Coppernico Confirms Large-Scale Copper Skarn System and Expands Pipeline of Priority Targets at Sombrero

Rhea-AI Summary

Coppernico Metals (CPPMF) has reported final assay results from its Phase 1 drill program at the Sombrero Project in Peru, confirming a large-scale copper-gold skarn system. The program completed 8,232.9 meters of diamond drilling across 20 holes at the Ccascabamba target area. Notable intercepts include 9.85m @ 0.26% copper and 0.46 g/t gold (25SOM-013) and 21.85m @ 0.22% copper (25SOM-018). The company has temporarily paused drilling to pursue expanded permits for accessing priority targets. The results demonstrate broad mineralization intervals and multiple zones, with alteration zones exceeding 300 meters in width. Regional exploration programs are ongoing, with new targets identified at Nioc, Tipicancha, Macha Machay, and Cello areas. The company plans to resume drilling in the second half of 2025 once new permits are secured.

VANCOUVER, British Columbia, May 14, 2025 (GLOBE NEWSWIRE) -- Coppernico Metals Inc. (TSX: COPR, OTCQB: CPPMF) (“Coppernico” or the “Company”), is pleased to report the remaining assay results from its Phase 1 drill program at its Sombrero Project in Peru. The program, conducted through its wholly owned Peruvian subsidiary, Sombrero Minerales SAC, included 8,232.9 metres (“m”) of diamond drilling over 20 holes designed to test large-scale geophysical and geochemical anomalies within the Ccascabamba target area. The results confirm broad intervals of copper-gold mineralization supporting the technical team’s skarn-porphyry geological model and reinforcing the district-scale potential of the Sombrero Project. Drilling is now temporarily paused as the Company pursues expanded permits for access to priority targets.

Phase 1 Drill Program Highlights:

• Large System: Drilling to date has not yet defined the limits of the skarn system, with mineralization and alteration vectoring high-priority opportunities well beyond the currently permitted area. Surface mapping, geophysical data and historical drilling suggest continuity and highlights the potential for the discovery of major extensions in future phases.
• Notable Intercepts from Drill Holes 6-20:
  • 25SOM-013 – 9.85 m @ 0.26% copper (“Cu”) and 0.46 g/t gold (“Au”)
  • 25SOM-016 – 9.40 m @ 0.19% Cu
  • 25SOM-017 – 18.10 m @ 0.18% Cu and 0.7 g/t Au
  • 25SOM-018 – 21.85 m @ 0.22% Cu
  • 24SOM-007 – 9.15 m @ 0.21% Cu
• Intrusive Igneous Rock Architecture: Drilling to date has defined a complex network of causative intrusions, particularly around the Hojota area, where much of the Phase 1 drill program was focused.
• Zonation and Controls: Mineralization appears to be controlled by an interplay of factors including proximity to causative intrusions, favorable host lithologies and zones of impermeability and structural complexity, including intersecting fault sets.
• Robust Skarn Alteration: Alteration zones exceeding 300 meters in width have been defined, characterized by multiple skarn-forming events and broad breccia zones.
• High-Priority Targets Beyond Current Permits: Several compelling targets lie outside the currently permitted drill polygon, where the data is pointing to even more prospective zones for future drilling.
  

Geological and geochemical results from the Phase 1 drill program (Table 1) demonstrate continuity of copper-gold mineralization across broad intervals and multiple zones. Prospective contact zones between intrusive rocks and limestone, highlighted by magnetic data (Figure 1), indicate strong exploration potential beyond the current drill permitted area (particularly at Chumpi and at Fierrazo, where historical drill holes show strong potential) which supports the decision to advance an expanded permit application that is actively progressing. Within the existing drill permit (notably at Hojota and Corrales), the intrusion–limestone contact zone has been only partly tested with widely spaced holes, these areas will remain targets for future drill phases.

Additionally, regional exploration programs are underway, designed to optimize the Company's land position and advance a growing pipeline of high-impact exploration targets across the broader Sombrero Project. Further updates on this work are expected to be announced in the coming months as additional data becomes available.

Ivan Bebek, Chair and CEO of Coppernico, stated, "As we deepen our understanding of the Sombrero system, our confidence in the size and potential of the broader district continues to grow. These early drill results confirm our belief that we are only beginning to unlock the value of this largely underexplored, yet highly promising, land package. Although our initial permitted polygon was quite limiting, we have been able to develop a strong pipeline of drill-ready targets across the property and eagerly await the surface data collection on new, high-grade skarn and porphyry targets. Our priority is to secure key permits which are underway, in order to position ourselves to drill the most robust outcropping areas in the next phase of drilling. We are looking forward to additional exploration results and permit advancements as we prepare for a busy second half of 2025.”

Drill holes 6 through 20 confirm the presence of an extensive, high-temperature copper-gold skarn system in the Ccascabamba target area. The results mark a major advancement in the Company’s understanding of this large target, which is predominantly covered by shallow overburden, revealing a robust and laterally continuous system with significant vertical extent. Importantly, geological and geophysical indicators beyond the current mineralized footprint suggest that the system may extend beyond the current permit boundary, reinforcing the potential for a district-scale discovery.

At Hojota, broad intervals of copper anomalism - such as +30-meter zones averaging approximately 0.1% Cu - have been encountered within massive garnet-pyroxene skarn. These zones appear to be laterally continuous over 1 kilometer with significant vertical continuity. Results are interpreted to reflect high-temperature mineralization proximal to causative intrusions, with localized grade enhancements near structural and lithologic traps, such as impermeable hornfels and faults (Figure 2).

“Initial drilling around the Ccascabamba target area has confirmed a significant skarn system, with mineralized alteration extending over 300 meters from the intrusion-limestone contact and vertical continuity of more than 400 meters,” said Tim Kingsley, VP Exploration. “These early indications confirm the presence of a large-scale system, comparable to some of Peru’s most prominent porphyry-skarn deposits, such as Antamina and Las Bambas. With an improved geological model in place, the technical team is now leveraging insights from Phase 1 drilling to refine targets and guide future systematic testing across this highly prospective system.”

Regional Target Pipeline Expands

Coppernico continues to grow its pipeline of copper targets through ongoing mapping and sampling programs beyond the Ccascabamba target area (Figure 3). These efforts are refining the Company's understanding of the broader Sombrero Property potential and informing the strategic advancement of exploration activities. Results of this work are expected to be released in the near future.

Nioc target area: Early results indicate scale and grade potential on par with the Ccascabamba target area. Recent fieldwork has identified a previously unrecognized skarn system approximately 1.5 kilometers north of Nioc, referred to as the Antapampa target, which may represent either an extension of the Nioc system or a new standalone discovery, underscoring the prospectivity of the area.

Tipicancha target: Grassroots exploration southwest of the Ccascabamba target area has outlined a newly recognized copper-mineralized hydrothermal system. This epithermal / porphyry target is being rapidly advanced toward drill-ready status.

Macha Machay and Cello targets: Early stage, 1:10,000 scale mapping has identified multiple, new sulphide bearing alteration systems within these claim groups and additional work is planned to reveal the scale and potential of these new epithermal / porphyry targets.

Permitting Progress: To support the next phase of drilling, the Company is actively advancing its permitting efforts to access high-priority targets located beyond the current drill permit boundaries. These expanded permits will enable broader systematic testing across both newly defined and previously identified highly prospective target areas.
