Pecoy Copper Completes Magnetotelluric Survey to Optimize High-Priority Targeting and Resource Expansion

VANCOUVER, British Columbia, April 22, 2026 (GLOBE NEWSWIRE) — Pecoy Copper Corp. (“Pecoy Copper” or the “Company”) (TSXV: PCU; FSE: D5E; OTCQB: PCUUF) is pleased to announce the completion of a large-scale magnetotelluric (“MT”) geophysical survey at its 100%-owned Pecoy Copper-Gold-Molybdenum-Silver Project (“Pecoy” or the “Project”) located in southern Peru.

The MT survey was designed to optimize and prioritize high-potential expansion targets beneath cover and at depths exceeding 2,000 metres across the Pecoy system. The program is focused on enhancing the Company’s 3D geological model, understanding of the Project’s alteration and structural architecture to support ongoing drilling and broader target generation, particularly in areas interpreted to host concealed porphyry mineralization and extensions to known mineralized zones. This data-driven approach is designed to increase the precision of upcoming step-out drilling and potentially defining further high-grade mineralization.

Key Strategic Objectives

The MT survey covered approximately 760 hectares (2.75 km by 2.75 km) over the Pecoy system and included 85 MT stations designed to generate a high-resolution 3D resistivity model.

• De-risk Exploration: Provide high-resolution resistivity data to assist in defining the geometry and continuity of known mineralized zones.
• Identify New Targets: Isolate potential porphyry centres and breccia-hosted mineralization hidden beneath post-mineral cover and below the current resource pit shell or around known mineralized zones.
• Optimize Capital Allocation: Integrate results with ongoing Phase 1 drilling and existing geochemical datasets to prioritize the most prospective areas within and around the known Pecoy deposit.

Final inversion and interpretation are expected during the second quarter of the 2026 calendar year, with results intended to inform step-out drilling and future exploration planning.

“Pecoy already hosts one of the largest undeveloped copper resources in Peru, yet the system remains open at depth and along strike, with multiple priority zones still underexplored,” said Vincent Metcalfe, President and CEO of Pecoy Copper. “The MT survey represents an important step in refining our understanding of the broader porphyry system and the controls on higher-grade mineralization. By integrating the results with our ongoing drill program and geological reinterpretation, we aim to define concealed targets, prioritize follow-up drilling, and continue to unlock the district-scale potential of Pecoy.”

MT Survey Program

The Deep SPARTAN MT survey was completed by Quantec Geoscience and was designed to map subsurface resistivity variations to depths exceeding 2,000 metres below surface. In porphyry copper systems, MT surveys are an effective tool for imaging large-scale intrusive bodies, lithologies, hydrothermal alteration zones, structures, and potential sulphide-bearing domains that may not be apparent from surface mapping or shallow drilling.

At Pecoy, the survey is expected to provide new information on the geometry and continuity of known mineralized zones, as well as the potential for additional porphyry centres and breccia-hosted mineralization beneath post-mineral cover and below the current resource pit shell. The Company expects the MT survey results to be particularly useful in refining drill targeting in the eastern, western and northwestern portions of the system, the deeper projection of the South Breccia, and the broader Center of the Pit/Central Breccia corridor.

The MT survey forms part of Pecoy Copper’s broader 2026 exploration strategy, which includes ongoing diamond drilling, deposit-scale geological modelling, alteration and vein mapping, and target refinement across the Company’s broader land package.

Pecoy Project Highlights

• Large copper system with an inferred mineral resource of 865 Mt at 0.34% Cu (~6.5 billion pounds of contained copper), with associated gold, molybdenum and silver credits
• Surface exposure and multiple breccia centres, including the South Breccia
• Favourable topography at Pecoy Hill, with extensive mineralization expressed at surface and consistent with potential open-pit style geometry
• Low elevation (~1,650 m) with year-round access and proximity to infrastructure corridors and deep-water ports
• Additional district-scale upside at Tororume (~8 km north), where all nine historical drill holes intersected mineralization

Grant of share options

The Company also announces that its Board of Directors has granted today share options in respect of 105,000 common shares (the “Options”) to certain directors and consultants pursuant to the Company’s Omnibus Equity Incentive Plan. The Options have an exercise price of $1.79 per common share, being the closing price of the Company’s common shares on the TSX Venture Exchange on April 21, 2026. The Options will vest equally over a three-year period and will expire five years from the date of the grant.

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”.
