PECOY COPPER COMMENCES THIRD DRILL RIG AS EXPLORATION MOMENTUM BUILDS

A third drill rig has commenced operations as part of Pecoy Copper Corp.'s continuing exploration drilling program at its 100-per-cent-owned Pecoy copper-gold-molybdenum-silver project, located in southern Peru.

The addition of the third drill rig increases the company's active drilling capacity and is expected to support the continued advancement of the current planned 35,000-metre diamond drilling program at Pecoy. The program is focused on testing high-priority copper targets, expanding the company's geological understanding and following up on areas of interest identified through previous exploration work.

Drilling is currently under way across the Center of the Pit and Central Breccia zones, with the third drill rig reinitiating drilling activities in the South Breccia zone.

"The commencement of a third drill rig marks an important step forward for Pecoy Copper as we continue to advance our exploration program. With the rainy season now behind us, we expect drilling activities to intensify in the coming months," said Vincent Metcalfe, president and chief executive officer of Pecoy Copper. "Increased drilling capacity will allow us to test priority targets more efficiently and continue building a more comprehensive understanding of the project's potential."

The company views the current drilling campaign as a key phase in the systematic evaluation and expansion of the project and deposit. Pecoy Copper remains committed to executing the program safely, responsibly, and in close co-ordination with local stakeholders and technical teams on the ground.

Further updates will be provided as the drilling program progresses.

Pecoy project highlights:

• Large copper system with an inferred mineral resource of 865 million tonnes at 0.34 per cent copper (approximately 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 (approximately 1,650 metres) with year-round access and proximity to infrastructure corridors and deepwater ports;
• Additional district-scale upside at Tororume (approximately eight kilometres north), where all nine historical drill holes intersected mineralization;
• The first two initial holes drilled by the company in the South Breccia have returned the following headline numbers:
  • PEC25-065 intersected 1,014.0 metres of 0.37 per cent copper and 0.13 gram per tonne gold from 17 metres;
  • PEC25-066 intersected 1,020.5 metres of 0.43 per cent copper and 0.09 gram per tonne gold from 48 metres.

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 copper, 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 with 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.
