District Copper contracts Quantec Geoscience for DCIP survey at Copper Keg

Deep penetrating geophysical survey designed to delineate drill targets on a property with 130 years of documented copper mineralization that has never been tested by modern drilling Vancouver, British Columbia--(Newsfile Corp. - June 23, 2026) - District Copper Corp. (TSXV: DCOP) (OTCID: CAXPF) ("District Copper," "District," or the "Company") is pleased to announce that it has received approval from the BC Ministry of Mining and Critical Minerals to proceed with a deep penetrating DCIP (DC Induced Polarization) geophysical survey on its 100%-owned Copper Keg porphyry copper project in the Kamloops Mining Division, British Columbia. The Company has contracted Quantec Geoscience to complete the survey using its Titan DCIP system. The field program is anticipated to be completed in Q3 2026.

Management Commentary Jevin Werbes, CEO, commented: "Receiving permit approval and contracting Quantec to mobilize represents the most significant milestone in Copper Keg's history. Our 2025 mineralogical work confirmed what we have long suspected: that the alteration patterns, intrusive breccias and geochemical signatures at Copper Keg are consistent with a buried porphyry copper system hosted in the same intrusive phases responsible for the deposits at Highland Valley. The upcoming DCIP survey is designed to map the dimensions of that system and define drill targets on a property that has been recognized as prospective since the 1890s but has never been tested by modern drilling.

With Getty Copper actively drilling the same district to our south and Teck investing billions to extend Highland Valley through 2046, the geological and economic case for advancing Copper Keg has never been stronger. We look forward to providing shareholders with results as the program progresses through the summer." Survey objectives The planned survey will cover 14.5 line-km over two priority porphyry copper targets at the northern end of the Copper Keg project. The program is designed to delineate and extend the open-ended chargeability anomaly identified during the Company's 2021 DCIP survey, which was interpreted as one or more deep intrusive bodies underlying the project's extensively altered and mineralized gossan zone.

Mineralogical and petrographic work completed during the 2025 field season confirmed the presence of potassic, propylitic and phyllic alteration assemblages, intrusive breccias, and multiple phases of high-temperature hydrothermal activity consistent with a buried porphyry copper system at depth.[2] Whole rock and trace element geochemistry identified outcrops exhibiting geochemical signatures matching the Bethsaida and Skeena intrusive phases of the Guichon Creek batholith, the same late-stage intrusives that host the porphyry copper deposits at Teck Resources' Highland Valley Copper operation approximately 20 km to the south. The integration of the DCIP survey results with the Company's existing geological, geochemical and geophysical datasets will form the basis for drill target definition and the commencement of the drill permitting process, advancing Copper Keg toward its first-ever diamond drill program. About Copper Keg The Copper Keg project comprises 22 claims totaling 6,158 hectares at the northern end of the Guichon Creek batholith, the same intrusive complex that hosts every major porphyry copper deposit in the Highland Valley district.

The project benefits from excellent infrastructure with power, gas and rail access, located within the Kamloops Mining Division, a few hours' drive from the regional centre of Kelowna. Historical exploration at Copper Keg dates back to the late 1800s. The BC Minister of Mines Annual Report for 1898 documented a "spectacular gossan" several kilometres long, located approximately 9 kilometres from Ashcroft, BC, describing "a large body of ore, carrying gold and silver, but principally copper," where a 24-metre adit was driven into the mineralized zone.

Despite this early recognition, subsequent exploration was limited and superficial in nature, and the property has never been tested by modern diamond drilling. From 2021 to 2025, District Copper completed systematic exploration programs including DCIP geophysics, a high-sensitivity airborne magnetometer and radiometric survey, soil sampling, rock sampling, detailed geological mapping, petrographic studies, and whole rock and trace element geochemistry, establishing a comprehensive geological and geophysical database that has progressively strengthened the Company's interpretation of a buried porphyry copper system at depth. Active Highland Valley District The Copper Keg project is located within one of Canada's most active copper exploration and development corridors.

Teck Resources' Highland Valley Copper operation, located approximately 20 km to the south, is Canada's largest copper mine and received a $2.1-2.4 billion mine life extension approval to continue operations through 2046.[1] The Government of Canada has committed $50 million in conditional funding to upgrade BC Hydro's regional transmission system in support of the Highland Valley expansion.[2] Getty Copper Inc. (TSXV: GTC), whose Getty project is located in the Highland Valley district directly between Copper Keg and Teck's operation, is currently conducting the most comprehensive exploration program in the district supporting Highland Valley, with two diamond drill rigs active and over 3,000 metres completed as part of an ongoing 10,000-metre program targeting resource expansion at its Getty North and Getty South deposits.[3] Getty Copper has stated that it controls approximately 25 per cent of the Highland Valley copper district. Tower Resources Ltd. (TSXV: TWR) continues active exploration at its Rabbit North property between the Highland Valley and New Afton mines, reporting significant gold and copper-gold drill results from the same Kamloops porphyry copper district.[4] British Columbia's mineral exploration sector posted record spending of $751 million in 2025, with copper overtaking gold as the province's top exploration target for the first time on record.[5] Qualified Person Chris M.
