Coppernico Channel Samples Intersect 70.1 m of 0.92% Copper and 0.25 g/t Gold at Nioc

VANCOUVER, British Columbia, May 19, 2026 (GLOBE NEWSWIRE) -- Coppernico Metals Inc. (TSX: COPR, OTCQB: CPPMF, FSE: 9I3) (“Coppernico” or the “Company”) is pleased to announce additional surface channel sampling results from the Nioc target area at its Sombrero copper-gold Project in Peru. These results 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, with significant exploration upside.

Highlights Combined channel (26SRT-109/25SRT-042/26SRT-110) returned 70.1 m* of 0.92% Cu, 0.25 g/t Au and 2.45 g/t Ag (Figure 1 and Table 1). The combined interval includes previously reported 25SRT-042 which returned 36.0 m of 1.10% Cu, 0.32 g/t Au and 3.44 g/t Ag; see press release dated September 4, 2025. Step-out channel 26SRT-111 returned 58.0 m of 0.58% Cu, 0.39 g/t Au and 1.70 g/t Ag , including 38.0 m of 0.60% Cu, 0.55 g/t Au and 2.04 g/t Ag, located approximately 120 m north of the combined channel line.

Mineralization remains open to the north. New results nearly double the width of surface mineralization at Zone 2 to about 70 m in the east-west direction relative to the initial approximately 36 m 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 >1.5 km Nioc coincident geophysical target, strengthening confidence in initial drill targeting across the target area. * (m = metres, Cu = Copper, g/t = grams per tonne, Au = Gold and Ag = Silver) 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.
