VANCOUVER, British Columbia – Coppernico Metals Inc. (TSX: COPR, OTCQB: CPPMF, FSE: 9I3) has announced additional surface channel sampling results from the Nioc target area at its Sombrero copper-gold project in Peru. These results significantly expand the known surface footprint of copper-gold mineralization at Zone 2 and materially de-risk initial drill targeting decisions by demonstrating continuous, high-grade skarn mineralization across a broad footprint directly above a large, coherent geophysical anomaly. This reinforces the company's interpretation of Nioc as a large skarn system genetically linked to a porphyry-style intrusive center, offering substantial exploration upside.
Highlights of the Sampling Program
The combined channel (26SRT-109/25SRT-042/26SRT-110) returned 70.1 meters of 0.92% copper, 0.25 grams per tonne gold, and 2.45 grams per tonne silver. This combined interval includes the previously reported 25SRT-042, which returned 36.0 meters of 1.10% copper, 0.32 g/t gold, and 3.44 g/t silver, as announced in a press release dated September 4, 2025.
Step-out channel 26SRT-111 returned 58.0 meters of 0.58% copper, 0.39 g/t gold, and 1.70 g/t silver, including 38.0 meters of 0.60% copper, 0.55 g/t gold, and 2.04 g/t silver. This channel is located approximately 120 meters north of the combined channel line, and mineralization remains open to the north.
These new results nearly double the width of surface mineralization at Zone 2 to about 70 meters in the east-west direction, compared to the initial approximately 36 meters reported on September 4, 2025. Combined Zone 1 and Zone 2 results now define a broad, still-open surface expression of copper-gold skarn mineralization above the more than 1.5 kilometer Nioc coincident geophysical target, strengthening confidence in initial drill targeting across the target area.
CEO Commentary
Ivan Bebek, Chair and CEO of Coppernico, commented: “These results are significant in both grade and width of copper-gold mineralization at our Nioc target. Doubling the width of the east-west surface mineralization in Zone 2 and the meaningful results from the step-out to the north reinforces our view that Nioc is one of the high-priority opportunities within the Sombrero Project, much like Fierrazo, where we expect to commence our next phase of drilling in an effort to expand the Fierrazo discovery.”
Bebek added: “Sombrero has progressively strengthened its pipeline of seven significant drill-ready targets with each layer of data collected; the company is now in the final stages of advancing significant permit expansions with updates expected in the coming weeks.”
Zone 2 Results in Detail
The most recent results build on previously reported Zone 2 channel sampling and represent a continued program of systematic hand-cut channel sampling designed to better define the limits and geometry of mineralization. The combined 26SRT-109, 25SRT-042, and 26SRT-110 channel line extends mineralization along the same interpreted east-west trend and returned a combined composite result of 70.1 meters of 0.92% copper, 0.25 g/t gold, and 2.45 g/t silver. Step-out channel 26SRT-111, located approximately 120 meters to the north, returned 58.0 meters of 0.58% copper, 0.39 g/t gold, and 1.70 g/t silver, demonstrating a meaningful northward expansion of the Zone 2 footprint.

Figure 2 provides an interpreted cross-section through Nioc Zones 1 and 2 incorporating composite channel sample intervals and interpreted skarn–intrusive contacts. Subsurface geometry is projected from surface orientation measurements of the skarn–intrusive contact; the depicted continuity and thickness are interpretive and subject to refinement with drilling or additional mapping.
