Ukraine is home to 5% of the world’s critical mineral wealth, including 22 of the 34 minerals identified by the European Union as vital for defence, construction and high-tech manufacturing. However, there’s a big difference between resources — what’s in the ground — and reserves — what can be commercially exploited. Ukraine’s proven mineral reserves are limited. Further, Ukraine has an estimated mineral wealth of around US$14.8 trillion, but more than half of this is in territories currently occupied by Russia.
