This table comes from the Lynas Website.

The CLD or Central Lanthanide Deposit is being mined and processed now. The Duncan Deposit contains a greater proportion of the heavy rare earths but as you can see by the table, most of this deposit also consists of lower value Cerium and Lanthanum. Processing the Duncan Deposit requires a completely different chemistry. Exploiting this deposit is a best several years away IMO.
