District Metals (DMX) investor relations material

Strategic focus and assets

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

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

• Sweden lifted its moratorium on uranium mining in November 2025, aligning with a pro-nuclear energy policy and plans for new reactors.

Viken Deposit and exploration

• Viken Deposit has an inferred mineral resource of 4.33 billion tonnes at 161 ppm U3O8, containing 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.

Other Swedish uranium properties

• Sågtjärn: 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: Majsaberget occurrence hosts at least 13 million lbs U3O8 at 0.07–0.14% U3O8, based on mineralized boulders; no systematic modern exploration.

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

• Alum Shale Properties: Tåsjö area 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.
