High Priority Targets From Survey At Tasjo Alum Shale Property

VANCOUVER – District Metals Corp. reported positive results from the airborne Mobile Magnetotelluric (MobileMT) survey conducted over its Tåsjö nr 101 to 108 mineral licenses, located in Jämtland and Västerbotten Counties, north-central Sweden. On the basis of these encouraging results, the Company has filed several applications for new mineral licenses adjacent to some of the Tåsjö mineral licenses that cover possible extensions of MobileMT anomalies.

Together with the Österkälen and Malgomaj mineral licenses, the Tåsjö mineral licenses form 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 revealed numerous geophysical anomalies.

The Company’s Tåsjö mineral licenses are approximately 133 km to 170 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 34,300 hectares at the Tåsjö mineral licenses nr 101 to 108 has successfully outlined eight low resistivity (highly conductive) anomalies (Target Areas A to H) consistent with the MobileMT signature observed at the Company’s Viken Deposit. 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, potash, molybdenum, nickel, copper, zinc, and other important and critical raw materials.

The MobileMT survey covered approximately 1,391 line kilometers at 400-meter line spacing across the Tåsjö 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.
