Obviously the numbers do depend on a lot. I read a post here earlier today taking about China and their control. Prices are high now and will continue to be high as long as China threatens to reduce exports. But, they could easily crush the REE market by producing more... until there are other REE mines, China can control this market.
Now, what I would like to see, which is based on what I have been seeing in the REE market would be:
Total REEs of about 2 wt%, with HREEs making up more than 30% of this number. And of course a thick intersection would be nice (> 10 m is not asking to much) ;)
