NEWS RELEASE
District Copper To Advance Copper Keg Porphyry Project Toward First-Ever Drill Program in British
Columbia’s Guichon Creek Batholith
Vancouver, British Columbia: March 2 5, 2026: District Copper Corp. ( TSXV: DCOP) (“District Copper”,
“District”, or the “Company”) is pleased to announce its 2026 exploration plans for its flagship Copper Keg
porphyry copper project, covering 6,628 hectares of favourable geology at the northern end of the Guichon
Creek batholith in ce ntral British Columbia. It is anticipated that the work program will lead to the
identification of high priority drill targets.
Proposed 2026 exploration program
The results of the 2025 exploration program were outlined in a news release dated October 16, 2025. The
2026 program is designed to build on these results and advance the project to the drill -permit application
stage. The planned work consists of:
a) a deep-penetrating DCIP geophysical survey covering a total of 14.5 line-km over Targets #1 and #2
to delineate the open -ended chargeability anomaly identified in 2021, scheduled for late Q2/Q3
2026;
b) detailed geological mapping of the planned geophysical lines, rock sampling for whole rock and trace
element geochemistry to better interpret the results of the geophysical survey, scheduled to
commence when snow conditions permit;
c) petrographic studies on select rock samples to refine the alteration model and better define
intrusive phases of the Guichon Creek batholith on the property;
d) submission of a Notice of Work in Q3 2026 to conduct a drilling program following receipt of
geophysical survey results; and
e) drill testing of the buried chargeability anomaly underlying the two porphyry targets identified in
2025, on receipt of the permits required to conduct drilling operations.
Geological context
The Guichon Creek batholith hosts the porphyry copper deposits in the Highland Valley Copper (“HVC”)
district, located approximately 20 km south of Copper Keg. Teck Resources’ HVC operation is Canada’s
largest open-pit copper mine, producing an average of 132,000 tonnes of copper annually, and is currently
undergoing a $2.1 to $2.4 billion mine life extension to sustain production through 2046. The Copper Keg
property is also situated approximately 20 km from New Gold’s New Afton copper-gold mine.

Mineralization at neighbouring properties is not necessarily indicative of mineralization on the Copper Keg
property.
Jevin Werbes, CEO, commented: “When I look at this property through the lens of our petrographic and
geochemical data, I see the same Bethsaida-phase intrusive rocks that host the copper deposits at Highland
Valley. Our team identified two target areas whe re the alteration sequence progresses exactly as you’d
expect in an evolving porphyry system: early potassic alteration overprinted by propylitic, then later- stage
phyllic alteration with strong pyrite. Combined with the buried chargeability anomalies, the intrusive
breccias, and the surface copper and molybdenum geochemistry, these targets present a compelling case
for drill testing. As we move toward defining high-impact drill targets, our goal is to build the technical case
that earns us a drill permit on this property for the first time. The 14.5 km DCIP survey is the gating step.
Once we have that data integrated with our geological mapping and petrographic work, we expect to be in
a position to submit a Notice of Work and transition Copper Keg from an exploration project to a drill-ready
asset.”
Project Highlights
• Two buried porphyry copper targets identified at the northern end of the Guichon Creek batholith,
the same intrusive complex that hosts Teck’s Highland Valley Copper mine 20 km to the south
• 14.5 line-km DCIP geophysical survey planned to delineate open-ended chargeability anomaly first
identified in 2021
• Target #1 : Open -ended, east -dipping buried chargeability and low -resistivity anomaly with soil
copper values exceeding 100 ppm and secondary copper mineralization in phyllic -altered biotite
granodiorite
• Target #2: 600m x 400m gossan zone with three stages of cross -cutting dike intrusions, intrusive
breccias, chalcopyrite mineralization, and elevated molybdenum (up to 17.4 ppm)
• Petrographic and geochemical work confirms intrusive rocks at Copper Keg exhibit characteristics
of the Bethsaida phase of the Guichon Creek batholith, the principal host to Highland Valley’s
copper deposits
• 2026 program designed to advance the project to drill-permit submission stage for the first time in
the property’s history
Priority Exploration Targets
A brief description of the two porphyry targets that will be the focus of the 2026 exploration plan on the
Copper Keg porphyry copper project is provided below:
Target #1:
Target #1 hosts a buried geophysical anomaly that, in porphyry copper systems, is typically associated with
sulphide mineralization at depth.
This target is in the Guichon Creek intrusive located on the northeast side of the project and covers an open-
ended, east-dipping buried positive chargeability and low resistivity anomaly. Reconnaissance-style mapping
in this area located several exposures of secondary copper mineralization hosted in phyllic -altered biotite
granodiorite and several intrusives that exhibit petrographic and geochemical similarities to the Bethsaida
phase of the Guichon Creek batholith. Soil geochemical surveys have outlined s everal areas of anomalous
3
copper concentration (>100 ppm) that overlie the positive chargeability anomaly.
Target #2:
Target #2 hosts the largest surface expression of mineralization on the property: a gossan zone measuring
600 m by 400 m with visible copper and elevated molybdenum, both key pathfinder elements in porphyry
copper systems.
This target is in the north-central portion of the property, underlain by an interpreted thin veneer of phyllic
and propylitic altered silicified basaltic and andesitic volcanics overlying the Guichon Creek intrusive at
depth. The eastern side of this targ et is characterized by a large gossan zone that measures approximately
600 m long by up to 400 m wide that exhibits three stages of cross-cutting late-stage dike intrusive activity,
several intrusive breccias and sporadic secondary and trace primary (chalc opyrite) copper mineralization.
Several samples of intrusive breccia and extensively altered rock of uncertain origin (based on petrographic
description) from this target contain elevated molybdenum concentrations (up to 17.4 ppm) associated with
copper mineralization.
