TD: "LYC up 7-8 folds plus by 2022", page-63

Gareth's TMR probably best resource:

"The TMR Advanced Rare-Earth Projects Index consists of rare-earth projects currently underway around the world, which have been formally defined as a mineral resource or reserve, under the guidelines of a relevant scheme such as NI 43-101, the JORC Code or the SAMREC Code. This includes projects that are not required to produce such estimates to these guidelines (such as those owned by private companies), but which have reported adherence to the technical report format prescribed by one of these schemes."

Pretty much a given these assets locked down, but only covers ROW, and pricing dated:
