Coppernico Channel Samples 52 m of 1.06% Copper at Sombrero in Peru

VANCOUVER, British Columbia, Sept. 04, 2025 (GLOBE NEWSWIRE) -- Coppernico Metals Inc. (TSX: COPR, OTCQB: CPPMF, FSE: 9I3) (“Coppernico” or the “Company”), through its wholly owned Peruvian subsidiary, Sombrero Minerales SAC, is pleased to announce initial surface channel sampling results from the Nioc target area at its flagship Sombrero copper-gold Project in Peru (Figure 1), including 52 metres (“m”) of 1.06% copper (“Cu”), 0.19 g/t gold (“Au”) and 1.20 g/t silver (“Ag”), and 36 m of 1.10% Cu, 0.32 g/t Au and 3.44 g/t Ag. These results provide an initial view of the high-grade copper-gold mineralization at Nioc and highlight the potential scale of a second major skarn system within the Project, with a continued record of incident-free exploration since inception.

The Company further notes that Ivan Bebek, Chair and CEO, will present at the upcoming Precious Metals Summit Beaver Creek Conference on Thursday, September 11, 2025, at 10:30 a.m., followed by a series of additional conferences through early 2026, providing opportunities for investors to meet directly with management.

Highlights:

• Zone 1:
  • 25SRT029: 52 m of 1.06% Cu, 0.19 g/t Au, and 1.20 g/t Ag
  • 25SRT030: 40 m of 0.96% Cu, 0.13 g/t Au, and 0.96 g/t Ag
  • 25SRT032: 93.5 m of 0.87% Cu, 0.19 g/t Au, and 0.60 g/t Ag
• Zone 2:
  • 25SRT040: 32 m of 0.59% Cu, 0.23 g/t Au, and 1.44 g/t Ag
  • 25SRT042: 36 m of 1.10% Cu, 0.32 g/t Au, and 3.44 g/t Ag
  • 25SRT043: 26 m of 0.99% Cu, 0.40 g/t Au, and 3.11 g/t Ag

True widths currently unknown, results are summarized in Table 1. These are composites of the entire channel sample length, no portion of the channel was excluded.

• Mineralization remains open, with limits in all directions not yet defined. Similarly, the structural control on mineralization is yet to be assessed.
• These channel samples directly overlie a large 1.8 km x 1.4 km chargeability anomaly¹, suggesting continued sulphide mineralization at depth.

Mr. Bebek commented, “Sombrero is unique both in its large scale and grade and represents numerous tier one exploration opportunities as we continue to receive new impressive results across multiple targets within our significant claim holdings. The results announced today were limited only to hard rock - outcropping rocks and the channel samples are open for considerable expansion over the multi square kilometer underlaying geophysical footprint.

These positive results not only significantly benefit our targeting and increase opportunities for discovery, but they also validate our ongoing community relations activities which are planned to include additional agricultural and employment opportunities.

As we advance our pending permits, we are developing a pipeline of tier one copper-gold skarn exploration targets. We are looking forward to providing updates on permit and additional partnership with the communities in the region in the near term.”

Nioc Channel Sampling

The channel samples were collected across bodies of skarn-altered rock outcropping on surface. They represent the first systematic sampling completed by Coppernico within the Nioc target area, one of multiple mineralized centers within a broadly distributed skarn environment.

Coppernico geologists focused sampling on two zones of outcropping garnet and magnetite skarn (Figures 2 and 3), which carry visible copper oxides and trace sulphides, such features being directly comparable to mineralization observed at the Fierrazo target within the Ccascabamba target area located directly to the south.

The channel sampling program has reported multiple zones of copper-gold mineralization with yet to be defined limits, establishing Nioc as a compelling target for follow-up exploration. Significantly, these mineralized zones overlay a large (1.8 km by 1.4 km) chargeability anomaly (>20 mV/V), that has been modeled to at least 500 m below surface (see news release dated January 17, 2020, issued by predecessor Auryn Resources, now Fury Gold Mines), suggesting potential for broad areas of sulphide mineralization present at depth (Figures 1 and 2). This chargeability target itself is situated within a broader area of discontinuously mapped skarn alteration over an area of approximately 2 km by 3 km.

Length and density weighted assay composites. True thickness is unknown, the highlighted channels are oriented generally perpendicular to rock outcrop and are considered most representative at time of reporting. Reported composites are for the entire length of each channel, no sample/interval was excluded from the composite calculation. No more than 6 m internal dilution (reported values below 0.2% Cu). Minimum reporting length of 6 m.

Figure 4: Nioc target view looking SE with delineations of channel sampling Zones 1 and 2, and garnet-magnetite skarn outcrop with visible copper oxides and trace sulphides.

Representative samples include: 25STR-043 (G691308): Garnet–magnetite skarn with chrysocolla filling open spaces, grading 2.81% Cu, 1.19 g/t Au, 2.24 g/t Ag; and Y209449: Magnetite skarn with silicification, pyrite, chalcopyrite, and chrysocolla filling open spaces, grading 3.1% Cu, 0.55 g/t Au, 8.7 g/t Ag.

Sampling Protocols: The composites include 100% of samples collected in each channel, no samples were excluded. The lowest grade sample collected was 0.1% Cu with the highest being 5% Cu. Channel samples were collected from discontinuous outcrops across areas approximately 100 m long and 20–50 m wide. Sampling was conducted where outcrop exposure allowed, with channels oriented to maximize continuity. Due to limited exposure and unknown mineralization geometry, not all channels are perpendicular to the outcrop. Channel sample spacing ranges from 5m to 20m apart. Nearly every channel started or ended elevated Cu grades. The scale of mineralization on surface has yet to be defined. Additional channel sampling and mapping will be required to better define the orientation and extent of mineralization.

Tim Kingsley, VP Exploration, commented, “These maiden results from Nioc are further validation of the thesis of extensive district-scale mineralization at Sombrero. With high-grade copper values directly above a large chargeability footprint, Nioc is shaping up to be a major target area alongside the adjacent Ccascabamba target area. The mineralization on surface at Nioc has similarities to that observed at Fierrazo, where historical drilling has already demonstrated continuity in the third dimension. This work at Nioc represents part of our ongoing efforts to advance a pipeline of large scale and high priority targets aiming to realize the full potential of the Sombrero Project.”

Next Steps

Coppernico plans to expand surface exploration work at Nioc, including additional detailed mapping and channel sampling to further refine the geometry, scale, and continuity of mineralization and associated structures. These efforts will guide future drill targeting, which the Company intends to commence at the earliest opportunity once a community agreement is achieved, to support the broader exploration strategy across the Sombrero Project.

Technical Disclosure and Qualified Person

The scientific and technical information contained in this news release was reviewed and approved by Tim Kingsley, M.Sc., CPG, Coppernico’s VP of Exploration, who is a “Qualified Person” (as defined in NI 43-101).

Quality Control

Analytical samples were taken by chisel and hammer in continuous horizontal lines, typically samples were composited over up to 2 metre lengths per sample, however this may be reduced to 0.5 metres where lithological or significant mineralogical changes were observed in order to accurately reflect the apparent width of mineralisation. Typical sample weights were 1 kg per metre. Samples were collected in plastic bags and given a unique reference number. Approximately 2-3 kg of material per sample was collected for analysis and sent to the ALS Lab in Lima, Peru for preparation and analysis. Preparation included crushing the sample to 90% < 2mm and pulverizing 1,000 g of crushed material to better than 95% < 106 microns. All samples are assayed using 30 g nominal weight fire assay with atomic absorption finish (Au-AA23) and multi-element using four acid digest ICP-AES/ICP-MS method (ME-MS61). Where MS61 results were greater or near 10,000 ppm Cu, or 10,000 ppm Zn the assays were repeated with ore grade four acid digest method (Cu-OG62). QA/QC programs for 2025 channel samples using internal standard samples, blanks, and duplicates, lab duplicates, lab standards, and lab blanks indicate good overall accuracy and precision.
