NEWS RELEASE

Further to District Copper Corp.'s news release dated Sept. 14, 2026, the company advises that the agreement to acquire mineral claim 1137534, a 368.4-hectare property situated adjacent to the Copper Keg project area, was entered into with Jeff Poloni, an arm's-length party. Additionally, the shares issued in connection with the acquisition has a deemed value of 9.5 cents per share.

About Copper Keg

The Copper Keg project comprises 23 claims totalling 6,525.83 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 B.C. Minister of Mines Annual Report for 1898 documented a "spectacular gossan" several kilometres long, located approximately nine kilometres from Ashcroft, B.C., 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.

District Copper has carried out four years of systematic exploration between 2021 and 2025, including DCIP geophysics, high-sensitivity airborne magnetics and radiometrics, soil and rock geochemistry, detailed geological mapping, and petrographic and whole rock geochemical studies. A comprehensive review of the full data package was presented in the company's news release dated Aug. 19, 2026, the first integrated geological model relating these data sets to one another and explaining the rationale for the current DCIP survey design.

The company's DCIP geophysical survey, conducted by Quantec Geoscience using its Titan DCIP system, is schedulled to commence at the end of September, 2026, and is designed to delineate drill targets for the property's first-ever diamond drill program.

Resurgence of activity in the 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, approximately 20 kilometres to the south, is Canada's largest copper mine and received a $2.1-billion to $2.4-billion mine life extension approval to continue operations through 2046. The government of Canada has committed $50-million in conditional funding to upgrade B.C. Hydro's regional transmission system in support of the Highland Valley expansion.

Getty Copper Inc. (TSX-V: GTC), whose Getty project is located in the Highland Valley district directly between Copper Keg and Teck's operation, recently reported initial drill results from Getty South including 68.5 metres of 0.81 per cent Cu from 39.5 m depth and 184 m of 0.37 per cent Cu, with mineralization extended 72 m below historical intercepts and remaining open within a broader IP geophysical anomaly.

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.
