District Metals (DMX) Corporate presentation summary

Strategic focus and jurisdiction

• Holds 100% ownership of the Viken Deposit, the world's largest undeveloped uranium deposit, also rich in vanadium and other critical raw materials.

• Portfolio includes four additional advanced-stage uranium polymetallic properties in Sweden: Sågtjärn, Nianfors, Ardnasvarre, and Alum Shale Properties, all with historic drilling and resource estimates.

• Operates in Sweden, a top mining jurisdiction with a long mining history, low corporate tax, and strong government and public support for mining and energy security.

• Sweden recently lifted its moratorium on uranium mining and exploration, aligning with a national shift to pro-nuclear energy policy.

Viken Deposit and exploration potential

• Viken Deposit contains an inferred mineral resource of 4.33 billion tonnes at 161 ppm U3O8, totaling 15 billion pounds U3O8, plus significant vanadium, molybdenum, nickel, copper, zinc, and rare earth elements.

• MobileMT geophysical survey identified nine new target areas outside the current Viken Deposit, with three showing stronger conductive responses than the deposit itself.

• Updated mineral resource estimate and airborne geophysical survey completed in 2025; preliminary economic assessment (PEA) and economic impact study (EIS) planned for 2026.

Additional uranium properties

• Sågtjärn Uranium Property: Historical inferred resource of 756,000 tonnes at 0.068% U3O8 (1.14 million lbs), open in all directions, with no modern systematic exploration.

• Nianfors Uranium Property: Majsaberget occurrence hosts at least 13 million lbs U3O8 at 0.07–0.14% U3O8, based on historical boulder sampling and estimates.

• Ardnasvarre Uranium Property: Labbas Zone has a historical resource of 86,478 tonnes at 0.12% U3O8 (228,780 lbs), with mineralization open in all directions.

• Alum Shale Properties: Tåsjö Field historically estimated to host 75–150 million tonnes at 0.03–0.07% U3O8, 0.11–0.24% REE, and 3.75–7.5% phosphate.
