Pecoy Copper Intersects 1,020.50 m of 0.43% Cu and 0.09 g/t Au from 48 m in Follow-Up Hole, a Second Consecutive Kilometre-Scale Intercept within South Breccia

VANCOUVER, British Columbia, April 08, 2026 (GLOBE NEWSWIRE) — Pecoy Copper Corp. (“Pecoy Copper” or the “Company”) (TSXV: PCU; FSE: D5E; OTCQB: PCUUF) is pleased to report assay results from drill hole PEC-25-066, completed as part of its ongoing Phase 1 diamond drill program at its 100%-owned Pecoy Project in southern Peru.

Hole PEC-25-066 was drilled in the South Breccia Zone approximately 195 metres west from hole PEC-25-065 and has returned a broad interval of continuous copper-gold-molybdenum-silver mineralization beginning near surface and extending to the end of hole. The results represent an excellent follow-up to PEC-25-065. Together, holes PEC-25-065 and PEC-25-066 have now returned two consecutive kilometre-scale mineralized intervals in the South Breccia Zone, confirming strong lateral and vertical continuity.

PEC-25-066 Highlights:

• Intersected 1,020.50 m at 0.43% Cu, 0.09 g/t Au, 1.51 g/t Ag and 0.009% Mo from 48 m depth, our second kilometre-scale interval in the South Breccia zone.
• Located approximately 195 m west from PEC-25-065.
• Extends mineralization approximately 306 metres below the current resource pit shell.
• Ended in mineralization, remains open at depth.
• The 1,020.50 m copper interval grades ~26% above the current inferred resource grade of 0.34% Cu.

The broad interval includes higher-grade sections:

• 48 m at 0.94% Cu, 0.21 g/t Au, 3.05 g/t Ag, 0.014% Mo from 54 m,
• 242 m at 0.73% Cu, 0.10 g/t Au, 2.63 g/t Ag, 0.016% Mo from 386 m,
• 167.85 m at 0.33% Cu, 0.06 g/t Au, 1.05 g/t Ag, 0.006% Mo from 776 m located below the existing resource pit shell, and;
• 18 m at 0.50% Cu, 0.05 g/t Au, 1.48 g/t Ag, 0.029% Mo from 1050 m to end of hole, indicating the system remains open at depth.

These results and higher-grade sections further reinforce management’s view that South Breccia may contain a higher-grade domain that could be relevant to the evaluation of a potential starter-pit style development concept in future studies, subject to additional drilling, resource modelling, metallurgical work and economic analysis.

Vincent Metcalfe, Chief Executive Officer of Pecoy Copper, commented: “Hole PEC-25-066 is an excellent follow-up and further confirms the scale, continuity and growth potential of the South Breccia system. Importantly, this is now the second consecutive kilometre-scale intercept in the South Breccia zone to confirm a meaningful extension of mineralization below the current pit shell. Drilled approximately 195 metres from hole 065, hole 066 ended in mineralization at 1,068.5 metres, supporting excellent lateral and vertical continuity and reinforcing our interpretation that the South Breccia may host a large, coherent higher-grade domain within the broader Pecoy system. Our systematic drilling continues to strengthen this view and underscores the potential relevance of the South Breccia to future phased development studies.”

Note: True thickness and widths of the mineralization are currently unknown

Hole PEC-25-066 targeted the South Breccia Zone, where mineralization is hosted within brecciated and altered intrusive rocks and is characterized by chalcopyrite, gold, silver and molybdenite, consistent with a large porphyry-related system. The hole was designed as a follow-up to PEC-25-065 to test the lateral continuity of the South Breccia system and its depth potential.

The results from PEC-25-066 confirm another long run of continuous mineralization in the South Breccia Zone and compare favourably with hole PEC-25-065, which previously returned 1,013.75 m grading 0.37% Cu, 0.13 g/t Au, 1.33 g/t Ag and 0.016% Mo from 17 m, including 297.25 m grading 0.52% Cu, 0.07 g/t Au, 1.94 g/t Ag and 0.033% Mo below the current resource pit shell. Hole 066 was collared approximately 195 m west from hole 065 and provides another strong intercept within the same higher-grade South Breccia domain.

Importantly, hole PEC-25-066 extended continuous mineralization approximately 306 m below the current resource pit shell and ended in strong mineralization at 1,068.5 m. The final 18.3 m averaged 0.50% Cu and 0.029% Mo, and the final 8.5 m of the hole averaged 0.57% Cu and 0.041% Mo, indicating the South Breccia system remains open at depth.

The broad interval from 386.0 m to 628.0 m represents the main higher-grade core of the hole and is interpreted to correspond to a coherent potassic-primary South Breccia zone. Within this broader interval, the 134.9 m interval from 390.0 m highlights a stronger internal core. A second broad zone below the current pit shell, from 775.85 m to 943.70 m, demonstrates that meaningful copper-gold-molybdenum mineralization continues well beneath the current resource constraint.

South Breccia

The South Breccia represents one of the most advanced and best-defined mineralized breccia bodies at Pecoy and hosts the higher-grade mineralization encountered to date. Drilling has outlined a coherent geometry with strong continuity, and the breccia remains open laterally and at depth, including toward the west beneath alluvial cover. Hole PEC-25-066 provides further evidence of that continuity and reinforces South Breccia as an emerging higher-grade growth area within the broader Pecoy system.

Phase 1 Progress

To date, approximately 4,911 metres have been drilled during the Phase 1 program, with three holes completed and two additional holes currently in progress. Drilling has now shifted toward testing the Center of the Pit target and Central Breccia areas. Drilling in the South Breccia area will resume once the rainy season ends which is expected at the end April.

As drilling activities continue to ramp up, the Company expects to increase from three to five active drill rigs during the summer. To provide investors with a broader view of ongoing exploration progress, the Company expects that, following this release, future drill results will be reported in batches rather than on a hole-by-hole basis. The next group of drill holes will focus on the Center of the Pit target and the Central Breccia areas, where drilling is designed to test additional resource growth and higher-grade mineralization potential within the broader Pecoy system.

There is very little historical information for the Center of the Pit and Central Breccia areas, as historical drilling in these zones was limited. The target areas represent a 750 metre long by 300 metre wide zone on surface.

Qualified Persons and Technical Notes

The scientific and technical information in this news release has been reviewed and approved by Vincent Cardin-Tremblay, P.Geo., current Chief Geological Officer of Pecoy Copper, a Qualified Person as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

Diamond drill core from the Pecoy Project was logged and sampled at the Company’s secure core facility at site by Company personnel. Drill core was sawn in half, with one half retained for reference and the other half sampled at nominal intervals of up to 2 metres, with sample boundaries adjusted to respect geological contacts. Core diameter varied between HQ, and NQ, depending on depth.

Samples were bagged, sealed, and transported by commercial carrier to the Bureau Veritas preparation laboratory in Arequipa, Peru, where samples were crushed and a 250 g split was pulverized to 85% passing 75 µm (200 mesh). Prepared pulps were then sent and analyzed at the assay laboratory in Lima, Peru. Bureau Veritas is an ISO-accredited laboratory and is independent of the Company.

Gold analyses were performed using fire assay fusion with ICP-OES finish on a 30 g sample (FA330). Samples returning gold values greater than 10 g/t Au were re-analyzed using fire assay with gravimetric finish (FA530). Copper and silver were analyzed by ICP-OES/MS following a four-acid digestion as part of a 45-element multi-element suite (4A200). Samples returning values over the upper detection limit (Au, Ag, Cu, Zn, Mo, Pb) were re-analyzed using four-acid digestion with AAS finish (MA402).

A comprehensive Quality Assurance and Quality Control (QA/QC) program was implemented as part of the sampling and analysis procedures. Certified reference materials, blanks, and duplicate samples (field, preparation, and analytical duplicates) were inserted into the sample stream at regular intervals, representing approximately 15% of the total samples submitted. No significant QA/QC issues were identified during the analysis, and the results are considered reliable for reporting purposes.

Mineral resources are not mineral reserves and do not have demonstrated economic viability.

About Pecoy Copper

Pecoy Copper is advancing the 9,975-hectare Pecoy Copper-Gold-Molybdenum-Silver Project, a large, undeveloped porphyry system located in southern Peru’s Arequipa region, within one of the world’s most prolific copper belts. The Pecoy deposit hosts a current copper inferred resource of 865 million tonnes at 0.34% Cu, with significant associated gold, molybdenum, and silver credits.

To date, less than 49,000 metres of historical drilling have been completed at Pecoy, defining a broad and continuous mineralized system with potential for expansion along strike and at depth. The project benefits from its favourable elevation of approximately 1,650 metres above sea level, providing year-round access and reduced operating complexity compared to many high-altitude Andean deposits.

Strategically located near the Pacific coast, Pecoy enjoys excellent infrastructure, with close proximity to highways, power lines, and water sources, and good access to the deep-water ports of Matarani (approximately 240 km southwest) and Ilo. This infrastructure advantage positions Pecoy Copper to advance the project efficiently from exploration toward future development within one of the world’s most established and mining-friendly jurisdictions.

The Company’s common shares are listed on the TSX Venture under the symbol “PCU” and also trade on the OTCQB under the symbol “PCUUF”.
