District Copper Announces 2026 Field Program to Advance Copper Keg Porphyry Copper Project to Drill Stage and Closes First Tranche of Private Placement

Vancouver, British Columbia--(Newsfile Corp. - November 18, 2025) - District Copper Corp. (TSXV: DCOP) ("District Copper", "District", or the "Company") is pleased to provide an update on results of the 2025 field program and planned exploration activities for its flagship Copper Keg porphyry copper project in the Kamloops mining Division, BC. The project covers 6,628 ha located at the northern end of the Guichon batholith, approximately 20 kms north of the porphyry copper deposits in the Highland Valley Copper ("HVC") district currently being mined by Teck Resources Limited. Highlights of the updated exploration model are outlined below.

Highlights:

• Whole rock, trace element geochemistry and petrographic studies have identified several outcrops that exhibit petrographic and geochemical characteristics of the Skeena and Bethsaida intrusive phases of the Guichon Creek intrusive that hosts the porphyry copper deposits in the HVC.
• The Nicola volcanics and Guichon Creek intrusive in the northern portion of the project exhibit the alteration patterns typically observed in a porphyry copper system consisting of early stage potassic over printed by propylitic followed by a later stage of strong to intense phyllic alteration accompanied by strong pyrite mineralization.
• Outcrops of the Nicola Volcanics exhibit the strongest potassic alteration suggesting a buried porphyry system at depth.
• Three outcrops of intrusive breccia combined with petrographic evidence of several phases of high temperature hydrothermal activity suggests the presence of a porphyry copper system at depth.
• Widespread fracture, quartz veinlets, blebs of pyrite +/- trace chalcopyrite mineralization occur in the Nicola Volcanics and in several outcrop of the Guichon Creek intrusive.
• The presence of quartz, epidote, anhydrite and magnetite veins and veinlets in the Nicola Volcanics at the northern end of the project support the interpretation of a buried porphyry at depth.

Jevin Werbes, CEO, commented, "Our systematic approach to the 2025 field season has significantly upgraded the porphyry copper potential of the property and identified two target areas located at the northern end of the project exhibiting the geological, alteration and geophysical signatures that suggest the presence of a buried porphyry copper system. These targets host two large gossanous areas, an area of intense porphyry style alteration, a buried positive chargeability anomaly, magmatic hydrothermal breccia and sporadic copper mineralization of which several samples contain elevated molybdenum concentrations. The objective of the proposed 2026 program is to prepare the project to transition to the drilling stage."
