How likely is it that Ukraine's rare earths get developed?
According to geologist Tony Mariano (via Platts), "there are no economically viable rare earth deposits in Ukraine." However, there could be development opportunities, with mining.com citing that tantalum, niobium, and other rare earths could be extracted alongside the Novopoltava phosphate deposit (requiring a $300 mn investment) or the Azov deposit of Rare Earth Metals, but these are both currently outside of the control of Ukraine. President Zelenskyy said that Russia now occupies around half of Ukraine's rare earth deposits, and 40% of its total metal resources.
In our view, the development of rare earth resources in Ukraine would take some time, and will likely require significant investment.
