Strategic focus and project overview

• Shifted focus to uranium in 2022 following Sweden's pro-nuclear policy changes, including lifting the uranium mining ban effective January 1, 2026.

• Flagship Viken project is the world's largest undeveloped uranium deposit, also rich in vanadium, potash, and other critical minerals.

• Owns 100% of Viken with no royalties, and maintains a clean share structure with no debt and strong institutional and insider ownership.

• Assembled an experienced technical and advisory team with deep expertise in geology, mining, and Swedish regulatory processes.

Economic assessment and impact

• Preliminary Economic Assessment (PEA) released June 2026 shows after-tax NPV of $2.9 billion, IRR of 46%, and payback in 2.1 years.

• Projected after-tax free cash flow of $531 million per year and operating margin of 145%.

• Initial CapEx just under $900 million, with a 13-year mine life based on only 3% of the resource, indicating significant expansion potential.

• Economic impact study estimates $7.6 billion total contribution over mine life, including $1.6 billion in corporate taxes and $22 million to landowners.

Exploration and development plans

• MobileMT survey identified nine new target areas, three larger than the current Viken deposit, with drilling planned for later this year.

• Ongoing drilling at alum shale projects Österkällen and Malmgruvan, with results expected in Q3 and Q4.

• Land package for alum shales doubled in late 2025, targeting additional Viken-like deposits.

• Fieldwork and airborne surveys continue at other properties, with further results and updates anticipated in Q4.
