C3 Metals Intersects 164.6 Metres at 0.35% and 119.5 Metres at 0.30% Copper Equivalent at Its Khaleesi Project, Peru - Mineralization Extended North
New Khaleesi drill results in Peru expand a large copper skarn system supported by geophysical data, with more drilling and 3DIP work ahead.
Rhea-AI Summary
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.

- Mineralization confirmed to a vertical depth of approximately 500m and over 500m in east-west dimension (Figure 2).
Dan Symons, President and CEO, stated, "We continue to drill broad intervals of copper mineralization at grades that are very consistent with the mineral reserve grades reported from the nearby Constancia mine operated by Hudbay Minerals. A mineralized intrusive and skarn zone to a depth of 500m immediately beneath a thin layer of glacial till cover has now been established. This zone is currently more than 500m in east-west dimension and remains open to the north, east and west. Importantly, a combination of new gravity and magnetic geophysical data is correlating extremely well with magnetite skarn hosted copper mineralization in drilling. This new geophysical data is showing us several additional drill targets."

To date, approximately 15,100m of drilling has been completed in 33 holes (from 17 drill platforms) with one additional hole in progress (Table 2). Drilling is targeting a northwest trending contact zone between a multi-phase intrusive complex and carbonate rocks of the Ferrobamba Formation along the well-known Andahuaylas-Yauri copper belt.
Drilling has defined five styles of mineralization to date (Figure 2), including:
- Secondary copper species in a near-surface enrichment zone within the multi-phase intrusive complex;
- Primary low to moderate chalcopyrite - bornite - molybdenite mineralization in the intrusive complex below the enrichment zone;
- Chalcopyrite - bornite - molybdenite mineralization in garnet, pyroxene and magnetite skarns;
- High-grade, mantos-style copper mineralization; and,
- Narrow intermediate-sulphidation epithermal veins hosting base and precious metal mineralization.
Near surface diorite hosted in-situ secondary copper mineralization varies from 25m to 100m in true thickness and transitions to chalcopyrite-bornite-molybdenite mineralization at depth. There are "rafts" of magnetite skarn within the diorite that appear rootless. The main skarn body occurs at 300m depth and comprises 1) garnet - pyroxene endoskarn altered diorite 2) garnet - pyroxene exoskarn and an iron-rich magnetite exoskarn replacing dolomite of the Ferrobamba Formation. The east dipping skarn has been confirmed to be more than 500m in east-west dimension, varies from 50m to 200m in true thickness and remains open to the north, east and west (Figure 3). Below the main skarn body is a weakly mineralized diorite.

Next Steps
Drone magnetic and gravity surveys were recently completed over an initial area of 900 hectares. This new data correlates well with existing drill data where a large coincident magnetic and gravity high is demonstrated to be a copper mineralized skarn body over 500m in east-west dimension and down to 500m depth, which remains open to the north, east and west. Due to the success of the surveys at identifying additional coincident magnetic and gravity highs, the Company has expanded the survey area by an additional 600 hectares or over
The Company had planned for a 3DIP survey to be undertaken during August and September (see press release dated June 24, 2026). Commencement of the survey was delayed due to contractor delays importing the necessary equipment into Peru. The 3DIP survey is now scheduled to commence before the end of September and be completed during Q4. 3DIP data is crucial for drill targeting potential porphyry sources or causative intrusives for two reasons:
- It detects chargeability highs from surface to a depth of approximately 1km to indicate the presence and intensity of sulphide minerals; and,
- It provides conductivity and resistivity data to a depth approximately 1km to indicate rock units that are more conductive or resistive to mineralizing fluid flow.
Additionally, surface mapping and soil sampling continues across the broader Khaleesi project area and is expected to be completed in during Q4. The Company continues drilling and is testing additional skarn targets and expanding on the known skarn and diorite mineralization.
The Company looks forward to reporting geophysics survey results and additional assay results as they become available.

Khaleesi is located 8km west of the Company's Jasperoide Project, where the Company confirmed 13 skarn prospects along a 28km iron-skarn belt. Montana de Cobre ("MCZ") is the only skarn along the 28km iron-skarn belt that the Company has systematically drill tested to date, yielding a near surface Measured and Indicated Mineral Resource of 51.9 million tonnes at
The Khaleesi project is situated along a highly favorable limestone-intrusive rock contact zone that bisects the tenement area and trends north-northeasterly. The limestone rock unit is part of the highly receptive Ferrobamba Formation, and the intrusive rock comprises the well-known Andahuaylas-Yauri Batholith. At this contact zone is a multiphase intrusive complex that also appears to trend northeast-southwest, that follows and exploits the contact zone, which is mostly covered by a thin layer of glacial till.

FAQ
AI-generated questions and answers. How Rhea-AI works. Not financial advice.
How is copper equivalent (CuEq) calculated for the Khaleesi drill results?
CuEq is calculated using three‑year trailing average prices of US$4.18/lb Cu, US$2,600/oz Au, US$30.54/oz Ag and US$21.46/lb Mo, with 80% metallurgical recoveries assumed for all metals. The formula is: CuEq % = Cu % + (0.907 × Au g/t) + (0.0107 × Ag g/t) + (0.00051 × Mo ppm). The company notes that Khaleesi is an early‑stage project with no metallurgical test work yet completed.
What work programs are planned next at the Khaleesi project?
The company plans to start a 3DIP survey before the end of September and complete it in Q4, providing chargeability, conductivity and resistivity data to roughly 1 km depth for drill targeting. Surface mapping and soil sampling across the broader project area are also expected to finish during Q4, while drilling continues to test additional skarn targets and expand known skarn and diorite mineralization.
How extensive is the drilling completed so far at Khaleesi and what target is being tested?
Approximately 15,100m of drilling has been completed in 33 holes from 17 drill platforms, with one additional hole in progress. Drilling targets a northwest‑trending contact between a multiphase intrusive complex and Ferrobamba Formation carbonates along the Andahuaylas‑Yauri copper belt, testing intrusive‑ and skarn‑hosted copper mineralization.
