District Copper Update Exploration Model on Copper Keg Porphyry Copper Project

Core Insights - District Copper Corp. has updated its exploration model for the Copper Keg porphyry copper project, enhancing its potential based on recent geological findings [1][3] Exploration Model Highlights - The project spans 6,628 hectares in the Kamloops mining division, located 20 kilometers north of the Highland Valley Copper district [1] - The 2025 field season identified geological features that significantly enhance the porphyry potential, including later-stage intrusive phases and strong alteration patterns [3][4] - A 14-line kilometer deep penetrating chargeability/resistivity geophysical survey is planned to delineate the dimensions of a positive chargeability anomaly [3] Geological Findings - Phase 1 fieldwork revealed a suite of porphyritic and non-porphyritic Quartz Diorite and Granodiorite phases, hosting three intrusive breccias [4] - Strong geochemical similarities were found between Copper Keg samples and various intrusive phases of the Guichon Creek batholith [5][7] - Alteration patterns typical of porphyry copper systems were identified, including potassic, propylitic, and phyllic alterations [6][10] Mineralization Insights - The gossan zone exhibits limonitic stained quartz-sericite veins with secondary copper mineralization, alongside widespread pyrite mineralization [12] - A total of 23 copper showings have been outlined within the Nicola Volcanics and Guichon Creek intrusive [12] Chargeability/Resistivity Anomaly - An open-ended northeast dipping zone of anomalous chargeability (>10 mrads) was identified, measuring approximately 1,500 meters east-west and 600 to 1,000 meters north-south [13]
