District Copper Presents Integrated Geological Framework for Copper Keg Porphyry Copper Targets Ahead of DCIP Survey
District Copper Corp. (DCOP) has released an integrated geological interpretation of its Copper Keg project, identifying two priority porphyry copper targets based on four years of exploration data from 2021 to 2025. The company announced a planned DCIP geophysical survey scheduled to commence on or about August 26, 2026, aimed at resolving the geometry of these targets and defining drill sites for its first-ever diamond drill program. The release highlights the convergence of geological, geochemical, and geophysical indicators at two specific targets: a buried chargeability anomaly (Target #1) and a gossan zone with potassic alteration (Target #2).
The company’s integrated geological model synthesizes four years of data including DCIP geophysics, high-sensitivity airborne magnetics and radiometrics, soil and rock geochemistry, geological mapping, and petrographic studies. The planned DCIP survey will be operated by Quantec Geoscience using a Titan DCIP system. The 14.5 line-km survey is anticipated to be completed in Q3 2026, subject to wildfire conditions. Its objectives include delineating the lateral and vertical extent of the open-ended chargeability anomaly at Target #1, determining if a chargeability anomaly exists beneath the potassic-altered gossan zone at Target #2, and providing subsurface data to define drill targets and support a Notice of Work application.
Target #1 is located on the northeast side within the Guichon Creek intrusive. It was identified in 2021 as an open-ended, east-dipping positive chargeability and low-resistivity anomaly. Surface indicators include secondary copper mineralization in phyllic-altered biotite granodiorite, with soil geochemistry showing copper anomalies greater than 100 ppm coincident with the anomaly. Petrographic analysis indicates that samples match the Bethsaida phase of the Guichon Creek batholith, which is the principal host to Highland Valley deposits.
Target #2 is located in the north-central property, underlain by phyllic and propylitic altered Nicola volcanics overlying the Guichon Creek intrusive. The eastern portion features a gossan zone approximately 600m long by up to 400m wide. Mineralogy includes cross-cutting dike intrusions, intrusive breccias, chalcopyrite, pyrite (up to approximately 10%), muscovite, magnetite, actinolite, prehnite, epidote, and tourmaline. Geochemistry shows elevated molybdenum up to 17.4 ppm associated with copper mineralization. The strongest potassic alteration observed on the property suggests the core of a porphyry system may be at shallow depth. A second similar gossan zone exists approximately 600m to the west but has not been explored.
Previous survey context from 2021 covered 5 lines totaling 19.3 line-km using a Quantec Titan-120 with a dipole-dipole array, 200m spacing, and approximately 600m depth of investigation. While this identified multiple targets, coverage was insufficient to define full geometry. The project is situated in the Guichon Creek batholith, which hosts major porphyry copper deposits. Teck Resources' Highland Valley Copper mine is located approximately 20km to the south and is undergoing a $2.1-2.4B extension through 2046. Neighbor Getty Copper Inc. reported initial drill results of 342m of 0.50% Cu from 9m depth in June 2026.
Next steps include submitting a Notice of Work in Q3 2026. The plan for the first diamond drill program is dependent on survey results, permitting, and financing. Chris M. Healey, P.Geo., Chief Geologist and Director, serves as the Qualified Person.
Jevin Werbes, CEO, stated: "This release is intended to show investors how four years of systematic work fit together into a single geological model. Each dataset, the IP geophysics, the airborne magnetics, the soil geochemistry, the petrographic studies, tells us something about a different part of the system. What they tell us collectively is that Copper Keg hosts the alteration sequence, the intrusive phases, the surface geochemistry and the geophysical signature you would expect to see above a buried porphyry copper system within the Guichon Creek batholith."
