District Identifies Large and Robust Targets from Airborne MobileMT Survey at Malgomaj Alum Shale Property in SwedenVancouver, British Columbia--(Newsfile Corp. - December 2, 2025) - District Metals Corp. (TSXV: DMX) (Nasdaq First North: DMXSE SDB) (OTCQX: DMXCF) (FSE: DFPP); ("District" or the "Company") is pleased to announce positive results from the airborne Mobile Magnetotelluric ("MobileMT") survey conducted over its 100%-owned Malgomaj mineral licenses, located in Västerbotten County, north-central Sweden (Figures 1 to 3). On the basis of these encouraging results, the Company has filed an application for a new mineral license adjacent to the Company's existing Malgomaj mineral license nr 1003, that covers potential extensions of the MobileMT anomaly.Together with the Österkälen and Tåsjö licenses, Malgomaj forms part of the Company's Alum Shale Properties, collectively covering approximately 79,250 hectares. All three license areas were surveyed using MobileMT during the summer of 2025. The survey generated extensive datasets and identified numerous geophysical anomalies. The results have been detailed in a series of three news releases - this being the final installment.The Company's Malgomaj mineral licenses are approximately 177 km to 217 km northeast from the Company's 100% owned Viken Property, which hosts the Viken Energy Metals Deposit.The high resolution MobileMT survey results, covering approximately 37,132 hectares at the Malgomaj mineral licenses nr 1001 to 1003 have successfully outlined six low resistivity (highly conductive) anomalies (Target Areas A to F in Figure 1) consistent with the MobileMT signature observed at the Company's Viken Deposit as reported in District's news release of September 24, 2025. These two target areas show size and scale that surpasses the MobileMT conductive anomalies observed at the Viken Property:Target A: 20.4 km long by up to 5.4 km wide low resistivity (highly conductive) anomaly that is interpreted to be Alum Shale.Target B: 17.7 km long by up to 4.1 km wide low resistivity (highly conductive) anomaly that is interpreted to be Alum Shale.These results represent a major step forward in District's strategy to delineate drill-ready targets within a largely underexplored region characterized by Alum Shales enriched in vanadium, potash, uranium, molybdenum, nickel, zinc, copper, and rare earth elements (REEs).The Viken Deposit contains the largest undeveloped Mineral Resource Estimate of uranium in the worldi along with significant Mineral Resource Estimates of vanadium, molybdenum, nickel, copper, zinc, and other important and critical raw materials as reported in District's news release from April 29, 2025.The MobileMT survey covered approximately 1,255 line kilometers at 400-meter line spacing across the Malgomaj Property. The high-priority target areas were selected based on the shallow depth and thickness of the interpreted Alum Shale. The Alum Shale is typically flat-lying, and is rich in graphite and sulphides, making it low resistivity (highly conductive) and easy to detect using the airborne MobileMT system.Garrett Ainsworth, CEO of District, commented: "Our technical team, in collaboration with Convolutions Geoscience, have now completed a thorough review on all of the MobileMT data from our extensive Spring-Summer 2025 campaign flown by Expert Geophysics, and I can say that the MobileMT survey at our Malgomaj mineral licenses has delivered an exceptional outcome. The newly defined MobileMT conductive anomalies at Malgomaj are both large and strong - attributes that likely indicate the presence of thick, mineralized Alum Shales with the potential to host significant uranium and associated important and critical raw materials. The clarity with which these anomalies present combined with their favorable structural context, provides a high level of technical confidence, and marks a major step forward in our understanding of this underexplored district.These findings reinforce our previous view that Malgomaj represents a highly prospective opportunity for a scalable Alum Shale discovery. We are adding to our current mineral license holdings adjacent to Malgomaj mineral license 1003 to ensure that we capture the full continuity of these priority targets."Uranium is commonly used as a geochemical pathfinder in mineral exploration due to its close association with various valuable mineral deposits, including rare earth elements, base metals, and iron-oxide-copper-gold (IOCG) systems. In Sweden, certain geological environments show elevated uranium concentrations that may indicate the presence of other economically significant metals and minerals. On November 5, 2025 the Swedish Government approved the Proposal to lift the ban on uranium exploration and mining (see news release dated November 5, 2025), and the associated Legislation is expected to be revised accordingly on January 1, 2026.Figure 1: Malgomaj Property MobileMT Survey Results in Plan ViewTo
