Ann: Bankable Feasibility Study Update, page-56

If the whole REE market is shot then you really should quit it.
Neodymium/Praseodymium is important for the EV industry as a key component in electric motors, Zirconium is used in the nuclear power industry, Ce, Ga and Nd are important in electronics and are used in the production of LCD and plasma screens, fibre optics, lasers, as well as in medical imaging. In fact REEs are increasingly important for modern technology and so are being categorised as strategic elements by Western governments.
Somehow, I cannot see the REE sector as being "shot", even if finance for development has become harder, along with everything else at present.
As for Ndualla being remote, that is the least of issues. Already PEK has funded the construction of a new road into the area and it only has to connect with established roading and thence to a port. Many mines operate in more difficult environments.
