From this Announcement you get a feel for the Timeline:
Energy Fuels has commenced producing heavy rare earth element oxides at its White Mesa Mill at pilot scale, and could be in a position to produce separated heavy rare earth oxides on a commercial...

Energy Fuels is now in the process of producing Dysprosium („Dy“) oxide, at a minimum purity of 99.5% and potentially exceeding 99.9% purity, at pilot scale at its White Mesa Mill in Utah (the "Mill"

. Energy Fuels expects to complete production of its first kilogram (kg) of Dy oxide within the next 30 days.
This was achieved now
The Company expects to continue producing Dy oxide on a pilot scale until the end of September 2025, at which time it expects to have produced approximately 15 kg of Dy., generating enough residuals to feed its Terbium („Tb“) circuit starting the beginning of October 2025. The Company expects to have produced one kg of Tb on a pilot scale by the end of November 2025. If progress continues as planned, the Company expects to be able to start producing samarium („Sm“) oxide on a pilot scale at the Mill in January of 2026.
With the Donald Project from Australia you would have these no.
Donald Project contains approximately 3.02% Sm, 0.37% Tb and 2.15% Dy on a 100% total rare earth oxides (TREO) basis
At the average Phase 1 production rate at the Donald Project of 7,100 tonnes of REEC per year, the REEC would contain 129 tonnes of Sm, 16 tonnes of Tb and 92 tonnes of Dy per year for the next 40+ years, representing 250%, 23% and 34% respectively of current annual U.S.
In addition there would be the NdPr.
