District Commences UAV Radiometric and Magnetic Survey at Uranium Polymetallic Properties in Sweden

Vancouver, British Columbia--(Newsfile Corp. - July 22, 2025) - District Metals Corp. (TSXV: DMX) (Nasdaq First North: DMXSE SDB) (OTCQB: DMXCF) (FSE: DFPP); ("District" or the "Company") is pleased to announce that MWH Geo-Surveys International Inc. ("MWH") has been retained to conduct a detailed Unmanned Aerial Vehicle ("UAV") radiometric and magnetic survey at the Ardnasvarre, Sågtjärn, and Nianfors Properties (Figures 1 to 3) located in Norrbottens, Jämtland, Västernorrland, and Gävleborgs Counties, Sweden.

Garrett Ainsworth, CEO of District, commented: "Much of the Ardnasvarre, Sågtjärn, and Nianfors Properties are covered by a thin veneer of glacial overburden, which has never seen a detailed radiometric or magnetic survey. The UAV will fly relatively low to the ground with a tight line spacing of 25 or 50 m that will give us very detailed data allowing us to see subtle radiometric and magnetic anomalies.

"The radiometric data from this survey will help identify uranium-rich areas for further exploration on the ground that could include prospecting, mapping, and sampling. The Ardnasvarre, Sågtjärn, and Nianfors properties all contain uranium mineralized zones in bedrock that are associated with magnetic highs. The detailed magnetic data will reveal the extent of known uranium zones and potentially identify new targets.

"The optimal target generated from this UAV survey will be a magnetic high anomaly with an associated uraniferous radiometric "boulder train" that trends towards the south to southeast, which was the dominant direction of the most recent glaciation."

The UAV radiometric and magnetic survey will be flown east to west at 25 to 50 m line spacing of approximately 1,942-, 755-, and 520-line kilometers over the Ardnasvarre, Sågtjärn, and Nianfors Properties, respectively. Radiometric data will be collected with a D230A Gamma-Ray Spectrometer, which measures dose rate, total gamma radiation, and energy windows for potassium, uranium, thorium, and various man-made radionuclides. This is expected to identify potential near-surface uranium anomalies that will be pinpointed for follow up on the ground. The magnetic data will be collected by a Geometrics MagArrow laser pumped Cesium vapor magnetometer, which is well suited for the terrain in Sweden.

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 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 world¹ 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.

For further information on the Tomtebo Property, please see the technical report entitled "NI 43-101 Update Technical Report on the Tomtebo Project, Bergslagen Region of Sweden" dated effective October 15, 2020 and amended and restated on February 26, 2021, which is available on SEDAR+ at .
