restricted in extent. Both possibilities remain open until further assays are received.
C3 Metals has indicated that results from drillholes KHZ5790-006 and KHZ5790-007 remain outstanding. Their assays may provide additional information about adjacent mineralisation. However, results from nearby holes cannot be assumed to match the grades reported from KHZ5790-005. The spacing, direction and depth of each hole will determine how effectively it tests continuity.
How could magnetic, gravity and electrical surveys improve the understanding of Khaleesi?
C3 Metals has completed drone-based magnetic and gravity surveys covering approximately 1,500 hectares. The company is processing the resulting data to investigate geological structures and possible mineralised targets beneath surface cover. These techniques measure differences in physical properties that can be associated with particular rock types or mineralisation. They provide useful exploration guidance but do not directly establish metal grades.
A three-dimensional induced polarisation survey is also underway, with completion expected during November 2026. The survey is intended to identify electrical characteristics potentially associated with sulphide mineralisation. Integrating these results with magnetic, gravity and drilling information may help the company refine its geological model. This could support more efficient targeting of future holes.
The surveys may also help investigate the possibility of a deeper porphyry system associated with the skarn mineralisation. Large copper deposits can contain different geological zones linked to intrusive processes. However, identifying a potential porphyry source does not establish that an economically significant deposit exists. Drilling remains necessary to confirm mineralisation and assess its grade.
Exploration efficiency matters because drilling is expensive, particularly where targets lie hundreds of metres below surface. Better geological targeting may reduce the number of unproductive holes needed to test the system. Nevertheless, geophysical anomalies can arise from rocks that do not contain economically attractive mineralisation. The company’s interpretation must therefore be tested through assays and physical geological evidence.
The integration of surveys and drilling will influence the next phase of Khaleesi exploration. Successful results could justify more extensive drilling or the preparation of an initial resource model. However, additional financing and technical work may be required as the programme grows. The company has not announced a date for a maiden Mineral Resource estimate.
What would C3 Metals need to establish before Khaleesi could become a copper mining project?
The first requirement is demonstrating sufficient continuity and scale. A collection of high-grade drill intersections is not equivalent to a mineable deposit unless the mineralised material can be modelled with appropriate confidence. Further drilling must establish the extent, grade distribution and geometry of the system. The resulting information would support the preparation of a Mineral Resource if the relevant criteria are met.
Metallurgical testing is another essential requirement. The company must determine how much copper, gold and silver can be recovered using a suitable processing method. Mineralogy, recovery and concentrate quality can materially influence project economics. The assumed 80% recovery used in the current copper-equivalent calculations is not a substitute for this work.
A future mining study would also need to evaluate open-pit or underground development options, depending on deposit depth and shape. The latest high-grade intersection begins more than 300 metres downhole, making depth and access relevant considerations. Infrastructure, water, power and transport requirements would need to be quantified. These studies could involve substantial expenditure before any development decision.
The market environment will also influence the investment case. Copper demand is supported by electricity infrastructure, industrial equipment and other applications, but prices remain cyclical. Gold and silver credits may strengthen potential economics if recoveries are commercially viable. However, favourable commodity markets cannot overcome inadequate deposit scale or high extraction costs indefinitely.
The November drilling result is encouraging because it provides the strongest high-grade evidence reported so far at Khaleesi. It does not establish a resource, reserve or commercial mine. Follow-up drilling and metallurgical work will determine whether the discovery can progress from geological potential to a financially credible development opportunity.
What should investors watch after C3 Metals’ strongest Khaleesi copper discovery?
C3 Metals’ next meaningful milestone is confirmation of mineralisation continuity around drillhole KHZ5790-005. Step-out holes will test whether the 64.9-metre high-grade interval extends across adjacent sections. Additional assays could materially improve or constrain the geological interpretation. The company must also establish true widths before the scale of the zone can be assessed with greater confidence.
The geophysical programme provides another source of information. Combining the survey results with drilling may identify new targets or clarify the broader mineralised system. However, exploration success should be judged by confirmed assays and geological continuity rather than the number of anomalies generated. Future resource estimation will require sufficient drilling density and technical evidence.
The results demonstrate that Khaleesi contains potentially attractive copper and precious-metal grades within parts of the system. Their economic significance remains uncertain because the deposit has not been defined and metallurgical testing is outstanding. Strong follow-up results could support further investment in exploration. Until then, C3 Metals remains an exploration-stage company rather than a producer with established project cash flow.
