NEWS RELEASE

DISTRICT COPPER COMMENCES SUMMER FIELD PROGRAM AT COPPER KEG

Vancouver, B.C. May 15, 2025 – District Copper Corp. (“District C opper”, “District”, or the “Company”)

(TSX-Venture: DCOP) is pleased to announce that crews have mobilized and field work is underway on its

flagship Copper Keg porphyry copper project in the Kamloops mining Division, BC. The project covers 6628

ha and is located at the northern end of the Guichon batholith, approximately 20 kms north of the porphyry

copper deposits currently being mined by Teck Resources Limited.

The 2025 program is planned as a multi- phase program with its initial objective to complete a preliminary

reconnaissance of the entire project area collecting detailed data on features that characterize the porphyry

copper deposit in the Highland Valley mining district. Phase 1 of the planned program focuses on

differentiating various intrusive phases of the Guichon Creek Batholith, contact relations with the older

Nicola Volcanics, alteration styles, mineralogical associations and mineralized structures t o prioritize areas

for additional follow-up exploration. The data collected in the initial phase would also be used to complete

a re-interpretation of the results of the airborne and ground geophysical surveys in the context of a porphyry

copper model for the project which sets the basis for Phase 2 of the 2025 exploration program.

Jevin Werbes, CEO, commented “District Copper is excited to get the 2025 exploration program underway.

We are incorporating the historical exploration data into a pragmatic approach for our exploration effort by

establishing an exploration model for Copper Keg based on the porphyry copper deposits in the Highland

Valley. We feel this approach provides a results-based approach to guide the planned exploration in 2025.”

About the Copper Keg property

The following summary of historical exploration has been derived from the publicly available

assessment reports on file with the Ministry of M ines for British Columbia . Historical exploration

spans from the late 1800’s to 2012. The early -stage exploration is reported to consist of mining high

grade copper veins .

The property exhibits the geochemical/alteration/lithologic features typical of the argillic altered

portion of a porphyry copper system at/along the potassic/propylitic contact. The property is

characterized by a large, pyrite bearing, argillic zone exposed along the surface trace of the Barnes

Creek fault, a major NNW trending that crosses the Guichon Creek Batholith. The high -grade copper

veins noted above, reflect supergene enrichment of distal base metal veins typically associated with

a porphyry copper system.

The project is underlain by an intrusive phase of the Guichon Creek batholith which intrude s the

surrounding Nicola Group rocks.

Petrographic work and K/Al: Na/Al ratios indicate an alteration package ranging from argillic -phyllic -

potassic (all alteration phases associated with porphyry copper systems) supported by alteration

minerals indicative of the inner actinolite subzone of a porphyry system as well as secondary biotite

(Potassic alteration) and sericite (phyllic alteration), quartz veinlets with pyrite and chalcopyrite.

A large pyritic zone exhibit s spatial association with the argillic altered zone and could be

representative of what is commonly referred to in porphyry copper terms as the “pyrite shell”.

Chalcopyrite, bornite and malachite (secondary copper carbonate) have been observed in outcrop

and support the presence of a porphyry system.

Two highly altered gossans have been identified along the interpreted trace of the Barnes Creek

fault, a major structure within the Guichon Creek batholith. The first area (800m long by 200m

wide); the second area is 600 m south and smaller in extent. These gossans exhibit erratic copper

concentrations, weak copper -silver soil anomalies and copper minera lization.

Since the Company acquired the property in 2021, it has completed mapping and prospecting, soil

sampling, and ground and airborne geophysical programs. Results from this work are consistent

with the presence of a porphyry copper system.

Soil sampling in 2024 located highly anomalous values on the recently acquired northern claims. Of the

520 samples, 8 returned values >100 ppm Cu (102.0, 122.2, 126.7, 132.2, 134.8, 136.9, 269.1 and 1517.4).

This area is underlain by the Guichon Batholith, which hosts known copper porphyry deposits in this region,

in contact with Nicola volcanics.

in such statements.

In connection with the forward-looking information contained in this news release, District Copper has

made numerous assumptions regarding, among other things: the geological advice that District Copper has

received is reliable and is based upon practices and methodologies which are consistent with industry

standards and the reliability of historical reports. While District Copper considers these assumptions to be

reasonable, these assumptions are inherently subject to significant uncertainties and contingencies.

Additionally, there are known and unknown risk factors which could cause District Copper’s actual results,

performance, or achievements to be materially different from any future results, performance or

achievements expressed or implied by the forward-looking information contained herein. Known risk

factors include, among others: the dimensions and shape of the mineralized areas may not be as estimated;

the targets outlined by the MVI study may not be associated with felsic intrusives porphyry style alteration

or mineralization; the proposed surface program may eliminate these areas as potential targets for future

exploration; the NNW trending structures may not contain indications of magnetite destruction typical of

hydrothermal alteration; u ncertainties relating to interpretation of the outcrop sampling results; the

geology, continuity, and concentration of the mineralization; the financial markets and the overall

economy may deteriorate; the need to obtain additional financing and uncertainty of meeting anticipated

program milestones; and uncertainty as to timely availability of permits and other governmental approvals.
