Vancouver, British Columbia--(Newsfile Corp. - October 29, 2025) - District Metals Corp. (TSXV: DMX) (Nasdaq First North: DMXSE SDB) (OTCQB: 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 Österkälen mineral license, located in Jämtland County, north-central Sweden.
On the basis of these encouraging results, the Company has filed an application for a new mineral license adjacent to the northwest of the Österkälen nr 101 mineral license that covers the extension of the MobileMT anomaly.
The Österkälen, Tåsjö, and Malgomaj licenses together form 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 produced extensive datasets and identified numerous geophysical anomalies, the findings of which will be presented across three separate news releases - beginning with this one.
The Company's Österkälen mineral license is approximately 100 km northeast from the Company's 100% owned Viken Property, which hosts the Viken Energy Metals Deposit.
Highlights:
- MobileMT results have identified an 8 km long by up to 3.5 km wide low resistivity (highly conductive) anomaly that is interpreted to be Alum Shale.
- The high-resolution MobileMT survey results (see Figures 1 and 2), covering approximately 7,800 hectares at the Österkälen nr 101 mineral license have successfully outlined a strong and laterally extensive low resistivity (highly conductive) anomaly consistent with the MobileMT signature observed at the Company's Viken Deposit as reported in District's news release of September 24, 2025.
These findings are a significant advancement in District's strategy to define drill-ready targets within a vastly underexplored region known for its Alum Shales that contain important and critical metals and minerals.
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 291 line kilometers at 400-meter line spacing across the Österkälen Property. The high-priority target area was 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: "The MobileMT survey results from our Österkälen Property are highly encouraging, and reveal a strong and large conductive anomaly that aligns with the interpreted Alum Shale horizon. This supports our geological model and corporate strategy, and highlights the significant potential to host Alum Shale with important and critical raw materials.
With these results, we are not only confirming the presence of a potentially high tonnage Alum Shale target, but also advancing toward our goal of building a uranium polymetallic portfolio of district-scale assets in Sweden capable of delivering meaningful value to our shareholders and stakeholders. The combination of a large, coherent geophysical anomaly, strong geological support, and proximity to infrastructure ranks Österkälen as one of our most compelling growth opportunities to date outside of our Viken Property."
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. However, while uranium anomalies can guide exploration efforts, it is important to note that there is currently a moratorium on uranium exploration and mining in Sweden that the Government has stated they intend to abolish as of January 1, 2026 (see news release dated September 2, 2025).

About District Metals Corp.
District Metals Corp. is led by industry professionals with a track record of success in the mining industry. The Company's mandate is to seek out, explore, and develop prospective mineral properties through a disciplined science-based approach to create shareholder value and benefit other stakeholders. District is a 2025 TSX Venture 50 company, ranking among the top-performing issuers on the TSX Venture Exchange in the past year.
District is a polymetallic exploration and development company focused on the Viken and Tomtebo Properties in Sweden. The Viken Property covers 100% of the Viken Energy Metals Deposit, which 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.
The advanced exploration stage Tomtebo Property is located in the Bergslagen Mining District of south-central Sweden and is situated between the historic Falun Mine and Boliden's Garpenberg Mine that are located 25 km to the northwest and southeast, respectively. Two historic polymetallic mines and numerous polymetallic showings are located on the Tomtebo Property along an approximate 17 km trend that exhibits similar geology, structure, alteration and VMS/SedEx style mineralization as other significant mines within the district.
