Swedish uranium and energy metals landscape

• Sweden is shifting to pro-nuclear policies, with government support for nuclear power and a process underway to lift the uranium mining moratorium imposed in 2018.

• Six operating nuclear reactors supply about 29% of Sweden's electricity; government is considering restarting reactors and building new ones.

• Legislative process to lift the uranium ban is advancing, with a proposal expected to reach parliament in H2 2026.

• Sweden hosts significant uranium deposits, including the Viken Energy Metals Deposit.

Viken deposit and uranium portfolio

• Viken Deposit in Jämtland County is the world's largest undeveloped uranium deposit, with updated 2025 resource estimate: 456M tonnes inferred at 161 ppm U3O8 (15B lbs U3O8), 175M tonnes indicated at 176 ppm U3O8.

• Mining of Viken is possible under current law, but uranium recovery is restricted until the moratorium is lifted.

• Additional uranium properties: Sågtjärn (historical inferred resource: 756,000 tonnes at 0.068% U3O8), Nianfors (Majsaberget occurrence: at least 12.9M lbs U3O8), Ardnasvarre (Labbas zone: 86,478 tonnes at 0.12% U3O8), and Alum Shale properties (Tåsjö field: 75–150M tonnes at 0.03–0.07% U3O8, 0.11–0.24% REE).

• Most uranium properties have not seen systematic modern exploration; historical estimates are not current NI 43-101 resources.
