PECOY COPPER TO COMMENCE DRILLING ACTIVITIES SHORTLY

Drilling activities are scheduled to commence in the coming weeks at Pecoy Copper Corp.'s flagship Pecoy copper-gold-molybdenum-silver project located in southern Peru.

This milestone follows months of intensive technical, regulatory and community preparation, including the renewal of drilling and access permits, updated environmental approvals, and community agreements required to initiate the upcoming program.

The company extends its appreciation to its community partners and local stakeholders, with whom it looks forward to working closely throughout the drilling campaign to ensure that activities are conducted safely, responsibly, transparently and collaboratively.

First drilling program at Pecoy in nearly a decade

This program marks the first drilling at Pecoy since 2016, following the successful consolidation of the project and completion of Pecoy Copper's go-public transaction in September, 2025. The new program aims to expand the mineralized footprint and demonstrate the full potential of the unified Pecoy deposit, a large, well-defined copper-gold-molybdenum system with significant growth potential.

Historically, exploration at Pecoy was conducted by multiple operators pursuing independent objectives, resulting in uncoordinated drilling and limited regional integration. With the project now consolidated under a single entity, Pecoy Copper can execute a comprehensive, data-driven exploration strategy designed to fill historical gaps, define high-grade zones, extend known zones of mineralization and unlock the project's long-term value through a systematic approach.

Vincent Metcalfe, chief executive officer of Pecoy Copper, commented: "With copper and gold markets strengthening, this is a timely moment to initiate drilling at Pecoy. Global structural demand for copper continues to rise amid accelerating investment in electrification and infrastructure. This next phase of development will allow us to realize the full potential of the Pecoy deposit and significantly advance one of the most exciting undeveloped copper assets in the Americas, while deepening our collaboration and relationships with host communities and local stakeholders as we move the project together."

The company will provide further updates on drilling activities, program scope and exploration objectives as activities progress.

About Pecoy Copper Corp.

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 per cent 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 deepwater ports of Matarani (approximately 240 kilometres 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 Exchange under the symbol PCU and also trade on the OTCQB under the symbol PCUUF.
