## 📌 Key Highlights
- **Australia** dominates the list with over 1.67 million tonnes, accounting for roughly **25% of global reserves**.
- **Kazakhstan** and **Canada** rank 2nd and 3rd, reinforcing their status as major uranium producers.
- **Russia** and **China** also feature in the top 10, giving them significant leverage in nuclear fuel supply chains.
- The **United States** ranks only 13th, with relatively modest reserves compared to its nuclear energy capacity.
- Several **African nations** (Namibia, Niger, South Africa, Botswana, Tanzania, Mauritania) appear on the list, highlighting the continent's growing strategic importance in uranium mining.

## 💡 Strategic Implications
Uranium is the core fuel for nuclear power generation, making it a critical resource for energy security and low-carbon transition strategies.
Countries with large reserves hold substantial bargaining power in global energy markets. In particular, the **top three nations (Australia, Kazakhstan, and Canada)** together account for nearly half of the world's identified recoverable uranium, meaning their mining policies and export regulations will heavily influence global supply and pricing in the coming years.
